How to make a hydraulic press with your own hands. Do-it-yourself electro-hydraulic press. Pressing and vibration

In order to assemble a hydraulic press with your own hands, you need to know the principle of operation and design features of the device.

Calculation of pressure in a hydraulic press is made by Pascal's formula.

The principle of operation of the hydraulic press and its use

The unit is designed for processing various products made of different materials. Products are processed using high pressure. The normal operation of the device is ensured by the use of a special fluid. In a hydraulic press, this fluid is under high pressure. The main working elements of the design are two main cylinders, which have different sizes: in the tank of the smaller cylinder, the fluid pressure is increased and transferred to the working cylinder, which has a larger diameter. The cylinders communicate with each other using a special high-pressure pipeline or a special channel. A piston is located in a large cylinder, which is acted upon by a liquid supplied under high pressure. A special oil is used as a working fluid in the design. From the piston located in the working cylinder, the force is transmitted to the working tool, with the help of which the workpiece is processed.

The working fluid of the hydraulic press is machine oil.

To carry out production operations and prevent displacement of the workpiece, each design of the unit is equipped with a stop, which ensures a stable position of the workpiece for processing.

The working cylinder in the design of the device is located most often in a vertical position. The horizontal position of the working cylinder is found in some units with a special purpose.

There are a large number of different models of hydraulic presses that are capable of developing pressure up to several thousand tons. A specific indicator of the applied pressure is selected in accordance with the characteristics of the workpiece and the tasks.

The hydraulic press is used in the process of processing pipes, if necessary, pressing various products, in the manufacture of various pressed products from rubber, wood chips, plastics.

At home, for your own workshop, you can make a hydraulic press with your own hands from a jack.

Features of the design of the hydraulic jack, its advantages and disadvantages

The use of a hydraulic jack as the main working unit to make a homemade press is not accidental. The use of a jack is based on the laws of physics, which state that a liquid under pressure does not compress or decrease in volume. It is this property that ensures the functioning of the jack.

The hydraulic jack works on the principle of a hydraulic press.

Thanks to this property, jacks are able to act on the workpiece without loss of power. The force exerted on the workpiece greatly exceeds the force that a person applies to the jack lever. The press from the jack has a high efficiency rate, which is 80%. The jack in the design of the press allows you to make a significant compressive force. This effect is achieved by a very large gear ratio between cross section working cylinder and plunger of the jack pumping device.

With a large number of advantages, the jack design also has some disadvantages. They must be taken into account when a press is constructed from a jack. One of the most significant drawbacks is the lack of the possibility of fine adjustment of the stem lowering height. In the design of the press, this leads to the fact that after each use of the installation, it is required to bleed the pressure to zero in order to reuse the press.

The most suitable assembly for the design of the press is a single-rod bottle jack. This type of jacks has a relatively small size. Using it in the design of the press allows you to design a hydraulic jack with your own hands, which is small in size, which makes it possible to place the installation in a small home workshop.

Materials and tools needed to assemble the press structure

For the manufacture of the press does not require special tools. A beginner may only have difficulties with the operation of the apparatus for welding. To simplify welding work, it is recommended to use an inverter welder.

In the process of manufacturing the device, the following tools will be required:

It is convenient to do welding of hydraulic press parts with an inverter welding machine.

  • welding machine;
  • electric drill;
  • screwdriver;
  • level;
  • roulette;
  • hacksaw for metal;
  • grinder with a disk for metal.

To carry out successful assembly operations of the device, it is required to prepare a certain set of materials in advance. To work, you will need to have available:

  • hydraulic bottle jack with a force of up to 10 tons;
  • a set of electrodes for welding;
  • hacksaw for metal;
  • thick-walled profile pipe having a rectangular cross section;
  • metal corner 50x50;
  • a metal strip having a thickness of 10 mm;
  • a piece of pipe for the manufacture of the head of the jack rod;
  • metal plate 25x10 cm with a thickness of 10 mm;
  • two springs to return the stop.

Before proceeding with the manufacture of the device, it is necessary to think over the design in detail and prepare design drawings indicating all dimensions.

Do-it-yourself hydraulic press assembly

In order to make the unit, you should prepare a good manual hydraulic jack.

The main structural element is the frame, which is manufactured in strict accordance with the drawing. Structurally, the bed is a frame inside which a jack is mounted. When designing the bed, it is necessary to provide for a sufficient margin of safety so that it can withstand the pressure that is exerted on it during the operation of the unit. Otherwise, it may break at the welds or deform.

The bed must be very strong: it takes all the effort in the press.

A good margin of safety is achieved through the use of thick metal profiles in the design of the frame with the installation a large number stiffening ribs. In the manufacture of the frame, great attention should be paid to the welding of welded joints. This is required so that in the process of working with the press there is no destruction and deformation of the structure.

The base of the bed is made in the form of a platform, the width of the platform is selected in accordance with the workpieces that are planned to be processed using the manufactured unit. For the manufacture of vertical racks of the bed, a profile pipe is used. The height of the racks is calculated depending on the maximum length of the stem of the height of the bottle jack and the thickness of the removable stop. The length of the stop must be equal to the length of the support platform.

Platform, racks and bottom stop are connected by welding into a single structure rectangular shape. When connecting structural elements, angles should be controlled: they should be straight.

After manufacturing a rectangular frame, a removable stop is made: this element will move freely in a vertical plane with the help of guides and exert pressure on the workpiece. To make the stop, you will need several strips of steel with a thickness of at least 10 mm. The strips are welded together on one side.

To install a removable stop on the frame, steel plates are fixed to the block with bolts. Plates at correct installation are located on both sides of the racks of the bed and limit the free movement of the removable stop from side to side.

The jack is fixed between the platform and the stop. Fastening must be carried out in such a way that the end of the jack rod in the lower position is inserted into the stop lock. The base of the jack is bolted to the stop.

Making a press with additional settings

There can be many variations of homemade hydraulic presses.

In some cases, when using a press, it becomes necessary to reduce the length of the free play of the jack rod. For this purpose, it is required to reduce the distance between the removable and lower stops.

Reducing the distance is achieved by installing an additional, transitional profile with a square section. The length of the profile is equal to the distance between the side posts of the unit.

The second method of regulation involves the creation of an additional stop at the bottom of the unit. For its installation in the side racks of the frame, holes are drilled opposite each other at the required height. The movable stop is fixed at this height by using bolts.

If it is necessary to reduce the distance between the stops of the press, various linings and anvils can be used. The use of each of the methods individually or in combination can significantly reduce the time spent on bringing the movable stop to the workpiece being processed, which greatly speeds up the implementation of work operations.

The good operation of the unit is ensured by the high-quality work of the jack. For this reason, it is recommended to carry out constant maintenance for this press unit, which consists in checking the performance, cleaning and pumping the device. In addition, during operation it is undesirable to allow leakage of the working fluid.

The hydraulic press is used to obtain high pressure. It is used in many body shops to press various shafts, bearings and gears. Home craftsmen use it to stamp parts made of plastic, rubber or metals. If your workshop does not have it yet, then you can try to make a press with your own hands.

Purpose and functions of the press: areas of application of the device

The press has wide application. Sometimes this is a necessary item in the workshop or in the garage. A small device is often used in car repairs. You can use a press for silent blocks, as well as for pressing out bearings.


Such equipment is used to create briquettes from waste, when gluing two surfaces, as well as for bending metal parts. At the same time, factory devices can be unaffordable for many. If you decide to make such a device with your own hands, then it can be easily adapted to certain tasks.

The principle of hydraulics makes life much easier. Thanks to a simple mechanism, various equipment works effectively.

So, let's take a closer look at why such a device is needed:

  • pressing out different bearings, it is used in small auto repair shops;
  • bending hardware of various shapes;
  • providing pressure to bond the two elements;
  • rivet installation.

Try to make a press with your own hands in. Such a device is used for pressing and pressing all kinds of parts. At the same time, the equipment performs a huge range of repairs, maintenance and preventive maintenance.


Let's look at some options:

  • even a small car service needs hydraulic press, which you can buy or make on your own. To make such a unit, you need to decide on the installation of a pressure gauge, the mass, dimensions and performance of the piston. Before developing a press, you need to consider car models. A simple design is not suitable for large machines;

  • often needed for workshop and home waste paper press. If there is a large accumulation of paper, it must be disposed of. This design has an average power rating and can operate from electrical network. With the help of a small device, you can remove a significant amount of waste paper;

  • useful and cardboard press, with which you can press plastic bottles and cans. When installing the device yourself, you need to take into account the parameters of the piston, bed, equipment dimensions and weight. Such a device uses ready-made or manual hydraulic;

  • sawdust press used to create briquettes. The resulting briquettes are used for heating private houses. Such a device consists of power frame, base and drive. A jack is often used for a manual mechanism, and an electric motor is suitable for a mechanical structure;

  • homemade hay baler is a special box that is installed on frame structure from . Such frames can be made from a metal profile. The design is made in the form of a box, but without the upper part. You will need some materials to make your own hay press. Dimensional drawings will make the task easier. It is worth using corners, metal slats and.

To make a hay machine, you need to connect the boards using metal corners. After that, the box is upholstered with slats. This will give strength to the product. Then you need to go to the gate or door, which is fixed on the hinges.

For assembly, you will need an element for attaching to the front, a base for mounting all the nodes, a running part and a transport pick-up. You will also need a special camera with a gearbox and hay. The roll-type pick-up device is used to carry out one cycle of packing and collecting straw or hay.

At the same time, a selection of dried hay is made in the field, as well as pressing the selections. Then rolls are formed from the canvases. Such a process is distinguished by baling without deforming the vegetation. Factory pick-ups have a rather complicated device, which is rarely done at home.

Waste paper units are used in points that are engaged in the acceptance of various secondary raw materials. This unit is different high blood pressure about 15-50 tons, which helps to make bales small size. For their loading, you can use any manipulators. Presses for fuel briquettes also have great power.

Such a structure can be made of two types:

  • the mechanical version is a simplified design with low power. In this case, the force can reach one ton;
  • more powerful ones include a home-made hydraulic apparatus, the power of which can be up to 4 tons.

Similarly, the production of a press for plastic bottles occurs.

Press design: features of existing devices

To create a significant effort on a certain area, the design of a hydraulic press is used; you can buy such a unit in specialized stores. Such a device is an effective and simple device.


If you decide to make such a design according to the drawings, then you need to figure out what it consists of:

  • the bottom or base is necessary for the stability of the structure. It looks like a platform and is made from massive rolled metal. For this, corners made of metal and channel are suitable;
  • racks are vertical parts of the structure. The height of the elements is calculated as the sum of the length of its rod, the height of the jack and the thickness of the fixed stop. Racks are made of steel corners welded to the base;
  • the fixed stop is fixed in the upper part of the uprights. To make it, the same corner is used as for the racks;
  • the jack allows you to develop the necessary effort. This element is attached to the movable stop. It is driven by an electric drive or manual control;
  • the movable stop exerts the main pressure on the mechanism. It can be made from corners or strips of steel;
  • the return device is used to move the movable stop to its normal position. In this case, springs are used, the degree and length of stretching, which is calculated depending on the parameters of the press.

How to make a simple design can be seen in the video below:

vacuum press

When making a vacuum press with your own hands, it should be borne in mind that the device consists of a thermal module, a table and a vacuum chamber. In this case, the last element often has the shape of a rectangle and is made of a rigid material.

This design has some features:

  • the device has only manual control;
  • available materials are used for work;
  • the speed of work should not be inferior to factory counterparts.

The vacuum design is assembled from the following parts:

  • the bed is made of a rail for a thermal module and a profiled pipe. For work, you will need an electric drill;
  • a vacuum table is made from a clamping frame, clamps and a bath;
  • a water ring pump is also needed.

By analogy, a thermal vacuum press is also produced.


Press picker

An apparatus such as a baler is installed as a trailer for. It is used in small farm fields and large agricultural areas. After the green mass is cut off by the mower, this device is engaged in its processing. At the same time, rollers are formed from the stems, and after that, using the unit, pressed bales are obtained.

Here are the advantages of using such a unit:

  • drying time is reduced, and hay losses are reduced;
  • labor costs are reduced several times;
  • improves the quality of hay during storage;
  • independent adjustment of the hinged device is possible.

The most common option is the roll mechanism. Spring teeth allow you to collect a lot of grass. After that, each portion is rolled into bales. A minitractor with the help of such a press can load up to 20 tons of straw in 20 days. Roll structures have small dimensions.

The roll press type makes briquettes in the shape of a rectangle. The grass in the windrows is picked up by the tines and sent to the pressing chamber. Dimensions can be adjusted by technology. The bales are tightly packed and tied with twine. After that, the block is thrown onto the field.


Can be done and homemade version from running timber and lumber. In this case, a large box is made of boards and a horizontal method is used to load hay. As a press, a rack or screw jack. With the help of such a device, you can knit straw bales and press them.

Tabletop mechanical press

The desktop press can work both on automatic, and on manual draft. Such equipment is often made of durable steel.

By means of a manual press are processed:

  • polymers and plastics;
  • cardboard and foam rubber;
  • all kinds of metals;
  • rubber and leather.

With the help of a mechanical press, bearings and bushings are pressed out, stamped, as well as die-cutting of small products. Such a unit allows you to save time on the manufacture of parts.

The device of the hydraulic manual device produces force with the help of a hydraulic cylinder rod. This element contains a liquid that is compressed under pressure. The unit is used to compress, deform and connect parts.

The punching option is used for punching holes in sheets of different materials. Manual mechanical devices are necessary for crimping tubular sleeves and cables.

vibropress

Vibropress allows you to reduce the time of holding construction works and reduce their cost. The device device assumes the presence of three drives: hydraulic, mechanical and pneumatic. The vibpressing technology is at the heart of the unit operation.

Even if you have instructions and the necessary drawings, creating a vibropress with your own hands may not work. This can happen due to incorrect calculations, inaccurate setup and low productivity.


Press with electric drive

The hydraulic press with electric drive has a simple device. Most often it consists of a thick corner and a channel. All elements are connected with thick bolts.

Particular attention should be paid to the frame, as it will be subjected to significant mechanical stress. In this case, the thickness of the metal must be sufficient.

Such a device is often used in production and industry. The force is generated by the operation of an electric motor. The use of such a mechanism helps to reduce the time of the set technological processes.


Garage hydraulic press device: main characteristics

How to make a hydraulic press sometimes you need to know to make such a unit for your garage. At the same time, practical designs can be made from improvised raw materials. For the garage unit you will need manual drive, as well as hydraulic . It is necessary to decide on the type of installation: it will be desktop or floor. A drawing with dimensions will also come in handy.

For the production of a hydraulic press, it is important to decide on the model variant. Here they can be:

  • complex hydraulic design requires specialized equipment and time to work;
  • manual mechanism can be done independently;
  • the standard tire design is two-speed and has hand pump. The piston is mobile;
  • the floor model is equipped with an overload valve and a manual pump drive.

For self-manufacturing you will need a cutting tool and. The advantage of the garage assembly will be the ability to control each stage of installation work.

It is important to determine the type of construction. Horizontal devices are used for bending, straightening and cutting individual elements. And vertical equipment is required for pressing out and pressing parts. The hydraulic plant is used for waste disposal. At the same time, waste paper, plastic waste and corrugated cardboard are pressed.

Also, devices can be desktop or floor. In this case, the desktop mechanism can be installed on a workbench. The presses differ in carrying capacity.

Floor structures have a wide range of desktop adjustment. This option can have a load capacity of up to 20 tons. With their help, disassembly and assembly of nodes is carried out.

There are special safety rules for working on such equipment:

  • for work, you should work in clothes without parts that can get under the press. It is important to protect the hair from such a hit;
  • special glasses are used for the eyes;
  • in the working area there should be no children and strangers;
  • parts are placed in the center of the press;
  • only high quality oils are used for jacks.

An important drive is a manually operated hydraulic pump. He is able to perform reciprocating movements in the working part. Hydraulic cylinders can be plunger and piston. This largely depends on the quality of the liquid used.

To make a simple assembly for the garage, you need a bottle jack. For a small workshop, you can choose a mechanism that can create a force of up to 10 tons. This will reduce the size of the device. You will also need a welding unit, and discs for cutting metal.

Before assembly, it is important to choose only a good jack and make a solid base for it. Such a press consists of a hydraulic pump, a pressure gauge, a frame with a bed and a hydraulic cylinder. In some designs, the cylinder and pump may be replaced by a jack.


The hand press has the following advantages:

  • simplicity of the device;
  • lack of safety mechanisms;
  • the location of the desktop does not affect the working force of the structure;
  • there is a possibility of adjustment of length and height of the working course.

The disadvantages include the insignificant speed of the working surface.

How to make a device for the garage can be seen in the video:

Do-it-yourself hydraulic press drawing options

An important part of any press is the frame. To make a manual hydraulic press with your own hands, the drawings must be chosen very responsibly. The bed consists of a frame, inside of which there is a jack with a tool.


The hydraulic press frame must have increased strength, as it will experience loads in two directions at once.

The lower part of the frame is designed to ensure the stability of the entire structure. To calculate the internal opening of the frame, parameters such as the thickness of the operating mechanism and the free play of the stem are summarized.


To increase the height of the workpiece, it is necessary to ensure the adjustment of the free rod of the jack. Here is what you can do for this:

  • in the upper part of the frame contour, another plate is installed, which can move along the guides;
  • a removable emphasis is made for a mobile platform;
  • from a solid piece of metal, you can make several gasket inserts.

If the correct drawing is used, the hydraulic press will turn out to be of high quality and durable.

Do-it-yourself hydraulic press: how to make

Figuring out how to make a press with your own hands is not difficult. To do this, you need a welding unit, an angle grinder, and a steel profile. A jack is required for the manufacture of a hydraulic device. The shape of such a mechanism should be bottle.


When making a homemade hydraulic press, you will need a jack weighing from 2 to 100 tons. Depending on the purpose, the press can be both floor and desktop. The last option is more compact.

To make a hydraulic press with your own hands, you will need a grinder, a welding machine and a metal drill, as well as drills of different diameters. All kinds of channels, corners and pipes made of metal are used as the starting material. Any hydraulic press consists of movable and fixed elements. The movable ones include return mechanisms and a movable stop, and the fixed ones include racks, stops and a base.


The base of a hydraulic press for a garage can be made from any materials at hand. In order for the structure to be stable, it is necessary to place the center of gravity as low as possible. For a floor device, the base is made of thick-walled corners and channels.

In the manufacture of desktop equipment, you can use a pipe with thick walls and a square section. Iron can be used if the thickness of the metal is about 10 mm. For the base you will need a high-quality emphasis and racks. Such elements are made from improvised materials.

Article

The hydraulic type press is widely used in a wide variety of applications. It is excellent for jobs that require high pressure on parts. In the automotive industry, this condition applies to the processing of shafts, bearings and similar rounded products.

In everyday life, the hydraulic press is used to produce rubber, metal and plastic parts. This equipment is versatile and great for all kinds of work.

In this article, we will ask ourselves what the press can be made of.

Press application

To carry out complex and precise work, special equipment is needed, however, a simple hydraulic press will help solve some problems.


Here are the most common:

  • production of bearings of the required size, perfect for your own small auto repair shop;
  • bending of hardware;
  • maintaining the necessary pressure for gluing parts of the product;
  • assembly of rivet elements.

The best place to install equipment is a garage or suburban area. A photo of the press with your own hands can be seen below.

Hydraulic press for automotive works

Even for holding simple jobs you need to have some skills. It is necessary to correctly take into account the working pressure, as well as the weight, dimensions and other characteristics of the piston mechanism.

The simple design of the hydraulic press is only applicable to cars. For cargo vehicle you need professional equipment. The ideas of homemade presses are unlikely to replace them.

Waste Paper Press

Such equipment, first of all, is necessary for summer cottages and suburban areas. A large accumulation of paper will sooner or later require its disposal.

The installation quietly works from a household electrical network of 220V at medium power levels. The press differs in high productivity even at small dimensions of the equipment.


Press for cardboard materials

In addition to cardboard, it is possible to press plastic bottles and cans. But in such equipment, a hydraulic pump is required.

sawdust press

It is used to obtain sawdust briquettes, widely used in heating country houses. The equipment is large. It consists of a table, frame structure, machine base and motor.

For manual use, a jack is used, and for mechanical use, an electric motor is used.

Hay picking equipment

There are instructions on how to make a press yourself. As preparatory materials, prepare metal corners, slats and planed boards. First, we proceed to the assembly of the box, using boards and metal corners.

This type of press is available in two versions:

  • mechanically is simple design with low power and force up to 1 ton;
  • homemade version of a hydraulic press with a working force of up to 4 tons.

Of course, it’s nice to have ready-made drawings on hand on how to make a press correctly, since for self-assembly you will need fastening elements for the frontal part of the equipment, a base for fastening all nodes, a running guide and a transport pickup.

Self-made hydraulic press

A simple version of a hydraulic press will require a welding inverter, an angle grinder, a hand saw, a metal puncher and a metal profile. A jack is also needed, depending on the purpose of the press, from 2 to 100 tons.


This type of press is made in the form of a bottle mold. Any hydraulic press consists of moving and static parts. Assembly units such as channels, corners and thick-walled pipes are perfect.

As dynamic blanks, return units and a moving stop are used; various types of racks and bases are referred to as fixed products.

Do-it-yourself step-by-step production of a press, especially its base, is possible from any available materials. The center of gravity of the equipment should be placed as low as possible.

When installing the press on the floor, channels and corners with a thick section are used. To mount home-made presses on tables, square pipes are used. Materials from steel alloys are used as the material; the use of iron alloys is advisable with a workpiece thickness of 1 cm or more.

Do-it-yourself photo press

A garage press is a machine that is designed for straightening, compressing, bending sheet materials, pressing or pressing bearings, as well as for other plumbing work.

Those devices that are designed to perform these plumbing jobs have a very simple and compact design, which is different from high-power industrial hydraulic presses. The maximum value of the force produced by such a press, depending on the specific model, can range from 5 to 100 tons.

For use in a garage, an effort of 10-20 tons is enough. This allows you to perform traditional car repairs.

In addition to the developed effort, the press also has such basic characteristics as the piston stroke, the operating range of the bed, the presence of a pressure gauge, dimensions and weight.

The garage press usually uses a manual drive. In other words, the design of the press uses a manual or manual hydraulic pump, which is matched to the power cylinder according to the volume of oil.

The hydraulic press consists of two chambers with pistons connected to each other by an oil pipeline. The principle of operation of a hydraulic press is based on Pascal's law. That is, the pressure force on the workpiece is as many times greater than the applied force to the piston, how many times the area of ​​the piston is greater than the area on which the press rod acts.

There are also pneumatic hydraulic presses that use a pneumatic piston. When connected compressed air it starts pumping oil into the cylinder. In some models of presses for convenience of work there is a pneumatic pedal.

The disadvantage of pneumohydraulic presses is the need for compressed air.

Aggregate types

According to the method of execution, garage presses are floor and table type.

The advantages of a desktop press are compactness and ease of use. Press floor type has significantly larger dimensions, and therefore, it requires additional space in the garage.

Element design

For the manufacture of the bed of the press, thick-plate hardened steel is used. The design is strengthened by powerful stiffening ribs.

The profiled base of the factory-made press, as a rule, has holes for fixing to the floor or table. The height of the desktop in serial models is usually easily adjustable.

For this purpose, a mechanical lift with a rotating handle is provided in the design of presses with a large pressing force. Trapezoidal threaded mechanical rod is used to transfer the pressing force and ensures the reliability of the design. Serial models of presses, as a rule, are equipped with an automatic return of the rod and safety valve, protecting against emergency situations during overloads. The pressure gauge is installed in a place convenient for the operator and shows the current load force.

All elements of the hydraulic system are built into the monoblock design of the press, protecting them from accidental damage. The set of garage presses includes two combined V-shaped plates.

Making a garage press yourself

Hydraulic press device

Experienced motorists often make a garage press with their own hands from affordable and inexpensive materials and component parts. This allows them to independently perform a number of small tasks. repair work: to press bearings, silent blocks, rubber bands of jet rods, etc.

Materials for manufacturing

For its manufacture in the construction market, you must purchase:

  • Channel No. 8 with a width of 80 mm (it is advisable to immediately cut it on the spot to the required dimensions 6 * 500 mm);
  • Rectangular pipe 40 * 60 mm, also cut to size 2 * 1000 mm + 2 * 500 mm;
  • Bolts M8*30 - 4 pcs., M10*80 - 4 pcs., M12*80 -10 pcs., M12*150 - 2 pcs. with nuts;
  • plate 250*250*8mm;
  • Strip 4 * 40 * 60 mm - 4 pcs.;
  • Corner 50 * 50 * 300 mm - 2 pcs.;
  • Corner 25*25*250 mm - 2 pcs.;
  • Bottle jack for 12 tons;
  • Bridge fungus with shifted splines;
  • 2 door springs 300mm each.

It is possible to additionally arrange a bearing puller on the basis of the press. For this you will need:

  • Hairpin M16 * 1000 mm - 2 pcs.;
  • Hairpin M8 * 1000 mm - 1 pc.;
  • Nut high M16 - 4 pcs.;
  • The puller is two-legged small.

In principle, the purchase of metal products can be made at the metal depot, choosing the required sizes among the remnants of illiquid assets. As a rule, such materials are much cheaper.

Holes are pre-drilled in the channels and corners. Then a homemade garage press is assembled from metal blanks using fasteners. The bottle jack performs the main role in the device - it generates the pressing force.

To do this, it is placed on a movable desktop. The jack can be removed from the press at any time and used for its main intended purpose. The movable work table is supported by 2 suspended door springs. From below, a bridge mushroom is attached to it with M8 bolts, which will act as a rod. For the manufacture of the upper part of the puller, two strips 40 * 4 * 60 mm are welded to a high nut under the stud. Two puller hooks are welded to two studs.

This design of a home-made garage press is as simple as possible and allows, if necessary, to independently disassemble it and transport it to another place.

The cost of industrial products of the hydraulic press is such that rarely anyone wants to buy it for "home and family". Such models are used, as a rule, in production or in workshops (in the sector of medium and small businesses), and then in specialized ones (forge, car service, etc.).

A “solid” apparatus is not sold for less than 170–180 thousand, and small devices called “press tongs” (within 2–3 thousand rubles) are of limited use, mainly for “crimping” metal products.

You can buy a press for 25 - 30 thousand rubles (made in China), which is not so expensive these days. But if you look closely at how and from what it is assembled, then the thought involuntarily comes that all this can be mounted from improvised materials. If you have to "spending", but very little.

There are many options for self-manufacturing hydraulic press. Each owner, depending on his needs, determines his dimensions, configuration, the limit of the “stroke” of the working part, the necessary force that hydraulics must provide. Let us dwell on one, simple to manufacture model of such a product.

We will not indicate specific dimensions, the main thing is to understand the principle of assembly and operation of the device. And any skilled person will figure out for himself how and from what it is more convenient for him to make a press. The essence of the work is as follows. There are 2 containers (vessels) in which there is a liquid (as a rule, this is a special oil). They communicate with each other (remember the lessons of physics at school). By applying a small effort to compress the liquid in one (small vessel), we get pressure in a large one, several times higher than the “primary” one.

If you put a rod in it, then it will move. Any part located between the support (on the frame) and the working "tool" (rod) will be under pressure. In other words, we press on the handle, and the workpiece is flattened. And the more, the stronger we act on the lever. Everything is simple.

The photographs show the press on different stages manufacturing. Therefore, it makes sense to dwell only on some features of the assembly, and it is not difficult to determine what materials are needed, based on its capabilities and the specific purpose of the device.



Components of the mechanism

Base

It must be strong, since it is on this part that the maximum load will fall. It is possible, for example, to weld a frame from a corner, inside which, to increase strength, weld segments of the same corner or a thick metal bar (pins, etc.). It should be taken into account that a hydraulic jack will stand on such a frame (platform), therefore, on the upper surface of the frame, it is necessary to fix the cut sheet of iron by welding. Its thickness depends on how "powerful" the press should be.

Top stop

In fact, it is necessary to make a welded structure in the form of the letter “P”, which will be fixed on the platform with “legs”. Its height is determined by the maximum possible extension of the jack rod. The easiest way for this purpose is to use a thick-walled pipe with a square or rectangular profile. It is necessary to pay attention to the fact that all elements of the stop are located at right angles. Not even the slightest distortion of the "letter" is allowed.

work item

In fact, it plays the role of a lower, movable stop. In the process of pressing the part, it is with him that it will be pressed against the upper stop (“crossbar” of the letter “P”). The principle is clear. How to make, there are several options. For example, to make an assembly of metal plates of appropriate thickness, which are fastened together either with bolts or by the same welding.

In order for this part to move freely up and down and not move at the same time, the length of the extreme plates is chosen more. The resulting "protrusions" on the sides will play the role of position locks along the horizontal axis. In other words, such an “assembly” can move in the vertical direction, but not left-right.

To exclude a large skew of the movable stop, the length of the "internal" plates is selected so that they are almost closely adjacent to the structure pillars (legs of the letter "P"), with a minimum gap.

Afterword

We have given only one of the options. You can make a press in which the stroke of the rod will not be from the bottom up, but vice versa. Naturally, for this, the hydraulic cylinder is placed on the upper stop. At the same time, the center of gravity of the entire structure shifts, so the platform will have to be made more massive, wider.

For the convenience of working with parts of different sizes, it is advisable to prepare "inserts". If necessary, they can be put on the working part, thereby reducing the distance over which the stem will have to be extended.
