Possibilities of sheet bending machines with a rotating beam. Sheet bender with a rotating beam used Hydraulic machine - when oil can bend metal
The workpieces are bent by rotating the bending beam to a specified value. The edge is bent around an insert that has a certain working radius, which is equal to the bending radius of the part. Rotary beam bending machines can produce bends as low as 136°.
The maximum length of the edge that can be bent is determined by the working overall length of the equipment. These machines are famous for the simplicity of the technological equipment used and their wide versatility. Their performance makes it possible to ensure normal productivity in small-scale and single-piece production.
Sheet bending machines with a rotary beam are in demand in those industries where cold bending is necessary. Models such as IV2144, IV2146, IV2143 and IV2145 are equipped with a rotating beam.
Design features of rotary beam press brakes
- These machines have a clamping and bending beam, a bed, an electric drive for guiding the clamping and bending beam, a back stop, etc.;
- The purchase of additional replacement devices for press brakes allows the production of parts with different configurations from cold metal sheets;
- To work with actuators, that is, with bending and pressing beams, it is necessary to purchase a hydraulic unit;
- A special mechanism is used to adjust the machine table and bending beam. It allows the machine to work with different sheet thicknesses. Typically, the process of adjusting a bending machine is done manually;
- To fix the rear edge of the sheet during bending or to move it to the required size, you must use a back stop;
- To prevent distortions and protect the pressure beam, a synchronizer is used. This is accomplished by a shaft equipped with gears attached to its ends. The gears interact with the racks. And the slats are fixed in the racks of the frame.

If you have long dreamed of working with metal, creating products of unusual shapes, be sure to read the material presented below. We will look at what a sheet bending machine with a rotary beam is and many other types of similar units.
1 Sheet bending equipment today – what is it like?
The purpose of these devices becomes clear from the name, but let’s still spend a few minutes on the terminology. So, these are machines for bending and cutting metal sheets. We first heard about such a device in the 19th century, and it is not surprising, because it was during this period that a significant leap occurred in industry, and there was an urgent need for new structural elements, parts and spare parts.
The first units were exclusively manual, mechanical, and at most had a hydraulic drive. But since the second half of the last century, their range has expanded significantly and today electromagnetic and electric sheet benders are in demand. It should be noted that initially they were used only in large industries, factories, large factories, etc. Today, you can find neat small machines in private workshops. Sometimes they are purchased for home use.
Depending on the working tool, the equipment is divided into roller, rotary beam and roller benders. Moreover, the number of rollers and rollers may be different. The installations can be mobile, small in size and weight, or very impressive stationary. The mass of the latter reaches several tons. Another feature of such devices is the type of drive. Mechanical, hydraulic, etc. are known.
Recently, the way work is managed has changed and the advent of CNC press brakes has created an explosion in the global market. All equipment, from the simplest to the most complex, has almost the same technological scheme. The clamping beam fixes the sheet, and the bending beam forms the required profile; all parameters are set and controlled electronically. The thickness of the work sheets reaches 10 mm. Greater productivity can be achieved by combining convenient control with a powerful drive, for example, a hydraulic one is often found.
The CNC press brake has several advantages. First of all, this is digital control. In case of dangerous approach, electronic protection is immediately activated. Laser beams outline the danger zone, and as soon as at least one of the lines is crossed by a hand or other object, the movement of the cutting tool immediately stops. But this is not all the advantages; you can load product drawings from a computer into a CNC press brake or select from a parts library. The clamping position is controlled automatically, and the speed and angle are also adjusted. If you wish, you can update the software yourself. Moreover, the equipment has a USB output.
2 Which installations are driven by electricity?
The electromechanical sheet bending machine is a stationary machine. Its feature is the presence of a gearbox and an electric motor. It has found its application in many fields, especially in construction. It is on equipment with an electric drive that façade cassettes, ridges, ebbs, caps for fences, etc. are produced. It should also be noted that there is a wide range of materials that an electromechanical sheet bender can handle. These are steel, copper, aluminum; metals with protective coatings will not cause problems.
The crank press brake has impressive dimensions, so it cannot be called a garage unit. The weight of these machines exceeds 9 tons. It is used in shipbuilding, automotive, mechanical engineering and many other industrial fields. Such installations produce not only bending, but also profiling of metal sheets. You can also do hole punching and stamping. Special dies allow you to work with products of complex shapes. And due to the slider and the protruding part of the table, it is possible to bend rectangular or cylindrical parts with a closed contour. The package also includes a special V-shaped stamp. The drive of the device consists of an electric motor, a brake clutch, a V-belt transmission and a gearbox with two speeds.
Electric segment benders consist of a frame and two beams with electric motors. For greater convenience, there is also a cabinet with foot control. The main advantage of a segment bending machine is a huge set of attachments that differ in width. And the complete absence of any restrictions on the rear side allows you to work with elements of various lengths and widths.
3 Hydraulic machine - when can oil bend metal?
In this case, the energy carrier is liquid. The hydraulic drive means that it is pushed out under enormous pressure from the master cylinder and moves the cross member. It is most advisable to use such equipment when it is necessary to bend a metal sheet along the entire length of the work table. Positioning accuracy 0.01 mm. It can be stationary or portable, so its use is very common in various fields.
The three-roll sheet bender, which has a hydraulic drive, is extremely popular. It got its name from the number of work rolls. These installations are distinguished by increased precision; the bending angle is set with a special clamp and strictly maintained. The advantages include efficiency and speed. Small dimensions combined with fairly high power make this hydraulic unit attractive for established enterprises and home use.
Today, digital control and hydraulic drive are combined, this CNC press brake, thanks to the latest technology and high-quality components, has excellent performance, so it is suitable for use even in very large enterprises. A special feature is a complex of devices and software that receive corresponding signals from various devices, and they, in turn, read them, process them and control the technological process.
4 For lovers of physical activity
This includes the simplest guillotine sheet bending machine, which can often be found in small workshops or private garages. It is not large in size, but allows you to work with metal up to 3 mm thick. Basically the bend angle is small. However, there are units that allow you to bend thin-walled metal 360 degrees. With a guillotine, even at home you can make quite complex elements of a conical or cylindrical shape, from which drainage systems, air ducts and various decorative products are subsequently assembled.
The most popular manual roller bending machine today. It is very easy to work with him. You just need to insert the workpiece between the bending rollers, and then make the necessary bend with smooth translational movements. True, the angle does not exceed 90 degrees, but the length is not limited. Some requirements also apply to the source material. The thickness of the sheets should be no more than 0.8 mm. Such units are lightweight, usually not exceeding 2 kg, so you can freely take the roller bender directly to the site, even to the roof.
By the way, among manual models there is also a sheet bender with a rotating beam. It is, of course, more bulky due to its design.
5 Pneumatic and mechanical equipment
The pneumatic press brake operates through the action of pneumatic cylinders, thereby greatly facilitating the work. Despite this, it is not in great demand among enterprises. After all, his effort is not enough to produce long products or work with thick-walled sheets of metal. So its main focus is roofing steel products and packaged elements. The dimensions of such equipment are rather large, so hardly anyone would want to purchase it for home use.
Mechanical sheet benders have been popular since the last century. The operation of these machines is ensured by the mechanical laws of physics, so their cost is minimal. Such installations are durable and reliable. They are controlled by a pedal. The bend angle does not exceed 180 degrees. There is an opinion that these units are very cumbersome, but everything is relative. If you compare them with huge crank machines weighing several tons, then such equipment will seem compact - only 200 kg.
6 Electromagnetic unit - modern trends
It remains to talk about electromagnetic sheet benders; they appeared relatively recently and have proven themselves to be the best. Their main difference from manual machines–a heavy-duty electromagnet, which is responsible for reliable fixation of the sheet material, and not a bulky beam, as was the case in earlier models. Thanks to this original solution, the capabilities of the equipment have significantly expanded and its dimensions have decreased.
The electromagnetic machine has an unlimited bending angle. Moreover, now you can work with metal 1.6 mm thick. Due to the pressure of 4.5 tons per square meter. m ensures a perfectly flat surface of the profile without defects. The absence of mechanical friction has only the most positive effect on the wear resistance of the machine. The electromagnetic unit allows you to produce various parts, even of complex shapes, especially since the package includes three types of beams - narrow, solid and segmented, and the foot pedal greatly simplifies the work.
The automatic sheet bending machine has a special electromechanical drive and is used for working with metal products with a thickness of 1.0 to 7 mm. Structurally, electric sheet benders are represented by a powerful frame welded on a durable frame, on which the pressing and rotating bending beams are mounted. If you want to buy an electromechanical sheet bending machine with an electric drive, you should keep in mind that in most cases it is a stationary mechanism.

The production of various dimensional products from metal sheets by bending is carried out using various methods - manual, hydraulic, pneumatic. The rotary beam bending machine is one of the most productive and easy-to-use tools with a high level of versatility.
It can be used to make not only large-format parts - boxes, bottoms, rectangular pipes, valleys and other roofing elements, but also to bend edges, strengthen bottoms and perform work on the production of conical and prismatic parts.
The machine is built on a rectangular frame made of steel channel, on which a pressure beam and a movable punch are installed, which can rotate around a horizontal axis. You can understand the operating principle of a machine with a rotating frame by looking at the drawing and diagram:
Having placed a sheet of metal up to 1.5 mm thick (depending on the model) and up to 2 m wide on the work table and pressing it with a beam 4, the operator lifts the handle 7 up and turns the punch 90-120 0 .
Acting on the sheet, the punch bends it along a straight line at the angle specified by the operator. At the same time, the metal does not break or go ragged - the bending line turns out to be extremely smooth.
The front edge of the support beam is beveled back at an angle to the vertical plane from 85 to 45 0. To bend thick sheets (1.5 millimeters or more), a sheet bender with a rotating beam can be equipped with a clamp with a straight front edge (perpendicular to the base). This eliminates the possibility of bending and ensures sufficient bending accuracy.
Advantages of bending machines with a rotating frame
This type of sheet bending machine is produced in various designs:
- manual;
- mechanical;
- electromechanical;
- hydraulic;
- electromagnetic
The first three types can be found on sale in manual, mobile and stationary forms. With the proper skill and desire, you can make a sheet bending machine with a rotating beam with your own hands in a garage, home or industrial workshop. As a basis, you can take drawings on specialized websites on the Internet, or one of the industrial machines. Among them there are interesting models, characterized by simplicity of design and breadth of capabilities.
Manual machines are very convenient for working on construction sites when performing roofing work or installing drainage and ventilation systems. With their help, you can easily make a window sill, a drip tray, various non-standard additional elements, and stiffeners. For small-scale production in a workshop or workshop, using a manually driven machine is quite tedious - here an electromechanical option or a mechanical one with a foot drive is more appropriate.
Hydraulic machines are produced in a stationary version and are used for large-scale production, although they can also be used to produce a separate part of a complex configuration without any problems.
The main advantages of bending machines with a rotating frame include:
- simplicity of design;
- wide range of adjustments;
- the ability to bend painted and galvanized sheets without damaging the coating;
- bending along non-parallel lines (segmental);
- low cost.
Many factory-made sheet benders have the ability to rotate the pressure beam around a horizontal axis for further bending up to 180 0. Segmental models of machines are equipped with replaceable attachments (segments) on the pressure beam, which make it possible to produce products of complex configurations, for example, facade cassettes or dome tops. It is enough just to replace the typesetting segments and the bending line changes.
Industrial machines are equipped with moving along the front of the work table. Knives allow you to cut a strip of the required width or a finished part from a sheet. In industrial production, most sheet bending machines allow work with workpieces of unlimited length up to 3 meters wide. The cutting roller knife allows one person to work with rather bulky parts.
Industrial bending machines with rotating frame
In addition to machines from Germany and France, which will be discussed below, Russian-made sheet metal bending machines, for example, the EVA series, remain popular on the market. They have an electromechanical drive and the ability to segment bend. Their characteristics:
- Pressing beam opening speed 50 mm/s;
- Automatic raising and lowering of the clamp;
- Automatic beam rotation;
- Set of segments 50-600 mm;
- Rigid frame with deflection compensator;
- Workpiece width - 3 m;
- The length of the sheet is not limited.
Machines are produced in a wide range of models with a possibility of from 0.8 to 1.5 (2.0) mm, including painted, galvanized and non-ferrous.
Among the good qualities are the RLGS machines, designed for bending sheets up to 1.5 mm thick, 2500 mm wide (in the standard version) and unlimited length.
Upon request, the factory can make a machine for working with sheets up to 3000 mm. But it must be taken into account that the required physical strength of the operator depends on the width of the sheet. Three-meter sheets with a thickness of more than 1 mm are quite difficult to bend. Such machines are best used for bending galvanized and non-ferrous metal with a thickness of no more than 0.7 mm. The machine is equipped with a working protractor, which allows bending with high angular accuracy.
Listogib IV2144 is built on the basis of a hydraulic system. This is an industrial stationary machine for large-scale production. A sheet bending machine can work with sheet metal up to 4.5 mm thick, which is beyond the capabilities of electromechanical and manual machines. Hydraulic cylinders work on the pressing and rotating beams, which determines high bending accuracy, smoothness and, at the same time, speed of work. Control is carried out using two remote controls - on the stand and mounted on a hinge.
Chinese sheet benders ACL have a very promising future in the market. At a fairly reasonable price, the sheet bending machine has advanced functionality and can work in both hydraulic and manual modes with sheets up to 4 mm. In many respects, the machines of the new models are not inferior to European equipment.
