General layout of the machine
The basis of the machine is a frame consisting of two racks with a table placed between them. The table and the stand are connected to each other by 3 ties. A clamping beam moves in the guide posts above the table, connected directly to the rods of the hydraulic clamping cylinders; the posts also contain the rotation shafts of the bending beam, which is suspended in a vertical position on 2 screws connected to the rotation shafts. The rotation shafts of the bending beam are connected through a rack and pinion mechanism to the rods of the bending cylinders. A bracket for the back stop mechanism is attached to the rear table, in which a lead screw driven by an electric motor is mounted. The back stop carriage with spring-loaded grips moves along the lead screw, opening under the action of a hydraulic cylinder. The design of the machine provides options for driving the back stop lead screw from an electric motor.
Operating principle of the machine
The sheet to be bent is placed on the machine table, sent all the way, grabbed by grippers, then a pressure beam is lowered down, which presses the sheet during bending. The sheet is bent around a mandrel fixed to a pressure beam. The mandrels can be replaceable for bending parts of various shapes. The bending process itself is carried out by a bending beam, the tool bars of which are located under the sheet being bent. When turning the bending beam, the tool bars touch the sheet and bend it around the mandrel. After turning through a given angle, the bending beam returns down to its original position. Then the pressure beam rises up and the cycle repeats. The clamping beam moves forward under the action of the cylinders. The bending beam rotates from the cylinders through the rack and pinion transmission and shafts. The back stop moves along a lead screw that rotates from an electric motor through a chain drive. Manual adjustment of the back stop is carried out by turning the flywheel, which is connected to the lead screw through a chain drive. The height of the table is adjusted by turning the handle, which transmits rotation through a worm gear to the table support screws. The position of the beam is adjusted by rotating the handle, which, through bevel gears and worm gears, transmits rotation to the nuts and screws on which the bending beam is suspended.
bed
The prefabricated machine bed consists of 2 racks and a table, tied together by 2 lower ties and an upper ties. The stands and table are of welded construction. The table has rectangular projections on both sides for guidance in the racks during adjustment. Brackets for mounting the housings of the table adjustment mechanism are attached to the racks below. At the top of the racks there are brackets in which the clamping cylinders are mounted. Below the bracket, guides for the pressure beam and table and wedges for adjusting the gap in the guides are attached to the rack. Inside each of the racks there are cylinders of the bending beam and a rack and pinion mechanism for driving the bending beam. The bores of the racks accommodate the supports for the rotation shafts of the bending beam. When adjusting the table, it is necessary to lower the tie passing through the table to create a gap between the table and the guides of the racks. To do this, loosen the nuts at the end of the tie. After adjustment, the nuts must be tightened again. To make such adjustment possible, it is necessary to install the clamping cylinders of the table adjustment mechanism and secure the lower couplers while the upper coupler is tightened.
Table adjustment mechanism
Designed to change the position of the table at height. Adjustment is carried out using a handle located on the outer side of the right pillar. When the handle is turned, the shaft transmits rotation through worm gears to the support screw nuts, and the screws begin to move up or down, respectively raising or lowering the table.
Bending beam
The bending beam directly bends the sheet. It is a welded box-section structure, on the top of which tool strips are fixed. The bending beam is suspended on 2 screws, the heads of which are connected to the drive shafts of the bending beam. When the shafts turn, the screws turn along with the beam. The sheet bending process takes place.
Rear stop
Designed to support the rear edge of the sheet during bending.
Bending angle setting mechanism
Serves to indicate the current angle of rotation of the bending beam and set the specified bend angle.
Pipe bending device
To bend pipes, a special device is installed, consisting of brackets fixed to the front surface of the pressure beam and hammers, in which a replaceable round mandrel is installed.
Device for bending closed profiles
Structurally, the device is similar to a pipe bending device, but instead of a round mandrel, a rectangular mandrel is used.
Mandrel for bending U-shapes, boxes and edges
simple in structure and design.
Reception table

Operating principle of sheet bending machine IV2144
The sheet to be bent is placed on the machine table, pushed as far as it will go and grabbed by the grippers.
A pressure beam is lowered onto the sheet and the sheet is bent around a replaceable mandrel fixed to the pressure beam. The shape of the replacement mandrels can be different for each type of part.
The bending process is carried out by a bending beam, which is located under the workpiece.
After turning at a given angle, the bending beam returns down to its original position, the clamping beam rises and releases the sheet.
Sheet bending machine IV2146
The sheet bending machine model IV 2146 differs from other models in that its work table size is four meters. And this makes it possible to use a sheet to prepare a part for the same width.

Listogib IV2144: technical characteristics, principle of operation
IV2144 belongs to the category of hydraulic sheet bending machines. A distinctive feature of the equipment of this model is that its design contains a rotating beam.
Appearance of sheet bending machine model IV2144
The main purpose of the machine model IV2144, which can be equally successfully used in various fields of industry and in construction, is the manufacture of products using cold bending technology from sheet metal. Rolled sheets that can be processed on such a machine are usually made of steel that has not been subjected to heat treatment, as well as ductile non-ferrous metals.
Design Features
The supporting element of the sheet bending machine of this model, on which all other parts of its structure are fixed, is a split-type bed, consisting of two racks and a work table located between them. To give greater rigidity to the IV2144 frame, its side posts are connected with three ties.
The rotary bending beam, which is equipped with a sheet bending machine of this model, has a welded structure and is fixed on the machine in a vertical suspension. Such a beam communicates with the bending cylinder rods through several elements of a kinematic chain (a rack and pinion mechanism connected to the beam rotation shafts, which in turn are connected to the screws on which it is suspended).
Components of sheet bending machine IV-2144
The machine of this model is also equipped with a pressure beam, which also has a welded structure. Such a beam, connected to the cylinder rods responsible for its clamping, moves in a vertical plane along the guides of the bed posts.
Let's consider the technical characteristics of the IV2144 machine, which are especially important for its users.
- The maximum thickness of a steel sheet that can be bent is 4.5 mm.
- The length of the work table, which determines the maximum width of the processed sheet, is 2.5 m.
- The force created by the pressure beam is 40 tons.
- The force created by the rotary bending beam is 30 tons.
- The power of the electrical equipment equipped with the sheet bending machine is 10 kW.
- The maximum adjustment distance for the work table and bending beam in the vertical direction is 10 mm.
- The maximum stroke of the pressure beam is 250 mm.
- The area occupied by the machine is approximately 9 m2.
- The weight of the sheet bender is no more than 9 tons.
Controls of sheet bending machine IV2144
The hydraulic system of the equipment, which includes the following elements, is responsible for the technical characteristics of the pressing and bending beams of the sheet bending machine of this model:
- two main cylinders ensuring the operation of the pressure beam;
- two main cylinders of the bending beam;
- hydroelectric station
The hydraulic drive of the IV2144 machine simultaneously performs several functions: rapid supply of the bending beam to the surface of the sheet being processed, its rapid retraction to its original position and slow movement during the bending process. The position of the pressing and bending beams, depending on the thickness of the sheet being processed, as well as the required bending angle can be adjusted, for which the machine is equipped with manual control mechanisms.
The press is powered by a hydraulic unit model K34007EM
In order to accurately position the position of the sheet being processed and regulate its movement by a given amount, the machine of this model is equipped with a mechanized back stop. Such an emphasis, which is driven by a carriage mounted on it, a lead screw and an electric motor, is attached to the work table of the equipment using a special bracket. In addition, the design of the stop includes hydraulic grips and an indicator of the position of the trailing edge of the workpiece, which allows not only to quickly change, but also to control the position of the sheet being processed.
The back stop of the machine is designed for precise positioning of the sheet during the bending process
To prevent distortions of the presser beam of the machine during its movement between the racks, the design of the sheet bender provides a synchronizer, consisting of a shaft with gears attached to its ends. The synchronizer, together with the pressure beam, moves along rails fixed to the machine racks, the adjustment of the position of which ensures the accuracy of such movement.
The most heavily loaded sheet bending mechanisms are lubricated using a centralized system, and less loaded ones are lubricated using a syringe mechanism. To control the operation of the machine, its design provides two remote controls, one of which is mounted on its right stand, and the second on a hinged control device.
Using the working tools of a sheet bender, which are supplied as standard, you can perform simple bending operations on metal sheets (internal bending angle – 32–180°, bending radius – 7 mm). If such a machine is equipped with additional interchangeable devices, then it can be used to successfully create products of even quite complex configurations from metal sheets - pipes and other closed contours, parts with a U-shaped profile, boxes, etc.
How does the sheet bending machine IV2144 work?
If we briefly describe the operation of this machine, it looks like this: the deformation of a sheet blank is carried out through the influence of a bending beam on it. In this case, the formation of the product of the required profile is ensured through the use of appropriate mandrels, which are fixed on the pressure beam.
The standard bending mandrels of the machine can be replaced with other interchangeable devices for bending closed loops or pipes
The step-by-step operating diagram of the sheet bender of this model is as follows:
- The metal sheet to be processed is placed on the machine's work table, advanced until it comes into contact with the stops and secured using hydraulic clamps.
- A clamping beam with a replaceable mandrel fixed on it is lowered onto the sheet, the configuration and dimensions of which depend on the required bending shape.
- The metal is deformed by a bending beam, which is located under the sheet being processed.
- After processing is completed, the bending beam is lowered to its original position, and the clamping beam releases the finished product.
