Well, now we’ll tell you about a more powerful model of manual sheet benders LZPO - the LGM-35 bending machine.

Principle of operation

The technological operation of sheet metal bending when using the LGS 26 sheet bender is performed in the following sequence:

1. A workpiece is placed on the frame of the machine (under its matrix), the geometric parameters of which should not exceed the values ​​​​specified by the equipment manufacturer.
2. The workpiece is placed on the frame in accordance with the markings and then securely fixed.
3. Using a rotating punch, the workpiece is bent to the required angle.
4. If it is necessary to bend not one, but several workpieces to the required angle, then for this you can use the rotation angle limiter of the punch, located on its handle.
5. If the workpiece needs to be bent at a greater angle than the main bending mechanism allows (up to 180°), then for this you can use the bending device located on the back of the LGS 26.

In order to cut sheet metal on a machine of this model, you can use a special disk-type machine, which is included in the standard equipment of this equipment.

The cutting machine knives are designed for reusable use and can be sharpened on any surface grinder

The operating principle of such a machine, the design of which, in addition to circular knives, consists of lower and upper rollers, mounting bolts, which are also used to adjust the position of the device, is as follows:

• The metal sheet, as before the flexible one, is pressed against the equipment frame by a matrix.
• The machine with which the cutting will be performed is mounted on the bending guide.
• By moving the cutting machine from right to left, the sheet is cut.

The process of cutting an edge using a cutting machine

In order for the machine model LGS 26 to provide high-quality results when cutting and bending on it, its mechanisms should be correctly adjusted before starting work. Thus, it is necessary that the axes of the matrix and the axes of the guide relative to the axis of the rotary punch are strictly parallel. For such adjustment, adjusting bolts are used, which also perform fastening functions. During processing, there should be no foreign objects on the working surface of the sheet bending machine that could not only interfere with the quality of processing, but also cause equipment failure. Of course, when working on the LGS 26 sheet bending machine, you should also strictly follow the general safety rules.

To ensure safe operation of the machine of this model, as well as to maintain it in working condition, it is necessary to regularly carry out its maintenance (TO-1 and TO-2). As part of TO-1, which is performed daily, the surface of the machine is cleaned of dirt, dust and metal residues. The correct operation of all structural elements of the equipment is also assessed. TO-2, carried out monthly, involves not only inspecting and testing all mechanisms of the LGS 26 sheet bender, but also tightening all fasteners in its structure.

Most common faults

Let's look at the most common malfunctions that the operator of the LGS 26 sheet bending machine may encounter.

1. Incorrect operation of the cutting mechanism can lead to a shift of the cutting line to one side. This malfunction can be eliminated by simply adjusting this mechanism. In this case, you can be guided by the diagram available in the equipment passport.
2. The formation of a gap between the bending machine frame and its matrix leads to uneven bending angle of the workpiece along its length. This kind of malfunction is also easy to fix: just adjust the resulting gap.
3. There may also be disturbances in the convergence pattern of the knives and their dullness. This leads to difficulties in the process of cutting metal sheets. The first malfunction is eliminated by adjusting the convergence pattern of the knives, and the second - by removing them from the machine and carefully grinding them.

When the cutting machine is withdrawn, the adjusting bolts 1 are loosened and the roller 3 moves in the opposite direction from the withdrawal

In general, expert reviews of the LGS 26 sheet bending machine are positive. No special training is required to operate it, and its maintenance is not particularly difficult. The main thing is not to violate the operating standards of such a device and carry out its maintenance in a timely manner.
