When operating a hydraulic sheet metal bending machine, we must first understand its operation method, that is, its technological process. In actual operation, its technological process is mainly divided into oil pump startup, downward movement, bending, reducing As long as it is operated according to this process, it is the correct operation. In addition, if there are errors in it, we also have to find a way to solve these errors. In the article, the editor will introduce these two aspects to you, come and see!

The technological process of hydraulic sheet metal bending machine:

1. Start the oil pump

The motor of the hydraulic sheet metal bending machine rotates in the direction indicated by the pump arrow, that is, rotates clockwise, which drives the axial plunger pump to run, and the oil enters the valve plate and the electromagnetic relief valve, and returns to the oil tank through the pipeline.

2. Downward movement

The rapid downward movement of the hydraulic sheet metal bending machine is produced by the dead weight of the bending beam and accessories and the oil pressure. In this process, the rodless cavity of the hydraulic cylinder is supplied with oil through the oil filling valve, the rodless cavity will generate back pressure, and the oil will flow back quickly.

3. Bending

The bending phase begins with pressure build-up in the rodless cavity. On the one hand, the bending speed is limited by the oil supply of the oil pump; on the other hand, it can be adjusted by the directional valve of the proportional valve. At the same time, the reversing valve also controls the synchronous operation of the curved beam and the positioning of the bottom dead center.

4. Decompression

The decompression of the rodless cavity begins when the bottom dead center is reached, or after a short hold time, so that the material has enough time to form and further improve the dimensional accuracy of the part.

5. Master cylinder return

The flow rate of the pump and the bearing area of ​​the cylinder rod cavity determine the return speed, which is close to the peak speed in most cases. The return stroke also needs to be synchronized, starting from the decompression of the rod cavity and ending at the top dead center.

The solution to the error of the hydraulic sheet metal bending machine:

1. It is necessary to check whether the mold of the hydraulic sheet metal bending machine is damaged. If the mold is worn, the work of the bending machine will definitely be affected. As long as the mold is trimmed, the problem can be solved.

2. If it is found that there is no problem with the mold, it is necessary to check whether the parallelism between the slider and the worktable of the hydraulic sheet metal bending machine meets the requirements. If there is any deviation, it needs to be readjusted.

3. If there is still an error after the above two steps, check the hydraulic system of the hydraulic sheet metal bending machine to see if the pressure oil enters the left and right cylinders evenly, if not, adjust it by yourself.

4. There are errors in the use of hydraulic sheet metal bending machines. It is impossible to say that there are no mistakes at all, and there is no need to be nervous when there are mistakes. If a problem is found, it can be solved with targeted adjustment or treatment.

In the article, the editor will give you a detailed introduction to the process flow of the hydraulic sheet metal bending machine and its error solution. Come and see it in the article!
