Bending machine operation process and method to improve accuracy

by:WORLD     2022-08-26

With the improvement of economic benefits, the application of bending machine equipment is more and more common, and it can be made into a variety of workpiece requirements. Many manufacturers will not be as standardized as professional operations. What are the correct operation procedures of the equipment? So, how to improve its accuracy? Come and take a look with the world press machine.


Correct use of the process:

1. Strictly abide by the safety operation rules of machine tool workers, and wear labor protection equipment as required.

2. Before starting, it is necessary to carefully check whether the motor, switch, circuit and grounding are normal and firm, and check that the operating parts and buttons of the equipment are in the correct position.

3. Check the coincidence and firmness of the upper and lower molds; check whether each positioning device meets the requirements of being processed.

4. When the upper slide plate and each positioning axis are not at the origin, run the back-to-origin program.

5. After the equipment is started, it should run idly for 1-2 minutes, and the upper sliding plate will move 2-3 times in full stroke. If any abnormal sound or fault is found, it should be stopped immediately, and the fault should be eliminated, and it can work only after everything is normal.

6. When working, one person should be under the unified command, so that the operator and the feeding and pressing personnel are closely coordinated to ensure that all the cooperating personnel are in a safe position to send the bending signal.

7. When the sheet is bent, it must be compacted to prevent the sheet from lifting and hurting people during bending.

8. The power supply must be cut off when the plate material is pressed, and the operation must be stopped.

9. When changing the opening of the variable die, no material is allowed to come into contact with the die.

10. When the machine tool is working, no one is allowed to stand behind the machine tool.

11. It is strictly forbidden to fold the sheet at one end alone.

12. If the workpiece or mold is found to be incorrect during operation, it should be stopped for correction. It is strictly forbidden to correct by hand during operation to prevent hand injury.

13. It is forbidden to fold super-thick iron plates or quenched steel plates, alloy steels, square steels and plates that exceed the performance of the plate equipment, so as not to damage the machine tool.

14. Always check the coincidence of the upper and lower molds; whether the indication of the pressure gauge meets the regulations.

15. Immediately shut down when an abnormality occurs, check the cause and eliminate it in time.

16. Before shutting down, place a wooden block on the lower die under the oil cylinders on both sides and lower the upper sliding plate to the wooden block.

17. Exit the control system program first, and then cut off the power.

Ways to improve work accuracy:

In general, improving its working accuracy is only to improve the efficiency of our production better and more effectively to process our parts. In many cases its accuracy is only measured by static accuracy.


This is because the size of the mechanical strength of the press itself has a great influence on the stamping accuracy. The precision and strength of the press are closely related, and the size of the strength has a great impact on the stamping task. Therefore, in the blanking of high-precision workpieces and the production of cold stamping with strong continuity, high-precision, and Rigid press.

There should be consistent instructions for multiple people to operate the same equipment, and the machine should be carried out under the condition that the operation of the machine is stopped, and a pad should be placed under the slider for firm support. Before the official homework, the idling test must be carried out, and the work can only be performed after confirming that all parts are normal. Before starting the machine, all unnecessary items on the workbench should be cleared to avoid the sudden start of the slider caused by the vibration of the car and the injury of people or the impact of the switch.

The above introduction, I hope to help you understand the 'operation process of the bending machine and the method to improve the accuracy'.
