The punch press, that is, the stamping die press, has the advantages of saving raw materials and energy, high efficiency, low technical requirements for the operator, and being able to make products that can not be achieved by mechanical processing according to the use of various dies. Its main uses are also relatively more and more common. Next, we will introduce the common problems in the safe operation of punch press

Because the punch has the characteristics of faster speed and high pressure, it is necessary to abide by certain safety regulations when selecting punch for blanking and forming.

1. Before driving the punch, check whether the key fastening screws are loose, whether the mold is cracked, whether the control organization, automatic termination device, clutch and brake are normal, and whether the lubrication system is blocked or oil is low.

2. The punch press can be operated empty when necessary. The transmission parts exposed outside the press must be installed with protective cover. It is forbidden to drive or test run with the protective cover removed.

3. When installing the common punch die, the slider must be adjusted to the bottom dead center, the closing height must be appropriate, and the axial force load must be avoided as far as possible; the die of the punch must be firmly fastened, and it must go through the pressure test.

4. Pay attention to work, do not put your hands and tools into the dangerous area. Large parts must be operated with special tools (tweezers or feeding organization). Only tools can be used to get rid of die block.

5. In case of abnormal operation or abnormal sound of punch (such as continuous cutting sound and burst sound), stop feeding and check the cause. If the rotating parts are loose, the control device is invalid, and the mold is loose or damaged, it should be stopped for maintenance.

6. When punching a workpiece, the hand or foot must leave the key or pedal to avoid misoperation.

7. When two people are working on it, they should drive by themselves and pay attention to harmonious cooperation. Before off duty, the mold should be left, the power supply should be cut off, and the necessary cleaning should be carried out.

8. Punch engineering must go through the study and training, grasp the structure and characteristics of the equipment, understand the operation technical specifications and obtain the operation approval to operate independently.

9. The safety maintenance and control devices on the equipment should be properly applied and should not be removed at will.

10. Check the transmission, connection, moistening and other positions of the machine tool and whether the protective safety device is normal. The screw for installing the mold must be firm and cannot be moved.

11. The machine tool needs to be idle for 2-3 minutes before operation. Check the flexibility of foot brake and other control devices. It can only be used after it is confirmed that it is normal. It can not be operated with diseases.

12. Make sure that the machine tool is in good working condition and the key parts of the die are in good condition.

13. Before driving, pay attention to moistening and take out all floating objects on the bed surface.

14. The operator should stand up properly, keep a certain distance between the hand and the top of the head and the punch, pay attention to the position of the punch needle at all times, and do not chat with others.

15. When punching or making short workpieces, special tools should be used. It is not allowed to feed or pick up the workpieces immediately.

16. When punching or manufacturing long body parts, no safety support or other safety measures shall be taken to prevent excavation injury.

17. It is forbidden to put the hands and feet on the hand and foot brake when single flushing, and it is necessary to move (step) once to prevent safety accidents.

18. When two people operate on each other, the person who is responsible for moving (stepping) the gate must pay attention to the posture of the feeder. It is forbidden to move (stepping) the gate while picking up the parts.

19. When the work is finished, stop immediately, cut off the power supply, wipe the machine tool and comb the environment.
