A punch is a punch. In national production, stamping technology has been more and more widely used because of its advantages of saving materials and energy, high efficiency, low technical requirements for operators and products that cannot be machined through various molds.

Stamping production is mainly aimed at sheet metal. Blanking, punching, forming, stretching, trimming, fine punching, shaping, riveting and extruding parts can be made through the die, which is widely used in various fields. For example, we use switch sockets, cups, cabinets, plates, computer cases, and even missile planes ... there are many accessories that can be produced by punching machines through molds.

Because the punch has the characteristics of high speed and high pressure, certain safety regulations must be observed when punching and forming with the punch.

1. The transmission parts exposed to the outside of the press must have a protective cover, and it is forbidden to start or test run with the protective cover removed.

2. Before driving, check whether the main fastening screws are loose, whether the mold is cracked, whether the control mechanism, automatic stop device, clutch and brake are normal, and whether the lubrication system is blocked or short of oil. If necessary, you can drive an empty car for testing.

3. When installing the mold, the slider must be opened to the bottom dead center, and the closing height must be correct to avoid eccentric load as much as possible; The mould must be firmly fixed and checked by pressure test.

4. Pay attention when working. It is forbidden to put objects such as hands and tools into the danger zone. Small parts must be operated with special tools (tweezers or feeding mechanism). When the mold is stuck in the blank, only tools are allowed to release it.

5. In case of abnormal operation or abnormal sound (such as combo sound and crackle sound) from the printing press, stop feeding immediately and check the reasons. If the rotating parts are loose, the control device fails, the mold is loose and defective, the machine should be stopped for repair.

6. When cleaning each workpiece, hands or feet must leave the button or pedal to prevent misoperation.

7. When two or more people operate, they should drive by themselves and pay attention to coordination. Before coming off work, close the mold, turn off the power and clean it as necessary.
