Because the punch has the characteristics of fast speed and high pressure, the use of punch for punching and forming must comply with certain safety regulations.
1. Transmission parts exposed to the outside of the press must be equipped with a protective cover, and it is forbidden to drive or test run with the protective cover removed.
2. Before starting, 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 lack of oil. If necessary, you can drive an empty car for testing.
3. The installation mold must open the slider to the bottom dead center, and the closing height must be correct, so as to avoid eccentric load as much as possible; The mold must be fastened firmly and checked by pressure test.
4. Pay attention at work, and it is strictly forbidden to put hands and tools and other objects into the danger zone. Small pieces must be handled with special tools (tweezers or feeding mechanisms). When the mold is stuck in the blank, only tools are allowed to free it.
5. If it is found that the press is running abnormally or there is an abnormal sound, (such as a continuous hitting sound or a popping sound), the feeding should be stopped immediately and the cause should be checked. If the rotating parts are loose, the control device is out of order, the mold is loose and defective, it should be stopped for repair.
6. When each workpiece is punched, the hands or feet must leave the button or pedal to prevent misoperation.
7. When more than two people operate, someone should be assigned to drive, and attention should be paid to good coordination. Before leaving work, the mold should be dropped, the power supply should be disconnected, and the necessary cleaning should be carried out.
