Stamping part is a kind of forming processing method which uses press and die to exert external force on sheet, strip, pipe and profile to produce plastic deformation or separation, so as to obtain the required shape and size of workpiece (stamping part). Rongzhi automobile stamping parts show that stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The billets for stamping are mainly hot-rolled and cold-rolled steel plates and strips.

1. The semi-automatic and manual punch must be equipped with two hand brake switch. It is forbidden to press with foot or one hand start switch.

2. After the high punch is adjusted and the machine is stamped normally, close the sound isolating box (except for the packaging of product 8065 at the border inspection).

3. During continuous stamping, employees cannot take products by hand within 1m of the punch.

4. When the technician is on the mold for debugging, only one person can debug, not two people.

5. The technician can only transfer materials outside the machine and the distance is not less than 1m.

6. When erecting the die, it is necessary to lock the screws and stop the machine for 4 hours to check whether the screws are loose.

7. When the mold has problems in the production process and does not need to be unloaded, it is necessary to turn off the power supply of the injection molding machine and hang the maintenance sign on the power box before the mold can be repaired.

A large number of cold stamping processes have been used in the production of automotive stamping parts, which are suitable for the needs of many varieties and large-scale production of automotive stamping parts industry. In medium and heavy-duty vehicles, most of the covering parts, such as body outer panel, and some load-bearing and supporting parts, such as frame, carriage and other auto parts are automobile stamping parts. Automobile stamping parts indicate that the steel used for cold stamping is mainly steel plate and steel strip, accounting for 72.6% of the steel consumption of the whole vehicle. The relationship between cold stamping materials and automobile stamping parts production is very close. The quality of materials not only determines the performance of products, but also directly affects the process design of automobile stamping parts process, product quality, cost, service life and production organization Material selection is an important and complex work.
