The stamping part is a forming method of applying a force to a plate, a strip, a pipe, a profile, and the like by a press and a mold to cause plastic deformation or separation to obtain a workpiece of a desired shape and size. Stamping and forging are plastic processing, collectively known as forging. The stamped blanks are mainly hot rolled and cold rolled steel sheets and strips.
There is a stamping die for a recessed aluminum part of an automobile
accessory, comprising a bottom plate, a top plate is arranged above the
bottom plate, a pressing plate is arranged on the top plate, a top plate
and a bottom plate are connected by a side plate, a pressing block is
arranged on the pressing plate, and a heavy object is stored in the
pressing block. The middle position of the top plate is provided with a
blanking groove, a pressing column is arranged below the pressing plate,
a punching head is arranged at the lower end of the pressing column, a
punching column is inserted in the blanking groove, and an upper driving
wheel and a lower driving wheel are arranged on the bottom plate.
There are many sheet metal materials suitable for stamping processing. Sheet metal materials widely used in the electrical and electronic industry include:
1. Ordinary cold-rolled steel sheet SPCC SPCC refers to continuous rolling of steel ingots into coils or sheets of a desired thickness through a cold rolling mill. SPCC surface without any protection, exposed to the air can easily be oxidized, especially in the humid environment, the oxidation speed, the emergence of dark red rust, the use of the surface to be sprayed, electroplated or other protection.
2. The substrate of galvanized steel sheet SECC SECC is a common cold-rolled steel coil. After the continuous galvanized steel production line is degreased, pickled, electroplated and various post-treatment processes, it becomes an electro-galvanized product. SECC not only has the mechanical properties and similar processability of ordinary cold rolled steel sheets, but also has superior corrosion resistance and decorative appearance. In the electronic products, home appliances and furniture market has great competitiveness and replaceability. For example, the computer chassis is commonly used SECC.
