Whether the die used for metal stamping parts adopts the elastic unloading plate or the fixed unloading plate depends on the unloading force, and the material thickness is the main consideration. With the increase of the elastic force of the elastic element for the mold (such as the rectangular spring), the unloading force of the elastic unloading plate is greatly enhanced. Metal stamping parts are the forming and processing methods that apply external force to plates, strips, pipes and profiles by means of presses and molds to produce plastic deformation or separation, so as to obtain workpieces (stamping parts) of required shape and size.

If you want to extend the service life of the stamping parts, you need to maintain them regularly. Before installing the stamping parts, you should strictly check them, remove the dirt, check their lubrication performance, and regularly check the rotary table of the stamping parts! If there is wear at the edge of punch and die, we should stop using the product immediately, otherwise it will protect the wear degree of the edge and reduce the service life of the stamping. When installing the stamping, we should use soft metal tools to operate it to avoid damage to the stamping during installation, If we want to ensure the service life of stamping parts, we also need to replace the spring of the mold regularly to prevent the free-form damage from affecting the service life of stamping parts!

The processing of metal automobile stamping parts is the requirement for bending parts:

1. The shape of bending parts shall be symmetrical as much as possible, and the bending radius shall not be less than the allowable small bending radius of materials.

2. The curved edge is too short to be formed, so the straight part of the curved edge shall be H > 2 δ。 If h is required to be very short, appropriate allowance shall be reserved to increase h, and the added metal shall be cut after bending.

3. When bending parts with holes, in order to avoid the deformation of the holes, the metal stamping parts processing factory is next to the requirements for deep drawing parts.

4. The shape of metal stamping parts shall be simple and symmetrical, and the depth shall not be too large. So as to reduce the number of drawing and facilitate forming.

5. The fillet radius of metal stamping parts shall not increase the process procedure. Otherwise, the number of deep drawing and reshaping will be increased, the number of molds will be increased, and waste products will be easily generated and the cost will be increased.
