Requirements for stamping processing quality of stamping parts:

In the electronic stamping parts factory, the processing quality requirements for metal stamping parts are very strict. Therefore, we must strictly control the shape and size of stamping parts: first of all, the requirements for bending parts:

1) The shape of the bending piece should be as symmetrical as possible, and the bending radius should not be smaller than the minimum bending radius allowed by the material.

2) If the curved edge is too short, it is not easy to form, so the straight part of the curved edge should be H>2δ. If H is required to be very short, you need to leave an appropriate margin to increase H, and then cut off the added metal after bending.

3) When bending parts with holes, in order to avoid the deformation of the holes, the second is the requirement for deep drawing parts.

4) The shape of metal stamping parts should be simple and symmetrical, and the depth should not be too large. In order to minimize the number of deep drawing, easy to form.

5) The fillet radius of metal stamping parts does not increase the process procedure. Otherwise, the number of times of deep drawing and shaping work will be increased, the number of molds will also be increased, and waste products will easily be generated and costs will be increased.

     Whether the mold used for metal stamping parts uses a spring-pressed unloading plate or a fixed unloading plate depends on the size of the unloading force, and the material thickness is the main consideration. Along with the strengthening of the elastic force of the elastic element used in the mold (such as adopting a rectangular spring), the unloading force of pressing the unloading plate is greatly enhanced. According to the current situation, when the thickness of the material is less than 2mm, it is more practical to use a spring pressure stripper, and when it is greater than 2mm, it is more practical to use a fixed stripper. The thickness of the material punched by this mold is 1mm, so a spring-loaded unloading plate can be used. Metal stamping parts are formed by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of required shape and size.
