Precision stamping parts design process

The design process of precision stamping parts is:
Reasonable mold design. In the stamping die, the arrangement of the blanking sequence may affect the precision of the forming of the stamping. For the blanking of the small parts of the stamping parts, generally, a large area of punching and cutting is arranged, and then a small area of punching and cutting is arranged to reduce the influence of the punching force on the forming of the stamping parts.

Add a strong pressure function. That is, the size of the unloading insert pressing portion is increased to increase the pressure on the material of the concave mold side, thereby suppressing the turning and twisting deformation of the stamping part during the punching.
The end of the punch edge is trimmed or curved. This is an effective way to reduce the buffering power. By reducing the cushioning force, the tensile force on the material of the concave mold side can be alleviated, thereby suppressing the effect of turning and twisting the stamping part.

In the daily mold production, attention should be paid to maintaining the sharpness of the punching and concave die edges. When the cutting edge is worn, the tensile stress of the material will increase, and the tendency of the precision metal stamping parts to turn and twist will increase.
