During the stamping process of the stamping terminal, the punch size may be too large or too small
1. When the knife edge of the stamping production workshop is damaged, the tensile strength of the stamping raw materials increases, and the milling and distortion of the stamping parts tend to increase.
2. The strong working pressure of the stamping parts causes the shape change of the raw material, which may lead to the increase of the stamping size. When the working pressure is reduced, the punch size will be reduced.
3. Shape of the end of the punch edge. If the top is a slope or arc, the punching root will be reduced, the punching parts are not easy to rotate and distort, so the punching size will be larger. When the top of the punch is neat, the size of the punch will be reduced.
