Common problems in the processing of metal stamping parts

1. In the daily processing of Metal Stamping parts, the punching size is too large or small, and the size of the punch is quite different.

2. When the punching edge is worn, the tensile stress on the material increases, and the tendency of metal stamping parts to turn over and twist increases. When turning over, the size of the punching hole will become smaller.

3, the strong pressure of the metal stamping parts processing on the material will cause the material to produce plastic deformation, which will cause the punching size to become larger. When the strong pressure is reduced, the punching size will become smaller.

4, the shape of the end of the punch blade. If the end is trimmed with a bevel or arc, due to the slowing of the punching force, the punching part is not easy to turn over and twist.
