In daily production, stamping parts will encounter situations where the punching size is too large or too small (may exceed the specification requirements) and the size of the punch is large. In addition to considering the design size, processing accuracy and processing accuracy of the forming convex and concave mold In addition to the blanking gap and other factors, the following considerations should also be taken into consideration. Follow the editor of CISCO Stamping Part to get a simple understanding!


1. When the punching edge is worn, the tensile stress on the material increases, and the tendency of the stamping parts to turn over and twist increases. When turning over, the size of the punching hole will become smaller.
2. The strong pressure on the material causes plastic deformation of the material, which will cause the punching size to become larger. When the strong pressure is reduced, the punching size will become smaller.
3. The shape of the edge of the punch edge. If the end is trimmed with a bevel or arc, the punching force is not easy to turn over and twist due to the slowing of the punching force, so the punching size will become larger. When the end of the punch is flat (no bevel or arc), the punching size will be relatively small.
To sum up, the editor of CISCO Stamping Part tells about the handling of common problems in the production of stamping parts.
