Punching problems in the processing of precision stamping parts?

In the processing of precision stamping parts, sometimes the punching size is too large or too small, and the size of the punch is quite different. 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. The strong pressure of stamping parts 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. The shape of the edge of the punch. If the end is trimmed with a bevel or arc, the punching part is not easy to turn over and twist due to the slowing of the punching force. Precision metal stamping can produce workpieces with reinforcing ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the precision of the workpiece can reach the micron level, and the repeatability is high, the specifications are consistent, and holes, bosses, etc. can be punched out. In the daily production of precision stamping parts, the size of the punching hole is too large or small (may exceed the specification requirements) and the size of the punch is greatly different, except for the design size and processing accuracy of the convex and concave molds. In addition to factors such as blanking clearance, the above aspects should also be considered. If you want to know more about precision stamping parts, or needs. Please add V: understand.
