Stamped parts are one of the main products provided by our company. What are the common and specific problems to be solved in the production of stamped parts?

(1) When the cutting edge is worn, the tensile stress on the material increases, and the tendency of the stamped part to flip and twist increases. When flipping occurs, the punching size will decrease.

(2) The strong pressure on the material causes plastic deformation, which can lead to a larger punching size. When reducing strong pressure, the punching size will decrease.

(3) The shape of the end of the convex die blade. If the end is trimmed with an inclined or curved surface, the punching force slows down, making it difficult for the punched part to flip or twist, resulting in a larger punching size. When the end of the punch is flat (without inclined or curved surfaces), the punching size tends to decrease relatively.
