Analysis of the problem of unstable punching size for small stamping parts [hardware]

Small stamping parts often have a punching process, and stamping plants often encounter inconsistent punching sizes. What causes this problem and how to deal with it? Xiaoshuo understands with you: 1. When the punching edge is worn, the tensile stress on the material increases, and the tendency of 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 end of the punch blade. If the end is trimmed with a slope or arc, the punching force will be slowed down, and the punching part will not be easily turned or twisted. Therefore, 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. Hardware, 15 years of ingenuity focusing on small stamping parts, 20,000+ sets of mold customization production experience, monthly processing capacity of 100+ sets of molds, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, and 16 quality inspections. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
