Cangzhou Nanpi metal stamping parts, some common stamping problems + overall solutions for stamping parts

The production staff of the Cangzhou Nanpi hardware stamping parts processing plant once said that in the daily stamping production, they will encounter situations where the punching size is too large or too small (it may exceed the specification requirements) and the size of the punch is quite different. In addition to considering factors such as the design dimensions of the forming convex and concave dies, processing accuracy and blanking clearance, Xiaoshuo thinks that the following aspects should be considered to solve the problem: 1. When the punching edge is worn, the tensile stress on the material increases , 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 edge 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 focus on Cangzhou Nanpi metal stamping parts, 20,000+ sets of customized stamping die production experience, monthly 100+ sets of mold processing capacity, hundreds of precision processing production equipment, daily production capacity of 3 million punches, silk-like stamping accuracy Up to 0.01mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
