What are the effects of unreasonable mold gaps on stamping parts

The die gap of stamping parts is related to the type and thickness of the material being stamped. Unreasonable gaps can cause the following problems: 1. If the die gap is too large, the burrs of the stamping parts produced will be relatively large and the stamping quality will be poor. If the gap is too small, although the punching quality is better, the mold wear is more serious, and the service life of the stamping die is greatly reduced, and it is easy to cause the punch to break; 2. If the gap is too large or too small, it will be easy Adhesion occurs on the punch material, resulting in material stripping during stamping. A small gap is likely to form a vacuum between the bottom surface of the punch and the sheet material, which will cause scrap to rebound; 3. A reasonable gap can extend the life of the stamping die and unload the material. Good effect, reduce burrs and flanging, keep the plate clean, the hole diameter will not scratch the plate, reduce the number of sharpening, ensure the straightness of the plate, accurate punching positioning, etc.; Recommended article: Inspection method for welding quality of automotive stamping parts What is it?
