Flat washer mold manufacturers, why does the stamping mold have broken edges during processing?

In the production process of flat washer mold manufacturers, the phenomenon of broken edges of stamping molds often occurs. What caused this break? Xiaoshuo sorted out a few points, and let’s take a look with you: 1. When rubber is used as an elastic unloading part, due to improper assembly, in the process of flat washer, the rubber compresses and expands laterally and squeezes the punch to one side. 2. The unbalanced spring force in the unloading device causes the unloading plate to tilt, so that the punch is pushed by the lateral force to bend and break. 3. The large and small punches are close to each other. In the process of punching, the material around the large hole is deformed to produce a side extrusion force on the small punch, which may cause the small punch to break. 4. Knife edge breakage is often due to incorrect design and manufacturing. The corner radius of the stepped punch is small, the rough machining does not allow edge marks and grinding cracks, and the machining does not completely remove the decarburized layer caused by forging and The failure to change the carbide segregation during forging of high-alloy tool steel, improper execution of heat treatment process, etc. can cause early breakage of the punch. Especially for cold extrusion punches.
