Common problems of stamping dies in the stamping process

In the stamping process, various problems often occur in the work of stamping dies, which affect the quality and production efficiency of precision stamping parts. Stamping parts manufacturers need to analyze the root causes of the problems in order to effectively solve them. Let's take you to know 3 common problems in stamping die work. 1. Die wear The knife-edge wear that we often say in the stamping industry is a manifestation of die wear. During the stamping process, the friction between the upper and lower dies and the materials is inevitably abraded. When the abrasion condition is severe, the processed stamping parts will produce larger burrs, resulting in unqualified products. However, the wear of the mold can generally be solved by grinding. 2. The mold is deformed. When the mold is deformed, the shape of the processed precision stamping parts will also be deformed, so that the size of the product produced cannot meet the requirements. The deformation of the stamping die is mainly caused by improper material selection or improper heat treatment. The force of the die during the stamping process causes deformation. 3. Knife-edge gnawing In the process of assembling the stamping die, if the die and punch are not properly matched, or the gap design is unreasonable, it is easy to cause the die-edge gnawing during stamping. If the gnawing injury is not serious, it can be solved by grinding. If the gnawing injury is serious, just remake it. The above are the common problems in stamping die processing.
