What is the reason for the broken punch in the mold use of the stamping factory-hardware

Stamping factories often encounter stamping fractures. Punches are distinguished according to the probability of fracture, followed by pre-punch and special-shaped punch with weak structure. And these two kinds of punches are generally broken at the working part. In addition, the special-shaped punch of the cutting material is often broken because of the convex part of the punch, and it is also common. The following Xiaoshuo will communicate with you about some of the reasons that cause these punches to break. 1>. The concave die is blocked due to insufficient blanking slope or too large magnetism of the concave die, so that the punch is broken. 2>. The working part is too long and the strength is not enough. 3>. The gap between the punch and the die is offset 4>. At the next time, the material is stuck in place (or there is a foreign body in the mold cavity) 5>. The amount of stroke has reached normal damage 6>. The spring in the stripper plate is broken, causing the stripper plate to deform and break 7>.
