How important is the hardness of the plum blossom punch?

Some people say that the higher the hardness of the plum blossom punch, the better. Is this really the case? The answer is definitely no. Punch hardness is very important. This is true, but different molds have different hardnesses for punch punches. The right one is good. So how important is the hardness of the punch?

The hardness of the punch punch mainly affects the wear resistance of the punch. The higher the hardness, the smaller the wear and the better the wear resistance. However, the punch of a punch is often subjected to a large impact load, and if the hardness is too high, it is easy to cause fracture. In order to prevent the punch from breaking suddenly while working, the mold parts must have high strength and toughness.

The hardness of the punch punch needs to be selected according to the use situation, and it is particularly important to process it to the appropriate use hardness. Therefore, the punch material should have high anti-tempering stability to ensure that the punch has high hardness and strength at working temperature.

Don't think that the higher the hardness of the punch, the better, the result may be sudden fracture, which affects the production of the mold. So the appropriate punch hardness is very important.
