Punching needle punch, the material determines the quality

    The punching pin punch is installed on the punching die to perform continuous punching and punching operations to separate or plastically deform the processed material, so as to obtain the required finished or semi-finished products. We often say that the material determines the quality, so how to choose the material of the punch?

    At present, the commonly used punch material is SKD11, which has the advantages of high hardness, wear resistance, good toughness, stable performance, and small heat treatment deformation. This material can also be nitrided. After nitriding and quenching, the hardness Around 60HRC, it is very suitable for punching dies, and it is a good material for punches.

     From the point of view of broken needles, the general reason is that the resistance during punching is too large, which exceeds the bearing capacity of the punch. At the beginning, check whether the mold is strained or deformed, and appropriately improve the inclination of the mold; if there is still no improvement, we need to start with the material of the punch, such as using better materials such as ASP, SKH-51, tungsten steel, etc. Material, and improve the heat treatment process.

    Material determines quality, which will never change during processing. Here, the editor of the punch punch reminds you that it is better to choose different materials according to different situations.
