What characteristics do steel wire crusher blades need

The steel wire crusher blade is similar to the plastic crusher blade. It uses a fixed knife and a moving knife. Unlike the plastic blade, the steel wire crusher blade is broken by the biting force between the moving knife and the fixed knife. It is a form of tearing. There are no too many requirements for the sharpness of the blade edge, but it is not easy to use if it is too sharp.

There are two opinions in the industry about the characteristics required for the selection of steel wire crusher blades. One is to choose carbon steel with good toughness, because the things to be crushed are all kinds of metal shells, and poor toughness is very likely to cause blade cracking. Another theory is to choose cold working die steel with high wear resistance, such as steel similar to SKD11, because if the wear resistance of the crusher blade cannot be guaranteed, the metal of the crusher will cause great damage to the tool, and the tool should be changed very frequently.

The technology department believes that selecting carbon steel or die steel is going to two extremes. The steel wire crusher blade is different from the plastic blade. If a relatively balanced material can be found in toughness and wear resistance, 6CrW2Si is selected, with a heat treatment hardness of about 55 ° and good toughness, which is suitable to be used as a tool for crushing steel wire.
