During the cold heading process of standard parts, the cemented carbide cold heading die has to withstand large impact forces. In order to meet the usage requirements, it is necessary to choose cemented carbide with high cobalt content, high strength and good impact toughness.
Tungsten carbide cold heading molds are used for fastener screws, bolts and rivets. Carbide molds have high hardness and can withstand high pressure and stress.
1. Cold heading is carried out under normal temperature conditions. Cold heading can improve the mechanical properties of metal parts.
2. Cold heading forging process can improve material yield. It is a pressure processing method based on plastic deformation, which can achieve less or no cutting processing. Generally, the material utilization rate is above 85%, and can reach as high as above 99%.
3． Can improve production efficiency. The time and process of deforming metal products are relatively short, especially when parts are processed on multi-station forming machines...
4. The cold heading and forging process can improve the surface roughness of the product and ensure product accuracy.
