The specific operation process is to put the metal bar into a cold heading machine and squeeze it into shape through pressure. During the extrusion process, the metal bar will undergo plastic deformation, thereby changing its shape and size, and the head of the fastener will also be formed.
In the field of fastener manufacturing, cold heading technology is widely used because it has the following characteristics:
- Cold heading process can be carried out at room temperature without heating metal materials;
- Cold heading technology can reduce or replace cutting processing, improving material utilization rate;
- The models and series of cold heading machines are complete, suitable for forming various bolts and nuts, with reliable equipment performance, high efficiency, and stable quality;
- Cold heading machines can achieve continuous, multi-station, automated production, simple operation, and are suitable for mass production;
- Cold heading process can improve the surface smoothness of the workpiece and ensure the accuracy of the workpiece, and can manufacture high-precision and high-strength bolts, nuts, etc;
- The cold heading process can improve the mechanical properties of the workpiece, such as increasing the density and hardness of the material, thereby enhancing wear and corrosion resistance.
Cold heading technology can improve productivity, ensure fastener quality, reduce material loss, and reduce production costs, and is increasingly widely used in the production of standard fasteners.
