Reputation will share the difference between cold heading and hot heading processing

Cold heading: It refers to the use of the plasticity of metals to apply pressure or cold draw using cold mechanics to achieve the goal of solid deformation of metals. A forging method of roughening the top of a bar or wire at room temperature. Yupu Cold Heading Machine is mainly used for manufacturing parts such as bolts, nuts, nails, rivets, and steel balls. Forging materials can be copper, aluminum, carbon steel, cold heading machine alloy steel, stainless steel, and titanium alloy, with a material utilization rate of 80-90%. Cold heading is often carried out on specialized cold heading machines, which enables continuous, multi-station, and automated production of multi-station automatic cold heading machines. On a cold heading machine, it is possible to sequentially complete processes such as cutting, heading, accumulation, forming, chamfering, wire rolling, diameter reduction, and edge cutting. High production efficiency, up to 300 pieces/minute or more, with a diameter of 48 millimeters for large cold heading workpieces. The schematic diagram of the cold heading bolt process is a typical process for cold heading bolts. The multi-station nut automatic cold heading machine is a multi-station nut automatic cold heading machine. The bar material is automatically fed into a certain length by the feeding mechanism, and the cutting mechanism cuts it into blanks. Then, the clamp conveying mechanism sequentially sends it to the accumulation pressing and punching stations for forming. Cold heading refers to the stamping of raw materials at room temperature.

Hot heading: refers to the stamping of raw materials after heating, with no specific requirements for specific purposes. Yupu Cold Pier Machining generally requires the use of cold heading because of the surface finish, the material's microstructure and composition will be relatively tight, and larger workpieces are often processed using hot heading.
