         The forging method of thickening the top of bar or wire at room temperature. Cold heading machines are mainly used to manufacture parts such as bolts, nuts, nails, rivets, and steel balls. The forging billet material can be copper, aluminum, carbon steel, alloy steel, stainless steel, titanium alloy, etc., and the material utilization rate can reach 80-90%. Cold heading is often carried out on specialized cold heading machines, which facilitates continuous, multi station, and automated production. The cold heading machine can sequentially complete processes such as cutting, heading, accumulation, forming, chamfering, wire rolling, diameter reduction, and edge cutting. High production efficiency, reaching over 300 pieces per minute, with a maximum diameter of 48 millimeters for 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, cut into blanks by the cutting mechanism, and then sequentially sent to the accumulation and punching stations for forming by the clamp conveying mechanism.
