The working principle of cold heading machine is the casting forming method of roughening the top of bar or wire at room temperature. Cold heading is mainly used to manufacture bolts, nuts, nails, rivets, steel balls and other parts. The forging billet materials can be copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloy, and the utilization rate of materials can reach 80~90%. Cold upsetting is usually carried out by a dedicated cold upsetting machine leader, so that continuous, multi station and automatic production can be realized. On the cold upsetting machine, the processes of cutting, upsetting, accumulation, forming, chamfering, thread rolling, reducing and trimming can be completed in sequence. The production efficiency is high, reaching more than 300 pieces/minute, and the diameter of the largest cold heading workpiece is 48 mm.
