Now cold heading machines are common in the market, mainly because they have many advantages. They not only have preferential prices and stable forming standards, but also have a variety of processing varieties, and their role can not be underestimated. Cold heading machine is a special machine tool for manufacturing various standard parts such as screws and rivets by cold heading. It is formed in the form of a whole die. It is suitable for industrial manufacturers who produce screws and rivets in batch. The whole structure of the cold heading machine is carried out automatically from straightening, material selection, cutting, secondary forming to blanking. So how does the cold heading machine work?

A forging method for roughening the top of a bar or wire at room temperature. Cold heading is mainly used to manufacture bolts, nuts, nails, rivets, steel balls and other parts. Forging blank materials can be copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloy, and the material utilization rate can reach 80 ~ 90%. Cold heading is mostly carried out on a special cold heading machine, which is convenient to realize continuous, multi station and automatic production. The cold upsetting machine can sequentially complete the processes of cutting, upsetting, accumulation, forming, chamfering, thread rolling, diameter reduction and edge cutting. The production efficiency is high, up to more than 300 pieces / min, and the diameter of the maximum cold heading workpiece is 48 mm. The bar is automatically fed into a certain length by the feeding mechanism, cut into blank by the cutting mechanism, and then sent to the accumulation forming and punching station by the clamp transmission mechanism for forming.
