[0002] Cold heading is a forging method that thickens the top of a bar or wire at room temperature. Cold heading is mainly used to manufacture parts such as bolts, nuts, nails, rivets and steel balls. The forging material can be copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloy. Cold heading is mostly carried out on a dedicated cold heading machine, which is convenient for continuous and automated production. A variety of processes can be performed on the cold heading machine, such as cutting, heading, accumulation, forming, chamfering, thread rolling, diameter reduction and trimming.

Each stamping is carried out through the buffer rod 4-6 and the shock-absorbing spring 4-7 at the bottom to reduce the shock and cooperate with the hydraulic buffer 4-4 to buffer and reset. The height of the processing table 3-2 can be controlled by the extension and retraction of the hydraulic cylinder 4-1. When replacing the processing table 3-2, the removable bolts can be lifted upward.
