[0002] Cold heading machine is a kind of stamping processing machine in mechanical manufacturing. It forms the material into the required shape without making any changes to the raw materials (mainly softening or hardening and other similar treatments). For example, fasteners and connectors (such as bolts, nuts, screws, rivets, etc.) are manufactured by cold heading processing. The steel used is called cold heading steel, commonly known as rivet steel. Cold heading is the process of forming metal plasticity at room temperature. The cold heading process is used to manufacture fasteners. It is not only efficient and of good quality, but also saves materials and has low cost. The material used in the cold heading machine is usually wire, which is usually in a coiled structure. The coiled wire is sleeved on a shaft for escort.

[0003] At present, the existing cold heading machines still have some defects when used. It is often inconvenient to demould and collect the processed materials, and they need to be taken out manually, which increases the workload and reduces the work efficiency. For this reason, we propose an improved cold heading machine. Utility Model Content
