Description

A torsion shear type bolt cold heading machine

Technical Field

The utility model relates to the technical field of bolt production, and in particular to a torsion shear type bolt cold heading machine.

Background Art

Cold heading machine is a kind of stamping machine in mechanical manufacturing. The steel used to make fasteners and connectors by cold heading is called cold heading steel, commonly known as rivet steel. Cold heading is the process of forming metal plasticity at room temperature. The use of cold heading technology to make fasteners is not only efficient and of good quality, but also saves materials and has low cost.

During the production process of torsion shear bolts, operators often use corresponding cold heading machines to perform cold heading operations on cold heading steel. In actual use, although the existing cold heading machines have basic cold heading functions, when raw materials are added to the general cold heading machines, due to the large inertia of the raw materials falling, there will be a deviation between the landing point of the material and the mold. At this time, the operator usually manually puts the raw materials directly above the mold, which not only reduces the efficiency of the cold heading operation of the device, but also increases the labor intensity of the operator and the possibility of injury during positioning due to manual positioning. Therefore, it needs to be improved.
