Description

Technical Field

[0001] The utility model relates to the field of spring manufacturing, in particular to a lathe winding machine. Background Art

[0002] The wire winding machine is a common mechanical processing equipment. Its main function is to curl metal wire into parts of various shapes, such as springs, chains, gears, etc. The product structure of the wire winding machine mainly includes wire introduction device, curling mechanism, discharging mechanism and transmission system.

[0003] The working principle of the winding machine is to use the elastic deformation of the wire and the friction between the slider and the guide rail to achieve curling. During the curling process, the wire is subjected to bending stress and tensile stress between the guide rail and the slider, which causes elastic deformation and gradually forms the desired shape. At the same time, the friction between the slider and the guide rail also plays a role in controlling the movement of the wire, so that the wire can be curled according to the specified trajectory.

[0004] In the prior art, hexagonal bars or round steels are usually required to limit and guide the wires. However, the diameter of the internal through holes of the existing hexagonal bars or round steels is fixed, which is not convenient for processing spring rods with different diameters.
