Technical Field

[0001] The utility model relates to the technical field of positioning and pressing for torsion spring winding, in particular to a positioning and pressing device for torsion spring winding. Background Art

[0002] Torsion spring, also known as torsion spring, is a mechanical part that uses elasticity to work. It is generally made of spring steel and is used to control the movement of mechanical parts, alleviate impact or vibration, store energy, measure the size of force, etc. When processing torsion springs, a device is required to play a role in positioning and pressurizing during the torsion spring winding process.

[0003] When the head of the strong pressure device contacts the torsion spring steel, it is easy to wear. After long-term use, the worn strong pressure device may cause the torsion spring to shake when winding, which may cause the torsion spring to be crooked or the surface of the torsion spring to be scratched by the wear. Therefore, a strong pressure device that can be easily replaced and reduce wear is needed.

[0004] For this purpose, we propose a positioning and strong pressure device for torsion spring winding. Utility Model Content
