Description

TECHNICAL FIELD

[0001] The utility model relates to torsion spring assembly field especially relates to a spring ring torsion spring's automatic assembly mechanism. BACKGROUND

[0002] Torsion spring is one of the widely used springs, and it generates elastic force through torsional deformation. Its working part is surrounded by coils closely or separately, and the end structure is processed into various shaped torsion arms from single torsion to double torsion, or even various torsion rod deformations, which can be shaped according to the design. The bottom of the torsion spring is often fixed in other places. When other components rotate around the spring center, the spring will quickly pull the other components back to the original position to form a rotating force, and the generated rotating force will be converted into the required resistance. In this way, the torsion spring can store and release angular energy, or fix a device in a static way by rotating the force arm around the spring body axis.

[0003] When the torsion spring is processed, an automatic assembly mechanism needs to be used. The existing automatic assembly mechanism, when in use, transports the fine wire between the multiple extrusion knife heads through the discharging device at the center of the mounting seat. The multiple extrusion knife heads have different functions, such as bending, rolling, and cutting. However, when not in use, the multiple knife heads are directly exposed to the outside, which may pose a safety hazard to the operator, especially during machine maintenance, debugging, or cleaning. Accidental cuts or stings may occur, and the exposed knife heads may be accidentally touched in the non-working state, causing unnecessary actions, which may damage the equipment and other components.
