Winding method of mechanical spring

There is a slight difference between mechanical spring and conventional spring, that is, the spring itself is irregular, with bending and a large number of complex angle design. During the production of mechanical spring, its winding methods mainly include cold winding method and hot winding method. The following is a detailed introduction of the winding method of Mechanical spring by the full standard mechanical spring factory

1、 Cold winding method: the diameter of spring wire D ≤ 8mm is wound by cold winding method. The machine element spring in cold state is usually cold drawn and pre heat-treated high-quality carbon spring steel wire. After winding, the medium temperature spring steel wire is not quenched, and only needs low temperature tempering to eliminate the internal stress during winding

2、 Hot rolling method: the machine element spring with larger diameter (d > 8mm) is wound by hot rolling method. The machine element spring rolled in hot state must be quenched after winding

Mechanical spring manufacturing and processing technology is also relatively demanding, equipment is also relatively demanding, generally the computer machine winding, because the winding angle, bending more, so the production speed is slow, because of its complexity, mechanical spring production and processing can often represent a company's technical level
