It is mainly applied to important parts, which can effectively solve the effect of impact load on the spring with a long service life.
The invention relates to a method for winding a plurality of strands of spring, which is characterized in that the utility model is characterized in that the steel rope is twisted and twisted around the spring, and the other one is that the steel rope is twisted and the winding spring is carried out step by step, namely: first, the steel wire is twisted, and then the coil is wound by the coil spring. The utility model can be used for twisting the steel rope and winding on the lathe, and can also be used for winding the machine tool with the automatic twisting rope mechanism at the same time.
The typical process may refer to the following:
Filling, (Ning Gangsheng), winding, cutting, grinding head, appearance inspection, surface treatment (depending on the product requirements and whether the welding, welding) at both ends (as needed), filing head (as needed), and end ring (head), correction, thermal treatment, compression, correction, repair (as the end ring need to) inspection and surface treatment (surface treatment has no such procedure, oil)
