secondly, in the spring hot working process, when steel is burned at high temperature, surface oxidation reaction can occur to form a layer of iron oxide covering, in the traditional spring hot working process, the influence of iron oxide on the spring working is usually ignored, but the covering can generally cause uneven surface of the spring, in the working process, the covering can be clamped between the spring and a roller, so that the spring cannot be wound by the roller, a large covering can deform the spring, a small covering can cause uneven surface of the spring to be pressed, and the size error and shape change can influence the service performance of the spring;
therefore, the invention provides a bracket for improving the machining precision of a spring, which overcomes and improves the defects in the prior art.
