In actual work, the compression spring should be able to maintain its working length even if it is subjected to a force beyond the elastic limit of the material. Therefore, the length of the finished spring should be equal to the calculated length of the spring plus the initial compression, which can prevent the spring from being out of place, so as to avoid dangerous stress when the coil is tightened, which may cause the spring indicator line to be abnormal and not in place. In the heat treatment process of the finished spring, especially the hardening and tempering process, the workpiece must be placed horizontally (horizontally) in the furnace to prevent the spring from being shortened due to its own weight and the operation is not in place.
