Background
In the mold industry, compression springs are the most common pressure-bearing parts, and the pressure load that can be borne by the compression springs is related to the stiffness and initial compression of the springs. The most common adjustment method at present is to change the initial compression amount of the spring by adding a gasket on the spring to adjust the initial pressure-bearing capacity of the spring. However, the adjusting mode is relatively complex, the original connection needs to be disassembled and then the gasket needs to be added for reassembly, and the adjusting process is complicated.
In addition, when the compression spring is unloaded after being deformed after bearing a certain load, the compression spring is restored to the position before being deformed, and self-locking cannot be realized. For the forming process with displacement limitation and step conversion, the traditional compression spring is not suitable any more, and a special hydraulic cylinder, an air cylinder and the like are needed to realize the forming process, so that the manufacturing cost and the control difficulty of the die are increased.
