The service life of the selected spring of the single-spring design load point has a great relationship with the load point selected by the spring, that is, the amount of compression. The larger the deformation of the spring during operation, the lower the life. However, in actual use, due to the limitation of the size of the mold structure, the spring can not be installed with the optimal number and position. The work load point is selected near the limit value of the spring, and the stiffness of the spring is instantaneously increased, resulting in early failure of the spring. The service life is significantly reduced and the maximum service life of the spring cannot be achieved.

The amount of compression of the spring should be selected in the vicinity of the spring standard "specified value". Determination of the diameter of the spring mounting socket and the diameter of the mandrel The selection of the diameter of the spring mounting socket and the mandrel is essential for the normal use of the spring. The diameter of the socket and the mandrel should be selected to a reasonable value to stabilize and guide the spring. Also, to prevent excessive restraint of the spring. The spring standard only gives the minimum diameter of the socket and the maximum diameter of the mandrel. Each mold manufacturer can set the diameter size according to the actual design, processing and assembly.

When the mandrel and the socket are used together, the deviation caused by the manufacturing and assembly causes the mandrel to deviate from the center of the socket to cause the spring to bend and break, and the constraint on one end of the spring needs to be appropriately relaxed. The length of the guide length refers to the length of the spring mandrel and the depth of the socket. The length of the guide is insufficient. When the spring is stressed, the side bends or tilts easily, causing the spring to rub against the socket or the mandrel and causing the spring. Early failure.
