In real life and work, our mold workshop requires excellence in the design and production of various molds, and there will be problems in the specific operation, where we will discuss and exchange the problems in the use of stamping dies. The service life and springs of stamping die springs The selected load point is the size of the compression. The greater the deformation of the spring during work, the lower the life.
Often in practice, due to the limitation of the size of the mold structure, the spring cannot be installed in the best quantity and position, so Select the working load point near the limit of the spring, the stiffness of the spring increases instantaneously, Mould suppliers causing the early failure of the spring, and the service life of the spring is significantly reduced, and it is better to not reach the specified value of the spring standard.
The use of over-compression of the spring will make the spring Early failure. For example, in the field trial, due to the lack of unloading, pressing parts, etc., the springs of the same size and different specifications and models are temporarily replaced without considering the allowable compression of the replaced spring, which is the normal use of the spring in the future Cause hidden danger
