Background

The disc spring is also called a Belleville spring washer, is in a conical disc shape, can be used singly or in series or in parallel, bears static or dynamic loads acting along the axial direction at the upper inner edge and the lower outer edge, deforms after being compressed until being flattened, and is used as live load in the form of stored energy. When necessary, automatically converts into additional compression load required by sealing, so as to reduce the continuous requirement of tightening in the use of gaskets and packing.

Belleville springs are replacing cylindrical coil springs to a large extent. It is commonly used in heavy machinery (such as press) and weapons such as cannons and airplanes, as strong buffer and damping springs, as compression springs for automobile and tractor clutches and safety valves, and as energy storage elements for motorized equipment.

However, most of the existing disc springs are processed or produced manually, that is, a lower forming die is placed on a platform of a hydraulic press, an annular flat gasket is placed on a lower forming die with a guide post, an upper forming die is manually buckled on the annular flat gasket, and an annular semi-finished product is pressed into a disc spring semi-finished product with a certain taper in a manner of pressing down by the hydraulic press; firstly, the processing efficiency is low, the upper forming die needs to be manually taken down when each forming piece is formed, and the upper forming die is manually installed after the upper forming die is installed in the circular flat pad, so that the processing efficiency is low; the existing manual processing can affect the product quality, the lower forming die and the upper forming die are connected through the middle guide rod of the lower forming die, and a certain gap exists between the guide rod and the upper forming die, so that the upper forming die is difficult to center position when being manually placed at each time, the formed disc spring has quality problems of warping, poor consistency of free height and the like, and the final performance of the disc spring is affected.
