Description

Technical Field

[0001] The utility model relates to the technical field of disc spring processing, in particular to disc spring processing flat grinding equipment. Background Art

[0002] Disc springs, also known as Belleville spring washers, were invented by the Frenchman Belleville. They are conical discs and can be used individually or in series or in parallel. They bear static or dynamic loads acting in the axial direction at the upper inner edge and the lower outer edge. They are deformed after being compressed until they are flattened, storing energy as live loads. When necessary, they are automatically converted into additional compression loads required for sealing to reduce the continuous tightening requirements of gaskets and packings during use. Disc springs are special springs that are conical in the axial direction and bear loads. After being deformed under load, they store a certain amount of potential energy. When the bolts become loose, the disc springs release part of the potential energy to keep the pressure between the flange connections to meet the sealing requirements. The stress distribution of disc spring decreases evenly from the inside to the outside, which can achieve the effect of low stroke and high compensation force. During the processing of disc spring, the disc spring is often ground and smoothed to remove burrs. When grinding the disc spring, since the disc spring is in the shape of a slightly raised disc, the diameters of the outer edge and the inner edge are different, and the position needs to be constantly adjusted when grinding the disc spring. At the same time, since the disc spring needs to be comprehensively ground, the disc spring needs to be removed and turned over when grinding different surfaces of the disc spring. The grinding of the disc spring cannot be completed in one go, resulting in a decrease in the grinding efficiency of the disc spring. For this reason, we proposed a disc spring processing and grinding equipment. Utility Model Content
