Powerful pressing method and apparatus for disk spring

Abstract

The invention discloses a powerful pressing method and apparatus of a disk spring. A disk spring assembly is formed through pairing of a plurality of disk springs and further comprises a guide bar, an upper pressing plate, a return spring and a pedestal, wherein the return spring is disposed in the pedestal, the guide bar penetrates the disk spring assembly and is disposed on the return spring, and the upper pressing plate is in fixed connection with the pedestal. According to the invention, the upper part of the guide bar penetrates the paired disk springs, the lower part of the guide bar is disposed on the return spring and in the pedestal, so the guide bar and the disk springs move downwardly together when the disk springs are powerfully pressed, and the guide bar is pushed to an initial position by the return spring during spring-back of the disk springs, thereby ensuring that the disk springs are fixed in the guide bar; thus, efficiency and safety of powerful pressing of the disk springs are improved, and critical values are obtained.

Description

technical field [0001] The invention relates to a spring pressing method and device, in particular to a disk spring pressing method and device. Background technique [0002] As a basic part of mechanical equipment, springs are used in many fields of modern industry, especially in the fields of machinery industry, railway industry, construction industry and nuclear power industry. There is also an increasing demand for Belleville spring units. Therefore, the quality requirements for the disc springs are very high, especially the pressing process of the disc springs is very important. In the prior art, when the disc springs are subjected to the pressing process, since there is no guide to fix the disc springs, it is easy to cause the disc springs along the diameter. In order to ensure safety, the number of disc springs should not be too many during the pressing process, but this will lead to low work efficiency and affect production efficiency.
