Problems solved by technology

At present, most of the clutches of heavy-duty vehicles are used for overloading of the whole vehicle, so the reduction of the diaphragm spring load is required to be no more than 7%. The traditional manufacturing process is difficult to guarantee, and the stability of the diaphragm spring load of heavy-duty vehicle clutches is what we need Key issues to be solved

Abstract

The invention relates to a machining process for a diaphragm spring. The machining process comprises the following steps that a blank is made, specifically, a diaphragm spring raw material plate is provided and is cut to obtain a diaphragm spring blank; window punching is conducted, specifically, an even number of windows are punched once directly from the diaphragm spring blank obtained through blanking making through a punching machine; window grooves are punched, specifically, a window groove punching machine is used for punching the window grooves in the window-punched diaphragm spring blank, and an even number of window grooves are punched every time; window round corners are extruded, specifically, the window-groove-punched diaphragm spring blank is put on a window round corner die, all windows of the diaphragm spring blank are extruded simultaneously through the window round corner die, and the window round corners are completed; and heat treatment is conducted, specifically, heat treatment is conducted on the diaphragm spring blank obtained after the window round corners are extruded. The machining process has the beneficial effects that the window position degree is ensured well, the window round corners are extruded evenly, assembly of a clutch in the later period is convenient, the service life of the diaphragm spring is prolonged, and attenuation ratio of the diaphragm spring load is smaller than 7% compared with the load of an initial diaphragm spring.

Description

technical field [0001] The invention relates to the technical field of diaphragm spring processing, in particular to a diaphragm spring processing technology. Background technique [0002] The diaphragm spring is an important part of the clutch cover assembly. During the use of the clutch, it must not only be compressed (directly related to the load parameters of the diaphragm spring) to transmit sufficient torque and separate completely, but also to ensure separation. The fingertips are wear-resistant, and the diaphragm spring cannot be broken during the entire use process. More importantly, it is necessary to ensure smooth assembly of the clutch. [0003] The main process of diaphragm spring production: stamping, heat treatment (quenching, tempering, fingertip high-frequency quenching), shot blasting, strong pressing (including hot and cold strong pressing), load testing, surface oiling for rust prevention, packaging, transportation, etc. There are many links, and the rea...
