Problems solved by technology

At present, the diaphragm springs used in the industry, such as the diaphragm springs used in DS330 series diaphragm spring clutches, are usually produced by blanking 50CrVA hot-rolled plates → turning the outer circle → punching the window and groove → grinding → pressing the window circle Corner→External fillet→Punching hole→Heat treatment and other processes are produced. The process is relatively cumbersome and the production efficiency is low; while the product precision can be controlled at a disc angle of 14°, and the fingertip beating is within 1mm, the precision is even higher. It is more difficult to achieve, the product qualification rate will be greatly reduced, and the fatigue life will be shortened

Embodiment Construction

[0012] The improvement of the manufacturing process of the diaphragm spring of the present invention comprises the following steps:

[0013] 1) Raw material blanking, that is, the blanking material is punched out of the outer circle shape of the diaphragm spring on the punching machine, and the raw material is 50CrV4 precision cold-rolled plate;

[0014] 2) One-time punching of the window and groove, that is, simultaneously punching out the window and forming the groove of the separating finger on the punching machine;

[0015] 3) One-time pressing of window rounded corners and outer rounded corners: directly press out window rounded corners and outer rounded corners at one time through the window rounded corners and outer rounded corner molds on the press;

[0016] 4) Punch the hole;

[0017] 5) heat treatment.

Abstract

The invention discloses a manufacture process improvement of diaphragm springs, comprising the following steps: 1) blanking raw materials: namely, punching the blanking into an excircle shape of a diaphragm spring on a punch; 2) punching a window and a groove at once, namely, punching the window and the groove which forms a separated finger on the punch at the same time; 3) pressing a window fillet and an excircle fillet, namely, pressing the window fillet and the excircle fillet by a mould of the window fillet and the excircle fillet on the punch at once; 4) punching a mesopore; and 5) carrying out heat processing. The invention can improve manufacturing efficiency of diaphragm springs, reduce accumulated error of multiple working procedures, and improve dimensional accuracy of products.

Description

technical field [0001] The invention relates to a manufacturing process of a diaphragm spring. Background technique [0002] Diaphragm spring is the most critical part of the automobile diaphragm clutch, which plays the role of generating pressure on the pressure plate, cutting off power, and overload protection; the performance and life of the diaphragm spring determine the performance and life of the clutch. service life. At present, the diaphragm springs used in the industry, such as the diaphragm springs used in DS330 series diaphragm spring clutches, are usually produced by blanking 50CrVA hot-rolled plates → turning the outer circle → punching the window and groove → grinding → pressing the window circle Corner→External fillet→Punching hole→Heat treatment and other processes are produced. The process is relatively cumbersome and the production efficiency is low; while the product precision can be controlled at a disc angle of 14°, and the fingertip beating is within 1...
