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.
