The invention relates to a process for continuously reducing the load attenuation rate of a diaphragm spring. The process comprises the following steps of 1, producing a raw material plate into a diaphragm spring blank material; 2, conducting direct one-time punching on the diaphragm spring blank material through a window punching machine, so that an even number of windows are obtained; 3, conducting window groove punching on the windows in the diaphragm spring through a window groove punching machine; 4, conducting extruding on the windows in the diaphragm spring through a window fillet mold,so that fillets of the windows are produced; 5, conducting stamping machining on the diaphragm spring to obtain five bolt round holes; 6, removing a separated finger on the diaphragm spring, so thata first radial notch is formed; and 7, conducting heat treatment on the diaphragm spring. The process has the beneficial effects that assembling, at the later stage, of a clutch can be conducted conveniently; the service life is effectively prolonged; and the state formed through heating reinforcing is in an inverted-cone shape, so that when the load of the reinforced diaphragm spring is comparedwith the load of an initial diaphragm spring, the attenuation rate meets the production requirement.
