Continuous punching method of diaphragm spring

The invention discloses a continuous punching method of a diaphragm spring. The continuous punching method of the diaphragm spring comprises the following steps: a: providing a diaphragm spring continuously punching die capable of punching slots, punching holes, pressing square-hole round corners, dropping half materials and pressing outer round corners; b: placing a raw material on the diaphragm spring continuously punching die and punching a slot and a square hole in the raw material on the diaphragm spring continuously punching die; c: pressing the square hole round corner on the raw material treated in the step b on the diaphragm spring continuously punching die; d: punching a central hole in the raw material treated in the step c on the diaphragm spring continuously punching die; e: pre-cutting and dropping the raw material treated in the step d on the diaphragm spring continuously punching die; f: transversely pushing the raw material treated in the step e on the diaphragm spring continuously punching die to the next station; g: pressing the outer round corner on the raw material treated in the step f on the diaphragm spring continuously punching die. The continuous punching method of the diaphragm spring, disclosed by the invention, has the advantages that the working efficiency can be increased and the utilization rate of the materials can be also increased.
