[0032] The raw material plate 24 is driven by the feeder to move forward according to the set step length and time interval. Every time the raw material plate moves forward, the upper die assembly moves up and down once driven by the press to complete a stamping operation. During the downward movement of the upper die assembly, the pressing plate 6 first contacts the raw material plate, thereby pressing and fixing the raw material plate; then the upper die assembly continues to move downward, and the pressing plate 6 presses against the raw material plate to compress the nitrogen spring, so that the positioning hole punch 8, the shoe hole punch 10, the forming blanking punch 11 and the waste cutting punch 12 extend from the pressing plate 6. During the downward movement of the positioning hole punch 8, the shoe hole punch 10, the forming blanking punch 11 and the waste cutting punch 12, the raw material plate is respectively stamped; after the stamping operation is completed, the upper die assembly moves up under the drive of the press. After the positioning hole punch 8 punches out the positioning hole on the raw material plate for the first time, the positioning pin 9 is inserted into the positioning hole on the raw material plate before the pressing plate presses the raw material plate each time the lower die assembly moves downward, thereby ensuring that the raw material plate is reliably positioned. This cycle is repeated to achieve continuous shoe block punching, forming and blanking, as well as waste cutting operations.
