[0027] Based on the above structural setting, the high-precision, high-efficiency, multi-process composite stamping die is composed of a top plate 1, a bottom plate 2, a punching mechanism 3 and a stamping mechanism 4, wherein the top plate 1 and the bottom plate 2 are used to connect the device with an external stamping power structure, the punching mechanism 3 is used to punch the workpiece, the stamping mechanism 4 is used to stamp and deform the workpiece, and the stamping mechanism 4 is used to cut and bend the workpiece. Specifically, during the working process, the top plate 1 and the bottom plate 2 are connected to the external structure. During assembly, the top plate 1 needs to be located directly above the bottom plate 2 and parallel to each other. The position of the clamping plate 8 is adjusted by rotating the bidirectional threaded rod 9 to reserve a gap between the clamping plates 8 to allow the workpiece to be processed. The workpiece is passed through the clamping plates 8 and moved to the top of the lower mold 303. Driven by the external power, the top plate 1 is used to The upper die 301 and the lower die 303 are used to punch the workpiece. After the processing is completed, the workpiece is moved again so that the workpiece is moved to the bottom of the stamping mechanism 4. When punching again, the workpiece is cut off by the height difference between the cutting knife at the bottom of the die 401 and the lower die 303.
