[0034] Working principle: pass the belt-shaped hardware raw material between the driving roller 11 and the compression roller 143, then rotate the screw rod 141 to drive the compression roller 143 to descend and extrude the raw material. When starting to punch, the servo motor 12 drives the driving roller 11 to rotate, and the driving roller 11 drives the belt-shaped raw material to move a specified length towards the surface of the bottom die 2. Then the mold plate 51 is lowered by the hydraulic telescopic rod 4, and the punch 52 contacts the raw material during the lowering process to realize the punching of the raw material. When the mold plate 51 continues to descend, the cutter 53 cuts the raw material, and then the mold plate 51 is lifted and reset by the hydraulic telescopic rod 4. Under the elastic force of the spring 72, the supporting plate 71 is lifted and reset, thereby lifting the punched workpiece from the mold cavity 6. Then the servo motor 12 drives the driving roller 11 to continue to rotate, realizing continuous feeding.
