The working process of the metal hoop batch stamping machine for the electric power accessories in the embodiment is as follows: in an initial state, the two pressure bearing tables 3 are in a mutually separated state, the bottom surfaces of the lifting plates 501 are attached to the inclined surface of the wedge-shaped plate 504, and the distance between the surface of the metal roller 502 and the upper surface of the pressure bearing table 3 is greater than the thickness of a metal sheet; horizontally placing a plurality of metal sheets between the two pressure bearing tables 3 manually, so that the metal sheets are arranged into a strip shape, and the lower surfaces of the metal sheets are attached to the pressure bearing tables 3; the two supports 2 are driven to move oppositely by rotating the bidirectional screw 8, so that the two pressure bearing tables 3 move oppositely; in the process, the lifting plate 501 moves downwards along the inclined surface of the wedge-shaped plate 504 under the action of gravity and drives the metal roller 502 to descend synchronously until the opposite side surfaces of the two pressure bearing tables 3 are attached to each other, and in the state, the surface of the metal roller 502 is attached to the upper surface of the metal sheet to limit the metal sheet in the vertical direction; the Contraband-shaped frame 403 is driven to move horizontally by rotating the alignment screw 404, the Contraband-shaped frame 403 drives the alignment plate 402 to move horizontally, the alignment plates 402 in the two alignment mechanisms 4 move oppositely until the alignment plates 402 are attached to the end faces of the metal sheets, so that the two alignment plates 402 align the metal sheets, and the end parts of the metal sheets are aligned; the lifting bar 163 is driven to move downwards along the limiting rod 162 by rotating the limiting screw 164, and the lifting bar 163 drives the second wedge-shaped block 166 to push the first wedge-shaped block 165 to move horizontally in the downward movement process of the second wedge-shaped block 166, so that the two limiting blocks 161 are driven to move oppositely; the limiting blocks 161 push the metal sheets at the two ends, and the side faces of the adjacent metal sheets are attached to each other, so that the metal sheets are limited in the horizontal direction, and the metal sheets are prevented from being deviated in the stamping process.

The hydraulic cylinder 601 drives the top plate 602, the connecting column 603 and the stamping block 604 to descend to stamp the metal sheet, the stamping block 604 is firstly contacted with the metal sheet and then extrudes the metal sheet downwards until the lower surface of the metal sheet is attached to the pressure-bearing surface of the pressure-bearing table 3 to form a hoop plate; in the process, the metal sheet is gradually deformed, the part of the metal sheet above the pressure bearing table 3 gradually enters between the stamping block 604 and the pressure bearing surface of the pressure bearing table 3, interaction force is generated between the metal roller 502 and the metal sheet, the metal sheet is always attached to the upper surface of the pressure bearing table 3 through the metal roller 502, and the condition that the metal sheet is irregularly deformed is avoided.

After punching is finished, the hoop plate is attached to the pressure bearing surface of the pressure bearing table 3 to seal the through groove 301, the two supports 2 are driven to move reversely by reversely rotating the bidirectional screw 8, so that the two pressure bearing tables 3 move reversely, the two pressure bearing tables 3 are separated from each other, and the hoop plate positioned between the two pressure bearing tables 3 is separated from the pressure bearing table 3 and falls down under the action of self gravity after losing the bearing function of the pressure bearing tables 3; in the process, the second magnet plate 14 gradually extends into the through groove 301 to be close to the first magnet plate 10, and a mutual repulsion force is generated between the second magnet plate and the first magnet plate 10, the mutual repulsion force overcomes the elastic force action of the return spring 12 to push the first magnet plate 10 to slide towards the hoop plate in the through groove 301, the first magnet plate 10 extrudes air between the hoop plate and the first magnet plate 10, so that the air pressure of the part is increased, the hoop plate is separated from the pressure bearing table 3 through the air pressure action, and the hoop plate separated from the pressure bearing table 3 can fall into the material receiving frame 102.
