A limiting edge block 901 is vertically upward provided at the outer edge of the side support table 9. The inner edge of the limiting edge block 901 is of an inclined cutting surface structure, which is convenient for the aluminum alloy plate 8 of the power distribution cabinet to be clamped, realizing stamping of dimensioned fittings. A stamping cylinder 201 is vertically installed in the middle of the top plane of the supporting vertical plate 2.

The upper ends of the guide rods 401 vertically slide through the top plate of the supporting vertical plate 2, which is used to ensure the directional track of the vertical movement of the upper die 4. When the upper die 4 moves downward, the correction frame 5 can be driven to move downward by the limiting guide rod 402 and the spring A403. When the rotating shaft of the correction roller 501 on the correction frame 5 is caught in the limiting card slot 60301, the upper die 4 continues to move downward, while the correction frame 5 stops moving downward. At this time, the correction roller 501 of the correction frame 5 can cooperate with the bending roller 602 to bend the aluminum alloy plate 8 of the power distribution cabinet. The rotatable correction roller 501 and bending roller 602 can reduce the wear and damage to the aluminum alloy plate 8 of the power distribution cabinet. Cooperating with the continuous downward movement of the upper die 4 for stamping, the aluminum alloy plate 8 of the power distribution cabinet will be stamped into a concave structure.
