After the U-shaped support 9e jacks up the metal sheet 12, the bending cylinder 7k synchronously moves, the pressing block 7m is punched into the bending cavity 8b to press the metal sheet 12 in the bending cavity 8b, the pressing block 7m and two open ends of the U-shaped support 9e are spliced to form a rectangular structure, the structure of the pressing block 7m is also in a step shape, two open ends of the U-shaped support 9e can be avoided, meanwhile, in the movement of the U-shaped support 9e, only the part, which is not pressed by the pressing block 7m, of the metal sheet 12 can be jacked up, the pressing block 7m can be lifted and reset finally, the U-shaped support 9e is reset, and the bent elastic sheet 13 is pushed out by the bending rod 8e3 finally, so that the back side of the punching table 8 is provided with the discharge port 10, and the discharge port 10 is communicated with the bending cavity 8 b.

The working principle is as follows: the manipulator horizontally places the metal sheets 11 on the transfer bin 1 one by one, then the metal sheets are moved by a piston of the feeding cylinder 2 and matched with the material pushing plate 2a, so that the metal sheets 11 are pushed to the two punching blocks, the lifting electric pole 1c drives the lifting block 1e to slowly descend, the lifting block 1e is matched with the feeding cylinder 2, a plurality of metal sheets 11 are finally overlapped and stacked on the lifting block 1e in order to stack a plurality of metal sheets 1c to a large number, the lifting electric pole 1c slowly moves, the output rod slowly lifts the lifting block 1e, the metal sheet 11 at the top layer is firstly close to the traveling wheel 3b, the traveling wheel 3b is rotated by the traveling motor 3a at the moment, and the rotation generates friction with the metal sheets 11, so that the metal sheets 11 are driven by friction, then the metal sheets 11 are driven into the two mounting plates 4a, and the top ends of the metal sheets 11 pass below the anti-warping wheel, if the metal sheet 11 is upwarped, the metal sheet 11 is contacted by the upwarped rollers and is limited by correction, then the metal sheet 11 enters between the two power rollers 4c, and the metal sheet 11 smoothly passes through a plurality of friction rollers 4e by the autorotation of one power roller 4c and then enters into two correction discs 4m by matching with the traveling wheel 3b, the side edge of the metal sheet 11 is contacted with the correction discs 4m and is subjected to friction transition by the correction cambered surfaces 4m1, so that the metal sheet 11 enters onto the punching table 8 in a preset posture, after the metal sheet 11 slowly moves on the punching table 8 and reaches the lower part of the punching cylinder 7a, the piston of the punching cylinder 7a descends to ensure that the rectangular plate 7b descends, then the piston of the lower die cylinder 9b firstly contacts the surface of the metal sheet 11, and at the same time, the piston of the lower die cylinder 9b is upwards pushed to push the lower die block 9c into the punching cavity 8a, the end face of a lower die block 9c is flush with the end face of a punching table 8, then a punching cutter die 7e is matched to punch a metal sheet 12, then a lower die cylinder 9b is reset by a piston, the metal sheet 12 is driven to enter a punching cavity 8a through the lower die block 9c, the formed metal sheet 12 is pushed into a bending cavity 8b by a material pushing plate 9a through a material pushing plate 9a at the moment, two bending rods 8e3 are matched by a power motor 8e1 and a gear, two bending rods 8e3 move towards the bending cavity 8b through a bending through groove 8e4, at the moment, a U-shaped support 9e moves through the work of an auxiliary cylinder 9d, the two open ends of the U-shaped support move in a moving groove, meanwhile, a bending cylinder 7k synchronously moves, a pressing block 7m is pushed into the bending cavity 8b to press the metal sheet 12 in the bending cavity 8b, and the pressing block 7m and the two open ends of the U-shaped support 9e are spliced to form a rectangular structure, due to the arrangement of the pressing block 7m, the U-shaped support 9e can only lift and jack the part of the metal sheet 12, which is avoided by the pressing block 7m, and then the part of the metal sheet 12, which is jacked by the two open ends of the U-shaped support 9e, is jacked by the bending rod 8e3 by matching with the front end propelling force of the bending rod 8e3, so that the bending is realized, after the metal sheet 11 is punched, waste materials on two sides of the metal sheet can pass through the leading-out wheel 6a, the leading-out wheel 6a works by the servo motor 6b, the waste materials are smoothly led out, the waste materials are led out by the leading-out wheel 6a and then can be landed on the lifting plate 6d, and the lifting plate 6d can descend, so that the waste materials slowly descend and are manually centralized to be.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
