The second cylinder 402 is extended and retracted to drive the conveying platform 403 to move and adjust the distance between the two conveying platforms 403. Such an arrangement can support larger metal plates. When the electromagnet 408 is energized, the metal plate is pressed against the upper surface of the conveyor belt 406, thereby increasing the friction between the conveyor belt 406 and the metal plate. The conveyor belt 406 rotates to drive the metal plate to move to the bending platform 102 for bending.

[0028] A second motor 404 is fixedly connected to one side of the support platform 401, and a moving gear 405 is rotatably connected to the lower part of the support platform 401.

The vertical movement of the sliding rod 302 drives the pressing blocks 303 to move downward to press the metal plate. The pressing blocks 303 press the metal plate to prevent the metal plate from moving when bending.

[0032] The rotation adjustment mechanism includes a third cylinder 501. A cavity is provided in the center of the support platform 401. The third cylinder 501 is fixedly connected to the bottom of the cavity in the support platform 401. The output end of the third cylinder 501 is fixedly connected to a vertical movable bracket 502.

Since the moving gear 405 is engaged with the rack 105, the moving gear 405 rotates and drives the supporting platform 401 to move along the direction of the rack 105. This setting can drive the metal plate to move horizontally, and the metal plate moves forward to the bending platform 102. The first cylinder 301 extends and retracts to drive the sliding rod 302 to move vertically. The vertical movement of the sliding rod 302 drives the pressure block 303 to move downward to press the metal plate. The block 303 presses the metal plate to prevent the metal plate from moving during bending. The first motor 205 rotates to drive the second bevel gear 204 to rotate.

When the bending position of the metal plate needs to be adjusted, the metal plate retreats and leaves the bending platform 102. The third cylinder 501 extends and retracts to drive the vertical movable bracket 502 to extend and retract. The third motor 504 rotates to drive the rotating support plate 503 to rotate. The third cylinder 501 lifts the metal plate. The third motor 504 rotates to drive the metal plate to rotate, so that the folded position of the metal plate can be adjusted.
