The end of the plate abuts against the surface of the push plate 501. The plate is limited by the baffle 501, which can improve the cutting accuracy and cutting efficiency of the plate.

[0032] Specifically, guide grooves are provided at both ends of the inner cavity of the gantry 2 , an upper cutter 3 is slidably provided in the inner cavity of the guide groove, a lower cutter 4 is provided in the middle of the upper surface of the workbench 1 , and the lower cutter 4 is located below the upper cutter 3 .

[0033] Furthermore, the guide groove can guide the lifting and lowering of the upper cutter 3. When the upper cutter 3 moves downward, the upper cutter 3 and the lower cutter 4 can shear the plate.

[0034] Specifically, the top surfaces of both ends of the push plate 501 are connected with measuring rods 505 , and guide sleeves 504 are welded at the positions of the surfaces of both ends of the gantry 2 corresponding to the positions of the measuring rods 505 , and the measuring rods 505 are plugged into the guide sleeves 504 .

[0035] Furthermore, the guide sleeve 504 can guide the movement of the measuring rod 505. The guide sleeve 504 is located at the incision of the upper cutter 3 and the lower cutter 4.

When the push plate 501 moves, it drives the measuring rod 505 to move synchronously. The measuring rod 505 is guided by the guide sleeve 504 at the end away from the push plate 501. The guide sleeve 504 is located at the incision of the upper cutter 3 and the lower cutter 4. The distance between the push plate 501 and the incision can be measured by matching the guide sleeve 504 with the measuring rod 505, so as to determine the position of the baffle 501 according to the cutting length of the plate. The end of the plate abuts against the surface of the push plate 501. The plate is limited by the baffle 501, which can improve the cutting accuracy and cutting efficiency of the plate. After the cutting is completed, the hydraulic rod 602 is controlled to extend, and the hydraulic rod 602 pushes the lifting plate 603 to lift. The lifting plate 603 simultaneously pushes the ball 605 out of the through hole 607, and the ball 605 can lift the plate. The servo motor 502 drives the push plate 501 through the driving wire shaft 503, and the plate can be quickly pushed out from under the cutter through the push plate 501. When taking out the plate, there is no need to put your hand into the cutter, which can improve the safety during operation. The ball 605 can guide the plate, making it easier to push the plate.
