The plate to be bent is placed on the bending block 4, the top of the bending block 4 is flush with the bottom of the concave frame 12, and the two ends of the plate are placed in the concave frame 12 on the movable plate 7. The rotating block 15 is driven The extrusion rod 14 rotates and moves downward, and the extrusion rod 14 moves and drives the pressure plate 13 to fit the surface of the plate, which can clamp and fix plates of different thicknesses, improve the clamping and positioning effect of the plate, and do not need to be manually held and fixed, which reduces the danger. The cylinder 5 is started to drive the bending knife 6 to move downward, so that the bending knife 6 can bend the plate. During the bending process, the two ends of the plate will rotate and tilt upward, and the plate will move upward, and the return spring 10 will be stretched. When the rotation angle is large, the return spring 10 drives the slider 9 to slide in the T-slot 8 to avoid the return spring 10 being subjected to excessive deformation force and causing the elasticity to decrease, affecting the service life of the return spring 10. The coordinated use of the slider 9 and the return spring 10 reduces the possibility of the plate being offset during the bending process. The structure is simple and easy to operate. When in use, the cylinder 5 and the forward and reverse motors 17 are controlled by the connected power supply and control switch set on the operating table 1. The circuits and modules involved are all existing technologies, which can be fully implemented by those skilled in the art without further explanation.

[0018] Furthermore, the clamping assembly includes a concave frame 12, a pressure plate 13, an extrusion rod 14 and a rotating block 15.

[0019] Furthermore, one side of the pressing plate 13 abuts against the inner wall of the concave frame 12 to prevent the pressing plate 13 from rotating when the extrusion rod 14 rotates, so that the pressing plate 13 slides up and down on the inner wall of the concave frame 12, thereby increasing the connectivity between the pressing plate 13 and the concave frame 12.

[0020] Furthermore, the bottom of the pressing plate 13 and the inner bottom of the concave frame 12 are both fixedly connected with anti-skid pads 16, which can protect the surface of the plate, prevent damage to the clamping position of the plate, and improve the fixing effect of the plate.

The top of the moving block 19 is fixedly connected to the bottom of the movable plate 7. The forward and reverse motor 17 is started to drive the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the two moving blocks 19 to slide closer or farther away in the groove 11.

During the bending process, the two ends of the sheet will rotate and tilt upward, the sheet will move upward, and the reset spring 10 will be stretched. When the rotation angle is large, the reset spring 10 drives the slider 9 to slide in the T-slot 8 to avoid the reset spring 10 being subjected to excessive deformation force, resulting in reduced elasticity, affecting the service life of the reset spring 10, and the coordinated use of the slider 9 and the reset spring 10 reduces the possibility of sheet deviation during the bending process.
