The rotating ends of the two sets of support bars 31 are installed with torsion springs 32 fixedly connected to the workbench 1. Scale dials 33 are provided on both sides of the workbench 1 near the rotating ends of the support bars 31. Pointers 34 are installed on the rotating ends of the support bars 31 near the sides of the scale dials 33.

[0025] The two groups of support bars 31 fit together and their upper surfaces are flush with the support seat 23, the bottom of the cutter head 22 is located between the two groups of support bars 31, and the support seat 23 fits the lower end of the side of the support bar 31; one end of the torsion spring 32 is fixedly connected to the workbench 1, and the other end of the torsion spring 32 is fixedly connected to the rotating end of the support bar 31; let the end of the plate to be bent be between the two groups of support bars 31, and the hydraulic cylinder assembly 21 drives the cutter head 22 to bend the plate. During the force transmission, the plate bending section drives the two groups of support bars 31 to rotate, and the rotating end of the support bar 31 drives the pointer 34 to rotate and compress the torsion spring 32, and the bending angle of the plate is read through the cooperation of the dial 33 and the pointer 34, so that the plate is bent to a suitable angle. When the cutter head 22 is separated from the plate, the support bar 31 is reset under the action of the torsion spring 32 and the bent end of the plate is lifted up;

[0026] The second embodiment differs from the first embodiment mainly in that:

[0027] The horizontal limiter 24 includes a motor 241 mounted on the left side of the workbench 1. The output end of the motor 241 is coaxially fixedly connected to a bidirectional screw 242 that is rotatably connected to the support base 23. Both sides of the bidirectional screw 242 are threadedly connected to a slide frame 243 that is slidably connected to the support base 23.
