The electric push rod 9 is fixedly connected to the surface of the support seat 8. The bottom plate 10 is fixedly connected to the lifting end of the electric push rod 9.

The hydraulic lifting device 3 can be used to lift and lower the lifting rod 19;

[0027] During use, the hydraulic lifting device 3 can be used in cooperation with the lifting rod 19 to bend the workpiece by the cooperation of the bending tool 6 arranged on the surface of the upper template 5 and the lower template 2. Then, when the electric push rod 9 is lifted and lowered, the pressure plate 11 moves downward, and the pressure plate 11 can be used to press the surface of the workpiece to avoid the problem of workpiece offset during bending.

The pressurizing mechanism is displaced inside the support frame 4 by the rotation of the movable screw 7. The position detection module 20 can detect the position of the workpiece. Therefore, the pressurizing plate 11 can be moved to the middle of the workpiece before the workpiece is bent, and can be accurately positioned to avoid lateral deviation of the pressurizing structure due to different workpiece sizes and placement positions when the middle is pressurized. The middle of the workpiece is pressurized when the workpiece is bent, thereby preventing deformation in the middle of the product and achieving high-precision product processing. This avoids the problems of lateral deviation, slippage, and bending rebound of the steel plate caused by insufficient pressure in the middle of the traditional bending machine body 1 when the workpiece is bent.
