A trapezoidal support frame is arranged at the central position above the operating table. Positioning lead screws are slidably arranged on both sides of the front end of the trapezoidal support frame respectively. Bending knife cylinders are arranged on both sides above the trapezoidal support frame respectively. The lower part of the bending knife cylinder is connected with a bending knife. Both sides of the bending knife are fixedly connected with the lower parts of two positioning lead screws respectively. A pressing plate cylinder is arranged at the rear end of the trapezoidal support frame. The lower part of the pressing plate cylinder is connected with a pressing plate. Connecting shafts are longitudinally arranged on both sides of the rear end of the operating table respectively. Guide rollers are rotatably arranged outside the connecting shafts. A sandwich panel is arranged between the two guide rollers.
[0005] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0006] By setting positioning lead screws and anti-loosening positioning nuts, the bending knife can be positioned by the anti-loosening positioning nuts in cooperation with the positioning lead screws, and then the stop position when the folding and bending knife presses down can be adjusted, which is convenient for the production of plates with different thicknesses.
[0007] By setting a pressing plate cylinder, a pressing plate and guide rollers, by placing the sandwich panel between the two guide rollers and driving the pressing plate to descend by the pressing plate cylinder to press the sandwich panel, the sandwich panel can be prevented from running off when being bent.
[0008] By setting a bending knife cylinder and a bending knife, by driving the bending knife to descend by the bending knife cylinder and manually rotating the sandwich panel and slowly lifting the sandwich panel until the angle is appropriate and then stopping the action, it is convenient to bend the sandwich panel.
