The plate is placed between the bending frame 5 and the bending press block 106 according to the specific use and working principle, the hydraulic device 105 is started to enable the bending press block 106 to move downwards so as to press and bend the plate, and when the plate is bent, one side, close to the bending press block 106, of the rotating frame 501 is pressed by the bending press block 106, and then the rotating frame 501 is driven to rotate so as to enable the bending plate 503 to bend the plate;
In the bending process, as the two sides of the bending press block 106 squeeze the plate due to the thickness of the plate, the bending base 4 is pushed to move away from each other, the bending base 4 and the bending frame 5 can keep being attached to the plate under the action of the elasticity of the compression spring 7, when the sliding plate 402 moves along the sliding guide rail 102, the rack 403 drives the gear 202 to rotate, and the transmission shaft 203 and the screw 204 rotate under the acceleration action of the transmission 201, the screw 204 drives the moving block 207 to move along the transverse guide rail 206, and the moving block 207 pushes the lifting plate 208 to move upwards through the connecting rod 209, so that the lifting plate 309 is driven to move upwards, and the trigger plate 310 is lifted upwards;

Because the thickness of the plate pushes the bending base 4 to move along the sliding guide rail 102, the trigger plate 310 is lifted, when the plate is thicker, the lifting height of the trigger plate 310 is higher, so that the pressing distance of the pressing block 507 to the trigger plate 310 is larger, the rotation amount of the bending plate 503 is larger, and the excessive bending angle of the plate is increased; when the thickness of the plate is smaller, the excessive bending angle of the bending plate 503 to the plate is correspondingly smaller, so that the excessive bending angle can be changed according to the thickness adaptability of the plate;
