s2: when the bending knife needs to be replaced, piston rods of a first electric telescopic rod (35) and a second electric telescopic rod (36) are controlled to contract, a servo motor is controlled to drive a fixed sliding roller (15) to rotate, the fixed sliding roller (15) drives a connecting belt (18) to move up and down when rotating, a large-size bending knife (11) and a small-size bending knife (16) can be replaced under the action of the connecting belt (18), the piston rods of the first electric telescopic rod (35) and the second electric telescopic rod (36) are controlled to extend, and two limiting blocks (34) can clamp and limit the bending knife from two sides of the bending knife respectively, so that the automatic replacement of the bending knife can be completed;
s3: after the bending knife is replaced, the piston rod of the hydraulic cylinder (3) is controlled to extend, the pressing plate (2) can move downwards to extrude and fix the surface of the plate, when the plate is completely pressed by the pressing plate (2), the upper contact bulge (28) is contacted with the lower contact bulge (26), the loop is in a communicated state, the display lamp is lightened, and when the plate is not pressed by the pressing plate (2), the display lamp is not lightened, and a worker needs to adjust;
s4: after adjustment, a piston rod of the hydraulic rod (13) is controlled to extend, and the bending knife moves downwards to contact the surface of the plate to extrude and fold the plate until the folded edge reaches a certain angle;
s5: after edge folding, the hydraulic rod (13) and the piston rod of the hydraulic cylinder (3) are controlled to contract, the plate loses the limit, and the plate is taken down from the bending table (10).
