[0028] Firstly, the thin iron plate is placed on the electromagnet 6, and a part of the thin iron plate is located on the two supporting blocks 3, then the power supply is connected, the electromagnet 6 is energized, the surface of the thin iron plate is tightly adsorbed with the surface of the electromagnet 6, the related reference values on the display screen of the machine body 1 are adjusted, then the switch of the machine body 1 is turned on, the bending tool bit moves downward, the thin iron plate on the supporting block 3 is bent, and the two supporting blocks 3 simultaneously slide relative to the mounting block 2, the thin iron plate and the electromagnet 6 horizontally slide a little, when the bending process is completed, the bending tool bit moves upward, and the two supporting blocks 3 slide relative to the mounting block 2 again and move to the initial position, during the process that the bending tool bit contacts the thin iron plate and moves downward to bend the thin iron plate, the width of the thin iron plate is constant, the end of the thin iron plate away from the processing position is warped during the process that the part of the thin iron plate is bent, and the electromagnet 6 moves upward together with the thin iron plate, since one end of the second sliding rod 8 is limitingly and slidably connected with the first sliding rod 18, and the other end of the second sliding rod 8 is hingedly connected with the lower surface of the electromagnet 6, during the process that the electromagnet 6 inclines with the thin iron plate, the second sliding rod 8 moves upward, and the telescopic rod 11 fixedly connected with the second sliding rod 8 also moves upward;

[0029] Since one end of the telescopic rod 11 slides in the limiting groove 20, the telescopic rod 11 moves upward in the wave groove, when the telescopic rod 11 moves to the uppermost of the wave groove, during the process that the end of the thin iron plate returns to the horizontal state, the electromagnet 6 moves downward, and the second sliding rod 8 also moves downward, since the uppermost of the wave groove has a certain arc, when the telescopic rod 11 moves downward, the telescopic rod 11 slides along the part of the inclined groove of the wave groove, so that the second sliding rod 8 and the first sliding rod 18 move a distance in the horizontal direction, the first sliding rod 18 slides relative to the guide block 17, so that the thin iron plate moves horizontally, the other positions of the thin iron plate are moved to the positions directly below the bending tool bit, then the bending tool bit continues to move downward to bend the thin iron plate at different positions, since one end of the second spring 13 is fixedly connected with the telescopic rod 11, the other end is fixedly connected with the second sliding rod 8, and the telescopic rod 11 is slidably connected with the second sliding rod 8, when the inclination angle of the electromagnet 6 is different, the upward movement distance of the second sliding rod 8 changes, the second sliding rod 8 slides relative to the telescopic rod 11, the above process is repeated, so that the thin iron plate at different positions is bent, and the staff does not need to move the thin iron plate;

[0030] When the second sliding rod 8 and the first sliding rod 18 move to a certain distance, the first sliding rod 18 moves to one end of the guide block 17, and the continuous bending processing of the thin iron plate is just completed. Since the moving block 16 is fixedly connected with the first sliding rod 18, with the horizontal movement of the first sliding rod 18, one end of the moving block 16 also slides in the sliding groove 27 on the fixed block 12. Since the cross section of the sliding groove 27 is arranged as a right trapezoid, and the end surface of the moving block 16 is in contact with the inclined surface of the sliding groove 27, with the horizontal movement of the moving block 16, the relative sliding between the fixed block 12 and the fixed plate 10 is caused. When the moving block 16 moves to one end of the guide block 17 together with the first sliding rod 18, the distance between the fixed block 12 and the first sliding rod 18 reaches the maximum. Since the moving rod 25 is fixedly connected with the fixed block 12, the moving rod 25 also moves together. Since the cross section of the moving rod 25 is arranged as an L shape, the cross section of the extruding block 24 is arranged as a right triangle, and one end of the moving rod 25 abuts against the inclined edge surface of the extruding block 24, with the movement of the moving rod 25, the extruding force on the extruding block 24 becomes smaller. Since one end of the connecting rod 22 is fixedly connected with the limiting plate 21, the other end is fixedly connected with the extruding block 24, one end of the third spring is fixedly connected with the limiting plate 21, and the other end is fixedly connected with the mounting plate 23, after the extruding force on the extruding block 24 becomes smaller, under the elastic force of the third spring, the extruding block 24 moves, the distance between the extruding block 24 and the mounting plate 23 becomes larger, and the limiting plate 21 also moves. The clamping groove on the limiting plate 21 is separated from the clamping block 26 on the guide block 17. Since one end of each first spring 15 is fixedly connected with the fixed plate 10, and the other end is fixedly connected with the guide block 17, without the limiting action of the limiting plate 21, under the elastic force of the first spring 15, the guide block 17 slides in the rectangular groove 19, the telescopic rod 11 is stretched, so that the electromagnet 6 hinged on the second sliding rod 8 moves together, and one end of the thin iron plate moves to one side of the bending tool bit, so that the thin iron plate after the bending processing is conveniently taken out.

[0031] By taking out the plug shaft, the plug shaft is separated from the cover door 5 and the shell 4 at the same time, the cover door 5 is opened, the guide block 17 is moved to one end of the rectangular groove 19 by external force, then the second sliding rod 8 is manually moved downward, so that the telescopic rod 11 fixedly connected on the second sliding rod 8 is slid in the transverse groove of the limiting groove 20, then the fixed rod 9 is manually moved, so that the fixed rod 9, the first sliding rod 18 and the second sliding rod 8 will return to the other end of the guide block 17, the telescopic rod 11 moves to the other end of the transverse groove, then the external force applied on the second sliding rod 8 is removed, under the action of the elastic limiting assembly on the first sliding rod 18, the telescopic rod 11 and the second sliding rod 8 will return to the wave groove again, at the same time, the clamping groove on the limiting plate 21 is clamped with the clamping block 26, then the plug shaft is clamped with the cover door 5 and the shell 4 at the same time, other thin iron plates can be placed on the electromagnet 6, and the continuous bending processing can be carried out, after the thin iron plate is bent once, the staff does not need to manually move the thin iron plate, the thin iron plate can be pushed to the lower side of the bending tool bit, the bending tool bit can bend the thin iron plate at different positions for the next time, the operation is more convenient, the workload of the staff is greatly reduced, and the efficient processing of the thin iron plate is more beneficial.

[0032] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
