Above the mounting seat 61, there are two vertical plates 62. Between the two vertical plates 62, two first movable blocks 621 are rotatably arranged. On the opposite sides of the two first movable blocks 621, movable seats 63 are fixedly arranged. On the opposite sides of the two movable seats 63, second movable plates 631 are slidably arranged. On the opposite sides of the two second movable plates 631, mounting blocks 64 are fixedly arranged. On the right side of the mounting block 64, there is a second movable block 641. At the bottom of the second movable block 641, a bottom plate 642 is fixedly arranged. On the top of the bottom plate 642, a second threaded rod 645 is rotatably arranged. The surface of the second threaded rod 645 is threadedly connected with a clamping plate 643. The left side of the clamping plate 643 is slidably connected with the right side of the second movable block 641. At the top of the second threaded rod 645, a first handwheel 646 is fixedly arranged; On the left side of the movable seat 63, two second guide rods 635 are fixedly arranged.

On the left side of the movable seat 63, a through groove for the plurality of limiting blocks 633 to slide is opened. On the left side of the second movable plate 631, a limiting groove for the plurality of limiting blocks 633 is opened. The left side of the limiting plate 632 and the left end of the second guide rod 635 are connected by a first return spring, and the first return spring is sleeved on the surface of the second guide rod 635; On the top of one of the vertical plates 62, a second horizontal plate 622 is fixedly arranged.

Further pull the limiting plate 632 to the left, thereby driving the multiple limiting blocks 633 to move to the left. At this time, the limiting blocks 633 are separated from the limiting grooves, thereby releasing the limitation on the second movable plate 631. Then, the second movable plate 631 can be pulled according to the length of the sheet metal part. The second movable plate 631 drives the mounting block 64 to move, thereby driving the second movable block 641 to move, and then driving the bottom plate 642 and the clamping plate 643 to move. After moving to the appropriate position, further rotate the first handwheel 646, thereby driving the second threaded rod 645 to rotate, and then the clamping plate 643 moves downward until the front and rear ends of the sheet metal part are clamped by the bottom plate 642 and the clamping plate 643, realizing the limitation of the sheet metal part. At this time, the sheet metal part is bent by the bending part 5. During the bending process, the two ends of the sheet metal part will tilt upward. Since two first movable blocks 621 are rotatably arranged between the two vertical plates 62, the movable seat 63 can be driven to rotate, thereby driving the second movable plate 631 to rotate, then driving the mounting block 64 to rotate, then driving the second movable block 641 to rotate, and then driving the bottom plate 642 and the clamping plate 643 to rotate, so as to drive the end of the sheet metal part to rotate, avoiding the problem of increasing the working danger coefficient by manually limiting the sheet metal part, reducing the working danger coefficient. At the same time, the limiting component 6 can move along with the movement of the sheet metal part, avoiding the problem that the sheet metal part deviates when the limiting component 6 is fixedly arranged and the sheet metal part moves, and further ensuring the accuracy of the bending position.

[0037] Working principle: When it is necessary to fix the sheet metal parts on both sides, first place the sheet metal parts on the tops of the two fixing bars 3, and the bending part is directly below the bending part 5. Further pull the limiting plate 632 to the left, which drives a plurality of limiting blocks 633 to move to the left. At this time, the limiting blocks 633 are separated from the limiting grooves, thereby releasing the limitation on the second movable plate 631. Then, the second movable plate 631 can be pulled according to the length of the sheet metal parts. The second movable plate 631 drives the mounting block 64 to move, which drives the second movable block 641 to move, and then drives the bottom plate 642 and the clamping plate 643 to move. After moving to the appropriate position, further rotate the first handwheel 646, which drives the second threaded rod 645 to rotate, and then the clamping plate 643 moves downward until the front and rear ends of the sheet metal parts are clamped by the bottom plate 642 and the clamping plate 643, realizing the limitation of the sheet metal parts. At this time, the sheet metal parts are bent by the bending part 5. During the bending process, the two ends of the sheet metal parts will tilt upward. Since two first movable blocks 621 are rotatably arranged between the two vertical plates 62, the movable seat 63 can be driven to rotate, which drives the second movable plate 631 to rotate, then drives the mounting block 64 to rotate, then drives the second movable block 641 to rotate, and then drives the bottom plate 642 and the clamping plate 643 to rotate, thereby driving the end of the sheet metal parts to rotate, avoiding the problem of increasing the working danger coefficient by manually limiting the sheet metal parts, reducing the working danger coefficient.
