The upper ends of the slide seats 8 are provided with telescopic mechanisms, which can move up and down in the vertical direction, and two groups of telescopic mechanisms on the same side are rotatably connected to the fixing mechanism by setting a rotating shaft 9. The two groups of fixing mechanisms are located on both sides of the lower mold 5, and the fixing mechanisms can position both sides of the sheet metal.

[0018] Furthermore, the stamping mechanism includes a frame 2 fixedly mounted on the base 1 , a hydraulic cylinder 3 fixedly mounted on the top of the frame 2 , the hydraulic cylinder 3 is vertically arranged, and a stamping die 4 is fixedly connected to the telescopic end of the hydraulic cylinder 3 .

[0019] Furthermore, the punching die 4 is located above the lower die 5 , and the punching die 4 is aligned with the lower die 5 .

[0020] In this embodiment, the fixing mechanisms provided on both sides of the lower die 5 are used to fix the two ends of the sheet metal. Compared with manual holding, the bending position of the sheet metal is more accurate and the safety during bending is improved. By setting the telescopic mechanism, the slide 7 and the slide seat 8, the fixing mechanism can move in both the vertical and horizontal directions, and by setting the rotating shaft 9 to cooperate with the fixing mechanism, the fixing mechanism can also deflect; in this embodiment, the lower die 5 is a V-shaped groove structure, and the shape of the stamping die 4 matches the lower die 5. When the hydraulic cylinder 3 drives the stamping die 4 to move down into the lower die 5, the sheet metal is bent, and the two ends of the sheet metal will be tilted upward. The fixing mechanisms on both sides can cooperate with the two ends of the sheet metal to perform corresponding displacement. In this process, the fixing mechanism can support the sheet metal and maintain the stability of the sheet metal during bending.

[0021] Furthermore, the telescopic mechanisms include a telescopic rod 13 arranged on the slide 8, the telescopic rod 13 can be moved in or out from the upper end of the slide 8 in the vertical direction, the upper end of the telescopic rod 13 is fixedly connected with a connecting head 14, and a spring 15 is sleeved on the surface of the telescopic rod 13, one end of the spring 15 is fixedly connected to the slide 8, and the other end of the spring 15 is fixedly connected to the connecting head 14, and the connecting head 14 is rotatably connected to the rotating shaft 9.

[0022] In this embodiment, when the two ends of the sheet metal are tilted upward, the connecting head 14 and the telescopic rod 13 will be driven to move upward, and the spring 15 sleeved on the telescopic rod 13 will be stretched. After the sheet metal is bent, the sheet metal is taken out from the fixing seat 10, and the stretched spring 15 moves back, driving the telescopic rod 13 and the connecting head 14 to reset.

[0025] It should be noted that when taking out the bent sheet metal part, first, loosen the fixing bolts 11 , and then move the slide seat 8 and the telescopic rod 13 to remove the two ends of the sheet metal part from the through slots 16 of the fixing seat 10 .
