Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In order to solve the technical problems that the clamping structure in the prior art has a general bending effect and no protective measures for sheet metal parts when cooperating with the bending work, please refer to Figures 1-4 to provide the following technical solutions:

[0024] In this embodiment, an adjustable clamping structure for sheet metal processing and bending includes a bottom plate 1. Above the bottom plate 1, there is a placement rack 5. The bottom plate 1 is fixedly connected to the placement rack 5 through a vertical plate 2 and a column 3 to play a supporting role. And the column 3 is located at the front end of the vertical plate 2, which is convenient for taking the sheet metal parts that fall on the backing plate 7. Inside the placement rack 5, there is a width adjustment mechanism 6, which can adjust the distance between the two rotating rollers 604 according to the size of the sheet metal parts, so that the sheet metal parts can be placed on the two rotating rollers 604. Above the width adjustment mechanism 6, there is a clamping mechanism 4 for positioning the sheet metal parts. On the upper end surface of the bottom plate 1, there is a backing plate 7. The sheet metal parts to be bent fall on the backing plate 7. The backing plate 7 is made of a compressive material, such as plastic foam, which can prevent the sheet metal parts from being damaged when they fall.

[0025] In this embodiment, the width adjustment mechanism 6 includes two moving frames 601. At the front and rear ends of the moving frame 601, there are sliders 605. The sliders 605 are slidably connected to the placement rack 5 through the chutes 501. On both sides of the placement rack 5, there are second threaded sleeves 603. On one side of the moving frame 601, there is a screw 602 fixedly arranged, and one end of the screw 602 passes through the placement rack 5 and is threadedly connected to the second threaded sleeve 603. By rotating the screw 602, the moving frame 601 can be driven to move, thereby adjusting the position of the rotating roller 604. Through the cooperation of the sliders 605 and the chutes 501, the smooth movement of the moving frame 601 is ensured.

[0026] Inside the moving frame 601, a rotating roller 604 is provided. Both ends of the rotating roller 604 are rotatably connected to the moving frame 601 through bearings. A protective sleeve 606 is sleeved on the outer wall of the rotating roller 604, which plays a role in protecting the surface of the sheet metal part.

[0027] In this embodiment, the clamping mechanism 4 includes a support frame 401. The support frame 401 is fixedly arranged at the upper end of the moving frame 601. Inside the support frame 401, a pressing plate 404 is provided, and the pressing plate 404 is located above the rotating roller 604. A protective layer 406 is provided on the lower surface of the pressing plate 404. When the moving frame 601 moves, it can drive the support frame 401 to move together. When the pressing plate 404 contacts the sheet metal part, the protective layer 406 plays a role in protecting the surface of the sheet metal part.

[0028] A first threaded sleeve 405 is provided at the upper end of the support frame 401. A lead screw 403 is provided at the upper end of the pressing plate 404. One end of the lead screw 403 penetrates through the support frame 401 and is threadedly connected to the first threaded sleeve 405. Guide rods 402 are provided on both sides of the lead screw 403. One end of the guide rod 402 is fixedly connected to the pressing plate 404, and the other end of the guide rod 402 penetrates through the support frame 401. By rotating the lead screw 403, the pressing plate 404 can be driven to approach and press the sheet metal part, and the guide rod 402 plays a guiding role.

[0029] Working principle: During use, first adjust the distance between the two rotating rollers 604 according to the size of the sheet metal part. By rotating the screw 602, the moving frame 601 can be driven to move, thereby adjusting the position of the rotating roller 604. After adjustment, place the sheet metal part to be bent on the two rotating rollers 604. By rotating the lead screw 403, the pressing plate 404 can be driven to approach and press the sheet metal part to position the sheet metal part. After clamping and fixing the sheet metal part, the bending work is carried out. After the sheet metal deforms, it falls on the backing plate 7 and can be taken out.
