Description

Technical Field

[0001] This utility model relates to the technical field of bending devices, and in particular to a bending device for sheet metal processing. Background Technology

[0002] Sheet metal is a general term for thin metal sheets, commonly made of materials such as steel, aluminum, and copper. Originally, thin metal sheets are usually flat and cannot be directly used in the manufacture of various products. Therefore, they need to be processed to give them specific shapes and functions. Bending is a crucial step in sheet metal processing because many products require specific angles, curvatures, or three-dimensional shapes. For example, the housings of mechanical equipment, automotive parts, and electrical appliance frames all require bending to process flat thin sheets into shapes that meet design requirements, enabling them to perform assembly, support, and protection functions, and satisfying the product's needs in terms of structural strength, space utilization, and performance.

[0003] However, existing bending devices cause sheet metal to warp during use, causing its shape to deviate from the design requirements, affecting the accuracy of subsequent assembly, making it difficult to assemble parts smoothly, and reducing the structural stability of the sheet metal, weakening its load-bearing capacity and service life. Utility Model Content

[0004] The purpose of this utility model is to provide a bending device for sheet metal processing. By setting an anti-warping part, it solves the problem that the sheet metal will warp during use, causing its shape to deviate from the design requirements, affecting the accuracy of subsequent assembly, making it difficult to assemble parts smoothly, and reducing the structural stability of the sheet metal, weakening its load-bearing capacity and service life.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a bending device for sheet metal processing, comprising a worktable and an upper die disposed above the worktable. The top of the worktable has a groove. The device further includes: a guide portion mounted on the worktable; an anti-warping portion disposed above the worktable; a lifting portion mounted on the top of the worktable; the anti-warping portion includes an anti-warping assembly mounted above the worktable; and a telescopic assembly mounted on the anti-warping assembly. The anti-warping assembly includes two support frames disposed above the worktable, each with a rotating shaft rotatably connected to its inner wall, and pressure rollers fixedly connected to the outer walls of each rotating shaft. The two support frames are respectively disposed on the left and right sides of the upper die.

[0007] Furthermore, the guide section includes two guide plates fixedly connected to the top of the workbench, and several support legs fixedly connected to the bottom of the workbench; the two guide plates are mirror images of each other with the groove as a reference, and are used to guide the sheet metal.

[0008] Furthermore, the lifting unit includes a lifting assembly mounted on the top of the worktable; and a limiting assembly mounted on the lifting assembly; the limiting assembly is used to limit the lifting assembly.

[0009] Furthermore, the telescopic assembly includes two L-shaped support plates fixedly connected to the top of the upper mold, two sliding rods fixedly connected to the top of each of the two support frames, the tops of several sliding rods penetrating through the two L-shaped support plates, and elastic elements provided on the outer walls of the several sliding rods; the several sliding rods are slidably connected to the two L-shaped support plates to limit the elastic elements.

[0010] Furthermore, the lifting assembly includes a second support frame fixedly connected to the top of the worktable, a threaded rod rotatably connected to the top of the upper mold, the top of the threaded rod passing through the second support frame, and a handle fixedly connected to the top of the threaded rod; the threaded rod is threadedly connected to the second support frame, and the handle is located above the second support frame.

[0011] Furthermore, the limiting component includes guide rails fixedly connected to the inner walls of the front and rear sides of the support frame, and sliding blocks are slidably connected to the inner walls of the two guide rails. The sides of the two sliding blocks that are close to each other are fixedly connected to the upper mold. Slide grooves are provided on the sides of the two guide rails that are close to each other, and the two sliding blocks are located in the two slide grooves respectively.

[0012] Furthermore, the elastic part includes springs respectively sleeved on the outer wall of several sliding rods, the tops of several springs are fixedly connected to two L-shaped support plates, and the bottoms of several springs are fixedly connected to two support frames; the springs have elastic force in their normal state.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up anti-warping parts, the pressure roller can always press the sheet metal to be bent under the action of the spring, effectively preventing the sheet metal from warping during the bending process, ensuring that its shape meets the design requirements, which is conducive to subsequent assembly. In addition, the rotation setting of the rotating shaft converts the sliding friction between the sheet metal and the pressure roller into rolling friction, reducing damage to the sheet metal.

[0015] 2. By setting up a lifting part, the threaded rod can be rotated by turning the handle, which allows the upper die to move down stably with the cooperation of the guide rail and sliding block, pressing the sheet metal into the groove and smoothly completing the bending, ensuring the convenience of the bending operation.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figure 1-5As shown, this utility model is a bending device for sheet metal processing, including a workbench 111 and an upper die 112 disposed above the workbench 111. The top of the workbench 111 has a groove 113. It also includes: a guide part 1, which is installed on the workbench 111 and includes two guide plates 114 fixedly connected to the top of the workbench 111. Several support legs 115 are fixedly connected to the bottom of the workbench 111. The two guide plates 114 are mirror images of each other with the groove 113 as a reference; an anti-warping part 2, which is disposed above the workbench 111; and a lifting part 3, which is installed on the top of the workbench 111.

[0027] The anti-warping part 2 includes an anti-warping component 21, which is installed above the worktable 111; and a telescopic component 22, which is installed on the anti-warping component 21. The anti-warping component 21 includes two support frames 211 disposed above the worktable 111. A rotating shaft 212 is rotatably connected to the inner wall of each of the two support frames 211, and a pressure roller 213 is fixedly connected to the outer wall of each of the two rotating shafts 212. The two support frames 211 are respectively disposed on the left and right sides of the upper mold 112. The telescopic component 22 includes two L-shaped support plates 221 fixedly connected to the top of the upper mold 112. Two sliding rods 222 are fixedly connected to the top of each of the two support frames 211, and the tops of several sliding rods 222 penetrate the two L-shaped support plates 221. The outer wall of 222 is provided with elastic elements; several slide rods 222 are slidably connected to two L-shaped support plates 221. The elastic part includes springs 223 respectively sleeved on the outer wall of several slide rods 222. The top of several springs 223 is fixedly connected to the two L-shaped support plates 221, and the bottom of several springs 223 is fixedly connected to two support frames 211. The springs 223 have elasticity under normal conditions. By setting the anti-warping part 2, the pressure roller 213 can always press the sheet metal to be bent under the action of the springs 223, effectively avoiding warping of the sheet metal during the bending process, ensuring that its shape meets the design requirements, facilitating subsequent assembly. Furthermore, the rotation setting of the rotating shaft 212 converts the sliding friction between the sheet metal and the pressure roller 213 into rolling friction, reducing damage to the sheet metal.

[0028] The lifting unit 3 includes a lifting assembly 31, which is mounted on the top of the worktable 111; and a limiting assembly 32, which is mounted on the lifting assembly 31. The limiting assembly 32 is used to limit the lifting assembly 31. The lifting assembly 31 includes a support frame 311 fixedly connected to the top of the worktable 111. A threaded rod 312 is rotatably connected to the top of the upper mold 112. The top of the threaded rod 312 passes through the support frame 311, and a handle 313 is fixedly connected to the top of the threaded rod 312. The threaded rod 312 is threadedly connected to the support frame 311, and the handle 313 is located above the support frame 311. The limiting assembly 32 includes... The support frame 311 includes guide rails 321 fixedly connected to the inner walls of the front and rear sides respectively. Sliding blocks 322 are slidably connected to the inner walls of the two guide rails 321. The sides of the two sliding blocks 322 that are close to each other are fixedly connected to the upper mold 112. The sides of the two guide rails 321 that are close to each other are provided with grooves. The two sliding blocks 322 are located in the two grooves respectively. By setting up the lifting part 3, the threaded rod 312 can be rotated by rotating the handle 313. The upper mold 112 can be stably moved down under the cooperation of the guide rails 321 and the sliding blocks 322, pressing the sheet metal into the groove 113 and completing the bending smoothly, ensuring the convenience of the bending operation.

[0029] A specific application of this embodiment is as follows: In use, the sheet metal to be bent is first placed above the workbench 111 and positioned between the two guide plates 114. When the sheet metal needs to be bent, the handle 313 can be turned to drive the threaded rod 312 to rotate. During this process, the upper die 112 will move downward under the interaction of the guide rail 321 and the sliding block 322 until the sheet metal is pressed into the groove 113, thus completing the bending of the sheet metal. Before the upper die 112 touches the sheet metal to bend it, the pressure roller 213 will touch the sheet metal first. As the upper die 112 moves downward, due to the elasticity of the spring 223 on the slide rod 222, the pressure roller 213 will always press the sheet metal to be bent tightly to prevent the sheet metal from warping during the bending process. During the bending process, due to the rotation setting of the rotating shaft 212, the sliding friction between the sheet metal and the pressure roller 213 is converted into rolling friction.
