[0040] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0041] Example 1, such as Figure 1As shown, the present invention provides a bending device for metal material processing, including a base plate 1, a support frame 5 fixedly connected to the upper surface of the base plate 1, a working plate 7 fixedly connected to the upper surface of the support frame 5, a control console 6 fixedly connected to the upper surface of the support frame 5 near the working plate 7, a material box 8 fixedly connected to the upper surface of the base plate 1, and a steel pipe 9 placed on the side of the working plate 7 away from the support frame 5. A bending structure 2 is provided on the side of the working plate 7 away from the support frame 5, an auxiliary structure 3 is provided on the side of the working plate 7 near both ends of the bent steel pipe 9, and a fixing structure 4 is provided on the side of the material box 8 away from the support frame 5.

[0042] The specific setup and function of its bending structure 2, auxiliary structure 3, and fixing structure 4 will be explained below.

[0043] like Figure 2 , Figure 3 and Figure 4As shown, the bending structure 2 includes a cylinder 201, which is fixedly connected to the working plate 7. A rack 202 is fixedly connected to the output end of the cylinder 201. The rack 202 has a U-shaped cross-section. A first driving tooth 203 meshes with the inner wall of the rack 202. A first driven tooth 204 meshes with the side of the first driving tooth 203 away from the rack 202. The first driven tooth 204 is rotatably connected to the working plate 7.

The second driving tooth 206 meshes with the rack 202. The first driven tooth 204 is away from the working plate. An adjusting rod 211 is fixedly connected to one side of the steel pipe 7. A second driven tooth 207 is fitted on the arc surface of the adjusting rod 211. A second driving tooth 206 meshes with the second driven tooth 207. A rotating rod 208 is fixedly connected to the upper surface of the second driven tooth 207 away from the first driven tooth 204. A connecting block 209 is fixedly connected to the end of the rotating rod 208 away from the second driven tooth 207. A fixing rod 210 is fixedly connected to the side of the connecting block 209 away from the rotating rod 208. An adjusting plate 212 is fixedly connected to the end of the adjusting rod 211 away from the first driving tooth 203. A limit rod 213 is fixedly connected to the side of the adjusting plate 212 away from the adjusting rod 211. By setting up the bending structure 2, the cylinder 201 drives the rack 202 and the gear set to achieve automatic bending of the steel pipe 9. The bending is stable and the angle is accurate, improving bending efficiency and quality. Rubber pads 214 are fixedly connected to the arc surfaces of both the fixed rod 210 and the limiting rod 213. The rubber pads 214 are adapted to the dimensions of the fixed rod 210 and the limiting rod 213. By setting the rubber pads 214, the steel pipe 9 is protected, preventing scratches and deformation during bending, and at the same time, the friction is increased to prevent the steel pipe 9 from sliding. A protective shell 215 is fitted onto the outer wall of the cylinder 201, and the protective shell 215 is adapted to the dimensions of the cylinder 201. By setting the protective shell 215, the cylinder 201 is protected, preventing impacts and dust from entering, and extending the service life of the cylinder 201. A limiting groove 216 is opened on the side of the working plate 7 near the rack 202. A limiting block 217 is slidably connected to the inner wall of the limiting groove 216, and the limiting block 217 is fixedly connected to the rack 202. By setting the limiting groove 216 and the limiting block 217, the movement of the rack 202 is guided and limited, preventing deviation and ensuring stable transmission.

[0044] The overall effect of the bending structure 2 is that, by setting the bending structure 2, the cylinder 201 drives the rack 202 and the gear set to achieve automatic bending of the steel pipe 9, with stable bending, accurate angle, and improved bending efficiency and quality.

[0045] like Figure 5 and Figure 6As shown, the auxiliary structure 3 includes a slide rail 301 with a semi-circular cross-section. The slide rail 301 is fixedly connected to the working plate 7. Two sliders 302 are slidably connected to the outer wall of the slide rail 301. A connecting rod 303 is fixedly connected to the side of each slider 302 away from the slide rail 301. A positioning rod 304 is fixedly connected to the end of each connecting rod 303 away from the slider 302. The two positioning rods 304 abut against the steel pipe 9. An adjustment groove 305 is provided on the inner wall of the slider 302. A threaded rod 306 is fixedly connected to the inner wall of the adjustment groove 305. Two limiting plates 307 are slidably connected to the inner wall of the adjustment groove 305. The two limiting plates 307 are adapted to the size of the adjustment groove 305. The threaded rod 306 is threadedly connected to the two limiting plates 307. The threaded rod 306 is a bidirectional thread. By setting the auxiliary structure 3, the support position can be adjusted according to the length of the steel pipe 9 to provide stable support for the steel pipe 9. The shape of the steel pipe 9 can also be adjusted to prevent sagging and deformation during bending. A handle 308 is fixedly connected to one end of the threaded rod 306. The handle 308 has an "L"-shaped cross-section. The handle 308 facilitates gripping and rotation, and allows for quick locking of the slider 302, improving operational convenience. Positioning blocks 309 are fixedly connected to both ends of the slide rail 301, and these blocks are also fixedly connected to the work plate 7. The positioning blocks 309 limit the movement range of the slider 302, preventing it from sliding off the slide rail 301 and improving safety.

[0046] The overall effect of the auxiliary structure 3 is that, by setting the auxiliary structure 3, the support position can be adjusted according to the length of the steel pipe 9 to provide stable support for the steel pipe 9, and the shape of the steel pipe 9 can be adjusted to prevent sagging and deformation when bending.

[0047] like Figure 7 and Figure 8As shown, the fixing structure 4 includes a motor 401, which is fixedly connected to the base plate 1. An adjusting block 402 is fixedly connected to the upper surface of the base plate 1. A square groove 403 is formed on the inner wall of the adjusting block 402. A lead screw 406 is fixedly connected to the inner wall of the square groove 403. The lead screw 406 is fixedly connected to the output end of the motor 401. A fixing block 404 is fixedly connected to the arc surface of the lead screw 406. Two guide blocks 405 are threadedly connected to the arc surface of the lead screw 406. The square groove 403 is adapted to the size of the two guide blocks 405. A connecting rod 407 is fixedly connected to the side of each guide block 405 away from the square groove 403. A clamping block 408 is fixedly connected to the end of each connecting rod 407 away from the guide block 405. By setting up the fixing structure 4, the motor 401 drives the lead screw 406 to drive the clamping block 408 to automatically clamp the material box 8, thereby clamping and fixing the material box 8 and preventing vibration and displacement during the material collection process. A sponge pad 409 is fixedly connected to one side of each of the two clamping blocks 408 that are close to each other. The size of the sponge pad 409 is adapted to that of the clamping block 408. By setting the sponge pad 409, the surface of the material box 8 is protected, preventing damage to the material box 8. A guide groove 411 is opened on the upper surface of the base plate 1. Two auxiliary blocks 410 are slidably connected to the inner wall of the guide groove 411. The two auxiliary blocks 410 are fixedly connected to the two clamping blocks 408. By setting the guide groove 411 and the auxiliary blocks 410, the clamping blocks 408 are guided and limited, ensuring that the clamping action is smooth and reliable.

[0048] The effect achieved by the entire fixing structure 4 is that, by setting the fixing structure 4, the motor 401 drives the lead screw 406 to drive the clamping block 408 to automatically clamp the material box 8, thereby clamping and fixing the material box 8 and preventing vibration and displacement during the material collection process.

[0049] The overall working principle is as follows: When bending the steel pipe 9 is required, the steel pipe 9 is first placed on the surface of the working plate 7, so that the steel pipe 9 abuts against the fixed rod 210, the adjusting rod 211 and the limiting rod 213. The rubber pads 214 on the surfaces of the fixed rod 210 and the limiting rod 213 increase the contact friction and prevent the steel pipe 9 from sliding or deviating during the bending process. At the same time, the rubber pads 214 protect the surface of the steel pipe 9 from scratches and deformation. Then, the cylinder 201 inside the protective shell 215 is activated, so that the cylinder 201 drives the U-shaped rack 202 to move telescopically. The rack 202 slides along the limiting groove 216 inside the working plate 7 through the limiting block 217, which limits and guides the movement trajectory of the rack 202 to prevent the rack 202 from deviating during operation. The rack 202 moves, and then simultaneously engages the first driving tooth 203 and the second driving tooth 206 to rotate. The first driving tooth 203 drives the first driven tooth 204 to rotate, and the second driving tooth 206 drives the second driven tooth 207 to rotate synchronously. The first driven tooth 204 drives the adjusting rod 211 to rotate, so that the adjusting plate 212 at the end of the adjusting rod 211 and the limiting rod 213 limit and position the steel pipe 9. The second driven tooth 207 drives the fixed rod 210 to swing through the rotating rod 208 and the connecting block 209. Finally, the fixed rod 210, the adjusting rod 211 and the limiting rod 213 cooperate to squeeze the steel pipe 9, completing the automated bending operation of the steel pipe 9, and achieving the effects of accurate bending angle, stable bending process and high processing efficiency.

[0050] When it is necessary to perform bending auxiliary support on steel pipe 9 and fix material box 8, first rotate L-shaped handle 308 to drive threaded rod 306 to rotate, so that threaded rod 306 releases the locking limit of two limiting plates 307 inside adjusting groove 305. Then, according to the actual length of steel pipe 9, slide two sliders 302 on the surface of slide rail 301. Slider 302 drives positioning rod 304 to move to a suitable support position through connecting rod 303. Positioning blocks 309 at both ends of slide rail 301 limit the sliding limit position of slider 302 to prevent slider 302 from falling off slide rail 301. Next, rotate handle 308 to drive threaded rod 306 to reverse, so that two limiting plates 307 move closer to each other and lock slider 302, so that two positioning rods 304 stably support steel pipe 9 and prevent drooping deformation when steel pipe 9 is bent, thus completing the auxiliary positioning operation of steel pipe 9.

[0051] When it is necessary to clamp and fix the material box 8, the start motor 401 drives the lead screw 406 inside the square groove 403 of the adjusting block 402 to rotate. The lead screw 406 drives the two guide blocks 405 to move relative to each other. The guide blocks 405 drive the clamping block 408 to move through the connecting rod 407. The auxiliary block 410 inside the guide groove 411 of the base plate 1 slides and guides the clamping block 408 to ensure that the clamping block 408 moves smoothly. Finally, the sponge pads 409 on the inner side of the two clamping blocks 408 fit and clamp the material box 8, buffering the clamping pressure and preventing damage to the material box 8, thus achieving the effect of fixing the material box 8 to prevent vibration and displacement during the processing.
