Description

Technical Field

[0001] This utility model relates to the field of pipe bending mechanisms, and in particular to a pipe bending mechanism for automotive structural components. Background Technology

[0002] The tube bending mechanism for automotive structural components is a specialized machine tool used to precisely bend metal tubes into complex shapes required for structural components such as automotive chassis and roll cages.

[0003] Existing technologies, such as the utility model with announcement number CN219561019U, disclose a pipe bending processing mechanism. The key technical points of the mechanism are: it includes a pipe bending assembly, a positioning groove on one side of the pipe bending assembly, and a push rod on the side of the positioning groove away from the pipe bending assembly. The push rod can move axially. When the pipe is placed in the positioning groove, the push rod pushes the pipe to the pipe bending assembly for bending processing. This utility model increases the efficiency and stability of pipe bending processing.

[0004] Regarding the above-mentioned issues, the following technical defects were found: Existing pipe bending mechanisms mostly rely on manual feeding and positioning of pipe fittings, which not only results in low production efficiency but also makes it difficult to achieve continuous batch processing. Furthermore, the pipe bending mechanisms of traditional equipment are often designed for specific pipe diameters, making it difficult to quickly adapt to pipe fittings of different sizes, thus limiting the processing range and resulting in poor equipment versatility.

[0005] Therefore, it is particularly important to develop a new type of pipe bending mechanism for automotive structural components to overcome the above-mentioned technical limitations. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1 and Figure 2 This utility model provides a pipe bending mechanism for automotive structural components, comprising: a workbench 1 and a pipe body 8. A rotating shaft 2 is rotatably connected to the upper surface of the workbench 1. A drive module for driving the rotating shaft 2 to rotate is provided inside the workbench 1. A turntable 5 is fixedly connected to the arc surface of the rotating shaft 2. A rotating seat 6 is fixedly connected to the arc surface of the rotating shaft 2. An extrusion wheel 7 is rotatably connected to the inner wall of the rotating seat 6. An adjustment structure 3 is provided on one side of the workbench 1. An auxiliary structure 4 is provided on the upper surface of the workbench 1.

[0033] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The adjustment structure 3 includes a support plate 301. One side of the support plate 301 is fixedly connected to the worktable 1. A cylinder 302 is fixedly connected to the upper surface of the support plate 301. A slider 303 is fixedly connected to the output end of the cylinder 302. A limit frame 305 is fixedly connected to the upper surface of the slider 303. One side of the pipe body 8 is in contact with one side of the inner wall of the limit frame 305. Both sides of the limit frame 305 are provided with sliding grooves 306. Two clamping plates 307 are slidably connected to the inner wall of the sliding grooves 306. A lead screw 309 is threaded through the surface of the two clamping plates 307. The arc surface of the lead screw 309 is provided with bidirectional threads. A partition plate 308 is fixedly connected to one side of the limit frame 305. The partition plate 308 is rotatably connected to the lead screw 309. A welding plate 310 is fixedly connected to the upper surface of the limit frame 305. A servo motor 311 is fixedly connected to one side of the welding plate 310. The output end of the servo motor 311 is fixedly connected to one end of the lead screw 309. By setting the adjustment structure 3, when using the bending mechanism to bend pipes for automotive structural components, the feeding of the pipes can be performed automatically, and pipes of different sizes can be clamped and positioned, effectively improving processing efficiency and enhancing the versatility and practicality of the equipment. A slide rail 304 is fixedly connected to the upper surface of the worktable 1, and the inner wall of the slide rail 304 is slidably connected to the slider 303. When the cylinder 302 drives the slider 303 to move, the slider 303 slides along the inner wall of the slide rail 304, thereby improving the stability of the slider 303 driving the limit frame 305 to move. Rubber pads 312 are fixedly connected to the sides of the two clamping plates 307 that are close to each other, and the size of the rubber pads 312 is adapted to one side of the clamping plate 307. The rubber pads 312 can increase the friction between the clamping plate 307 and the pipe body 8, thereby improving the limiting effect of the clamping plate 307 on the pipe body 8. Guide rods 313 are slidably inserted through the surfaces of the two clamping plates 307, and both ends of the guide rods 313 are fixedly connected to one side of the limiting frame 305. As the clamping plates 307 move along the inner wall of the slide groove 306, they also move along the arc surface of the guide rods 313, thereby improving the stability of the movement of the clamping plates 307.

[0034] In the embodiments of this utility model, please refer to Figure 5The auxiliary structure 4 includes a threaded rod 41, the lower surface of which is rotatably connected to the upper surface of the worktable 1. An adjusting plate 42 is threadedly connected to the arc surface of the threaded rod 41. The adjusting plate 42 has an "L"-shaped cross-section. A toothed block 43 is fixedly connected to the lower surface of the short arm end of the adjusting plate 42. A connecting plate 44 is fixedly connected to the upper end of the rotating shaft 2. A toothed hole 45 is provided on the connecting plate 44 corresponding to the position of the toothed block 43, and the size of the toothed hole 45 matches that of the toothed block 43. By setting the auxiliary structure 4, the extrusion roller 7 can be locked when the bending mechanism is not in use, thus preventing accidental rotation of the extrusion roller 7 due to accidental contact or equipment inertia. This enhances equipment safety and maintains processing accuracy. A driven bevel gear 47 is fixedly connected to the arc surface of the threaded rod 41. A drive motor 49 is fixedly connected to the upper surface of the worktable 1. A driving bevel gear 48 is fixedly connected to the output end of the drive motor 49, and the driving bevel gear 48 meshes with the driven bevel gear 47. When it is necessary to control the rotation of the threaded rod 41, the drive motor 49 is first started to drive the active bevel gear 48 to rotate. The active bevel gear 48 drives the driven bevel gear 47 to rotate, and the driven bevel gear 47 drives the threaded rod 41 to rotate. By setting the above structure, the effect of automatically controlling the rotation of the threaded rod 41 is achieved. A limiting rod 46 is slidably inserted through the surface of the long arm end of the adjusting plate 42. The lower end of the limiting rod 46 is fixedly connected to the upper surface of the worktable 1. During the lifting and lowering process of the adjusting plate 42, the limiting rod 46 can guide and position it, thereby preventing the adjusting plate 42 from rotating or deviating during the lifting and lowering process.

[0035] The working principle of the tube bending mechanism for automotive structural components provided by this utility model is as follows: When the tube bending mechanism is needed to bend the tube for automotive structural components, first insert the tube body 8 into the limiting frame 305, then start the servo motor 311 to drive the lead screw 309 to rotate. The lead screw 309 drives the two clamping plates 307, causing the two clamping plates 307 to move towards each other along the inner wall of the slide groove 306. When the clamping plates 307 drive the rubber pad 312 to abut against the tube body 8, the operation of the servo motor 311 can be stopped. Then, start the cylinder 302 to drive the slider 303, causing the slider 303 to move along the inner wall of the slide rail 304 and drive the limiting frame 305 and the tube body 8 towards the limiting wheel, so that the position to be bent of the tube body 8 is placed between the turntable 5 and the extrusion wheel 7. When the tube body 8 moves to the appropriate position, the operation of the cylinder 302 can be stopped. Then, start the drive module inside the worktable 1 to control the rotating shaft 2. The rotating shaft 2 drives the rotating seat 6 and the extrusion wheel 7 to rotate, causing the extrusion wheel 7 to extrude the pipe body 8. After the pipe body is extruded and formed, the servo motor 311 is started to drive the lead screw 309 to reverse. The lead screw 309 drives the two clamping plates 307 to move away from each other at the same time. When the clamping plates 307 and the rubber pad 312 are separated from the pipe body 8, the limitation on the pipe body 8 can be released. When the cylinder 302 drives the slider 303 to move, the slider 303 will slide along the inner wall of the slide rail 304, thereby improving the stability of the slider 303 driving the limit frame 305 to move. In addition, the rubber pad 312 can increase the friction between the clamping plate 307 and the pipe body 8, thereby improving the limitation effect of the clamping plate 307 on the pipe body 8. Finally, while the clamping plate 307 moves along the inner wall of the slide groove 306, it will also move along the arc surface of the guide rod 313, thereby improving the stability of the movement process of the clamping plate 307.

[0036] When the bending mechanism is not in use, the drive motor 49 can be started to drive the active bevel gear 48 to rotate. The active bevel gear 48 drives the driven bevel gear 47 to rotate. The driven bevel gear 47 drives the threaded rod 41 to rotate. The threaded rod 41 drives the adjusting plate 42, causing the adjusting plate 42 to move the toothed block 43 downward. When the toothed block 43 is inserted into the toothed hole 45, the rotating shaft 2 can be locked, and the extrusion wheel 7 can be locked. When it is necessary to unlock the extrusion wheel 7, the drive motor 49 is started to drive the active bevel gear 48 to rotate in the opposite direction. The active bevel gear 48 drives the driven bevel gear 47 to rotate in the opposite direction. The driven bevel gear 47 drives the threaded rod 41 to rotate in the opposite direction. The threaded rod 41 drives the adjusting plate 42 to move in the opposite direction, causing the adjusting plate 42 to move the toothed block 43 upward. When the toothed block 43 separates from the toothed hole 45, the locking of the rotating shaft 2 and the extrusion wheel 7 can be released.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
