Technical Field
[0001] This utility model belongs to the field of automotive parts processing technology, specifically relating to an arc bending device for automotive parts. Background Technology
[0002] In automotive parts manufacturing, a large number of sheet metal components (such as bumper beams, brackets, and trim strips) need to be processed into specific arc shapes to meet structural, assembly, or aesthetic requirements. Currently, there are two main methods for processing such workpieces by arc bending: one is to use a regular bending machine for segmented bending, and the other is to use a special arc-shaped stamping die for one-time forming.
[0003] When processing automotive parts, existing arc bending devices lack sufficient bending stability. During the bending process, the parts are prone to positional movement and tilting, which reduces the arc bending accuracy of the automotive parts and also reduces the processing efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide an arc bending device for automotive parts, which aims to solve the problem that the existing arc bending devices are not stable enough for bending automotive parts, and are prone to positional movement and tilting during the bending process, resulting in reduced arc bending accuracy of automotive parts and reduced processing efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An arc bending device for an automotive part, comprising:
[0007] Base;
[0008] A support frame is fixedly connected to the upper end of the base, a mounting bracket is fixedly connected to the upper end of the support frame, and a processing plate is fixedly connected to the upper end of the support frame.
[0009] Bending mechanism, the bending mechanism comprising:
[0010] Mounting base, the mounting base is fixedly connected to the upper inner wall of the mounting frame, a sealing plate is slidably connected to the inner surface of the mounting base, a second motor is fixedly connected to the upper end of the sealing plate, and the output end of the second motor movably passes through the lower end of the sealing plate;
[0011] A rotating rod, the upper end of which movably penetrates the lower inner wall of the mounting base, and the lower end of which is fixedly connected to a rotating seat, the lower end of which is rotatably connected to two bent columns, each of which has a protective sleeve fitted on its outer surface; and
[0012] A transmission assembly, which is disposed within a mounting base to enable rotation of the rotating rod.
[0013] As a preferred embodiment of this utility model, the transmission assembly includes:
[0014] The driving gear is fixedly connected to the upper end of the rotating rod. The output end is fixedly connected to the upper end of the driving gear. Multiple driven gears are rotatably connected to the lower end of the sealing plate. The driving gear and multiple driven gears mesh with each other. A gear ring is rotatably connected to the inner surface of the mounting base. The gear ring meshes with multiple driven gears.
[0015] In a preferred embodiment of this utility model, a first motor is fixedly connected to the upper end of the support frame, and rotating shafts are fixedly connected to both output ends of the first motor. The far ends of the two rotating shafts respectively movably pass through both ends of the support frame.
[0016] As a preferred embodiment of this utility model, it further includes two sets of clamping mechanisms, each set of clamping mechanisms comprising:
[0017] A rotating plate is fixedly connected to one end of a rotating shaft. One end of the rotating plate is rotatably connected to two arc-shaped plates via the rotating shaft. One end of each of the two arc-shaped plates is rotatably connected to two connecting plates via the rotating shaft. The upper ends of the two connecting plates movably penetrate the upper end of the support frame.
[0018] Two clamping seats are fixedly connected to the upper ends of two connecting plates, and clamping pads are provided on the inner surfaces of both clamping seats.

[0022] As a preferred embodiment of this utility model, a support seat is fitted on the circumferential surface of each of the two rotating shafts, and the upper ends of the two support seats and the upper end of the support frame are fixedly connected.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] 1. In this solution, by starting the drive source, the rotation of the driving gear drives multiple driven gears to rotate. The driven gears mesh with the fixed gear ring, thereby generating a revolution motion, which is ultimately synthesized and output as a slow rotation of the sealing plate and the rotating rod. The rotating rod drives two bending columns with protective sleeves to rotate through the rotating seat, applying pressure to the edge of the workpiece, making it continuously and uniformly bent into a predetermined arc shape. This improves the bending stability of the arc bending device for automotive parts, avoids positional movement and tilting during the bending process, enhances the arc bending accuracy of automotive parts, and improves the processing efficiency of automotive parts.
[0025] 2. In this solution, the first motor is started to drive the rotating shafts on both sides to rotate synchronously. Through the linkage mechanism composed of the rotating plate, the arc plate, and the connecting plate, the rotational motion is converted into the opposing linear motion of the two clamping seats. The clamping seats move smoothly under the constraint of the limiting block and the limiting groove, and finally the workpiece is reliably clamped and fixed by the clamping pad.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Example 1
[0035] Please see Figure 1-5 The present invention provides the following technical solution:
[0036] An arc bending device for an automotive part, comprising:
[0037] Base 1;
[0038] Support frame 2 is fixedly connected to the upper end of base 1. Mounting frame 3 is fixedly connected to the upper end of support frame 2. Processing plate 4 is fixedly connected to the upper end of support frame 2.
[0039] Bending mechanism, the bending mechanism includes:
[0040] Mounting base 20 is fixedly connected to the upper inner wall of mounting frame 3. A sealing plate 16 is slidably connected to the inner surface of mounting base 20. A second motor 8 is fixedly connected to the upper end of sealing plate 16. The output end of the second motor 8 movably passes through the lower end of sealing plate 16.
[0041] A rotating rod 21 has its upper end movably penetrating the lower inner wall of the mounting base 20. A rotating seat 22 is fixedly connected to the lower end of the rotating rod 21. Two bent pillars 23 are rotatably connected to the lower end of the rotating seat 22, and protective sleeves 24 are fitted onto the outer surfaces of both bent pillars 23.
[0042] A transmission assembly is disposed within the mounting base 20 to enable rotation of the rotating rod 21.
[0043] In a specific embodiment of this utility model, the base 1 provides a stable foundation and mounting platform for the entire device, ensuring the equipment remains stable during operation. The support frame 2, as the main load-bearing structure, is fixedly connected to the base 1 and is used to support and install other upper-level components. The mounting frame 3 is fixed to the support frame 2 and is used to suspend and fix the mounting seat 20 of the bending mechanism, determining its spatial position. The processing plate 4 is fixed to the support frame 2, providing a flat worktable for placing and positioning the automotive parts to be bent. The mounting seat 20 is fixed to the mounting frame 3, forming a sealed box for accommodating and supporting the transmission components. Providing installation space and protection, the sealing plate 16 slides on the inner surface of the mounting base 20 to seal the upper opening of the mounting base 20, preventing contaminants from entering. It also serves as the mounting base for the second motor 8 and the driven gear 18. The second motor 8 is fixed to the upper end of the sealing plate 16, and its output end penetrates downwards through the sealing plate 16, providing initial rotational power to drive the transmission assembly. The upper end of the rotating rod 21 penetrates the bottom of the mounting base 20 and connects to the transmission assembly, while the lower end connects to the rotating seat 22, thereby transmitting the rotational motion generated by the transmission assembly downwards. The rotating seat 22 is fixed to the lower end of the rotating rod 21 for mounting and connecting... Two bending columns 23 are connected, rotating at the lower end of the rotating seat 22. Their function is to directly contact the workpiece and apply pressure to the workpiece through rotation to bend it into shape. A protective sleeve 24 is fitted on the outer surface of the bending column 23 to prevent direct wear of the bending column 23 and to avoid scratching the surface of the workpiece during bending. The driving gear 17 is fixed to the upper end of the rotating rod 21 and connected to the output end of the second motor 8, thereby receiving power and driving the driven gear 18 to move. The driven gear 18 rotates at the lower end of the sealing plate 16 and meshes with the driving gear 17 and the gear ring 19, realizing the rotation and revolution under the drive of the driving gear 17. The combined motion of rotation drives the sealing plate 16 and the rotating rod 21 to rotate. According to the meshing of the driven gear 18 of the gear ring 19, the motion trajectory of the driven gear 18 is constrained, causing it to revolve. This improves the bending stability of the arc bending device for automobile parts, avoids positional movement and tilting during the bending process, enhances the arc bending accuracy of automobile parts, and improves the processing efficiency of automobile parts. It should be noted that the specific model of the second motor 8 used shall be selected by those skilled in the art, and the above-mentioned second motor 8, etc., are all existing technologies, which will not be elaborated in this solution.
[0044] Please refer to the details. Figure 5 The transmission components include:
[0045] The driving gear 17 is fixedly connected to the upper end of the rotating rod 21. The output end of the second motor 8 is fixedly connected to the upper end of the driving gear 17. The lower end of the sealing plate 16 is rotatably connected to multiple driven gears 18. The driving gear 17 and multiple driven gears 18 are all meshed. The inner surface of the mounting base 20 is rotatably connected to a gear ring 19. The gear ring 19 and multiple driven gears 18 are all meshed.
[0046] In this embodiment: the driving gear 17 is fixed to the upper end of the rotating rod 21 and connected to the output end of the second motor 8, thereby receiving power and driving the driven gear 18 to move. The driven gear 18 rotates at the lower end of the sealing plate 16 and meshes with the driving gear 17 and the gear ring 19, realizing a compound motion of rotation and revolution under the drive of the driving gear 17, thereby driving the sealing plate 16 and the rotating rod 21 to rotate. According to the meshing of the gear ring 19 with the driven gear 18, the motion trajectory of the driven gear 18 is constrained, causing it to revolve.
[0047] Please refer to the details. Figure 2 The upper end of the support frame 2 is fixedly connected to the first motor 5, and the output ends of the first motor 5 are fixedly connected to the rotating shafts 6. The far ends of the two rotating shafts 6 respectively move through the two ends of the support frame 2.
[0048] In this embodiment: the first motor 5 is fixed to the upper end of the support frame 2, and its function is to provide driving force for the opening and closing action of the clamping mechanism. The rotating shaft 6 is fixedly connected to the output end of the first motor 5, and its function is to transmit the rotational power of the first motor 5 to the clamping mechanisms on both sides.
[0049] Please refer to the details. Figure 3 and Figure 4 It also includes two sets of clamping mechanisms, each set of clamping mechanisms including:
[0050] Rotating plate 13 is fixedly connected to one end of rotating shaft 6. One end of rotating plate 13 is rotatably connected to two arc-shaped plates 14 through rotating shaft. One end of each of the two arc-shaped plates 14 is rotatably connected to two connecting plates 15 through rotating shaft. The upper ends of the two connecting plates 15 movably pass through the upper end of support frame 2.
[0051] Two clamping seats 11 are fixedly connected to the upper ends of two connecting plates 15 respectively, and clamping pads 12 are provided on the inner surface of each clamping seat 11.
[0052] A limiting component is provided inside the support frame 2 to limit the movement of the two sliding clamps 11.
[0053] In this embodiment: the rotating plate 13 is fixed to one end of the rotating shaft 6, converting the rotational motion of the rotating shaft 6 into its own oscillation. The arc plate 14 is connected to the rotating plate 13 and the connecting plate 15 respectively through the rotating shaft, forming a linkage mechanism, which converts the oscillation of the rotating plate 13 into the approximately linear motion of the connecting plate 15. The connecting plate 15 guides the motion and force transmitted from the arc plate 14 to the clamping seat 11. The clamping seat 11 is equipped with the clamping pad 12 and directly performs the action of clamping or releasing the workpiece. The clamping pad 12 directly contacts the workpiece, providing friction to clamp the workpiece, while avoiding the metal clamping seat 11 from scratching the surface of the workpiece. The limiting groove 9 is opened at the upper end of the support frame 2. Its function is to accommodate and guide the limiting block 10, restrict the movement path of the clamping seat 11, ensure that the clamping seat 11 moves along the trajectory specified by the limiting groove 9, and prevent it from deviating. It should be noted that the specific model of the second motor 8 used can be selected by those skilled in the art, and the above-mentioned second motor 8, etc., are all prior art, and this solution will not elaborate on them.
[0054] Please refer to the details. Figure 3 Each set of limit components includes:
[0055] The limiting groove 9 is opened at the upper end of the support frame 2. Two limiting blocks 10 are slidably connected to the inner surface of the limiting groove 9. The upper ends of the two limiting blocks 10 and the lower ends of the two clamping seats 11 are fixedly connected respectively.
[0056] In this embodiment, the limiting groove 9 is provided on the upper end of the support frame 2. Its function is to accommodate and guide the limiting block 10, restrict the movement path of the clamping seat 11, ensure that the clamping seat 11 moves along the trajectory specified by the limiting groove 9, and prevent it from deviating.
[0057] Please refer to the details. Figure 2 Support seats 7 are fitted on the circumferential surfaces of the two rotating shafts 6, and the upper ends of the two support seats 7 are fixedly connected to the upper end of the support frame 2.

Its function is to provide additional radial support for the rotating shaft 6 and increase its rigidity and stability during rotation.
[0059] The working principle and usage process of this utility model are as follows: The workpiece to be bent is placed on the processing plate 4 and initially positioned. Then, the first motor 5 is started, driving the rotating shafts 6 on both sides to rotate synchronously. Through the linkage mechanism composed of the rotating plate 13, the arc plate 14 and the connecting plate 15, the rotational motion is converted into the opposing linear motion of the two clamping seats 11. Finally, the workpiece is reliably clamped and fixed by the clamping pad 12. Then, the second motor 8 is started, driving the active gear 17 to rotate and driving multiple driven gears 18 to rotate. The driven gears 18 mesh with the fixed gear ring 19, thereby generating a revolution motion. Finally, the combined motion is output as the slow rotation of the sealing plate 16 and the rotating rod 21. The rotating rod 21 drives the two bending columns 23 covered with protective sleeves 24 to rotate through the rotating seat 22, applying pressure to the edge of the workpiece, so that it is continuously and evenly bent into a predetermined arc shape. After the bending is completed, the second motor 8 stops, the first motor 5 reverses, and drives the clamping mechanism to release the workpiece. The operator can then remove the formed part and complete the processing cycle.
[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
