Description

Technical Field

[0001] This utility model relates to the field of precision machinery manufacturing and forming technology, and in particular to a tube bending device. Background Technology

[0002] In the current era of rapid development in the new energy vehicle industry, the battery pack, as the core energy source of new energy vehicles, directly affects the vehicle's range, safety, and lifespan through its heat dissipation performance. Coolant pipes, as a key component of the battery pack's thermal management system, play a crucial role in timely dissipating the heat generated during battery operation. To accommodate the complex internal structure of the battery pack, coolant pipes often need to be bent into specific shapes to achieve efficient spatial layout and heat exchange efficiency. Therefore, the precision and reliability of the pipe bending process have a significant impact on the overall performance of the battery pack.

[0003] Currently, the bending of battery pack coolant pipes largely relies on traditional bending equipment or manual operation. Traditional bending equipment typically uses fixed dies to bend the pipes. While it can achieve basic bending functions, it has poor adaptability to pipes of different diameters, bending angles, and complex bending paths. When processing pipes of different specifications, frequent die changes are required, which not only increases production preparation time and reduces production efficiency but also increases equipment investment costs.

[0004] In actual production, battery pack coolant pipelines often require multiple bends at different angles, and the bending radius must be strictly controlled to avoid problems such as wrinkles, cracks, or excessive deformation of the pipelines. Otherwise, serious consequences such as coolant leakage and reduced heat dissipation efficiency may occur. However, existing bending equipment often suffers from insufficient positioning accuracy when performing multi-segment bends. The fixed limiting structure of traditional equipment makes it difficult to flexibly adjust the limiting position according to the pipeline material, diameter, and bending requirements, which can easily cause deviations in the pipeline bending angle and affect the assembly accuracy of the pipeline with other components inside the battery pack.

[0005] Meanwhile, existing bending devices lack sufficient stability in pipe positioning during secondary or complex bending operations, making them prone to slippage and resulting in reduced bending dimensional accuracy. Although some equipment has certain adjustment functions, the adjustment process is cumbersome and difficult to quickly adapt to the bending requirements of different pipe specifications, severely restricting the mass production efficiency and quality consistency of battery pack coolant pipes.

[0006] Furthermore, for coolant pipes requiring multi-angle bending, traditional equipment typically necessitates multiple clamping and positioning operations. This not only increases the number of steps but can also affect the final bending accuracy due to accumulated errors from multiple positioning attempts. Therefore, developing a bending device capable of precise positioning, flexible adjustment, and adaptability to the multi-section bending requirements of various pipe specifications is of great significance for improving the processing quality and production efficiency of battery pack coolant pipes.

[0037] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0038] like Figures 1 to 7As shown in the figure, the present invention provides a pipe bending device, including a base plate 100, a linear limiting bending device 300 and an adjusting device 400. In this embodiment, the base plate 100 is configured as a disc-shaped structure, and a center limiting device 200 is provided at the center position of the base plate 100. The center limiting device 200 can limit the position of a part of the pipe at the center position of the disc base plate 100, which facilitates bending of the pipe.

[0039] A rotating groove 110 is provided on the base plate 100 corresponding to the center limiting device 200. The rotating groove 110 is located at the center of the base plate 100, so that the center limiting device 200 is located in the rotating groove 110. The center limiting device 200 includes a rotating block 210 and a first limiting rod 220. The rotating block 210 is a cylindrical structure, and the rotating groove 110 is also a cylindrical structure. Both have the same radius, so that the rotating block 210 can be installed in the rotating groove 110 and rotate in the rotating groove 110.

[0040] In this embodiment, the rotation of the rotating groove 110 is driven by a motor. The motor is located on the opposite side of the base plate 100, and the output end of the motor extends into the rotating groove 110 and is fixedly connected to the rotating block 210, so that when the motor is driven, the motor can drive the rotating block 210 to rotate in the rotating groove 110.

[0041] Preferably, in this embodiment of the application, the motor is configured as a servo motor.

[0042] A first limiting rod 220 is provided on the rotating block 210. There are multiple first limiting rods 220 on the rotating block 210, specifically three. All three first limiting rods 220 are fixedly connected to the rotating block 210.

[0043] The first limiting rod 220 is located on the side of the rotating block 210 away from the rotating groove 110, so that the pipe can be limited by the first limiting rod 220. Since there are multiple first limiting rods 220, a clamping part 230 is formed between the multiple first limiting rods 220 for convenient limiting. The clamping part 230 can clamp the pipe and prevent the pipe from moving.

[0044] In the above, the limiting is achieved by multiple first limiting rods 220. The position of the first limiting rods 220 can be adjusted according to the pipe diameter. The adjustment is achieved by the rotation of the rotating block 210 driven by the motor. When the rotating block 210 rotates to a certain position, the first limiting rods 220 cooperate with the linear limiting bending device 300 to limit the pipe.

[0045] In the above, the distances of the multiple first limit rods 220 from the center of the rotating block 210 are not the same.

[0046] Two linear limiting bending devices 300 are provided, and the two linear limiting bending devices 300 are respectively located on both sides of the rotating block 210. An adjustment groove 120 is provided on the base plate 100 corresponding to the position of the linear limiting bending device 300. The adjustment groove 120 is linearly arranged on the base plate 100, and the two adjustment grooves 120 are arranged parallel to each other. The linear limiting bending device 300 includes a limiting slider 310, which is located in the adjustment groove 120, so that the limiting slider 310 can move linearly in the direction of the adjustment groove 120 within the adjustment groove 120.

[0047] A second limiting rod 320 is provided on the limiting slider 310. The second limiting rod 320 can cooperate with the first limiting rod 220 on the central limiting device 200 to bend the pipe. The bending process is a single bending process.

[0048] The cooperation of the center limiting device 200 and the linear limiting bending device 300 can bend straight pipes. The bending process is carried out by the linear limiting bending device 300. A driving member 330 is provided in the adjustment groove 120. The fixed end of the driving member 330 is connected to the inner wall of the adjustment groove 120, and the output end of the driving member 330 is fixedly connected to the limiting slider 310. Driving the driving member 330 can cause the limiting slider 310 to move within the adjustment groove 120.

[0049] In this embodiment, the driving component 330 is configured as a hydraulic cylinder or an electric push rod.

[0050] An adjustment device 400 is also provided on the base plate 100. The adjustment device 400 mainly includes a limiting component, which is a sliding block 410. An annular groove 130 is provided on the base plate 100 at the position corresponding to the adjustment device 400. In order to facilitate the bending of the pipe, the annular groove 130 is set as a semi-circular structure, and the semi-circular structure is located on one side of the adjustment groove 120.

[0051] The center of the annular groove 130 is at the same position as the center of the rotating block 210.

[0052] Limiting blocks 440 are provided at both ends of the sliding block 410 disposed in the annular groove 130. In this application, the limiting blocks 440 are set as limiting plates. The limiting plates are connected to the sliding block 410 by locking bolts 430. When the sliding block 410 is placed in the annular groove 130, the bottom plate 100 is positioned between the two limiting plates by locking bolts 430, so that the sliding block 410 can move in the annular groove 130 by the limiting action of the limiting plates.

[0053] A third limiting rod 420 is provided on the sliding block 410. The third limiting rod 420, like the first limiting rod 220 and the second limiting rod 320, limits the bending of the pipeline.

[0054] When the pipe is bent, a scale is provided at the edge of the annular groove 130. When the third limiting rod 420 on the sliding block 410 limits the pipe, the pipe can be bent a second time by moving the sliding block 410 in the annular groove 130.

[0055] To facilitate the bending of the pipe by the sliding block 410, an adjusting rod 500 is also provided in this embodiment. One end of the adjusting rod 500 is rotatably connected to the base plate 100. The adjusting rod 500 is connected to the sliding block 410. When the adjusting rod 500 rotates, it drives the sliding block 410 to move within the annular groove 130.

[0056] Specifically, a fixing hole 510 is provided on the adjusting rod 500 corresponding to the position of the sliding block 410, and the locking bolt 430 can be located in the fixing hole 510. When the adjusting rod 500 rotates around the base plate 100, the adjusting rod 500 can drive the sliding block 410 to move in the annular groove 130.

[0057] Preferably, such as Figure 7 As shown in the embodiment of this application, there may be two annular grooves 130, and the two annular grooves 130 have different radii. The adjusting rod 500 can connect and rotate the sliding block 410 in one of the annular grooves 130.

[0058] Furthermore, such as Figure 7 As shown, a fourth limiting rod 520 can be provided at the end of the adjusting rod 500 away from the base plate 100. The fourth limiting rod 520 is the same as the third limiting rod 420 and can limit the bending of the pipeline.

[0059] Meanwhile, a handle 530 is provided on the adjusting rod 500, which allows the adjusting rod 500 to be rotated easily.

[0060] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
