[0002] In a motorcycle fuel tank, copper tubing, as a component of the fuel system, plays a crucial role in delivering fuel from the tank to the engine. In carburetors or fuel injection systems, copper tubing connects the fuel tank, fuel pump, and engine, ensuring a stable fuel supply. Due to the structural layout of motorcycles, copper tubing often needs to be bent multiple times to bypass the frame and ensure a compact installation. Therefore, it requires bending processing before assembly.

[0003] For example, Chinese patent "CN217749089U" discloses "a pipe bending tool," which can reduce the labor intensity of workers, improve work efficiency, make construction operations efficient and safe, and at the same time improve the pipe bending qualification rate and reduce material waste. However, the above-mentioned bending tool can only bend pipes smaller than the arc-shaped bend. When processing pipes of other sizes, it is necessary to customize other bending tools, which is not very applicable. Utility Model Content

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] This utility model embodiment proposes a convenient bending tool for oil tank copper tubes, used for bending the copper tube body 1. It includes a shaping wheel 3, a limiting seat 5 disposed on the shaping wheel 3, and a pressing block 2 that moves circumferentially along the shaping wheel 3. The limiting seat 5 has a limiting groove 501. The copper tube body 1 is located between the shaping wheel 3 and the pressing block 2 and is within the limiting groove 501. It also includes an adjusting component connected between the shaping wheel 3 and the pressing block 2, used to adjust the distance between the pressing block 2 and the axis of the shaping wheel 3.

[0028] In the embodiments of this utility model, such as Figure 3 As shown, before processing, the copper tube body 1 is initially positioned in a straight line. To facilitate placing the copper tube body 1 between the limiting groove 501, the shaping wheel 3, and the pressing block 2, the pressing block 2 is adjusted upwards, allowing the copper tube body 1 to pass through the limiting groove 501 and be positioned between the shaping wheel 3 and the pressing block 2. When bending the copper tube body 1, the pressing block 2 is moved, causing it to move circumferentially along the shaping wheel 3, thereby achieving the bending of the copper tube body 1. After bending, the copper tube body 1... Figure 2 As shown.

[0029] Secondly, if the size of the copper tube to be processed changes, the distance between the pressing block 2 and the shaping wheel 3 can be adjusted by the adjusting component. This adjusts the bending space between the pressing block 2 and the shaping wheel 3, allowing it to accommodate copper tube bodies 1 of different diameters. It is no longer limited by fixed-shape or-sized bends, reducing tool change frequency and improving versatility. The adjusting component can be any telescopic rod structure, such as a manually adjustable telescopic rod or an electrically adjustable telescopic rod.

[0030] Based on the above solution, in order to facilitate the adjustment of pressing block 2 and save on tool manufacturing costs, such as Figure 4 and Figure 5 As shown, the adjusting component includes:

[0031] Fixed block 4 is rotatably mounted on the shaping wheel 3 with the shaping wheel 3 as the axis;

[0032] Adjusting block 401 is rotatably disposed at the end of pressing block 2. Adjusting block 401 is provided with connecting block 403, which is slidably disposed on fixed block 4.

[0033] Fasteners are provided on connecting block 403 and are used to fix connecting block 403 to fixing block 4.

[0034] Specifically, when adjusting the position of the pressing block 2, the copper tube body 1 is used for auxiliary adjustment, rotating the pressing block 2 to the desired position. Figure 3 As shown, the copper tube body 1 is inserted between the pressing block 2 and the shaping wheel 3. If the diameter of the copper tube body 1 is large and it is interfered with by the arc groove of the pressing block 2 or the shaping wheel 3, the limiting of the connecting block 403 is released by the action of the fastener. At the same time, the position of the connecting block 403 in the fixing block 4 is adjusted, thereby changing the length of the connecting rod formed between the fixing block 4 and the adjusting block 401 until the copper tube body 1 can pass between the shaping wheel 3 and the pressing block 2. Finally, the connecting block 403 is limited again by the fastener. The length of the connecting rod formed between the fixing block 4 and the adjusting block 401 can be adjusted at will according to the different diameters of the copper tube body 1, so as to ensure that the adjusted pressing block 2 abuts against the copper tube body 1.

[0035] Specifically, in order to conveniently and quickly limit the connection block 403, the fastener is a fastening bolt 402. The fastening bolt 402 is threadedly connected to the connection block 403, and the end of the fastening bolt 402 passes through the connection block 403 and abuts against the inner side of the fixing block 4. When limiting or releasing the connection block 403, it is only necessary to tighten or loosen the fastening bolt 402, which makes the operation more convenient.

[0036] Based on the above solutions, such as Figure 2 and Figure 6 As shown, it also includes a fixing seat 6, which has an installation groove 601. A limiting seat 5 has an installation block 503, which is slidably disposed in the installation groove 601. When the installation block 503 slides within the installation groove 601, the position of the limiting seat 5 can be adjusted. When bending the copper tube body 1, the limiting seat 5 is needed to overcome the pressure applied by the copper tube body 1, thereby achieving the bending of the copper tube body 1. To ensure the bending accuracy of the copper tube body 1, when the copper tube body 1 is in such a position... Figure 3 When the position is shown, ensure that the copper tube body 1 and the limiting seat 5 are in contact to prevent the copper tube body 1 from moving upward when it is bent, which would cause the bending angle of the copper tube body 1 to not meet the expected setting, thus ensuring the processing accuracy.

[0037] Meanwhile, the side of the fixed seat 6 is threaded with a compression bolt 602, the end of which penetrates into the inner side of the mounting groove 601 and abuts against the mounting block 503. After adjusting the position of the mounting block 503 in the mounting groove 601, the mounting block 503 can be limited by tightening the compression bolt 602 to ensure the stability of the limiting seat 5.

[0038] Specifically, such as Figure 3As shown, a limiting wheel 502 is provided in the limiting groove 501, and the limiting wheel 502 rolls against the copper tube body 1; the limiting wheel 502 replaces the direct friction between the limiting groove 501 and the copper tube body 1, thus avoiding scratches on the copper tube body 1 to a certain extent.

[0039] Meanwhile, the limiting groove 501 extends through one side of the limiting seat 5 to form an open structure, allowing the copper tube body 1 to be directly placed inside through the limiting groove 501 of the open structure, facilitating rapid processing.

[0040] Specifically, such as Figure 2 As shown, both the fixed base 6 and the pressing block 2 are equipped with handles 7; this makes it convenient for the operator to operate manually and saves effort during operation.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
