Problems solved by technology
At present, the bending method of the oil pipe mostly adopts the bending machine or the bending tool. The bending machine has high working efficiency and the product consistency can be guaranteed. However, the bending machine can only bend the straight oil pipe. Formed tubing cannot be adjusted
In addition, the bending tool takes up a lot of space, is not easy to carry, and is inconvenient to use on the assembly site. When the oil pipe assembly station needs to adjust the angle of the oil pipe, manual correction is often used. Manual correction is laborious and cannot ensure the consistency of the oil pipe angle.

Embodiment Construction
[0015] see Figure 1-3 , the present invention is a hand tool composed of two stacked handles, one side of which is hinged by a pin shaft 2, and the two handles can rotate relative to each other. Wherein, the hinge side end of the first handle 1 at the upper part is provided with an oil pipe stopper 3, and the space between the oil pipe stopper and the protruding pin shaft head forms the oil pipe limit groove 10; the second handle 5 at the lower part A tubing bending shaft 4 is arranged adjacent to the pin shaft.
[0016] see Figure 4 , in order to reduce frictional resistance and prevent oil pipe surface damage during the bending process, a nylon roller sleeve 9 is set on the oil pipe bending shaft 4, the nylon roller sleeve and the oil pipe bending shaft have a clearance fit, and the nylon roller sleeve is provided with an annular oil pipe Groove 9-1, the position of the oil pipe groove corresponds to the position of the pin shaft head.

The invention discloses an automobile oil pipe bending straightening tool for solving the oil pipe bending and straightening problems of an assembly field. The invention adopts the technical scheme that: the tool consists of two superposed handles hinged by a pin shaft on one respective side, wherein the hinged end of the first handle positioned on the upper part is provided with an oil pipe baffle table, an oil pipe limiting groove is formed between the oil pipe baffle table and the head of the pin shaft, and an oil pipe bending shaft is arranged on the second handle positioned on the lower part close to the pin shaft. The bending angle of an oil pipe can be freely adjusted according to the assembly requirement, the angle consistency of the processed oil pipe can be ensured, and the straightening problem of oil pipe assembly is solved with low investment cost. The tool has simple structure, and is novel in design, low in manufacturing cost, convenient to carry around and convenient to use.
Description
technical field [0001] The invention relates to a hand tool, in particular to a special tool for bending or correcting the angle of an automobile oil pipe, and belongs to the technical field of automobiles. Background technique [0002] The automobile pipeline is an important part of the automobile. During the automobile assembly process, the oil pipe needs to be processed into different angles according to different vehicle models and different layout structures, so as to meet the requirements and position layout of the used parts. At present, the bending method of the oil pipe mostly adopts the bending machine or the bending tool. The bending machine has high working efficiency and the product consistency can be guaranteed. However, the bending machine can only bend the straight oil pipe. Formed tubing cannot be adjusted. In addition, the bending tool takes up a lot of space, is not easy to carry, and is inconvenient to use on the assembly site. When the oil pipe assembly...
