Description

Technical Field

[0001] The utility model belongs to the technical field of pipe bending machines, in particular to a serpentine pipe bending machine. Background Art

[0002] A pipe bending machine is generally composed of an electric oil pump, a high-pressure oil pipe, a quick connector, a working oil cylinder, a plunger, and pipe bending components. The high-pressure oil output by the electric oil pump is sent into the working oil cylinder through the high-pressure oil pipe. The high-pressure oil pushes the plunger in the working oil cylinder to generate thrust, and the pipe is bent through the pipe bending components. Hydraulic pipe bending machines are suitable for installing and repairing pipelines in factories, warehouses, docks, buildings, railways, automobiles, etc. Compared with CNC pipe bending equipment, they are cheap and easy to use, and they occupy a leading product position in the domestic pipe bending machine market.

[0003] According to a disclosed serpentine tube (publication number: CN2231753Y), it includes a clip, and a fixed layer is arranged on the periphery of the clip, and the fixed layer is connected to the serpentine tube. The utility model integrates the clip and the serpentine tube into one, and when using the serpentine tube, it is not necessary to equip the clip separately, which is more convenient. Moreover, since it is equipped with a fixed layer and connected to the serpentine tube, the clip can be fixed on the serpentine tube more stably and will not shift. When using, the fixed layer can be torn off, which can improve the installation speed. It is suitable for other plastic and rubber connecting tubes that need to be fastened with clips. However, in the above device, it is difficult to achieve the precise control and bending effect of the steel pipe through the mutual cooperation of the components such as the clip, the serpentine tube and the fixed layer, and it is difficult to ensure the accuracy and consistency of the bent pipe, which increases the demand for manual labor and reduces the production efficiency, and needs to be improved.
