[0002] The automobile exhaust system is located at the bottom of the vehicle, connecting the engine exhaust end with the atmosphere. Its main function is to discharge the exhaust gas generated by the engine, purify the exhaust gas, and reduce noise. The exhaust tail pipe is located at the tail end of the engine exhaust pipe, which plays the role of exhaust gas and decoration. The exhaust pipe involves arc-shaped pipe bending in production. The pipe bending is formed by bending thin-walled steel pipes. After bending and forming by a bending machine, in order to fit the chassis of the car, the middle part of the exhaust pipe needs to be flattened to make it fit the chassis of the car better.

The utility model provides a pipe bending device for automobile exhaust pipes, which has a reasonable structure, good pipe bending effect, and will not cause the problem of excessive extrusion and deformation, thereby improving the quality of exhaust pipe forming.

The bending roller and the bending fixing plate are connected by a connecting rod, so it is inconvenient to feed the material and it is not convenient to bend pipes of various diameters. Therefore, there is room for improvement. Utility Model Content
