Pipe bending machine used for bending oil pipes

Abstract

The invention discloses a pipe bending machine used for bending oil pipes. The pipe bending machine comprises stretch bending modules, jacking bending modules, twisting modules and a base (22). A pneumatic clamp is installed on the base (22), each stretch bending module comprises a stretching and retracting driving cylinder (1), a first reference rolling wheel (4) and a stretch bending rolling wheel (5), each oil pipe (6) is placed between the two corresponding rolling wheels, and piston rods of the stretching and retracting driving cylinders (1) retract to bend the oil pipes (6). The jacking bending modules comprise jacking driving cylinders (20), second reference rolling wheels (23) and jacking bending rolling wheels (24), each oil pipe (6) is placed between the two corresponding rolling wheels, and piston rods of the jacking driving cylinders (20) jack to bend the oil pipes (6). Each twisting module comprises a twisting driving cylinder (29) and a main shaft, a third reference rolling wheel (40) is arranged at the top of each main shaft, a rotating plate (41) is fixed to the main shaft, and a twisting rolling wheel (42) is arranged on the rotating plate (41). The pipe bending machine is high in speed, precision and efficiency.

Description

technical field [0001] The invention relates to a production equipment for auto parts, in particular to a pipe bending machine for bending oil pipes. Background technique [0002] The oil pipe of the car has multiple bends. The manufacturing process is to fix a straight oil pipe with a manual wrench clamp, and then the worker bends it with a manual wrench at the position where the straight oil pipe needs to be bent. Folding, that is, bending and forming by hand. The defects of manual operation are obvious, such as low efficiency, high labor intensity, and low precision, and it is difficult to control and unify the bending angle and strength. Because the automobile oil pipe has many bends, the angles and directions of the bends are different, and the height of the bends is not uniform, there is no mechanical equipment specially used for bending the oil pipe in the prior art. Contents of the invention [0003] The technical problem to be solved by the present invention is ...

AI Technical Summary

Problems solved by technology

The shortcomings of manual operation are obvious, such as low efficiency, high labor intensity, and low precision, and it is difficult to control and unify the bending angle and strength

Due to the many bends of automobile oil pipes, the bending angles and directions are different, and the height of the bends is not uniform, there is no mechanical equipment specially used for bending oil pipes in the prior art.
