Tube bender for bending tubing

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 bender for bending oil pipes. Background technique [0002] The automobile's oil pipe has multiple bends. The manufacturing process is to clamp and fix a straight oil pipe by a manual wrench-type clamp, and then bend it with a manual wrench at the position where the straight oil pipe needs to be bent. Folding, that is, purely manual bending and forming. The shortcomings of manual operation are obvious, low efficiency, high labor intensity, and low precision, and the bending angle and strength are difficult to control and unify. Due to the many bends of automobile oil pipes, the different angles and directions of the bends, and the height of the bends are not uniform, there is no mechanical equipment specifically used for bending the oil pipes in the prior art. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a p...
