Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending processing, and more specifically, to a bending device which is convenient for controlling the pipe bending processing angle. Background Art

[0002] A pipe elbow is a pipe fitting that changes the direction of a pipe. It is mainly used at pipe intersections, turns, and around beams. It is widely used in construction, automobile manufacturing and other fields.

[0003] The traditional bending device that is easy to control the bending angle of the pipe has the following shortcomings: the traditional bending device that is easy to control the bending angle of the pipe usually uses a round roller and a push rod to bend the bent pipe along the direction of the round roller, but due to the lack of a limit assembly on the round roller, the staff usually installs limit discs on the upper and lower ends of the round roller to limit the bent pipe. Since the sizes of different bent pipes are inconsistent and the bent pipes are generally cylindrical, when bending a bent pipe with a smaller diameter, the limit plate cannot effectively limit the bent pipe. Therefore, the pressure generated during the bending process may cause the bent pipe to deviate up and down, thereby affecting the bending efficiency. Therefore, it needs to be improved.
