Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, and specifically relates to a bending device for pipe fitting processing. Background Technique

[0002] During the production and manufacturing of pipelines, according to the usage scenarios, the pipelines will be bent at a certain angle to change the positions of the pipeline inlets and outlets.

[0003] A Chinese patent discloses a bending device for processing pipe fittings of a carport bracket, with the publication number CN214263384U, which includes a box body. A rotating disk is rotatably installed on the top of the box body. Positioning columns are fixedly installed on the top of the rotating disk. A bending column is fixedly installed on the top of the rotating disk, and the bending column is adapted to the corresponding positioning column. A pipe fitting is arranged on the top of the box body, and the pipe fitting is adapted to the positioning column and the bending column. A fixed seat is fixedly installed on the top of the box body. A positioning groove is opened on one side of the fixed seat, and the pipe fitting is adapted to the corresponding positioning groove. Two symmetrically arranged first grooves are opened on one side of the fixed seat. A moving plate is slidably installed in the first groove, and arc-shaped clamping plates are fixedly installed on the sides of the two moving plates close to each other, and the arc-shaped clamping plates are adapted to the corresponding pipe fittings. The utility model has reasonable design, simple structure and convenient operation, and is convenient for fixing the pipe fittings, so as to facilitate bending the pipe fittings.

[0004] However, it still has the following disadvantages: The device drives the rotating disk to rotate, so that the bending column bends the pipeline, but the device cannot adjust the angle of the pipeline and cannot perform multi-angle folding in space as required, resulting in low practicability of the device. For this reason, we propose a bending device for pipe fitting processing to solve this problem. Content of the Utility Model
