Description

Technical Field

[0001] The utility model belongs to the technical field of welded pipe processing equipment, in particular to a grinding device for welded pipe processing. Background Art

[0002] With the development of science and technology, welding technology has gradually matured. In terms of welded steel pipes, it refers to steel pipes with seams on the surface that are made by bending steel strips or steel plates into round, square and other shapes and then welding them. However, the surface of the welded pipe needs to be polished during the processing to avoid the surface of the welded pipe being too rough and affecting the appearance. Therefore, a grinding device for welded pipe processing is needed.

[0003] A Chinese patent application with publication number CN220446006U discloses a grinding device for welding pipe processing, including a grinding device body, a mounting frame fixedly connected to the upper surface of the grinding device body, two air purifiers fixedly connected to the upper surface of the mounting frame, a telescopic cylinder fixedly connected to the inner wall of the grinding device body, and a grinding motor fixedly connected to the output end of the telescopic cylinder. This device can start the driving motor to drive the bidirectional threaded rod to rotate through the set operation touch panel, so that the bidirectional threaded rod cooperates with the slider, the limit block and the slide groove to realize the sliding of the clamping arm inside the limit groove and contact and fix with the welding pipe. Through the cooperation of the above structures, this device can realize automatic operation, reduce the tedious operation of manual fixation of the welding pipe, and drive to improve work efficiency. At the same time, the automatic fixation can ensure the accurate position of the welding pipe and avoid the deviation or shaking of the welding pipe during the grinding process. It is very practical and stable.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the above-mentioned grinding device for processing welded pipes, the grinder can only grind the uppermost part of the welded pipe, which results in the need for multiple installations for comprehensive grinding of the welded pipe, thereby reducing the work efficiency;
