Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a circular pipe fitting incision grinding device. Background Art

[0002] Round tube refers to steel with two ends open and a hollow concentric cross section, with a large ratio of length to circumference, which can be used for pipelines, thermal equipment, mechanical industry, petroleum geological drilling, containers, chemical industry and special purposes;

[0003] In the process of production and processing of existing circular pipe fittings, the pipe fittings need to be cut and the cut edges need to be polished to avoid burrs on the ends of the pipe fittings that affect the subsequent use of the pipe fittings. At present, a corresponding polishing device is required when polishing the key cut edges. In actual use, the existing pipe fitting cut edge polishing devices mostly use motors to drive the polishing plates to directly fit the cut edges. However, the inner and outer peripheries of the pipe cut edges are not polished thoroughly, so there are still burrs that affect subsequent use. Therefore, we propose a circular pipe fitting cut edge polishing device. Utility Model Content

[0010] By adopting the above technical solution, the turntable is limited by the limit slider during its rotation, thereby ensuring the stability of the turntable's rotation.
