Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a metal pipe inner wall grinding device. Background Art

[0002] As the name implies, metal pipes are pipe fittings made of metal as raw materials. Metal pipe fittings have high strength, high flame retardancy, and high temperature resistance, and are widely used in steam pipes and hot water pipes. In the use of existing metal pipes, it is often necessary to butt multiple metal pipes together, and the inner walls of some metal pipes are not smooth enough, which easily leads to the connection between metal pipes not being tight enough and leaking. Therefore, in order to make the butt joint of metal pipes tighter and more airtight, the inner wall of the metal pipe needs to be polished during the processing of the metal pipe. However, most of the existing polishing equipment for the inner wall of metal pipes has a relatively single function, and a large amount of metal dust is easily generated during the polishing process. These metal dusts overflow into the air, which will cause certain pollution to the environment. At the same time, these metal dusts are inhaled by the operator, which will cause great harm to the operator's body. In addition, a large amount of metal debris generated during the polishing process remains on the workbench, which is difficult to clean and increases the workload. Summary of the invention
