Description

Technical Field

[0001] The utility model belongs to the field of steel pipe grinding, and particularly relates to a grinding device for steel pipe welding. Background Art

[0002] A steel pipe is a pipe with a hollow cross-section made of steel. Steel pipes are not only used for transporting fluids and powdered solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economical type of steel. Using steel pipes to manufacture building structure grids, supports, and mechanical brackets can reduce weight and enable factory-based and mechanized construction. When using steel pipes, to meet the usage requirements, several steel pipes generally need to be welded together to reach the predetermined length.

[0003] When steel pipes are welded, protrusions will be generated at the welding joints, which will not only increase the diameter of the steel pipes but also affect their appearance. Therefore, it is necessary to grind the welded parts of the steel pipes. Generally, manual grinding is used for the welded parts of the steel pipes. When grinding manually, the steel pipes need to be fixed first, and then the grinding paper or angle grinder is held manually to grind the welded parts of the steel pipes. This not only requires a lot of physical strength but also takes a long time for grinding, resulting in low work efficiency.

[0004] To avoid the above technical problems, it is indeed necessary to provide a grinding device for steel pipe welding to overcome the defects in the prior art. Content of the Utility Model
