Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a device for removing rust from the outer wall of a steel pipe by shot blasting. Background Art

[0002] Steel pipes have hollow cross-sections, and their length is much greater than the diameter or circumference of the steel. According to the cross-sectional shape, they are divided into round, square, rectangular and special-shaped steel pipes; according to the material, they are divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the purpose, they are divided into steel pipes for pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) types, and welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes. In the process of steel pipe processing, it is often necessary to use a shot blasting device to remove rust from the outside of the steel pipe. CN218613505U discloses a shot blasting device for the outer wall of a steel pipe. The rust removal device, by setting a spacing adjustment mechanism to push the two limit blocks close to the two sides of the steel pipe, can limit the transportation of the steel pipe and prevent the steel pipe from deflecting, and can limit and guide steel pipes of different diameters and specifications, thereby improving the processing application range. The conveying mechanism is set to realize automatic conveying of the steel pipe, and the conveying is stable so as to perform shot blasting and rust removal processing. However, the shot blasting and rust removal device is easy to lift up the steel pipe when limiting and fixing the steel pipe with a larger diameter, which will cause the bottom of the steel pipe to not contact the top of the conveying roller, and then cause the steel pipe to be unable to be transported, which greatly reduces the effect of shot blasting and rust removal of the steel pipe, and brings certain adverse effects on actual use, so it needs to be improved.
