Steel pipe surface multi-stage grinding treatment machine

Abstract

The invention relates to a steel pipe surface multi-stage grinding treatment machine. The steel pipe surface multi-stage grinding treatment machine comprises a mounting base, a fixed base, a limitingplate, grinding devices, inner support devices and a screw, the limiting plate is mounted between the upper end of the mounting base and the upper end of the fixed base, the grinding devices are evenly distributed between the limiting plate and the screw, the inner support devices are mounted on the centers of the grinding devices, and are mounted on the mounting base, the screw is mounted betweenthe mounting base and the fixed base through a bearing, the screw is located on the right below end of the limiting plate, and the problems that after an existing traditional grinding machine grindsa steel pipe, the surface is still not smooth, dust scrap materials remaining on the steel pipe surface can cause scratches and hollow points in the grinding process of the steel pipe, in the grindingprocess, the dust scrap materials floating in the air can appear, after being aspirated by a worker, the materials can cause body discomfort, and heat generated in the grinding process can damage thegrinding devices are solved.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a processing machine for multi-stage grinding of steel pipe surfaces. Background technique [0002] A steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. Steel pipes are not only used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers, but they are also economical steel pipes. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight and realize factory-like mechanized construction. Under various working conditions, there is a certain demand for the smoothness of the steel pipe surface. However, the smoothness of the steel pipe surface is usually not high, which will affect the use of the steel pipe. [0003] At present, there are usually the following defects in the surface treatment of steel pipe...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that the existing traditional grinding machine cannot perform multi-stage grinding on the steel pipe, resulting in that the surface of the steel pipe is still not smooth enough after grinding, and the dust and debris remaining on the surface of the steel pipe will cause scratches and
