Because the shot flies out from the upper side and the lower side of the steel pipe, the upper side and the lower side of the steel pipe are hit by a large amount of shot, the surface treatment is relatively easy to finish, but the horizontal two sides of the steel pipe are only hit by a small amount of shot, longer treatment time is needed, the time required for the steel pipe to pass through a shot blasting machine is longer, the steel pipe cannot pass through quickly, and when the steel pipe is used for treating the steel pipe with larger general structural strength, the problem of production efficiency reduction is avoided, but when the steel pipe is used for a precise pipe with smaller structural strength, the steel pipe is deformed due to long-time stress. In the existing shot blasting machine, the shot blasting machine is used for ensuring that the shot blasting material has a larger speed in the advancing direction of the steel pipe in which the rotating plane is parallel, the shot blasting machine also has a larger rotating diameter, the length of a shell is difficult to be well compressed, the suspension distance of the precise pipe in the shot blasting machine is large, and the precise pipe is further deformed easily.

Therefore, the existing shot blasting machine has the defects of lower production efficiency and easy deformation of the precision tube when being used for the surface treatment of the precision tube.
