[0002] A seamless steel pipe is a kind of steel pipe without welding seam, which is made of a whole round steel through a perforation process, and the whole pipe wall is integrally formed without welding seam. In the production process of the seamless steel pipe, a steel pipe straightening machine is a key equipment for ensuring the size precision and appearance quality of the steel pipe, and its main function is to correct the bending or deformation of the steel pipe in the production process, so as to restore the steel pipe to a straight state. The existing straightening machine can be used for straightening operations of metal profiles, bars, pipes and wires, and mainly changes the straightness of the materials through extrusion of straightening rollers. There are two types of straightening rollers or two-roller straightening machines.

[0003] However, in actual application, when the steel pipe needs to be straightened, its surface is usually covered with rust, so it also needs to be rusted and polished in the straightening process. The steel pipe processing equipment generally has the problem of single function. For the steel pipe which needs to be straightened and rusted, two sets of equipment are often required for processing respectively, which leads to a substantial increase in equipment cost, a high overall cost of steel pipe processing, and low processing efficiency. In addition, the existing steel pipe rust removal and polishing device lacks a rust removal device, which cannot clean the rust in time. The rust may be clamped into the inside of the steel pipe, affecting the internal quality of the steel pipe. The accumulation of rust will also accelerate the corrosion process of the steel pipe and shorten the service life of the steel pipe.
