Protective cutting treatment machine for seamless metal pipe

Abstract

The invention relates to the field of non-ferrous metal treatment, in particular to a protective cutting treatment machine for a seamless metal pipe. The technical problem to be solved by the invention is to provide the protective cutting treatment machine for the seamless metal pipe. The protective cutting treatment machine for the seamless metal pipe comprises a first underframe, a second underframe and the like; and the second underframe is fixedly connected to the left side of the first underframe. According to the invention, a traditional metal pipe end face cutting device is abandoned; the cutting position of the metal pipe is marked and positioned firstly; the maximum material retention rate is guaranteed; meanwhile, the inner side wall face of metal is supported; it is guaranteed that the inner side of the metal pipe cannot be sunken when the metal pipe is cut; the integrity of end face cutting is improved; during cutting, filaments generated by cutting the end face are removed; redundant edges are polished; it is guaranteed that the surface of the end face of the metal pipe is qualified; and the stability of follow-up matched connection between pipes is improved.

Description

Technical field [0001] The present invention relates to a non-ferrous metal treatment field, and more particularly to a protective cutting processor of a seamless metal tube. Background technique [0002] Prior art in order to increase the anti-corrosion resistance of the metal tube, the manufacturing of the seamless metal pipe is usually used in the mold in-mold high temperature spraying, so that there is no welding between the outer surface of the metal tube and the inner surface, therefore It can improve the anti-corrosion resistance of the metal tube; [0003] However, there must be a connection between the tube and tube between the metal tube, so the integrity of the end surface of the metal tube is extremely important for the material delivery of the metal tube, and the prior art cutting of the seamless metal tube is still not protected. The cutting method is to cut the cutting blade directly, but the thickness of the seamless metal tube is small, and the deformation occurs...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the fact that the integrity of the end face of the metal pipe is extremely important for the material transportation of the metal pipe, the cutting of the seamless metal pipe in the prior art still stays in the unprotected cutting method, that is, the cutting blade is directly cut, but the seamless metal pipe The thickness of the tube is small, and it will be deformed during cutting. It is difficult to trace the deformation of the tube mouth back to the same specification as the tube body, and it is difficult to arrange the cutting filaments at the end face during cutting, so that the surface of the metal tube is still Need to carry out the second de-filament treatment, and its shortcoming that affects the production efficiency, the technical problem of the present invention is: provide a kind of protection cutting processing machine of seamless metal tube
