Steel tube inner wall polishing machine

Abstract

The invention relates to a steel tube inner wall polishing machine. The steel tube inner wall polishing machine comprises fixing mechanisms and polishing mechanisms and further comprises a feeding area and a transverse movement rail. The polishing mechanisms comprise the first polishing mechanism and the second polishing mechanism, and the first polishing mechanism and the second polishing mechanism are arranged on the two sides of the feeding area correspondingly. The fixing mechanisms comprise the first fixing mechanism and the second fixing mechanism, and the first fixing mechanism and thesecond fixing mechanism are arranged on the transverse movement rail in a slippage manner correspondingly. The transverse movement rail is provided with a first drive device. By the adoption of the scheme, the two fixing mechanisms and the two polishing mechanisms are arranged, when a tube on one of the fixing mechanisms is subjected to polishing, the other fixing mechanism can detach a polished tube and install a tube to be polished, the tube needing to be polished can be subjected to polishing directly after polishing is finished, therefore the preparation time between two times of polishingis eliminated, and the steel tube inner wall polishing machine has high work efficiency.

Description

technical field [0001] The invention relates to the technical field of polishing machines, in particular to a steel pipe inner wall polishing machine. Background technique [0002] Steel pipes are widely used in the field of pipelines due to their stable chemical properties, cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance. In the manufacturing process of the steel pipe, due to the existence of manufacturing processes such as hot rolling and cold rolling, unevenly distributed burrs are inevitably formed on the inner surface of the steel pipe, resulting in poor flatness of the inner surface of the steel pipe. Therefore, it is necessary to deal with the burrs on the surface of the steel pipe. Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is a modification process on the surface of the workpiece by using poli...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned steel pipe inner wall polishing machine can only polish one steel pipe at a time, that is, when the steel pipe is installed to the fixing mechanism, the polishing mechanism is in an idle state, and when the polishing mechanism is in a working state, it cannot prepare for the next polishing. As a result, there is a time difference between two polishings, resulting in lower production efficiency
