Anti-deformation polishing machining device based on thin-walled steel pipe

Abstract

The invention discloses an anti-deformation polishing machining device based on a thin-walled steel pipe. The anti-deformation polishing machining device comprises a base and a machine body, the machine body is fixedly arranged on the top surface of the base, a supporting platform is fixedly arranged on the top surface of the base, the thin-walled steel pipe can be placed on the top surface of thesupporting platform, the supporting platform is located on the left side of the machine body, a lifting cavity with a leftward opening is formed in the machine body, and a moving cavity with a leftward opening is formed in the lower side of the lifting cavity in a communicating mode. According to the anti-deformation polishing machining device, a method of manual positioning is adopted to make amachining part in the device always at the same level with the steel pipe, the machining applicability of the steel pipes with different diameters is effectively improved, a method of rotating an arc-shaped supporting plate outward to expand and cling to the inner wall of the steel pipe is adopted, and the deformation of the thin-walled steel pipe caused by the excessive polishing pressure when the thin-walled steel pipe is polished on the outer side can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to an anti-deformation polishing processing device based on thin-walled steel pipes. Background technique [0002] Steel pipes, as a pipeline product, are widely used in water bodies or gas transportation devices. Generally, when steel pipes are installed, multiple steel pipes need to be fixedly connected together to form a conveying channel. Generally, welding is used for fixed connection, but , if the outer surface of the steel pipe is very rough and not smooth, it is easy to cause cracking or collapse after connection. Therefore, the outer surface of the steel pipe must be polished before connection; [0003] With the continuous development of science and technology, the wall thickness of the steel pipe can be made very thin, but this brings certain difficulties to polishing. Due to the thin wall thickness, it is very easy to cause deformation of the thin-walled ste...

[0002] Steel pipes, as a pipeline product, are widely used in water bodies or gas transportation devices. Generally, when steel pipes are installed, multiple steel pipes need to be fixedly connected together to form a conveying channel. Generally, welding is used for fixed connection, but , if the outer surface of the steel pipe is very rough and not smooth, it is easy to cause cracking or collapse after connection. Therefore, the outer surface of the steel pipe must be polished before connection;

[0003] With the continuous development of science and technology, the wall thickness of the steel pipe can be made very thin, but this brings certain difficulties to polishing. Due to the thin wall thickness, it is very easy to cause deformation of the thin-walled steel pipe during the polishing process, thereby affecting To the subsequent connection and fixation, generally in actual operation, the workers will add a support on the inner wall of the steel pipe and then polish it. This method is very troublesome, and it is difficult to ensure stability and reliability, and problems are prone to occur
