Large-inside-diameter steel pipe inner wall derusting device for machining

Abstract

A device for removing rust on the inner wall of a steel pipe with a large inner diameter for mechanical processing, including a base plate, on which a first shaft bracket is vertically and fixedly installed, and the first shaft bracket is movably connected to the right end of the drive shaft; the coaxial line on the drive shaft is fixedly installed with The first bevel gear, the upper end of the driven shaft is coaxially fixed with the second bevel gear, the second bevel gear is meshed with the first bevel gear, the lower end of the driven shaft is coaxially fixed with a runner, and the bottom plate is vertically fixed The second shaft bracket is installed, and the first connecting rod is horizontally slidable on the second shaft bracket; the limit roller is fixedly installed on the coaxial line on the rotating shaft, and the steel pipe for derusting is placed on the limit roller; on the first connecting rod The derusting roller is fixedly installed, and the surface of the derusting roller is uniformly provided with a wire brush, and a guide wheel is fixedly installed on the rotating roller, and the guide wheel is in contact with the outer surface of the derusting roller; The circumferential derusting effect makes the derusting effect of the inner wall of the steel pipe better.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a rust removal device for the inner wall of a steel pipe with a large inner diameter used for mechanical processing. Background technique [0002] Steel pipes are used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. It is also a kind of economical steel. The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry and Drilling, production and transportation of oil and natural gas have strongly promoted the development of steel pipe industry in terms of variety, output and quality. Steel pipes can be divided into two categori...

Problems solved by technology

[0003] Due to the limitation of steel pipe storage conditions, steel pipes will be corroded by oxides. Generally, steel pipe corrosion is chemical corrosion, and the speed is slow. After corrosion, a thin layer of porous brown rust is formed on the surface. It will slowly form perforation, so the steel pipe needs to be derusted before use to prevent the corrosion of the steel pipe from intensifying; and for the thick-walled steel pipe with a larger inner diameter, due to the larger inner surface area, the workload of rust removal is larger. The existing manual rust removal methods cannot meet the actual rust removal needs, and there is an urgent need for a large inner diameter steel pipe inner wall rust removal device for mechanical processing to improve the rust removal effect on the inner wall of large inner diameter steel pipes
