Inner wall polishing rust-proof device for steel pipes

Abstract

The invention discloses an inner wall polishing rust-proof device for steel pipes, and relates to the technical field of steel pipe machining polishing. The inner wall polishing rust-proof device comprises a base table, a conveying mechanism is fixedly installed on the left side of the upper surface of the base table, and a material pushing mechanism is fixedly installed on the middle portion of the upper surface of the base table. A linkage mechanism, a polishing mechanism, a cleaning mechanism and a paint spraying mechanism are fixedly installed on the right side of the upper surface of the base table. According to the inner wall polishing rust-proof device for the steel pipes, the short steel pipes are horizontally placed in a discharging frame, the short steel pipe at the bottom end falls into a top groove of a bearing base, the telescopic end of a first electric push rod stretches out to push a push column to move towards the left side, and the polishing mechanism, a cleaning mechanism and a paint spraying mechanism are driven to synchronously move through stretch-out and draw-back of the first electric push rod. When the steel pipe on the bearing base is pushed to be fed to the left side, the steel pipe which rotates by a circle and is polished, cleaned and subjected to paint spraying is ejected to the left side, the short steel pipe is guided out through guiding of a discharging groove, and the effect of synchronous polishing, cleaning, paint spraying and material returning is achieved in the conveying process.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing and grinding, in particular to an inner wall grinding and rust prevention device for steel pipes. Background technique [0002] Steel pipe is a hollow rod-shaped structure. In practical applications, short steel pipes need to connect multiple steel pipes together, or assemble short steel pipes with other structures. Short steel pipes are widely used in people's daily life, whether in houses Short steel pipes can be seen in buildings or on automobiles and ships. After the completion of the manufacture or maintenance of the used steel pipes, it is often necessary to polish the inner wall to avoid rust and corrosion from the inside during use and affect the quality of the steel pipes. service life. [0003] When the steel pipe grinding device is in use, gauze is usually used to polish the outside. When it is internally treated, a grinding rod or sandpaper is usually inserted into the i...

Problems solved by technology

[0003] When the steel pipe grinding device is in use, gauze is usually used to polish the outside. When it is internally treated, a grinding rod or sandpaper is usually inserted into the inside of the steel pipe with a stick for friction and grinding back and forth. However, in the process of production or maintenance , the efficiency of grinding its inner wall is low, and it is difficult to clean and paint the inside after grinding
