Equipment capable of removing rust on inner and outer surfaces of steel pipe

Abstract

The invention relates to equipment capable of removing rust on the inner and outer surfaces of a steel pipe. The equipment comprises a bracket, wherein a feeding assembly, a first rust removing assembly and a second rust removing assembly are sequentially arranged in the vertical direction of the bracket from bottom to top; the first rust removing assembly comprises a first cross beam, a first sliding rail and a first sliding seat; the first sliding seat is driven by a first air cylinder; a first supporting plate I is fixedly connected onto the first sliding seat; a first rust removing unit isarranged on the first supporting plate I; a second rust removing assembly comprises a positioning assembly and a second rust removing unit; the positioning assembly and the second rust removing unitare parallelly arranged on the bracket; the feeding assembly comprises a second cross beam, a third sliding rail and a third sliding seat; a fourth air cylinder and a plurality of guiding rods are arranged on the third sliding seat; a first supporting plate II is arranged on the guiding rods; a plurality of supporting columns are arranged on the first supporting plate II; a second supporting plateis fixedly connected with the outer ends of the supporting columns; a supporting block is fixedly connected onto the second supporting plate; the positioning assembly comprises a fixing unit and a moving unit; the fixing unit is fixedly connected onto the bracket; and the moving unit is capable of sliding on the bracket. The equipment provided by the invention has the automatic feeding function,the area occupied by the equipment is small, and the rust removing efficiency is high.

Description

technical field [0001] The invention belongs to the field of derusting steel pipes, in particular to a device capable of derusting the inner and outer surfaces of steel pipes. Background technique [0002] Steel pipe is an economical cross-section type of steel with a wide range of sizes, whether it is a capillary tube with a small diameter or a large diameter steel pipe with a diameter of several meters. It is characterized by not only openings at both ends but also a closed hollow section, and the ratio of its length to the perimeter of the cross-section is usually relatively large. Seamless steel pipes not only have round but also square, rectangular and other special-shaped cross-sections. Steel pipes are not only widely used in aerospace, shipbuilding, coal mine construction, boiler manufacturing, petroleum energy, construction and military industry, but also in home appliance manufacturing, bicycles, agricultural machinery and tools, etc. Its application plays an impo...

Problems solved by technology

[0004] Existing steel pipe derusting machines usually use a semi-automatic processing method for derusting, that is, manual feeding and mechanical derusting jointly remove the rust on the inner and outer walls of the steel pipe, and now the inner and outer walls of the steel pipe are usually derusted using two Different kinds of equipment, the equipment occupies a large area, which is not convenient for mass production
