Stainless steel pipe weld joint grinding and polishing device

Abstract

The invention discloses a stainless steel pipe weld joint grinding and polishing device. The grinding and polishing device comprises a device body, wherein a polishing channel and an attraction cavityare sequentially formed in the device body from top to bottom, an annular cylinder is connected to the inner wall of the polishing channel, a stainless steel pipe is arranged in the annular cylinderin a penetrating mode, and the annular cylinder is internally provided with polishing wheel adjusting mechanisms symmetrical with respect to the stainless steel pipe; one side of the annular cylinderis provided with a polishing driving mechanism, the polishing channel is connected with abutting blocks, the abutting blocks are connected with the polishing channel through springs, and air leading ports are formed in the inner wall of the polishing channel. The device has the advantages that the two polishing wheel adjusting mechanisms are arranged, so that two polishing wheels simultaneously polish a welding joint, then the polishing period is shortened, and the polishing efficiency is improved; particles are introduced into the attraction cavity through the characteristic of ferromagnetismof the particles in the polishing process to be attracted by a soft electromagnetic tape and then scraped by a scraping plate to be collected in a dust collection cavity, so that dust particles are effectively prevented from randomly dispersing, and the environment of a workshop and the bodies of workers are protected.

Description

technical field [0001] The invention relates to the technical field of polishing devices, in particular to a stainless steel pipe welding seam grinding and polishing device. Background technique [0002] Stainless steel pipe is a kind of hollow long round steel, which is mainly used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. [0003] When using stainless steel pipes, it is often necessary to weld two or more sections of stainless steel pipes to meet the construction requirements. The welds formed by welding need to be processed by a grinding and polishing device, which is convenient for construction and increases the beautification of the appearance. T...

AI Technical Summary

Problems solved by technology

The grinding and polishing device in the prior art has the following technical defects: 1. It can only polish stainless steel pipes of one diameter type. When polishing stainless steel pipes of different diameter types, it is necessary to replace the polishing wheel or the sleeve changing device, which is less applicable. Poor; 2. During the polishing process, there will be a lot of relatively fine particle impurities, which are not collected and treated, and let them float away, which will pollute the workshop environment and also affect the body of the processing personnel
