Polishing rust-proof device for steel structure machining

Abstract

The invention discloses a polishing rust-proof device for steel structure machining, and relates to the technical field of steel structure machining. The problem that a steel structure cannot be effectively polished thoroughly is solved. The device specifically comprises a base and a supporting table which is fixed to the top end of the base, plays a supporting role and inclines upwards, a pretreatment frame is fixed to one side of the top end of the base through screws, a through hole of an H-shaped structure is formed in the side wall of the pretreatment frame, and two or more sets of ballsare rotationally connected to the top end and the bottom end of the through hole; and a fixing frame of a portal frame structure is arranged on the side wall of the base, and a frosted frame with theinner layer of a frosted structure is arranged at the bottom end of the fixing frame. The pretreatment frame provided with the balls is arranged, and the balls can roll under friction of the H-shapedsteel structure to give certain vibration to the H-shaped steel structure, so that large-particle rust chips attached to a surface layer of the H-shaped steel structure can be shaken to reduce the pressure of subsequent frosted chip removal, and the phenomenon that the rust chips hidden below the H-shaped steel structure and fastened are not completely polished is avoided.

Description

technical field [0001] The invention relates to the technical field of steel structure processing, in particular to a grinding and antirust device for steel structure processing. Background technique [0002] In the production and processing of steel structures, due to the inevitable burrs or uneven surface of the workpiece, or when cleaning the rust and stains on the surface, it needs to be polished. The current steel grinding is often done manually with a hand-held grinder or with a grinding device. [0003] After searching, the Chinese patent application number is 201920070052.4, which discloses a grinding device for steel structure processing, including a workbench and a support frame; the support frame is fixed on the upper part of the workbench; the bottom surface of the support frame is set There is a grinding assembly; the grinding assembly includes a first slide rail, a second slide rail, a motor and a polishing sheet; the first slide rail is fixedly connected to t...

AI Technical Summary

Problems solved by technology

A grinding device for steel structure processing in the above-mentioned patent has the following disadvantages: when the steel structure is polished and derusted, although the device can use a motor to drive the polishing sheet to polish the surface of the steel structure, the diameter of the polishing sheet is limited. When grinding the H-shaped steel structure, because of its unique shape and structure and the surface rust generally has some loose rust particles, a single polishing piece can only rotate and polish the steel structure part, which leads to the steel structure prone to appear in the process of grinding and derusting the steel structure. There are many and uneven scratches on the surface, and the rust under the loose rust cannot be effectively polished.
