A grinding and derusting device for serpentine metal threading pipe before galvanizing

Abstract

The invention relates to a grinding and derusting device for a serpentine metal threading pipe before galvanizing. The rust removal treatment on the surface of the metal threading pipe is completed through the cooperation of a working plate, a fixing unit, a straightening unit and a derusting unit. The invention provides a grinding and derusting device for serpentine metal threading pipes before galvanizing, which can solve the problem of manually using sandpaper or an angle grinder to manually derust the outer surface of the serpentine metal threading pipes. Grinding and derusting the surface, because the length of the threading pipe is long, and it is difficult to polish and derust the folds of the threading pipe, resulting in low efficiency of manual derusting. In addition, the existing serpentine metal threading pipe galvanizing equipment generally First lock and fix the serpentine metal threading pipe, and then polish and derust the locked and fixed threading pipe. It is difficult to polish and derust the bend of the threading pipe, so that the rust removal on the outer surface of the threading pipe is not complete, which affects the threading The effect of galvanizing on the surface of the pipe and other issues.

Description

technical field [0001] The invention relates to the technical field of threading pipe production, in particular to a grinding and derusting device for serpentine metal threading pipes before galvanizing. Background technique [0002] The full name of the threading pipe is "insulating electrical bushing for construction". Generally speaking, it is a hollow pipe. The threading pipe is mainly used for anti-corrosion, anti-leakage, and pipes for threading wires; the threading pipe is mainly divided into plastic threading pipes and stainless steel threading pipes. Pipes and carbon steel threading pipes; threading pipes are mainly used in normal indoor environments and places with high temperature, dust, vibration and fire hazards; threading pipes must be used for wires buried in walls, and metal threading pipes and PVC threading pipes are generally optional There are two kinds of pipes. Metal threading pipe is more expensive, but its anti-interference performance is stronger than...

AI Technical Summary

Problems solved by technology

[0003] The existing serpentine metal threading pipe galvanizing equipment has the following problems when derusting the serpentine metal threading pipe before galvanizing: (1) when the outer surface of the serpentine metal threading pipe is derusted manually Usually, the outer surface of the serpentine metal threading pipe is polished and derusted directly by using sandpaper or an angle grinder, because the length of the serpentine metal threading pipe is long, and it is difficult to polish and remove the folds of the serpentine metal threading pipe (2) When the existing serpentine metal threading pipe galvanizing equipment derusts the serpentine metal threading pipe, it usually locks and fixes the serpentine metal threading pipe first, and then locks the The threading pipe after tightening is polished and derusted, and it is difficult to polish and derust the bending part of the threading pipe, so that the rust removal of the outer surface of the threading pipe is not complete, which in turn affects the effect of galvanizing on the surface of the threading pipe
