Application method of tool applied to inner wall cleaning of tube fittings

Abstract

The invention discloses the application method of the cutter used for cleaning the inner wall of pipe fittings. When the central axis rotates the arc-shaped blade and contacts the solder residue and protrusions on the inner wall of the steel pipe, the interaction force on the arc-shaped blade produces a relatively large impact on itself , the stopper can provide support for the arc-shaped blade when the angle between the arc-shaped blade and the central axis reaches the maximum and also when the arc-shaped large piece is impacted the most, so as to avoid damage to the arc-shaped blade.

Description

technical field [0001] The invention relates to auxiliary equipment for an argon arc welding machine, in particular to an application method of a cutter used for cleaning the inner wall of a pipe fitting. Background technique [0002] When welding steel pipes, in order to ensure a good welding effect, the welding head and the steel pipe to be welded are generally placed in a semi-closed box to facilitate the introduction of protective gas and avoid sparks splashing around during welding. However, after the partial welding of the steel pipe is completed, the weld seam is directly exposed to the air. Due to the difference between the air temperature and the temperature of the weld seam itself, the weld seam will directly change from high temperature to low temperature. The strength of the steel itself reduces the stability of the steel pipe, and in severe cases it will directly cause the weld seam of the steel pipe to be de-welded; and a certain amount of burrs will be generat...

Problems solved by technology

However, after the partial welding of the steel pipe is completed, the weld seam is directly exposed to the air. Due to the difference between the air temperature and the temperature of the weld seam itself, the weld seam will directly change from high temperature to low temperature. The strength of the steel itself reduces the stability of the steel pipe, and in severe cases it will directly cause the weld seam of the steel pipe to be de-welded; and a certain amount of burrs will be generated inside and outside the steel pipe near the weld seam during welding, which makes the flow rate of the fluid in the pipe drop when the steel pipe is in use. , and the protrusions at the weld are easily corroded, which leads to a decrease in the overall strength of the weld and reduces the service life of the steel pipe; traditional internal burr removal equipment mainly focuses on the solder residue and protrusions around the weld and the weld However, the solder residue and protrusions scattered to other parts of the inner wall of the steel pipe during welding are not cleaned thoroughly
