Copper removal brush for gun barrel

Abstract

A copper removal brush for a gun barrel is formed by a brush head, a pipe brush and a brush handle which are connected into a whole; an air inlet plug and one end of a screw plug are connected with two ends of the brush handle respectively; the screw plug is provided with a liquid shifting hole and a liquid leakage hole which are communicated with each other; the brush head and the other end of the screw plug are connected with two ends of the pipe brush respectively; a screw plug end of the pipe brush is connected with a liquid coating plate which is closely attached to the liquid leakage hole formed in the screw plug. The diameter of the liquid shifting hole formed at the edge of the screw plug is small, the copper removal brush rotates to enable a solvent to be squeezed to the pipe wall under the action of the centrifugal force, easily enter the screw plug from the liquid shifting hole and flow onto wool felt through the needle point size of liquid leakage hole formed in the screw plug to be used, the liquid quantity is not large, and accordingly the flowing of liquid droplets is avoided, the use of a cleaning solution is reduced, and the pollution to the environment is not produced. The brush head is smooth and accordingly collisions and bruises of the inner wall of a gun bore are not produced, metal combustion materials and dirt of every position of the gun bore are removed through the spiral pipe brush, the sealing effect is achieved due to a sealing ring and the wool felt which are arranged at the brush handle end, and a copper removal agent can be uniformly brushed at every position of the inner wall of the gun bore without leakage due to the wool felt and accordingly the inner wall of the gun bore is fully utilized and is not damaged.

Description

technical field [0001] The invention relates to a cleaning and maintenance brush, in particular to a gun barrel copper-removing brush suitable for removing metal and gunpowder combustion residues on the inner wall of a pipe and a gun bore after a shell is fired. Background technique [0002] The gun barrel weapon must be cleaned and maintained after unsealing, firing and storage. After the gun barrel is fired, it needs to be descaled and cleaned, because the metal particles and gunpowder left when the shell passes through the gun barrel at high speed and burns Residues, soot and other residues will adhere to the inner wall of the gun bore. These residues will accumulate thicker and thicker with the increase in the number of shootings, causing deformation and corrosion of the inner wall of the gun barrel, which will affect the accuracy, reliability and service life of the shell. . Different use procedures of the gun barrel require different cleaning processes, and cleaning b...

Problems solved by technology

[0002] The gun barrel weapon must be cleaned and maintained after unsealing, firing and storage. After the gun barrel is fired and used, it needs to be descaled and cleaned, because the metal particles and gunpowder left when the shell passes through the gun barrel at high speed and burns Residues, soot and other residues will adhere to the inner wall of the gun bore, and these residues will accumulate and thicken as the number of shootings increases, causing deformation and corrosion of the inner wall of the gun barrel and affecting the accuracy, reliability and service life of the shell.

Different use procedures of the barrel require different cleaning procedures, and cleaning brushes with different functional structures are also required to complete the execution. However, the existing cleaning brushes still use the traditional structure and cannot meet the needs of cleaning and maintenance work.

[0003] Chinese Patent No. 03257016.3 "A Cannon Brush" and 03240386.0 "A Pipe Brush" provide a cleaning brush for cleaning and antirust oiling of various pipelines. The cleaning and oiling effects are poor and the work efficiency is low. Low, unable to meet the needs of existing cleaning and maintenance work
