Arc spray gun with protection structure

Abstract

The invention discloses an electric arc spray gun with a protection structure, which comprises an electric arc spray gun main body, one end of the electric arc spray gun main body is fixedly connected with an electric arc nozzle, two sides of the electric arc nozzle are fixedly provided with conductive nozzles, two sides in the two conductive nozzles are fixedly provided with hot melting blocks, and the center of the electric arc nozzle is fixedly provided with an air pipe. An elastic sealing piece is connected to the end of the air pipe, a corrugated pipe is installed on the side of the inner wall of the arc nozzle, a connecting pipe is fixedly connected to one end of the corrugated pipe, one end of the connecting pipe extends into the air pipe, and fixing blocks are fixedly connected to the two sides of the connecting pipe. According to the device, the installed self-locking servo motor is powered off, the connection pipe can be rapidly separated from the air pipe through the reset force of the first reset spring, when the connection pipe is separated from the air pipe, the multiple elastic sealing pieces can automatically reset, the air pipe is sealed, through sealing of the air pipe, continuous operation of the arc spray gun is avoided, and the use safety of the arc spray gun is guaranteed.

Description

technical field [0001] The invention relates to an electric arc spray gun, in particular to an electric arc spray gun with a protective structure, which belongs to the technical field of electric arc spray guns. Background technique [0002] Arc spraying is a technology that uses an arc burning between two continuously fed metal wires to melt metal, atomizes the molten metal with high-speed airflow, and accelerates the atomized metal particles to spray them to the workpiece to form a coating. . Arc spraying is the most commonly used thermal spraying method in practical application engineering such as steel structure anti-corrosion, wear resistance and mechanical parts maintenance. The arc spraying system is generally composed of a special power supply for spraying, a control device, an arc spray gun, a wire feeder and a compressed air supply system. [0003] The current arc spraying is generally sprayed by an arc spray gun, but the current arc spray gun does not have a pro...
