Abstract

The invention discloses an anti-power-failure arc spraying gun, and belongs to an arc spraying or spray welding device. The anti-power-failure arc spraying gun comprises a spraying gun body and a spraying gun seat, the spraying gun body is mounted on the spraying gun seat, at least one guide wire tube and a compressed air tube are arranged inside the spraying gun seat, and an opening at the front end of the spraying gun body is corresponding to an opening of each guide wire tube; shells are fixed at the positions, corresponding to inlets of the guide wire tubes, at the rear end of the spraying gun seat; the other end of each shell is connected with a terminal pad, and an electrode bundle corresponding to the inlet of each guide wire tube is mounted on each terminal pad. Electroconductive assemblies are adopted to conduct electricity in a mode of axially wrapping metal wires, the spraying gun is ensured to form continuous electricity conduction in use by a mode of electrode wire contact, and accordingly arc breaking caused by power failure is avoided; besides, the metal wires can freely move between the electrode bundles by the axial wrapping mode; in addition, through the vertically-symmetrical guide tubes and electroconductive assemblies, spraying arc breakage can be further prevented.

Description

[0001] technical field [0002] The present invention relates to an electric arc spraying or spray welding equipment, more specifically, the present invention mainly relates to an electric arc spray gun resistant to power failure. [0003] Background technique [0004] At present, in the existing metal wire arc spraying gun with a wire pushing device, its conduction is performed by a conductive tip and a conductive rod. Among them, there is a straight round hole in the middle of the contact tip and the conductive rod, which is slightly larger than the diameter of the metal wire. The metal wire passes through the wire pushing device, the wire feeding tube, the conductive rod, and the conductive tip in sequence, and then the arc is sprayed. Because the diameter of the straight round hole is slightly larger than that of the wire, and the diameter of the hole becomes larger after wear, there is a gap between them, and the contact between the contact tip and the wire is actually...
