Anti-blocking processing system for welding gun nozzles for carbon dioxide arc welding

Abstract

An anti-blocking processing system for welding gun nozzles for carbon dioxide arc welding is used for solving the blocking problem of the welding gun nozzles for the carbon dioxide arc welding. The anti-blocking processing system for the welding gun nozzles for the carbon dioxide arc welding comprises a liquid storage tank, a splash-proof liquid spraying device, welding gun placing supports and a PLC (Programmable Logic Controller) control mechanism; the liquid storage tank is filled with splash-proof liquid; a compressed air inlet pipe is arranged at the top of the liquid storage tank; liquid outlet pipes are arranged at the bottom of the liquid storage tank; the splash-proof liquid spraying device comprises a group of splash-proof liquid spraying units which are in series connection with the liquid outlet pipes of the liquid storage tank; the number of the splash-proof liquid spraying units is matched with that of welding guns in welding production lines; movements of the splash-proof liquid spraying units are controlled by the PLC control mechanism; the welding gun placing support is arranged at the tail end of every splash-proof liquid spraying unit. The anti-blocking processing system for the welding gun nozzles for the carbon dioxide arc welding has the advantages of reducing labor intensity of operators, improving welding production efficiency, effectively avoiding the welding gun nozzles from blocking caused by splashing of welding slags and poor electric conduction between a contact nozzle and a welding wire and caused by a processing method of dipping anti-blocking paste and satisfying a workpiece requirement for welding quality.

Description

technical field [0001] The invention relates to a welding auxiliary system, especially a CO 2 The invention relates to an anti-clogging treatment system for a gas shielded welding torch nozzle, which belongs to the field of welding technology. Background technique [0002] CO 2 Gas shielded welding is widely used in rolling stock, automobile, shipbuilding and other industries due to its advantages of low welding cost, high production efficiency, good welding quality, wide application range and conducive to the realization of welding process automation. CO 2 Gas shielded welding uses the arc between the welding wire and the weldment as the heat source to melt the welding wire and the base metal, and deliver CO to the welding area 2 Shielding gas that protects the arc, molten wire, weld pool, and nearby parent metal from the oxidizing effects of the surrounding air. CO 2 Welding equipment for gas shielded welding includes robotic automatic welding equipment and semi-autom...

Problems solved by technology

Although the technical solution of this patent solves the problem of the blockage of the MIG shielded welding torch, it is a manual operation equipment for a single welding torch, and cannot realize automatic induction spraying of multiple welding torches at the same time, and it is difficult to realize the automatic control of the welding production line body ; and the adoption of this patented technical solution requires the welding torch to be put into the spray container, and it must be kept in a hand-held state, which increases the labor intensity of the operator
