FLUX SUPPLY EQUIPMENT FOR ELBOW PIPE AUTOMATIC WELDING EQUIPMENT

摘要

PURPOSE: A flux feeder for an automatic elbow tube welding device is provided to automatically feed flux to a welded portion and collect the used flux. CONSTITUTION: A flux feeder for an automatic elbow tube welding device comprises a hopper(110), a drying unit(120), a flux tank(140), a solenoid valve(150), and a collecting unit. The hopper is installed on the top of a bed, to which flux is provided. The drying unit is connected to the hopper and heats the provided flux to dry. The flux tank is installed on the top of the welding nozzle and connected to the drying unit, and stores the flux provided from the drying unit and supplies the stored flux to a welding nozzle. The solenoid valve is installed in a coupling hose(164) between the welding nozzle and the flux tank and supplies a fixed amount of flux to the welding nozzle. The collecting unit draws in the flux provided along a weld line(3) of an elbow tube(2) and returns the drawn flux to the hopper.
