A wire feeding device for surfacing welding of sealing surface

Abstract

The invention relates to a wire feeding device for surfacing welding on a sealing surface, which effectively solves the problems of unstable wire feeding system and poor versatility; The wire outlet end is provided with a liquid outlet pipe, and also includes a liquid tank. The liquid tank is filled with viscous fluid. Both the liquid outlet pipe and the liquid inlet pipe are connected with the liquid tank. A first shell is connected to the end, and the welding wire passes through the wire guide tube and then penetrates into the first shell. The inner wall of the first shell is provided with a plurality of nozzles, and the nozzles spray water to wash the welding wire, and the lower end of the first shell is connected There is a second shell, and the welding wire passes through the first shell and then penetrates into the second shell. The side wall of the second shell is equipped with an air intake pipe, and the intake pipe introduces hot dry air into the second shell to dry the welding wire. Dry, the side wall of the second shell is provided with an air outlet; the wire feeding speed of the present invention is stable, and can be applied to various types of welding wires, and has strong versatility.

Description

technical field [0001] The invention relates to the field of surfacing welding, in particular to a wire feeding device for surfacing welding on a sealing surface. Background technique [0002] Valves are widely used in various fields of the national economy. In order to improve the durability and stability of the valve, high-strength alloys are generally surfacing on the valve sealing surface to improve its wear resistance, corrosion resistance and other properties; In all kinds of automatic surfacing equipment, the wire feeding system is indispensable to send the welding wire to the welding position at a stable speed. The current wire feeding system generally feeds the wire through the wire feeding wheel. Pull-type wire feeding system and push-pull wire-feeding system; the wire feeding method of the wire feeding wheel concentrates the wire feeding force in one position. The wire speed is unstable, and it is prone to slippage; in addition, a wire feed wheel can only be perf...
