Sealing surface surfacing welding wire feeding device

Abstract

The invention relates to a sealing surface surfacing welding wire feeding device. The problems that a wire feeding system is unstable and poor in universality are effectively solved. According to the technical scheme, the device comprises a wire guide pipe, a liquid inlet pipe is arranged at the wire inlet end of the wire guide pipe, a liquid outlet pipe is arranged at the wire outlet end, the device further comprises a liquid box, viscous fluid is contained in the liquid box, the liquid outlet pipe and the liquid inlet pipe both communicate with the liquid box, a liquid pump is arranged on the liquid outlet pipe, the wire outlet end of the wire guide pipe is connected with a first shell body, a welding wire penetrates out of the wire guide pipe and then penetrates into the first shell body, a plurality of spray heads are arranged on the inner wall of the first shell body, the spray heads spray water to wash the welding wire, the lower end of the first shell body is connected with a second shell body, the welding wire penetrates out of the first shell body and then penetrates into the second shell body, an air inlet pipe is installed on the side wall of the second shell body, the air inlet pipe introduces hot dry air into the second shell body to dry the welding wire, and air outlet holes are formed in the side wall of the second shell body. The wire feeding device is stable in wire feeding speed, can be suitable for welding wires of various models and is high in universality.

Description

technical field [0001] The invention relates to the field of surfacing welding, in particular to a sealing surface surfacing welding wire feeding device. Background technique [0002] Valves are widely used in various fields of the national economy. In order to improve the durability and stability of valves, high-strength alloys are generally surfacing on the sealing surface of valves to improve various properties such as wear resistance and corrosion resistance; In all kinds of automatic surfacing welding 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, which is divided into push wire feeding system, Pull type wire feeding system and push-pull type wire feeding system; the wire feeding mode of the wire feeding wheel concentrates the wire feeding force at one position, and when feeding thinner and softer welding wire,...
