TIG wire feeding pen

Abstract

A TIG wire feeding pen comprises a heat dissipation pen point, a wire feeding switch, a speed reducer, a wire feeding wheel, a pen shell, a mini type shell, an electric quantity display, a speed regulator, a charging interface, a welding wire guide pipe, a chargeable battery, guide wheels, a pressure adjuster, a battery replacing window and a wire feeding wheel replacing window. The mini type motor and the speed reducer are connected with the wire feeding wheel and provide power for wire feeding, and continuous or different-step-size stepping wire feeding is achieved by replacing circular or different-arc-length fan-shaped wire feeding wheels. The pressure adjuster is used for adjusting the pressure of the guide wheels, and welding wires different in diameter are conveyed out. The wire feeding speed is adjusted through the speed regulator, wire feeding is controlled through the wire feeding switch, and the electric quantity display monitors the residual electric quantity. The heat dissipation pen point is made of a material good in heat conduction coefficient, and welding wire heat dissipation is facilitated. The TIG wire feeding pen is convenient to carry, the labor intensity of workers is relieved, the problem about stability, consistency and accuracy of TIG manual wire feeding is solved, and the welding line formability and production efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a wire feeding equipment used for manual TIG welding. Background technique [0002] At present, manual TIG welding (Tungsten Inert Gas Welding, non-melting inert gas tungsten shielded welding) is widely used in the welding of pressure vessels, pipes and stainless steel plates due to its flexible operation and high weld quality. It is also often used in classroom teaching and has an irreplaceable role in automatic TIG welding. When performing manual TIG welding, it is often necessary to fill the welding seam with welding wire, and usually use a straight welding wire with a length of about 1000mm and a specification of Φ2~Φ4mm. During the welding process, the wire feeding is completed by the welder twisting the welding wire with his fingers. In order to achieve beautiful, uniform and high-quality fish scale welds, etc., the welder is required to feed the weld...

AI Technical Summary

Problems solved by technology

During the welding process, the wire feeding is completed by the welder twisting the welding wire with his fingers. In order to achieve beautiful, uniform and high-quality fish scale welds, etc., the welder is required to feed the welding wire stably and evenly, which is very important for new students or ordinary workers. It requires a lot of practice to master, and the uniformity and stability of manual wire feeding are poor, the labor intensity is high, the welding efficiency is low, and the weld shape is difficult to control

Most of the existing automatic wire feeders are connected with the welding torch as a whole, with large volume and mass, suitable for automatic welding and not easy to carry and maintain
