A gas shielded welding torch that can be adjusted in multiple directions

Abstract

The invention discloses a multi-directional adjustable gas shielded welding torch, which belongs to the field of welding. A multidirectional adjustable gas shielded welding torch includes a handle, a connecting pipe and a shield. The connecting pipe includes a snake bone pipe group, a snake The bone tube group includes a plurality of snake bone tubes connected head to tail. The snake bone tube has a built-in wire feeding hose. The snake bone tube is sleeved with a flexible outer tube. One end of the snake bone tube is provided with a spherical end. One end is provided with a spherical groove matching the spherical end, and the two sides of the spherical end are symmetrically provided with a spring leaf, and an arc-shaped insert is fixed on the spring leaf, and the two sides of the spherical groove are provided with an arc corresponding to the arc-shaped insert. Shaped slot, the invention has a simple structure, and uses the mutual cooperation between the magneto-rheological fluid and the welding wire to pass through the electromagnetic field to achieve the purpose of locking the snake-bone tube without an additional locking mechanism, which can meet the angle adjustment requirements of different welding dead angles. It is convenient to use, has a market prospect and is suitable for promotion.

Description

technical field [0001] The invention relates to the field of welding, and more specifically relates to a gas shielded welding torch which can be adjusted in multiple directions. Background technique [0002] Gas shielded welding refers to the welding method of carbon dioxide or argon shielding, without welding rods and welding wires. CO2 welding has high efficiency, and argon shielded welding mainly welds aluminum, titanium, stainless steel and other materials. [0003] In gas shielded welding, the welding wire is fed into the arc by the wire feeder through the welding torch, and the welding torch passes the welding current and is exposed to the arc, which is easily damaged by heating or difficult to operate. Especially the parts that are directly heated by the arc, such as the contact tip, the nozzle and the insulating part with low heat resistance, such as the cable sheath and the gas pipe, are more easily damaged, which becomes the key factor affecting the life of the we...

[0003] In gas shielded welding, the welding wire is fed into the arc by the wire feeder through the welding torch, and the welding torch passes the welding current and is exposed to the arc, which is easily damaged by heating or difficult to operate

Especially the parts that are directly heated by the arc, such as the contact tip, the nozzle and the insulating part with low heat resistance, such as the cable sheath and the gas pipe, are more easily damaged, which becomes the key factor affecting the life of the welding torch and the stability of the welding process. At the same time, the existing Most of the welding torches are in the form of fixed elbows. When encountering special welding angles, they cannot be adjusted and the construction is difficult. Therefore, we propose a gas shielded welding torch that can be adjusted in multiple directions to solve the above problems.
