Argon arc welding device for cambered butt joint with square aluminum tube

Abstract

The invention relates to an argon arc welding device for cambered butt joint with a square aluminum tube. The device includes a rack, a protective box is arranged on the inner bottom of the rack, a hydraulic cylinder is arranged in the protective box, a piston rod is arranged on the upper portion of the hydraulic cylinder, a guiding shell is arranged on the end portion of the piston rod, a pair ofguiding rails are arranged between the inner side of the rack and the outer side of the protective box, and a moving base is arranged on the guiding rails; a rotary motor and an argon arc welding machine are arranged on the moving base, a rotating shaft is arranged on the upper portion of the rotary motor, a rotary base is arranged on the end portion of the rotating shaft, the top of the rotary base is provided with a rotating column, a locating pipe is arranged on the end portion of the rotating column and internally provided with an adjusting pipe, and an argon arc welding head is arrangedon the end portion of the adjusting pipe; a connecting pipe is connected to the rear end of the adjusting pipe, the argon arc welding head is connected to one end of the connecting pipe, and the otherend of the connecting pipe is connected to the argon arc welding machine. The argon arc welding device greatly improves the efficiency of argon arc welding of the square aluminum tube, the argon arcwelding head can be horizontally rotated and adjusted, and the flexibility of argon arc welding performed on the square aluminum tube is significantly improved.

Description

technical field [0001] The invention relates to an argon arc welding device, in particular to an argon arc welding device for butt jointing of aluminum squares. Background technique [0002] Argon arc welding is tungsten inert gas shielded arc welding, which refers to a welding method in which industrial tungsten or active tungsten is used as non-melting electrode and inert gas is used as shield. Argon arc welding machines are divided into two types: melting electrode argon arc welding machines and non-melting electrode argon arc welding machines according to the different electrodes. Non-melting electrode argon arc welding is that the arc burns between the non-melting electrode and the workpiece, and an inert gas that does not chemically react with the metal flows around the welding arc to form a protective gas cover, so that the tungsten electrode tip, the arc and the melting The pool and the metal already at high temperature are not in contact with the air, which can pre...

AI Technical Summary

Problems solved by technology

The existing argon arc welding machine is inconvenient to butt the aluminum square, the welding operation efficiency of the aluminum square is low, and the efficiency of the argon arc welding operation is low
