A kind of argon arc welding machine with heat dissipation function and its working method

Abstract

The invention discloses an argon arc welding machine with a heat dissipation function and a working method thereof. The argon arc welding machine includes an operating table, a fixed plate, a bracket and a welding torch, and a second cylinder is fixedly installed at the center of one side of the fixed plate. A push rod is fixedly installed on the piston rod of the second cylinder; the present invention drives the push rod through the second cylinder to push the two movable plates to move to the middle, and the pipe fittings are fixed by the two clamps, otherwise the pipe fittings can be loosened, which is convenient for fixing and Loosen the pipe fittings to avoid manual fixation and easy loosening, which can reduce labor intensity and improve work efficiency; the first cylinder drives the telescopic rod of the cylinder to push the sliding plate to move to the right, thereby pushing the pipe fittings to slide to the right, and the pipe fittings can be roughly adjusted in a large range The second screw rod drives the sliding plate to push the pipe fittings to slide to the right, so that precise adjustment in a small range can be performed, the positioning of the pipe fittings can be made more accurate, the positioning will not deviate, it is easy to weld, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of argon arc welding machines, in particular to an argon arc welding machine with heat dissipation function and its working method. Background technique [0002] The argon arc welding machine is a machine using argon arc welding, which adopts the arc starting method of high voltage breakdown. Argon arc welding is tungsten inert gas shielded arc welding, which refers to the welding method that uses industrial tungsten or active tungsten as non-melting electrode and inert gas (argon) as protection, referred to as TIG. It is generally used for the welding of thin plates of 6-l Omm and the back welding of single-sided welding and double-sided forming of thick plates. [0003] In the patent No. CN106112218B, a tube plate argon arc welding machine is disclosed. The welding wire between the wire feeder and the wire guide nozzle on the welding torch of this patent will not be wound on the rotating shaft, but the ar...

Problems solved by technology

[0003] In the patent No. CN106112218B, a tube plate argon arc welding machine is disclosed. The welding wire between the wire feeder and the wire guide nozzle on the welding torch of this patent will not be wound on the rotating shaft, but the argon arc welding machine still exists. The defects mentioned above: 1. It does not have the function of fixing the pipe fittings through the clamp driven by the cylinder. Manually fixing the pipe fittings will cause the pipe fittings to loosen easily during the welding process, and deviations will occur, resulting in low welding quality; The function of adjusting the position and then adjusting the accuracy in a small range leads to inaccurate positioning; 3. The position of the welding torch is not easy to adjust, and it is not easy to operate and use. At the same time, the heat dissipation effect is poor, and the cooling time of the pipe fittings is long, resulting in low work efficiency.
