Plasma water spray cutting gun

Abstract

The invention discloses a plasma water spray cutting gun which comprises a cutting gun body. The cutting gun body is provided with a shell, an insulating cylinder, a conductor, an electrode, a distributor and a nozzle, and the insulating cylinder, the conductor, the electrode, the distributor and the nozzle are assembled in the shell. A gap area between the distributor and the electrode serves as an airflow distribution channel, the nozzle is arranged at the bottom of the distributor, an air inlet channel is disposed in the conductor, the nozzle and the periphery of the bottom end of the electrode form an air outlet channel, the bottom end of the nozzle is provided with a plasma flame ejection hole, and the air inlet channel, the airflow distribution channel, the air outlet channel and the plasma flame ejection hole are sequentially communicated to form an airflow channel; a water spray ejecting hole is formed in the portion, opposite to the plasma flame ejection hole, of the bottom of the shell, a water spray generation channel is formed in the cutting gun body, and the water spray ejection hole is communicated with the water spray generation channel. The plasma water spray cutting gun can achieve plasma cutting of parts to be cut, can cool the parts to be cut in a water-cooling mode at the same time, avoids smoke, dust, strong light and harmful gas generated in the cutting process, and improves environmental friendliness during cutting.

Description

technical field [0001] The invention relates to a plasma water mist cutting gun. Background technique [0002] At present, the structure of the general plasma arc cutting torch is mainly to connect the electrode and the nozzle to the two poles of the power supply respectively. [0003] The arc burns between the electrode and the nozzle, and after the working gas is continuously fed through the arc space, it becomes a high-temperature plasma flame jetted from the nozzle. However, the sintered ceramic parts of the nozzles of plasma cutting torches on the market are easy to burst, which will cause the burning of the entire torch body. If the cutting torch is replaced, it will increase the cost and reduce the cutting efficiency. To effectively cut carbon steel and non-ferrous metal materials, people often use plasma cutting guns for operations, but this operation often produces smoke, strong light and harmful gases, and the electrodes and nozzle parts are easy to burn out.

However, the sintered ceramic parts of the nozzles of plasma cutting torches on the market are easy to burst, which will cause the burning of the entire torch body. If the cutting torch is replaced, it will increase the cost and reduce the cutting efficiency. For effective cutting of carbon steel and non-ferrous metal materials, people often use plasma cutting guns for operations, but this operation often produces smoke, strong light and harmful gases, and the electrodes and nozzle parts are easy to burn out.
