Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a plasma cutting gun. Background Art

[0002] Plasma cutting is a method of "decomposing" or ionizing air through an electric arc to become basic atomic particles, thereby generating a plasma arc. During cutting, a high-temperature, high-speed plasma fluid formed by compressing the arc through a small-aperture nozzle is used as a heat source for melting and cutting.

[0003] After searching, in the prior art, a Chinese patent with patent announcement number CN217096112U discloses "a plasma cutting gun, comprising a shell, a gun head, an electrode, a first wire, an air pipe and a temperature sensor, the gun head is installed in the shell, an electrode seat is provided at the first end of the gun head, the electrode seat has an outlet hole for spraying gas, the electrode is installed in the electrode seat, the air pipe is passed through the shell and extends to the interior of the gun head, and is used to spray gas to the outlet hole, the first wire is electrically connected to the electrode, the temperature sensor is used to detect the real-time temperature of the gun head, after the plasma cutting gun finishes cutting, the air pipe continues to supply cooling gas, the temperature sensor detects the real-time temperature of the gun head, and when it is detected that the temperature of the plasma cutting gun drops to a normal range, the gas supply is stopped to avoid waste of cooling gas and dust pollution."

[0004] However, there are still the following defects: the height of the nozzle cannot be limited and supported and adjusted during the cutting process of the workpiece, and the worker cannot accurately control the distance between the nozzle and the workpiece when using it, which easily leads to overheating of the nozzle and greatly reduces the service life of the nozzle. For this reason, we propose a plasma cutting gun. Utility Model Content
