Example Embodiment

[0039] The present invention will now be described in detail with reference to the drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic way, so it only shows the structure related to the present invention.

[0040] See figure 1 with figure 2 The present invention provides a plasma arc cutting torch. The plasma arc cutting torch includes a torch body 10, a sleeve assembly 20 sheathed outside the torch body 10, and a protective cover 30 installed at the lower end of the torch body 10. When the plasma arc generated by the plasma arc cutting torch is directed to the surface of the workpiece (for example, stainless steel or aluminum), the particles inside the plasma arc generate a huge bombardment force on the surface of the workpiece, releasing a large amount of heat, and the temperature generated by the high temperature of the arc The workpiece material at the plasma arc is partially melted and v...

Abstract

The invention discloses a plasma arc cutting torch. The plasma arc cutting torch comprises an insulating part, an electrode base accommodated in the insulating part, an electrode arranged at the lowerend of the electrode base, and a distributor and a nozzle which are arranged outside the electrode in a sleeved mode; the distributor is positioned between the insulating part and the nozzle, an airguide groove is arranged between the insulating part and the electrode base, the air guide groove is a spiral groove, an ion airflow chamber is arranged between the nozzle and the electrode, the distributor is provided with a distribution hole, the distribution hole penetrates through the inner side and outer side of the distributor, the central axis of the distribution hole and the central axis of the distributor are arranged in a staggered mode, and the distribution hole is communicated with the gas guide groove and the ion air flow chamber. According to the plasma arc cutting torch, the primary compression of the working gas is realized under the action of the gas guide groove, the secondary compression is realized under the action of the distribution hole, so that the energy of the arccolumn is improved, in addition, the plasma arc is emitted to the workpiece in a vortex mode, and thus the flatness of the cut in the cutting process is ensured.

Description

technical field [0001] The invention relates to the technical field of plasma welding and cutting, in particular to a plasma arc cutting torch. Background technique [0002] The cutting torch is an important tool for gas welding. When working, the cutting torch generates a plasma arc and shoots at the surface of the workpiece. The particles inside the plasma arc have a huge impact on the surface of the workpiece, releasing a large amount of energy to partially melt and vaporize the material of the workpiece, thereby forming an incision. , to implement the cutting function. During the actual cutting operation, when the operator controls the cutting torch, it is inevitable that the cutting torch will rotate along the axis of the cutting torch. Insufficient gas compression and low arc column energy affect the cutting quality. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems i...
