Abstract
The utility model relates to a plasma welding cutting gun, which is applicable to plasma flame brazing with high fire power and plasma flame cutting for thick plates. The plasma welding cutting gun is provided with a high-pressure gas channel, a gas channel allowing welding cutting high-pressure gas to pass through is arranged at the centers of a cathode post and a cathode, and the cathode is formed by inlaying annular emission electronic electrode metal into a copper seat.
Description
Technical field
The plasma welding field is field newly developed, and relatively original gas welding cutting has superior energy-saving effect and safety and environmental protection effect.
Background technology
In existing plasma welding technology, minute plasma arc-welding and plasma cutting; The plasma torch soldering also is the technology that I have have just researched and developed comparative maturity, since the soldering work piece more complicated, the soldering narrow space, so plasma torch brazing gun head volume is little, cause cooling capacity restricted, can not be used for large electric current, high flame soldering work piece; The air plasma cutting is used more extensive, and shortcoming is that the cutting koniology is too large, work under bad environment, and the 2nd, the cutting slab needs high-current supply, and scarfing is uneven.
Summary of the invention
The present invention addresses the above problem, the plasma solder cutting gun, comprise rifle body, nozzle, negative electrode, cathode column, insulating ceramics, high-temperature insulation glue, free motive body passage is arranged in the middle of negative electrode and the cathode column, the annular electron emission metal that negative electrode is inlayed by copper seat and copper seat bottom forms.Electron emission metal (hafnium or zirconium).
Description of drawings:
Fig. 1 is plasma solder cutting gun master cutaway view of the present invention
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated: as shown in Figure 1, the plasma solder cutting gun is comprised of the insulating cement 3 between rifle body 6, cathode column 2, negative electrode 12, nozzle 9, insulating ceramics 7, rifle body and the cathode column; Cooling-water duct 5, water inlet 4, delivery port 14 and arc maintenance air inlet 13 are arranged in the rifle body 6; Between nozzle 9 and the negative electrode 12 arc ignition room 8 is arranged; Cathode column 2 has air inlet 1; The annular electron emission electrode metal 10 that negative electrode 12 is free motive body passage 11 and inlays.The plasma solder cutting gun is after striking, when being used for the plasma torch weldering, regulating the arc maintenance mixing and contain the alcohols inflammable gas, electric arc is in the outer of negative electrode 12 and the inwall stable maintenance of nozzle 9, and the plasma-arc flame that under the effect of arc maintenance gas, forms, from nozzle 9 ejections; Mix and to contain the gas passage 11 of alcohols compressed air from the air inlet 1 of cathode column 2 to negative electrode 12, go out nozzle 9, flash fire discharges amount of heat, satisfies large workpiece soldering demand; Because electric arc is that gas can not thrust electric arc at the outer of negative electrode 12 and the inwall of nozzle.And when being used for the plasma cutting, regulating the arc maintenance mixing and contain the alcohols inflammable gas, electric arc is in the outer of negative electrode 12 and the inwall stable maintenance of nozzle 9, and the plasma-arc flame that forms under the effect of arc maintenance gas, from nozzle 9 ejections; Thick workpiece is carried out preheating, after thick workpiece is preheated, open the gas passage 11 of gases at high pressure from the air inlet 1 of cathode column 2 to negative electrode 12, go out nozzle 9, the material of the pre-heat fusing of workpiece is blown open, form neat scarfing one.Such cutting operation air consumption is little, can not cause a large amount of dusts, because preheating being arranged, the passage of negative electrode 12 is little, so can cut thick workpiece with little electric current, scarfing is also neat.
