Abstract

The invention 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

The plasma welding burning torch
Technical field
Plasma welding field is field newly developed, and original relatively combustion gas welding has superior energy-saving effect and safety and environmental protection effect.
Background technology
In existing plasma welding technology, divide the cutting of plasma arc-welding and plasma; The plasma torch soldering also is the technology that I have have just researched and developed comparative maturity, because the soldering work piece more complicated, the soldering space is narrow and small; So plasma torch soldering gun head volume is little; Cause cooling capacity restricted, can not be used for big electric current, big firepower soldering work piece; The air plasma cutting is used more extensive, and shortcoming is that the cutting koniology is too big, 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, and in the plasma soldering gun head of my former invention, increases a gases at high pressure passage to negative electrode and cathode column center, and negative electrode is made the copper seat and inlayed annular emission electronics electrode metal (hafnium or zirconium) structure.
Description of drawings:
Fig. 1 is a plasma welding burning torch master cutaway view of the present invention
Elaborate below in conjunction with the accompanying drawing specific embodiments of the invention: as shown in Figure 1, the plasma welding burning torch is made up 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 high pressure admission mouth 1; Negative electrode 12 has gases at high pressure passage 11 and inlays annular emission electronics electrode metal 10.The plasma welding burning torch 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 a large amount of heats, satisfies big workpiece soldering demand; Because electric arc is that gases at high pressure 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 under the effect of arc maintenance gas, forms, from nozzle 9 ejections; Thick workpiece is carried out preheating, after thick workpiece preheating is good, open the gas passage 11 of gases at high pressure, go out nozzle 9, blow the material of workpiece preheating fusing open, form neat scarfing one from the air inlet 1 of cathode column 2 to negative electrode 12.Such cutting operation air consumption is little, can not cause a large amount of dusts, because preheating is arranged, the passage of negative electrode 12 is little, so can cut thick workpiece with little electric current, scarfing is also neat.

Claims (2)

1. the plasma welding burning torch comprises rifle body, nozzle, negative electrode, cathode column, insulating ceramics, and high-temperature insulation glue is characterized in that: free motive body passage is arranged in the middle of negative electrode and the cathode column.
