Description
Technical field
The present invention relates to electron beam gun technical field, more particularly to a kind of electron beams rifle deflected joint and its use
Method.
Background technology
It is currently used for welding, evaporates and all kinds of axial electron guns of melting purposes, also known as electron beam gun.Produced from electronics
Position is nearly all beeline channel to stream outlet, either traditional hot-cathode electric beam rifle still newer cold cathode gas
Electron Beam Produced by Gas Discharge rifle.
The benefit of this axial arrangement is that whole electron gun rifle is compact-sized, and beam direction is concentrated, and is easy to focus on and is scanned.
But shortcoming is also apparent from simultaneously.Because the outlet of electron gun is exposed to stove towards face vacuum chamber, each part in electron gun inside
Under room environmental pollution.During electron gun use, caused each metalloid and nonmetallic steam, splashing due to material heating
The impurity such as thing, it can also be easy to inside entrance electron gun straight（The disadvantage of linear structure）, it is deposited on zero, electron gun
Part surface, pollution rifle room, the reduction of high-voltage isulation performance is caused, triggers accidental discharge, influences electron gun job stability.Pollution is tight
Splash can even fall in the gap for needing high-voltage isulation during weight, directly contribute partial high pressure electric discharge, burn inside electron gun
Part.Therefore, this evaporant and splash, which how is reduced or avoided, just turns into raising electron gun to the pollution inside electron gun
One of key of job stability.
Existing method substantially has following two：A kind of is to be built between electron gun and furnace chamber with the method for micro inflation
One relative high-pressure area, forms certain pressure retardance to steam.This method shortcoming is that mechanism is complicated, it is necessary to extra a lot
Inflation, extraction sector, and influence electron gun working vacuum of not taking pains is controlled, cause to discharge in rifle.Another method is pair
Rifle room is vacuumized by force, and steam is siphoned away with higher vacuum.This method is most to be carried out using additional vacuum pumps, is also deposited
In the shortcomings that complicated, cost is high.The common drawback of both approaches be no matter which kind of method, the splashing for bulky grain is all
It is helpless, and for the evaporation of steam, also act on limited.
The content of the invention
To the above-mentioned state of the art, the technical problems to be solved by the invention are to provide one kind
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of electron beams rifle deflected joint, including
Deflection tube, the deflection tube upper end are provided with upper flange, and lower end is provided with lower flange, deflection coil is cased with outside the upper flange, described
Focus coil, scanning coil are cased with successively from top to bottom outside lower flange, and temperature probe is inserted with the lower flange.
Further, delivery port is provided between the deflection tube and upper flange, is provided between the deflection tube and lower flange
Water inlet.
Further, the upper flange is provided with electron gun outlet(discharge) flange.
Further, it is provided with sealing ring between the upper flange more than the electron gun outlet(discharge) flange.
Further, the lower flange lower end is provided with body of heater electron gun interface.
A kind of electron beams rifle deflected joint application method, it is characterised in that comprise the following steps：
（1）Regulation needs to use the electron beam of the electron gun of deflected joint to project direction first, it is projected along center；
（2）Electron gun, deflected joint and vacuum furnace body are connected, subsequent start-up vacuum system, body of heater and electron gun are extracted into work
Vacuum；
（3）Starting electron gun, regulation accelerating potential is slowly increased beam power to 0.01 ~ 0.4kW to normal operating value, by
The current value of the deflection coil of step increase deflected joint（When using the deflected joint with temperature measuring equipment, can be become with temperature measurement data
It is turned to the foundation whether electron beam is irradiated to deflected joint side wall.When its temperature rises, continue to increase yoke current,
Until it is not increasing）, while electron beam in close observation furnace chamber, until the electron beam of deflected joint outlet projects from center；
（4）The current value of the simultaneously deflection coil of fixed deflection joint is recorded, same accelerating potential corresponds to same in use
Deflection current；
（5）Start normal use.
Compared with prior art, the advantage of the invention is that：After deflected joint, by the electron beam quilt of electron gun injection
The deflection coil of deflected joint enters back into vacuum container after deflecting an angle, avoided from structure various steam in furnace chamber,
Splash is to the direct projection inside electron gun.The pollutants such as most steam and splashing are made all to be deposited on deflected joint inwall, from
And protect inside the electron gun for needing high-cleanness environment, greatly improve electron gun job stability.
