The electron gun is at a welding position of a to-be-welded workpiece in one welding chamber when in the working state, the opening and closing door of the welding chamber is opened, and the opening and closing doors of the other welding chambers are closed. The efficient electron beam welding device has the advantages that auxiliary waiting time for part replacement, vacuum acquisition and the like is utilized effectively, working efficiency of the electron beam welding device is improved greatly, and the efficient electron beam welding device has obvious technical advantages and remarkable economic benefit.
Description
Technical field
The utility model belongs to the electron beam welding device, is specifically related to the high efficent electronic bundle welder of a kind of welding job efficient.
Background technology
Electron beam welding is to utilize the high-voltage electrostatic field that the electronics of hot cathode emission is converged to electron beam, becomes the high fleck of an energy density (generally to reach 10 through electromagnetic focusing
5～8W/cm
2), the bombardment welded piece melts the metal of weld seam both sides rapidly, realizes a kind of technology of welding purpose.The electron-beam welder that uses generally partly is made up of electron gun, high voltage source, vacuum unit, vacuum welding chamber, electric control system, frock clamp and workbench running gear etc. at present.Characteristics such as it has without welding rod, weld seam is dark and narrow, the heat affected area is little, weldering speed high and the weldering road is controlled, thereby that weld seam is pure, depth-to-width ratio is big, the sweating heat deflection is little, technological parameter is adjustable is controlled, computer numerical control operation, welding product qualification rate height, and the advantages such as workpiece that can weld refractory metal (for example tungsten, tantalum, niobium etc.) different melting points (for example copper and tungsten etc.), different-thickness.Because electron gun is operated under the high pressure conditions, before injecting workpiece, cause energy loss and electron beam divergence with other gas molecule collisions in order to reduce electronics simultaneously, electron gun and welding booth all must operate under certain vacuum state.Vacuum workshop creates high pure environment for welding, thereby the gas that do not need protection just can obtain non-oxidation, pore-free and not have the high-quality welded joint of slag inclusion.
In the prior art, electron beam welding equipment is after the electron beam welding of carrying out a workpiece, need open vacuum workshop, carry out the replacing of workpiece, and then work the time vacuumized processing, carry out electron beam welding, the inefficiency of this kind welding equipment, the most of the time of electron gun all is in wait state, and the effective operation time only accounts for 20%.
The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides a kind of reasonable in design, can significantly improve the efficent electronic bundle welder of electron beam welding device operating efficiency.
For achieving the above object, the utility model provides a kind of efficent electronic bundle welder, it comprises electron gun, described electron gun lower end is provided with ball seat, this electron gun is erected on the prechamber by this ball seat, the electron beam ejecting end of this electron gun is positioned at this prechamber, and described prechamber is communicated with at least two welding booths; Be respectively arranged with open and close door between described welding booth and the prechamber, described electron gun is under a duty, and it is in the welding position of workpiece to be welded in the welding booth, and the open and close door of this welding booth is opened, the open and close door closure of other welding booth.
Preferable, be provided with sealing bearing bush between described ball seat and prechamber outer wall.
Preferable, described gun arm is located on the end face of described prechamber, offers the open and close door of first welding booth and second welding booth corresponding with the electronics ejecting end of electron gun on the opposing end surface of this prechamber.
Preferable, first welding booth and second welding booth are set up in parallel, and described first welding booth and second welding booth are respectively arranged with the more opening/shutting controller of changing device, vaccum-pumping equipment and open and close door of workpiece to be welded.
Preferable, the open and close door place of described welding booth is provided with the baffle plate valve port.
The beneficial effects of the utility model are: the utility model can electron gun can be adjusted the direction of electron beam ejecting end by described ball seat under vacuum state, finish the conversion of electron beam between the welding booth, realize the multistation motion of electron gun on prechamber, electron beam can be switched between two welding booths, when a welding booth is in welded condition therein, another welding booth begins to finish and opens, change workpiece, close and forvacuum and etc. work to be welded, each welding booth open and close door identical with prechamber is single open control, namely have only the open and close door that meets a welding booth of welding requirements after the forvacuum to be in open mode, so can guarantee the vacuum in the prechamber, and the realization electron gun that the continues weld job that carries out electron beam welding in a plurality of welding booths.
This efficent electronic bundle welder has effectively utilized the auxiliary stand-by period of renewal part and acquisition vacuum etc. to add, improved the operating efficiency of electron beam welding device greatly, have tangible technical advantage and remarkable economic efficiency, it can be widely used in industries such as space flight, aviation, nuclear energy, weapons and instrument, automobile, technical machinery, for example material structure spare, sub-assembly and elastomeric elements such as artificial satellite parts, titanium alloy, zirconium plate, bellows, gear assembly, automobile axle shaft, electrician's contact, double metal saw belt and bimetallic material etc.
