Abstract
The utility model relates to a feed device for electron bombardment furnaces, which is used for fixing raw material and making the melting portion of the raw material always keep the position aligning to a crucible. The feed device for electron bombardment furnaces is composed of a material clamping rod, a clamping head, a feed lead screw transmission mechanism, a roller way for placing the raw material, a lead screw transmission mechanism for roller way swinging, etc. The raw material not only can do the movement along the shaft line direction of the feed device, and can also do the horizontal movement perpendicular to the shaft line direction of the feed device, consequently, the feed device for electron bombardment furnaces brings a series of advantages for the production of the electron bombardment furnace, such as the diameter of the raw material is enlarged, the raw material is allowed to have definite bending degree, two times or more times of smelting do not require replacing the crucible, the furnace output is enhanced, the heat energy is fully utilized, the quality of products is improved, etc.
Description
The utility model relates to the feeding device of the electron bombardment furnace that refining of metal or remelting use.
The electron bombardment furnace that is used for refining of metal or remelting is mainly used in the purification of metal, and its formation comprises electron beam gun, feeding device, crucible, furnace shell, vacuum system and power unit.The principle of work of electron bombardment furnace then is to get on raw material and the molten bath by electron beam gun emission high-velocity electron beam, makes raw materials melt splash into crucible, moves down the cast metals that forms after the melting gradually.The purposes of electron bombardment furnace feeding device is fixing raw material and make the raw materials melt position aim at crucible all the time.Present employed electron bombardment furnace, 200kw focused electron electron-beam furnace as East Germany's production, its feeding device mainly comprises the raw material that dop that material-handling rod is connected with the material-handling rod end is connected with the dop the other end, material-handling rod is connected with the nut of a cover leading screw transmission rig, material-handling rod, dop and raw material that nut promotes to be placed on the roller-way are done linear reciprocating motion, and its shortcoming also is conspicuous.First, raw material diameter or width must be less than crucible diameter, generally than the little 1/3-1/4 of crucible diameter, otherwise will have the fused raw material of considerable part can not fall in the crucible, this is unallowable, also just owing to will limit the diameter or the width of raw material, then certainly will increase the melting heat and the consequent and increase melting non-cutting time, as temperature fall time, open stove and destroy the number of times of vacuum, it is big not only to consume heat energy, also considerable influence the turnout of stove; The second, require the strictness of raw material profile, can not be crooked excessive, otherwise also might cause fused raw material not fall in the crucible; The 3rd, the crucible diameter of secondary smelting must not splash into the interior situation of crucible otherwise unallowable fused raw material can occur greater than the crucible diameter of melting once yet; The 4th, molten bath shade (electron beam beat less than position, molten bath) is big, influences quality product and outward appearance.
Main purpose of the present utility model is the feeding device in a kind of new electron bombardment furnace of design, can the melting diameter or width greater than the raw material of crucible diameter, or not strict to the raw material shape requirement, allow the raw material of certain sinuousness, improve the throughput of stove and reduce production costs.
Another purpose of the present utility model is to make newly-designed feeding device simple in structure, and behaviour does conveniently, guarantees the inner quality and the outward appearance of product, improves yield rate.
The feeding device of the said electron bombardment furnace of the utility model comprises material-handling rod (1), the dop (2) that is connected with material-handling rod (1) front end, place material-handling rod, the roller-way (3) of dop and raw material (15), drive material folding, dop and raw material are done the straight-line lead-screw drive mechanism (4) that is installed in the furnace shell, roller-way is placed on the roller bed frame (5), lead-screw drive mechanism (6) is equipped with along the axis direction of roller-way roller in roller bed frame (5) bottom surface, make roller bed frame (5) around a spot wobble, the travelling nut (16) of lead-screw drive mechanism (6) is installed in the roller bed frame bottom surface by pin (17), make nut (16) can do horizontally rotating with respect to the roller bed frame bottom surface, when guaranteeing roller bed frame (5) swing, leading screw and nut (16) do not produce stuck phenomenon.Roller bed frame (5) is on the base plate (7) of supporting roller bed frame, and material-handling rod (1) is done to horizontally rotate with the travelling nut part (8) of lead-screw drive mechanism (4) away from an end of raw material and is connected.This structure formation, make raw material (15) not only can do translational motion along its axis direction, but also can do tangential movement perpendicular to the raw material axis, roller-way (3) can be around its rotary pin shaft (12) swing, and drives the raw material swing.
Oscillating quantity and quickening raw material swing rate in order to strengthen the raw materials melt end can be placed on rotary pin shaft (12) end of roller bed frame (5) away from raw material, by bearing pin (12) roller bed frame and base plate are coupled together.
In order to reduce the friction between roller bed frame bottom surface and base plate (7) contact surface, roller (14) can be installed in the roller bed frame bottom surface.
In order to simplify the internal structure of an organization, guarantee that material-handling rod drives raw material and swings flexibly, with screw (9) material-handling rod and intermediate connector (10) are fixed together on away from an end of raw material at material-handling rod (1), intermediate connector (10) is done to horizontally rotate with the transverse slat (11) of travelling nut part (8) by vertical bearing pin (13) and is connected.
The utility model has the advantages that:
(1) can the melting diameter or width greater than the raw material of crucible diameter, therefore reduced the melting heat and thereupon reduced melting non-cutting time, as temperature fall time, reduce and open the number of times that stove destroys vacuum, improved furnace output, reduce heat energy consumption;
(2) it is significantly crooked to allow the raw material profile to have, because crucible can longitudinal oscillation be aimed in bar fusion end;
(3) secondary or repeatedly during melting needn't be changed big crucible, and the characteristics that rely on raw material vertically can swing still can be carried out normal smelting work, reduce schedule of operation such as changing crucible.
(4) since raw material vertically can swing and make molten bath shade miscellaneous goods inner quality good, smooth in appearance.
