Abstract
The present invention relates to an electroslag casting device for complex irregular castings. When some parts of castings deviate from central axial cords in the processing of casting complex irregular castings, (for example, when a connecting rod neck axial cord of a crank shaft deviates from a main axis neck axial cord), casting difficulty occurs. The present invention aims at solving the difficulty. The present invention is mainly composed of an upright post, an electrode holder, a transmission mechanism, two sets of driving mechanisms, etc., wherein the two sets of driving mechanisms can drive the electrode holder to do reciprocating cross movement along a horizontal plane, so a self-consumable electrode can be fed in any position outside the axial cord of a main axis neck crystallizer. Consequently, the present invention meets the requirements for casting complex irregular castings. If two devices cast alternately, big and long complex irregular castings can be cast by a short self-consumable electrode.
Description
The invention belongs to extraordinary metallurgical machinery equipment, particularly electroslag casting equipment.
At present, the type that is used for the equipment (electroslag furnace) of electroslag smelting casting both at home and abroad, the mode that feeds branch by consutrode mainly contains following three types: (1) single column single armed electroslag furnace, be characterized in simple in structure, equipment is lighter, do not exchange electrode in the fusion-casting process, the reflow process thermal regulation is stable, and spindle each several part mass ratio is more even.Shortcoming is that consutrode is longer, the smelting initial stage and latter stage the voltage difference bigger, requirement on height of workshop height, and only be suitable for producing small-sized steel ingot or founding part; (2) the two transverse arm alternative expression electroslag furnaces of twin columns, it is in fusion-casting process, and alternately feed electrode to a crystallizer carries out melting to two transverse arms, therefore can utilize the bigger steel ingot of less electrode production, and factory building height can be hanged down a bit; (above two types are disclosed in " electroslag melts great waves " Li Zhengbang, National Defense Industry Press, version in 1981, P89-97) (3) consutrode feeds electroslag furnace (Chinese patent CN86210861U) continuously, be characterized in driving the wheel turns of clamping consutrode by handwheel, worm gear, worm screw and chain, consutrode is moved up and down continuously, to realize feeding and withdrawing from of founding.
The subject matter that existing electroslag casting equipment exists is that consutrode generally can only feed along a fixing axis, can not feed the arbitrfary point outside axis.
The difficulty of bringing to founding when central axis (as: the connecting rod neck axis runout trunnion axis of bent axle) is departed from some position that the objective of the invention is to solve complicated special-shaped casts fusion-casting process medium casting.
The total technical scheme of the present invention is: utilize two cover drive mechanism electrode jaws (parts of clamping consutrode), make electrode jaw can move on the horizontal plane more arbitrarily, satisfying consutrode feeding more arbitrarily on horizontal plane, thereby satisfy the founding of complicated special-shaped casts.
Concrete technical scheme of the present invention can be to do circular arc (or circumference) motion by a drive mechanism electrode jaw on horizontal plane, and another driving mechanism then can be done straight reciprocating motion by while drive electrode clamper on horizontal plane; It also can be the straight reciprocating motion of on horizontal plane, making intersection by two driving mechanisms difference drive electrode clampers.
Whole the molten great waves equipment of electroslag can elevating mechanism be base also, under the situation that does not increase the electroslag casting equipment height, make consutrode when feeding, can also be under the control of elevating mechanism, needs rising or reduction along with the operating position, to adapt to, also reduced the height of whole electroslag casting equipment under the inoperative situation with than the consutrode of weak point, the shorter long foundry goods of electroslag casting equipment founding.
The present invention can form unit by the identical electroslag casting equipment of two covers when the large-scale complicated special-shaped casts of founding, like this, then can replace the large-scale complicated special-shaped casts of founding incessantly by the unit that the identical electroslag casting equipment of two covers is formed.
The present invention can reach following effect: (1) consutrode can feed the optional position beyond central axis, can adapt to the founding of complicated special-shaped casts; (2) the big and long foundry goods of consutrode founding that can be short, and reduced the height of whole electroslag casting equipment under the inoperative situation.
Accompanying drawing is one embodiment of the present of invention.(1) is crossbeam; (2) be guide pillar; (3) be driving motor; (4) be big transverse arm; (5) be little transverse arm; (6) be the linear reciprocation driving mechanism; (7) be electrode jaw; (8) be drive lead screw; (9) be rotating disk; (10) be rotary drive mechanism; (11) be base, this is an elevating mechanism.
The present invention will be further described by following examples.
Embodiment: accompanying drawing is depicted as one embodiment of the present of invention.By crossbeam (1), guide pillar (2), driving motor (3), big transverse arm (4), little transverse arm (5), linear reciprocation driving mechanism (6), electrode jaw (7), drive lead screw (8), rotating disk (9), rotary drive mechanism (10), base is that elevating mechanism (11) etc. is formed.Guide pillar (2) is fixing by crossbeam (1) with drive lead screw (8), and be vertically mounted on the rotating disk (9), big transverse arm (10) is driven by driving motor (3) and drive lead screw (8), pump along guide pillar (2) and drive lead screw (8), consutrode is by electrode jaw (7) clamping that is installed on the little transverse arm (5), drive by a straight line reciprocating drive mechanism (6), can make horizontal reciprocating movement along big transverse arm (4), also can follow big transverse arm (4) and pump, and can follow rotating disk (9) and under the driving of rotary drive mechanism (10), do rotation (circular arc) motion.
Whole the molten great waves equipment of electroslag is under the driving of elevating mechanism (11), can make vertical displacement movement, like this, under the situation that does not increase the electroslag casting equipment height, make consutrode when feeding, can also under the control of elevating mechanism (11), raise, to adapt to short consutrode, the shorter electroslag casting equipment founding needs of long foundry goods along with the rising of foundry goods founding position.
The units that use the identical electroslag casting equipment of two covers of the present invention the to form founding that hockets can reach the purpose of the complicated special-shaped casts big and long with short consutrode founding.
