Description
Technical field
The present invention relates to cast and a kind of liquid metal of forging industry is finished in the blank foundry technology process in same mold cavity, can be to technical process such as the selectively local or whole enforcement forgings of metal blank in the die cavity, be the quantitative pure melting of collection, pressure fills mold casting, incorporate integrated form mechanized equipment is forged in the precise temperature control casting.
Background technology
Liquid metal casting and forging technology and corresponding mechanized equipment also do not form complete supporting system on the main body equipment at present; Such as one, how on-line continuous quantitatively prepares pure metal liquid; Its two, liquid casting forge between machinery and the smelting furnace sealed continuously, quantitatively, its pure state feeding system and control system; Its three, being connected between mechanized equipment and the mold system forging function, forged in liquid casting; Its four, how the metal liquid that enters in the die cavity controls its curdled appearance, makes forging force act on the integral body of blank in the die cavity effectively in all directions; They are five years old, mode and the speed control method that machinery is finished the drift energy supply of forging function specially forged in casting, the technology that how to adapt to all many-sides of forging demand or the like of different geometries metal blank, in existing liquid metal casting forging equipment, also do not obtain paying close attention to the technology path with good supporting formula, or even describe the uniform definition that do not carry weight as yet about the feature of liquid cast forging process process.Therefore, liquid casting forging technology and such corresponding standard techniques equipment, it is not seen about above-mentioned related data in scientific and technical literatures such as the world, domestic existing patent in present industry as yet.
In present existing compression casting or even high-pressure casting technology, because the complexity of workpiece geometry, particularly have in the inside and outside low pressure or high-pressure casting technology of watering the road junction, because the process of setting of liquid metal can not solidify by desirable order, or even ingate mouth place takes the lead in solidifying, cause the process that obtains the uniformity of pressure in the blank volume in its mold cavity and constantly transmit pressure to be obstructed, thereby make the shrinkage cavity at blank thermal center place can't obtain feeding effectively, the influence that its forging force of metal stock position that has solidified applies is slackened; Therefore, in practical operation in its die cavity the technology attempt of the whole liquid forging of metal blank can't realize.
Simultaneously, in the equipment that existing extrusion casint is used, forge cylinder and the two unification of closing cylinder; How much end faces of its forging punches also are the parts of mold cavity.After its drift enters the matched moulds position and immerses in the liquid metal die cavity that remains in the counterdie cavity, the liquid metal liquid level is risen with the continuous occupancy of the technology pattern of low pressure casting, when drift stops to move down, promptly can be considered compression casting, Forging Technology termination of procedure, this moment is because the non-equilibrium of the liquid metal solidification process that otherness caused of blank geometric characteristic, still there is thermal center in the blank, then the shrinkage cavity at thermal center place will be solved effectively, and the part of blank also can't obtain the processing of Forging Technology feature.
In above analysis, when the process of film intraluminal fluid attitude metal freezing and solidify termination in an instant, if the volume of die cavity can not also can then can not finally be realized the effect of liquid its technology of casting forging to have influence on the whole blank in the film chamber completely continuously among some orientation are in the state trend that directly dwindles under the pressure all the time.Therefore can think, the design of its joint portion between the liquid forging operate portions of liquid forging equipment and mould, particularly the control to liquid metal solidification process in the die cavity is the key point that realizes the Forging Technology process; Pressure dwindles if make volume in a certain regional interface of die cavity be in continuously and its notable attribute is forging process, is vital.
In the liquid casting of present existing four-post vertical forging equipment, the general design and installation of its special-purpose forging compound cylinder pressure is aprowl on the plate, and the hydraulic coupling that plate moves down in the activity comes from the matched moulds master cylinder, therefore this kind is equipped in and starts when forging action, the reaction of bearing that forges cylinder will be offset the partial pressure of closing cylinder, not only reduced the pressure of matched moulds master cylinder and improved energy consumption, the pressure that cylinder is forged in further increase also will be subjected to restriction to a certain degree.
In the liquid casting of existing four-post vertical forging equipment, in its design to the casting process of alloy liquid, such equipment does not all design special in designated lane that reaches sealed quantitative cast manually, automatically and special-purpose accurate pure smelting equipment, but factory is according to the melting equipment of the alloy liquid of self-condition collocation that is be conventional cast industry melting and casting aluminium alloy special use smelting furnace; Therefore, in process of production except molten soup is quantitatively uncertain, being mingled with of its molten soup, air-breathing, move drippage even be dropped in the inside and outside place, road junction of watering of lower die face, not only influence blank quality, also make high-strength deformation aluminium alloy, magnesium alloy adopt present liquid cast forging process difficult.
To sum up to analysis international, domestic its technical background, can think that vertical liquid metal casting forging equipment is the accurate quantitatively melting of collection and liquid soup stock conveying, compression casting, extrusion casint, the incorporate technical equipment of temperature Control Forging; Its function design to forging process must combine with the mould design again; It must combine with the technological operation and the smelting furnace control system of liquid metal casting forging equipment the technological design how molten soup can reach sealed quantitative injection Sheng fluid cylinder manually, automatically.And how on-line continuous and precisely quantitatively provide pure metal liquid and enter the process of setting of liquid metal in the die cavity controllability, forge the controllability of cylinder pressure and speed, forge choosing of orientation and taking all factors into consideration of the technology systems such as design of casting forging mould for blank, remaining in system's design of liquid metal casting forging equipment needs further perfect place.
