Description
[technical field]
The present invention relates to the insulation, protection of melting, the metal soup of non-ferrous metal, ferrous metal and noble metal and alloy thereof, every the casting technique of slag, transmission and precisely quantitatively feeding (calling " given " or " accurately given " in the following text) and realize the device of this technology; relate in particular to high-melting-point or easily metal such as oxidation such as magnesium, aluminium, copper, tin and alloy melting thereof, metal soup insulation, protection, every slag, transmit with accurately given casting technique and realize the device of this technology, be applicable to that casting, cold chamber die casting and continuous casting continuous forging etc. need accurate given fields on.
[background technology]
Traditional casting technique is for the insulation of the fusing that realizes metal, metal soup, every slag and given, and general the operation stage by stage by several self-contained units finished, system's relative complex, cost height, and accurate quantification more be cannot say for sure to demonstrate,prove in given aspect.Use to such an extent that be quadric chain soup feeding machine tool hand the most widely, it can realize the given of accurate location; The quantitative problem of its given metal soup solves by changing not isometric spoon; This metal soup setter belongs to the motion of a plurality of frees degree; cost is higher; and belong to " open type ", promptly metal soup is to be exposed in the air, is not suitable for being applied to the technological requirement that magnesium alloy cast etc. must carry out the given field of protection against oxidation to metal soup.This " open type " given way, system thermal is scattered and disappeared big, and is not energy-conservation, to the negative effect also very big (certainly, increase outer cover and inject protective gas, can effectively realize the protection to metal soup, also can reduce scattering and disappearing of system thermal) of production scene operating mode.Another shortcoming of this given way is, when spoon directly extracts metal soup from bottom to top from the crucible of stove, floats on the slag charge on metal soup surface, can enter next process in company with metal soup, causes the dreg defect of foundry goods.Another kind of given mechanism is the given mechanism of reciprocating machine (calling " the given mechanism of piston type " in the following text) that the type die casting machine is filled in similar hot cell, is to integrate the mechanism of filling type and injection, belongs to directly given mode.Press the chamber to be provided with charging aperture, be equivalent to a kind of linker structure, cost simple in structure is low, and efficiency is all good than " open type " with operating mode.But this setter and control system do not have quantitative function, only be applicable to forming technology with the direct UNICOM of die cavity, that is to say that it only is applied to only need fill type, not need occasions such as quantitative hot chamber diecasting, low pressure casting, quantitatively give the conventional cast of soup also inapplicable needs.And because the pressure chamber and the piston of " the given mechanism of piston type " place among the metal soup, the extrusion process that needs high injection to fill type pressure for this class of similar magnesium alloy, aluminium alloy, metal soup temperature is generally all 630-750 ℃ of scope, be used for making and press the hotwork metal material of chamber and piston all to be in annealed condition, press the intensity of chamber significantly to descend, pressure chamber and piston apparatus that common material is made are difficult to satisfy technological requirement.Certainly adopt the metal material of anti-higher temperature to do and press chamber and piston can alleviate this problem, but the cost of device will significantly rise, press the life-span of chamber and piston also not high, so industrially seldom fill type extrusion process production aluminium alloy, magnesium alloy workpiece with the hot cell.Surpass 1400 ℃ ferrous metal soup given for temperature, more high performance high-temperature alloy also can not possess to do presses chamber and the due tensile strength of piston; Nonmetal pressure chambers such as employing pottery can anti-ly surpass 1400 ℃ high temperature, but its undercapacity is only applicable to the low pressure casting class, can't reach die casting class technological requirement.
Can protect and technology that can be accurately given and device are the most difficult realizations metal soup.At present, have two under protection against oxidation, for the method for soup: the first " blanket gas pressure type ".Its method is in airtight container, with the Compressed Gas about 0.1MPa, metal soup face integral body is depressed, and it is given that metal soup is realized through passage outflow closed container, and the specified rate of metal soup is by metal bath surface sectional area and descending distance decision.The difficult point of this mode is under the hot environment to guarantee the sealing of container, system complex cost height, and precision is not high yet, and given for the small size foundry goods is difficult to realize accurately control; It two is that pump formula under the protective atmosphere is given, and this is a kind of given way of controlling flow.Its difficult point is that the metal soup position in the production process in the crucible is constantly to change, and given is again a kind of intermitten, and the flow-control difficulty is big, precision is low, is not suitable for the given of small size foundry goods equally.And these two kinds of given modes, given process all will promote metal soup earlier at every turn, because liquid level changes, the stroke of its lifting must change, and wants the accurate control of the system that realizes, realize accurate given very difficultly, commercial Application is restricted.
[goal of the invention]
The present invention will overcome the above-mentioned deficiency of prior art; a kind of collection Metal Melting is provided; the insulation of metal soup; protection; every slag; transmit with accurately given casting technique and realize the device of this technology; accomplish that its given process link is minimum; metal soup stroke is the shortest; given mechanism kinematic is the simplest; given accuracy is much higher than tradition " blanket gas pressure type " scheme; whole technical process is automatically finished; can effectively alleviate its oxidation loss; not only be applicable to high-melting-point and to have the metal soup of strong oxidation tendency accurately given relatively such as magnesium alloy; be applicable to that also other oxidation tendency is not serious; as aluminium; copper; the metal soup of tin and alloy thereof is accurately given, also is applicable to comprise the given of all refractory metals of ferrous metal.Its automaticity height, process control procedure is reliable, apparatus structure is simple, has good industrial economy.
[summary of the invention]
The present invention is achieved in that by effective heating control mode such as electric induction, realizes to the melting of metal with to the insulation of metal soup.Crucible in two kinds of stoves of smelting furnace and holding furnace, all adopt 1 to advance two Room that go out 1 (following corresponding " cup ", " the back chamber " of claiming) formula linker structure, connected entrance is lower than liquid level, floats on the slag charge above the metal soup, can be along with next chamber that flows into of metal soup, thus finish every slag automatically." cup " of smelting furnace and holding furnace all is equipped with floating drum, and " the back chamber " of smelting furnace can link to each other with " cup " of holding furnace, and the parts of given mechanism are installed in " the back chamber " of holding furnace; Stove and accessory install additional the protective cover separate air and can be in cover the injection protective gas, realize the protection against oxidation of metal soup and heat insulation to greatest extent; Adopt control automatically on the technology, setting up a liquid level with holding furnace is the constant given liquid level of metal soup, set up with metal soup and concern in the turnover of holding furnace crucible, the corresponding closed-loop control of increase and decrease balance, by what control was placed in that floating drum upper and lower displacement in smelting furnace and the holding furnace " cup " produces metal soup is accounted for the Volume Changes (calling " row's volume type " in the following text) of benefit, very simply just can realize this liquid level equilibrium, realize the control independently and accurately of the given liquid level of metal soup, and can realize simultaneously the metal soup of smelting furnace is sent to holding furnace automatically; The quality of floating drum is slightly larger than its maximum buoyancy value when being positioned over metal soup, and mechanism is the most laborsaving and energy-conservation.The floating drum of smelting furnace is single big float-type; The floating drum of holding furnace can be a single big float-type or simultaneously and two formulas of establishing a keg buoy.Big floating drum all is used for the liquid level equilibrium control of metal soup turnover crucible liquid measure when big; And moving up and down by control holding furnace keg buoy, can subdue to soup given device turnover metal soup and formed influence of disturbance that liquid level is produced in the cycle the whole system running, the level stability that makes holding furnace metal soup is in a littler fluctuation range, make system more stable, when avoiding selecting for use the high or highly sensitive tank level control system of precision, the disturbance meeting of liquid level causes big floating drum to do idle upper and lower displacement.
Accurately given for realizing, keep the constant of metal soup face, its optimum value is that the highest point of crucible discharging opening is the guiding gutter bottom of this device.
After metal soup face was constant, given employing was determined metal soup capacity (calling " positive displacement " in the following text) and direct given mode with the utensil volume, not only have very high given accuracy, and the link of given metal soup is minimum, flow process is the shortest.It is given specifically can to take vertically to place " the given mechanism of piston type " of metal soup to carry out, this given branch " top uncoupling type " and " press-down type " two kinds of implementations.The mechanism of " top uncoupling type ", the charging aperture of pressing the chamber is in the lower end, and charging aperture to the distance of given liquid level multiply by the sectional area of pressing the chamber, has determined specified rate, and that changes then can adjust specified rate; When piston returns to the lower end of pressing the chamber, metal soup through charging aperture enter press the chamber after, pressing indoor metal soup promptly is that its technology is quantitative.Piston stroking upward is to guiding gutter, by on the quantitative metal soup carried flow to thermal-insulating guiding pipe along guiding gutter, enter building mortion again, thereby finish directly given; The mechanism of " press-down type ", the charging aperture of pressing the chamber is in the upper end, a little less than metal soup face.Charging aperture has determined specified rate to the distance of descent of piston and the sectional area of pressure chamber, and that changes then can adjust specified rate; Because piston stroke is to determine earlier, quantitatively also means simultaneously and finishes.When piston returns to the upper end of pressing the chamber, metal soup through charging aperture enter press the chamber after, descent of piston is to desired location, the metal soup that is pressed down enters guiding gutter through side runner, quantitatively finishes synchronously with directly given.Because the liquid level of holding furnace metal soup is constant in a horizontal plane, the theoretical value of " press-down type " given metal soup volume equals the sectional area of piston and the product of its stroke, " top uncoupling type " then equals to press the above metal soup of indoor charging aperture volume, " top uncoupling type " do not influenced by mechanism's stroke accuracy, " top uncoupling type " given accuracy should be than " press-down type " height, and the assembly of given mechanism is also simple.The given accuracy of " top uncoupling type ", " press-down type " these two kinds of devices is than " blanket gas pressure type " height, the multiple of raising, and in theory with holding furnace liquid level sectional area and press piston cross-section long-pending ratio in chamber relevant, generally all can be greater than 10.As not considering the coefficient of friction of piston motion, then minimum given pressure theoretical value equals the stroke of piston and the product of metal soup density, during practical application, this given required pressure is about 0.01MPa---0.1MPa, thereby press the chamber can be with nonmetallic materials manufacturings such as refractory ceramicses, thereby can realize ferrous metal soup given.
We provide another kind of given scheme again, and this third implementation is the simplest, and cost is minimum.Given mechanism carries out quantitatively with not isometric spoon, because the guiding gutter of the approaching device of the metal soup face of setting, metal soup need not promote, and the spoon that need only directly overturn is poured the metal soup in the spoon into guiding gutter, thereby finishes directly given.Nonmetallic materials manufacturings such as the same available refractory ceramics of this spoon, the metal soup that can be the ferrous metal class is equally realized accurately given.
These three kinds of given implementations, the mechanism that all belongs to single degree of freedom motion just realizes directly given mode, realizes that by parallel moving mechanism the third is realized that by rotating mechanism its given stroke is the shortest for preceding two kinds, structure is the simplest.Metal soup flow to thermal-insulating guiding pipe through guiding gutter, drain on the shaped device that outreaches, thereby finish the insulation, protection of whole Metal Melting, metal soup, every slag, transmit and direct accurate given technological process.The shaped device that metal soup enters can be to carry out technological forming such as " extruding compression mod forging device ".

Accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 respectively represent a kind of given embodiment.
[specific embodiment]
Now the present invention is further illustrated in conjunction with the accompanying drawings.In the accompanying drawing; solid metal 1 is after smelting furnace 2 fusings and refining; gas shield cover 3 closes; feed protective gas 4; start float-type metal soup position balance and transmit controlling organization (calling " floating drum controlling organization " in the following text) 5; the floating drum 7 of two cell-type linker structure crucibles, 6 " cups " top that is positioned at smelting furnace 2 is descended slowly; the liquid level of the metal soup 19 in the crucible 6 progressively improves because of the intrusion of floating drum 7; the chamber connected entrance enters its " back chamber " before and after flowing through earlier; exceed the guiding gutter 8 of smelting furnace 2 and flow into " cup " of two cell-type linker structure crucibles 12 of holding furnace 9 up to liquid level; meanwhile finish first road automatically every the slag operation; holding furnace 9 and float-type metal soup position balance controlling organization thereof (calling " big floating drum controlling organization " in the following text) 10 connect electricity and started; big floating drum 11 in " the big floating drum controlling organization " 10 is together with keg buoy 20; be positioned at the crucible 12 " cup " of holding furnace 9 at first, entering of metal soup progressively occupies big floating drum 11; space between keg buoy 20 and the crucible 12 " cup ".Metal soup is with after connected entrance enters crucible 12 " back chamber ", automatically finish for the second time every slag, and then diffuse in the spoon 22 of " spoon controlling organization " 21, or enter move pressure chamber 15 in the given mechanism (calling " piston controlling organization " in the following text) 14 of vertically arranged piston by charging aperture 13.The metal soup of this moment is finished automatically every slag through No. 2 or 3 linker passages and is handled (for " spoon is given " is through 2 times, and " press-down type is given " or " top uncoupling type is given " is then through 3 times), all is enough to satisfy the requirement of production technology.Metal soup face continue to rise, and gives the Tang Kou position up to technique initialization.
Said above that this situation theory optimum value was exactly the highest point of crucible 12 discharging openings, i.e. the position of the notch of the guiding gutter 16 of holding furnace 9.On the technology low liquid level control sensor 17 and high liquid level control sensor 23 are being installed a little less than guiding gutter 16 bottom positions, the installation site of low liquid level control sensor 17 contacts is lower than the contact of high liquid level control sensor 23 slightly.Distance between two contacts is the interval of system's level fluctuation.The related each other control of two contact signals forms degenerative control system.When metal soup position arrives these two positions, earlier low liquid level control sensor 17, back high liquid level control sensor 23 sends signal, floating drum 11 in " the big floating drum controlling organization " 10 and keg buoy 20 are upwards promoted by order successively, and the contact position that assurance metal soup face finally is raised to high liquid level control sensor 23 is also settled out by the liquid level upper limit position of technique initialization simultaneously.The feeding of " floating drum controlling organization " 5, be subjected to big floating drum position sensor 27 and 24 controls of keg buoy position sensor, when " floating drum controlling organization " 5 successively received the signal of big floating drum position sensor 27 and keg buoy position sensor 24, ending floating drum 7 continues to descend, at this moment, the crucible 12 of holding furnace 9 is loading maximum metal soup of setting.Also send " big floating drum controlling organization " 10 this moments and can carry out given signal to the control system of device.When " spoon controlling organization " 21 or " piston controlling organization " 14 are received given signal, instruct its spoon 22 upsets or want upwards lifting or of piston 28 to pressing down, metal soup that spoon 22 is contained or the metal soup of pressing chamber 15 to include enter thermal-insulating guiding pipe 18 through guiding gutter 16, and on the shaped device that outreaches, finish directly given (such mechanism is called " the quantitative given mechanism of positive displacement ") of metal soup shortest route.This mechanism with single degree of freedom motion realizes given system, is that structure is the simplest, the easiest fixed system of giving of control; Because metal soup position can be set in the highest point of system's discharging opening, given institute work minimum has great advantage.
Owing to finish the used container of given technology or parts have certain volume, when it enters and leave metal soup, all can cause the liquid level of metal soup to produce fluctuation.The installation site, contact of high liquid level control sensor 23 is a little more than the contact of low liquid level control sensor 17 on the actual process, liquid level is being positioned near balance sensor 23 contacts, during level fluctuation, signal is total to be received by sensor 23 earlier, instruction keg buoy controlling organization 26 is carried out the lifting of keg buoy 20, thereby stabilizes this fluctuation.
A given process cycle is finished, the metal soup of holding furnace reduces, the liquid level of metal soup descends, high liquid level control sensor 23 signals to " keg buoy controlling organization " 26, after keg buoy 20 must make and progressively come downwards to extreme lower position, keg buoy position sensor 24 signals to " big floating drum controlling organization " 10 and " floating drum controlling organization " 5 simultaneously, preferentially allows the metal soup of smelting furnace 2 enter holding furnace 9.Floating drum 7 is descending when the extreme lower position set, and floating drum position sensor 25 sends to apparatus system can carry out new fusing working signal, and it is descending by its floating drum 11 to send signal to " big floating drum controlling organization " 10.Afterwards, the metal soup position balance of holding furnace 9 is by " big floating drum controlling organization " 10 control voluntarily.When the metal soup of holding furnace 9 constantly reduces, big floating drum 11 in " the big floating drum controlling organization " 10 goes downwards to a precalculated position, signal to " the quantitative given mechanism of positive displacement " i.e. " spoon controlling organization " 21 or " piston controlling organization " 14, make it quit work, whole technical process is all over, and waits for the beginning of new circulation.
Smelting furnace is relatively independent in the device, and a holding furnace can be connected with one or more smelting furnaces, and this one-to-many connects and can implement with parallel connection or series system; The smelting furnace holding furnace of can also getting along well is fixedly connected, adopts and directly send metal soup to go into the holding furnace mode.
For fixedly connected state, feeding intake and metal soup is done can start automatic transmission after the various melting preliminary treatment, the setting level value that transmits metal soup is identical with the given level value of holding furnace setting; When device has more than a smelting furnace, be to allow smelting furnace earlier in logic one by one to holding furnace supplying metal soup.
When device when not connecting smelting furnace, the metal soup that external melting is finished directly adds holding furnace, in logic with smelting furnace in after metal soup sent, the metal soup position balance of holding furnace 9 is by " big floating drum controlling organization " 10 control voluntarily.
Such technology and corresponding device thereof both can realize accurately given, also can improve adaptability, and accurately given as to ferrous metal, noble metal casting process reaches basic purpose such as energy-saving and cost-reducing simultaneously.
