Abstract
According to the process in accordance with the present invention, we imagine that: when the upper press mould is pressed to the pressing station where the original press mould locate, the quantitative glass melt solution necessary for fabricating glass blanks according to the pressing process is introduced in to the press mould; at the same time, also, when the press mould locates at the pressing station and after the press mould is retreated, the glass blanks are taken out from the press mould. By applications of the process, the conveyance of die equipment becomes excessive. The present invention also relates to a device suitable for applications of the present method, wherein the upper press mould (29) can circumgyrate along the side direction, around the central axis (M') of the upper press mould (29), form its starting location except where it locates at the pressing mould (22).
Description
The present invention relates to a kind of preamble corresponding to claim 1 method and for use this specially suitable, according to the device of the preamble of claim 7.Mainly use a kind of like this method for the pressed glass blank: a plurality of pressing dies are installed on the rotatable worktable at interval with an angle same in the time of in this way.After the melting liquid glass that will predesignate quantity injects those and is positioned at pressing die below the feeding device (so-called conduit), worktable turns over the angular separation of two adjacent pressing dies, and the pressing die of those new injection melting liquid glass is positioned under the top die.The patrix of determining the glass blank interior shape descends and to enter in the pressing die and the liquid glass of fusing is pressed in the profile die cavity of itself.In this process, the liquid glass of fusing injects in the adjacent pressing die that is under the conduit.(usually in its scope in several seconds) patrix withdraws from pressing die again after through the needed minimum timed interval that is shaped fully for glass blank, worktable turns over one once more corresponding to two adjacent pressing dies angle at interval, and circulation restarts.
The glass blank of having suppressed is stayed in its pressing die, by thermal radiation, at first is that the thermal conduction by pressing die is cooled to harden into till the object of dimensionally stable up to it.To being much higher than usually this necessary cooling time, this must cool off glass blank through a plurality of round-robin in pressing die the new essential press time that is shaped fully.Therefore rotary table must have a plurality of pressing dies at least, makes from the compacting station to transmit the necessary time and be equivalent at least cool off the needed time to taking out station.TK has for cooling time:
t
K＝(Z-1)t
P+Zt
T，
Wherein Z is a cycle index, t
TBe the press time, and t
PFor turning over one, rotary table is equivalent to the adjacent pressing die necessary time of angular separation at interval.Therefore the efficient of this method depends on that not only glass blank is shaped the necessary minimum time, and mainly is subjected to from the restriction of glass blank cooling up to its sclerosis required time.
Therefore a main drawback of this method is: also since application cost than higher, suppress drive unit so that the faster shaping of glass blank efficiently, the working efficiency of this method can not improve a lot.
A kind of the present art that belongs to, but the method for not publishing and try hard to improve these shortcomings for using the specially suitable device of this method.
Top die is still stayed in the pressing die later in the pressing process of itself and is kept in touch with glass blank in this method.Thereby the heat in the glass blank outside of dispersing by pressing die is got on by promptly being transmitted to top die with contacting of metal top die from the inboard of glass blank.Compare (in this way to blowing cold air in glass blank) usually top die plays and makes the inboard refrigerative positive effect of glass blank with the said the sort of method of beginning.Therefore it must rest in the pressing die and can take out and forward to the such temperature of enough firm degree of cooling off station up to being cooled in the near surface zone have at least from pressing die, and the required timed interval in general reduces significantly.Therefore after through a short period of time, just can be used for new pressing process at this method pressing die.
The shortcoming of this currently known methods is: inject independent at one for the essential quantitative melting liquid glass of glass blank, the dress filling station that is contained in compacting station front carries out, therefore on the one hand for the infrastructure cost of using the suitable device of this method owing to independent can station structure increases, transfer to the largest production efficient that can reach by this method of having suppressed station time necessary interval constraint for pressing die from the can station simultaneously.
Therefore the objective of the invention is to: develop a kind of method of getting rid of restriction glass pressing machine production efficiency, and do not need to increase significantly machine cost for this reason.Another object of the present invention is: make a kind of glass pressing unit, it is particularly suitable for using this method.
This purpose solves by method of describing in claim 1 and the glass pressing unit of describing in claim 7.
By the liquid glass of quantitative fusing was just injected the pressing die that is positioned at the compacting station before top die is pressed into, the independent can station that can abandon in method commonly used, having existed, be arranged on compacting station front on the meaning of the time sequence of method.Secondly glass blank also can just take out from its inside when also being in the compacting station when pressing die, thereby has cancelled the necessity of carrying mould.Not only reduced for the construction expenditure of using by the suitable device of method of the present invention by this measure, for example by saving up to now for the independent necessary pressing die of can station, and transfer to the compacting station from the can station by saving the pressing die of filling quantitative melting liquid glass, and in the case of necessary pressing die from presser's bit transition to taking out station, improved for usual method by the production efficiency of method of the present invention.
By in a kind of good especially structure formation of the present invention of claim 2, in order to inject the rest position of quantitative melting liquid pressing mold on glass from it, with respect to pressing direction, the side direction turn-off.Be used in compacting station perfusion melting liquid space enlargement glass, on the pressing die opening by this measure, thus on the pressing die opening, also can adopt without a doubt the large vol structure, for the necessary device of perfusion.Therefore can adopt the high and filling apparatus out of order easily, that compact is exquisite of construction expenditure.The taking-up of glass blank also can be from top realization, and top die needn't be for this reason moves the big stroke that production efficiency that a meeting may reach the present invention affects adversely for the freeboard that forms a necessity withdraws from pressing die.
Quantitative melting liquid glass can be injected pressing die later at the top die turn-off with cheap construction expenditure and special reliability, if the zero position that the charge chute that links to each other with so-called conduit can insert pressing die from top die forwards position that the opening end of a charging tube communicates with the opening of pressing die to and in the later zero position (claim 3) that rotates back into it of injection process end.
If many pressing dies that are positioned at the compacting station quantitative melting liquid glass of input and be pressed into glass blank by melting liquid glass with the top die of respective numbers before top die inserts are arranged simultaneously, can improve significantly by the production efficiency of method of the present invention according to claim 4.Here the raising of production efficiency only causes smaller construction expenditure (only be by additionally necessary top die, pressing die and the quantitative melting liquid glass is injected the expense that device constituted of pressing die).
Is the object of claim 5 by method of the present invention for a kind of concrete structure of possible application form.Here the part blank one that compacting can be assembled into a member in two pressing dies at least simultaneously two half glass workpieces for example.After the temperature that part blank surface near zone is cooled to allow to take out from pressing die at least, it will take out by means of a kind of known devices, and directly to hand to a kind of equally also be that known devices is to carry out the splicing of part blank.Because transfer process only needs the relatively shorter time, remaining in half heat in the blank can make full use of in splicing.Therefore heating energy needed again at the seam crossing of the mutual abutment surface of part blank compares with usual method and can reduce significantly.
The compacting station comprises a different set of pressing die and top die in the another kind of superior structural scheme of present method, and they are used for making glass blank to be shaped step by step.And in different pressing dies, suppress the different piece of stock simultaneously, wherein pressing die is made like this (first pressing die in a group), in previous circulation, make, can put into pressing die with (blank) to be formed back to back part blank, make in pressing process, play a part simultaneously glass blank other partially-formed and with the ligation (claim 6) of adjacent part.Yet the part blank in the pressing die of packing into be not must in this group pressing die, make can not, but can be from another kind of device, for example blow-and-blow machine.
A kind of is the object of claim 7 for using the suitable especially glass pressing unit that closes of method of the present invention.But this glass pressing unit also can be used for usual method well, because top die can turn round from its rest position side (with respect to pressing direction) that is positioned at outside the pressing die, thereby the pressing die that is in the compacting station is approaching easily, and does not need the top die of for this reason dismantling.Therefore in the case of necessary can be with comparing the operation that less processing charges carries out pressing die with common glass pressing unit.Secondly the opening of pressing die is easier to be approaching after the top die turn-off, therefore also can import quantitative melting liquid glass for the pressing die that is positioned at the compacting station with the bigger injection device of volume ratio.And also can enlarge the freeboard of pressing die top in principle by the long especially stroke of top die, but this measure consequent is a bigger plant bulk and because for realizing that long shift motion time necessary has reduced the production efficiency of device.
Preferably from conduit, import pressing die for the quantitative melting liquid glass that glass blank is essential, can be bearing in one at top die side direction turn-off fashionable dress hopper and make on the position that it is terminal with the opening of pressing die is connected (claim 8) by means of a charge chute.
Transmission that do not lag behind about one, accurate and maintenance free power from the propulsion source to the top die provides according to claim 9.If the glass pressing unit comprises a depression bar that guides movably at its axis direction, an end of depression bar and propulsion source mating reaction, its other end is handled the words particularly advantageous of top die.
The spinability of top die is structurally realized like this in first preferred constructive form of glass pressing unit: according to claim 10 cantilever that can wind the turning axle rotation that distributes perpendicular to pressing direction is housed on the frame of device, it comprises a railroad, and top die is bearing in above it by means of a planker.Its middle carriage allows top die to be pressed into pressing die to finish the pressing process of itself.
Preferably be bearing on the frame perpendicular to the traversing mechanism rotating shaft effect, length-adjustable according to claim 11 cantilever, but make top die, can be fixed on again on each desirable angle position by means of the rotation of traversing mechanism both wraparound rotating shaft by one.
The content of claim 12 is structures of a kind of preferential employing of length-adjustable traversing mechanism, it comprises one and is contained in pivoted lever on the cantilever and that guide movably at its axis direction with hinge, and it leans against on the motor-driven cam plate at the other end with it under the effect of spring force.
Depression bar was undertaken by an elbow-bar mechanism with being connected preferably of top die in this kind first preferred construction form, and it has a hinge axes (claim 13) parallel with rotating shaft.
For especially effectively with power from the former top die that passes to of power, thereby and reach high pressing force, it is favourable according to claim 14 depression bar being set like this: its central axis distributes with the central axis of top die is concentric in pressing process.
If move to its filling position at top die simultaneously from its rest position turn-off fashionable dress hopper, the quantitative melting liquid glass injects the pressing die time necessary will be reduced.The simple especially measure of a kind of that adapt therewith, structure is the content of claim 15.
If top die can seal the rotating words of direction of a side to the device frame from its zero position, near pressing die, glass blank is taken out and carry just become (claim 16) easily from its inside.
The content of claim 17 to 19 is second preferred constructive form of glass pressing unit, only needs the glass blank of very little pressure when it is particularly suitable for making.On this glass pressing unit mid frame, be provided with railroad, on it, be provided with a carriage structure that can move at pressing direction.It has one in pressing process from the outstanding support in frame closed side, top die is fixed on above it.Because the axis that support can be positioned at the carriage structure scope in the time of outside top die is in pressing die rotates back into the closed side of frame, desirable freeboard only needs short motion (stroke) on the pressing die in order to reach because the distance between rotating shaft and the top die is less, so the production efficiency of clock frequency and glass pressing unit can improve once more.
If support has the described feature of claim 18, open fully for opening one side that makes pressing die so, angle of rotation only need about 90 ° just enough.
In order to guarantee that the support that has top die can turn over desirable angle, in the structure formation of this preferred employing of glass pressing unit, be connected with benefit if having the terminal and carriage structure of the depression bar of top die according to claim 19.In any case the pressing force that is applied by top die is limited,, it gets on because must being delivered to top die by support.
Formed by moment of torsion and the adjustable motor-driven cam plate of rotating speed in a kind of preferred especially structure formation medium power source of adopting by one according to claim 20.This structure can make on the one hand top die especially fast and pin-point accuracy ground be pressed into, on the other hand the feature of this propulsion source be a need seldom upkeep cost and cheap manufacturing cost.Its noise when operation is also very little.
Because the Motor torque of driving cam dish and rotating speed are adjustable, no matter be the speed of feed that top die is pressed into pressing die, the power that still is applied in pressing process on the glass blank can be complementary with simple method and the requirement separately of being stipulated by glass blank.Wherein if necessary, can move by " pressing force figure ", that is to say that pressing force is variable in pressing process by the electric current that change is added on the motor.By selecting corresponding lobe plate shape, the velocity distribution of feeding movement can (with the method for machinery) be selected in advance in the top die decline process, and it also can be complementary with each requirement by the glass material regulation of glass blank or utilization.
Motor is a tri-phase current servomotor in by a kind of preferred constructive form of claim 21, because it can control its rotating speed and the moment of torsion that is produced by it especially delicately.If be used for the top die recoil movement according to corresponding cam plate of claim 22 utilization, top die is just return exactly from pressing die and is guaranteed so.
Test shows, if the top die back body direction that to be edge opposite with pressing direction can obtain good especially compacting result (claim 23) to the elastic element of the depression bar application of force.

The another kind of preferred structure of the top die that Fig. 8 supports pivotally.
If hereinafter read " top " or " following ", the status data when it relates to the vertical operation scheme of each represented among Fig. 2 to 8 glass pressing unit so.
Be that example has been narrated the flow process by method of the present invention with a device among Fig. 2, this device have one rectilinear, have worktable 11 and a glass pressing unit 13 that comprises eight top dies 14 of eight pressing dies 12.In order to make glass blank at first by means of a pressing die that is equipped with conduit that do not show among the figure, can rotating charge chute quantitative melting liquid glass input to be positioned at the presser position.The arrow that this injection process is represented in order to F in Fig. 1 indicates.In this process, the input of (liquid state) glass of respective numbers is led in the charge chute that each pressing die goes by the conduit order.The injection of quantitative melting liquid glass is to be undertaken by the described method of Fig. 1 in this device.Therefore if but for each charge chute and for each pressing die an own feed device is set, also can give pressing die 12 injections that are positioned on the compacting station quantitative melting liquid glass simultaneously.
Top die is pressed into pressing die 12 simultaneously after injection process end, charge chute and top die 14 go back to original position, and keep in touch with glass blank always, up to it its nearly surf zone be cooled at least have for from pressing die, take out and hand to the temperature of sufficient intensity is arranged the cooling station till.Then suppress blank and deliver to cooling station 16, the cooling station is provided with a cold air blower, perhaps can comprise the cooling frame (they do not draw in the drawings) that temperature is significantly less than glass blank and is evenly distributed, glass blank is cooled to harden fully at the cooling station together.It shifts among the work step ' at another and hands to conveying belt 15 then.
In the case of necessary can certainly, cooling frame that need not be follow-up and top die is stayed in glass blank, make glass blank in pressing die up to sclerosis fully.
Below will narrate one for using the specially suitable glass pressing unit of method of the present invention according to Fig. 2.
Except passing through additive method by pivoted lever the cam plate, for example hydraulic pressure or pneumatic piston/oil (gas) cylinder unit drive.
Shown in the charging tube 7 that is equipped with in the glass pressing unit 100 can be by a hinge 31 to be hingedly fixed in pivotally on the press drive unit protective casing 30 in same direction with top die 29.Secondly hinged by a control stick 32 and supporting arm 36 with hinge 31 charging tube 7 on the position of certain distance, the end 8 that the length of supporting arm is done so that charging tube 7 when top die 29 turn-ofves with pressing die 22 connections.
Introduce the mode of operation of this glass pressing unit below tout court.
At first promote pivoted lever 41 obliquely downwards for the represented glass pressing unit (under this state, being particularly suitable for) that is in the operation shape before the pressed glass blank in Fig. 2 by clockwise rotating cam plate 46 to the quantitative melting liquid glass of pressing die 22 cans, therefore have railroad 37 cantilevers 36 to the clockwise direction rotation, be in vertical position until railroad 37.Mentioned above, overlapped with a compacting axle P at the central axis of this position upperpush rod 27 and top die 29.The stopping operating of cam plate 46 is fixed on this position to suppress cantilever 36, and the tri-phase current driven by servomotor cam plate 25 clockwise directions rotation that pressing process is come by not drawing is equally carried out.Because the eccentric compressive bar 27 of cam plate 25 moves down and oppresses top die 29 and enters in the pressing die 22, till leaving a middle cavity suitable between the outside surface of the internal surface of pressing die 22 and top die 29 with the desirable wall thickness of glass blank.
Figure be mould bottom surface 10 with the heating of the melting liquid glass that injected and in fact can not carry out the difference of the glass blank shape that exterior cooling-basis will suppress-can cool off fast, for example use recirculated water.For a kind of possible organization plan that achieves this end is illustrated among Fig. 3, this pressing die is hole 47 of processing in the zone of its formation glass blank bottom, the water coolant nozzle 48 with the double wall return water pipe of packing in the hole.Shown in be used for making in the pressing die 29 of band neck glass cylinder, water coolant nozzle 48 is not only to pressing die 10 cooling effects rapidly in bottom, also the neck to the glass blank 9 that directly do not contact with top die 29 in pressing process plays cooling effect rapidly.Secondly can certainly pass through another where necessary, independent water cooling plant is additionally bottom the cooling die 10.
As having introduced the front, can improve by the following method especially: when glass blank only is cooled to a temperature that produces sufficient intensity in its near surface zone, just it is taken out from pressing die by the production efficiency of glass pressing machine of the present invention.But this take out in advance to make glass blank handed to follow-up cooling station 50 become essential.Represented a kind of possible structure formation among Fig. 4.
Cooling frame 50 comprises a profile part 51, and it is made like this, and glass blank is bearing in the position of requirement and makes it not produce distortion.Processed some cooling channels 52 in the profile part 51 of cooling frame 50, they are used as the import and export of cooling air, and make marks with arrow P.
In the cavity of glass blank 9, pack into the inner core part 53 of cooling frame 50, as shown in Figure 4, it closes sclerosis is taken out it later on from cooling frame taking-up element as finishing at glass blank simultaneously, the inner core part 53 of cooling frame 50 is made like this, on the one hand glass blank is bearing in to prevent the necessary position that is out of shape, on the other hand like this around glass blank, make sensitive part (being the upper limb position 54 of forming belt neck glass cylinder in the embodiment shown) directly not blow to freezing air, thus the internal stress of avoiding and perhaps can cracking.Heating unit on periphery of where necessary also can be additional by, being made in cooling frame 50 and/or the inner core part prevents that the special sensitive part of glass blank from cooling off too quickly.
As already mentioned above, the inner core part 53 of cooling frame 50 simultaneously can be as taking out element, produce one by two suction orifices that are provided with prejudicially 55 for this reason and use arrow P ' air-flow of expression, make by in the freeboard in the lower region of passage 56 between inner core part 53 and glass blank 9, the air that air inlet port 57 by being positioned at the center and the passage 58 that is attached thereto are sent into forms a negative pressure, and it can make glass blank 9 lift (in an illustrated embodiment two half modules 51,51 ' of the peripheral portion 51 of cooling frame 50 separately after).When glass blank 9 is arranged in cooling frame 50, can the cold high pressure air be sent in the cavity between glass blank 9 and the inner core part 53 by air inlet port 57 and the passage that is attached thereto 58 in the case of necessary cooling is quickened.
Device of expression among Fig. 5, two are relatively put in this device is used for processing two by glass pressing unit 100 of the present invention and is close to the half that is spliced into a member.Should be mentioned that, two glass pressing units 100 are not necessarily wanted to put relatively mutually, also can make any other spatial arrangement, if a member also can consider to allow other glass pressing unit 100 with the following method mating reaction that will narrate by a plurality of parts common the composition.
In the device shown in Fig. 5, from a conduit, come out simultaneously three strands a certain amount of 62 glass melt to be distributed to charging tube 7,7 ' by a valve (Schere) 61.Glass solution same magnitude, that distribute to charging tube 7 is sent into pressing die 29 with the top method of having narrated, in pressing die, go back to original position at top die by side direction turn-off position shown in Figure 5 and be pressed into pressing die later on, each self-forming half blank by top die.For the do not draw traversing mechanism of top die of the consideration of overall general view, the example embodiment by glass pressing unit of the present invention as shown in FIG. 2 can realize this traversing mechanism technically.
The 3rd strand of a certain amount of glass melt distributed to an injection mould 63, this injection mould the inside (for example closing and be blown into injection mould with pressurized air after) with lid 64 by from a nozzle 65, extruding glass rope of formation.This glass rope (as what also will introduce in the back) is used for two half blanks of making simultaneously 66 are spliced into a member 67.
Elaborate manufacturing processed according to Fig. 6 a to 6g now.
Each jack-up element 17 of freely forming the mould bottom surface ejects from pressing die with latter two half blank in the inherent pressing process.Then cool off formpiston 68 and sink to half blank 66 from above, the effect of cooling formpiston is equivalent to the inner core part 53 of the cooling frame of setting forth than the front.As shown in Fig. 6 c, half blank 66 is fixed on the cooling formpiston 68 by means of low pressure and hands to welding plant 69, and welding plant is arranged between the glass pressing unit 100 in by the device of Fig. 5.
Welding plant 69 comprises the mould 70 that two profiles with the half blank are complementary, and it can comprise a refrigerating unit that does not draw in the drawings and extraly.
After two half blanks 66 are upwards put into the mould 70 of welding plant 69 with its open side, their each free one where necessary by for deliver (glass blank) and open, by fixing closing up of mould 70 that a plurality of parts are formed, cool off formpiston 68 simultaneously and from half blank 66, withdraw from.Be installed in crooked, can be around the fixed mould 70 on the common swivel point 71 rotating supporting arms 72 by each opening 90 ° of reversed turning and on definite, an adjustable distance, interfixing down Face to face in opposite directions of two supporting arms 72 with them, pass through the same moved further of two half blanks by means of the glass rope of extruding by nozzle 65, and two half blanks are finished butt joint by means of the rotation of drive unit 73 perpendicular to the glass rope.
Glass rope after finishing welding process-for example by means of blast air-cut-out, and make injection mould and member separate (Fig. 6 f).
After member 67 is cooled to a suitable temperature, it clamps by means of the clamp that an embedding is arranged in the breach in the fixed mould 70, fixed mould opens, and rotates back on its position of two new half blanks of admittance, and member is then handed to for example conveying belt by means of clamp 73.
Be that another can realize the synoptic diagram by the method steps of glass pressing unit of the present invention well in Fig. 7 a to 7d.In this method, in first Fig. 7, do not draw and make a part 74 (being the bottom and the neck of band neck glass cylinder) of glass blank in the pressing die 22 ' of the glass pressing unit that comes here, simultaneously at second pressing die 22 by glass pressing unit of the present invention of working simultaneously " in another part (being cup here) of glass stock is formed in the first part.First part at the glass blank that will process in previous work tempo earlier before the quantitative glass melt 75 of input is placed on pressing die 22 for this reason " in.Pressing die 22 " to make like this, the part that first part 74 is linked to each other with the second section of glass blank puts in compacting cavity 76, makes it be melted (seeing Fig. 7 b) by quantitative liquation 75.Then be pressed into compacting cavity 76 second section of glass blank is shaped, be fixed together with first part simultaneously (seeing Fig. 7 C) by top die 29 '.At glass blank at least its surf zone is cooled to temperature that it can take out from pressing die 22 ' after, shown in Fig. 7 d, by means of a pressing die 22 with many compositions " simultaneously open jack-up element 18 ' takes out glass blank from pressing die.And where necessary it is handed to the cooling frame that does not draw among the figure.A special advantage of this method be pressing die 22 ' with pressing die 22 ' can be simultaneously with the same catheter cartridge glass solution of two different quantity where necessary, make and avoid reliably because the minute differences that may exist causes unexpected effect when glass splices.
The another kind of preferred structure formation that adopts of in Fig. 8, having represented the top die of supporting pivotally.Top die 29 when this structure formation " be contained in the end of 77 1 arms of U-shaped support, the U-shaped support is bearing on the carriage device that does not draw among the figure pivotally by the bearing 78 on the end that is arranged on another arm.For pressed glass blank 9 ' top die 29 " can be pressed into pressing die 2 by the displacement of planker on arrow R direction that comes of not drawing in the drawings " " in.In Fig. 8, can see top die 29 " and the position of support 77 after pressing process just finishes.As being seen equally by Fig. 8, charge chute 7 ' is down the side direction turn-off in working order, so that the upside of pressing die does not hinder.
In order to take out glass blank and to scratch and using quantitative glass melt to give pressing die 22 again " " charging, support 77 can be around an axle that is formed by supporting 78 in the position that the direction half-twist of arrow W dots in Fig. 8, at this position top die 29 " make pressing die 22 " " opening obstruction not fully.Simultaneously charge chute 7 ' forwards the position that dots to, its end and pressing die 22 on this position " " the opening connection.
