Summary of the invention
The problem that invention will solve
; the device of patent documentation 1 can be independently and is controlled subtly the temperature treatment of chambers; can make shaping mould can not produce temperature variation along with shifting; and in addition; when the vibration when shifting makes the moulding starting material in shaping mould produce position skew; the optical element meeting uneven thickness, the shape defect that not only mold; also can apply the surface accuracy variation that inequality causes optical function face because uneven thickness causes punching press load; but according to the device of patent documentation 1, can utilize universal stage to translate into pattern smoothly and shaping mould not caused to vibration.So, the device of patent documentation 1 has in manufacture aspect the optical element of high-precision optical function face and possesses very excellent performance.
Yet, the inventor conducts in-depth research repeatedly, found that, in the device of patent documentation 1, while utilizing well heater in treatment chamber to heat shaping mould, sample bench also can be heated, but now because the thermal property of shaping mould and sample bench is different, causes producing heat exchange between the two, likely upsets the temperature treatment of shaping mould.And known, in the desired precision of optical element in recent years, become more and more stricter such in the situation that, the heat affecting of the sample bench of shaping mould supporting use causes detrimentally affect to high-precision moulding meeting.

Embodiment
Below, with reference to accompanying drawing, the preferred embodiment of the present invention is described.
Fig. 1 schematically shows the mould punch-forming device that embodiments of the present invention relate to (to be designated hereinafter simply as that " vertical view of the embodiment of shaped device "), Fig. 2 is the explanatory view corresponding to the device inside of the A-A section of Fig. 1.
The shaped device of present embodiment is for when accommodating the shaping mould M of the moulding starting material P such as glass preformed member with supporting station 3 supportings, to softening moulding starting material P carries out impact briquetting by shaping mould M is heated, obtain being thus shaped to the formed bodys such as optical element of desired shape.
For the shaping mould M using in present embodiment, as long as can be desired shape by moulding starting material P impact briquetting, its concrete formation be just not particularly limited.For example, shaping mould M also can be consisted of a cylinder mould 30 that is formed with a pair of patrix 10 of the molding surface facing with each other and counterdie 20 and constraint patrix 10 and counterdie 20 mutual alignment in the horizontal direction.By using such shaping mould M, can counterdie 20 with utilize cylinder mould 30 according to approaching with respect to counterdie 20, separated mode carries out between the patrix 10 of slide-and-guide, to moulding starting material, P carries out impact briquetting.
In addition, the shaped device of present embodiment is arranged to have respectively shaping mould M is carried out and comprises heating, punching press, cooling above treatment chambers of each two of processing; With the supporting station 3 that is supported with shaping mould M is transferred to the transfer device of chambers, one side by shifting the shaping mould M that accommodates moulding starting material P, Yi Bian implement successively heat treated, punching press processing, cooling process etc., each is processed, and can carry out impact briquetting.
Herein, the shaped device shown in Fig. 1 possesses and has chamber 1.Chamber 1 is to use stainless steel or other to have stable on heating metal to form, for example, by forming columnar shape after making upper and lower opening portion airtight, formation can make the inner airtight construction that keeps non-oxidizing gas atmosphere inert gas atmospheres such as () nitrogen.And, in this chamber 1, be provided with roughly equally spaced taking-up/insertion chamber P1 and the treatment chamber P2～P8 of alignment arrangements along Zhou Fangxiang.
In illustrated example, P1 is for taking out/insert chamber.This takes out/inserts chamber P1 with the taking-up operation of the shaping mould M after not damaging the mode of the set environment for the treatment of chamber P2～P8 and carrying out moulding and finish and accommodates for the insertion operation of the shaping mould M of the moulding starting material P of moulding again.
In addition, P2 is the first heating chamber, and P3 is the second heating chamber, and P4 is the 3rd heating chamber (or equal hot cell).These also can be referred to as heating part, and it implements heat treated to shaping mould M.Heat treated herein (is for example 10 with glass viscosity according to shaping mould M and moulding starting material P are reached being applicable to stamping forming temperature
6～10
11the temperature that dPas is corresponding) mode is carried out.P5 is punching press chamber.In the P5 of this punching press chamber, to utilizing the heat treated of heating part to reach the shaping mould M that is applicable to stamping forming temperature, the punching press that utilizes punching mechanism to apply punching press load is processed.
In addition, P6 is the first slow cooling chamber, and P7 is the second slow cooling chamber, and P8 is quenching chamber.These also can be referred to as cooling end, and it implements cooling process to the shaping mould M applying after punching press load.The quenching mechanism that utilizes cooling gas is preferably set in advance in quenching chamber P8, make shaping mould M cooling, reach and make to make temperature that the formed body after desired shape do not hinder flow of ambient air (for example, with glass viscosity 10 by moulding starting material P being carried out to impact briquetting
12the corresponding temperature of dPas is following).
In order to control independently respectively temperature to the temperature that is applicable to processing separately, and for the temperature in chambers is remained on to assigned temperature, these treatment chambers P2～P8 is separated by partition member (shutter) S1～S6.
In addition, in illustrated example, the supporting station 3 that supports and translate into pattern M is arranged on the universal stage 2 as transfer device, and described universal stage 2 is connected with the driving rotating mechanism that the direction of arrow along in Fig. 1 is rotated.Thus, from taking out/inserting, chamber P1 is inserted in device and at the shaping mould M of supporting station 3 upper supports, is transferred to successively environment and is set as all the time the treatment chamber P2～P8 under non-oxidizing gas atmosphere inert gas atmospheres such as () nitrogen under the state in accommodating moulding starting material (or formed body) P.
It should be noted that, universal stage 2 forms diameter and is less than the discoideus of chamber 1 internal diameter, according to the mode that the rotation center of this universal stage 2 is consistent with the center of chamber 1, installs, and can rotate freely with respect to chamber 1.
Universal stage 2 is equipped with in central authorities the possess indexing mechanism controlling organization (omit diagram) of (Index Machine), this universal stage 2 be take certain hour and is repeatedly rotated and stops as unit, just in time the rotation angle tolerance of intermittent rotation appointment, makes the supporting station 3 that is supported to pattern M move between the treatment chamber of adjacent setting thus.And, certain hour now, from utilizing intermittent rotation universal stage 2 to make supporting station 3 start to move to temporarily to stop and starting the time till movement next time, be the shaping cycle time.
It should be noted that, in present embodiment, illustrate the example of the shaped device of rotation transfevent, but also can according to the transfer device that shifts supporting station 3 with take linearly operating and form as the mode that main known driving mechanism is connected, to its specifically formation be not particularly limited.In addition, the configuration of taking out/inserting chamber P1, treatment chamber P2～P8 is also not limited to illustrated example, can carry out various changes according to the formation that shifts the transfer device of supporting station 3.And, the shape of the formed bodys such as optical element that maybe will obtain for the composition with moulding starting material P is processed and is carried out optimization heating, punching press, cooling each matchingly, such as also making heating chamber, is that four, punching press chamber are that two, slow cooling chamber are three etc.In order to improve the production efficiency of formed body, also can be set up in parallel heating chamber, punching press chamber, the slow cooling chamber of equal amts, executed in parallel needs the two or more impact briquettings of condition of different temperatures, different pressurized conditions simultaneously.
In illustrated example, the surrounding of the chambers of the first heating chamber P2, the second heating chamber P3, the 3rd heating chamber P4, punching press chamber P5, the first slow cooling chamber P6 and the second slow cooling chamber P7 is surrounded by housing 7, and this housing 7 is fixed in chamber 1 with not shown proper method.As shown in Figure 2, at the diapire 7a of housing 7, be formed with the mobile path of the supporting station 3 while translating into pattern M, the seam 7b extending along Zhou Fangxiang.By this seam 7b, supporting station 3 is entered in chambers.
Herein, Fig. 2 schematically shows the inside of the first heating chamber P2, but the second heating chamber P3, the 3rd heating chamber P4, the first slow cooling chamber P6, the second slow cooling chamber P7 can form the structure common with the first heating chamber P2 except design temperature difference.In addition, punching press chamber P5 can form the structure common with chambers except possessing having punching mechanism.
As shown in Figure 2, at the inner side surface of housing 7 that surrounds the surrounding for the treatment of chamber P2～P7, according to transferring path and mode toward each other in the face of shaping mould M, be provided with heating part 8.
By controlling the power of heating part 8, make the temperature for the treatment of chamber P2～P7 maintain design temperature separately, for example, at the front-end configuration thermopair of supporting station 3, its wire is guided to the turning axle of universal stage 2, to the leading section of supporting station 3, be that the temperature of the bottom of shaping mould M is measured, according to this measurement result, can be controlled at the power of the heating part 8 arranging in chambers.
In addition, the concrete formation of heating part 8 is not particularly limited, such as using, produces photothermal resistance heater etc.While adopting resistance heater as heating part 8, preferably banded resistive heating heating element is arranged on side in opposite directions according to the mode each other in roughly symmetrical with the tortuous state after several times on above-below direction of the inner side surface along housing 7.Now, the mode that preferably makes this radiant heat efficiently put on shaping mould M according to reflecting 8 radiant heat that send from heating part in housing 7 sets the tamper 9 of the inner face of covering shell 7 in advance.
In addition, in illustrated example, be supported to pattern M and to the supporting station 3 that the chambers of implementing heat treated, punching press processing, cooling process translates into pattern M, there is the rise part 3b of the hollow shape of erectting in vertical direction.Then, by the base portion 3c of the lower end side setting at this rise part 3b being embedded in to the hole 2a in the peripheral side formation of universal stage 2, supporting station 3 is arranged on universal stage 2.In addition, in the upper end side of rise part 3b, be provided with the mould support 3a that is supported to pattern M, and as shown in the figure, preferably on mould support 3a, plant and be provided with two above pins 6 that prevent that shaping mould M from toppling over.
It should be noted that, supporting station 3 also can arrange 2 above rise part 3b for a base portion 3c, the mould support 3a making in the upper end side setting of each rise part 3b is supported to pattern M, can be in the chambers of implementing heat treated, punching press processing, cooling process mobile more than 2 shaping mould M in the lump.Thus, to chambers, shift more than two shaping mould M at every turn simultaneously, can in a treatment chamber, arrange more than two shaping mould M and implement identical processing simultaneously, can improve the production efficiency of formed body.
It should be noted that, supporting station 3 shown in above-mentioned moves in the chambers of implementing heat treated, punching press processing, cooling process to support the state of shaping mould M, be heated together with shaping mould M, when shaping mould M being applied to punching press load, these supporting station 3 opposing punching presses are loaded and are supported to pattern M.Therefore, supporting station 3 is conventionally used and has the stainless steel and other metal materials that can tolerate the intensity of punching press load and thermotolerance, toughness, processibility and form.
On the other hand, because shaping mould M need to possess the characteristic such as hardness, low heat expansion property, compactness of appointment, thereby it conventionally uses and take the stupalith that superhard alloys such as the potteries such as silicon carbide, silicon nitride or wolfram varbide etc. are representative and form, but as a rule, the thermal conductivity of this stupalith is higher than stainless steel and other metal materials.
Therefore, than supporting station 3, the thermal conductivity of shaping mould M is higher, along with this shaping mould M moves in the chambers of implementing heat treated, punching press processing, cooling process, due to the variation of its thermal environment, between shaping mould M and supporting station 3, can produce heat exchange.
For example, when carrying out heat treated, the temperature of shaping mould M more easily rises, but along with the temperature of shaping mould M becomes higher than the temperature of supporting station 3, can produce the heat transfer from the high shaping mould M of temperature to the low supporting station 3 of temperature.In addition, when carrying out cooling process, than supporting station 3, shaping mould M is more easily cooling, but along with the temperature of shaping mould M becomes lower than the temperature of supporting station 3, can produce the heat transfer from the high supporting station 3 of temperature to the low shaping mould M of temperature.
When producing above-mentioned heat exchange between shaping mould M and supporting station 3, between contact counterdie 20 sides of supporting station 3 and patrix 10 sides, produce temperature head, be difficult to according to the mode that makes the temperature even variation of shaping mould M integral body heat, cooling.Particularly, when bigbore glass mirror is manufactured in moulding, the bore of the mould support 3a of shaping mould M, supporting station 3 also will increase, both contacts area increase, also easily at the face of both contacts, produce locality temperature distribution, be therefore more difficult to according to the mode that makes the temperature even variation of shaping mould M integral body heat, cooling.
And poor if shaping mould M produces said temperature, the surface accuracy of the glass mirror that impact briquetting goes out (Rotational Symmetry irregularity (ア ス), rotate asymmetric irregularity (Network セ)) is variation likely.
In addition, also should consider, for being supported to pattern M and transferring them to two of chambers with for support platform 3, due to thickness separately and shape have slight difference or the localized heat that produces along with time lapse deteriorated etc., sometimes cause its thermal property to produce uneven.So, when there is above-mentioned thermal property uneven in supporting station 3, and the heat exchange of carrying out between shaping mould M also cannot be constant, also likely shape representation well and accurately the optical element such as scale operation glass mirror aspect form and hinder.
In addition, if supporting station 3 and shaping mould M contact with each other with level and smooth face, specify punching press load to carry out after impact briquetting shaping mould M is applied, shaping mould M will be bonded on supporting station 3, and from supporting station 3, taking off shaping mould M will be more difficult.
Therefore, for present embodiment, when shaping mould M being bearing in to the mould support 3a of supporting station 3, as shown in Fig. 2 waits, on mould support 3a, dispose pedestal unit 5, across this pedestal unit 5, be supported to pattern M.Thus, can be shaping mould M be heated, be suppressed to the heat exchange between pattern M and supporting station 3 when cooling, make the heat affecting of supporting station 3 can not involve shaping mould M, and can avoid the adhesion of supporting station 3 and shaping mould M.
Herein, Fig. 3 is for representing the explanatory view of an embodiment of pedestal unit 5, and Fig. 3 (a) is the orthographic plan of pedestal unit 5, and Fig. 3 (b) is the B-B sectional view of the 3rd (a) figure.In addition, Fig. 4 is the main position amplification profile that in presentation graphs 2, long and short dash line surrounds part.
As shown in these figures, the pedestal unit 5 in present embodiment possesses: the supporting plate 51 of disc-shape; Be formed with the plate-shaped member 52 of two above hole 52a; Remain on the rolling body 53 in each hole 52a forming on plate-shaped member 52 with the mode rolling.In each hole 52a that supporting plate 51 and plate-shaped member 52 form on plate-shaped member 52, accommodate under the state of rolling body 53 by combining such as being pressed into, welding or screw togather etc.In addition, as rolling body 53, preferably use the positive pellet part that diameter is 0.5mm～10mm.It should be noted that, plate-shaped member 52 also can be described as holding plate, and hole 52a also can be described as retaining hole.
The hole 52a forming on plate-shaped member 52 connects and forms on the thickness direction of plate-shaped member 52, but in order to keep in the mode that can roll rolling body 53, makes the internal diameter of hole 52a less times greater than the diameter of rolling body 53.And this hole 52a is at the part undergauge of the face side opening of plate-shaped member 52 to the diameter (with reference to Fig. 3 (b)) that is less than rolling body 53, a part that makes held rolling body 53 is outstanding and can not depart from hole 52a from the surface of plate-shaped member 52.
Now, suitably set the shape and size of each portion, make the thickness of plate-shaped member 52 be slightly less than the diameter of rolling body 53, a part for rolling body 53 is outstanding from the surface of plate-shaped member 52 to be less than the height (being preferably the height of 0.1～2mm) of the radius of rolling body 53.
By being supported to pattern M across above-mentioned pedestal unit 5, by the outstanding rolling body 53 in the surface from plate-shaped member 52, directly with a contact, be supported to the lower surface of pattern M, with a contact shape, support in fact, can reduce its contact area thus.Thus, can be suppressed to the heat exchange between pattern M and supporting station 3, avoid the heat affecting of supporting station 3 to involve shaping mould M, and can avoid supporting station 3 and shaping mould M to produce adhesion.
It should be noted that, as rolling body 53, as mentioned above, preferably use the positive pellet part that diameter is 0.5～10mm, if but the diameter of rolling body 53 is too small, cannot fully guarantee that a part for rolling body 53, from the outstanding height in the surface of plate-shaped member 52, likely cannot effectively be suppressed to the heat exchange between pattern M and supporting station 3.On the other hand, the diameter of rolling body 53 is excessive, and pedestal unit 5 cannot have the quantity of sufficient rolling body 53, when being applied with punching press load, excessive to the load of each rolling body 53, likely makes rolling body 53 breakages.
In addition, by the mode rolling, keep rolling body 53, can suppress rolling body 53 unbalanced friction occurs, its durability period is increased, make the pedestal unit 5 can life-time service.And, 53 permissions of rolling body that keep in plate-shaped member 52 are rolled in the 52a of hole, in addition can not be freely movable, even if therefore the supporting surface of the mould support 3a of supporting station 3 with respect to the horizontal plane produces inclination etc., rolling body 53 can roll and can not be partial in specific position.Thus, can support equably all the time formed body, the attitude that is bearing in the shaping mould M on supporting station 3 can run-off the straight.
As shown in Fig. 3 (a), the hole 52a that keeps rolling body 53 in the mode that can roll preferably forms on plate-shaped member 52 and can not produce local uneven with equally spaced being arranged in roughly.The arrangement of hole 52a is not limited to illustrated being staggered, and can be also for example latticed, concentric shape, radial arrangement.
From being suppressed to the such viewpoint of heat exchange between pattern M and supporting station 3, suitably set hole 52a quantity, be the quantity of rolling body 53, if the quantity of hole 52a is extremely many, while maintaining rolling body 53 in the 52a of each hole, it is many that the quantity of the rolling body 53 of butt shaping mould M becomes, and likely makes easily generation heat exchange between shaping mould M and supporting station 3.Therefore, the quantity of hole 52a, be that the quantity of rolling body 53 is preferably considered the punching press load applying when punching press is processed and is controlled at specified quantity.
For example, when the mean load that the quantity that maximum load when punching press is processed, shaping mould M being applied is designated as the rolling body 53 of Pmax, use is designated as N, apply each rolling body 53 is designated as Pn, preferably according to the mode that meets following relational expression (1), set the quantity N of rolling body 53.

S≧Sa×2…(3)
The radius of enumerating plate-shaped member 52 is that 20mm, its surface area S are 400 π mm
2situation during as example, now, according to above-mentioned (2) formula, according to the total area Sa of hole 52a, be preferably 200 π mm
2following mode is set in the quantity of the hole 52a forming on plate-shaped member 52.
If surpass half the quantity of the surface area S of plate-shaped member 52 according to the total area Sa that makes hole 52a, form hole 52a, in the 52a of hole, hold and the quantity of the rolling body 53 of butt shaping mould M increases, between shaping mould M and supporting station 3, easily produce heat exchange, be difficult to carry out subtly the temperature treatment of shaping mould M.
