After carrying out above-mentioned initial actuating, device 3 is in holding state, by the input of handling the specific input block (not having diagram) that is provided with on the base station 4, the shaping of beginning optical goods.

Particularly, at first supply with the shaping object that constitutes by nitre material etc., the shaping object is bearing on this downside shaping die 8b to the cavity space of the following side form main body 81b of shaping die 8.In addition, rotating disk 5 rotates a week, when forming unit 6 is sent to 4a place, the 1st station once more, because the optical goods that have been shaped are supported among this downside shaping die 8b, from this downside shaping die 8b, take out optical goods, form the above-mentioned supply operation (arrangement operation) of object thereafter again.This taking-up, arrangement operation can be automatically performed by specific device, and be also manually actuated.

As shown in figure 13, begin through the moment t1 behind the specified time, when shown in two dot chain line among Fig. 9, making upside that capacitance divider 9a is descended sealing vacuum bell jar 9, the output of well heater 83a, 83b is risen, further heated mould main body 81a, 81b in shaping.

The sealing of this vacuum bell jar 9, be after the container of said vesse opening and closing device 14 makes upside descend to capacitance divider 9a with cylinder 141 elongations, the piston rod of driving cylinder 144b by making connection mechanism 144 is retracted into, and removes that the fastening that fastens fork 144a and fasten protuberance 93 realizes.In addition, container is set at after removing and fastening the fastening of protuberance 93 with cylinder 141, shrinks and returns the starting position that is positioned at this closed position top, upside to capacitance divider 9a under its action of gravity with downside to capacitance divider 9b butt, vacuum bell jar 9 keeps closing state.

Then, the moment t2 after vacuum bell jar 9 is finished sealing, gas exhausting device 15 begin to discharge the gas in the treatment chamber 90, decompression in the treatment chamber 90.That is, after the vacuum pump effect of gas exhausting device 15, the air in the treatment chamber 90 is sucked into pipe connecting portion 154 through communicating aperture 152, gas drain passageway 151, device connection section 153, and the pressure in the treatment chamber 90 descends.

Then, at moment t3, as shown in Figure 9, the nitrogen supply unit outside scheming is supplied with nitrogen through the 2nd and the 3rd nitrogen supply- pipe 121b, 121c to treatment chamber 90.Thus, treatment chamber 90 is that non-oxygenated environment changes to nitrogen environment.Then, the discharge of gas stops the nitrogen supply (NS) of the 2nd nitrogen supply-pipe 121b among the above-mentioned the 2nd and the 3rd nitrogen supply-pipe 121b, the 121c simultaneously in moment t4 gas exhausting device 15 finishes treatment chamber 90, only continues the nitrogen supply (NS) of the 3rd nitrogen supply-pipe 121c.That is, the 3rd nitrogen supply-pipe 121c is communicated with the 3rd communicating aperture 87, and the 3rd communicating aperture 87 to treatment chamber 90 inner openings, can form non-oxygenated environment effectively around mould main body 81a, 81b on the close position of mould main body 81a, 81b, prevent the oxidation of shaping die 8.In addition, owing to only supply with nitrogen, can suppress to follow this nitrogen to supply with the reduction of treatment chamber 90 envrionment temperatures that take place, thereby use well heater 83a, 83b heated mould main body 81a, 81b effectively by the 3rd nitrogen supply-pipe 121c.

This gas exhausting device 15 finishes gases discharge operations after, the pipe that drives this gas exhausting device 15 connects the structure 155 of disembarking descends pipe connecting portion 154, and pipe connecting portion 154 is returned to the lower side and downside rotating disk main body 52 isolating starting positions.Make pipe connecting portion 154 return starting position like this, can remove the buckling state of gas exhausting device 15 and rotating disk 5, rotating disk 5 is rotated reposefully.

Thereafter, before moment t5, driving device of rotation driving 11, is that rotating disk 5 is rotated at the center with principal post 44, with the 1st station 4a conveyance to the 2 station 4b of forming unit 6 from processing base station 4.At this moment, other forming units 6 that rotating disk 5 is supported also conveyance simultaneously to neighbor station 4a～4d.

Crossing this moment t5, the moment that rotating disk 5 rotates behind 90 degree stops its rotation.Thus, when being positioned at forming unit 6 conveyances to the 2 station 4b that handle 4a place, base station 4 the 1st station, other forming units 6 also conveyance to neighbor station 4a, 4c, 4d place.Above-mentioned forming unit 6 because its shaping die 8 internal heater 83a, 83b, even when rotating with rotating disk 5, also can heat the shaping object, so shaping die 8 can carry out the adjustment of successive temperature.

At the 2nd station 4b, as shown in figure 10, upside maintains on the lowering position capacitance divider 9a gravitate, and vacuum bell jar 9 is kept closed state, and downside shaping die 8b gravitate maintains on the lowering position simultaneously, and shaping die 8 is kept open state.

In the 2nd station 4b place retention period, 8 built-in well heater 83a, 83b heat the shaping object by shaping die at forming unit 6, are heated at least more than the specific preheating temperature T3 (for example 500 degree).The temperature of shaping object, detect indirectly by the temperature that detects shaping die 8 with the built-in temperature sensor of well heater 83a, 83b, control part 100 control heater 83a, 83b maintain this detected temperatures than softening point temperature 724 degree of nitre material and also hang down on the punching press design temperature T1 (for example 700 degree) of certain temperature.Among Figure 13, because the temperature T of shaping object reaches punching press design temperature T1 at moment t6, after this moment t6, control heater 83a, 83b maintain punching press design temperature T1 with the temperature T of shaping object.

Then, by drove device of rotation driving 11 before and after the t6 constantly before moment t7, rotating disk 5 is that the center begins to rotate with principal post 44 once more, with 2nd station 4b conveyance to the 3 station 4cs of forming unit 6 from processing base station 4.In addition, a forming unit 6 is set at equal in the residence time at each 4a～4b place, station.

Crossing this moment t7, the moment that rotating disk 5 rotates behind 90 degree stops its rotation.Thus, the forming unit 6 that is positioned at the 4b place, the 2nd station that handles base station 4 is accepted heating, punching press, each processing of annealed by conveyance to the 3 station 4b at 4c place, the 3rd station.In addition,, also adjust the temperature of shaping object, can critically control the temperature of shaping object thus with well heater 83a, the 83b of shaping die 8 during the 2nd station 4b conveyance to the 3 station 4c.

In addition, the nitrogen that stops the 3rd nitrogen supply-pipe 121c at the moment t7 of rotating disk 5 rotations is supplied with, simultaneously in this rotating disk 5 back (t8 constantly) of stopping, discharge nitrogen manufacturing in the treatment chambers 90 as the vacuum environment of non-oxygenated environment or be close to the environment (constantly between t8～moment t11) of vacuum by gas exhausting device 15.Like this, form because treatment chamber 90 is independent, but when switching to this vacuum environment gas clean-up, prevent the generation of bubble in the optical goods effectively.

The discharge of 15 pairs of gases of this gas exhausting device, identical with the discharge of 15 pairs of gases of the 1st station 4a place gas exhausting device, connect the structure 155 of disembarking by pipe pipe connecting portion 154 is risen, this pipe connecting portion 154 is connected with the device connection section 153 of downside rotating disk main body 52 carries out.In addition, finishing the moment t11 that nitrogen is discharged, driving tube connects the structure 155 of disembarking and makes 154 declines of pipe connecting portion once more, make this pipe connecting portion 154 separate with the device connection section 153 of downside rotating disk main body 52, remove the buckling state of gas exhausting device 15 and rotating disk 5, make the rotating disk 5 ready rotating drive next time of carrying out thus.

Herein, carrying out the above-mentioned nitrogen particular moment t9 of (constantly between t8～moment t11) when discharging, topple over after restraining device 16 stablize the posture of rotating disk 5 by being arranged at the rotating disk of handling base station 4 tops, decompressor 13 seals the shaping die 8 of open states, makes the drawing of shaping object.

That is, with reference to Fig. 7, at first drive the advance and retreat cylinder 161 that rotating disk is toppled over restraining device 16, piston rod 161b releases from its cylinder main body 161a, and wedge shape block 162 is advanced to 51 thrusters of upside rotating disk main body.Because advance and retreat cylinder 161 is configured to its axis and departs from horizontal heeling condition slightly, follow the lower surface of the propelling wedge shape block 162 of piston rod 161b to move, with this upper surface butt to direction near upside rotating disk main body 51 (particularly being contact plate 58) upper surface.Like this, make the lower surface of wedge shape block 162 and the upper surface butt of upside rotating disk main body 51, can topple over the load that restraining device 16 supports from the below, stablize its posture even during decompressor 13 punching presses, also can suppress toppling over of rotating disk 5 by this rotating disk.

After stablizing the posture of rotating disk 5, implement punching press by decompressor 13 and handle.That is, with reference to Fig. 5, the downside shaping die 8 of the forming unit 6 of conveyance to the 3 station 4c becomes the mould relative up and down state of cylinder 131 with decompressor 13.Set out by this state, mould extends with cylinder 131, and promptly piston rod 131b advances upward from cylinder main body 131c, and the fastening protuberance 88 of downside shaping die 8b is inserted in the insertion section 132a of lifter plates 132.Under this insertion state, make a pair of driving cylinder 134c elongation of connection mechanism 134, make each fastening piece 134b to moving near direction, will fasten protuberance 88 and sandwich in the vertical recess 134a, connection mode cylinder 131 and downside shaping die 8b.

Then, set out by this connection state, further launch mode cylinder 131, downside shaping die 8b is given as security upward, as shown in figure 11, by this downside shaping die 8b is given as security to upside shaping die 8a, the shaping object that in (t9～moment t13 constantly) downside shaping die 8b is supported between given period carries out punching press to be handled.In the present embodiment, the stamping press of this decompressor 13 switches in can be during punching press interimly, after moment t10 well heater 83a, 83b failed, detected temperatures arrived the moment t12 behind the yield point temperature T2, and stamping press P switches to the stamping press P2 that initial relatively stamping press P1 increases.Since like this with higher stamping press P2 to carrying out the punching press processing because of being lower than the shaping object that yield point temperature T2 shrinks, can prevent the generation of residual strain, form high-precision optical goods.

Then, before the moment t13 below detected temperatures arrives point of inversion temperature T 3 (for example 530 degree), open shaping die 8.Opening of this shaping die 8 carried out with the contraction of cylinder 131 and the decline of lifter plate 132 by mould.At this moment, because connection mechanism 134 is fastened on the fastening protuberance 88 of downside shaping die 8b, downside shaping die 8b is separated effectively with upside shaping die 8a.After downside shaping die 8b separated with upside shaping die 8a, downside shaping die 8b was bearing in that gravitate descends on the lifter plate 132 of decline.

In the decline process of this downside shaping die 8b, drive the connection mechanism 134 of this decompressor 13, shrink driving cylinder 134c, fastening piece 134b is separated from each other, remove the buckling state of the fastening protuberance 88 of this fastening piece 134b and downside shaping die 8 thus.Therefore, when downside shaping die 8b descended the minimum lowering position of arrival with it, downside shaping die 8b stopped, and remained on mould and continued to descend with the lifter plate on the cylinder 131 132.This mould also stops after returning the starting position of contraction with cylinder 131, removes the buckling state of decompressor 13 and rotating disk 5 thus.

In addition, with this shaping die 8 start work concurrently, the wedge shape block 162 that rotating disk is toppled over restraining device 16 is also retreated by the contraction of its advance and retreat cylinder 161, produces the gap between the upper surface of the lower surface of wedge shape block 162 and upside rotating disk main body 51.Thereby, remove the buckling state that rotating disk 5 and rotating disk are toppled over restraining device 16, rotating disk 5 can be rotated reposefully.
