<Supply step>
When manufacturing glass blocks, transfer bed 104 is made to be transferred at the supply position Pc on circulation road 102.Specifically, transfer moves
Send platform 104, so that the downstream in a pair of glass forming die（Right）The glass forming die 120 of side（Reference 120A）Stop
At the Pc of supply position.In the surface of the glass forming die 120 resting on supply position Pc, melten glass supply unit is set
The mass flowing nozzle 106a of 106 front ends.Here, the agitator tank omitting in melten glass supply unit 106 top and accompanying drawing, defecator,
Glass melting groove connects.In this manner it is possible to make the melten glass of melting, clarification, homogenization continuously to melten glass supply unit
106 supplies.From mass flowing nozzle 106a, the melten glass of clarification, homogenization is continuously flowed out with fixed speed.
In the lower section of the glass forming die 120 resting on supply position Pc, setting makes glass forming die 120 along vertical
The elevator 122 of direction movement.Elevator 122 has：By the slip axis body 120a of supporting glass shaping dies 120 lower surface from
The jack-up axis body 122a of lower section jack-up, and make the lifting motor that jack-up axis body 122a vertically lifts（Not shown）.?
When glass forming die 120 is transferred to supply position Pc, elevator 122 is risen and jack-up sliding axle by making jack-up axis body 122a
Body 120a, can make glass forming die 120 rise to mass flowing nozzle 106a approximated position.
In elevator 122, the glass forming die 120 rising to mass flowing nozzle 106a approximated position receives from outflow spray
The leading section of the melten glass stream that mouth 106a flows out, when this melten glass stream reaches prescribed volume, makes jack-up axis body
122a dramatic decrease.Thus, glass forming die 120（And slip axis body 120a）With the rate of outflow than melten glass stream faster
Speed decline, and the fused glass block by melten glass stream separation prescribed volume（Decline the process of chopping）.As to forming of glass
The method that mould 120 supplies fused glass block, is not limited only to the decline process of chopping described herein as, and also can adopt for example makes melting glass
Glass block is under Gravitative Loads from the method for mass flowing nozzle 106a drippage（The drippage process of chopping）Deng additive method.
Afterwards, transfer bed 104 is transferred predetermined distance, so that a pair of glass forming die middle and upper reaches（Left）The glass of side
Shaping dies 120（Reference 120B）Stay at the Pc of supply position.The time needed for this predetermined distance of transferring is, for example,
0.4s.Then, similarly upstream the glass forming die 120B of side supplies the fused glass block of prescribed volume.So, to
The each glass forming die 120 being transferred to the transfer bed 104 of supply position Pc successively supplies the melten glass of prescribed volume one by one
Block.

Therefore, in manufacturing process, so that fused glass block is floated from glass forming die 120 using the ejection pressure of gas, can suppress
Cob webbing caused by contacting with glass forming die 120.
<Stamping procedure>
Complete to supply fused glass block simultaneously to a pair of glass forming die 120, by mobile for transfer bed 104 to circulation road
Stamping position Pp on 102.It is, for example, 1.2s that transfer bed 104 is transplanted on, from supply position Pc, the time that stamping position Pp spent
（The glass forming die of supply position Pc is replaced with time=0.4s that next glass forming die is spent, with replacement
The transfer bed 104 that glass forming die is sent from supply position Pc reaches time=0.8s that stamping position Pp is spent）.Moving
The surface delivering to each glass forming die 120 of the transfer bed 104 of stamping position Pp is respectively provided with punching press mould 108.Respectively
Fused glass block in glass forming die 120 between glass forming die 120 and punching press are with mould 108 stamping for rule
Fixed shape.Now, because each fused glass block is different from being supplied to the time begin to pass through in glass forming die 120, because
This in order that after supply elapsed time equal, first by punching press forming of glass to downstream mould 108 of a side
Fused glass block in mould 120A carry out stamping, then by the opposing party punching press with mould 108 to upstream side
Fused glass block in glass forming die 120B carries out stamping, so that elapsed time is become with downstream glass after supply
Fused glass block in shape mould 120A is identical.So, by making stamping moment different, can with same precision to
In two glass forming dies, the fused glass block of supply shapes.
<Feeding operation>
When completing stamping to the fused glass block in a pair of glass forming die 120, by transfer bed 104 from punching press
Position Pp sends.The tunnel mobile station 104 sent from stamping position Pp being transplanted on the part covering circulation road 102 and arranging
In road shape heating furnace 110a.Glass blocks in each glass forming die 120 of transfer bed 104 are with the management of set point of temperature curve
Heating furnace 110a in slowly cool down.Afterwards, in the state of sufficiently cool in heating furnace 110a, glass blocks to be transferred to and follows
Feeding position Pt on loop 102.In feeding position Pt, the blow gas being produced using feeding unit 118, by each forming of glass
Two glass blocks in mould 120 are blown out to the glass blocks recoverer of in figure omission simultaneously.In order that the glass blocks of blowout will not
Produce damage etc. because of contacting with each other, this glass blocks is reclaimed by glass blocks recoverer.After feeding glass blocks, to heating furnace
110b transfers transfer bed 104.In heating furnace 110b, the temperature of glass forming die 120 is adjusted to suitable glass block and shapes
Temperature.So, carry out using each glass forming die 120 that fused glass block supply, fused glass block be stamping, glass successively
The cooling of glass block, glass blocks feeding.After heated stove 110b adjustment temperature, each glass forming die 120 turns again to supply work
Sequence and recycle.The glass blocks failing to make to be transferred to feeding position Pt greatly in the capacity of the glass blocks shaping are sufficiently cool
When, can first feeding downstream glass forming die 120A internal shaping glass blocks, the forming of glass of feeding upstream side more afterwards
The glass blocks of mould 120B internal shaping.In addition, in order to substantially ensure that cooling two glass blocks time, can make feeding position Pt to
Left side in Fig. 1（Further downstream side）Mobile etc..The capacity of molding glass block（Weight）Bigger, it is more difficult to blow out using blow gas,
Therefore also can replace blow gas, and utilize sucker to take out glass blocks from each glass forming die.
【The manufacture of glass optical component】
The press forming die with forming face will be imported to by the glass blocks that glass blocks forming device 1 shapes（Not shown）
Interior, heat and soften together with press forming die, carry out precision stamping shaping in the state of softening, after Precision Machining

Beyond the above-mentioned embodiment softening, also in advance glass blocks can be heated, import in shaping dies with the state softening
Row precision stamping shapes.
【The concrete sequential flow process that glass blocks manufacture】
Thought according to prior art general knowledge, stamping due to fused glass block is more to spend time taking work than supply
In sequence, therefore present embodiment, it is impossible to directly by transfer bed after completing to glass forming die 120 supply fused glass block
104 to stamping procedure transfer.But, the glass blocks forming device 1 of present embodiment passes through operation as described below, can be complete
Become to glass forming die 120 supply fused glass block simultaneously, transfer transfer bed 104 to stamping position Pp.That is, in this embodiment party
In formula, can be unrelated with the stamping required time, when substantially cancelling the wait of transfer bed 104 after supply fused glass block
Between, it is to avoid because the stamping production efficiency needing the cost time to cause declines.Further, since melten glass can not affected
Substantially ensure that the stamping necessary time on the premise of block service time, punching press therefore can be made in advance to use mould 108 and melt
Melt glass blocks Long contact time, fused glass block can be made fully to radiate.Therefore, after glass blocks are separated with mould 108 with punching press,
Can suppress to make profiled surface deform due to the internal heat of glass blocks, as a result, can be with high forming accuracy to glass
Block shapes.In addition, the glass blocks volume shaping is bigger（The time of stamping cost is more）, the improvement of production efficiency gets over
Good.
