Specific embodiment
Below in conjunction with drawings and examples, the invention will be further described.
Embodiment is as shown in Figure 1.Optical element blank prefabricated rods manufacturing device provided by the invention, including molding die
2, the first drawing device 3, heating device 4, the second drawing device 6 and disconnecting device 5.Wherein, the first drawing device 3 is located at molding
The lower section of mold 2, molding die 2 have Local cooling mechanism, heating mechanism and its temperature control device, the configuration of the first drawing device 3
There are the grip device, power-equipment and speed adjustment equipment, glass metal that can securely catch glass bar hard after passing through in mold
Change the thick stick of solid circles that sizing diameter is 25 ~ 45mm.Heating device 4 is located at the lower section of the first drawing device 3, heating device 4
Heating element be circumferentially uniformly distributed, the surface of round thick stick can be enable to be cooled uniformly softening.Second drawing device 6
In the lower section of heating device 4, the second drawing device 6 is configured with the grip device, power-equipment and speed that can securely catch glass bar
Adjustment equipment is spent, speed can regulate and control, and directed movement can be done according to the speed that technique requires, for round thick stick to be drawn into directly
Diameter is the thin stick of solid circles of 4 ~ 15mm.Disconnecting device 5 is located at the lower section of the second drawing device 6, is the adjustable cutting dress of frequency
It sets, for cutting off round thin stick, round thin stick can be cut off on time, by the length of setting.
When it is implemented, the glass metal that optical glass smelting furnace 7 has been homogenized is by being manufactured directly into after the device manufacturing
Diameter is less than the compact optical element prefabricated rods of 15mm.Implementation process is specifically: glass metal passes through 1 water conservancy diversion of material leakage pipe to shaping mould
Tool 2, the design of 2 different parts of molding die have different cooling methods, and the first drawing device 3 can adjust drop-down as needed
Speed controls the unit time quantity of formed of glass metal, and such molding die 2 cooperates the first drawing device 3, according to certain technique
Regulation can manufacture glass metal at thick circular rod.Round thick stick Continued downward motion simultaneously passes through from heating device 4, heats
Device 4, which controls suitable temperature, to soften the thick stick surface of glass, and the second drawing device 6 of cooperation pulls downward on, and energy will be soft
The thick stick changed is drawn into very thin bar.
The manufacturing device of optical element prefabricated rods of the present invention is the vertical drawing mode taken when in use, and glass bar is outstanding
It is the manipulator of the first drawing device 3 to catch and stable that sky, which does not swing lean on,.First drawing device 3 and the second drawing device
6 effect is similar, but has very big difference in structure and draw rate design, and when use draws with molding die 2 cooperates first
Device 3 processed is to do at the uniform velocity drop-down movement according to molding volume, ensure that the consistency of molding volume, i.e. guarantee smelting furnace load
It is fixed；With softening plant 4 cooperate the second drawing device 6 the speed of service be not it is fixed, its drop-down speed can determine
The diameter that fixed thick stick draws and attenuates, if the temperature of softening furnace increases, the amount of glass of softening increases, and to keep the diameter of the thin stick of glass not
Become, it is necessary to drop-down speed just faster.
The manufacturing device of optical element prefabricated rods of the present invention has stringent technological procedure, molding die 2 when specifically used
Each spot temperature need strict control, guarantee that glass can pass through mold and be shaped to glass pole；The temperature of softening plant 4
It needs to control that accurate, temperature difference fluctuation is small, guarantees that first molding thick stick can be cooled uniformly softening；Two sets differ greatly
One, the second drawing device 3,6 needs to meet the different speeds of service up and down, and first drawing device 3 on actually top is first to match
Glass is shaped to circular rod by molding tool, and at this time the diameter of pole is not main Con trolling index, and the pole of pull-out is also relatively thicker,
Diameter guarantees that ovality is crucial generally in 25 ~ 45mm；Second drawing device 6 of lower part is then combined with diameter measuring device, root
It needs to adjust drop-down speed at any time according to diameter, finally produces the consistent thin stick of diameter, thin stick diameter at this moment is according to optics
What the outer diameter of element was controlled, diameter range is adjustable in 4 ~ 15mm.
Optical element prefabricated rods manufacturing device configuration provided by the invention needs some necessary ancillary equipments, including thermoelectricity
Idol, temperature control instrument, heating controller, frequency modulation motor, diameter measuring device, speed regulator etc., then cooperate the number of automation
Conversion and control instrument, auxiliary complete entire production process, in order to draw out the thin stick of glass of controlled diameter.
A kind of method for manufacturing optical element blank of the present invention includes the following steps:
1. manufacture optical element prefabricated rods: producing satisfaction manufacture optical glass by melting process from the throwing raw material of melting furnace 7 and want
The glass metal asked, glass metal flow into the molding die 2 of lower section through material leakage pipe 1, and molding die 2 is with Local cooling mechanism, heating
Mechanism and its temperature control device；The first drawing device 3 positioned at 2 lower section of molding die, speed can regulate and control, can want according to technique
The speed asked does directed movement, the thick stick of solid circles for being 25 ~ 45mm at diameter by glass-pulling；Positioned at the first drawing device 3
The heating device 4 of lower section, heating element be circumferentially uniformly distributed, the surface of round thick stick can be cooled uniformly softening；
The second drawing device 6 positioned at the lower section of heating device 4, configured with can securely catch the grip device of glass bar, power-equipment and
Speed adjustment equipment, speed can regulate and control, can according to technique require speed do directed movement, by glass-pulling at diameter be 4 ~
The round thin stick of the solid optical glass of 15mm；Disconnecting device 5 positioned at 6 lower section of the second drawing device is the adjustable cutting dress of frequency
It sets, round thin stick is cut off on time, by the length of setting；
2. the round thin stick of optical glass is examined: diameter, beauty defects, striped and the latent defect of round thin stick are examined, to circle
The classification classification of pencil rod material；
3. slice: directly becoming element blank by required thickness slice with the round thin stick of qualified glass；To beauty defects
