Description
Technical field
The invention belongs to optical glass forming technical field, more particularly to a kind of small billot shaped device of optical glass.
Background technology
Optical glass product is the main material for making optical lens, optical instrument.Glass manufacturers first draw glass
Plate or square stock is made, plate or square stock pass through the methods of cutting, break, be electric fried and fritter are made, then are handled by pressure-type process
The suitable eyeglass of size is made, these eyeglasses are assembled into optical lens or instrument by last final-optics goods producer.Upper
State in process, have clout and loss because plate or square stock are made during fritter, utilization rate only has 75% or so, therefore finished product
The cost of eyeglass is higher.In order to increase operation rate and reduce cost, some common optical glass are improved by the way of die mould
Utilization rate, such as H-K9, F4 glass.But lanthanide optical glass viscosity is small, recrystallization temperature is high, easily occur during die mould striped and
Fold, therefore the general not direct die mould of production firm.In order to reduce cost, some glass manufacturers are by the group of the lanthanides of small viscosity
Optical glass is drawn into more than 20mm pole（Female rod）, a diameter of more than 5mm thin rod is made by secondary pull-rod, then pass through
Break and block material die mould is made, to reduce clout and the loss that cutting belt is come.The U of CN 203319847 patent disclosure one kind
Bar mould, this mould can draw 25mm-45mm pole（Female rod）.The U of notification number CN 203833818 patent is public
A kind of optical glass bar drawing machine of cloth, it is controllable in the range of 5~21mm more than 20mm female rod can be drawn into diameter
Thin bar.The advantages of this bar shaping is that cutting times are few, and clout and loss are low, and 5-21mm thin rod is broken well, change
The type part that length is applicable to different size is broken, practicality is wide.Although such a method reduces clout and the wave of edge of a knife cutting
Take, but preparation process is complicated, and pole shaping difficulty is more than plate and square stock, and yields is low, and the female rod both ends in secondary pull-rod
It can not utilize, therefore the effect that this pull-rod technology reduces to cost on the whole is smaller, in addition, some optical components are in side
Shape, what pole can not be economical meets cold working requirement.
And existing optical glass strip material molding mode is that glass metal is flowed on die bottom plate at present, by end cap and
Side plate cools down glass metal and curing molding, is pulled out glass by drawing stove.In such a method, die bottom plate, side plate and plug
Setting position is fixed, and temperature is high during production, if glass-pulling speed is fast, glass metal cool time deficiency will be with mould bottom
Plate, side plate and end cap and glass metal adhesion, therefore such a method can not draw narrower billot.
