The molding assisted parts setting water-cooling ring 14 and positioning pin 13, glass tube is from the temperature after the extrusion of extrusion die 9, by water
Cold 14 auxiliary adjustment of ring, to reach required glass tube annealing temperature.Stack shell 5 configures detachable bottom plate 6, and bottom plate 6 is to add below
The pedestal 7 of hot stove 8, the bottom of bottom plate 6 are equipped with discharging cooling ring 14；Extrusion die 9 and silk are directed at using positioning pin 13 by bottom plate 6
Relative position between thick stick sliding block 15.
Semiconducting glass pipe is manufactured by extrusion molding apparatus shown in Fig. 2,3；Tube outer diameter is 30 millimeters, and pipe thickness is
3 millimeters.The softening point of used glass is 600 DEG C, and annealing point is 480 DEG C.Frit block is placed on 75 millimeters of internal diameter, 10 milli of wall thickness
It is heated and softened in the kuromore extrusion cylinder of rice.Extruding force < 3 ton of compression bar；The corresponding viscosity of forming temperature is 107.5Pool,
Shaping speed is 10 millis m/min.Pipe mold is squeezed out using aluminium bronze or the manufacture of nickel plating aluminum-bronze material.Extrusion die lower annular is logical
The equivalent diameter D in roadeIt is 6 millimeters；Take L/De=1.5, then the circular passage length L of extrusion die is 9 millimeters.
The extrusion equipment of this method is as shown in Figures 2 and 3.Frit block is placed in stack shell 5 and heats and softens, stack shell 5
Bottom plate 6 it is detachable.Turbine lift structure 1 is pressed by compression bar 3 and stripper plate 4 to the frit of heating；Under pressure
Frit is squeezed out by extrusion die 9, is formed tubulose, is then cooled and shaped；The glass being made of screw slider 15 and clamper 16
Pipe traction mechanism pulls downwards glass pipe.
The Extrusion Flow characteristic of frit under heat, is shown by the experimental model of Fig. 1 a, Fig. 1 b.The glass being laminated in Fig. 1 a
Glass piece (tinting on surface) is placed in similar container model, and mould tube passage is squeezed into after heating and pressure, and at this moment glass is in mould pipe
Radially (tube hub speed is maximum, and at tube wall zero) speed is for parabolic distribution for interior flowing velocity.This shows that frit is logical
When crossing extrusion die 9, characteristic is the newton-type viscous fluid of Laminar Flow, squeezes out the mean flow rate Vm of fluid in channel 12, clothes
From Hagen-Poiseuille formula: Vm=Δ pD2(wherein Δ p, η, D, L is the pressure, viscosity and channel of fluid respectively to/32 η L
Internal diameter and length).
When glass flows in the circular passage of extrusion die, D should be that (equivalent diameter De is equivalent diameter De in above formula
The external diameter minus internal diameter of circular passage).In addition, the mobile frictional resistance between glass and conduit wall, related with channel material, it is general
Frictional resistance when logical stainless steel mould high temperature between glass is greater than nickel-chrome alloy steel, and between nickel-chrome alloy steel and glass
Frictional resistance is greater than aluminium bronze；Therefore, the flow resistance of glass in the channel, in addition to glass viscosity and the geometrical factor in channel with
Outside, it is contemplated that mobile friction between glass and conduit wall, actual fluid resistance should also be in above formula plus being greater than 1
Empirical correction factor C (so that Ve=Vm/C).Then it obtains: Ve=Δ pDe 2/ C32 η L, this formula show extrusion tubulation
Relationship between each main technologic parameters.
The forming temperature and viscosity of this manufacturing method are in other than the crystallization range of glass, and frit passes through extrusion die lower part
There is viscosities il (10 more higher than general tubulation method when 126.5-8.5Pool).Which dictates that lower molding extruded velocity Ve (2-50
Milli m/min)；Thus the higher extruding force Δ p needed for, by the 1 (rated pressure of turbine lift structure for having additional deceleration case 2
3-10 tons) Lai Shixian.With this cooperation, the main geometric parameters of extrusion die 9, i.e. the length L and equivalent in lower annular channel 12
The ratio between diameter De is L/De=0.5-2.5 and the subtended angle of top horn mouth 11 is 90 ° -150 °.
From the shape of the glass tube after mold extrusion, need to continue to control；At this moment glass is in viscid elastic characteristic, In
Free wxpansion when leaving extrusion die overcomes this deformation after unloading effect by forming auxiliary device.At this moment glass is from viscous flow shape
State is transformed into rigid solid state.The forming temperature that glass is squeezed out from extrusion die 9, in the case where the temperature of cooling ring 14 is adjusted, drop
Temperature arrives the annealing temperature of glass, corresponds to glass viscosity 1013-14.5Pool.
In previous glass producing tubes by squeezing method patent, some measures were once used, for preventing the glass tube after squeezing out
Correct geometric dimension needed for deviateing.Reinforce cooling (US Patent:4,350,513) for example, squeezing out position in mold, or
Mobile adjustment die orifice position (US Patent:5,743,928) is inclined to the bending for compensating extruding pipe.However, this extrusion method
Feature is operated under higher glass viscosity and lower forming temperature, and more direct, more effective assistant formation is taken
Calibrating installation, to obtain geometric dimension accurately satisfactory glass tube.
One embodiment of the present invention has been described in detail above, but the content is only preferable implementation of the invention
Example, should not be considered as limiting the scope of the invention.It is all according to all the changes and improvements made by the present patent application range
Deng should still be within the scope of the patent of the present invention.
