Description
Technical field
The utility model is related to a kind of cooling fins for manufacturing glass fiber bushing and the bushing of manufacture glass fibre.
Background technology
It is carried out in the bushing that the drawing of glass fibre is usually made at 1100 DEG C -1400 DEG C by platinum-rhodium alloy.It holds for a long time
It can be deformed by the platinum-rhodium alloy bushing of high temperature, platinum-rhodium alloy bushing is caused to fail.
At present, in order to radiate to platinum-rhodium alloy bushing, platinum-rhodium alloy bushing is installed on using copper sheet as cooling fin, from
And platinum-rhodium alloy bushing is prevented to be deformed at high temperature.
But copper sheet can also deform at high temperature, be unfavorable for preventing platinum-rhodium alloy bushing from deforming.
Utility model content
Copper sheet deforms at high temperature in order to prevent, and dissipating for glass fiber bushing is manufactured the utility model proposes a kind of
Backing, the cooling fin include nickel layer and layers of copper；
The nickel layer coats the layers of copper, thickness c≤3.0mm, width b≤30mm, the length a≤120mm of the layers of copper
And thickness c ' >=0.2mm of the nickel layer is so that nickel layer can bear layers of copper to nickel layer generation load at 1400 DEG C.
Layers of copper is coated, and minimum thickness is used to bear maximum at 1400 DEG C for the nickel layer of 0.2mm as shell using nickel layer
Volume is the load of 120mm × 30mm × 3.0mm copper, so that copper does not generate deformation.
Further, thickness c >=2.0mm of the layers of copper, width b >=20mm, length a >=80mm make the layers of copper heat conduction
Property is played.
The thermal conductivity of copper is related with copper consumption, in order to which the thermal conductivity of layers of copper is made to be more than the thermal conductivity of nickel layer, makes layers of copper conduct
Main heat-conducting layer, thermal conductivity are played.Therefore, layers of copper volume cannot be less than 80mm × 20 × 2.0mm.
Further, thickness c '≤0.4mm of the nickel layer with prevent the nickel layer to the layers of copper generate heat rejection.Nickel
Layer c '>0.4mm, then nickel layer to layers of copper generate heat rejection, be unfavorable for layers of copper heat dissipation.
A kind of bushing for manufacturing glass fibre, is equipped with above-mentioned cooling fin on the bushing.
The cooling fin of manufacture glass fiber bushing described in the utility model can resist 1400 DEG C of high temperature, and can
For being mounted on bushing.Compared with nickel sheet is electroplated in copper, the cooling fin of the manufacture glass fiber bushing, thickness is more
Thickness, and thickness adjustable extent is big, and performance is more excellent, and the service life is also longer.Relative to plating copper coin, the manufacture glass fibre
The cooling fin of bushing is more environmentally friendly.
Description of the drawings
Fig. 1 is a kind of cooling fin cross-section diagram for manufacture glass fiber bushing that specific embodiment of the present invention provides.
Fig. 2 is a kind of bushing for manufacture glass fibre that specific embodiment of the present invention provides.
Specific embodiment
As shown in Figure 1, a kind of cooling fin for manufacturing glass fiber bushing, the cooling fin include nickel layer 11 and layers of copper 12.
Wherein, nickel layer 11 coats layers of copper 12.
Thickness c=3.0mm, width b=30mm, the length a=120mm of layers of copper.
The thickness c=0.2mm of nickel layer.
At 1400 DEG C, the nickel layer 11 of thickness c '=0.2mm can bear the copper that volume is 120mm × 30mm × 3.0mm
Load caused by layer 12, makes layers of copper 12 not generate deformation.
Alternatively, it is also possible to which the thickness c=2.0mm of layers of copper, width b=20mm, length a=80mm is enabled to make the heat conduction of layers of copper 12
Property is played.
The thermal conductivity of layers of copper is related with copper consumption.In order to which the thermal conductivity of layers of copper is made to be more than the thermal conductivity of nickel layer, make layers of copper 12
As main heat-conducting layer.
For this purpose, layers of copper volume cannot be less than 80mm × 20mm × 2.0mm.
In addition, the thickness c ' of nickel layer>0.4mm, then nickel layer 11 is to layers of copper generation heat rejection.The nickel layer in order to prevent
11 pairs of layers of copper 12 generate heat rejection, and thickness c '≤0.4mm of nickel layer is conducive to layers of copper heat dissipation in this way.
As shown in Fig. 2, the utility model provides a kind of bushing for manufacturing glass fibre.The leakage of this manufacture glass fibre
Plate is equipped with leakage hole 22.The heat dissipation of manufacture glass fiber bushing is installed on the bushing of this manufacture glass fibre with leakage hole 22
Piece 21.After the bushing installation cooling fin 21 of this manufacture glass fibre, the bushing of this manufacture glass fibre can resist 1400
DEG C high temperature.
Cooling fin is manufactured as follows：
Using anaerobic fine copper stick and the nickel tube of more than 99.0% purity, copper rod outer diameter is smaller than nickel tube internal diameter size about
0.5mm-1mm；
The oxide layer of copper rod surface and nickel tube inner surface is gone with diluted acid and alcohol successively cleaning；
Copper rod is passed through into nickel tube, nickel tube is made to coat copper rod；
Set nickel tube copper rod is pricked into head together.
Drawing undergauge is carried out to set nickel tube copper rod in machine drawing, every time deformation about 5%-10%, total deformation reaches about
70%-80% is further continued for drawing undergauge, Zhi Daoda after 1-2 hours after every time drawing undergauge in 600 DEG C of -700 DEG C of annealing temperatures
To the thickness c=3.0mm, width b=30mm, length a=120mm of layers of copper.The thickness c=0.2mm of nickel layer.Layers of copper can also be enabled
Thickness c=2.0mm, width b=20mm, length a=80mm.
The bar of drawing in place is rolled with milling train, every time deformation about 5%-10%, total deformation reaches about
70%-80% is further continued for rolling after intermediate annealing, until the thickness and width size of needs.
The sheet material rolled is subjected to cut-to-length.
More than, the only preferable specific embodiment of the utility model, but the protection domain of utility model is not limited to
