Specific embodiment
With reference to Fig. 1 to Fig. 5, the present invention is described further.
A kind of production method of curved panel, includes the following steps：1-1, it is fabricated to blank stick with composite fiber, and by hair
Base stick is fabricated to pole；1-2, pole is heated after bending be fabricated to curved rod；It is 1-3, multiple curved rods are glued and cure, it makes
It is made curved panel.
Step 1-1 include drawing single fiber, draw once-combined optical fiber, draw secondary composite fiber, drawing blank stick, will
Blank stick anneals and blank stick is fabricated to six steps such as pole.
It is as follows to draw single fiber step：Glass core charge bar is packed into glass cladding pipe；The high-temperature region of fiber drawing furnace is sent into, in stove
Temperature is controlled at 870-890 DEG C；It treats that Glass Transition is sagging, glass tube is evacuated, by the traction of pulling wheel, make glass skin
Expects pipe fits together with glass core charge bar, and wire-drawing temperature is controlled at 770-790 DEG C；It is cut by the chasing-attachment of wire drawing machine
Isometric single fiber, length are can be controlled between 0.8m~1.2m.
In addition, the diameter of single fiber can be controlled by adjusting the hauling speed of pulling wheel.
The step of drawing once-combined optical fiber is as follows：Multiple single fibers are arranged closely in row's stick mold, and by each list
Optical fiber ties up fastening, forms the once-combined stick that cross section is regular hexagon；Once-combined stick is suspended on wire drawing machine, is adjusted
The technological parameters such as wire drawing furnace temperature, delivery speed and drawing speed make once-combined stick by being drawn into required specification once
Composite filament, and cut into isometric once-combined optical fiber.
For wire-drawing temperature general control between 770~790 DEG C, the outer diameter of once-combined optical fiber is 2.60~2.70mm, one
The length of secondary composite fiber is 0.7m~1.0m.
Usually during once-combined optical fiber is made, veiling glare can be inserted into gap that can be between each single fiber and absorbs light
Fibre, the length that veiling glare absorbs optical fiber are identical with single fiber.Veiling glare, which absorbs optical fiber, to be drawn with veiling glare heat absorbing glass plug, is drawn
The drawing process of process parameters monochromatic light fibril processed, draw temperature are set between 750~780 DEG C.
Row's stick mold includes the upper module and lower module that mutually fasten, and middle part forms one and cuts after row's stick mold fastens
Face is the through hole of orthohexagonal.The big I of the through hole is adjusted according to production requirement and equipment processing ability.
It is similar but larger-sized using one with the step of drawing once-combined optical fiber to draw secondary composite fiber
Multiple once-combined optical fiber systems are drawn into secondary composite fiber by row's stick mold, the outer diameter of the secondary composite fiber for 1.60~
1.70mm, length are 0.7m~1.0m.
The step of drawing blank stick is as follows：Multiple secondary composite fibers are arranged in larger-sized row's stick mold
In, Formation cross-section is the multifilament stick of orthohexagonal；Multifilament stick is suspended on wire drawing machine, multifilament club head is sent to fiber drawing furnace height
Warm area makes its softening, and the temperature of high-temperature region is 870-890 DEG C at this time；Treat that the softening of multifilament club head is sagging, cool the temperature to 770~
800 DEG C, start to draw multifilament stick by pulling wheel, form fibre faceplate blank stick, blank rod outside diameter is 6~6.2mm；
After blank stick draws shaping, when being cooled in fiber drawing furnace below 40 DEG C, blank stick is taken out.
In pulling process, to ensure that the outer diameter of blank stick is larger, feeding speed should be controlled in 3~4mm/min
In the range of.
The step of blank stick is annealed is as follows：By blank stick put in the lehr, annealing furnace temperature from room temperature by 6 it is small when
Rise to 595 DEG C；And 6 hours are kept the temperature at 595 DEG C, eliminate the thermal stress of blank stick；Then from 595 DEG C of processes 60 it is small when be cooled to
30 DEG C, slow down rate of temperature fall, prevent the generation again of thermal stress；After completing annealing operation, blank stick is taken out.
The step of blank stick is fabricated to pole is as follows：With the side of coreless grinding wheel machining blanks stick, by blank rod milling
Into the pole that outer diameter is 5~5.2mm.
Step 1-2：Pole is placed in bending device, then entire mold is put into high temperature furnace, it will after being heated to 640 DEG C
Pole bending is fabricated to curved rod, and curved rod is taken out after cooling down.
In Fig. 1, the bending device includes upper die block 41 and the lower backing block positioned at 41 lower section of upper die block
42, the upper end of the lower backing block 42 is disposed with concave bending cavity 43 downwards, and the lower end of the upper die block 41 is disposed with
The protrusion to match with the bending cavity 43.Pole 5 is disposed across between the bending cavity 43 and protrusion, the upper die block
41 move down and make the pole 5 to bending 43 inner bending of cavity into curved rod.
The bending cavity 43 is angle in the section of vertical direction, and the angle is right angle or acute angle or obtuse angle, the angle
Opening upwards.The shape of the bending cavity 43 can be designed according to the actual bending angle of pole, in the present embodiment, the angle is
Right angle.
To eliminate the thermal stress in curved rod, curved rod can be made annealing treatment, annealing steps and foregoing blank stick
Annealing steps are identical.
Step 1-3：By milling and grinding machine by the side milling of a bending end of curved rod into glued plane；Each glued flat
UV glue is coated in face, and each curved rod gluing is fabricated to curved panel by each glued plane；By curved panel be placed on one it is closed
In joint sealing, with ultra violet lamp UV curing glue ten minutes.
According to actual needs, the quantity of the curved rod of mutual gluing can be adjusted.As shown in Figures 2 and 3, with four bendings
The 4th curved panel 54 that is fabricated to of sticklac conjunction, four glued bending ends do not form stauros in the 4th curved panel 54
Structure.As shown in Figure 4 and Figure 5, the second curved panel 52 being fabricated to two curved rod gluings, in second curved panel 52
Two glued bending ends are not conllinear.
After above-mentioned steps, it will usually which the end face of curved panel input terminal and output terminal is carried out fine-grinding and polishing.
Embodiments of the present invention are explained in detail above in association with attached drawing, but the invention is not restricted to above-mentioned embodiment party
Formula, can also be before present inventive concept not be departed from the knowledge possessed in the technical field those of ordinary skill
Put that various changes can be made.
