The method of the present invention can form ceramic sleeve blank with less deformation, high density and high precision, and the present invention has high forming efficiency and low cost.
Description
Technical field
Patent of the present invention is about the forming method of the joints of optical fibre with the zirconia ceramics sleeve blank.
Background technology
Fiber active linker be essential in the opticfiber communication cable, can repeat break-make and have successional passive device, be the means that realize that fast and reliable break-make is connected between optical fiber and equipment, optical fiber and instrument, optical fiber and the optical fiber.Lock pin and sleeve are the key parts of forming fiber active linker, and contact pin that zirconia ceramics is made and sleeve be owing to have characteristics such as processing back precision height, wear-resisting and life-span be long, just progressively substituted metal spare and being widely used.General extrusion moulding, injection molding and the injection mouldings etc. of adopting mold lock pin or sleeve blank, but for sleeve, these several forming methods have following shortcoming: density is lower behind the blank sintering of extrusion moulding, and Internal Hole Deformation strengthens, endoporus need be reserved the amount of finish of increasing, the tooling cost height; Injection molding, needs through long skimming processes before the blank sintering the equipment requirements height; The density of the zirconium white sleeve blank that hot die-casting molding goes out is very low, and base substrate can produce moderate finite deformation in the dewaxing process, and ceramic sleeve is low behind the sintering, deflection is big, is difficult to be processed into high-quality ceramic sleeve.
Summary of the invention
In order to overcome the shortcoming of joints of optical fibre zirconia ceramics sleeve blank moulding in the prior art, the invention provides a kind of efficient, low-cost, high-precision zirconia ceramics sleeve blank forming method.
The joints of optical fibre of the present invention forming method of zirconia ceramics sleeve blank, the cold isostatic compaction zirconia ceramics sleeve blank of employing precise pressure control comprises that concrete steps are as follows:
A is the zirconia powder mist projection granulating,
B packs zirconium white granulation powder into and has in the elastic mould that contains ceramic mold core of self sealing structure,
In the high-voltage oil cavity of c in cold isostatic press mould is carried out the precise pressure control extrusion forming,
D carries out sintering to ceramic molding, obtains ceramic sleeve sintered compact blank.
Before the zirconia ceramics powder moulding, need to handle through mist projection granulating, need the water content of strict control ceramic size before the granulation, in step a of the present invention, described zirconia powder mist projection granulating is after earlier Zirconium powder being added additives such as deionized water, binding agent, dispersion agent, through mist projection granulating, the powder that zirconium white is prepared into have fine flowability.Wherein said binding agent can be selected as polyvinyl alcohol, and described dispersion agent can be selected poly amic acid.
Specific practice is by weight percentage, behind the additives such as the deionized water 30～50% that Zirconium powder is added, binding agent 1～2%, dispersion agent 0.5～1%, is 50～100 microns spheroidal particle with the zirconia powder granulation through mist projection granulating.
Among the step b of the present invention, material with elastic mould that contains the high-precision ceramic core rod of self sealing structure is selected from latex, silicon rubber or urethane, core rod adopts the high zirconia ceramics rod of surface smoothness, the outside dimension of accurate control core rod, core rod outside dimension tolerance zone is generally less than 0.004mm.
The described extrusion forming of step c of the present invention is a precise pressure control, and described pressurization is selected interval at 200～300Mpa, after reaching required pressure, and the stability that keep-up pressure, Tao Ci contraction could be stablized like this, the precision of hole dimension control in could realizing.The present invention preferably pressurizes and selects the interval at 200～300MPa.For guaranteeing the stability of pressure, answer control pressure value fluctuation range to keep being stabilized in 5～10MPa.
In steps d of the present invention, described ceramic molding is carried out the agglomerating sintering range at 1400～1600 ℃.Behind oversintering, promptly obtain high-density, the endoporus tolerance is less than the high-accuracy ceramic sleeve sintered compact of 0.02mm.
Adopt method of the present invention, compare, following advantage is arranged with other ceramic sleeve forming method of prior art:
1. the snappiness mould adopts self sealing structure, needn't carry out secondary and seal, and has improved shaping efficiency, has reduced cost;
2. adopt the zirconia ceramics rod of high precision, high surface finish to do core rod, core rod is deviate from easily after the moulding, and the ceramic sleeve blanking inner hole that molds is smooth, endoporus dimensional precision height;
3. forming pressure height, the ceramic sleeve blank blank density height that molds, the sintering after strain is little, the ceramic density height.
Embodiment
The invention will be further described below in conjunction with specific embodiment:
Embodiment
The add-on of zirconia ceramics powder deionized water is 40%, and adds the binding agent of 1-2%, and 0.5% dispersion agent through mist projection granulating equipment, is the spheroidal particle of 50-100 micron with the zirconia powder granulation.Adopt latex elastic mould and zirconia ceramics rod to be core rod (the long 20mm of core rod, diameter is 3.200mm ± 0.002mm), zirconium white granulation powder packed into have in this elastic mould of self sealing structure, put into the high-voltage oil cavity of cold isostatic press, apply the pressure forming of 300MPa, keep-uped pressure 1 minute, after the moulding, ceramic molding is sloughed core rod, obtain sleeve blank, blank is put into crucible, sintering in high-temperature electric resistance furnace, temperature rise rate is 2 ℃/min, behind 1400～1600 ℃ of sintering, be incubated 4 hours, obtain the density height, Internal Hole Deformation is little, the ceramic sleeve blank sintered compact that dimensional precision is high.
The ceramic blank characteristic of method of the present invention and other method moulding is compared as follows, and sees Table 1.
The zirconium white sleeve blank characteristic that several forming methods of table 1 are made is (behind 1400 to 1600 ℃ of sintering) relatively
| Forming method | Density (g/cm 3) | Endoporus circularity (mm) | Endoporus tolerance of dimension (mm) |
| This patent method | 6.03～6.07 | 0.005 | 0.01 |
