Need to prove that the material of fiber guide device can use XRD (X-ray diffraction) method or XRF (x-ray fluorescence analysis) method to differentiate.
Need to prove, be meant that at the entrance side of this said wire connecting portion 11 fiber 100 to the side that wire connecting portion 11 gets into, is the right side of figure in Fig. 1 (c).In the example shown in Fig. 1 (c), fiber 100 gets into to wire connecting portion 11 from the entrance side on right side, comes out towards the direction shown in the hollow arrow.
And shown in Fig. 1 (c), fiber 100 slides on wire connecting portion 11 and transmits at a high speed towards the direction of hollow arrow, simultaneously from oily supply hole 12 ejection oil, thereby makes oil be attached to fiber 100.
At this moment, the oil of ejection moves with fiber 100 and accumulates in oil place 13, and the oil that accumulates is attached to whole of fiber 100.
In this oiling nozzle 10, requirement not only can make oil be attached to fiber 100 well, but also can fiber 100 not caused damage, does not use thereby wearing and tearing ground does not take place for a long time.
In addition, Fig. 2 representes other examples of embodiment of the fiber guide device of this embodiment respectively, (a) is the stereogram of roll-type guide, (b) is the stereogram of rod-type guide, (c) is the stereogram of guide of traversing.
Another example of the embodiment of the fiber guide device of this embodiment shown in Fig. 2 (a) is that roll-type guide 20 uses in the fibre machinery of majority, and this roll-type guide 20 is rotated and simultaneously the guide surface of V groove shape is guided fiber 100 as wire connecting portion 11.And the rod-type guide 30 shown in Fig. 2 (b) uses in order to make fiber convergence or separation in the various places of fibre machinery, and the outer peripheral face of rod-type guide 30 is guided fiber 100 as wire connecting portion 11.And; The guide 40 that traverses shown in Fig. 2 (c) uses as follows: when fiber 100 is wound on the periphery of packaging body cylindraceous; Near the periphery that with the Cylindorical rod is the packaging body that is rotated of center; Move back and forth abreast with Cylindorical rod, and the fiber 100 of wire connecting portion 11 that will pass through the groove shape simultaneously is to packaging body guiding, to be wound into homogeneous thickness.

In addition; The fiber guide device of this embodiment uses oiling nozzle 10 shown in Figure 1 to be illustrated in above example; But be not limited thereto, also can use roll-type guide 20 shown in Figure 2, rod-type guide 30 and the guide 40 that traverses, not shown ring type guide, eyelet and volute guide etc. to be used as the fiber guide device.
Need to prove, in above-mentioned example, use the fiber guide device to be illustrated, but in this embodiment, as long as wire connecting portion 11 is made up of ceramic sintered bodies at least by the example that ceramic sintered bodies constitutes.Thereby, for example can wire connecting portion 11 be made up of ceramic sintered bodies, and other position is made up of for example metal or resin.
Next, be example with oiling nozzle 10, the manufacturing approach of the fiber guide device that is made up of ceramic sintered bodies of this embodiment is described.
For example,, this raw material and solvent and ball are put into ball mill, be crushed to the granularity of regulation and make slurry aluminium oxide, zirconia, titanium dioxide, carborundum, silicon nitride or their compound and sintering aid mixed with regulation.
In addition, contain with Al in order to form 2O 3Conversion count the above and Al below the 97.0 quality % of 92.0 quality %, with CaO convert count more than the 0.7 quality % and the Ca below the 4.0 quality %, with TiO 2Conversion counts the above and Ti below the 2.2 quality % of 0.5 quality %, with ZrO 2Above and the such sintered body of Zr below the 3.0 quality % of 1.0 quality % is counted in conversion; And with purity be more than the 99.5 quality % and average grain diameter be 0.3～1 μ m aluminium oxide, calcium oxide, titanium dioxide and yittrium oxide contain the mixed of proportional zirconia for 2mol% with regulation; This raw material and solvent and ball are put into ball mill, be crushed to the granularity of regulation and make slurry.And, also can replace the situation of adding calcium oxide and titanium dioxide and add calcium titanate (CaTiO 3), insufficient section adds calcium oxide and titanium dioxide.And, when adding silica, magnesium hydroxide and chromium oxide, for example; Using purity is that the above and average grain diameter of 99.5 quality % is that each powder weighing of 0.1～1 μ m is mixed into ormal weight; This raw material and solvent and ball are put into ball mill, be crushed to the granularity of regulation, make slurry.
Next, add adhesive, then, use spray dryer, carry out spray drying and make particle to the slurry that obtains.
Next, this particle is dropped into punching machine, exert pressure and make the formed body of regulation shape.This formed body is applied cut etc., form the oiling its shape of nozzle.Need to prove, also can utilize the injection molding method to be made into body.
And when the formed body of the oiling nozzle form that obtains for example was principal component with the aluminium oxide, as long as in atmospheric atmosphere, to make maximum temperature be 1450～1750 ℃, and to make retention time under this maximum temperature be to burn till in 1～8 hour to get final product.At this, when having added calcium oxide, firing temperature is high more, firing time is long more, and calcium oxide is just many more to the solid solution capacity of aluminium oxide, so the numerical value of kurtosis (Rku) reduces.And, through the interpolation of titanium dioxide, silica and magnesium hydroxide, and can set the maximum temperature in burning till lower, also can shorten the retention time, therefore suppress the unusual grain of the crystallization particle diameter of aluminium oxide easily and grow up.Need to prove that firing conditions such as maximum temperature, retention time change according to the kind of shape, size or the firing furnace of product, therefore as long as adjust as required.
Next, utilize tumbling mill that the surperficial integral body of the sintered body of the oiling nozzle form that obtains is carried out fine finishining and handle, can access the oiling nozzle 10 of this embodiment thus.And, as pre-treatment, also can make up bead etc.
Need to prove that known drum apparatus is used in the fine finishining that tumbling mill carries out, the input ratio of water, medium and product is formed about 1: 0.8: 0.5, add an amount of abrasive particle.The medium that uses can use the size of 6～10mm, and shape is as long as selection from spherical, triangular column, diamond shape, cylindric and oblique circular cylinder shape etc. is preferably used spherical.Through using spherical medium, and easily product is carried out a contact, control the degree of bias easily.And; The abrasive particle that uses uses the GC grain; And as long as the abrasive particle that uses first thick abrasive particle of grain size number and the second thin abrasive particle to mix for example, is 8: 2 through the blending ratio that makes first abrasive particle and second abrasive particle; And can utilize first abrasive particle that smoothing is carried out on the surface, and utilize second abrasive particle that the degree of bias is adjusted.Especially preferred, first abrasive particle uses the abrasive particle of #150～#320, and second abrasive particle uses the abrasive particle of #1200～#6000.And, utilize tumbling mill under rotating speed and processing time are respectively 50～130rpm10～50 hour, to carry out barreling, can control kurtosis thus.If in above-mentioned scope, process, then can with the degree of bias separately and the kurtosis obtained according to the surface roughness curve of wire connecting portion 11 be controlled to-2.0 or more respectively and below 3.0, reach more than 1.5 and below 4.5.
Need to prove, in fine finishining is handled, if prolong the barreling processing time, the tendency that then exists kurtosis to reduce.And, if reduce the size of medium or the grain size number of second abrasive particle, the tendency that then exists the degree of bias to increase.Need to prove, can suitably adjust the crystallization particle diameter according to firing temperature, the crystallization particle diameter increases if temperature raises then, and the crystallization particle diameter reduces if temperature reduces then.
The oiling nozzle 10 that so obtains can form more than-2.0 the degree of bias of obtaining according to the roughness curve on the surface of wire connecting portion 11 (Rsk) and below 3.0; The zone of representing by roughness curve that becomes crest of wire connecting portion 11 with become in the zone of trough; The zone that becomes trough can be enlarged, thereby the zone that fiber contacts with wire connecting portion can be reduced.Thus, compare for the situation of tabular surface, can reduce the zone that contacts with fiber,, also can reduce the chance that fiber contacts with wire connecting portion 11, thereby can suppress infringement fiber even if therefore wear and tear in the surface of wire connecting portion 11 with wire connecting portion 11.
Need to prove; Manufacturing approach with oiling nozzle 10 is the manufacturing approach that an example has been explained the fiber guide device of this embodiment; But for example under the situation of the such fiber guide device of guide 40 that traverses shown in the roll-type guide 20 shown in the construction drawing 2 (a) or Fig. 2 (c); Use with oiling nozzle 10 same manufacturing approaches get final product, for example under the situation of the such fiber guide device of the bar-shaped rod-type guide shown in the construction drawing 2 (b) 30, the following making get final product: the mixed raw material interpolation adhesive and make blank to adjusting average grain diameter; Through extruding formation method this blank is configured as the bar-shaped length that cuts into appropriateness; Afterwards, likewise burn till with oiling nozzle 10 and obtain sintered body, suitably select necessary grinding or cylinder grinding etc. again and process.
