The example of the embodiment of the fiber guide device of present embodiment is described below.
Fig. 1 represents that embodiment one example of the fiber guide device of present embodiment is oiling nozzle, (a)Being stereogram, is (b) cutaway view of the A-A ' line of (a), is (c) to represent fibre with cross sectionDimension 100 guides and makes the schematic diagram of the oiling nozzle of the state that oil adheres to.
The oiling nozzle 10 of the example shown in Fig. 1 will be formed at oiling spray in order to guide fiber 100The guide surface of the groove shape of mouth 10 is as wire connecting portion 11, and has: the entrance side to this wire connecting portion 11 is openedThe oily supply hole 12 of mouth; The long-pending oil place 13 that wire connecting portion 11 possesses.
In the present embodiment, fiber guide device by ceramic sintered bodies (following, sometimes referred to as sinteringBody) form, compared with the situation that is metal or resin with the material of fiber guide device, be difficult for producing frictionHeat, therefore can reduce the infringement to fiber. As pottery, preferably use for example aluminium oxide, oxidationZirconium, titanium dioxide, carborundum, silicon nitride or their compound.
It should be noted that, the material of fiber guide device can use XRD (X-ray diffraction) method orXRF (x-ray fluorescence analysis) method is differentiated.
It should be noted that, refer to that at the entrance side of this said wire connecting portion 11 fiber 100 is to wiringThe side that portion 11 enters is the right side of figure in Fig. 1 (c). In the example shown in Fig. 1 (c),Fiber 100 enters to wire connecting portion 11 from the entrance side on right side, goes out towards the direction shown in hollow arrowCome.
And as shown in Fig. 1 (c), fiber 100 slides and towards hollow arrow in wire connecting portion 11The direction of head transmits at a high speed, simultaneously from oily supply hole 12 ejection oil, thereby makes oil be attached to fiber 100.
Now, the oil of ejection moves and accumulates in oil place 13 together with fiber 100, and the oil accumulating is attachedIn whole of fiber 100.
In this oiling nozzle 10, requirement not only can make oil be attached to fiber 100 well, andAnd can also not cause damage to fiber 100, use thereby there are not for a long time wearing and tearing.
In addition, Fig. 2 represents respectively other examples of embodiment of the fiber guide device of present embodiment, (a)Being the stereogram of roll-type guide, is (b) stereogram of rod-type guide, (c) is the guide that traversesStereogram.
Another example of the embodiment of the fiber guide device of the present embodiment shown in Fig. 2 (a) is roll-typeGuide 20 uses in most fibre machineries, and this roll-type guide 20 is rotated and will simultaneouslyThe guide surface of V groove shape guides fiber 100 as wire connecting portion 11. And, shown in Fig. 2 (b)Rod-type guide 30 uses in order to make fiber assemble or separate in the various places of fibre machinery, andThe outer peripheral face of rod-type guide 30 is guided to fiber 100 as wire connecting portion 11. And, Fig. 2 (c)The shown guide 40 that traverses uses as follows: fiber 100 is being wound on to packaging body cylindraceousWhen periphery, near the periphery of the packaging body being rotated centered by Cylindorical rod, parallel with Cylindorical rodMove back and forth, and simultaneously by the fiber 100 of wire connecting portion 11 that has passed through groove shape to packaging bodyGuiding, to be wound into uniform thickness.
And the wire connecting portion 11 of above-mentioned fiber guide device is all slided with fiber 100, thereforeEspecially at the fiber that is special-shaped shape by the cross section of fiber or the fiber that contains hard particles to draw at a high speedLead under such harsh condition, even if require wire connecting portion 11 generation wearing and tearing to cause fiber 100Infringement is also few. Therefore, the fiber guide device of present embodiment is importantly made according to wire connecting portionThe degree of bias (Rsk) that 11 surperficial roughness curve is obtained is for more than-2.0 and below 3.0.
By the wire connecting portion of fiber guide device 11 is formed as to this structure, wire connecting portion 11 by slightlyThe region of what roughness curve represented become crest and becoming in the region of trough, can make to become troughRegion broadens, and can reduce the region that fiber contacts with wire connecting portion. Thus, even if 11 of wire connecting portionRaw wearing and tearing, also can suppress the infringement to fiber 100.
It should be noted that, the preferred scope of the degree of bias (Rsk) is more than 0.5 and below 2.5Scope. If this scope, can further increase the district that becomes trough being represented by roughness curveTerritory, can further reduce the region that fiber 100 contacts with wire connecting portion, even if therefore wire connecting portion 11There are wearing and tearing and also can further suppress the infringement to fiber 100.
In addition, the fiber guide device of present embodiment according to surperficial coarse the writing music of wire connecting portion 11The kurtosis (Rku) that line is obtained is preferably more than 1.5 and below 4.5.
By the wire connecting portion of fiber guide device 11 is formed as to this structure, can make to be write music by coarseThe radius of curvature of the front end of the crest that line represents is smaller. Thus, at the surface of wire connecting portion 11, fibreDimension 100 is easily slided, and can reduce the burden to fiber 100 with the friction of wire connecting portion 11, thusCan suppress the infringement to fiber.
It should be noted that, the preferred scope of kurtosis (Rku) is more than 2.8 and below 4.5.If this scope, can further reduce the curvature half of the front end of the crest being represented by roughness curveFootpath, therefore can be formed as close to carrying out a state contacting with fiber 100. Thus, Neng GoujinOne step reduces the region that contacts with wire connecting portion of fiber 100, can further reduce with wire connecting portion 11The burden of friction to fiber 100, can further suppress the infringement to fiber thus.
It should be noted that, the surperficial degree of bias (Rsk) and the kurtosis (Rku) of wire connecting portion 11 are passableMeasure based on JISB0601-2001, can use commercially available contact or contactless tableSurface roughness meter is measured.
In addition, in the fiber guide device of present embodiment, on the surface of wire connecting portion 11, with equivalentCircular diameter is counted more than 10 μ m crystalline particle at 10030 μ m2Scope in preferably exist 15 withUpper and below 60.
If the surface of wire connecting portion 11 is formed as to this structure, the crystalline particle that crystallization particle diameter is large existsThe surface of wire connecting portion 11 more exists, and therefore thermal conductivity is good. Thus, fiber 100 is in wiringThe heat sending while slip in portion 11 is difficult for accumulating in wire connecting portion and can dispels the heat, and therefore can reduceThe infringement of frictional heat to fiber.
It should be noted that, the method for counting of crystalline particles more than 10 μ m carries out as follows: use and sweepRetouch electron microscope, multiplying power is made as to 1000 times, with the mode butted line portion 11 of reflection electronic picturePhotograph taking is carried out on surface, for the observation image of 85 μ m × 118 μ m, uses image analysis software,Obtain the crystallization particle diameter in diameter of equivalent circle of each crystalline particle, to crystalline particles more than 10 μ mCount, also carry out same operation at other positions, measure and amount to 5 positions, calculate averageBe worth, can obtain thus the number of crystalline particles more than 10 μ m.
In addition, the ceramic sintered bodies of the fiber guide device of present embodiment preferably contains with Al2O3ConvertCount the above and Al below 97.0 quality % of 92.0 quality %, convert and count 0.7 quality % with CaOCa above and below 4.0 quality %, with TiO2Conversion is counted 0.5 quality % above and 2.2 quality %Following Ti, with ZrO2Zr more than 1.0 quality % are counted in conversion and below 3.0 quality %.
Owing to containing with Al2O3Al more than 92.0 quality % are counted in conversion and below 97.0 quality %,Therefore, therefore there is the longevity as fiber guide device in the high and excellent in wear resistance of the hardness of ceramic sintered bodiesLife is elongated tendency easily. And, due to contain the above and 97.0 quality % of 92.0 quality % following thisThe Al of the more high-termal conductivity of sample2O3, the heat of sending when therefore fiber 100 slides in wire connecting portion 11Amount is difficult for being accumulated in wire connecting portion and can dispels the heat, and therefore can reduce the infringement of frictional heat to fiber.
In addition, convert with CaO owing to containing that to count 0.7 quality % above and below 4.0 quality %Ca, therefore CaO (calcium oxide) solid solution is in Al2O3(aluminium oxide), thus can in the stage of sinteringIncrease the surface tension of crystal surface, and generate calcium aluminate (CaAl2O4), consequently can be byCrystallization cavetto. It should be noted that, replace CaO (calcium oxide) and use barium monoxide (BaO) orStrontium oxide strontia (SrO) also can obtain same effect.
In addition, owing to containing with TiO2More than 0.5 quality % is counted in conversion and below 2.2 quality %Ti, therefore TiO2(titanium dioxide) plays a role as sintering aid, and a part of solid solution andBe scattered in the crystalline particle of aluminium oxide, can improve thus the intensity of sintered body, suppress because of wire connecting portion 11The collision of hard particles containing with fiber 100 and splitting of producing on grain boundary or crystalline particleLine, therefore can improve mar proof.
In addition, owing to containing with ZrO2More than 1.0 quality % are counted in conversion and below 3.0 quality %Zr, therefore ZrO2(zirconia) not can with aluminium oxide generation solid solution, and be present in aluminium oxide and oxidationThe grain boundary of aluminium, the part that the grain of the crystallization of aluminium oxide is grown up is subject to zirconic restriction, oxidationThe crystallization of aluminium is carried out three-dimensional grain and is grown up. Thereby outstanding formation of crystallization of aluminium oxide, can be in dimensionHold and under the state of high abrasion resistance, reduce and the contacting of fiber 100, therefore can suppress fiber 100Infringement. And, for make zirconic crystallization be present in aluminium oxide and aluminium oxide grain boundary andBring effect as described above, preferably make the zirconic crystallization less than the average crystallite particle diameter of aluminium oxideDisperse to exist, especially preferably make zirconic crystallization be present in the triple point of each crystallization of aluminium oxidePlace.
In addition, in each average crystallite particle diameter, preferably, the average crystallite particle diameter of aluminium oxide is3 μ m are above and below 15 μ m, zirconic average crystallite particle diameter is more than 0.4 μ m and is less than1.5μm。
In addition, replace zirconia and use hafnium oxide (HfO2) or cerium oxide (CeO2) also can obtainTo same effect.
It should be noted that, use SEM, multiplying power is made as to 750~5000 times, rightMirror finish is carried out on the surface of sintered body, in the scope of the temperature of low 50~100 DEG C than firing temperature, entersGo after heat etching, carried out photograph taking in the mode of reflection electronic picture, to the position arbitrarily of photoDraw 3 straight lines, the aluminium oxide that mensuration straight line crosses and zirconic crystallization number and crystallization separately thereofTotal length, by the total length of crystallization separately divided by crystallization number separately and can try to achieve aluminium oxide and oxygenChange the average crystallite particle diameter of zirconium.
It should be noted that, embodiment one example of the fiber guide device of formation expression present embodimentThe contained aluminium oxide of the sintered body of the wire connecting portion 11 of oiling nozzle 10, calcium oxide, titanium dioxide andZirconic amount can use ICP (InductivelyCoupledPlasma) emission spectroanalysisMethod is carried out quantitative analysis, the value obtaining is all carried out to oxide and convert to measure.
In addition, the ceramic sintered bodies of the fiber guide device of present embodiment preferably contains with SiO2Meter convertsBe the above and Si below 0.50 quality % of 0.10 quality %, convert and count 0.02 quality % with MgOMg above and below 0.14 quality %.
Owing to containing with SiO2(silica) converts and counts 0.10 quality % above and 0.50 quality %Following Si, therefore forms glassy phase and acceleration of sintering at aluminium oxide and zirconic grain boundary,Under low temperature and in the short time, just can burn till, there is abnormal grain and become in the crystallization that therefore easily suppresses aluminium oxideLong situation. And, due to contain with MgO (magnesia) convert count 0.02 quality % more thanAnd the Mg below 0.14 quality %, therefore magnesia has inhibition aluminium oxide as grain growth inhibitorThe abnormal grain of the crystalline particle effect of growing up, thereby can be formed as having uniform crystalline structureSintered body. Thus, make crystallization and the fiber 100 of aluminium oxide of wire connecting portion 11 steady with constant intervalFixed contact, therefore the wearing and tearing of wire connecting portion 11 are few, easily suppress the infringement to fiber 100.
It should be noted that, silica and magnesian amount can use ICP (InductivelyCoupledPlasma) emission spectroanalysis method is carried out quantitative analysis, and the value obtaining is all carried out to oxygenCompound converts to measure.
In addition, the square mean square root roughness of the wire connecting portion 11 of the fiber guide device of present embodiment(Rq) be preferably 0.5 μ m above and below 1.3 μ m.
Due to the square mean square root roughness (Rq) of wire connecting portion 11 be the above and 1.3 μ m of 0.5 μ m withUnder, thereby the crystalline particle of aluminium oxide projection outstanding and that form uprises and disperses, therefore by wiringThe fiber 100 of portion 11 easily carries out contacting with the projection of the crystalline particle of aluminium oxide, difficult to fibreDimension 100 causes damage. And wire connecting portion 11 is for further inhibition and the institute that contacts of fiber 100The wearing and tearing that cause are below 1.0 μ m and preferably make arithmetic average roughness (Ra).
In addition, the ceramic sintered bodies of the fiber guide device of present embodiment preferably contains chromium oxide(Cr2O3)。

Therefore, be subject at fiber 100When damage, due to the identification morning of camera monitor, and can carry out in suitable period fiber guide deviceReplacing. And the color of fiber guide device needs only identity the basis corresponding to camera monitorThe color of fiber 100 is selected, and uses oxidation iron rule can obtain tea if replace chromium oxideThe fiber guide device of look, if use manganese dioxide can obtain the fiber guide device of black. NeedBright, the amount of iron oxide and manganese dioxide is preferably 0.01 with respect to the amount of aluminium oxideMore than quality % and below 10.0 quality %.
It should be noted that, the amount of chromium oxide, iron oxide and manganese dioxide can use ICP(InductivelyCoupledPlasma) emission spectroanalysis method is carried out quantitative analysis, by the value obtainingAll carrying out oxide converts to measure.
In addition, the fiber guide device of present embodiment uses the oiling shown in Fig. 1 in above exampleNozzle 10 is illustrated, but is not limited to this, also can use the roll-type guiding shown in Fig. 2Device 20, rod-type guide 30 and the guide 40 that traverses, not shown ring type guide, eyelet and snailShape guide etc. is used as fiber guide device.
It should be noted that, in above-mentioned example, use fiber guide device to be formed by ceramic sintered bodiesExample be illustrated, but in the present embodiment, as long as at least wire connecting portion 11 is by ceramic post sinteringBody forms. Thereby, for example wire connecting portion 11 can be made up of ceramic sintered bodies, and by otherPosition formed by for example metal or resin.
Next,, taking oiling nozzle 10 as example, being made up of ceramic sintered bodies of present embodiment is describedThe manufacture method of fiber guide device.
For example,, by aluminium oxide, zirconia, titanium dioxide, carborundum, silicon nitride or theirs is compoundThing and sintering aid mix with the ratio of regulation, and this raw material and solvent and ball are put into ball mill, pulverizingMake slurry to the granularity specifying.
In addition, contain with Al in order to be formed as2O3Conversion is counted 92.0 quality % above and 97.0 quality %Following Al, with CaO convert count the above and Ca below 4.0 quality % of 0.7 quality %, withTiO2Conversion counts the above and Ti below 2.2 quality % of 0.5 quality %, with ZrO2Conversion counts 1.0The such sintered body of Zr more than quality % and below 3.0 quality %, and be 99.5 quality % by purityAbove and average grain diameter be the containing of aluminium oxide, calcium oxide, titanium dioxide and yittrium oxide of 0.3~1 μ mRatio is that the zirconia of 2mol% mixes with the ratio of regulation, and this raw material and solvent and ball are put into ball millingMachine, is crushed to the granularity of regulation and makes slurry. And, also can replace and add calcium oxide and dioxyChange the situation of titanium and add calcium titanate (CaTiO3), insufficient section adds calcium oxide and titanium dioxide.For example, and in the time adding silica, magnesium hydroxide and chromium oxide,, using purity is 99.5Above and the average grain diameter of quality % is that each powder of 0.1~1 μ m weighs and is mixed into ormal weight, and this is formerMaterial and solvent and ball are put into ball mill, are crushed to the granularity of regulation, make slurry.
Next, add adhesive to the slurry obtaining, then, use spray dryer, sprayMist is dried to make particle.
Next, this particle is dropped into punching machine, exert pressure and make the shaping of regulation shapeBody. This formed body is applied to machining etc., be formed as the shape of oiling nozzle. It should be noted that,Also can utilize injection molding method to be made into body.
And, at the formed body of the oiling nozzle form obtaining during for example taking aluminium oxide as principal component, onlyWill in atmospheric atmosphere, make maximum temperature is 1450~1750 DEG C, and while making the maintenance under this maximum temperatureBetween be to burn till for 1~8 hour. At this,, in the time having added calcium oxide, firing temperature is higher,Firing time is longer, and calcium oxide is just more to the solid solution capacity of aluminium oxide, the therefore number of kurtosis (Rku)Value reduces. And, by the interpolation of titanium dioxide, silica and magnesium hydroxide, and can be by burningMaximum temperature in one-tenth is set lowlyer, also can shorten the retention time, therefore easily suppresses aluminium oxideThe abnormal grain of crystallization particle diameter grow up. It should be noted that, maximum temperature, retention time etc. is burnt till barPart changes according to the kind of the shape of product, size or firing furnace, therefore as long as carry out as requiredAdjust.
Next, utilize the surface integral of the sintered body of tumbling mill to the oiling nozzle form obtaining to carry outFine finishining processing, can obtain the oiling nozzle 10 of present embodiment thus. And, as pre-treatment,Also can combine bead etc.
It should be noted that, the fine finishining that tumbling mill carries out is used known drum apparatus, by water, JieThe input ratio of matter and product is formed as 1: 0.8: 0.5 left and right, adds appropriate abrasive particle. Jie who usesMatter can be used the size of 6~10mm, and shape is as long as from spherical, triangular prism shape, diamond shape, circleIn column and oblique circular cylinder shape etc., select, preferably use spherical. By using spherical medium, andEasily product is carried out to a contact, easily control the degree of bias. And the abrasive particle of use uses GC grain,And if the abrasive particle that uses thick the first abrasive particle of grain size number and thin the second abrasive particle to mix, exampleAs, be 8: 2 by making the blending ratio of the first abrasive particle and the second abrasive particle, and can utilize the first abrasive particleEffects on surface carries out smoothing, and utilizes the second abrasive particle to adjust the degree of bias. Especially preferred, the first millGrain uses the abrasive particle of #150~#320, and the second abrasive particle uses the abrasive particle of #1200~#6000. And,Utilize tumbling mill to carry out barreling under rotating speed and processing time are respectively 50~130rpm10~50 hour,Can control thus kurtosis. If process in above-mentioned scope, can be by according to wire connecting portion 11Surface roughness the curve degree of bias separately and the kurtosis obtained be controlled to respectively more than-2.0 and 3.0Below and 1.5 above and 4.5 below.
It should be noted that, in fine finishining is processed, if extend the barreling processing time, have kurtosisThe tendency reducing. And, if reduce the size of medium or the grain size number of the second abrasive particle, there is the degree of biasThe tendency increasing. It should be noted that, can suitably adjust crystallization particle diameter according to firing temperature, ifThe temperature crystallization particle diameter that raises increases, and reduces if temperature reduces crystallization particle diameter.
The oiling nozzle 10 so obtaining can be asked the surperficial roughness curve according to wire connecting portion 11The degree of bias (Rsk) going out is formed as more than-2.0 and below 3.0, being write music by coarse of wire connecting portion 11What line represented becomes the region of crest and becomes in the region of trough, can expand the district that becomes troughTerritory, thus the region that fiber contacts with wire connecting portion can be reduced. Thus, be smooth with wire connecting portion 11The situation of face is compared, and can reduce the region contacting with fiber, even if the therefore surface of wire connecting portion 11Wear and tear, also can reduce the chance that fiber contacts with wire connecting portion 11, thereby can suppress fibreThe infringement of dimension.
It should be noted that, as an example of the manufacture method of oiling nozzle 10 example, present embodiment has been describedThe manufacture method of fiber guide device, but for example at the roll-type guide 20 shown in construction drawing 2 (a)Or in the situation of the such fiber guide device of the guide 40 that traverses shown in Fig. 2 (c), use and noteThe manufacture method that oil burner nozzle 10 is same, for example, at the bar-shaped rod-type shown in construction drawing 2 (b)In the situation of the such fiber guide device of guide 30, following making: to adjustment average grain diameterAnd mixed raw material adds adhesive and make blank, by extruding formation method, this blank is configured asBar-shaped and cut into appropriate length, afterwards, similarly burn till with oiling nozzle 10 and obtain sinteringBody, more suitably select necessary grinding or cylinder grinding etc. and process.
