Iyo wunvise 'ceramic core for investment casting', benshi batekereza ko ari ikibanza gusa, uburyo bwo gutamba. Ngiyo imyumvire ya mbere itari yo. Mubyukuri, ni umwubatsi wimbere imbere. Intangiriro idakozwe neza irashobora gusenyuka, guhinduranya, cyangwa kunanirwa gusohoka, gusiba icyuma cyose cya turbine cyangwa imiti yatewe. Nabonye amaduka ashinja amavuta cyangwa igikonoshwa, gusa nasanze intandaro yari intandaro idashobora kwihanganira ihungabana ryumuriro wa superalloy. Ntabwo ari ibice; ni ukwitanga neza kuva mugitangira cyizunguruka.
Ibikoresho ntabwo ari Ceramic gusa
Kubita a ceramic core ni nko guhamagara ibyuma 'icyuma'. Ibigize byose. Cores ishingiye kuri silika irasanzwe, ariko kuri nikel nyinshi ya nikel yasutswe hejuru ya 1500 ° C, urareba sisitemu ya alumina cyangwa zirconiya. Itandukaniro ntabwo ari igipimo cy'ubushyuhe gusa. Coefficient yo kwagura ubushyuhe (CTE) igomba kuba yarakozwe kugirango ihuze ibishishwa bikikije. Kudahuza, niyo byaba bito, bitera guhangayika mugihe cyo gukonja. Ndibuka umushinga wa a cobalt manifold aho twakoresheje off-the-shelf alumina core. Byasaga neza nyuma ya dewax, ariko nyuma yo gusuka, micro-crack muri core yahinduwe mubice byo hejuru kumiyoboro yimbere. Ibikoresho by'ibanze byari 'byiza', ariko ntabwo byari 'byiza'.
Noneho hariho sisitemu yo guhuza. Ntabwo ari ugufata ibinyampeke gusa mugihe cyicyatsi. Byerekeranye no gusenyuka kugenzurwa mugihe cyo kurasa kugirango ushireho imbaraga zanyuma kandi, cyane cyane, kugenzurwa no gusenyuka muri caustic nyuma. Ibikoresho bimwe na bimwe bya silika ishingiye kuri silike ikoresha binder isiga icyiciro cyoroshye, cyikirahure, bigatuma gikunda kwangirika. Ubuhanga nyabwo ni ugutegura ibikoresho bifite imbaraga zihagije zo kurokoka kubaka ibishishwa no gusuka, nyamara bigahinduka intege nke za chimique kuburyo byakurwaho nta buryo bwubukanishi bushobora kwangiza inkuta zoroshye.
Aha niho uburambe hamwe nibisobanuro byihariye bitanga umusaruro. Gukorana na nikel, nkurugero, uriga bafite intera ndende yo gukomera hamwe na fluid fluid nyinshi. Intangiriro ikeneye imbaraga zidasanzwe kugirango irwanye ibyuma byinjira nisuri igihe kirekire. Intego rusange-nyamukuru irashobora gukaraba, igasiga imbere yimbere yica umwuka mubice bya turbine. Nukunanirwa guceceka - urabibona gusa mugihe cya X-ray cyangwa ibizamini bitemba.
Igishushanyo: Aho Igitekerezo gihurira Igorofa
Moderi ya CAD iratunganye. Ibyingenzi ntabwo. Ikinyuranyo kinini ni mubishushanyo mbonera no gushyigikirwa. Abashushanya akenshi bifuza zeru kumiterere yimbere kugirango barusheho gukora neza indege cyangwa hydraulic. Ariko intangiriro nikintu gifatika kigomba gusohoka mu rupfu cyangwa kanda mubikoresho. Twarwanye imyaka myinshi. Kwiyunga akenshi ni umushinga muto, vuga 0.5 kugeza kuri 1 dogere, ufatanije no gukoresha ingamba zo gucapa ibyingenzi-ubwo bwaguke bushakisha kandi bugashyira intangiriro muburyo bwibishashara hanyuma igishishwa.
Ndibuka ibishushanyo mbonera bya peteroli nozzle kubirere. Uwiteka ceramic core yari afite amaboko menshi yoroheje, ya kantileveri. Mu kwigana, byari bihamye. Mu myitozo, mugihe cyo gutera inshusho ibishashara bikikije, igitutu cyateje gutandukana. Igisubizo? Ubunini bwurukuta butandukanye kurenza urugero. Gukosora ntabwo byari byiza; yari yongeye gushushanya amarembo yo guteramo ibishashara no kongeramo inkunga ya ceramic yigihe gito (nyuma ikurwaho mugusya) kugirango ifatanye intangiriro muricyo gikorwa. Yongeyeho ikiguzi n'intambwe, ariko yakijije igice. Ubu ni bwo bwoko gushora imari nuance udasanga mubitabo.
Ubundi kubabara umutwe ni ingirakamaro. Nkuko icyuma gishongeshejwe cyuzura umwobo, umwuka wafashwe imbere muriwo ugomba guhunga. Niba bidashoboka, umuvuduko winyuma urinda kuzura byuzuye, cyangwa gaze igwa mumutego. Ducukura utwobo duto duto mubice bidakomeye byibanze, ariko kubishyira mubuhanzi. Benshi cyane bagabanya intangiriro; bike cyane bitera inenge. Numuhamagaro wurubanza ushingiye kubunini bwa geometrike na geometrie, akenshi binonosorwa binyuze mubigeragezo.
Ubufatanye nuwakoze inzobere
Ntabwo aribicuruzwa utumiza kurutonde. Nibikorwa byiterambere. Mu myaka yashize, twishingikirije cyane kubahanga. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) Azana agaciro kihariye hano. Hamwe nimyaka 30 yabo Igikonoshwa na gushora imari, basobanukiwe inzira zose. Iyo muganiriye kubishushanyo mbonera hamwe nabo, ntabwo baba batekereza kubyingenzi gusa. Barimo batekereza uburyo ikorana na sisitemu ya shell, autoclave ya dewaxing, imyitozo yo gusuka kuri ibyuma bitandukanye na a idasanzwe.
Nasuye ikigo cyabo inshuro imwe, nsubiramo umushinga wumubiri wa valve mubyuma bya duplex bitagira umuyonga. Intangiriro yari ifite umufuka wimbitse, ufunganye. Injeniyeri wabo yahise yerekana ikibazo gishobora gusohoka. Icyifuzo cyabo kwari uguhindura gato igipimo cyumufuka no kwerekana imiterere yibanze muri kariya karere kugirango yihutishe gusesa imiti. Ibyo nibitekerezo bihujwe. Bituruka ku kugira Uwiteka Imashini ya CNC ubushobozi murugo no - barashobora guhindura byihuse ibikoresho bya shashara bipfa gushingira kubitekerezo byatanzwe mubigeragezo byambere, bigabanya iterambere ryiterambere. Urashobora kubona uburyo bwabo kurubuga rwabo kuri https://www.tsingtaocnc.com.
Umubano ni urufunguzo kuko nyuma yibikorwa bimaze gukorwa, inshingano ntizirangira. Hano hari ingingo ya mbere igenzura, akenshi ikoresha CT gusikana kugirango ugereranye intoki za ceramic zarashwe na moderi ya CAD, kugenzura kugoreka. Noneho hariho inzira yo gutunganya intandaro yo guterwa ibishashara bipfa. Inzobere ikora ibintu byinshi izatanga ibikoresho cyangwa protocole irambuye. Ibicuruzwa rusange bitanga gusa agasanduku k'ibice byoroshye.
Kunanirwa ni Data Ingingo
Ntabwo wigeze ukorana ceramic cores kugeza igihe wagize gutsindwa bidasanzwe. Imwe ifatanye nanjye yari iy'inganda nini ya pompe yinganda. Imirambo yari nini kandi ikomeye. Barashe neza kandi barokoka inyubako. Isuka ya icyuma byagenze neza. Ikibazo cyagaragaye mugihe cyo guhungabana. Intangiriro ntishobora gusohoka. Twagerageje kwaguka kwinshi, guhagarika ubushyuhe, ndetse no kwiyuhagira ultrasonic. Ibice byakomeje guhuzwa mubice byimbere. Post-mortem yerekanye ikibazo: binder yibanze yari yarahuye numwanda wihariye mubumba ryakoreshwaga mu ikoti ryambere ryigishishwa cyigikonoshwa, bituma habaho intera yububiko bwa ceramic yubushyuhe bwinshi. Ibikoresho by'ibanze byari byiza. Igikonoshwa cyari cyiza. Ariko guhuza kwabo, muribihe byihariye, byari bibi.
Ibyo kunanirwa byatwigishije guhora dukora ikizamini cyo guhuza-kurasa agace gato kibanze kuri sisitemu nyayo ya shell slurry turateganya gukoresha, hanyuma tukareba kugenzura. Nintambwe yoroshye ubu isanzwe muburyo bwacu. Byanyigishije kandi ko muri gushora imari, buri kintu cyose kigize sisitemu. Ntushobora guhitamo imwe mu cyuho.
Ikindi gisanzwe, cyicecekeye kunanirwa ni drift. Intangiriro irashobora kuba nziza kubice 100 byambere, hanyuma ugatangira kubona icyerekezo kigana imipaka yo kwihanganira hejuru. Akenshi ni ibikoresho-bipfa gukoreshwa mu gukora ibishashara-bishira hasi. Cyangwa birashobora kuba impinduka zoroshye muburyo bwo gucana. Gufata ibi bisaba kugenzura uburyo bukomeye bwibarurishamibare, ntibipima gusa umukino wanyuma, ahubwo ni ceramic yibanze mubyiciro byinshi. Birarambiranye, ariko birinda ibiza kugenda buhoro.
Amafaranga atishyurwa
Iyo byose bishyize hamwe, the ceramic core nicyo gishoboza gutora bidashoboka. Tekereza icyuma cya turbine cyuzuye gifite imiyoboro ikonje ikurikiza ikirere cya airfoil. Nta bundi buryo bushobora kugera kuri as-geometrie y'imbere. Agaciro ntabwo ari mukurema umwanya wuzuye; ni mukurema inzira yubushakashatsi bwakozwe neza butuma moteri ikora ishyushye, neza. Aho niho ikiguzi kinini cyo kwiteza imbere no gutanga aya mahame gifite ishingiro.
Kuri sosiyete nka QSY, umurimo we ukomoka mu nganda icyuma ibice kugirango bikore neza cobalt, tekinoroji yibanze ni ikiraro hagati yaya masoko. Amahame ni amwe, ariko umunzani wo gukora muburyo bwuzuye na siyanse yibintu. Ubushobozi bwo kuyobora iyo spekure munsi yinzu imwe nicyo gitandukanya iduka ryakazi nabafatanyabikorwa nyabo.
Ubutaha rero iyo urebye ibintu bigoye gushora imari, ibuka umugongo utagaragara imbere. Ibyo ceramic core yatangiriye nka paste, yashizweho, irasa, ikorwa, izengurutswe n'ibishashara, irisiga, irongera irasa, irohama mucyuma gishongeshejwe, amaherezo irashonga. Kubaho kwayo nigikorwa cyigihe gito cyibisobanuro, hasigara gusa akavuyo keza. Kubona ubwo burenganzira ni kimwe cya kabiri cyintambara yo gukora casting itari nziza gusa, ariko ikwiye guhaguruka, icyiciro-cyatewe, cyangwa ubutumwa-bukomeye. Ntabwo ari umwanya gusa.
