Xa usiva 'umvelisi wotyalo-mali oluchanekileyo,' uninzi lweengqondo zitsibela ngqo kunyamezelo oluqinileyo kunye neejometri ezintsonkothileyo. Kuchanekile oko, kodwa kukwalapho umngxunya omkhulu ulele khona. Owona mceli mngeni ayikokufikelela nje amanani kumzobo; iyazigcina ngokuqhubekayo kuyo yonke imveliso eqhutywayo ngelixa ilawula izinto eziguquguqukayo uninzi lwabathengi abangaze bayibone-efana newax yokudibanisa i-viscosity ukusuka kwibhetshi ukuya kwibhetshi, okanye indlela ukufuma kwengingqi ngoLwesibini emva kwemini kunokuchaphazela izinga lokomisa kweqokobhe leceramic. Abathengi abaninzi bathenga ngokusekwe kwisakhono esidwelisiweyo, yithi, ± 0.005 intshi, ngaphandle kokubuza malunga nenkqubo yolawulo lwenkqubo eyinikezela ngokwenene. Kulapho ukwahlukana kokwenyani phakathi kweevenkile zemisebenzi kunye nabavelisi bokwenyani kwenzeka.
Isiseko: Iqala phambi kweWax
Awukwazi ukuthetha ngokuchaneka ngaphandle kokuthetha ngepateni. Uninzi lwabasanda kufika ebaleni bacinga ukuba umlingo uyenzeka ezikweni. Kumava am, ngaphezulu kwe-60% yeempazamo ezinobungakanani obunokuthi zitshixelwe kwinqanaba lesixhobo kunye ne-wax yokutofa. Ukuba umngundo awulunganga, uphinda-phinda ukungafezeki ngokuthembeka okuphezulu. Ndizibonile iiprojekthi apho umxhasi ebonelele nge-aluminiyam emhle, eyenziwe ngoomatshini, kodwa akazange acinge ngokushwabana okubini—okokuqala kwe-wax, emva koko kwentsimbi. Kuye kwafuneka sakhe oko kuncipha kongezelekayo kanye kuyilo lwethu lwezixhobo. Yincoko malunga nee-coefficients, hayi nje ukukopa imilo.
Apha kulapho imbali yokusebenza ende ibalulekile. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kule minyaka ingama-30 isenzayo nokwenza oomatshini, kusenokwenzeka ukuba iye yakha yaza yaphindaphinda amawaka ezi zixhobo. Lo vimba wedatha yezinto zokuziphatha-kanjani ethile intsimbi engenasici ibakala liyacutheka xa lithelekiswa ne-a ialloy esekwe nickel—ayisiyonto oyifumanayo kwincwadi yesifundo. Ibhalwe kumaphepha enkqubo yabo. Ukutyelela indawo yabo e tsngtaocnc.com, uyabubona ubunzulu bobo; ikuluhlu olucwangcisiweyo lokungunda olugcinwe kakuhle, hayi nje oomatshini abatsha abenyezelayo.
Igumbi le-wax ngokwalo liyi-ecosystem elawulwa yimozulu. Ubushushu bufuna ukuzinza, kungekhona nje 'ukukhululeka.' Ukuguquguquka kwamaqondo ambalwa kunokutshintsha iimpawu zokuhamba, okukhokelela kwiiyantlukwano ezincinci kubukhulu bodonga olubonakala kuphela emva kokugalelwa kwesinyithi. Sifunde oku ngendlela enzima kwi-odolo ye-aerospace yangaphambili ye-sensor housings. Amalungu aphumelele ukuhlolwa kokuqala, kodwa akuphumelelanga kwinqanaba lokuhlanganisa kamva ngenxa yokungahambelani kobunzima beembambo zangaphakathi. Oyena nobangela? Uyilo olungabhaqwanga kucango lweworkshop lwalubangela ukuthambeka okufihlakeleyo kobushushu kufutshane nomshicileli wokutofa. Yayisisifundo esithobekileyo, esibiza imali eninzi kulawulo lokusingqongileyo.
Iqokobhe: Apho iKhemistry idibana khona neCraft
Inkqubo yokwakha iqokobhe leceramic idla ngokuchazwa njengenzululwazi. Yiyo, kodwa kukho into ebalulekileyo yobugcisa kwigumbi elinodaka. Ukubunjwa kwedyasi ephambili ye-slurry ibalulekile ekugqityweni komphezulu, kodwa isicelo se-stucco-indlela ezo zikhwebu, ezinqabileyo ezisetyenziswa ngayo-zichaphazela i-shell permeability kunye namandla. Undlongondlongo kakhulu, kwaye ubethelela uxinzelelo; uthambile kakhulu, kwaye ufumana iindawo ezibuthathaka. Sisakhono esichukumisayo esiphuhliswa ngabaqhubi ngokuhamba kweminyaka.
Ixesha lokumisa phakathi kweedyasi yenye into ebalulekileyo, kwaye ihlala ijongelwa phantsi. Ukuyingxamela ukuhlangabezana neshedyuli yindlela eqinisekileyo yokwazisa ukuqhekeka kweqokobhe okanye i-delamination. Ezi ziphene zisenokungabangeli indawo echithwe kanye, kodwa zinokukhokelela kumaphiko omphezulu okanye uburhabaxa obuncinane obubulala 'ukuchaneka' kumatshini wasemva komatshini. Ndikhumbula ibhetshi yomzimba wevalve yehydraulic apho sajongana nomngxuma womphezulu ongaqondakaliyo. Emva kokulawula umgangatho wesinyithi, siyilandelele emva kwigcisa elitsha elalipakisha iipateni eziditshiweyo kufutshane kakhulu kwigumbi lokomisa, lithintela ukuhamba komoya kunye nokubambisa ukufuma kumaleko eqokobhe.
Kuba ialloys ezifana cobalt-based okanye ezo zisekwe kwi-nickel ezidweliswe yi-QSY, ezihlala zigalelwa kumaqondo obushushu aphezulu kakhulu, ukuxhathisa ubushushu beqokobhe yeyona nto ibalulekileyo. Uqulunqo apha lunokwahluka kuleyo isetyenziselwa umgangatho intsimbi. Inokubandakanya imixube ethile ye-zirconia. Lo ayingomsebenzi weqokobhe elinye; imathiriyeli iyalela inkqubo.
Ukugalela kunye nokuqinisa: Umzuzu weNyaniso
Apha kulapho wonke umsebenzi wokulungiselela uvavanywa khona. Inzuzo yotyalo-mali oluchanekileyo kukuqiniswa kwecala-ukulawula ukuba intsimbi iphola njani ukunciphisa ukushwabana kwe-porosity. Akukhona nje malunga nokufudumeza isinyithi kunye nokugalela kuyo; imalunga pre-ukufudumeza iqokobhe kwiqondo lobushushu ethile (nto leyo iyahluka nge ingxubevange), ukulawula isantya ukugalela, kwaye ngamanye amaxesha nkqu nokusebenzisa igodola-ukufakwa metallic kumngundo-ukunyanzela utsalo ubushushu ngokulandelelana ethile.
Ukufumana oku kungalunganga nge-alloy yexabiso eliphezulu yimpazamo ebiza kakhulu. Sakhe sasebenza ngokuqhutywa kweeblade ze-injini ukusuka kwi-nickel alloy yobunini. I-metallurgy yayivakala, igobolondo yayibonakala igqibelele, kodwa sasine-40% ye-scrap rate ukusuka kwi-micro-porosity yangaphakathi. Ingxaki? Iqokobhe lobushushu bangaphambi kobushushu belimalunga ne-50°C lisezantsi kakhulu kulwaluko oluthile lwe-alloy kunye neempawu zokutyisa. Intsimbi yayikhenkceza ngokukhawuleza, ingavumeli iziphakamisi ukuba zondle ngokufanelekileyo ukugalela. Ukulungiswa kwaba luhlengahlengiso olulula lobushushu, kodwa ukuyixilonga kufuna iindawo zokunqunqa, ukwenza uhlalutyo lwe-metallographic, kunye nokukrazula intloko eninzi.
Esi sigaba sigxininisa ukuba kutheni sidityanisiwe CNC Machining ubunakho busengqiqweni, phantse buyimfuneko, ukwandiswa kwento enzulu utyalo mali umenzi. Kwi-QSY, ukuba noomatshini ngaphakathi endlwini ayikokongeza nje imisonto okanye ukugqiba ubuso. Ivumela i-loop yengxelo. Umchwephesha odibana nendawo enzima okanye i-porosity engalindelekanga kwindawo ethile yokuphosa unokuhamba ngokuthe ngqo kumgangatho wesiseko. Olo nxibelelwano lukhawulezileyo lunceda ukukhomba ukuba ibiyingxaki yokungena, iqokobhe elibuthathaka, okanye into enyibilikayo. Ivala iluphu esemgangathweni.
I-Post-Cast: Amanyathelo alula ngokukhohlisa
I-Knock-out, i-cut-off, kunye nonyango lobushushu. Ezi zivakala njengezinyathelo zamandla emva kokucolwa kokwakhiwa kweqokobhe kunye nokugalelwa, kodwa zibuthathaka ngokwazo. Ukususwa kweqokobhe elingcangcazelayo kufuneka kunyanzeleke ngokwaneleyo ukophula i-ceramic kodwa kungabi ndlongondlongo kangangokuba konakalise amacandelo amancinci esinyithi esomeleleyo ngoku. Ndibone iicastings ezintle, ezintsonkothileyo ziqhekeka yinkqubo enomdla kakhulu yokukhupha.
Ukunyangwa kobushushu yinto ekhethekileyo yayo, ngakumbi ngezinto eziphambili. Intsimbi esemgangathweni engenastainless inokufuna isiqabu soxinzelelo olulula. Imvula-eqinisa i-stainless okanye isixhobo sentsimbi sidinga umjikelo othe ngqo wokufudumeza, ukufunxa, kunye nokupholisa ukuphumeza iipropati ezichaziweyo zoomatshini. Ukuba ukuphosa kuya kuba ngumthwalo osebenzayo wecandelo, eli nyathelo libaluleke kakhulu njengokuphosa ngokwalo. Ngomnye ummandla apho amashumi eminyaka amava, afana namashumi amathathu eminyaka e-QSY, ehlawulayo-kusenokwenzeka ukuba baye baseka kwaye baqinisekisa iiprothokholi zokuphatha ubushushu kwi-matrix enkulu ye-alloy specs.
Eli ikwalinqanaba apho uhlolo lokuqala lwenzeka khona. Uhlolo lwenqaku lokuqala luphelele, luhlala lubandakanya i-CMM (Ukulungelelanisa uMatshini wokuLinganisa) ukuqinisekisa yonke imilinganiselo ebalulekileyo ngokuchasene nemodeli ye-3D. Kodwa uvavanyo lokwenyani luhlolo lwenkqubo ngexesha lemveliso. Uyisampula njani? Ithini i-AQL yakho (iNqanaba loMgangatho elamkelekileyo)? Umvelisi oxabisa ityuwa uya kuba nesicwangciso esicacileyo, esisekelwe kwizibalo, kungekhona nje isithembiso 'sokukhangela ezimbalwa.'
Ukuchaneka kokwenyani: Ukungaguquguquki kunye noNxibelelwano
Ngoko ke, yintoni echaza ngokwenene a umenzi wotyalo-mali oluchanekileyo? Ayiyiyo enye, inxalenye yeprototype egqibeleleyo. Kukukwazi ukuhambisa inxalenye ye-500 ekubalekeni okungaqondakaliyo ukusuka kwi-1 kunye ne-50. Oko kuhambelanayo kuyimveliso yeenkqubo ezilawulwayo, ezibhaliweyo, kunye neziqondwa ngokunzulu kwinqanaba ngalinye-ukusuka kwi-wax ukuya ekuhlolweni kokugqibela.
Esinye isiqingatha lunxibelelwano. Ezona projekthi zibalaseleyo endikhe ndabandakanyeka kuzo zibonise incoko yababini evulekileyo kunye neenjineli zabathengi. Ngamanye amaxesha, i-tweak yoyilo oluncinci-ukongeza i-radius, ukulungelelanisa i-gradient ye-wall-thight-gradient-inokwenza inxalenye enqabileyo kakhulu ngaphandle kokuchaphazela umsebenzi wayo, ngaloo ndlela iphucula isivuno kunye nokuthembeka. Umvelisi osebenza ngokugqibeleleyo njengomthathi-odolo akasayi kukunika loo nto. Omnye oliqabane uya kwenza. Ukujonga imodeli edibeneyo ye-QSY ye iqokobhe ngundo ukuphosa, utyalo mali, kunye nokwenza, icebisa ukuba zakhiwe ukuba zibe nombono opheleleyo wenxalenye yokwenziwa, ekwaziyo ukucebisa ngeyona ndlela ilungileyo ukusuka kwingcamango ukuya kwicandelo eligqityiweyo.
Ekugqibeleni, ukuchaneka yinkcubeko, kungekhona ukusetwa komatshini. Ngumsebenzi oqaphela ukuba i-wax ibonakala yahluke kancinane namhlanje, i-metallurgist ebuza itshati yokuphatha ubushushu, kunye nomphathi womgangatho ogxininisa kuhlalutyo lwengcambu ye-outlier enye. Xa uvavanya umenzi, jonga ngaphaya koluhlu lwamandla encwadana. Buza ngamanqaku abo olawulo lwenkqubo, iinkqubo zabo zokuhlalutya ukusilela, kunye nendlela isiseko sabo kunye noomatshini abathetha ngayo omnye komnye. Kulapho uya kufumana ukuchaneka kokwenyani.
