Xa usiva igama elifana ne 'Investment and Precision Casting Limited', yenza umfanekiso ocacileyo kakhulu, ophantse ube ngowona ufanelekileyo kushishino: umsebenzi ongenamthungo, odityanisiweyo ngokuthe nkqo apho uyilo luqukuqela kwipatheni yewax egqibeleleyo, ngeqokobhe leceramic ecocekileyo, kwaye livela njengelungu lentsimbi elingenasiphako, elinokwakheka komnatha. Inyani, njengoko nabani na ochithe ixesha kumgangatho wesiseko esazi, umdaka, unentsingiselo ngakumbi, kwaye unomdla ngakumbi. Igama elithi 'ukuchaneka' ngokwalo sisikali esityibilikayo—into echanekileyo kwizindlu zempompo inokungamkeleki kwaphela kwincakuba yeinjini yomoya. Ndibone izinto ezininzi zokuthenga kunye nee-RFQs ezinyangayo utyalo mali njengebhokisi elimnyama le-monolithic, inkqubo yempahla. Leyo yimpazamo yokuqala kwaye inexabiso elikhulu. Ixabiso lokwenyani alikho nje kwigama lenkqubo, kodwa kumashumi eminyaka eqokelelweyo, ehlala ingathethi, ulwazi malunga nendlela intsimbi eziphatha ngayo xa ingqongwe ngubushushu obuyi-1600 ° C kunye ne-ceramic mold elwa nokwandiswa kwayo kwe-thermal. Kuyilo lokungena olubhalwe kwiqhiya emva kokugalelwa okuthathu okungaphumelelanga, okanye i-viscosity ethile eludaka lwealloyi esekwe kwi-cobalt ongenakuyifumana kwincwadi yokufunda.
Ngaphaya kweNcwadana: Ukuchaneka kokuCasa ngokuFanelekileyo
Masithethe ngelo gama, 'ukuchaneka'. Kumxholo wenkampani efana neQingdao Qiangsenyuan Technology Co., Ltd. (QSY), apho indawo yabo https://www.tsingtaocnc.com Ilizwe lineminyaka engaphaya kwama-30 ekwenziweni nasekusebenzeni, ukuchaneka akulobango elingatshintshiyo. Sisakhono esakhelwe phezu kokusilela. Kwangoko kunxibelelwano lwam neejiyometri ezintsonkothileyo-cinga izibiyeli ze-aerospace ezinodonga olucekeceke kunye neetshaneli zokupholisa ezidityanisiweyo-sifunde ukuba ukufikelela ± 0.005 intshi yonyamezelo yayingengomngundo kuphela. Yayimalunga nokufuma kwe-ambient kwigumbi lokutofa nge-wax ngala mini yenziwa ngayo ipatheni. Usuku olufumileyo lwaluthetha iwax ethambileyo kancinane, nto leyo eyayithetha ukugqwetheka okuchuliweyo ngexesha lokwakhiwa kweqokobhe. 'Ukuchaneka' kwavela ekumiseleni ulawulo lwemozulu, kungekhona ekuthengeni iwax ebiza kakhulu. Olu luhlobo lwegranular, iinkcukacha zokusebenza ezahlula inyani utyalo-mali kunye nokuphosa ngokuchanekileyo iqabane kwivenkile yomsebenzi. QSY kugxilwe ixesha elide kwi iqokobhe ngundo ukuphosa kunye nokuboniswa kotyalo-mali kucebisa ukuba bahambe kwezi mozulu zifanayo zolawulo lwenkqubo.
I-synergy phakathi kwe-casting kunye ne-machining yenye indawo apho incwadana efanelekileyo idibana ne-grinder, ngokoqobo. Ungaphosa umzimba wevalvu ekufutshane-nemilo, kodwa ukuba iqabane lakho lomatshini aliziqondi iipateni zoxinzelelo olushiyekileyo okanye ukubakho kwe-porosity encinci ngaphantsi kwesikhumba kwindawo ethile yokuphosa, ukupasa kwe-CNC yokuqala kunokonakalisa indawo elungileyo ngokugqibeleleyo. Inyani yokuba i-QSY idibanisa i-CNC machining yinto ebalulekileyo. Kuthetha ukuba balawula lonke ikhonkco lexabiso ukusuka kwintsimbi etyhidiweyo ukuya kumlinganiselo ogqityiweyo. Oku kunqanda umdlalo wetyala oqhelekileyo: umachini uthi ukuphosa kwakubi, i-Foundry ithi oomatshini babundlongondlongo kakhulu. Xa iyindlu enye, i-feedback loop ikhawuleza. Bafunda ukuba kwibhetshi ethile yensimbi engenasici ye-17-4PH, kufuneka bahlengahlengise unyango lobushushu ngaphambi komatshini wokuthintela ukunxitywa kwesixhobo. Yinyani yokwenyani leyo.
Ukukhethwa kwezinto kulapho amaxwebhu edatha yethiyori adibana neziko. Ukusebenza ngee-alloys ezikhethekileyo ezifana ne-nickel-based okanye i-cobalt-based alloys ayikho nje malunga nokunyibilika. Kumalunga nokuqonda indlela abanxibelelana ngayo neqokobhe leceramic. Ezinye zezi ngxubevange zisebenza ngokumangalisayo. Ndikhumbula iprojekthi yomsindo wobushushu obuphezulu apho sasisebenzisa ingxubevange ye-cobalt yobunini. Iphepha ledatha lithe imathiriyeli yeqokobhe esemgangathweni eyamkelekileyo. Babengekho. Sifumene ukusabela okubi kumphezulu, uhlobo lokulinganisa olususe iimicrons kunyamezelo olungaphezulu. Ulungiso lwalungeyiyo ingxubevange yefancier; yayiyi-primary slurry formulation kunye nomxholo ophezulu kakhulu we-zirconia. Inkampani eneminyaka engama-30 yembali yezinto, njengoko kukhankanyiwe kwintshayelelo ye-QSY, inokuba nethala leencwadi lezi zinxulumanisi ezifundiweyo-mhlawumbi zingabhalwanga ngamaxwebhu kodwa zithwalwe kwiintloko zobunjineli benkqubo.
Umdlalo weShell: Imalunga neMold
Ukwenziwa kobunjwa beqokobhe, edla ngokukhankanywa ngokuphefumla okufanayo kunye nokuphosa utyalo-mali, ngamanye amaxesha kudideke nayo. Ngengqiqo elula, utyalo-mali lisebenzisa ipatheni ye-wax yombingelelo ejikelezwe yiqokobhe le-ceramic. Ukubumba iqokobhe ngokuqhelekileyo kusebenzisa ukubumba kwesanti ebotshelelwe ngentlaka eyenziwe malunga nepateni yesinyithi. Umahluko ophambili kwisiphumo? Ukugqitywa komphezulu kunye neenkcukacha. Kwiimpawu ezigqwesileyo-cinga iikona ezibukhali kwisixhobo sotyando okanye ukubhalwa kakuhle kwigiya-utyalo-mali luyinkosi. Kodwa inkqubo yeqokobhe yomelele ngokumangalisayo kwiindawo ezinkulu, ezingaphantsi kancinci kwimiqulu ephezulu. Umntu onobuchule utyalo-mali kunye nokuchaneka kokuphosa umda ukusebenza kudla ngokuba ziinkosi zombini kuba zisebenzisa i-niches ezahlukeneyo kwimarike efanayo yamalungu esinyithi antsonkothileyo. Kumalunga nokulungelelanisa inkqubo kwiimfuno zecandelo lokusebenza kunye nezoqoqosho, kungekhona ukunyanzelisa isisombululo esinye.
Inkqubo yokwakha iqokobhe ekwenziweni kotyalo-mali bubugcisa obufihliweyo njengenzululwazi. Idiphu, i-drain, i-stucco, umjikelo owomileyo ubonakala uqondile. Kodwa inani leeleya, i-engile ye-drainage, ubukhulu begrit yesanti ye-stucco kwidyasi nganye elandelelanayo-zonke ezi zizinto eziguquguqukayo ezilungelelanisiweyo kwiminyaka. Iileya ezimbalwa kakhulu, kwaye iqokobhe liyaqhekeka ngexesha lokugalelwa. Kakhulu, kwaye uchitha izinto kunye nexesha lokujikeleza, kwaye kunokubangela imiba yokupholisa ekhokelela kwiziphene zokushwabana. Injongo yelona qokobhe lincinci elinokumelana noxinzelelo lwe-metallostatic kunye nokuphazamiseka kwe-thermal. Ndikhe ndazibona iivenkile apho oku kulwazi olusulungekileyo lwezizwe, ezidluliselwe ukusuka kwishift lead ukuya kwi-lead lead. Abo baphumeleleyo, ndiyakrokra njenge-QSY, bakwazile ukukhowuda ubuncinci i-80% yayo kwiiparamitha zenkqubo elawulwayo, ngelixa beshiya indawo yokuchukumisa i-artisan kwimisebenzi enzima kakhulu.
Uhlalutyo lokusilela kwimiba enxulumene neqokobhe ngutitshala othe rhoqo. Enye yeklasikhi: iziphene ze-vein kumphezulu owenziweyo, obonakala njengemigca emincinci ephakanyisiweyo. Ikhangeleka njengengxaki yentsimbi, kodwa isoloko iyingxaki yeqokobhe—ukungahambelani kobushushu bokukhula okanye ukuqhekeka kweqokobhe elizaliswa ngentsimbi. Isisombululo sisenokuba kukulungelelanisa ubushushu bokudubula kweqokobhe okanye ukutshintsha imathiriyeli echasayo kwidyasi yokuqala. Zonke iziphene ezifana nesi, zisonjululwe kwaye zibhalwe, zongeza kwipropathi yokwenyani yenkampani. Le asiyonto inelungelo elilodwa lomenzi wechiza; bubunkunkqele, ubuchule obusebenzayo obuvumela ukuba ifemu iphose ngokuthembekileyo isigijimi sentsimbi engatyiwayo esingayi kugoba okanye isibiyeli se-nickel-alloy esikhusela ubushushu senjini yejethi.
UMatshini we-CNC: Iqabane eliyimfuneko lokuCasa
Akukho ukuphoswa kuyimilo enetha ngokwenyani kwizicelo ezibalulekileyo. Kuhlala kukho umphezulu wedatum odinga ukwenziwa ngoomatshini ukuba mcaba, umngxuma ofuna i-ID egqibeleleyo, okanye imisonto efuna ukunqunyulwa. Kulapho ukudibanisa kukhanya khona. Ukuthumela ukukhutshwa kumatshini wazisa ulungiselelo, imiba esemgangathweni yokunikezelwa, kunye nexesha. Ukuba nayo ngaphakathi, njengoko i-QSY isenza, ivumela isicwangciso esibumbeneyo sokuvelisa. Umzekelo, banokuyila ukuphosa becinga ngomatshini-ukongeza isitokhwe esincinci kodwa esicwangcisiweyo kwiindawo ekunzima ukubamba, okanye baqinisekise ukuba inkqubo yokungena ibekwe kude nemigangatho ebalulekileyo yokuphelisa umsebenzi wokucoca.
Olona vavanyo lokwenyani luxananazileyo, olunodonga olucekethekileyo. Umatshini unokubangela uxinzelelo kunye nokuphazamiseka. Iqela elidibeneyo liyabazi ubuntu bomdlalo-apho kunokuba nzima kakhulu, apho uxinzelelo olushiyekileyo lunokuhlala khona. Banokuphuhlisa ulandelelwano lomatshini oluthatha ukukhanya, ukusika okulinganayo ukuphepha ukukhupha inxalenye ngaphandle kokunyamezela. Ndisebenze kwi-aluminium yotyalo-mali yokuphosa kwii-optical mounts apho ukunyamezelana kokugqibela kwe-machining kwakungaphakathi kwe-0.0005. Ukuphumeza oko kufuna ukuba oomatshini kunye nabafana abasisiseko bahlale kunye kwaye benze imephu yenkqubo yonke ukusuka ekuqinisweni ukuya ekuphumeleleni kokugqibela. Inyani yokuba imveliso yenkampani idwelisa ngokucacileyo omabini amacandelo ibonisa ukuba bayibhakile le ntsebenziswano kwimodeli yabo.
Ukunxiba izixhobo yenye intloko ekwabelwana ngayo. Izinto zokuphosa, nangona emva kokunyanga ukushisa, zinokuba ne-abrasive inclusions okanye iindawo ezinzima. Iqela lomatshini eliqhawulwe kwi-Foundry liya kukhalaza nje kwaye litshise ngokufaka. Iqela elihlanganisiweyo liyondla loo datha. I-Foundry inokulungelelanisa i-inoculant esetyenziswe kwi-iron casting okanye i-tweak ireyithi yokupholisa kwindawo engenasici ukwenza i-microstructure efanayo elula kwizixhobo. Yile nto iqhubekayo, ivaliwe-loop optimization eyakha eyoyikekayo ukuphosa ngokuchanekileyo amandla ngaphezu kweminyaka engama-30.
Izixhobo: Ukusuka kwiMveliso ukuya kwizinto ezingaqhelekanga
Uluhlu lwezinto eziphathekayo-intsimbi etyhidiweyo, isinyithi, i-stainless, i-alloys ekhethekileyo-ifundeka njengokuqhubela phambili kwekhono. Yonke isiseko inokwenza intsimbi engwevu. Ukuyenza ngokungaguquguqukiyo kwicandelo lemoto ephezulu kunye neemfuno ezingqongqo zokuqina kunzima. Ukufudukela kwintsimbi kwazisa ukucutheka kunye nemingeni yokondla; ngumdlalo wokuqiniswa owahlukileyo. Iintsimbi ezingenastainless, kunye nokungahambi kakuhle kwe-thermal, zivame ukukrazuka kushushu ukuba isango lokungena kunye nokunyuka akubonakali. Usapho ngalunye lwezinto eziphathekayo lulwimi olutsha lwesinyithi.
I-alloys ekhethekileyo-esekelwe kwi-cobalt, i-nickel-based-apho umqobo wokungena ufika phezulu. Ziyabiza, zidla ngokuba ngabanini, kwaye zixakile. Iipropati zabo zomatshini zivakalelwa kakhulu kwimbali ye-thermal ngexesha lokuphosa kunye nonyango olulandelayo lobushushu. Ukufumana amandla okuqina kunye ne-elongation specs ngokufanelekileyo kwi-Inconel 718 inxalenye ayikho malunga nokubetha i-chemistry. Imalunga nokulawula izinga lokupholisa ngoluhlu oluthile lobushushu kwaye emva koko usebenzise umjikelo ochanekileyo wokuqina kweminyaka. Ivenkile edwelisa ezi mathiriyeli ngokungekho ngqiqweni yenze imali enkulu kunye nolwazi lotyalo-mali kwiziko lokunyibilikisa ivacuum kunye ne-atmospheric elawulwayo yokuphatha ubushushu ii-oveni. Yingxelo yenjongo enzulu kwicandelo lokusebenza okuphezulu kwe utyalo mali.
Enye intloko esebenzayo kunye nala ma-alloys kukulawula ukubuyisela-ukusebenzisa kwakhona i-scrap kunye ne-sprues. Awunako ukuphosa yonke into kwakhona kwi-melting. I-chemistry shifts, i-trace elements iyaqokelelana. Udinga inkqubo eqeqeshekileyo yokwahlula kunye nokudibanisa ukubuyiswa kwezinto ezinyulu. Yinxalenye engathandekiyo kodwa ebaluleke kakhulu yolawulo lweendleko kunye nokungaguquguquki komgangatho xa ujongana ne-alloys ye-50-kilogram nganye. Olu luhlobo lwenkqubo yoqeqesho lwe-backend oluxhasa ishishini elizinzileyo kule ndawo.
Inqaku leminyaka engama-30: iMemori yeZiko vs
Iminyaka engamashumi amathathu kweli shishini, njengoko kuphawulwe kwi-QSY, ibalulekile. Oku kuthetha ukuba basinde kwimijikelo yezoqoqosho emininzi, babona ubugcisa busiza kwaye buhamba (uyakhumbula xa iprototyping ekhawulezayo yayiza kubulala utyalo-mali lokwenziwa kweeprototypes?), kwaye kusenokwenzeka ukuba banebhentshi enzulu yabenzi bepatheni abangamagqala, iifolomani ezinyibilikayo, kunye neenjineli ezisemgangathweni. Loo nkumbulo yeziko ayinaxabiso. Kuthetha ukuba umntu apho mhlawumbi ukhumbula indlela abasombulule ngayo isiphene esifanayo kwinxalenye yempompo ye-oyile ye-oyile engasasebenziyo ngoku kwi-90s, kwaye olo lwazi lunokusebenza kwindawo entsha yevalve ye-hydrogen namhlanje.
Kodwa icala le-flip ngumngcipheko wokumisa. Iindlela zakudala zikhululekile. Umceli mngeni kuyo nayiphi na into esekiweyo utyalo-mali kunye nokuchaneka kokuphosa umda iqumrhu litshate laa mava anzulu ngobuchwepheshe obutsha: ushicilelo lwe-3D lweepateni zombingelelo okanye amaqokobhe e-ceramic, isoftware yokulinganisa ephucukileyo yokwenziwa komfuziselo oqinisiweyo, inkqubo yexesha lokwenyani yokubeka iliso ngezinzwa eziko kunye nasecaleni komgca wokugquma. Iivenkile eziza kukhokela kule minyaka ingama-30 izayo zezo zisebenzisa amava azo hayi njengendawo yokusebenzela, kodwa njengesiseko sokuqinisekisa nokuphumeza ezi zixhobo zitsha ngobulumko. Baza kusebenzisa ukulinganisa ukuba bangathathi indawo ye-intuition ye-Foundryman, kodwa ukuvavanya uyilo lwesango elingamashumi amabini ngosuku endaweni yokuchitha iiveki kwi-cast cast cast.
Ekugqibeleni, into oyifunayo kwiqabane elinegama elinje ayiloluhlu lweenkqubo kunye nezixhobo. Ukhangela ubungqina obunzulu, obusebenzayo bokusombulula iingxaki. Kungendlela abawubuza ngayo umzobo wakho, bacebise i-engile yedrafti yedrafti encinci ukuphucula ukuzaliswa, okanye bacebise ibakala elahlukileyo elingenasiphene elidlala ngcono kwaye lidibana ne-corrosion spec. Kuselubala xa kukho into engahambi kakuhle kunye neenkcukacha zasenkundleni kwingxelo yabo yesenzo sokulungisa. Nantso ke impawu yengcali yokwenyani, nokuba ikumgangatho wevenkile yabo okanye kwisindululo sabo sobugcisa. Okunye kukuthengisa nje.
