Xa abantu abaninzi besiva 'indawo yokuphosa iwax elahlekileyo', baba nomfanekiso wentsimbi engenasiphako, entsonkothileyo yentsimbi esetsha kwiqokobhe leceramic. Lowo ngumfanekiso wentengiso. Inyani emgangathweni wevenkile luthethathethwano olungagungqiyo phakathi kwamabhongo oyilo, ukuziphatha kwezinto eziphathekayo, kunye nefiziksi engaxoleliyo yesinyithi esinyibilikisiweyo. Ayibobugcisa kuphela; lulungelelwano olulawulwayo.
I-Core Illusion kunye neNyaniso yeGating
Eyona ngcamango iphosakeleyo kukuba ukugqibelela kwepateni yewax ilingana nenxalenye yokugqibela. Unokuchitha iintsuku usenza imodeli ye-wax eneenkcukacha ezibukhali, kodwa ukuba inkqubo yokungena yingcamango yamva nje, wenza inkunkuma ebizayo. Ndiyibonile amaxesha amaninzi kakhulu: iinjineli ziyila indawo entle, zithumela ifayile yeCAD, kwaye zicingele ukuba umsebenzi we-Foundry kukukopa nje. Umsebenzi wokwenyani uqala ngokuyila indlela intsimbi eya kuhamba ngayo, isondle, kwaye iqine. Elo sprue, imbaleki, kunye noyilo lwesiphaseli? Kulapho idabi liphumelela khona okanye liphulukene phambi kokuba kugalelwe nasiphi na isinyithi.
Umzekelo, ngezinto ezicekethekileyo zentsimbi engenasici, umceli mngeni awugcini nje ngokuzalisa umgodi. Ikhusela i-mistruns ngelixa ilawula ukucutheka kwe-porosity kumacandelo adibeneyo adibeneyo. Awunakusuka nje unyuse ubungakanani besango; ungazisa isiphithiphithi. Yiphazili. Ngamanye amaxesha, isisombululo siquka ukongeza izandiso ze-wax zombingelelo-kungekhona inxalenye yoyilo lokugqibela-kuphela ukwenza njengobunzima be-thermal okanye i-feeders, ezithi kamva zenziwe ngoomatshini. Oku akukho kuyo nayiphi na incwadi; ifundwa ngokuqhekeka utyalo mali iiprototypes.
Apha kulapho amava e-Foundry eba yinto ebonakalayo. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye neminyaka yabo engamashumi amathathu kwi-shell mold kunye utyalo mali, ziya kuba neencwadi zokudlala zangaphakathi kwezi meko. Umsebenzi wabo wexesha elide ucebisa ukuba baye baphinda-phinda ngokuyilwa kwesango lokungena kwemathiriyeli ukusuka kwiintsimbi eziqhelekileyo ukuya kwi-alloys ekhohlisayo esekwe nickel, ukuguqula umngcipheko wethiyori kulwazi lwenkqubo.
I-Material ayikoKhetho nje kwi-Datasheet
Ukukhetha izinto ezifana nensimbi engenasici 316 okanye i-cobalt-based alloy for a ukulahlwa kwewax elahlekileyo inxalenye yintshukumo nje yokuvula. Ukuziphatha kwe-alloy ngexesha lenkqubo yokuphosa utyalo-mali kuyalela yonke into ukusuka kumaqondo obushushu angaphambi kobushushu ukuya kwixesha le-shakeout. 304 xa kuthelekiswa no-316, ayithethi nje ngokuxhathisa umhlwa; baneendlela ezahlukeneyo zokuqiniswa. I-316 idla ngokuxolela ngakumbi ngokukrazula okutshisayo, kodwa kwakhona i-viscous ngakumbi xa ityhidiweyo, ifuna ukulungiswa kwiqondo lokushisa kunye nesantya.
Ukusebenza nge-alloys ezikhethekileyo, njenge-nickel okanye i-cobalt-based based based QSY ikhankanya, iyakwandisa oku. Ezi zidla ngokuba zezoxinzelelo oluphezulu, izicelo zobushushu obuphezulu-cinga iiblade ze-iturbine okanye izakhi zevalvu. Ixabiso lemathiriyeli ekrwada iyodwa lenza ukuba uvavanyo kunye nempazamo luthintele. Ipateni ye-wax, ukwakhiwa kweqokobhe, kunye nomjikelo wokudubula zonke kufuneka zilungiswe. Iqokobhe elisebenza ngokugqibeleleyo kwintsimbi yekhabhoni linokubangela umaleko wokusabela okanye ukuqhekeka kancinci nge-alloy nickel esebenzayo. Ufunda ukuhlonipha ubuntu bezinto eziphathekayo, hayi nje iipropathi zayo zeshiti.
Ukusilela ndikhumbula kwakubandakanya inxalenye yemali. Ukusatywa kwakukhangeleka kuvakala, kodwa ngexesha lomatshini, uthungelwano lweentanda ezintle zavela nje ngaphantsi komhlaba. Umoni? Iqokobhe lalingangeneli kakhulu, libamba iigesi ngexesha lokugalelwa. Isisombululo yayikukuhlengahlengisa istucco sesanti kwiidyasi eziphambili ukwenza iqokobhe elingenamoya ngakumbi. Yayiyinto efihlakeleyo, phantse engabonakaliyo kwinkqubo eyaba nemiphumo eyintlekele kumdlalo wokugqibela ilahleko yokuphosa iwax.
I-Handoff: Xa i-Casting idibana ne-CNC Machining
Eli lixa elibalulekileyo elijongelwa phantsi ngabathengi abaninzi. Hayi utyalo mali iphuma ilungele ukuhlohla, nokuba athini na amabango emilo yomnatha. Kuhlala kukho iintsalela zesango, imigca yokwahlula, kunye neendawo ezingaphezulu ezifuna ukuchaneka kwemishini. Ukungabikho komthungo phakathi komgangatho wokuphosa kunye nesebe lomatshini yinto echaza umthengisi osemgangathweni. Ukuba oomatshini bahlala besilwa ukufumana indawo yedatha kuba ukuphosa kunokuphazamiseka koxinzelelo lwangaphakathi olungalindelekanga, unengxaki yenkqubo.
Udibaniso lwe-QSY lubalaselisa-ukunikezela zombini ukuphosa kunye ne-CNC machining-ayiyo nje inkonzo yokudibanisa; sisicwangciso solawulo lomgangatho. Xa iziko elifanayo liphatha zombini, banokuyila inkqubo yokuphosa becinga ngomatshini. Banokongeza iilugi zolungelelwaniso kwipatheni ye-wax eziye zibe zizixhobo zoomatshini, okanye bazi kakuhle ukuba singakanani na isitokhwe esinokusishiya kubuso obubalulekileyo ngokusekwe kukwandiswa kweqokobhe labo okungaguqukiyo. Iguqula umdlalo onokubakho wokutyhola phakathi kwabathengisi ababini ube yi-loop elawulwayo, yangaphakathi yengxelo.
Ndibone iiprojekthi zisilela ngenxa yokuba indlu yokulahla kunye nevenkile yomatshini yayinganxibelelani. Ukusaswa bekungaphakathi konyamezelo loshicilelo, kodwa umahluko wenze inkqubo ye-CNC yaba liphupha elibi, ivuthela uhlahlo lwabiwo-mali. Umsebenzi odityanisiweyo ngokuthe nkqo unciphisa oko. Banokuthi, Kolu hlobo lweengcambu zeblade ye-injini yomoya, sifuna i-0.5mm eyongezelelweyo kobu buso ukuze siphumelele umgangatho wethu wokucoca, kwaye siyibhake kwi-wax die design ukususela kusuku lokuqala.
Iqokobhe: Uzwilakhe Othuleyo
Ngelixa i-wax ifumana ingqalelo, iqokobhe le-ceramic ligorha elingavunywanga-okanye i-villain efihliweyo-yayo yonke into ukulahlwa kwewax elahlekileyo. Ukwenziwa kobunjwa beqokobhe, okanye inkqubo yeqokobhe le-ceramic kwi-investment casting, sisithethe seentsuku ezininzi sokuntywila, ukufaka istucco, kunye nokomisa. Ubukhulu bomaleko ngamnye, ukuxinana, kunye neempawu zobushushu zibalulekile. Iingqimba ezimbalwa kakhulu, kwaye igobolondo iyaqhekeka ngexesha lokuthulula. Ininzi kakhulu, kwaye iba yi-insulating iguqula ireyithi yokuqina, ekhokelela kwiziphene zokuncipha.
Ukukhethwa kwe-binder kunye nokutshintsha kwezinto ezichasayo ngokusekelwe kwintsimbi egalelwe. Kwi-alloys ephezulu yokushisa, i-zircon-based face coat iqhelekile ukukhusela ukusebenzisana kweekhemikhali. Indawo yokomisa (ukufuma, ubushushu) phakathi kweedyasi ibalulekile. Ukungxama kweli nqanaba kuqinisekisa ubuthathaka beqokobhe. Yinkqubo echasene ne-automation kwiindawo zayo ezintle; ifuna amagcisa ayakwazi ukufunda umbala nesandi seqokobhe xa ecofa.
Umzekelo ovela kumsebenzi we-aerospace: kwinxalenye ecekethekileyo, emide ye-aluminiyam, sisebenzise iqokobhe elixubileyo elinefayibha eyomeleziweyo yogcino umaleko ukunika amandla aluhlaza ngexesha lokukhutshwa kwewaxing, kodwa idyasi entle kakhulu ukubamba iinkcukacha zomhlaba. Yayiyiresiphi yesiko eyaphuhliswa emva kokuphindaphinda kaninzi apho iinxalenye zazinokujika okanye ziqhekeke ngexesha le-autoclave dewax. Iresiphi yeqokobhe idla ngokuba yeyona propati igadwayo kwi-Foundry.
UQoqosho lweSikali kunye ne-One-Offs
Kukho ingcamango egcweleyo ukulahlwa kwewax elahlekileyo yenzelwe imveliso eninzi kuphela. Ayonyani. Ngelixa isixhobo sokuqala (isinyithi sifa ngenxa yokutofa kwe-wax) lutyalo-mali, inkqubo iguquguquka ngokumangalisayo kwimithamo ephantsi kunye neeprototypes. Unokwenza umatshini wepatheni ye-master kwiplastiki okanye umthi, wenze i-silicone mold, kwaye uvelise iipateni ze-wax ngesandla kwiindawo ezincinci. Indawo yokuphumla ngokuchasene nokugalelwa kwesanti okanye ukwenziwa kwezinto kwehla kubunzima bejometri kunye nokugqitywa okufunekayo.
Kwi-manifold entsonkothileyo enokufuna amacandelo adityanisiweyo amaninzi kunye nomatshini obanzi wangaphakathi, omnye utyalo mali inokuba nexabiso eliphantsi nanjengoko i-off-off, xa ubala umsebenzi opheleleyo. Iindleko azikho kwintsimbi kuphela; kukuphetshwa iiyure machining kunye nendibano. I-Foundry efana ne-QSY, esebenza kwisikali, mhlawumbi ineenkqubo zokuphatha ngokufanelekileyo zombini ii-odolo zebhetshi ezinkulu ze-impellers zempompo kunye neeprojekthi ezincinci, eziphuhlisayo zamacandelo akhethekileyo e-alloy, usebenzisa izicwangciso zezixhobo eziguquguqukayo.
Owona mgibe woqoqosho lutshintsho lwenkqubo ephakathi. Ukutshintsha uyilo lwenxalenye emva kokwenziwa kokungunda kwenaliti yewax kuyabiza. Kwanotshintsho oluncinci lunokuthetha ukukrazula i-mold yentsimbi eqinile kwaye uqale phantsi. Yiyo loo nto intsebenziswano yangaphambili-uyilo lokuphononongwa kokwenziwa kwezinto-sesona sigaba sibaluleke kakhulu. Kulapho iinjineli zesiseko ezinamava zinokubonisa, Le ndawo yekona yangaphakathi iya kubangela ukuncipha. Ukuba siyayinyusa nge-1mm, sinokuqinisekisa ukuvakala ngaphandle kokuchaphazela umsebenzi wakho, sigcina amawaka ezantsi emgceni.
Ingcamango yokuGqibela: Licebo eliZifihlwe njengeNkqubo
Ekupheleni kosuku, ukuvelisa ethembekileyo ilahleko yokuphosa iwax ihlala ingumxube wenzululwazi kunye nobugcisa obunexesha elide. Iimodeli ze-CAD kunye nesoftware yokulinganisa zibangcono minyaka le, kodwa azikwazi kuphendula ngokufuma okusemoyeni ngemini yomiswa kweqokobhe okanye umahluko ofihlakeleyo kwi-alloy enyibilikayo kwibhetshi entsha yokutya. Kulapho iminyaka engama-30 yembali ye-Foundry, njenge-QSY's, ifakwe kwiindawo-kungekhona kwi-logo, kodwa kwisakhiwo esingaguqukiyo senkozo ye-valve yogcino loxinzelelo okanye indawo engenasiphako ye-marine fitting.
Injongo asikokwenza nje imilo. Kukwenza imilo esebenza phantsi koxinzelelo, ubushushu, okanye umhlwa, ibhetshi emva kwebhetshi. Oko kuthembeka kwakhiwe kwiwaka elincinci, izigqibo ezichanekileyo ezenziwe kwigumbi le-wax ukuya kwisithando somlilo sokushisa. Imdaka, iyaphindaphindeka, kwaye ikude nomfanekiso wencwadana emenyezelayo, kodwa yiloo nto eyenza intsimbi esebenzayo, enentembeko ephezulu.
