Xa usiva 'utyalo-mali lwasekhaya,' uninzi lweengqondo lutsibela kwezo vidiyo zikaYouTube-umfana osegaraji, enyibilikisa iitoti zesoda ngeziko elenziwe ekhaya. Kulungile kwii-trinkets, kodwa lihlabathi elikude ngokuchanekileyo kunye nesayensi yezinto eziphathekayo ezifunekayo ekusebenzeni, iindawo ezithwala umthwalo. Umsantsa wokwenyani ekuqondeni, ndiwufumene, uphakathi kwenkqubo yenqanaba lobuchwephesha kunye noqeqesho loshishino olufunekayo ukwenza into engabukeki nje njengenxalenye yentsimbi, kodwa iqhube njengenye ngokungaguqukiyo. Akukho malunga nokugalela; imalunga nayo yonke into eyenzekayo ngaphambi nasemva kwayo.
Umdlalo weShell: Ngakumbi kunokuDipha kunye nokuThontsiza
Masithethe ngeqokobhe. Isihlwele se-DIY sihlala sisebenzisa imixube ye-plaster-silica elula, apho izinto ziqala ukungahambi kakuhle kuyo nayiphi na into engaphaya kokusetyenziswa kokuhlobisa. Kuseto olululo, njengale nto siyilungisileyo Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), iqokobhe ngumqobo wobunjineli obunemigangatho emininzi. Iqala ngengubo ephambili-umgubo we-zircon ocolekileyo kakhulu okanye into efanayo-ukubamba iinkcukacha zomhlaba. Emva koko uyakha ngeesanti ezirhabaxa ezirhaxayo. Umaleko ngamnye ufuna iimeko zokomisa ezichanekileyo; ulawulo lokufuma lubalulekile. Ndiyibonile imizamo apho ukomiswa ngokukhawuleza kukhokelela ekuqhekekeni kweqokobhe ngexesha lokukhupha i-waxing, ilahleko iyonke. Iqokobhe alikho nje ukungunda; yinto yokutsala ukothuka kwe-thermal ngexesha lokugalela.
Apha kulapho ukhetho lwemathiriyeli yeqokobhe lubophelela khona ngokuthe ngqo kwintsimbi oyiphosayo. Ngaba ugalela i-nickel-based alloy esekwe kwiqokobhe elenzelwe ialuminiyam enyibilikayo ephantsi? Intlekele. Iqokobhe kufuneka libe nenqanaba eliphezulu le-sintering kunye nokuzinza kwe-thermal. Sigcina imigca eludaka olwahlukileyo kwiintsapho ezahlukeneyo eziphathekayo kuba ungcoliseko olunqamlezayo lungonakalisa i-refractoriness. Yinkcukacha ehlala ingahoywa xa abantu becinga ukuba bangasebenzisa iresiphi enye 'yomhlaba wonke'.
Inkqubo ye-stuccoing-ukuphosa intlabathi erhabaxa kwi-slurry emanzi-bobunye ubugcisa. Ukusetyenziswa kwezandla kukhokelela kubukhulu obungahambelaniyo beqokobhe kunye namabala abuthathaka. Sisebenzisa ibhedi emanzi nkqu ne-stucco. Ndikhumbula iprojekthi kwangethuba apho sasinezinga lokungaphumeleli kwe-30% kwinqanaba le-valve yensimbi engenasici ngenxa yokungahambelani kwe-stuccoing manual. Ukutshintshela kwiinkqubo ezizisebenzelayo bekungekokusebenza nje kakuhle; yayimalunga nokuphelisa ukuguquguquka okusisiseko.
Ipateni yeWax: Apho Ulawulo LweDimensional eneneni Luqala khona
Wonke umntu ugxininisa kwisinyithi, kodwa ipateni ye-wax yinxalenye yokuqala. Ukuchaneka kwayo komphezulu kunye nokugqitywa komphezulu wokudluliselwa ngokuthe ngqo. Iiparamitha ze-injection ze-wax-ubushushu, uxinzelelo, ixesha lokubamba-lichazwe yinxalenye yejometri. Icandelo elinodonga olucekethekileyo lidinga izicwangciso ezahlukeneyo kune hub eshinyeneyo. Ukusebenzisa umdibaniso ongalunganga wewax (ewe, zininzi) kunokukhokelela ekucuthekeni kwemingxunya kwipateni ngokwayo, ethi emva koko ibe ziiblobhu eziphakanyisiweyo kumdlalo wokugqibela.
Sakhe saba nomxhasi ukuba asithumelele imodeli ye-CAD yeblade ye-injini entsonkothileyo. Iipateni ze-wax zeprototype ziphume kakuhle. Kodwa xa sifudukela kwimveliso, saqala ukubona i-warpage efihlakeleyo. Umoni? Iqondo lobushushu kwindawo yokusebenzela liye lenyuka ngamaxesha onyaka, litshintsha igophe lokupholisa lewax kwidayizi. Kwasinyanzela ukuba siphumeze amagumbi okutofa ngewax alawulwa yimozulu. Indawo 'yekhaya' ayinakwenzeka ukuba izinziswe kweli nqanaba, yiyo loo nto iziphumo zehobbyist ziguquguquka.
Ukudityaniswa kweepateni zewax 'emthini' lelinye inyathelo elibalulekileyo. Ii-engile kunye neejunction kufuneka ziyilwe ukuze zivumele ukuhamba kwesinyithi okufanelekileyo kunye nokunciphisa isiphithiphithi. Uyilo lokungena olulambathayo ngunobangela wokuqala we-porosity yangaphakathi engabonwa de kube machining. Senza ufaniso lokuqinisa ngoku kulo lonke uyilo olutsha, kodwa iminyaka ibilulingo kunye neempazamo-kwaye iimpazamo bezizimfumba ezibizayo zentsimbi elahliweyo.
Izinto eziphathekayo nguKumkani (kwaye zihlala zingaqondwa kakuhle)
'Intsimbi engenasici' asiyonto enye. I-304 i-stainless iziphatha ngokuhlukileyo ngokupheleleyo ekufakeni utyalo-mali kune-316 okanye i-17-4 PH. Le yokugqibela idinga unyango ubushushu isisombululo kunye nokuguga. Ukuba wenza ekhaya investment casting, kusenokwenzeka ukuba ubambekile nangasiphi na isilaphu onokuthi unyibilike, esinokwakheka okungaziwayo. Kwinxalenye yokwenyani, udinga izinto eziqinisekisiweyo. Sifumana ii-alloys zethu kwii-mills ezithile kwaye sizigcine zihlukanisiwe. Inkqubo yokunyibilika ilawulwa: i-deoxidizers, iqondo lokushisa elinyibilikayo, ixesha lokubamba. Ukugalela kushushu kakhulu kunokubangela ukukhula kweenkozo; kubanda kakhulu kunokubangela ukungavisisani.
Ukusebenza nge-alloys ezikhethekileyo ezifana ne-cobalt-based okanye i-nickel-based superalloys yenye yeligi. Zihlala zinyibilika kwaye zigalelwe ukuthintela i-oxidation. Awunakuyenza loo nto kwiziko elivulekileyo. Ezi zixhobo zeso sizathu le nto amashishini afana ne-aerospace kunye nezonyango zixhomekeke kwiziseko ezinendawo ezilawulwayo, hayi ukuseta igaraji. Iipropati zixhomekeke ngokupheleleyo kuloo nkqubo elawulwayo.
Unyango lobushushu emva kokuphoswa yinxalenye yohambo lwezinto. Asiyondlela yokuzikhethela 'yokugqiba ukubamba.' Ngamabakala amaninzi ensimbi kunye ne-alloy, ichaza iimpawu zokugqibela zomatshini. Ukuyitsiba okanye ukuyenza ngokungalunganga (indawo yobushushu engalunganga, ixesha lokufunxa, okanye ukucima okuphakathi) kukushiya unenxalenye enokuthi idlule kuhlolo olubonakalayo kodwa iya kusilela phantsi koxinzelelo. Sasineqela leengalo ze-lever kanye ezigqithise zonke iitshekhi ezinobungakanani kodwa zahluthwa ngexesha lokuhlanganisa. Ingxaki yalandwa emva kumjikelezo ophazamisekileyo we-austenitizing ngexesha lokunyanga ubushushu.
UMatshini we-CNC: Iqabane eliyimfuneko lokuCasa
Zimbalwa kakhulu iindawo zotyalo-mali 'eziyimilo yenetha.' Imiphezulu yokutywina ebalulekileyo, imingxuma yebholiti, kunye nojongano oluchanekileyo phantse lusoloko lufuna ukwenziwa ngoomatshini. Kulapho umanyano lubalulekile. E-QSY, ukuba ne-CNC machining endlini ayiyondlwan' iyanetha; yiluphu esemgangathweni. Oomatshini babuyisela ulwazi kwi-Foundry. Ukuba bahlala befumana indawo enzima okanye i-porosity kwindawo ethile yokuphosa, sinokuhlengahlengisa i-gating okanye iqondo lokushisa lokuthulula kweso ngundo.
Ukulungisa i-complex, as-cast geometry ngumngeni. Kufuneka umisele ii-datums ezithembekileyo ukusuka kwi-casting ngokwayo, ngamanye amaxesha kuthetha ukongeza iipads ezincinci okanye iimpawu kwipatheni ye-wax ngokukodwa kwindawo yokucoca. Olu luyilo lwentsebenziswano ukwenzela ukwenziwa. Ukuba ukuphosa kunye nomatshini kwenziwa kwiivenkile ezahlukeneyo, le loop yempendulo yaphukile, ekhokelela kwixesha elide lokukhokela kunye nokulahlwa okungakumbi.
Ndiza kukhomba iwebhusayithi yethu, tsngtaocnc.com, kungekhona ukukhuthazwa, kodwa njengomzekelo obambekayo wale synergy. Uluhlu lwesakhono apho-i-multi-axis milling, ukujika-ayahluki kumsebenzi wethu wokuphosa. Sesinye isiqingatha senkqubo. Inxalenye inokuba lutyalo-mali ukuze kufumaneke iipaseji ezintsonkothileyo zangaphakathi, emva koko i-CNC yenziwe ngomatshini ukuphumeza ubuso obuchanekileyo. Ukuzama ukufezekisa konke oko ngoomatshini kuphela kuya kuba kubiza kakhulu.
Ukujonga iNyaniso: Xa iKhaya lidibana nemizi-mveliso
Ke, ngaba unokwenza utyalo-mali lokwenyani ekhaya? Kwiiprototypes, iijometri ezilula, kunye neendawo ezingabalulekanga kwizinto ezaziwayo, mhlawumbi. Kodwa kukho iliwa olibethayo xa ufuna ukungaguquguquki, ukuqinisekiswa kwezinto eziphathekayo, kunye nokuthembeka koomatshini. Iziseko ezingundoqo-ulawulo lwemozulu, ulawulo oluludaka, inkxaso yelebhu yesinyithi, unyango olulawulwayo lobushushu-yinto oyihlawula ngokwenene ngesiseko sobuchwephesha.
Indlela eqhelekileyo yokusilela endiyibonayo kukujongela phantsi ipateni kunye nobunjineli beqokobhe. Abantu bagalela imali kwiziko elihle kodwa basebenzisa umthwebeba okumgangatho ophantsi kunye nodaka olusisiseko lokungunda. Isiphumo kukuphosa okujongeka kulungile kodwa kunokuncipha okufihlakeleyo okanye isikali somphezulu esenza ukuba singasebenziseki. Umngundo sisiseko.
Emva kweminyaka engamashumi amathathu kule ntsimi, isifundo sesokuba utyalo-mali luyikhonkco lekhulu lamakhonkco. Unokuba ne-wax enkulu, iqokobhe eligqibeleleyo, ukugalela okulawulwayo, kwaye uyonakalisa ngokuxutyushwa okungafanelekanga okanye unyango lobushushu. Yinkqubo efuna intlonipho kulo lonke ikhonkco. Umtsalane we ekhaya investment casting kuyaqondakala—ukutshintsha ukusuka kwiwax ukuya kwintsimbi kungumlingo. Kodwa uqeqesho olujika loo mlingo ube licandelo lobunjineli oluthembekileyo lwakhiwe phezu kokulawulwa, ngokufuthi okuqhelekileyo, ingqalelo kwiinkcukacha eziliwaka. Yiloo nto eyahlula iprojekthi yobugcisa kwilungu elibhabhayo, eliqhubayo, okanye eligcina inkqubo icinezelekile.
