Xa abantu abaninzi besiva 'intsimbi engenastainless steel lost wax casting', baba nomfanekiso welungu elingenasiphako, elimenyezelayo eliphuma ngqo kwincwadana. Leyo yimbono yokuqala ephosakeleyo. Inyani imbi kakhulu, incanukene ngakumbi, kwaye ibandakanya ukusonjululwa kwengxaki kangangoko isenza. Ayikokwenza nje imilo; imalunga nokulawula ikhulu leenguqu ukuze ufumane indawo esebenzayo edibana ne-spec sheet egcwele amanani-amandla okuqina, ukuxhathisa umhlwa kwindawo ethile, imilinganiselo yoxinzelelo. Indawo 'engenastainless' iphantse ibe yi herring ebomvu; Ibakala libaluleke ngaphezu kosapho. I-304, i-316, i-17-4PH-nganye iziphatha ngendlela eyahlukileyo xa uyithululela kwi-1500 ° C kwi-shell shell. Kulapho umsebenzi wokwenyani uqala khona.
Umdlalo weShell: Konke KukuMngundo
Masithethe ngeqokobhe. Le asiyongundo nje yodaka. Sisixhobo se-ceramic esinemigangatho emininzi esakhiwe ngokudipha iipateni zewax kwi-slurries kunye ne-stuccos. Inani leedyasi, ixesha lokumisa phakathi kwendawo nganye, ukufuma kwe-ambient-fumana enye engalunganga kwaye iqokobhe liyaqhekeka ngexesha le-dewaxing (imbonakalo emangalisayo, ukusilela okumdaka) okanye alomelelanga ngokwaneleyo ukuba liqulathe isinyithi esinyibilikisiweyo, esikhokelela kwinto esiyibiza ngokuba 'kukuphelelwa'. Ndibone umthi ogqibeleleyo we-wax wendlu yempompo wonakalisiwe kuba idyasi yesithathu yoma ngokukhawuleza kwiveki eyomileyo. Iqokobhe lalikhangeleka lilungile, kodwa lineentanda ezincinci. Ngexesha lokugalela, kwakufana nesefu. Ilahleko iyonke.
Oku kulapho amava avela kwivenkile efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) imiboniso. Ngaphezu kweminyaka engama-30 ubudala utyalo mali, baye babhaka olu lwazi lwenkqubo kwinkqubo yabo. Ayikho kwincwadi yemigaqo; kukuziva kwegcisa lendlela oluthontsiza ngayo uludaka, inkangeleko yeqokobhe elomileyo. Iwebhusayithi yabo, tsngtaocnc.com, idwelisa ukubunjwa kweqokobhe njengondoqo ongundoqo ngesizathu. Linyathelo elisisiseko. Unokuba neyona ngxubevange igqwesileyo, kodwa ukuba iqokobhe lakho liyasilela, ugalela nje intsimbi ebizayo emgangathweni.
Inkqubo yokukhutshwa kwewaxing ngokwayo ibalulekile. Abaninzi bacinga ukuba unyibilikisa i-wax. Uninzi lweevenkile ezinomthamo ophezulu zisebenzisa i-autoclaves okanye i-flash dewaxing ene-high-pressure steam. Umothuko we-thermal kwiqokobhe mkhulu kakhulu. Ukuba inkqubo yeqokobhe ayihambelani ngokugqibeleleyo neli nyathelo, iya kwaphuka. Oku sikufunde kwangethuba ngendlela entsonkothileyo, enodonga olucekethekileyo. Ukutshintshela kwisixhobo esahlukileyo esichasayo kwidyasi yokuqala, ingxaki isonjululwe. Ngolu hlengahlengiso luncinci, lwenqanaba lemathiriyeli olwahlula indawo enokusebenziseka kwi-scrap.
Ukuxhalaba kweBanga: Ukukhetha i-Right Stainless
Ukuchaza intsimbi engatyiwayo kufana nokungena kwivenkile yehardware uze ucele isixhobo. Ayinantsingiselo ngaphandle komxholo. Kwizixhobo zaselwandle, i-316 yinto engagqibekanga yokumelana nokuthotywa kwe-molybdenum. Kodwa ndiye ndanabaxumi banyanzelisa i-316 yangaphakathi, isicelo esomileyo apho i-304 yayiya kuba yanele kwaye inexabiso eliphantsi. Kufuneka uhlehle umva, ufundise.
Emva koko kukho amabakala okuqina kwemvula njenge-17-4PH. Okumangalisayo kumandla aphezulu, anzima intsimbi engenasiphene elahlekileyo iindawo zokugalela umthwebeba njengezibiyeli ze-aerospace. Kodwa umjikelo wonyango lobushushu emva kokuphosa awuxoleli kwaphela. Izidanga ezimbalwa kwiqondo lobushushu lokuguga, kwaye awufumani ubulukhuni beRC obufunekayo. Inxalenye ibonakala ifana kodwa iya kusilela kuvavanyo. Ukukhankanywa kwe-QSY yokusebenza ngeealloyi ezikhethekileyo ezifana neze-nickel-based zindixelela ukuba bayayifumana le. Ezo zixhobo zinomsindo ngakumbi. Inkqubo yokuphosa nje sisiqingatha sokuqala sohambo; iprotocol ye-thermal yeyesibini.
Ndikhumbula ibhetshi yemizimba yevalvu kwi-CF8M (i-cast elingana nama-316). Baphumelele zonke iitshekhi ezinobungakanani kodwa basilela kuvavanyo olubalulekileyo lokutya umrhwaphilizo kumxhasi kwishishini lemichiza. Ingxaki? Umxholo we-Delta ferrite. Izinga lokupholisa kwiqokobhe lalicimile kancinci, liguqula i-microstructure. Kwafuneka silungise iqondo lobushushu lokugalela kwaye siguqule iipropathi zeqokobhe le-insulating-songeza umaleko owongezelelweyo we-ceramic fiber ejikeleze amacandelo anzima-ukucothisa ukupholisa. Ingxaki ilungisiwe, kodwa yathatha uhlalutyo lwe-metallurgical ukufumana unobangela. Inxalenye yayikhangeleka igqibelele kwiliso lenyama.
I-Dimensional Tightrope: As-Cast vs. Machined
Enye yezona ndawo zithengisa kakhulu ze-wax elahlekileyo kukubunjwa kwe-net-shape shape. Igama elingundoqo 'kufuphi.' Nabani na othembisa ± 0.1mm ukunyamezela kuyo yonke imiphezulu yenxalenye ye-as-cast uyasolula inyaniso. Kufuneka ulawule okulindelekileyo. Ukucutheka kuyaqikelelwa kodwa akufani ngokugqibeleleyo. Inqaku elide, elibhityileyo liya kucutheka ngokwahlukileyo kunebloko enkulu ekubunjweni okufanayo. Ipatheni iyafa ngenxa yoku, kodwa kuhlala kukho umahluko.
Yingakho imodeli yenkonzo epheleleyo yeenkampani ezidibanisa ukuphosa kunye CNC Machining yenza ingqiqo kakhulu. Kwi-QSY, badwelisa zombini njengeenkonzo eziphambili. Uphosa indawo ukuze ufumane ijiyometri entsonkothileyo engama-90% apho, kunye nesitokhwe esinesisa kwindawo ebalulekileyo yokukhwelana, imisonto, kunye nobuso bokutywina. Emva koko, uyilungisa kwi-CNC mill okanye i-lathe kwaye ubethe imilinganiselo echanekileyo. Ukuzama ukufezekisa oko kunyamezelwa ngokuthe ngqo kwi-mold yinkqubo yesidenge kwaye ibiza kakhulu malunga nezixhobo kunye nelahleko yesivuno.
Sakhe sazama ukuphosa igiya enamazinyo asebenzayo, njenga-aphoswe ngamazinyo ukonga kwiindleko zoomatshini. Iprototype yayilungile, kodwa kwimveliso, ukwahluka okongezelekayo kwiprofayile yezinyo kuninzi lwamalungu akwamkelekanga. Sifunda ntoni? Yazi imida yenkqubo. Lahla igiya blank, matshini amazinyo. Intsebenziswano phakathi kwezi nkqubo zimbini—utyalo mali ngenxa yobunzima, i-CNC yokuchaneka-kulapho ixabiso lokwenene lenzelwe injineli.
Abaqhubi Beendleko Ezifihlakeleyo: Ukugada, Ukuvelisa, kunye nokugqiba
Ukucaphula inxalenye ye-wax elahlekileyo ayikho nje malunga nobunzima. I-1kg egqityiweyo inxalenye inokuqala njengomthi we-wax we-3kg. Isango lokungena kunye nenkqubo yembaleki, ehambisa intsimbi, inkulu kwaye iyanqunyulwa kwaye isetyenziswe kwakhona. Isivuno sakho (inxalenye yobunzima obugqityiweyo vs. ubunzima bentsimbi egalelwe) yindleko enkulu. Uyilo olusebenzayo lokungena, oluhlala lufaniswa nesoftware ngoku, lubalulekile. Isango eliyilwe kakubi linokubangela isiphithiphithi, ukuvalelwa komoya, kunye ne-shrinkage porosity ngqo kwicandelo elibalulekileyo lenxalenye yakho.
Emva koko kukho ukugqiba. Emva kokuvuthulula kunye nokunqunyulwa, unenxalenye egqunywe kwiintsalela zeqokobhe leceramic kunye neengcango zamasango arhabaxa. Ifuna ukudutyulwa, ukucolwa, mhlawumbi ukucocwa kweekhemikhali (i-pickling kunye ne-passivation ye-stainless ukubuyisela umaleko we-oxide onganyangekiyo). Oku kufuna umsebenzi onzima kwaye kuhlala kungahoywa kwisicwangciso sokuqala. Icandelo elineepaseji ezininzi zangaphakathi liphupha elibi lokucoca. Ndichithe iiyure ndikhetha amazinyo kunye neejethi zamanzi ezinoxinzelelo oluphezulu ndizama ukususa i-ceramic edibeneyo kwisitishi sokupholisa. Ngoku, siyila ukucoceka kwasekuqaleni.
Lo msebenzi wesigaba sokugqibela kulapho ubuninzi bobugcisa buhlala khona. Iirobhothi zokusila ezizenzekelayo zilungile kwiimilo eziqhelekileyo, kodwa i-valve yezindlu ezintsonkothileyo? Oko kudla ngokufuna isixhobo sokusila esinesakhono esinesandla esizinzileyo ukudibanisa imiphezulu ngaphandle kokugrumba isiseko sesinyithi. Bubugcisa.
Xa Ihamba Ngokufanelekileyo: Intlawulo
Nangona iintloko ezibuhlungu, xa ubambe ogqibeleleyo, onzima intsimbi engenasici elahlekileyo yokugalela iwax inxalenye-uthi, i-impeller yesiqwenga esinye se-injini eneencakuba ezigobileyo ezinokuthi akunakwenzeka ukwenza umatshini ukusuka kokuqinileyo-kuyafaneleka. Ingqibelelo yenxalenye engenazo ii-welds okanye ii-joints, ukukwazi ukusebenzisa i-alloys ephezulu yokusebenza kwiifom ezintsonkothileyo, ukugqiba umgangatho obalaseleyo odla ngokufuna ukulungiswa okuncinci kokwaleka.
Yinkqubo efuna intlonipho kulo lonke ikhonkco, ukusuka kwinaliti yewax ukuya ekuhlolweni kokugqibela. Awukwazi nje ukuba yi-metallurgist okanye i-Foundry guy okanye i-machinist. Kufuneka uqonde ukuba inqanaba ngalinye lithetha njani nelandelayo. Leyo yimvakalelo endiyifumanayo kwimisebenzi efana nale ichazwe kuyo tsngtaocnc.com. Ukuhlala kwabo ixesha elide kucebisa ukuba bajonge le miceli mngeni idityanisiweyo kwimathiriyeli ukusuka kwintsimbi etyhidiweyo ukuya kwi-nickel alloys. Ubuchule bokwenyani adweliswanga njengenkonzo; yiminxeba eqokelelweyo yomgwebo eyenziwe kumawakawaka okuthululwa, kugqibezela indlela yokulungisa inkqubo yelandelayo.
Ke kwixesha elizayo xa uphonononga ukubunjwa, jonga ngaphaya kokukhanya. Cinga ngeqokobhe elilibambileyo, indlela yokufudumala efunekayo ukuze liqine, isitokhwe esisele sishiywe ukuze kwenziwe oomatshini, nomsebenzi wezandla owalicocayo. Nantso ibali lokwenyani inxalenye. Okunye kukuthengisa nje.
