Uva 'ukwenziwa kwentsimbi echanekileyo' kwaye ngoko nangoko ucinge ngonyamezelo oluqinileyo, umphezulu ongenasiphako, mhlawumbi izinto ze-aerospace. Leyo yinqanaba lentengiso. Inyani kumgangatho wesiseko luthethathethwano oluqhubekayo phakathi kwejometri efanelekileyo kwimodeli yeCAD kunye nefiziksi enenkani yesinyithi esinyibilikisiweyo. Ukuchaneka kokwenyani akukho nje kumlinganiselo; kukuqikelela ukuba intsimbi ye-316L okanye i-alloy ephantsi iya kuziphatha njani ukusuka xa ishiya i-ladle ide iphole kwi-shakeout. Baninzi kakhulu abafana abathengayo abalungisayo kwingxelo yokugqibela yomlinganiselo, baphose yonke inkqubo yobunjineli eyenza ukuba loo ngxelo ibekho. Kulapho iindleko zokwenyani kunye nexabiso lilele khona.
Umdlalo weShell: Ngakumbi kuneMngundo nje
Uninzi lunxulumanisa ukuchaneka kunye nokuphosa utyalo-mali, inkqubo ye-wax elahlekileyo. Igqwesile, kodwa kuluhlu lwamacandelo entsimbi, ngakumbi ezo zinobunzima obuphakathi kunye neemfuno zevolumu ephezulu, ukubunjwa kweqokobhe lelona gama lingenamsebenzi. Kwiivenkile ezifana neQingdao Qiangsenyuan Technology Co., Ltd. (QSY), apho bebehleli khona ngaphezulu kweminyaka engamashumi amathathu, ubona ukuba ukhetho alukho ngqiqweni. Iyasebenza. Ukubumba iqokobhe, kusetyenziswa isanti eqatywe intlaka, kukunika ibhalansi emnandi. Ukuqina komngundo kulawula ukugqwetheka ngcono kunokuba uninzi lulindele, kwaye ukugqiba komphezulu kunokubetha iRa 12.5 μm okanye ngcono ukuba ulawula iiparamitha zakho. Ayisoloko imalunga neyona nto igqibeleleyo, kodwa malunga neyona nkqubo inamandla nephindaphindwayo yomsebenzi wenxalenye.
Isitshixo sikwipatheni. Ipateni yentsimbi ephezulu, elungiselelwe ukugqibelela, yindawo yokuqala engenakuxoxisana. Nasiphi na isiphene apha siphindaphindwa ngokukhawuleza. Ndibone iiprojekthi zisilela kuba umntu uzame ukonga kwiindleko zepateni. Ubungqingqwa beqokobhe abufani—bolekwe ngokobuchule. Amacandelo atyebileyo apho umothuko we-thermal uya kuba phezulu ngexesha lokugalelwa. Olo hlobo lweenkcukacha luvela kumava afakiweyo, hayi nje incwadi yesikhokelo. Ufunda 'ukufunda' iqokobhe emva kokukhutshwa kwewaxing, ujonge iintanda ezifihlakeleyo okanye amabala athambileyo abonisa ukukhuhla kwexesha elizayo okanye ukungena kwentsimbi.
Apho ikhohlisayo kukusebenzisa iziteshi zangaphakathi okanye ii-cores. Kwintsimbi, udibaniso olungundoqo kubumba lweqokobhe lufuna ukubamba ugqirha. Ukungahambi kakuhle ngesiqingatha semilimitha kunokuguqula indlela yokupholisa ibe yinto engenamsebenzi. Indlela ye-QSY yokudibanisa i-CNC machining post-casting ihlala igcina ezi ndawo. Bangakwazi umatshini kwindawo yokuphosa, ukulungisa utshintsho oluncinci olungundoqo, kodwa uyilo kufuneka luvumele oko. Yincoko ekufuneka yenzeke phambi kokuba ipateni yokuqala isikwe: Singakwazi phi ukushiya isitokhwe esongezelelweyo ukuze sifumane ipasi yokucoca? Leyo yingcinga edibeneyo yokuvelisa.
Isixhobo sisiguquguquko esithe cwaka
Intsimbi ayikho nje intsimbi. Ukugalela intsimbi yekhabhoni ngokuchasene ne-nickel-based alloy efana ne-Inconel 718 yindalo eyahlukileyo. Ukuchaneka kokusalwa kuxhomekeke ngokupheleleyo kukuziphatha kokuqina kwemathiriyeli. Izinto zokucutheka azikho mgca. Ingalo ye-lever elula kwi-CF8M engenastainless inokufuna isikhuphukeli sokutya kabini ubunzima benxalenye ngokwayo ukunqanda ukushwabana kwe-porosity kwi-hub. Awuyiqikelela le nto; uyayifunda ngokusika kunye nokuhlola amakhulu eeprototypes zedini.
Kulapho imvelaphi yeminyaka engama-30 yesiseko ibalulekile. Bakhe ithala leencwadi zengqondo, uhlobo lolwazi olucekethekileyo. Bayazi ukuba ibakala elithile le-duplex stainless lithanda 'ukutsalwa' ngakumbi kwiikona ezibukhali zokungena kwakhona, zifuna iradiyasi enkulu yefillet kunokuba umyili anokufuna. Baza kubuyisela umva kumzobo, kungabi nzima, kodwa kuba besazi ukuba ukusukela iradiyasi engafanelekanga njenge-cast-cast kuya kukhokelela ekukrazuleni okushushu, ukukrazula indawo. Ukuchaneka kufezekiswa ngamanye amaxesha ngokungaphosi emphethweni wento enokwenzeka ngokwethiyori.
I-alloys ezikhethekileyo, njenge-cobalt okanye i-nickel-based based based portfolio ye-QSY, yongeza enye ingqimba. Ukumanzi kwazo kwahlukile, zihlala zigalelwa kumaqondo obushushu aphezulu, kwaye zisabela ngakumbi kumoya wokungunda. Inkqubo yakho yokungena kunye neyokuphuma umoya iba yimfuneko. Isikhunta esingangeni kakuhle siya kubangela isiphithiphithi, ukubamba irhasi kunye nokudala iziphene zomhlaba ekungekho bungakanani bomatshini obunokulungisa ngokupheleleyo. Ukuchaneka kulahlekile phambi kokuba isinyithi sizalise ngokupheleleyo umngxuma.
I-CNC Handshake: Apho ukuCasa kuhlangana khona neSiqiniseko
Akukho msebenzi wokujula wentsimbi ochaneke kakhulu uyema ekushukumeni. Imo ye-as-cast yifomu yangaphambili. Imilinganiselo eqinisekisiweyo ivela kumatshini weCNC. Eli likhonkco elibalulekileyo. Isiseko esinomatshini wangaphakathi, njengale nto ubona kuyo tsngtaocnc.com, inenzuzo enkulu. Oomatshini kunye neenjineli zabasunguli bathetha ulwimi olufanayo. Babelana ngomgangatho omnye.
Utyando lokuqala luhlala luseka idatham. Uyilungisa njani icast ekrwada yiyo yonke into. Kufuneka ufumane indawo ezinzile kwaye imele ijiyometri esebenzayo yecandelo. Ngamanye amaxesha, singade siphose amancinci, amadini eephedi kubuso obungabalulekanga nje ukuba sibe nococeko, umphezulu ocatshangelwayo we-vise grip yokuqala. Yinkcukacha ethobekileyo, kodwa iqinisekisa ukuba bonke oomatshini abalandelayo babhekiswa ngokuchanekileyo, ukutshixa ukugajwa kwentsimbi echanekileyo's amandla.
Ndikhumbula umzimba wevalve yehydraulic, intsimbi ephantsi kwealloyi. I-as-cast bore yayingaphakathi kwe-1mm yobukhulu bokugqiba, kodwa eyona ndawo yokwenyani yokudibana kwezibuko yayingumceli mngeni. Ngokwenza oomatshini be-CNC endlini, banokuphonononga indawo ephosiweyo, bahlengahlengise ulungelelwaniso lomatshini ngomzuzu ukuze babuyekeze ukwahluka kwesiseko, kwaye babethe imeko eyinyani yokufowuna kushicilelo. Oku akulungiseleli ukuphosa okubi; ibuyekeza ngokwendalo, ukwahluka okuvumelekileyo kwenkqubo yokuphosa ukuze kuphunyezwe iziphumo ezichanekileyo. Yimbono epheleleyo yokwenziwa kwemveliso.
Iintsilelo Zezona Iincwadi Zezifundo
Ufunda ngakumbi kwibhetshi ekhutshiweyo kunewaka lamalungu agqibeleleyo. Kwangoko, saba nokuqhutywa kwezindlu zempompo kwi-CA15 martensitic stainless. Imilinganiselo yayimihle, umphezulu wawucocekile. Uphumelele uhlolo lokuqala. Kodwa kuvavanyo loxinzelelo, siye savuza kudonga olubonakala luqinile. Yinqumle, kwaye kwakukho inethiwekhi yeenwele ze-micro-shrinkage, engabonakaliyo ngaphandle. Umoni? Iqondo lobushushu lokugalela laliphezulu kakhulu, lileqa ulwelo olungcono lokuzalisa amanye amacandelo amancinci, kodwa lwatshintsha ukulandelelana kokuqina. Sizipholise ukugalela, sathoba isantya, kwaye songeza into encinci, epholileyo yendawo kolodonga lwengxaki. Ingxaki isonjululwe. I-spec sheet ithi nje i-CA15, i-ASTM A743. Khange ithethe ukuba mayigalelwe njani.
Olunye ukusilela kweklasiki kukuyila ngaphezulu kokuchaneka. Umxhasi wake wafuna umphezulu ongasebenziyo wangaphakathi ukuba uphoswe kwi-Ra 6.3 μm ekugqibeleni kunye nokunyamezelana kwe-± 0.1mm. Yayibiza kakhulu ngokweenkwenkwezi. Saye saxoxisana ngokuyilungisa, kodwa basinyanzelela. Izinga lesivuno lalibi kakhulu, mhlawumbi ngama-30%. Ekugqibeleni, emva kokugqithiswa kweendleko, bavuma ukusivumela ukuba siyiphose ngokurhabaxa size siyimatshini. Iindleko zehle nge-60%, kwaye isivuno sadubula ukuya kuma-98%. Isifundo: Ukuchaneka kokwenyani kukusebenzisa inkqubo eyiyo kwimfuno eyiyo. Ayizizo zonke iindawo eziku a ukugajwa kwentsimbi echanekileyo kufuneka ifakwe ngokuchanekileyo.
I-Pragmatic Supply Chain: Imalunga nokuZinzo
Xa ukhupha ukuhanjiswa okuchanekileyo, ngakumbi kwiqabane elinje nge-QSY, awuthengi nje icandelo. Uthenga ileja yolawulo lwenkqubo. Ukuhambelana ngaphaya kwe-500-part order kubaluleke kakhulu kunomfezeko opheleleyo wesampuli enye. Ngaba banokubamba umphezulu ofanayo ogqityiweyo kwinqanaba loku-1 kunye necandelo lama-500? Ngaba ingxelo yabo ye-metallurgical ibonisa ibhetshi yekhemistri efanayo emva kwebhetshi?
Oku kuxhomekeke kwizinto eziqhelekileyo. Iinkqubo zokubuyiselwa kwesanti. Izigodo zobushushu kubo bonke ubushushu. Iishedyuli zolungelelwaniso lwee-spectrometers. I-website ye-Foundry inokudwelisa zonke i-alloys ezisehlabathini, kodwa ubungqina bukwinkqubo yamaxwebhu abanokubonelela ngayo. Eyona nto iqinisekisayo umthengisi angakubonisa ukuba awuyosampuli emenyezelayo; yitshathi yokulawula inkqubo egugileyo, ehlala izaliswe.
Ekugqibeleni, ukuphoswa kwentsimbi echanekileyo yibhulorho phakathi kwenjongo yoyilo kunye nenyani ebonakalayo. Ayingomlingo. Luqeqesho olubi, lobugcisa, kunye namava anzulu apho impumelelo ilinganiswa kwizivuno eziphindaphindwayo kunye nokuzithemba okuthe cwaka ukuba inxalenye ephuma kwibhokisi yokuthunyelwa iya kusebenza, ngalo lonke ixesha. Iinkampani ezihlala, ezinamashumi eminyaka phantsi kwebhanti yazo, ziyaqonda ukuba ukuchaneka kukwinkqubo, kungekhona nje ngexesha lokuthulula.
