Xa usiva 'utyalo-mali luphosa iinxalenye zemoto', umfanekiso ongoko nangoko ukholisa ukuba ngowaloo mavili antsonkothileyo, amenyezelayo e-turbocharger okanye izibiyeli ze-injini ezintsonkothileyo. Yinyani leyo, kodwa kulapho imbono engalunganga yeshishini iqala khona: ukucinga ukuba yenzelwe kuphela isiphelo esiphakamileyo, izinto ezingaqhelekanga. Ngokwenyani, inkqubo ifakwe ngokuzolileyo kwimveliso yobuninzi, kodwa imiceli mngeni itshintsha ngokupheleleyo. Ayikokwenza nje imilo; imalunga nokwenza ukuba iphile kwiimayile ezingama-200,000 zemijikelo ye-thermal kunye nokungcangcazela ngaphandle kokusilela, kwaye ukwenza oko ngeendleko ezingenzi ukuba umphathi wokuthenga aqhwebe. Ndizibonile iiprojekthi apho uyilo lwaluhle kwiscreen kodwa iphupha elibi kwisiseko, kunye nezinye apho uhlengahlengiso olulula kwi-engile eyidrafti lugcine intywenka yemali kumatshini. Makhe sithethe ngento efunekayo ngokwenene.
Isibheno esingundoqo: Kutheni i-Automotive ihlala ibuyela kuTyalo-mali lokuCasa
Ibilisa kwijometri kunye nokuthembeka kwezinto eziphathekayo. Kwiindawo ezifana utyalo-mali lokuphosa iinxalenye zeemoto njengezindlu zesivamvo ezinamatshaneli angaphakathi, okanye iinodi ezikhaphukhaphu zolwakhiwo lweefreyimu zebhetri ye-EV, awunakukwazi ukwenza okanye ukuzimatshini kwibhloko eqinileyo ngokwezoqoqosho. I-close-net-shape capability kukuphumelela kokuqala. Uyonga kwinkunkuma yezinto eziphathekayo, ngakumbi ngee-alloys ezibizayo, kwaye unciphisa iiyure zobuchwephesha besibini ngokumangalisayo.
Kodwa nantsi i-nuanced bits ethi ngamanye amaxesha iphoswe yi-specs: i-metallurgical consistency. Inxalenye elungileyo yotyalo-mali, xa inkqubo ifowunelwa, inokwakheka okufanayo, okucolekileyo. Oku kubalulekile kwiindawo eziphantsi koxinzelelo lwe-cyclic. Ndikhumbula iprojekthi yenjini yedizili ephuma ngeendlela ezininzi—nto leyo engaqhelekanga utyalo-mali lokuphosa iinxalenye zeemoto isicelo. Ucelomngeni yayingeyomilo; yayithintela iinyembezi ezishushu kumacandelo amancinci phakathi kwamachweba. Siye saphinda saphinda kathathu iresiphi yeqokobhe leceramic kwaye sahlengahlengisa iqondo lobushushu lokugalela ngama-25°C nje ukuze siqinise umphambili ekunene. Olo luhlobo lokulungiswa komgangatho wevenkile ongakubonisiyo iimodeli zeCAD.
Apha kulapho amaqabane esiseko sexesha elide abonisa ixabiso lawo. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi amathathu eminyaka kwiqokobhe kunye nokuphosa utyalo-mali, unaloo mava abhakiweyo. Bayibonile into esebenzela umzimba wevalvu yentsimbi ye-EGR echasene ne-nickel-based alloy turbine housing. Ulwazi oluthile lwezinto eziphathekayo-ukwazi ukuba, masithi, i-17-4PH i-stainless iya kuziphatha ngexesha lokususwa kweqokobhe-ayinakuthathelwa indawo. Ithintela ulingo kunye nempazamo ebiza imali eninzi kwidayimenti yakho.
INyaniso eyiGritty: Ukunyamezelana, imida, kunye neMachining Handshake
Akukho mntu kwikhonkco lokubonelela ngeemoto onobunewunewu bokuphosa ukugqiba izinto ezibalulekileyo. Isithembiso sokunyamezelana okuphoswayo sikholisa ukuba nethemba leendawo zokukhwelana. Inxalenye nganye ifuna i-datum, kwaye kulapho umatshini we-CNC ungena khona. Ubugcisa bokwenyani bukwisicwangciso senkqubo: ukwenza isigqibo sokuba yeyiphi imiphezulu ekuza kuphoswa kuyo kufutshane ne-net kunye nokushiya isitokhwe esingaphezulu ukuze sicoceke.
Ndifunde oku kabuhlungu kwangethuba ngesibiyeli sothumelo. Siyilwe ukuba ibeyi-net-shape eyimilo egqibeleleyo, sijolise ekupheliseni umatshini. Impazamo enkulu. Ukugqwethwa okuncinci kunyango lobushushu kuthetha ukuba iipateni zomngxuma webholithi zikhukuliseke ngokwaneleyo ukuze kubangele umba wokudibanisa kumgca wokuhlanganisa. Kwafuneka silahle yonke ibhetshi yokulinga. Ukulungiswa? Siye sayihlengahlengisa ukuze iphose owona mzimba uphambili ukuba ubume kodwa sashiya izibonelelo zomatshini onesisa kubo bonke ubuso obubalulekileyo. Ixabiso lenxalenye nganye liye lehla ngenxa yokuba isivuno siye sanyuka. Le ndlela idityanisiweyo yiyo kanye kutheni imisebenzi edibanisa ukuphosa kunye nomatshini phantsi kophahla olunye, njengoko i-QSY yenza kunye nabo utyalo mali kunye namasebe e-CNC, abe nokuhamba kakuhle komsebenzi. Oomatshini bathetha nabafana base-Foundry yonke imihla; bayayazi indlela enokuthi ijike ngayo inxalenye kwaye banokucwangcisa ukulungiswa ngokufanelekileyo.
Ukugqitywa komphezulu lelinye ibala lokulwa. Umphezulu otyhidiweyo unokubukeka ulungile, kodwa inxalenye ebona uxinzelelo lwe-oyile okanye ene-O-ring groove, i-as-cast porosity ingaba yindlela yokuvuza. Sihlala sicacisa ukugqiba komatshini kwindawo yokutywina, nokuba yongeza inyathelo. Undoqo kukunxibelelana oku ngokucacileyo kwi-stack-up yomzobo. Ngaba loo Ra 3.2 μm iyimfuneko yonke inxalenye, okanye nje ubuso flange? Ukungacaci kakuhle apha kubiza imali kunye nexesha.
Ukukhetha izinto eziphathekayo: Akunjalo nje malunga namandla
Hamba kuyo nayiphi na intlanganiso yobunjineli beemoto, kwaye ingxoxo yezinto eziphathekayo ilawulwa ngamandla okuqina kunye namanqaku esivuno. Kuba utyalo-mali lokuphosa iinxalenye zeemoto, litikiti nje lokungena. Kuya kufuneka ucinge malunga ne-castability, weldability (yee-sub-assemblies), kunye ne-machinability ezantsi komsinga.
Thatha inyathelo uye kwicala elingaphezulu lokukhupha kwintsimbi engatyiwayo ukuze uxhathise umhlwa. I-AISI 316 ilungile ku-corrosion, kodwa i-gummy kumatshini. Ukutshintshela kwibakala elinokusetyenzwa ngakumbi elifana ne-303, okanye ukwahluka kobunikazi basimahla kwisiseko, kunokonakalisa ukunxitywa kwesixhobo se-CNC kunye namaxesha okujikeleza. Iqabane elifana ne-QSY, edwelisa ubuchwephesha kwii-alloys ezingenasici kunye nezikhethekileyo ezifana ne-cobalt kunye ne-nickel-based based, inokucebisa ngolu rhwebo. Banokuthi bacebise, umzekelo, inguqu yekhabhoni ephantsi yebakala lensimbi ukuba inxalenye iya kuxutywa kamva, ukukhusela imvula ye-carbide kwindawo echaphazelekayo ukushisa.
Emva koko kukho i-coefficient yokwandisa i-thermal. Kwindibano edibanisa indlu ye-aluminium kunye nentsimbi yokufaka i-cast-in-place, udinga ii-alloys ezidlala kakuhle nge-thermal. Ukufumana oko kungalunganga kukhokelela kuxinzelelo olushiyekileyo kunye nokusilela kokudinwa kwangaphambi kwexesha. Kolu khetho lwemathiriyeli luphakathi kwezifundo olwahlula iprototype esebenzayo ukusuka kwimveliso esele ilungile, icandelo elihlala ixesha elide.
Iindlela zokungaphumeleli kunye neZifundo abazifundisayo
Awuyiqondi nyani inkqubo yokuvelisa de uyibone isilela. Enye inkumbulo ecacileyo yibhetshi yemizimba ye-aluminiyam. Baphumelele zonke iitshekhi ezilinganayo kodwa abaphumelelanga kuvavanyo loxinzelelo kwindawo yenjini. Umoni? I-Micro-shrinkage porosity kumacandelo ashinyeneyo kufutshane ne-lugs ekhwelayo, engabonakaliyo kwi-X-reyi kwisampulu yethu rhoqo. I-Foundry kwafuneka iguqule inkqubo yokungena ukuze yondle ngcono ezo ndawo ngexesha lokuqina. Ibiyimeko eqhelekileyo yokuyilwa komsebenzi kodwa hayi ukwenzeka.
Omnye umgibe oqhelekileyo kukujongela phantsi iindleko zokuntsonkotha. Ukongeza into enye yangaphakathi eyongezelelweyo inokubonakala ngathi isimahla kuyilo, kodwa ukuba ifuna isiseko seceramic entsonkothileyo kwaye inesantya esiphezulu sokuqhekeka ngexesha lokususwa kwegobolondo, ixabiso leyunithi yakho inokuphinda kabini. Ndikhe ndahlala neenjineli zenkqubo apho silinganise ngokwenyani iindleko zokongeza undoqo xa kuthelekiswa nokugrumba inqaku kumsebenzi wesibini we-CNC. Ngamanye amaxesha, ukwenza oomatshini kutshiphu. Injongo ye utyalo mali ayikokuphelisa bonke oomatshini; kukwandisa ixabiso lilonke lenxalenye egqityiweyo, eqinisekisiweyo.
La mava agxininisa ukuba kutheni inkqubo yolawulo lomgangatho yomthengisi ingaxoxiswana. Akunjalo malunga nokuhlolwa kokugqibela. Imalunga nolawulo lwenkqubo kwinqanaba ngalinye: ukuhambelana kwenaliti yewax, i-ceramic slurry viscosity, iiparamitha zokuthoba, ikhemikhali yokunyibilika kwesinyithi, kunye namagophe onyango lobushushu. Inkqubo eyomeleleyo ibamba ukunxaxha phambi kokuba ibe sisilaphu. Xa ndivavanya umthombo, ndihlala ndibuza malunga nolawulo lwenkqubo yezibalo (SPC) kwimilinganiselo ebalulekileyo kunye nobunzulu bengxelo yabo yokuhlola inqaku lokuqala.
Ikamva: Ukukhanya, ukuFakwa koMbane, kunye neNkqubo yeNdalo
Ukuqhuba izithuthi zombane utshintsha i utyalo-mali lokuphosa iinxalenye zeemoto imbonakalo-mhlaba. Amalungu ahlukile: iipleyiti zokupholisa ezintsonkothileyo zeepakethi zebhetri, i-aluminiyam ekhaphukhaphu okanye izakhi ze-magnesium, kunye nezibiyeli eziphakamileyo zokunyuswa kweemoto zombane. Imithamo iphezulu, nto leyo ityhala inkqubo ekuzitshintsheni ngakumbi kwi-wax edityanisiweyo kunye nokwakhiwa kweqokobhe ukugcina ukungaguquguquki kunye neendleko ekujoliswe kuzo.
Kukwakho umsebenzi onomdla kwiinkqubo zemixube. Umzekelo, ukuphosa i-manifold entsonkothileyo kwintsimbi engenastainless kodwa ishiya iipads ezicwangcisiweyo zokwenziwa komatshini kamva wamazibuko oluvo. Okanye usebenzisa ushicilelo lwe-3D ukwenza iimolds ze-ceramic ezithe ngqo ze-ultra-complex prototype part, ukugqithisa i-wax ye-pattern yesiqhelo yesixhobo ngokupheleleyo kwimiba emfutshane. Kulapho ishishini lisingise khona—ukudibanisa ubuchwephesha obudala kunye nobutsha.
Ekugqibeleni, impumelelo kweli candelo ayithethi ukuba neyona ncwadana iqaqambileyo. Kumalunga nokuba nobunzulu bamava ukukhangela ukulungelelana phakathi kwenjongo yoyilo, ifiziksi yezinto eziphathekayo, kunye noqoqosho lwemveliso. Imalunga namahlakani anokuthi ajonge umzobo kwaye ngoko nangoko afake iflegi yeendawo ezinokubakhona ezishushu, acebise iradiyasi yefillet elungele ukuphosa, okanye acebise ibakala lemathiriyeli eliya kwenza ngcono enkonzweni. Olo lusebenzayo, intsebenziswano yokusombulula iingxaki yinto ejika uyilo olulungileyo lube yinto ethembekileyo, enexabiso eliphantsi leemoto eziqengqeleka emgceni, unyaka nonyaka. Lelona xabiso lokwenyani lenkqubo, engaphaya kwamandla ayo ukwenza iimilo ezintle.
