Xa iinjineli zicacisa ukuphoswa komxhuzulane kwiindawo zetsimbi eziphezulu-ingakumbi kwiinkqubo ze-hydraulic, i-oyile & i-valve yegesi, okanye i-heavy-duty pump housings-ayikhethi nje inkqubo. Bakhetha iqabane elilawula ukuhambelana kwe-metallurgical, ukuphindaphinda kobukhulu, kunye nokuthembeka kokusebenza ukusuka kwi-alloy eluhlaza ukuya kwindawo egqityiweyo. Yiyo loo nto amaqela okuthengwa kwempahla yehlabathi esiya eguqukela kwiingcali umzi-mveliso wokuphosa umxhuzulane imisebenzi-hayi iziseko eziqhelekileyo-ezinamandla adityanisiweyo ngokuthe nkqo, ukulandeleka okubhaliweyo, kunye namava angqiniweyo kwii-superalloys ezifana ne-AMS 5387 kunye ne-T800.
Kutheni iGravity Casting isaphumelela kwiMishini-Amacandelo abalulekileyo kuShishino
Ukuphosa umxhuzulane akukudalanga. Kukhethwe ngamabom xa ufuna i-dense, i-low-porosity castings kunye nolawulo oluqinileyo lwepropathi yomatshini-ingakumbi kwiindawo ezifumana imithwalo yoxinzelelo lwe-cyclic okanye ukunxitywa kwe-abrasive. Ngokungafaniyo ne-high-pressure die casting, isinyithi esinyibilikisiweyo esityhidiweyo ngumxhuzulane singena kubumba ngokucothayo, sinciphisa isiphithiphithi kunye nokubanjwa kwegesi. Isiphumo? Amandla aphezulu okuqina, ukumelana nokudinwa okungcono, kunye nokusebenza okuphezulu kwe-post-cast-okubaluleke kakhulu kumacandelo afana nezindlu ze-piston pump cylinder okanye imizimba yevalve yoxinzelelo apho i-micro-shrinkage okanye i-voids yangaphakathi inokubangela ukusilela kwintsimi.
Siye sabona abathengi betshintshela kwezinye iindlela zotyalo-mali emva kokuqhekeka ngokuphindaphindiweyo kwimilomo ye-cobalt-nickel esebenza ngaphezulu kwe-450 ° C. Ukuphosa umxhuzulane kuhambise ubume obufunekayo bezinto eziziinkozo-kwaye ngokubalulekileyo, kwavumela ukubekwa okuchanekileyo kwezinyusi kunye nezixhasi ukuqinisekisa ukuqina kwecala. Loo nqanaba lolawulo lwenkqubo alwenzeki ngengozi. Ifuna ingqiqo yesinyithi enzulu, amashumi eminyaka yepateni ukuya kwinxalenye yeelophu, kunye ne-ISO-ethobelayo yokuhlola i-thermal kuyo yonke into egalelwayo.
Izakhono ezine eziNgaxoxisaniyo kwiFactory yokuCasa iGravity eSebenza ngokuPhezulu
Umntu okwaziyo umzi-mveliso wokuphosa umxhuzulane kufuneka ahambise ngaphezu kwentsimbi egalelwe nje. Nantsi into eyahlula amaqabane alungele imveliso kubaboneleli bentengiselwano:
- Ubuchule bezinto eziphathekayo ngaphaya kwamabanga asemgangathweni: Ayizizo zonke i-cobalt alloys eziziphatha ngendlela efanayo. I-AMS 5387 iphendula ngokwahlukileyo kumazinga okupholisa kuneendlela ezisekelwe kwi-T800. Ingcali yokwenyani igcina intsebenziswano yobugcisa kunye nabanikezeli bezinto eziqinisekisiweyo-kwaye iqinisekisa ininzi yokushisa nganye ngokuchasene ne-ASTM E112 (ubungakanani bengqolowa), i-ASTM E353 (uhlalutyo lweekhemikhali), kunye neengqungquthela ezichazwe ngumthengi.
- Uzinzo lweDimensional kuzo zonke iinkqubo zomxube: Uninzi lwee-gravity castings ezisebenza ngokuphezulu zifuna umatshini we-CNC emva koko. Ukuba indlu yokuphosa ayingomniniyo iziko lomatshini-okanye ayinayo i-GD&T-ekwaziyo ii-CMM kwindawo-umngcipheko wokunyamezelana okuqokelelweyo kuyaphindaphindeka. Silinganise ukuya kuthi ga kwi-± 0.12 mm ukutenxa kukulungelelaniswa okubalulekileyo xa ukuphosa kunye noomatshini bahlulwa kubathengisi.
- Ukulandeleka kwebhetshi epheleleyo phantsi kwilog enyibilikayo: Kwi-oyile nerhasi okanye ii-OEMs eziqhutywa ngoxinzelelo olukhulu, "ukulandeleka" kuthetha ukwazi ukuba yeyiphi intlawulo yesithando somlilo evelisiweyo ukuba yeyiphi na umjikelo wobushushu owenziweyo, kwaye ngowuphi na umsebenzi osayineyo xa kuhlolwa okokugqibela. Akukho zigodo zamaphepha. Akukho batch-number guesswork.
- Ukuqinisekiswa okusebenzayo-hayi nje ukuthotyelwa komda: Indlu yevalve yoxinzelelo inokudlula iitshekhi zeCMM kodwa isavuza phantsi kwe-350 bar. Iifektri ezikumgangatho ophezulu zenza uvavanyo lwe-hydrostatic, ukuhlolwa kwedayi nge-ASTM E165, kunye nokuqinisekiswa kweprototype-level flow-path path ngaphambi kokukhulula amanqaku okuqala.
Yintoni etyhilwa ziiProjekthi zeHlabathi zokwenyani malunga nokuVula kweNkqubo
Qwalasela iodolo yamva nje yeerola zeshaft yemoto yobunjineli kwi-winch centre. Inxalenye ibifuna ubulukhuni be-HRC obuyi-42, ukugqiba komphezulu ≤Ra 0.8 µm kwiijenali ezithwele umthwalo, kunye ne-zero ye-porosity yangaphakathi ngaphakathi kwe-5 mm yesitulo sokuthwala. I-generic foundry icaphule iiveki ezili-12 kwaye yala uxanduva lokwahluka kwe-microstructure. Isisombululo sivela kwiziko elenza ukugalelwa kwesanti *kunye* nonyango lobushushu endlini, kusetyenziswa i-optical emission spectroscopy kuyo yonke i-ladle egalelwe, kunye neeprofayili zokuqina eziqinisekisiweyo ezinemephu ye-Rockwell B/C yecandelo elinqamlezayo. Ukuvunywa kwenqaku lokuqala kuthathe iintsuku ezisi-8—kungekhona iinyanga.
Elinye ityala libandakanya iiplagi ze-cobalt alloy yeendibano zempompo ze-subsea. Ijometri yayiquka amacandelo anodonga olucekethekileyo (2.3 mm nominal) kunye neradiya yangaphakathi encinci njenge-R0.5 mm. Uyilo olusemgangathweni lokungena lubangele ukubanda kwangaphambi kwexesha kunye nokuvalwa okubandayo. Umthengisi ophumeleleyo uphinde waqulunqa inkqubo yembaleki usebenzisa i-software yokulinganisa ukuqinisa-kwaye waqinisekisa imodeli kunye ne-thermocouple-mapped iqondo lokushisa ngexesha lokuthulula uvavanyo. Olo hlobo lokuphindaphinda lusebenza kuphela xa iinjineli zokuphosa zihleli ecaleni kwee-metallurgists kunye nabaprogram be-CNC yonke imihla.
Ukukhetha uMlingane Wakho: Ngaphandle kweencwadana kunye neZatifikethi
Iziqinisekiso zibalulekile-kodwa zizinto zokucoceka, kungekhona abahluli. I-ISO 9001 ziziteki zetafile. Yintoni ehambisa inaliti bubungqina bokusombulula ingxaki yesizinda-specific: Ngaba bayapapasha izifundo ze-hydraulic valve casting isivuno sokuphucula? Ngaba banokubelana ngedatha yokujonga i-thermal ukusuka kwi-10 yabo yokugqibela ye-AMS 5387 yokuthulula? Ngaba iingxelo zabo ze-QC ziquka iifoto ze-microstructure-kungekhona nje amanani obunzima?
Kwakhona jonga iiflegi ezibomvu: uyilo lwesango lesango “ubukhulu obunye”, ukungakwazi ukubamba ±0.05 mm kwiifitsha zedatum, okanye ukuthembela kwizicoci zobushushu zomntu wesithathu ngaphandle kokuqinisekiswa kwenkqubo edibeneyo. Ezi zibonakaliso zahlula amandla-ayidibanisiweyo ngokuchanekileyo.
Kwiinjineli ezikhangela amacandelo omxhuzulane namhlanje, isigqibo asikho malunga neendleko ngekhilogram nganye. Kumalunga nexabiso lilonke lobunini: ukulungiswa kwakhona okumbalwa, imijikelo ye-NPI ekhawulezayo, kunye nokusilela kwibala elinguziro kwiindawo ezigcina iimpompo zisebenza, ukutywinwa kweevalvu, kunye nezithuthi zisebenza kwindawo egqithisileyo. Oko kuthembeka kuqala nge umzi-mveliso wokuphosa umxhuzulane ephatha yonke ithululo njengovavanyo olulawulwayo-kunye nomzobo ngamnye wabathengi njengenkcazo yokusebenza.
