Xa iinjineli zichaza Utyalo-mali lokugalela iinxalenye umzi-mveliso iinkonzo ze-valve ze-hydraulic, izindlu zempompo, okanye i-winch shafts, azithengi nje isinyithi-zithenga ukuzinza kwe-dimensional phantsi koxinzelelo lwe-300-bar, ukunyaniseka kwe-microstructure emva kokunyanga kobushushu, kunye nokunyamezela kwe-zero kwi-porosity kwi-cobalt-nickel alloy nozzles. Siye sabona iiprojekthi ezininzi kakhulu zivaliwe ngenxa yokuba umthengisi uthembise "ukuphosa ngokuchanekileyo" kodwa wahambisa iindawo ezisilele ukuqinisekiswa kweCMM kwinqanaba lokugqibela lokuhlola-ingakumbi kumacandelo e-AMS 5387 okanye i-T800-grade apho ubulukhuni kunye nesikhokelo sokuhamba kweenkozo kuchaphazela ngokuthe ngqo ubomi bokudinwa.
Kutheni le nto uTyalo-mali olulahlwayo ingeyiyo nje enye iNkqubo-Sisinyanzelo seNkqubo
Utyalo-mali lugqwesa apho ukuchithwa kwesanti kungabikho sisombululo kunye ne-CNC machining ibetha imida yezinto. Kodwa impumelelo iqala ixesha elide ngaphambi kokuba iphethini ye-wax inyibilike. Kwiziko lethu elise-Qingdao, yonke iodolo iqala ngokugcinwa kwesango ngentsimbi: iziqinisekiso zezinto ezikrwada ziqinisekisiwe *phambi kokufakwa kwe-alloying, hayi emva kokuphoswa. Siyala iibhetshi kunye ne-0.02% ukutenxa kwi-chromium okanye kwi-molybdenum umxholo we-cobalt-based alloys-kuba loo mda uthatha isigqibo sokuba iplagi ye-AMS 5387 iphila kwi-12,000 ye-thermal cycle kwi-pump ye-offshore manifold.
Silinganise amazinga okucutheka kuwo wonke ama-47 obushushu obuninzi botyalo-mali lwentsimbi engenastainless-kwaye safumanisa ukuba iyantlukwano ayizenzekelanga. Ilandelela ngokuthe ngqo ngoyilo lwesango, iqokobhe lokomisa ukufuma, kunye nesantya serempu ye-preheat. Yiyo loo nto amaxwebhu ethu enkqubo evala iiparamitha ezili-19-hayi nje "ukugalela ubushushu" kunye "nexesha lokupholisa." Umzekelo, izindlu zepiston pump cylinder zifuna ukuqina okulawulwayo ukunqanda i-centerline microporosity. I-1.2°C/min isantya sokupholisa umahluko sitshintsha isithuba sengalo ye-dendrite nge-8.6 µm. Oko kunomlinganiselo. Iyenzeka loo nto.
Ukudityaniswa okuthe nkqo kuSombulula iiNzululwazi zokwenyani-hayi nje aBango lokuThengisa
Abanye ababoneleli ngamashishini machining, unyango ubushushu, okanye ukugqiba umphezulu. Oko kwaphula uxanduva. Xa ivalve yoxinzelelo lwendlu ijijekile emva kobushushu, ingcibi yatyhola i-caster; uCaster watyhola umthengisi weziko lomlilo. Singabanikazi bontathu amanyathelo. Iiseli zethu ze-CNC zihamba kunye nemigca yokuphosa-ngoko inxalenye ephonswe kwi-8 ekuseni ilungisiwe, i-rough-machined, i-stress-rexing, i-finishing-machined, kunye ne-CMM-iskenwe nge-4. Umsebenzisi ofanayo. Iilog zokulinganisa ezifanayo. I-ID yokulandeleka efanayo.
Oku akukho lula-lulawulo oluqhutywa yi-physics. Ukuphoswa komatshini ngelixa zisezinzile ngokwe-thermal kuthintela ukuphinda usebenze kwakhona kwintsalela yoxinzelelo. Sehlise amaxabiso ezinto ezilahliweyo ngama-63% kwiziseko zempompo yentsimbi engenasici ngokutshintsha ukugqiba ukujika ukuba kwenzeke kwiiyure ezi-4 zokufunxa. Kwaye ewe-sifaka iqondo lobushushu elisezantsi kwivenkile kunye nokufuma kwibhetshi nganye. Ngenxa yokuba ujingi we-5 ° C utshintsha izinga lokunxiba isixhobo kwi-alloy ye-T800 eqinile nge-17%.
Yintoni ngokwenene abaVavanyayo abathengi (kwaye kutheni besilela abanye)
Abathengi ababuzi ukuba "Ngaba uyakwenza utyalo-mali?" Bayabuza: "Ngaba ungabamba ±0.015 mm kwi-320-mm-diameter bore kunye ne-3.2 µm Ra ukugqiba, usebenzisa i-cobalt alloy, kunye nokuhambisa iicerti zezinto ezipheleleyo kunye neengxelo ze-CMM nge-ASME Y14.5 nganye?" Nantsi into eyahlula ukuphunyezwa kwizithembiso:
- Ukuqinisekiswa kwe-GD&T kwenzeka ngaphambi kokuba kuqale isixhobo—kungekhona emva kwenqaku lokuqala. Sifaka iflegi yongquzulwano lwedatum, ukunyamezelwa kweprofayile okungahambelaniyo nobungqingqwa beqokobhe, okanye iradio iqine kakhulu ukuba ihambe ngodaka lweceramic.
- Akukho mjikelo "oqhelekileyo" wokuphatha ukushisa. Sihlengahlengisa ixesha lokufunxa ngokusekwe kubukhulu becandelo—hayi iinkcazo zekhathalogu. Udonga lwe-45-mm ludinga i-2.3 × ubude kunodonga lwe-12-mm ukulinganisa ukushisa kwinqanaba elinqamlezayo.
- Wonke umlinganiselo obalulekileyo ufumana ukuqinisekiswa kabini: I-CMM yejometri, i-optical comparator ye-edge definition-kuba ubude be-burr bubalulekile kwiindawo zokutywinwa.
Siye saba nabathengi batshintsha phakathi kweprojekthi emva kokufumanisa ukuba umthengisi wabo wangaphambili wayesebenzisa iicerti "zentsimbi engenasici" endaweni yeengxelo zokwenyani zobushushu. Sigximfiza sonke isatifikethi nge-ID yesithando somlilo, inombolo yokugalela, kunye nendawo yokuvavanya ikhuphoni. Akukho ngaphandle.
Apho Ukuchaneka Kudibana Nokusebenza—Ngoku nangokulandelayo
An Utyalo-mali lokugalela iinxalenye umzi-mveliso ufumana ukuthenjwa kungekhona ngeencwadana ezinemifanekiso—kodwa ngendlela ekusingatha ngayo ukungathotyelwa kokuqala. Kwikota yokugqibela, i-OEM ye-hydraulics yaseYurophu isithumelele umzobo onee-callout ze-GD&T ezingqubanayo kumzimba wevalvu. Endaweni yokucaphula ngokungaboniyo, senze imephu yenjongo esebenzayo, sacebisa iindlela ezimbini ezinokuthi zenziwe, kwaye saqhuba i-FEA kuzo zombini ukubonisa umahluko wokusasazwa koxinzelelo. Bakhetha uKhetho B—baza banciphisa ixesha lokuhlanganisa ngama-22%.
Ukujonga phambili, sandisa i-ISO 13485 ukulungela izinto ze-cobalt zodidi lwezonyango kunye nokuqinisekisa ukuqhutywa komsebenzi we-hybrid casting-machining for turbine vane carriers. Kodwa eyona nto iphambili namhlanje ayitshintshi: ukuhambisa amacandelo aphumelele uvavanyo olusebenzayo-hayi nje ukujonga umyinge. Ukuba iprojekthi yakho elandelayo idinga iivalvu zoxinzelelo, izindlu zesilinda, okanye izixhobo zealloy ezenzelwe icobalt ezakhelwe kumthwalo wehlabathi lokwenyani kunye nemijikelo yobomi, qala ngokulandeleka kwezinto, hayi ukuthengisa iziqubulo.
