Xa iinjineli zichaza ipowder metallurgy parts izisombululo zeevalvu ze-hydraulic, izindlu zempompo, okanye i-winch shafts eziphezulu, azithengi nje izinto-zikhusela ukuzinza kwe-dimensional phantsi koxinzelelo lwe-bar ye-350, ukunyaniseka kwe-microstructural emva kwemijikelo ye-thermal eyi-10,000, kunye nokunyamezela kokugqiba umphezulu kuqina ngaphezu kwe-± 0.005 mm. Ababoneleli abaninzi bathembisa ukuchaneka. Bambalwa abahambisayo-ingakumbi kwii-alloys ze-cobalt-nickel ezifana ne-AMS 5387 okanye i-T800-grade superalloys apho i-machining chatter, ukuphazamiseka kwendawo echaphazelekayo kubushushu, kunye nokwahluka kwe-batch-to-batch hardness rhoqo kuphazamisa imveliso.
Sizibonele mathupha: isixhobo se-oyile yaseMntla Melika i-OEM ilibazisekile ukuthunyelwa kweeveki ze-11 ngenxa yokuba umlomo wabo "oqinisekisiweyo" we-cobalt alloy waqhekeka ngexesha lovavanyo loxinzelelo-kungekhona kwisiphene soyilo, kodwa ukwakheka kweenkozo okungahambelaniyo kuyo yonke i-castings. Omnye umxhasi ulahle i-62% yezindlu ze-piston pump cylinder cylinder emva konyango lobushushu ngenxa yokwahlulwa kwekhabhoni okungalawulwayo kwisiseko sentsimbi. Ezi ayizizo iimeko ezinzima. Ziyimpawu zokukwazi ukuqhekeka-apho ukuphosa, ukwenziwa, kunye nokuqinisekiswa kwesinyithi kwenzeka kubathengisi abathathu, ngamnye ulungiselela iindleko okanye isantya, hayi ukusebenza komsebenzi.
Yiyo loo nto ulawulo lwenkqubo edibeneyo lubaluleke ngaphezu kwaso nasiphi na isatifikethi esinye. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke iplagi yealloyi ye-cobalt, inxalenye yepompo ye-AMS 5387, okanye ukugaywa kwensimbi engenasici iqala ngokulandeleka kwezinto ezikrwada ukuya kwinani lobushushu kunye nengxelo yovavanyo lokusila-kungekhona nje ii-invoyisi zomthengisi. Siphuhlisa izinto ezibonakalayo kunye nabavelisi abaqinisekisiweyo bealloyi, siqhuba uhlalutyo olungenayo lwe-spectrographic kwi-100% yeebhilethi ze-cobalt-nickel, kwaye siqinisekise ubume be-microstructure nge-metallografi ngaphambi kokuba kuqale ukwenziwa komatshini. Akukho ngqikelelo. Akukho handoffs. Ubungqina obubhaliweyo bokuba umbandela owuodolileyo ngumbandela owufumanayo.
Udibaniso oluthe nkqo alukho ijargon yokuthengisa apha-yindlela esibamba ngayo i-± 0.01 mm GD&T callouts kwiirola ezingezizo eziqhelekileyo kwiziko leshaft kwiiwintshi zemoto yobunjineli. Indawo yethu ethobela i-ISO iqhuba utyalo-mali lwemilomo ye-cobalt eludongeni olucekethekileyo, ukuphosa isanti kwiziseko zempompo ezinobubanzi obukhulu, kunye ne-5-axis CNC machining-konke phantsi kophahla olunye. Oko kuthetha ukuba iqela elifanayo le-metrology liqinisekisa ubungakanani be-cast-cast, ihlola i-bores ebalulekileyo phakathi kwe-machining isebenzisa i-Zeiss CMMs, kwaye lenze uvavanyo lokugqibela olusebenzayo ngokuchasene namazinga okuhamba axelwe ngabathengi kunye ne-torque curves. Xa umxhasi ecela umzimba wevalve ye-T800 ye-alloy yesiko kunye namajelo okupholisa angaphakathi, sagqiba ukuqinisekiswa kweprototype ngeentsuku ze-14-kungekhona ngenxa yokuba siphuthuma, kodwa ngenxa yokuba idatha yokunciphisa i-shrinkage ifakwe ngqo kwimbuyekezo ye-CAM yendlela yesixhobo, ukuphelisa iilophu ezimbini zokuphindaphinda.
- Akukho "ibhokisi emnyama" yesinyithi: Zonke i-cobalt-nickel kunye ne-high-alloy castings zifumana isisombululo se-annealing + ukuguga nge-AMS 2750 nganye, kunye nezigodo zomlilo ezigcinwe iminyaka eyi-10.
- Akukho kukhukuliswa komda: Kwinkqubo yokuhlola i-CMM kumanqanaba amathathu-emva kokurhabaxa, ukugqiba ngesiqingatha, kunye nokupasa kokugqibela-kuthintela impazamo eyongezelekayo.
- Akukho kucaciswa kumbi: Iqela lethu lobunjineli lifakela iflegi ye-GD&T phambi kokucaphula-njengokubuza ukuba kutheni ukunyamezelana kwe-±0.002 mm kusebenza kwi-200 mm yedayamitha yefitsha kwisakhiwo sesanti.
- Akukho nto imangalisayo yokuhanjiswa: Isicwangciso sokuhamba komsebenzi sitshixa ngamaxesha okukhokela kumthamo ophakathi (i-50-500 iipcs) ngaphambi kokwamkelwa kwe-PO-akukho "phantsi komthamo" amagatya
Abanye banokuphikisa ukuba ii-Foundries ezikhethekileyo okanye iivenkile ezizinikeleyo ze-CNC zibonelela ngobuchule obunzulu. Kodwa ubuchule ngaphandle komxholo budala amabala angaboniyo. Ingcali yokuphosa ayiyi kuqikelela ukuba uxinzelelo olushiyekileyo oluvela kubunzima bodonga olungalinganiyo luchaphazela i-ovality yangemva komatshini kwizindlu zevalve yoxinzelelo. Ingcali ye-CNC inokwandisa ixesha lomjikelo ngaphandle kokujonga ukuba amandla okusika agqithise amandla esivuno seplagi ye-cobalt ephethwe ngubushushu. QINGDAO QIANGSENYUAN iibhulorho ukuba umsantsa-kuba iinjineli zethu ziye zayila, baphose, oomatshini, kwaye kuvavanywa phezu 1,200 amacandelo enkqubo impompo unique ukususela 2015. Siyazi xa AMS 5387 kufuneka amazinga feed kancinane ukuphepha umsebenzi lukhuni-kwaye xa T800 ingxubevange izibonelelo ukusuka cryogenic isiqabu uxinzelelo phambi kokugqibela.
Ukujonga phambili, ujoliso lwethu lwe-R&D alukho koomatshini abakhulu okanye kwiikhathalogu ezibanzi. Kukwiinkqubo ezixubileyo: ukudibanisa ukuphosa utyalo-mali olusondeleyo kunye ne-electrochemical machining echanekileyo yeempawu zangaphakathi ezingenakwenzeka ukufikelela ngezixhobo eziqhelekileyo; ukufakela iliso lexesha lokwenyani lobushushu ekuphoseni ukubumba ukulungelelanisa idatha ye-thermal gradient kunye nokusabalalisa kokugqibela kobunzima obuncinci; ukwandisa i-EN 10204 3.2 isiqinisekiso sokhuselo ukubandakanya iikhemikhali ezipheleleyo + zoomatshini + neengxelo ze-NDT kwiqashiso ngalinye elithunyelweyo. Ngenxa yokuba kwizicelo ezibaluleke kakhulu kwimishini-ukusuka kwi-subsea hydraulic manifolds ukuya kwi-high-pressure-pressure injection yamafutha-umahluko phakathi "kwemisebenzi" kwaye "ayiyi kusilela" uhlala kwiinkcukacha ozilawulayo, hayi ezo uzikhuphayo.
Ukuba iprojekthi yakho elandelayo ifuna ipowder metallurgy parts i-rigor-kungekhona nje umthamo-ukuqala ngokulandeleka kwezinto, ukufuna ubungqina be-metrology kwi-process, kwaye ugxininise kwiimpendulo zobunjineli ngaphambi kokugqiba imizobo. Amalungu owakhankanyileyo namhlanje aya kusebenza apho ukungaphumeleli kungeyiyo inketho. Khetha iqabane eliphatha konke ukunyamezelana njengesivumelwano.
