Xa iinjineli zichaza inxalenye emele ibambe ukunyamezela kwe-± 0.02 mm, iphile kwi-400 ° C ngebhayisikile ye-thermal, kwaye ixhathise ukhukuliseko oluvela kwi-slurry e-abrasive-akukho ndawo yokuqagela. Kulapho a utyalo-mali lwemveliso Foundry ngoqeqesho oluqinisekisiweyo lwe-metallurgical lwenza umahluko phakathi kokusilela ebaleni kunye nobomi benkonzo yeminyaka eli-15. Sizibonele mathupha: impompo ye-hydraulic yezindlu yaqhekeka kwi-8,000 psi ngexesha lokuqinisekiswa-kungekhona ngenxa yoyilo, kodwa ngenxa yokuba i-microstructure ye-as-cast iqulethe i-porosity ye-shrink engabonakaliyo kufuphi nesihlalo se-valve. Ulungiso aluzange lusetyenziswe kwakhona. Yayitshintshela kwiqabane elilawula i-alloy melt chemistry, iqokobhe lokomisa ukufuma, kunye namazinga erempu athotywayo-hayi nje "izahlulo zokuphosa," kodwa iinjineli zokusahlela.
Ukuchaneka Kuqala Phambi Kokugalela Kokuqala
Ukuchaneka kotyalo-mali okwenyani akufezekiswanga ezikweni. Iqala ngokulandeleka kwezinto kunye nenkqubo yokuphindaphinda. Kwindawo yethu ehambelana ne-ISO eQingdao, yonke ibhetshi ye-cobalt-nickel alloy ithwala amaxwebhu aqinisekisiweyo aqinisekisiweyo-ukusuka kuhlalutyo lwe-ingot eluhlaza (AMS 5387, ASTM F75) ukuya kwiziphumo zokugqibela ze-tensile. Asiyamkeli ikhemistri "eqhelekileyo". Siqinisekisa i-chromium, i-molybdenum, kunye nomxholo wekhabhoni ngaphambi kokugalela-kwaye sibhale yonke ipharamitha: iqondo lobushushu beqokobhe, ixesha lokuhlala elidityanisiweyo, ubude bexesha lokufunxa, kunye nesantya sokugalela esisivacuum. Ngoba? Ngenxa yokuba i-2 ° C itenxa kwi-mold preheat itshintsha izinga lokuqiniswa ngokwaneleyo ukuhambisa ukuhanjiswa komda we-carbide kwi-T800-grade superalloys. Oko kuchaphazela ngokuthe ngqo ukuxhathisa ukudinwa kwizindlu zepiston pump cylinder phantsi komthwalo we-cyclic.
Siye saqinisekisa oku kuyo yonke imveliso eyi-127 ye-AMS 5387 cobalt alloy 6 iipump parts. Amacandelo afakwe phantsi kweeparamitha ezilawulwayo abonise i-31% ephezulu kumjikelo ophantsi wokudinwa kubomi obuchasene nejeyometri efanayo kusetyenziswa iisetingi zomgangatho wevenkile. Umahluko yayingengoomatshini-yayikukugalela ngokwayo.
Ukudityaniswa okuthe nkqo akusiyo i-Buzzword-Yi-inshurensi elinganayo
Abanye ababoneleli bangaphandle bagqibezela. Abanye baphatha ukuphosa kunye ne-CNC njengamasebe ahlukeneyo. Siyabadibanisa. Umzi-mveliso wethu wotyalo-mali owenziweyo ujongana nayo yonke into: ukwenziwa kweqokobhe leceramic, ukuphosa ngokuchanekileyo, ukuphelisa uxinzelelo lonyango lobushushu, i-multi-axis CNC machining (kubandakanya i-5-axis contouring yeendlela zokuhamba zangaphakathi), kunye nonyango olusebenzayo lomphezulu olufana ne-HVOF tungsten carbide coating. Oku kuphelisa i-inter-facility dimensional drift-uhlobo olujika i-GD & T-icacisiwe ye-0.015 mm yokunyamezela kwi-stack-up ye-0.032 mm emva kwe-handoffs emithathu.
- Iivalvu zoxinzelelo ezenziwe ngokuthe ngqo kwizithuba ezivaliweyo-akukho kulungiswa kwesibini kuyadingeka
- Iziseko zempompo ezineeflange ezidityanisiweyo zokuxhoma kunye namazibuko olwelo, zonke zibanjelwe kwi-ASME B16.34 Class 600 tolerances
- Iirola zeshafti yemoto yobunjineli ezinemigangatho yokunxiba eqinileyo kunye nengqibelelo engaphantsi komhlaba engonakalisiyo.
Xa i-OEM yaseYurophu idinga indawo ye-cobalt alloy nozzles kwiinkqubo zokuthoba uxinzelelo oluphezulu, umboneleli wabo wangaphambili wahambisa iinxalenye ezifuna i-100% yokwenziwa ngokutsha ukuze kuhlangatyezwane ne-bore concentricity specs. Sihambise iiyunithi ezisebenzayo zokuqala-kuba inkqubo yethu ye-CNC ifunda ngokuthe ngqo kwidatha ye-CT scan, kungekhona imodeli ye-CAD yethiyori.
Ulawulo loMgangatho oSebenzayo, hayi nje iiRekhodi
“Ukuhlola” akuthethi nto ukuba kwenzeka kuphela ekupheleni. Inkqubo yethu yekhwalithi ifakela ukuqinisekiswa kweendawo zokuhlola ezine ezingenakuxoxisana: ukuqinisekiswa kwezinto ezingenayo, ukulinganisa kwe-CMM kwi-process emva komatshini obunzima, i-profilometry ye-optical kwiindawo zokutywinwa okubalulekileyo, kunye novavanyo lokugqibela olusebenzayo-kubandakanya ukuxinzelela ukubola koxinzelelo kwi-1.5 × uxinzelelo lokusebenza. Inxalenye nganye ifumana ithegi ye-ID ekhethekileyo edityaniswe kwirekhodi yayo yedijithali epheleleyo: uhlalutyo lwembonakalo ye-melt, ijika lembali ye-thermal, ingxelo ye-metrology yokulungelelanisa, kunye nemephu erhabaxa yomphezulu.
Siye sabuza abathengi: "Ngaba ungaqinisekisa ukuba akukho porosity kwindawo yesitulo sevalvu?" Impendulo nguhayi-siqinisekisa ukubhaqwa. Ukuba ukuskena kwethu kwe-ultrasonic kuchonga nayiphi na into ebonisa ngaphezu kwe-ASTM E1815 iNqanaba 2, siyayilahla inxalenye. Akukho ngaphandle. Olo qeqesho lugcine izinga lesiphako sePPM singaphantsi kwe-187 kumishini ebaluleke kakhulu ye-hydraulic components kwiinyanga ezingama-37 ezidlulileyo.
Unikezelo Lokwenene Lwehlabathi—Asiloxesha Nje Elithenjisiweyo Lokukhokela
Izithembiso zexesha lokukhokela zithetha kancinci xa iodolo yeprototype ithengisa kangangeentsuku ezili-11 ilinde ukuqinisekiswa kwezinto. Sigcina i-AMS 5387, i-F75 eqinisekisiweyo, kunye ne-stainless steel 17-4PH kwi-heats ezininzi-kunye neengxelo ezipheleleyo zovavanyo lwe-mill kwifayile. Kwiiprojekthi ezingxamisekileyo, sinokuqalisa ukwenziwa kweqokobhe kwiiyure ezingama-48 zokuvunywa komzobo. I-WIP yethu enqabileyo ilandelelanisa i-WIP ngeempawu ze-Kanban-hayi i-spreadsheets-kunye ne-avareji yethu yokuhanjiswa kwexesha kwii-odolo ze-volume medium-volume (50-500 pcs) zimi kwi-98.4%, ziqinisekiswe ngophicotho-zincwadi lweqela lesithathu kulo lonke elaseMntla Melika kunye nokuthunyelwa kwe-EU.
Omnye umenzi wempompo waseMzantsi-mpuma we-Asia unciphise ixabiso elipheleleyo lokuhlala phantsi nge-22% emva kokutshintshela kuthi-kungekhona ngenxa yokuba ixabiso leyunithi yethu yehla, kodwa ngenxa yokuba bacima iindawo ezintathu zokuhlola, banqumle i-scrap ukusuka kwi-14% ukuya kwi-0.9%, kwaye bafumana impendulo yoyilo-for-manufacturability ngaphambi kokuzinikela kwesixhobo.
An utyalo-mali lwemveliso Foundry ufumana ukuthenjwa ngeencwadana, kodwa nge-microstructures ephindaphindiweyo, imbali ye-thermal ebhaliweyo, kunye nozinzo lwe-dimensional kumjikelo we-10,000. Amalungu esinyithi achanekileyo awanyamezeli ukungacaci. Nathi asikwenzi oko. Ukuba icandelo lakho elilandelayo lifuna ngaphezu kokunyamezela okuqhelekileyo-ukuba kufuneka lenze apho ukungaphumeleli kungeyona inketho-qala ngenkqubo yokuphosa, kungekhona umyalelo wokuthenga.
