Izisombululo zefektri yokulahla isanti zifuna ngaphezulu kwesinyithi esityhidiweyo kunye nokungunda. Bafuna ulawulo lwe-dimensional phantsi koxinzelelo lwe-thermal, ukuhambelana kwe-microstructure kwi-50-kg yezindlu zempompo, kunye nokunyaniseka komphezulu osinda kwi-300-bar hydraulic cycling-ngaphandle kokuphinda kusetyenzwe. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye saphosa ngaphezu kwe-12,000 yentsimbi kunye nezixhobo zentsimbi ukususela ngo-2018 apho ukungaphumeleli akusiyo i-scrap-ixesha lokuphumla elingacwangciswanga kwi-oil manifold offshore okanye i-cavitation kwipompo ye-slurry yemigodi. Yiyo loo nto "ifektri yokuphosa isanti yoshishino" ithetha into echanekileyo apha: hayi umthamo, kodwa ukuphindaphindwa okuqinisekisiweyo kwi-high-alloy, izicelo zokunyamezela okuphantsi.
Ukuphoswa Kwesanti Okubambe i-GD&T-Hayi nje iMilo
Uninzi lweevenkile zokulahla isanti zidibana ne-ASTM A159 okanye i-EN-GJL-250 i-tensile specs. Bambalwa babamba i-±0.15 mm kwi-ID ye-320-mm yesilinda emva kokuvuthululwa kunye nokunciphisa uxinzelelo. Senza njalo-kuba inkqubo yethu iqala ngaphambi kokuba ipateni ichukumise isanti. Iinjineli zethu ziphonononga ii-callouts zakho ze-GD&T *phambi* koyilo lokungunda, ukubeka iflegi apho ii-engile zedrafti zingqubana nokunyamezelana kwesikhundla okanye apho umngcipheko wokutshintsha ungaphezulu kwemida yokusebenza. Umzekelo, izindlu zepiston pump cylinder zifuna ukugxila ≤0.08 mm phakathi kwebhore kunye nobuso obuxhonywe ngeflange. Iinkqubo eziqhelekileyo zesanti eluhlaza zikhukuliseka ngaphaya kwe-0.25 mm. Sisebenzisa isanti ye-silica ene-resin-bonded kunye ne-controlled permeability (120-140) kunye neebhokisi ezichanekileyo ezichanekileyo ezifakwe kwi-± 0.05 mm-emva koko uqinisekise ukubunjwa nge-Zeiss CONTURA CMM ngokuthelekisa i-CAD epheleleyo. Akukho ngqikelelo. Hayi "isondele ngokwaneleyo."
Apho i-Cobalt Alloys Misa ezinye ii-Foundries
AMS 5387 ingxubevange yecobalt? Imilomo ye-T800 esekwe kwinaliti eludaka oluludaka? Le ayiyongxaki yokuphosa-yimigibe yesinyithi. Izingundo zesanti eziqhelekileyo ziyaqhekeka phantsi kwe-T800's 1,350 ° C ubushushu obugalelayo. Ukhukuliseko lwesanti lungcolisa ukunyibilika. Ukukhula kweenkozo kutshabalalisa ubomi bokudinwa. Sisombulula oku ngokwemigangatho emithathu: Okokuqala, iimolds ezenziwe nge-ceramic-coated kunye ne-zirconia exhasayo zixhathisa ukothuka kwe-thermal kwaye zithintele ukucholwa kwe-silicon. Okwesibini, ukugalela okuncediswa yivacuum kunciphisa isiphithiphithi-kwaye kuphelisa irhasi evalelweyo eyenza i-microporosity kwindawo yokuqina kacobalt. Okwesithathu, isisombululo se-post-cast annealing kwi-1,180 ° C ± 5 ° C, ebanjwe kwiiyure ze-4 kwi-oven-controlled furnaces, emva koko i-air-cooled ukutshixa kwi-uniform Laves-phase dispersion. Isiphumo: AMS 5387 iinxalenye zidlula ASTM E112 ubungakanani beenkozo 4–6 ngokungaguqukiyo. Abathengi banika ingxelo ye-3.2 × ubomi obude benkonzo ngokuchasene nokuphoswa kokhuphiswano kwizihlalo zevalve yempompo yoxinzelelo oluphezulu.
Kutheni udibaniso oluthe nkqo lubetha "Ukuphosa + ukutshiza" i-Handoffs
Abanye ababoneleli baphosa indlu, bayithumele kwivenkile ye-CNC, emva koko bayithumele kwakhona ukuze igqitywe. Ugqithiselo ngalunye longeza umngcipheko: ii-datum ezingalunganga, umonakalo ongabhalwanga wokuphatha, iirekhodi ezilahlekileyo zokuphatha ukushisa. Sisebenza ngomatshini zonke iivalvu zentsimbi—iivalvu zoxinzelelo, iirola zeshafti yewinch, iziseko zempompo—kwikhampasi enye, sisebenzisa imiphezulu yedatum njengeembekiselo zokuseta. Oomatshini bethu be-5-axis DMG MORI NTX 1000 basika i-bores yokugqibela ngelixa bebambe umgca wokwahlukana wokubumba njenge-Z-zero. Oko kuphelisa impazamo eyongezelekayo ekunyuseni kwakhona. Ikwasivumela ukuba sishiye isitokhwe sobuchule kwiizowuni zokunxiba ezibalulekileyo-0.8 mm kubuso beplagi ye-T800, umzekelo-ukusila kokugqibela kuphumelela iRa 0.4 µm *emva* konyango lobushushu, hayi ngaphambili. Ukulandeleka kwakhelwe ngaphakathi: inxalenye nganye iphethe ikhowudi ye-QR edibanisa kwi-log ye-melt, ingxelo ye-X-ray, imephu yobunzima, kunye neziphumo ze-CMM. Akukho mikhondo yamaphepha. Akukho ngqikelelo.
Ukuhanjiswa Kokwenene—Asiloxesha Lokukhokela Elithenjisiweyo
"Iiveki ezi-8-12" azithethi nto xa umgca wokudityaniswa kwesithuthi sobunjineli uyeka kwiveki ye-10. Sizibophelela kwimihla yokuhanjiswa kuphela emva kokuqinisekisa izixhobo, iziqinisekiso zemathiriyeli, kunye nomthamo-kungekhona emva kokucaphula. Iiseli zethu zokuvelisa ezibhityileyo ziqhuba imijikelo yebhetshi emiselweyo: iseti enye yokungunda ngefestile yeentsuku ezili-14, max 40 iiyunithi ngebhetshi nganye yokuphosa intsimbi enzima. Oko kugquma i-WIP, kuveze imiqobo kwangethuba, kwaye kuyasiqinisekisa ukuba sithumela iiprototypes ngeentsuku ezingama-22 — hayi “kamsinyane kangangoko kunokwenzeka.” Kunyaka ophelileyo, i-98.7% yee-odolo zithunyelwe ngomhla okanye ngaphambi komhla wokuzibophelela. Ukulibaziseka kwe-1.3%? Zonke zilandwa kwiinguqu zobunjineli ezicelwe ngumxhasi *emva* kokuvunywa kwepateni—hayi ukusilela kwangaphakathi. Sabelana ngeedashbhodi zemveliso yexesha lokwenyani kunye nabathengi abaphambili: ubume bokubumba, ukugalela izingodo, izitampu zexesha lokuhlola. Ukungafihlisi ayithengisi. Yindlela okuphepha ngayo ukulwa nomlilo.
Ukuba ufuna imveliso yesanti yokugalela isanti ephatha umzobo wevalve yakho yoxinzelelo njengecandelo elibalulekileyo lokubhabha-hayi inxalenye yempahla-udinga ulawulo olungqiniweyo malunga nokuziphatha kwe-alloy, inyaniso ene-dimensional, kunye nobunini bokuphela ukuya ekupheleni. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihambisa loo nto. Hayi njengesithembiso. Njengesiphumo esiphinda-phindayo.
