Xa iinjineli zichaza Iinxalenye ze-Icoloy ialloy, abagcini nje ngokukhetha izinto eziphathekayo-bazibophelele ekuzinzeni kwe-dimensional phantsi kokutshatyalaliswa kwe-thermal, ukunyanzeliswa kwe-corrosion kwindawo yegesi emuncu, kunye nobomi bokukhathala kwiinkqubo eziphezulu ze-hydraulic. Yiyo loo nto ukhetha okulungileyo Umzi-mveliso we-Incoloy alloy parts ayithethi ngexabiso eliphantsi okanye ukucaphula ngokukhawuleza. Imalunga nolawulo olungqiniweyo lwesinyithi, ukwenziwa ngokuphindaphindiweyo kwe-AMS 5387-grade cobalt-nickel alloys, kunye nonyamezelo lwe-zero lokungangqinelani kwe-microstructural kwiibhetshi.
Imiceli mngeni yokwenyani ifuna inkqubo yokwenyani yoluleko-hayi nje isiqinisekiso sealloy
Siye sabona iiprojekthi ezininzi kakhulu xa ababoneleli bedlula ii-certs eziphathekayo kodwa behluleka kwingqibelelo yendawo echaphazelekayo emva kokusika kwe-EDM. Okanye xa ukunyamezela kwe-"as-cast" kuqhutywe ngaphaya kwe-± 0.3 mm kwi-320-mm-diameter piston pump cylinder housing-kubangela ukuvuza kwetywina kwi-4,000 psi. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke inxalenye ye-Incoloy iqala ngokulandeleka, i-Mill-certified T800 okanye i-AMS 5387 billet. Kodwa isiqinisekiso sodwa asiqinisekisi ukusebenza. Siyayiqinisekisa indlela yokuhamba kweenkozo phambi komatshini orhabaxa. Sibeka iliso kwiqondo lobushushu le-interpass ngexesha lokugaya i-multi-axis yemizimba yevalvu ukunqanda uvakalelo lwasekhaya. Kwaye siqinisekisa ubunzima bokugqibela *emva kokunciphisa uxinzelelo-hayi ngaphambili.
Oku akuyothiyori. Kunyaka ophelileyo, isixhobo se-oyile yaseYurophu i-OEM yala amaqashiso amathathu eprototype komnye umboneleli ngenxa yokungahambelani kokufundwa kwe-delta-ferrite kwiiflange ze-Incoloy 825. Iqela lethu liqhube ukulinganisa umjikelezo we-thermal ohambelanayo, uhlengahlengiso lweeparamitha ze-preheat, kwaye unikeze imvume yokupasa yokuqala kwi-Lot #4-enee-MTR ezipheleleyo, iingxelo ze-CMM, kunye nee-macrographs ezinqamlezileyo ezigcinwe kwi-ASME BPVC yeCandelo le-IX.
Ukudityaniswa ngokuthe nkqo kuthetha ukuba akukho zi-handoffs-kwaye akukho ziguquko ezifihliweyo
Uninzi "lweefektri ze-Incoloy alloy alloy" zikhupha ngaphandle, umatshini wangaphandle, okanye ukugqiba ikontrakthi. Oko kudala izikhewu: ukuphosa i-porosity ephoswe kukuhlolwa okubonwayo, ukucinezeleka kwentsalela eyenziwe ngoomatshini ngaphambi kokusila kokugqibela, ukugqiba komphezulu obonakala ugudile kodwa ungaphumeleli kuvavanyo lwesitshizi setyuwa emva kweeyure ezili-120. I-QINGDAO QIANGSENYUAN ingumnini wekhonkco elipheleleyo-ukusuka ekugaleleni utyalo-mali lweziseko zempompo ezinzima ukuya kwi-axis ye-CNC ye-contouring ye-cobalt alloy nozzles, emva koko ukuya kwi-atmospheric annealing kunye ne-electropolished finishes.
Asikuthathi ukuphosa kunye noomatshini njengamasebe ahlukeneyo. Iinjineli zethu ezisisiseko zihlala kunye nabadwelisi benkqubo be-CNC ngexesha lophononongo lwe-DFMA. Xa umthengi ethumela i-GD&T ye-Incoloy 625 winch centre shaft roller, iqela lethu lifaka iflegi apho i-engile yedrafti yesanti ingqubana neendawo ezisebenzayo-kwaye iphakamisa isisombululo esixubileyo: ukuphosa okukufutshane kwe-net-shape + precision ID/OD turning + i-laser-assisted surface yokuqina kwiindawo zokunxiba. Oko kunciphisa ixesha lokukhokela nge-37% kwaye kuphuculwe umphezulu woxinzelelo lwentsalela ye-210 MPa ngokuchasene ne-post-machining induction induction yodwa.
Umgangatho awuhlolwanga-yakhiwe ngaphakathi, umaleko ngomqolo
Iziko lethu elithobela i-ISO liqhuba iindawo ezintathu zokukhangela ezingaxoxisiyo kuwo onke amacandelo e-Incoloy:
- Ukuqinisekiswa kwezinto: Uhlalutyo lwe-Spectrometric + ukuskena kwe-PMI kwiibha ezingenayo, kunye novavanyo lwe-ultrasonic lwe-subsurface discontinuities
- Ukuqinisekiswa kwenkqubo: Umlinganiselo weCMM emva komsebenzi ngamnye obalulekileyo-kungekhona nje ukuhlolwa kokugqibela-kunye neprofilometry ye-optical kwindawo yokutywinwa
- Ukukhutshwa okusebenzayo: Uvavanyo loxinzelelo lwe-Hydrostatic kwi-1.5 × uxinzelelo loyilo, lulandelwa luvavanyo lokuvuza kwe-helium kwi-≤1 × 10⁻⁹ mbar · L / s kwiindibano zevalve
Akukho ngaphandle. Akukho "tenxa evunywe ngumxumi." Ukuba iplagi yealloyi yecobalt ayiphumeleli kuburhabaxa bomphezulu iRa ≤ 0.4 µm kwisitulo sayo esikhone, iyasetyenzwa kwakhona—ayikhululwa ngokuyekwa. Ukulandeleka kubhakwa kwi-: yonke inxalenye iphethe ikhowudi ye-QR edibanisa kwi-batch-specific curve yonyango lobushushu, i-log yesixhobo somatshini, kunye nengxelo yokuhlola. Oko kuyabaluleka xa indibano yakho yempompo ingaphumeleli kuvavanyo lokungcangcazela kwi-12,000 rpm-kwaye kufuneka uzibeke wedwa ukuba ingaba unobangela wawukukwenza ukuncipha okanye ukugqwetheka kwangemva komatshini.
Yintoni eneneni ehambisa inaliti kumaqela okuthengwa kwempahla yehlabathi
Abathengi basibuza imibuzo emithathu ngaphezu kwayo nayiphi na enye:
- "Ngaba unako ukubamba i-± 0.05 mm kwi-280-mm-ubude be-Incoloy 800 yoxinzelelo lwevalve umzimba-ngaphandle kwe-warpage emva kokukhululeka koxinzelelo?" Ewe. Sisebenzisa uyilo lwe-low-distortion fixture, imijikelo yokucotha epholileyo, kunye nemephu ye-CMM yasemva kokunyanga ukuqinisekisa ukuhlala okucaba ngaphakathi kwe-0.08 mm iyonke yokufunda isalathisi.
- "Ngaba uyayixhasa iprototyping yebhetshi encinci ngamaxwebhu agcweleyo-kwanakwiijometri ezingekho mgangathweni njengee-asymmetric AMS 5387 nozzles?" Ewe. I-odolo yethu encinci yeenxalenye ze-Incoloy yesiko yiyunithi enye yokusebenza-enee-MTR ezigcweleyo, iingxelo ezinobungakanani, kunye namakhuphoni okuvavanya izinto ezibandakanyiweyo.
- "Uluphatha njani utshintsho olungxamisekileyo phakathi kwemveliso-njengokutshintsha ukusuka kwi-Incoloy 600 ukuya kwi-625 ngenxa yedatha yokuvezwa kwe-chloride?" Siqinisekisa kwakhona iindlela zokuhamba kwezinto kwiiyure ezingama-48. Hayi "uphononongo lwamaxesha." Hayi "ukuvavanya ukwenzeka." Siqhuba iisampulu ezintsha zokuqina, sihlaziye unyango lobushushu lonyaka, kwaye sikhuphe izicwangciso zokuhlola ezihlaziyiweyo-phambi kokusika isinyithi.
Oko kusabela kuvela kubunjineli bobunjineli-hayi izithembiso zentengiso. Iprojekthi nganye inesikhokelo esizinikeleyo sobuchule esithetha ngokutyibilikayo i-GD&T, iqonda iimfuno ze-microstructure ye-ASTM A494 yeBanga le-CW6MC, kwaye isayine ukukhutshwa kokugqibela.
Ukuba isicelo sakho esilandelayo se-Incoloy sifuna okungaphezulu kokuthotyelwa kwe-alloy-ukuba ifuna i-microstructure eqikelelweyo, ukuziphatha okuqinisekisiweyo komgangatho phantsi komthwalo, kunye nokungacaci kwenkqubo yokuphendula-ke ukhetho alukho phakathi kwabathengisi. Kuphakathi kokwamkela umngcipheko kunye nokuwuphelisa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakhela ukuthembeka okubalulekileyo kubuthunywa, hayi ukuthotyelwa kwemigaqo. Ngenxa yokuba kuxinzelelo oluphezulu, ubushushu obuphezulu, indawo eneziphumo eziphezulu, akukho thuba lesibini lokufumana i-metallurgy ngokufanelekileyo.
