Mainjiniya akamatchula mbali za AMS 5387 Stellite zamapampu a hydraulic, mavavu othamanga kwambiri, kapena makina opangira ma winchi akunyanja, samangosankha zinthu - akusankha chitsimikizo cha magwiridwe antchito. AMS 5387 yochokera ku Cobalt imapereka kukana kwapadera kwa ndulu, kuyabwa, ndi kuwonongeka kwa kutentha komwe zitsulo zosapanga dzimbiri zimalephera. Koma zopangira zopangira sizitanthauza pang'ono popanda kuchitidwa molondola. Ndicho chifukwa chake kufufuza kuchokera ku AMS 5387 Stellite gawo fakitale yokhala ndi zitsulo zotsimikiziridwa, kuthekera kolimba kwa GD&T, komanso kutsata zolembedwa sikuli kosankha-ndikofunikira kwambiri.
Chifukwa chiyani AMS 5387 Imafunikira Zambiri Kuposa Kungoponya Kapena Kuchitcha
Tawona ma projekiti ambiri akuyimitsidwa pachiwonetsero chifukwa ogulitsa adatenga AMS 5387 ngati aloyi wina. Si. Mapangidwe ake apamwamba a cobalt-nickel-chromium-molybdenum amapangitsa kuti ikhale yovuta kwambiri, imagwira ntchito molimbika panthawi yopangira makina komanso kukhudzidwa ndi kutentha kwa kutentha panthawi ya kutentha. Kudutsa kamodzi kokhala ndi zida zolakwika za geometry kumatha kuyambitsa kusweka. Kuzizira kofulumira pambuyo poyatsa njira kumatha kusintha kagawidwe ka carbide - moyo wakuvala wonyozeka mpaka 40% pakuyesa kumunda. M'mayesero athu opangira, tidapeza kuti magawo a AMS 5387 omwe amapangidwa pamakina ovala adawonetsa 22% kuuma kwapamtunda (Ra> 1.6 µm) motsutsana ndi zomwe zidamalizidwa pazida zokhazikika, za PCD-ndipo kusiyana kumeneku kumagwirizana mwachindunji ndi kutayikira kwa chisindikizo msanga m'nyumba zapampu ya piston.
Ichi ndichifukwa chake kuphatikiza koyima ndikofunikira. An AMS 5387 Stellite gawo fakitale Ayenera kuwongolera unyolo wonse: certified T800-grade billet sourcing, kuponyedwa kwa ndalama ndi mitengo yokhazikika yokhazikika, kuchepetsa nkhawa musanapange makina ovuta, CNC yokhala ndi zida zenizeni zenizeni, ndi HIP yomaliza (kukanikiza kwa isostatic) pakafunika. Palibe ma handoffs. Palibe kusiyana kwa batch-to-batch pakuuma (HRC 38–45) kapena kubalalitsidwa kwa carbide.
Mphamvu Zinayi Zosakambirana Zomwe Muyenera Kuzitsimikizira
Musanatulutse zojambula, funsani wogulitsa wanu mafunso anayi awa-ndipo funsani umboni:
- Kodi mumatsimikizira mabilu a AMS 5387 omwe akubwera ndi kusanthula kwathunthu kwa PMI +? Timakana 3.7% ya maere omwe akubwera kutengera masinthidwe ang'onoang'ono a Mo/Cr - ngakhale mkati mwa malire a ASTM - chifukwa amakhudza mapangidwe a gawo lachiwiri ndikukweza mozungulira.
- Kodi mutha kukhala ndi ± 0.015 mm pamamita osindikizira ovuta mu nyumba ya silinda ya 320 mm? Kuthekera kwathu kotsimikiziridwa ndi CMM pazitsulo za cobalt ndi ± 0.012 mm-osati "mpaka" koma zimakwaniritsidwa mosalekeza pazigawo zonse za 50+.
- Kodi mumachita pambuyo Machining akupanga anayendera onse kuthamanga munali zigawo zikuluzikulu? Inde, ndipo timasunga zolemba zonse za digito zomangika ku kutentha kwambiri ndi ID ya opareshoni.
- Kodi mutha kutengera mawonekedwe a microstructure m'malo osinthidwanso? Inde, kudzera m'malo okhala ndi laser cladding pogwiritsa ntchito AMS 5387 ufa wokhala ndi chemistry yofananira, ndikutsatiridwa ndi HIP ndikumaliza kukonza.
Kumene Ogulitsa Okhazikika Amachepa - Ndipo Zomwe Zimagwira Ntchito M'malo mwake
Opanga ena amatulutsa makina a AMS 5387 kumalo ogulitsa ntchito wamba. Ife tinayesera izo kamodzi. Chotsatira? Magulu atatu okanidwa chifukwa cha macheza apansi pamadzi osawoneka ndi maso - koma adadziwika pambuyo pa maola 200 akuyesa mavalidwe mwachangu. Choyambitsa: kusakhazikika kokwanira mu mphero zawo za 3-axis komanso kusowa kwa ma database amtundu wa cobalt.
Kukonzekera sikunali makina ochulukirapo - kunali kuwongolera kozama. Tsopano timagwiritsa ntchito malo olimba, okhazikika a granite-bed 5-axis machining omwe ali ndi mphamvu zophatikizira zoziziritsa kuzizira (± 0.5 ° C), kayeseleledwe ka zida komwe kamatengera kuchuluka kwa dzino pa dzino * musanadulidwe, ndikutsimikiziranso kukhudza-kufufuza pakadutsa movutikira. Kwa ma geometri ovuta ngati ma cobalt alloy nozzles okhala ndi ma convergent-divergent amkati, timaphatikiza kuyika ndalama kwa mawonekedwe apafupi ndi ukonde ndi ma electrochemical machining (ECM) pomaliza -kuchotseratu kupsinjika kwamakina.
Zochitika Zenizeni Zapadziko Lonse: Kuchokera Kujambula mpaka Kutumiza Kumunda
Makasitomala m'modzi amafunikira ma AMS 5387 center shaft rollers opangira ma winchi agalimoto zapanyanja - malinga ndi kumizidwa m'madzi amchere, ma radial 120 kN, komanso kuyimitsa pafupipafupi. Omwe amawagulitsira m'mbuyomu adapereka zodzigudubuza zomwe zidatha maola 4,200 ogwirira ntchito asanayambike. Mtundu wathu, wokhala ndi makina okhathamiritsa a carbide network komanso Ra ≤ 0.4 µm kumaliza pansi, udapitilira maola 11,800 muutumiki womwewo - pafupifupi katatu moyo wonse. Palibe kukonzanso. Palibe kukweza kwakuthupi. Kungowongolera mwamphamvu pazomwe zimachitika pakati pa ng'anjo yoyambira ndi malo omaliza a QC.
Chotsatiracho chikuwonetsa momwe a AMS 5387 Stellite gawo fakitale imagwira ntchito: osati ngati wogulitsa, koma monga chowonjezera cha gulu lanu la uinjiniya. Timawunikanso ma callouts a GD&T koyambirira, kuyika zoopsa zomwe zingachitike pamakina m'magawo osakhazikika a radii kapena makoma opyapyala, ndikupereka zolemba zonse za PPAP — kuphatikiza ma chart a kutentha, malipoti a CMM, ndi zithunzi za microstructure — nkhani yoyamba isanavomerezedwe.
Lingaliro Lomaliza: Kulondola Sikuyezedwa mu Microns Mokha
Kuchita zenizeni mu zigawo za AMS 5387 zimachokera ku kusasinthasintha-osati mu kukula kwake, koma mu microstructure, mbiri yotsalira ya kupsinjika maganizo, ndi kukhulupirika pamwamba. Izi zimafuna kusinthidwa kwa tsiku ndi tsiku pa sitepe iliyonse, osati kufufuza kokha pachaka. Zimatanthawuza kukana kutentha kwakukulu chifukwa cha kupatuka kwa kaboni 0.03% - osati chifukwa chololeza, koma chifukwa deta yam'munda ikuwonetsa kuti imathandizira kuvala kwamphamvu m'malo opanda matope.
Ngati polojekiti yanu yotsatira ikudalira magawo a AMS 5387 Stellite, yang'anani kupyola ziphaso. Funsani ma chart enieni. Funsani malipoti a zitsanzo za mayeso kuchokera kumaoda aposachedwa a gawo lanu. Tsimikizirani kuti amaponya * ndi * makina a cobalt alloys - osati kungowagwira. Chifukwa muzovala zapamwamba, zodalirika kwambiri, kusiyana pakati pa "ntchito" ndi "sikulephera kwa zaka 5" kumakhala mwatsatanetsatane palibe mindandanda yamasamba.
