Mainjiniya akamatchula magawo a aloyi opangidwa ndi faifi, samangosankha zinthu - akudzipereka kuti agwire ntchito mopanikizika, kutentha, komanso dzimbiri. Kusakwanira kumodzi kokha pakukhazikika kapena mawonekedwe ang'onoang'ono kumatha kugwera pakulephera kwa pampu, kutayikira kwa valve, kapena kutsika kosakonzekera m'ma hydraulic system kapena zida zamafuta. Ndicho chifukwa chake kufufuza kuchokera ku a fakitale ya fakitale ya aloyi ya nickel sizili za mtengo wokha-ndi za kuyankha kwazitsulo, chilango cha ndondomeko, ndi kutsimikiziridwa kuyankha ku zochitika zenizeni zapadziko lapansi.
Chifukwa chiyani AMS 5387 ndi T800 Amafuna Zambiri Kuposa Machining Wamba
Tawona ma projekiti ambiri akuyimitsidwa pamlingo wofananira - osati chifukwa cha zolakwika zamapangidwe, koma chifukwa wogulitsa alibe luso lapamwamba la cobalt-nickel superalloys. AMS 5387 cobalt alloy 6 ndi zida zochokera ku T800 sizikhala ngati 316 zosapanga dzimbiri. Amagwira ntchito molimba mtima. Awo matenthedwe madutsidwe ndi otsika. Zida zodulira zimavala mwachangu pokhapokha mitengo ya chakudya, kutumiza koziziritsa kukhosi, ndi geometry ya zida zikugwirizana ndendende ndi kuuma kwa batch ndi kapangidwe kambewu.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Nozzle iliyonse ya AMS 5387 kapena T800 center shaft roller imayamba ndi certification ya raw material traceability-osati ma cert mphero, komanso mbiri ya kutentha kwa mlingo wambiri wokhudzana ndi kuponya mitengo. Timayesa kusanthula kwa spectrographic komwe kukubwera pa coil kapena ingot iliyonse. Ngati mpweya wa carbon ukuyenda ± 0.02%, timayika kwaokha ndikuyesanso tisanalowetse mu CNC kapena mizere yopangira ndalama. Izi si overkill. Ndimomwe timagwirira ± 0.005 mm tolerances pa 200 mm piston pump silinda nyumba zogwirira ntchito pa bar 420.
Kuphatikiza kwathu koyima kumapangitsa kusiyana: kuponyera, kukonza makina, ndi kumaliza kumachitika pansi pa denga limodzi logwirizana ndi ISO. Palibe ma handoffs amatanthauza kuti palibe kusuntha kwapakati pakati pa as-cast geometry ndi kutsata komaliza kwa GD&T. Timatchinjiriza mchenga wobiriwira kapena malo opanda kanthu - palibe chowonjezera chomwe chimabweretsa cholakwika. Kwa ma geometri osakhala wamba, monga ma asymmetric winch center shaft rollers okhala ndi ma spline ophatikizika ndi zolemba zonyamula, timagwiritsa ntchito mphero ya 5-axis nthawi imodzi yokhala ndi kafukufuku wa laser kuti titsimikizire kukhulupirika kwa contour tisanadule.
Kumene "Mwambo" Kutanthawuza Mgwirizano Waumisiri-Osati Kumasulira kwa CAD kokha
Opanga ena amatengera madongosolo achikhalidwe ngati zopatuka pamakatalogu wamba. Timawatenga ngati njira zothetsera mavuto. Pamene kampani ya ku Europe yapampu ya OEM idatitumizira chojambula cha pulagi ya AMS 5387 yokhala ndi ma radiyo atatu olowera mkati ndi 0.8 µm Ra pamwamba pakufunika, funso lathu loyamba silinali "Kodi mungavomereze mawuwo?" Anali "Kodi njira yolephera yomwe mukuyesera kupewa ndi iti?"
Zinapezeka kuti kukokoloka kwa cavitation pamphambano ya radius kudapangitsa kulephera kwamunda pambuyo pa maola 1,200. Chifukwa chake tidakonza ma electropolish a post-machining - otsimikiziridwa ndi kujambula kwa SEM - kuti achotse misonzi yaying'ono yosiyidwa ndikupera wamba. Tidaperekanso malingaliro osintha njira yochizira kutentha: yankho la anneal *asanayambe* kukonza komaliza, kenako kukalamba *pambuyo pa*, kuti atseke mwamphamvu popanda kusokoneza machinability. Gawoli linadutsa kuyesa kwa moyo kwa maola 3,500. Chotsatiracho chinabwera chifukwa cha chidziwitso cha dera - osati luso lokha.
Mulingo uwu wakuchitapo kanthu umagwira ntchito chifukwa gulu lathu limaphatikizapo mainjiniya ogwiritsira ntchito omwe athandizira ma hydraulic system amamanga ku North America ndi Southeast Asia. Amalankhula GD&T bwino. Amawonetsa zoopsa zomwe zingapangidwe msanga, monga kufotokozera utali wa 0.2 mm pabowo lakuzama lakhungu la 12 mm momwe chida chimalepheretsa kutuluka kwa chip. Sitikuyembekezera kuti gawo loyamba lokanidwa liyambe kukambirana.
Kuwongolera Kwabwino Zomwe Siziyima pa Lipoti la CMM
Lipoti la CMM limatsimikizira kukula kwake. Izo sizimatsimikizira kukhulupirika kwa ntchito. Chifukwa chake ndondomeko yathu yoyendera imapita mozama: kutsimikizira kwazinthu zomwe zikubwera, kulimba kwa mapu pa mfundo zitatu pakuponyedwa, kuyang'ana kwathunthu kwa mawonekedwe osindikizira ofunikira, ndikuyesa komaliza kogwira ntchito - kuphatikiza kuwunika kwa kuwonongeka kwa ma valve onse mpaka mipiringidzo 600.
- Timasunga kutsata kwathunthu: nambala ya kutentha, machusi oponyera, mtundu wa pulogalamu ya CNC, ID ya ogwiritsa ntchito, ndi zipika zamasankho pa gage iliyonse yomwe imagwiritsidwa ntchito.
- Timatsimikizira kumaliza kwapamwamba ndi ma profilometer onse ndi kufananitsa kowoneka motsutsana ndi miyezo ya ASTM B487
- Timachita kuyezetsa kupopera mchere (ASTM B117) pazigawo zomalizidwa pomwe kukana kwa dzimbiri kumakhala kofunikira kwambiri.
Palibe zombo zamagulu zopanda mbiri yoyendera - ndipo palibe mbiri yomwe imamveka pokhapokha ngati cheke chilichonse chikugwirizana ndi zomwe kasitomala amavomereza, osati malire amkati okha.
Kudalirika Sizonena - Kumayesedwa mu Kusasinthika kwa Kutumiza
Kupanga kodalirika kumatanthawuza kugunda masiku omaliza popanda kudzipereka mwatsatanetsatane. Tasunga> 97% pa nthawi yobweretsera pakupanga kwapakatikati kwa miyezi ya 27 yapitayi-osati mwa nthawi zotsogola, koma poyika njira zowongoka pakukonza zozungulira, kukonza ma CNC, ndi kasamalidwe ka mizere ya kutentha. Madongosolo a prototype amadutsa m'maselo odzipereka odzipereka. Kupanga kumayendetsa zidziwitso zongowonjezeranso zinthu zomwe zimagwirizanitsidwa ndi nthawi yotsogolera ogulitsa. Palibe "ndalama zothamangira" pantchito zofulumira - zokambirana zowonekera bwino zamalonda: "Titha kupereka m'masiku 18 ngati tisintha dongosolo la chithandizo cha kutentha. Kapena m'masiku 22 ndikukalamba kwathunthu malinga ndi AMS spec."
Kuyang'ana m'tsogolo, tikukulitsa R&D pakupanga makina osakanizidwa-makamaka kuyika ndalama zofananira ndi mawonekedwe a nickel zovuta za aloyi, kutsatiridwa ndi kuchotsedwa kwamitengo ya CNC yolondola kwambiri. Zotsatira zoyamba zikuwonetsa 32% zowononga zinthu zocheperako komanso 20% mwachangu kutulutsa kwazinthu monga ma valve othamanga amitundu yambiri. Cholinga chathu sikungokwaniritsa zomwe zamasiku ano. Ndizothandiza makasitomala kupanga machitidwe a mawa ndi kulolerana kolimba, kupanikizika kwakukulu, komanso nthawi yayitali yautumiki.
Ngati pulojekiti yanu yotsatira ikukhudzana ndi zida za nickel-based alloy-makamaka AMS 5387, T800, kapena magiredi ena apamwamba a cobalt-nickel-yambani ndi khalidwe lakuthupi, osati zojambula zokha. Sankhani mnzanu amene dongosolo lake likufanana ndi zomwe mukuyembekezera. Sankhani kudalirika komwe kumapangidwa mu sitepe iliyonse-osalonjezedwa mu pepala la malonda.
