Kupanga zolekerera kwambiri sikuyamba ndi pulogalamu ya CNC kapena nkhungu yoponya. Zimayamba ndi chisankho: kuyanjana ndi fakitale yokonza makina olondola omwe amasamalira kukhazikika kwazitsulo, kusasunthika kwazitsulo, ndi kudalirika kwa ntchito osati monga zolinga-koma monga zosakambitsirana.
Tawona mapulojekiti ambiri akuyimitsidwa pamlingo wofananira—osati kuchokera ku mapangidwe olakwika, koma chifukwa cha kuthekera kosagwirizana. Makasitomala ku Germany adatitumizira chithunzi chokonzedwanso cha nyumba yapampu ya AMS 5387 cobalt alloy pambuyo poyeserera katatu kwina. Nkhani sinali kulolerana callouts (± 0.01 mm pa zobowola zovuta) kapena pamwamba pamwamba (Ra 0.4 µm). Kunali kupotoza kwa kutentha panthawi ya chithandizo cha kutentha-chosayendetsedwa m'mbuyomu, chosawoneka mpaka kuyesedwa komaliza kwa CMM. Ndi pamene tinazindikira: kulolerana kwakukulu sikungokhudza ziwerengero zolimba. Ndizokhudza kuwongolera kusintha kulikonse komwe kumasuntha manambala amenewo.
Vertical Integration Ndi Mzere Woyamba wa Kulekerera Kulekerera
Othandizira ambiri amapangira kunja, kukonza, kapena kumaliza. Izi zimapanga malo atatu osiyana-ndi mwayi atatu wa microstructural drift, kubwereza zolakwika, kapena ma data olakwika. Pamalo athu ogwirizana ndi ISO ku Qingdao, ma cobalt-nickel castings amachokera ku nkhungu yogulitsa ndalama kupita ku mphero yamitundu yambiri popanda kusiya malo opangira. Timayika makina a silinda mwachindunji kuchokera pazitsulo zofananira - palibe khwekhwe lachiwiri, palibe kusintha kwa data. Pazigawo za pampu ya pisitoni zomwe zimafuna kukhazikika pansi pa 0.008 mm kutalika kwa 300 mm, kupitiliza kumeneko kumachepetsa zolakwika zochulukirapo ndi 60% motsutsana ndi mavenda otsatizana.
Izi sizongoyerekeza. Mu pulojekiti ina yaku North America yopangira mafuta, tidapereka ma valavu 127 - onse mkati mwa ± 0.005 mm m'mimba mwake, zonse zowoneka ndi kutentha kumodzi kwa aloyi ovomerezeka a T800. Bwanji? Chifukwa gulu lathu lothandizira limasintha kutentha kutengera kusanthula kwanthawi yeniyeni yosungunuka, akatswiri athu amakanika amagwiritsa ntchito kuyesa kubweza zida zomwe zidavala zisanafike 0.002 mm, ndipo labu yathu ya metrology imatsimikizira chilichonse motsutsana ndi zofunikira za ASME Y14.5 GD&T-osati miyeso yadzidzidzi.
Katswiri wa Superalloy Amatanthauza Kudziwa Zomwe Zolemba Sizikunena
AMS 5387 sikuti ndi "yovuta kupanga makina." Mlingo wake woumitsa ntchito umakwera pamwamba pa 350 HB. Standard carbide zida fracture; kusokoneza kwa madzi ozizira kumayambitsa zigawo za recast za komweko. Mashopu ena amayankha ndi chakudya chochepa komanso kuchotsa katundu wambiri-ndiye n'kudabwa chifukwa chake mbali zina zimakhala zovuta.
Sititenga ma alloys a cobalt ngati zosiyana. Timawatenga ngati zokhazikika zogwirira ntchito. Laibulale yathu yogwiritsira ntchito zida imaphatikizapo kubowola kwa PCD kwa ma nozzles a T800, mphero zokhala ndi ma cryo kuti zitseke mosalekeza mu mapulagi a AMS 5387, ndi njira zosinthira zomwe zimasunga chip katundu mkati mwa 5% kudutsa makulidwe osiyanasiyana a khoma. Chofunikira kwambiri: timatsimikizira kulimba kwa kutentha kulikonse ndi kukula kwambewu * makina asanayambe * asanayambe. Chifukwa kupatuka kwa 2% mu cobalt kumasintha kukulitsa kwamafuta ndikukwanira kuswa kusokoneza kwa 0.012 mm.
- Magawo a AMS 5387 opangidwa ndi sub-0.003 mm kubwerezabwereza pamagulu a zidutswa 50
- T800 alloy center shaft rollers kukwaniritsa Ra 0.25 µm pamwamba umphumphu popanda post-machining kupukuta
- Cobalt alloy nozzles akudutsa 100% akupanga kuyendera kwa porosity mkati - ngakhale pa 12 mm makulidwe a khoma
Ubwino Siuwunikiridwa Mkati-Umapangidwira
Mafakitale ena amayendera kuyendera nkhani yoyamba. Timayendera koyamba-*material*. Koyilo iliyonse, bala, kapena ingot imafika ndi malipoti athunthu oyeserera. Timasanthula chemistry kudzera mu OES spectroscopy, kutsimikizira microstructure kudzera mu kusanthula magawo, ndi mapu kuuma gradients kudutsa m'magawo osiyanasiyana. Chifukwa chiyani? Chifukwa billet "yotsimikizika" ya AMS 5387 imatha kuwonetsa kuuma kwa 15% kuchokera pamwamba mpaka pachimake - zokwanira kutaya zolosera za moyo wa zida ndikupangitsa kupsinjika kotsalira.
CMM yathu siyiyimitsidwa mchipinda choyendetsedwa ndi nyengo. Imaphatikizidwa mu selo la makina-kuyesa kuzungulira kozungulira * pakati pa * roughing ndi kumaliza kudutsa. Ofananira ndi kuwala amayang'ana kulondola kwa ulusi pamapulagi apagulu pomwe zigawo zikadali zotentha, zomwe zimatengera kutsika kwamafuta. Kuwunika komaliza kumaphatikizapo kuyezetsa kogwira ntchito: ma valve opanikizika amadutsa 1.5 × ovotera hydraulic hold for 30 minutes; ma winch shafts amazungulira pa 2,200 RPM pazitsulo zosinthira.
Kufufuza si bokosi loyang'ana. Ndi unyolo: chiwerengero cha kutentha kwa zinthu → malo oponya → mtundu wa pulogalamu ya CNC → ID ya opareshoni → ID ya lipoti la CMM → malo otumizira. Ngati kasitomala akuwonetsa kusokonezeka, timapanganso njira yonse mkati mwa mphindi 90, osati masiku.
Kudalirika Kweniyeni Kumayamba Pamaso pa PO
"Mungathe kuchita izi?" ndi funso loyamba lolakwika. "Kodi chinthu chomwe chili pachiwopsezo chachikulu ndi chiyani, ndipo timachiyika bwanji * tisanamete zitsulo?" ndiye wolondola. Ichi ndichifukwa chake kuwunika kwathu kwa uinjiniya kumaphatikizapo kutsimikizira kwa GD&T, mayankho opangidwa pazigawo zopyapyala zamakhoma, komanso kayesedwe ka kutentha kwa ma geometries omwe amatha kusokoneza. Timayimitsa zinthu zomwe zingachitike monga kuziziritsa kwapampu poyambira kapena kupatuka kwapampu m'masilinda aatali-silinda njira yoyamba isanapangidwe.
Timapereka ma oda apakati (50-500 pcs) m'masabata 12-18-osati chifukwa tikuchedwa, koma chifukwa timapanikiza chiwopsezo, osati nthawi. Ma Prototypes amatumiza m'masabata 4-6 okhala ndi phukusi lathunthu lowunika. Palibe zodabwitsa. Palibe mipukutu yokonzanso. Zigawo zomwe zimagwira ntchito monga momwe zafotokozedwera, munthawi yake, m'misika yapadziko lonse lapansi - kuchokera ku ma hydraulic OEMs ku Wisconsin mpaka zophatikizira pampu zakunyanja ku Singapore.
Kwa mainjiniya omwe amatchula magawo omwe ± 0.005 mm amatanthauza kusiyana pakati pa kukhulupirika kwa chisindikizo ndi kulephera koopsa, kuyanjana ndi fakitale yopangira makina olondola kumatanthauza kusankha kuwongolera kusagwirizana. Zimatanthawuza kudalira kuti cobalt alloy sikuti amangopangidwa - ndi bwino. Kulekerera kumeneko sikuthamangitsidwa-kumangiriridwa. Kuti gawo lirilonse limafotokoza nkhani yofanana: kutsimikizika kwa dimensional, kukhulupirika kwa zinthu, kukonzekera ntchito.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pa mphambano imeneyo-pomwe kupangidwa kwa superalloy kumayenderana bwino ndi mafakitale. Ntchito yawo imatsimikizira kuti kulekerera kwakukulu sikumatanthauzidwa ndi zida zokha. Zimatanthauzidwa ndi zomwe zimachitika pakati pa satifiketi yazinthu zopangira ndi lipoti lomaliza loyendera. Ndipo ndipamene kudalirika kwenikweni kumayambira.
