Mainjiniya akamafunikira mphamvu ya fakitale yopangira jakisoni wachitsulo pang'ono pazigawo zosachepera 5 mm zololera ± 0.01 mm, sayamba ndi kusaka kwa Google. Amayamba ndi fanizo lolephera - mphuno ya aloyi ya cobalt yomwe idasweka pakuyezetsa kuthamanga kwa hydraulic, chiboliboli cha pampu chomwe chimachoka mozungulira pambuyo pakutenthedwa, kapena cholozera cha winch center shaft chomwe chinkavala mosagwirizana pambuyo pa maola 200 mumchere wodzaza ndi mchere. Taziwona zonse zitatu - ndikuzikonza zonse osati posintha kulolerana, koma poganiziranso momwe kupanga magawo ang'onoang'ono kumathandizira kusiyana pakati pa zitsulo za ufa ndi kudalirika kwa ntchito.
Kupanga jakisoni wazitsulo yaying'ono sikungokhala "MIM yaying'ono" - kumafunikira kuwongolera kwazitsulo pamlingo wa micron
Kumangirira kowona kwachitsulo kakang'ono kachitsulo (μMIM) kumasiyana ndi MIM wamba m'njira zitatu zosakambitsirana: kugawa kwa tinthu tating'ono kuyenera kukhala pansi pa 5 μm D.90, kuchotsa zomangira kumafuna mbiri yotentha kuti mupewe kung'amba pang'ono pamakoma owonda (<0.3 mm), ndi sintering ayenera kukwaniritsa ≥98.5% kachulukidwe chiphunzitso popanda coarsening njere. Otsatsa ambiri amalemba zigawo kuti "zing'onozing'ono" ngati zili pansi pa 10 g - koma zigawo zenizeni za μMIM zimalemera 0.05-2.5 g ndipo zimakhala ngati mayendedwe ozizirira a 0.15 mm-diameter, makulidwe a 0.08 mm, ndi GD&T callouts pa malo enieni mkati mwa 0.005 mm.
Ichi ndichifukwa chake kusankha kwazinthu sikosankha - ndi lingaliro loyamba la uinjiniya. AMS 5387 cobalt alloy imagwira ntchito pomwe 316 imalephera zosapanga dzimbiri: m'malo othamanga kwambiri, pamayendedwe a 450 ° C, pansi pa kutopa kwapang'onopang'ono kupitilira mizere 10⁷. Koma mawonekedwe ake abwino-grained zimapangitsa kuti asakhululukire panthawi ya debinding. Timagwiritsa ntchito njira ziwiri zosungunulira zosungunulira/kutenthetsa ndi kuyang'anira kutayika kwa nthawi yeniyeni - osati nthawi yokhazikika - chifukwa kusiyana kwa batch-to-batch mu chiwerengero cha kufalikira kwa binder kumakhudza kwambiri kukhulupirika kwa gawo lobiriwira.
Kuphatikizika koyima kumathetsa zomwe kutulutsa kwakunja kumasokonekera
Zolephera zambiri za μMIM zimachokera ku handoffs: zombo zapamadzi za MIM sintered blanks; sitolo yopangira makina ikulimbana ndi kugwira ntchito pazitsulo za 3-mm-diameter; chotenthetsera sichingathe kutengera njira yeniyeni yolumikizira yofunikira pakubalalitsa kwa carbide ya AMS 5387. Timayendetsa masitepe onse atatu pansi pa denga limodzi lovomerezeka la ISO 9001 ku Qingdao - ndipo zimasintha chilichonse.
- Makina a CNC amagwiritsa ntchito mphero za 5-axis zokhala ndi zida zamoyo komanso kufufuza mwatsatanetsatane - kofunikira kwambiri mukayang'anizana ndi 0.2 mm-thick flange ndi ± 0.003 mm flatness
- Kuchiza kutentha kumaphatikizapo vacuum carburizing kwa zigawo zozikidwa pa T800, ndi kupanikizika pang'ono kwa mpweya komwe kumayendetsedwa. <10⁻⁴ mbar kuti muteteze makutidwe ndi okosijeni pamtunda pamizere yovuta
- Kumaliza pamwamba kumagwiritsa ntchito electropolishing yokhala ndi kachulukidwe kamakono ka geometry yakumaloko - palibe ngodya zakhungu, palibe maenje ang'onoang'ono mumayendedwe oyenda
Sitimangokhalira kulolerana. Timakhala ndi zololera * zogwira ntchito: kuuma kwapamtunda Ra ≤ 0.2 μm pankhope zomata, kusasinthika kwapang'onopang'ono pamagawo apakati a 0.5 mm, ndi mbiri yotsalira ya kupsinjika komwe kumatsimikiziridwa kudzera pa XRD diffraction - osati kuuma kwa Rockwell C kokha.
Kupanga-kupanga-kupanga kumayamba fayilo yoyamba ya CAD isanasungidwe
Makasitomala nthawi zambiri amafunsa kuti: "Kodi mungapange izi?" Timayankha kuti: "Inde - koma pokhapokha ngati titasintha ma radius pano, kusuntha malo omwe ali pachipatacho, ndikufotokozeranso malo ena ochezera." Mwachitsanzo, pulagi ya aloyi ya cobalt yokhala ndi ulusi wamkati wa 0.4 mm idalephera mobwerezabwereza mpaka titachoka ku ulusi wamkati-sinter kupita kupanga ulusi panthawi yopangira makina obiriwira - kenako ndikuyika nitriding yotsika m'malo moumitsa wamba. Kusintha kumeneku kunachepetsa kuchuluka kwa zinyalala kuchoka pa 37% mpaka 1.8%.
Timatsimikizira chojambula chilichonse kuti μMIM chitheke - kuyang'ana ngodya zolembera (osachepera 0.5 °), kupewa ngodya zakuthwa zamkati (R ≥ 0.1 mm), kutsimikizira kusintha kwa makulidwe a khoma (palibe> 3: chiŵerengero cha 1), ndi kufananiza mayendedwe a binder kuneneratu mizere yowotcherera m'nyumba zapampu zopyapyala. Ngati GD&T yanu ikuyitanira malo ophatikizika pazidamu zitatu zotalikirana ndi 2 mm, tidzayimitsa - ndikupangira njira yapamalo amodzi yomwe imapereka zotsatira zofananira ndi 40% yotsika mtengo yoyendera.
Kudalirika sikuyezedwa mu ziphaso - kumapangidwa mugawo lililonse
Kutsata si zolemba. Ndi ma code a laser-etched pagawo lililonse, ma cert opangira ma sintering, ndipo malipoti a CMM asungidwa kwa zaka 15 - osati zowunikira, koma ngati malipoti a kasitomala avala pa maola 12,000 ogwirira ntchito, titha kukoka chipika chowongolera kutentha, mbiri ya binder batch, ndi skirini ya optical interfer.ometry kuchokera tsiku limodzi lopanga.
Fakitale yathu yopangira jakisoni wazitsulo yaying'ono imagwiritsa ntchito ma hydraulic OEMs ku Germany omwe amafunikira ma cert a EN 10204 3.1, makontrakitala opangira mafuta ku Texas omwe amafunikira kutsata kwa API Q1, ndi opanga mapampu ku Singapore omwe amafunikira kutsimikizika kwa ASME BPE pamwamba. Zomwe zimawagwirizanitsa si malo - ndikukana kuvomereza "zabwino" pazigawo zomwe zimasindikiza, mita, kapena kuzungulira pansi pa katundu wovuta kwambiri.
Ngati pulojekiti yanu yagawo yaying'ono ikuphatikiza ma aloyi a cobalt, makoma opyapyala olimba, kapena malo ogwirira ntchito omwe amayenera kupulumuka pama media owopsa - yambani ndi machitidwe akuthupi, osati makina. Yambani ndi umwini wa ndondomeko, osati kuthamanga kwa mawu. Yambani ndi mnzanu yemwe amatenga kupatuka kulikonse kwa 0.02 mm ngati kufufuza kwazomwe zimayambitsa, osati kulekerera. Umo ndi momwe kulondola kumakhala kotheka.
