Akatswiri akamatchula magawo a mapampu a hydraulic, ma valve akunyanja, kapena makina opangira ma winchi olemetsa, samangofunika "kutseka mokwanira." Iwo akusowa mwatsatanetsatane makina mbali fakitale kutulutsa komwe ± 0.01 mm kulolerana si bonasi-ndizoyambira. Tawona makasitomala akubweza maulendo atatu a prototypes chifukwa kugwedezeka kwapang'onopang'ono mumilomo ya cobalt alloy kunayambitsa kukokoloka kwa mipando isanakwane. Tawona nthawi yobweretsera ikugwa pomwe kutsitsa sikunalipidwe pakukhazikitsa CNC. Ichi ndichifukwa chake timayang'ana kwambiri zomwe zimagwira ntchito-osati mabulosha, koma kubwereza kwenikweni kwapadziko lapansi pansi pa kupsinjika, kutentha, ndi katundu wozungulira.
Kulondola Kwambiri Padziko Lonse Kumayamba Ndi Kuwongolera Zinthu - Osati Kungosintha
Mashopu ambiri amawona zinthu ngati poyambira. Timachitenga ngati sitepe yoyamba. Ma aloyi a cobalt-nickel monga AMS 5387 ndi T800 sizongovuta kupanga makina - amakhudzidwa ndi zitsulo. Kupatuka kwa 5°C panthawi yothirira madzi kumasintha kagawidwe ka carbide m'malire ambewu. Zosinthazi zimavala kukana m'nyumba za silinda mpaka 37%, kutengera kuyesa kwathu kwamkati mopitilira 12,000. Chifukwa chake timagwirizanitsa mabilu ovomerezeka ndi ogulitsa omwe amapereka kuwunika kwathunthu kwa kutentha-kufikira ku ID ya ng'anjo ya ng'anjo ndi mitengo yoziziritsa - osati ziphaso zokha. Makasitomala akatitumizira chojambula cha pulagi ya aloyi ya cobalt yomwe si yodziwika bwino, tidayika chizindikiro cha kuuma komwe kwafotokozedwa potsutsana ndi piritsi lamphamvu la kutentha komweko. Zotsatira zake? Kuzungulira kosinthidwa kwa kutentha komwe kunapereka HRC 42–44 *ndipo* kunasunga kulimba kopitilira 28 J pa -20°C. Palibe kukonzanso. Osachedwetsa.
Kuphatikizika Koyima Si Buzzword-Ndi Momwe Mumagwirizira Kulekerera Nthawi Zonse
Kuponya + Machining + kumaliza pansi pa denga limodzi kumasintha chilichonse. Ganizirani za injini ya injini ya winch center shaft roller: mchenga-cast mu ductile iron (ASTM A536 Grade ), kenaka yotsirizidwa mpaka ±0.008 mm pa malo amagazini, kenaka amawumitsidwa mpaka 58-62 HRC. Ngati masitepewa achitika kwa ogulitsa atatu, kupotoza kwamafuta kuchokera pakuchepetsa kupsinjika kumatsekeredwa makina asanayambe - ndipo mumathamangitsa geometry m'malo moigwira. Pamalo athu a Qingdao, timapanga makina mkati mwa maola 48 atatulutsa shakeout. Timagwiritsa ntchito macheke a CMM atachita movutikira, kumaliza pang'ono, ndi kumaliza - chilichonse chomangika ku GD&T callouts, osati milingo yadzidzidzi. Panyumba za silinda ya pampu ya pisitoni, timatsimikizira kuti cylindricity * isanakwane* komaliza, osati pambuyo pake. Izo zimatengera kupotoza koyambitsidwa koyambirira. Chaka chatha, izi zinagwira kusintha kwa 0.015 mm taper mu 17% ya magawo oyambirira-kuteteza 220 kg ya zidutswa ndi kukonzanso kwa masabata asanu ndi limodzi.
Ubwino Siuwunikiridwa Mkati-Umamangidwa, Pang'onopang'ono
Sitimachita "kuwunika komaliza." Timatsimikizira pa stage-gate. Zopangira zomwe zikubwera zimapeza kusanthula kwa spectrographic * ndi * kuyesa kwa ultrasonic kwa subsurface porosity - makamaka yofunika kwambiri pazigawo zapampu za AMS 5387 zomwe zimakhudzidwa ndi kutulutsa kwamphamvu kwamadzimadzi. Panthawi ya CNC, ogwiritsa ntchito zida zolembera amavala pachiphaso chilichonse pogwiritsa ntchito miyeso yoyezera laser-osati kuyerekezera kotengera nthawi. Pambuyo pa chithandizo cha kutentha, gawo lililonse limadutsa mapu a microhardness kudutsa magawo atatu. Zigawo zomaliza zimapeza kuyesedwa kogwira ntchito: ma valve opanikizika amayesedwa pa 1.5 × ovotera kuthamanga; cobalt alloy nozzles amakumana ndi kukokoloka koyerekeza ndi 80-micron alumina slurry pa 30 m/s velocity. Ndipo inde-timasunga deta yonse. Osati malipoti okha. Mafayilo a CMM aiwisi, zipika zojambulira zotentha, zosindikiza zolimba. Kutsata sikukhudzana ndi kutsata. Ndizokhudza kudziwa * ndendende * chifukwa chiyani gawo #W-8823 lidakhala mozungulira 0.005 mm pomwe # W-8824 idasunthidwa ndi 0.012 mm - ndikuyikonza kutentha kusanachitike.
Izi Zikutanthauza Chiyani pa Ntchito Yanu Yotsatira
Ngati ntchito yanu ikufuna kulolerana kolimba pa ma superalloys, ma contour ovuta, kapena ntchito yofunika kwambiri - musayambe ndi pempho la mawu. Yambani ndi kuwunika kopanga. Tumizani phukusi lanu la GD&T. Tidzapereka chizindikiro ngati ma angles ojambulidwa akusemphana ndi kuthekera kwa kuponyera, kumene makoma opyapyala amatha kukhala pachiwopsezo pochiza kutentha, kapena pomwe zomaliza zimaposa zomwe zingatheke popanda kugaya kachiwiri. Tathandiza makasitomala aku North America opangira mafuta kuti achepetse nthawi yotsogolera ndi 30% posintha kuchoka pakupanga ndalama zokha kupita ku makina osakanizidwa opangidwa ndi makina osakanizidwa - kukhalabe ndi mphamvu ndikuchotsa machitidwe asanu achiwiri. Kwa European hydraulics OEMs, takwaniritsa zigawo za aloyi za T800 ku certification ya EN 10204 3.2-popanda kuwonjezera mtengo kapena chiopsezo. Kuthekera kwa zida zamakina kumafakitale sikuyezedwa mu kuchuluka kwa spindle kapena malo apansi. Zimayesedwa mumitundu ingati yomwe mumawongolera-ndipo zodabwitsa zochepa zomwe zimapangitsa kuti zigwirizane. Ndiwo muyezo womwe timagwira. Nthawi iliyonse.
