Pamene mainjiniya amafotokozera a aloyi bushing fakitale, sikuti amangoyitanitsa magawo - akusankha bwenzi lomwe lingathe kupirira ± 0.005 mm pansi pa 300 MPa hydraulic loads, kukana kuphulika kwa cobalt-alloy-on-steel interfaces, ndikupereka microstructure yobwerezabwereza pamagulu a zidutswa 500. Ndicho chenicheni cha ntchito-osati chinenero cha malonda.
Tapanga ma AMS 5387 cobalt alloy bushings pamapope akunyanja pomwe vuto limodzi lidayambitsa vuto la $210,000. Tawona makasitomala akukana T800-based center shaft rollers pambuyo polephera kumunda-osati chifukwa cha kutopa, koma chifukwa cha kusagwirizana kwa carbide kubalalitsidwa mu as-cast microstructure. Izi sizowopsa zongoyerekeza. Iwo ndi osinthika tsiku ndi tsiku pakupanga chigawo chachikulu cha alloy.
Kulondola Kumayamba Ndi Kuwongolera Zinthu - Osati Kungokanika
Zolephera zambiri za alloy bushing zimayambira kale njira yoyamba yopangira zida: kusagwirizana kwazinthu zopangira, mbiri yakale ya kutentha kosatsimikizika, kapena kusiyanasiyana kwa batch-to-batch pakuuma kolimba. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ingot iliyonse ya cobalt-nickel imafika ndi malipoti oyesa mphero-ndipo malo aliwonse amatsimikiziridwa mowonekera atalandira. Sitivomereza "zinthu zovomerezeka" mwachiwonekere. Timazitsimikizira.
Kulangidwa kumeneku ndikofunikira chifukwa ma bushings mu nyumba za silinda za pampu ya pisitoni zimapirira kukweza mozungulira ndikusunga chisindikizo motsutsana ndi slurry yamadzimadzi abrasive. Kupatuka kwa 2 HRC pakuwuma kwapamwamba kumasintha moyo ndi 40% pakuyezetsa kwenikweni. Zitsulo zathu zachitsulo zoponyera mchenga zimagwiritsa ntchito mitengo yoziziritsa yoyendetsedwa kuti ikwaniritse kugawa kofanana kwa ma graphite nodule - kofunikira pakugwedezeka kwamphamvu pamakina owongolera magalimoto. Palibe njira zazifupi. Palibe zongoganizira.
Timapereka AMS 5387 pa ASTM A494, T800 pa AMS 5719, ndi zitsulo zosapanga dzimbiri ku ASTM A743. Koma chizindikiritso chokha sichimatsimikizira kugwira ntchito. Timathandizana mwachindunji ndi metallurgists kwa ogulitsa zinthu kuti tisinthe magawo olimba-kuwonetsetsa kuti carbide morphology ikhale yoyenera pamtundu uliwonse wazovuta za pulogalamuyo.
Kuphatikizika Koyima Si Buzzword-Ndi Inshuwaransi Yamagawo
Mafakitole ena akuponya kunja, kenako makina, kenako amatumiza magawo kuti azitha kutentha. Chiwopsezo chilichonse chimabweretsa zolakwika pakusunga. Pamalo athu ogwirizana ndi ISO ku Qingdao, gulu lomwelo limayang'anira ntchito zandalama, makina a CNC amitundu isanu, chithandizo cha kutentha kwa vacuum, ndi kuyendera komaliza kwa CMM. Chotsatira? Mphuno ya aloyi ya cobalt yomwe tidapereka kwa wothandizira mafuta aku North America idakhala ndi malo enieni mkati mwa 0.012 mm kudutsa ma callout 12 ovuta a GD&T - osakonzanso.
Izi sizingatheke popanda kugwirizana kolimba kwa ndondomeko. Tikayika makina a valve oponderezedwa kuchokera ku mphete ya cobalt ya centrifugally, timawerengera mpumulo wotsalira panthawi yamavuto. Tikamaliza kumanga maziko a pampu yachitsulo chosapanga dzimbiri, timakhala ndi nthawi yopera pamwamba kuti titsatire njira yothetsera vutoli - kupewa kupotoza komwe kungawononge gawolo poyang'anitsitsa.
Kuthekera kwathu kumayambira pamagulu onse anayi oyambira: matabwa opangidwa ndi CNC (kuphatikiza ma geometries osakhala wamba), zida za cobalt-nickel alloy (AMS 5387, T800), zoponya zachitsulo, ndi zitsulo / zitsulo zosapanga dzimbiri. Koma chomwe chimatifotokozera ndi momwe njirazi zimagwirira ntchito - osati momwe aliyense amagwirira ntchito payekhapayekha.
Kutsimikizika Kwapadziko Lonse Kumenya Zolemba Papepala
Makasitomala amafunsa: "Kodi mutha kukhala ndi 0.003 mm kuzungulira pa 120 mm OD cobalt bushing?" Inde—koma kokha ngati tilamulira njira yonse yotentha. Timayezera kusokonekera pakatha kutentha kulikonse pogwiritsa ntchito makina owonera ma contour scanner, osati kungoyang'ana pambuyo pa makina a CMM. Tapanga mapu a momwe kusintha kozungulira kwa 5 ° C pomaliza kumakhudzira kukhazikika kwa ma aloyi a nickel apamwamba. Timasintha kutentha kozizira moyenerera.
Sitimatumiza magawo potengera kuvomereza kwa nkhani yoyamba yokha. Kupanga kulikonse kumaphatikizapo kutsimikizika kwa magwiridwe antchito: kuyezetsa kukanikiza mpaka 1.5 × kukakamizidwa kugwira ntchito, kutsimikizira kuuma kwa ISO 4287, komanso kuyang'anira kowoneka pansi pa 10 × kukulitsa kwa ming'alu yaying'ono. Kutsatiridwa sikosankha - kumaphatikizidwa. Chitsamba chilichonse chimakhala ndi ID yokhala ndi laser yolumikizidwa ndi zinthu zake, piritsi la kutentha, komanso lipoti loyendera.
Kwa ma OEMs a hydraulic system, izi zikutanthauza kuti palibe zodabwitsa pamsonkhano. Kwa omanganso mapampu ku Southeast Asia, zimatanthawuza nthawi zotsogola zodziwikiratu, ngakhale kwa ma geometries okhazikika ngati tchire lokhala ndi makulidwe asymmetric.
Kusankha a aloyi bushing fakitale amatanthauza kusankha yemwe ali ndi chiopsezo pamene ntchito ikulephera pansi pa katundu. Zimatanthawuza kudziwa ngati wopereka wanu akumvetsa chifukwa chake cobalt alloy 6 imachita mosiyana ndi Inconel 718 panthawi yodula-kapena momwe mchenga wopangira mchenga umakhudzira kuyambitsa kutopa mu ma roller a winch center shaft. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Kumvetsetsa kumeneku kumakhala pansi pashopu yathu - osati malo athu ogulitsa okha. Timapangira ntchito zofunika kwambiri, osati manambala amndandanda. Ndipo timatsimikizira, gawo limodzi lovomerezeka panthawi imodzi.
