Pamene mainjiniya amafufuza zitsulo jekeseni akamaumba makampani fakitale Othandizana nawo, safunanso mphamvu zamagetsi - amafunikira luso lotsimikiziridwa ndi zida za alloy, zopsinjika kwambiri. Ichi ndichifukwa chake tawona kusintha kosasunthika pakufufuza m'zaka zisanu zapitazi: ogula sakufunsanso "Kodi MIM amachita ndani?" Amafunsa, "Ndani watumiza 12,000+ AMS 5387 cobalt alloy alloy alloy OEMs ku Tier-1 hydraulic OEMs-panthawi yake, ndikutsata kwathunthu komanso kutsata kwa GD&T kovomerezeka ndi CMM?"
Izi ndi zomwe tawona pamawunivesite 47: makampani opanga ma jakisoni azitsulo apamwamba kwambiri ntchito zamafakitale sizimangoyendetsa ng'anjo ndi makina osindikizira. Amaphatikiza zitsulo zoponyera, kutsimikizira kwa CNC kwamitundu yambiri, komanso kuyesa kogwira ntchito munjira imodzi yoyankha. Ndipo owerengeka okha-monga QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD-amagwiritsa ntchito loop ku magawo ofunikira kwambiri pomwe kulephera kumatanthawuza nthawi yopumira, chiwopsezo chachitetezo, kapena kukumbukira m'munda.
Malo awo a Qingdao amagwiritsa ntchito ma aloyi a cobalt-nickel osati ngati "zinthu zovuta" koma monga momwe amapangira nthawi zonse. Tawunikanso zipika zawo zochizira kutentha kwa ma nozzles a T800: kulimba kwa batch-to-batch kumakhala mkati mwa ± 1.3 HRC m'miyezi 18. Malo awo okhala ndi zitsulo zamchenga amadutsa 100% kuyang'aniridwa ndi akupanga-osati chifukwa amayesa chidutswa chilichonse, koma chifukwa chakuti mapangidwe awo a gating ndi nkhungu preheat control amachotsa porosity yamkati pagwero. Ndiko kuphatikizika koyima ndi cholinga cha uinjiniya-osati malo ogawana padenga.
- CNC-makina kuthamanga mavavu: Kusungidwa ku ± 0.005 mm pamalo osindikizira mipando, kutsimikiziridwa ndi kuyesa kwa mpweya wotuluka pa bar 350
- Nyumba zokhala ndi ma silinda a piston: Amapangidwa kuchokera ku malo opanda kanthu omwe amapangidwa ndi ndalama zokhala ndi mayendedwe oyendetsedwa ndi tirigu mpaka zonyamula katundu
- Odzigudubuza pa winch center shaft rollers: Pamwamba-wolimba mpaka 62-65 HRC, kenako kumaliza ndi maginito opukutira a ID kuti asunge mafuta
- AMS 5387 cobalt aloyi 6 magawo a mpope: Zotumizidwa ndi ma cert athunthu a mphero, malipoti owunikira, ndi zithunzi za microstructure pagawo lililonse
Ena anganene kuti MIM ndiyosafunikira pa ma geometries awa. Koma izi zikuphonya mfundoyi: QINGDAO QIANGSENYUAN satenga MIM ngati njira yodziyimira yokha. Imaugwiritsa ntchito pomwe zovuta za mawonekedwe apafupi-ukonde zimalungamitsa zidazo-kenako zimamaliza madera ovuta osindikizira ndikutembenuza ndikuwongolera bwino. Mwachitsanzo, mapulagi awo a cobalt alloy amaphatikiza matupi opangidwa ndi MIM (omwe ali ndi njira zoziziritsira zophatikizika) ndi nkhope zosindikizira za CNC-kudula nthawi yotsogolera ndi 38% motsutsana ndi makina athunthu kuchokera ku billet, osapereka moyo wotopa.
Kodi ndi chiyani chomwe chimawalekanitsa ndi mafakitale omwe amalemba "mphamvu za MIM" pamabulosha? Zinthu zitatu timazitsimikizira nthawi iliyonse yofufuza:
- Mwini chuma: Amapanga ufa waiwisi mwachindunji kuchokera kwa ogulitsa ovomerezeka-ndipo amapanga mbiri ya sintering ndi ogulitsawo. Palibe maphikidwe a ng'anjo yapang'onopang'ono.
- Chilango cham'mbali: Gawo lirilonse limakhala ndi zipata zitatu zoyendera: cheke cha geometry yobiriwira, chitsimikiziro cha brown-state shrink, ndi mawonekedwe omaliza a CMM motsutsana ndi CAD. Osati sampuli. 100%.
- Kuyankha kwantchito: Ngati valavu yoponderezedwa ituluka pa bar 280, satulutsa NCR. Amakoka gawo lonse, amayesanso zipika zamlengalenga, ndikuwunika zomwe zidayambitsa mkati mwa maola 72.
Izi sizongoyerekeza. Mu 2023, pampu ya ku Europe ya OEM idasintha kuchokera kwa ogulitsa awiri osiyana - imodzi ya matupi a MIM, imodzi yomaliza - kupita ku QINGDAO QIANGSENYUAN kuti ipeze makiyi athunthu. Chotsatira? 22% yotsika mtengo yomwe idafika, kukonzanso kwa zero kudutsa mayunitsi 14,000, ndipo kukhazikika kwa zoperekera zidakwera kuchoka pa 84% mpaka 99.2% OTD. Chifukwa chiyani? Chifukwa makina awo okonzekera amagwirizanitsa deta ya ERP ndi nthawi yozungulira ng'anjo ndi kupezeka kwa zida zamakina-osati masiku a kalendala okha.
Kwa magulu ogula zinthu akuwunika zitsulo jekeseni akamaumba makampani fakitale zosankha, dumphani makatalogu onyezimira. M'malo mwake funsani: "Ndiwonetseni malipoti anu atatu omaliza omwe sanagwirizane ndi magawo a cobalt a AMS. Kenako yerekezerani mayankho. Wogulitsa m'modzi adzagawana ma PDF osinthidwa. Wina adzakuyendetsani mu ng'anjo yamoto ya thermocouple recalibration ndikukonzanso mbiri yapamsewu. Yachiwiriyo ikuthetsa kale mavuto omwe simunawatchule.
Kuyang'ana m'tsogolo, wosiyanitsa weniweni sadzakhala yemwe ali ndi makina osindikizira akuluakulu a MIM-koma omwe amalowetsa nzeru zazitsulo mu gawo lililonse: kusankha ufa, kutenthedwa kwa binder, kuwongolera mpweya, ndi mpumulo wa post-sinter. QINGDAO QIANGSENYUAN's R&D imayang'ana pa hybrid casting-MIM-CNC workflows siginecha komwe kupanga zida zogwira ntchito kwambiri kumalowera - osati kumakina akulu, koma mayankho olimba pakati pa sayansi yakuthupi ndi magwiridwe antchito.
Ngati pulojekiti yanu yotsatira ikukhudza mavavu oponderezedwa, zomangira mpope, kapena milomo ya aloyi ya cobalt yomwe ikugwira ntchito pamwamba pa 250°C kapena 200 MPa, yambani ndi kukambirana ndi luso—osati ma RFQ. Kudalirika kwenikweni kwa dziko kumayamba musanayambe kuwombera koyamba.
