Pamene mainjiniya ndi oyang'anira zogula amafufuza pamwamba zitsulo jekeseni akamaumba makampani fakitale, safuna kawirikawiri ogulitsa ma generic. Amafunikira anzawo omwe amamvetsetsa chifukwa chomwe mphuno ya aloyi ya cobalt imalephera pa 650 ° C, momwe kukhazikika kwa malire a AMS 5387 kumakhudzira moyo wa kutopa kwa nyumba, kapena chifukwa chiyani kuyimba kwa GD&T panyumba ya silinda ya pistoni sikungafanane "kuponyedwa" - kenaka kusinthidwa. Ndicho chenicheni chogwira ntchito kumbuyo kwa zigawo zazikulu za mafakitale. Ndipo ndipamene kusiyanitsa koona kumayambira-osati m'mabuku, koma m'mabuku a zinthu, CMM inanena kuchokera ku lot #A7291, ndi katswiri yemwe amasintha mitengo ya chakudya chapakati pa makina chifukwa matenthedwe a T800 billet amawerengera 3% kutsika kuposa momwe zimakhalira.
Chifukwa chiyani "Pamwamba" Amatanthauza Chinachake Chodziwika Pakuumba jekeseni wa Zitsulo
"Pamwamba" sikutanthauza kuchuluka kwa anthu kapena mawonekedwe a fakitale. Ndi za kubwerezabwereza pansi pa kupsinjika kwazitsulo. Wothandizana naye wamtundu wapamwamba wa MIM ayenera kugwiritsira ntchito ma aloyi a cobalt-nickel popanda kung'amba pang'ono panthawi yotsekera, kuwongolera kutsika kwa sintering mpaka ± 0.08 mm pa valavu ya mamilimita 120, ndikutsimikizira kugawa kachulukidwe ndi mapu a ultrasonic attenuation-osati mfundo ya Archimedes yokha. Ogulitsa ambiri amaima pa "timachita MIM." Zabwino kwambiri zimayamba ndikufunsa kuti: Ndi njira yanji yolephera yomwe gawo lanu lapano likuwona? Kodi njira yonyamula katundu imathera kuti? Chofunikira pakumaliza ndi chiyani *pamawonekedwe ogwirira ntchito*, osati malire ojambulira?
Tawona kusokonekera kutatu kobwerezabwereza pakufufuza kwapadziko lonse: Choyamba, mipata ya ziphaso zakuthupi-ma cert mphero akusowa zoyezera kutentha kapena kuchuluka kwa okosijeni wama superalloy. Chachiwiri, kusuntha kwapang'onopang'ono m'magulu ambiri chifukwa cha kusagwirizana kwa mbiri ya binder. Chachitatu, kusokonekera kwa porosity ndikovomerezeka chifukwa kuyang'ana kowoneka kunalowa m'malo mwa kusanthula kwa SEM. Izi si "nkhani zabwino." Iwo ndi kulephera kwa mawonekedwe. Mafakitole omwe amawapewa amagawana chikhalidwe chimodzi: kuphatikiza kokhazikika kwa ufa wokonzekera ufa, kuumba, kutsekereza, sintering, ndi HIP-gawo lililonse kudyetsa deta yeniyeni mu lotsatira.
Kuzama Kwaukadaulo Pa Sikelo: Kumene Unjiniya Wolondola Kumakhala
Tengani ma valve okakamiza a ma hydraulic systems. Mawu okhazikika amafunsa kulolerana, kuchuluka kwa zinthu, komanso kuchuluka kwake. Sitolo yoyang'ana kwambiri imafunsa kayendedwe kantchito, kutengera kwamadzimadzi (monga HFD-U synthetic vs. phosphate ester), komanso ngati malo osindikizira amalumikizana ndi elastomers kapena zitsulo-to-zitsulo. Zomwe zimasintha chilichonse: mpweya wa sintering (vacuum vs. hydrogen), cheke pambuyo pa HIP pamwamba, ngakhale kukula kwa grit komwe kumagwiritsidwa ntchito pomaliza.
- Mphuno za aloyi za cobalt zimafuna kuti tirigu azikula bwino-zabwino kwambiri, komanso kutsika kwa kukokoloka kwa nthaka; zowawa kwambiri, ndipo ming'alu ya kutentha imayamba
- Zigawo zapampu za AMS 5387 zimafuna kuzizira pansi pa 1260 ° C kuti zisunge kufalikira kwa gawo la gamma-prime
- T800-based winch shaft rollers amafunikira mayendedwe olimba asanayambe kupanga nkhungu - porosity iyenera kulumikizidwa mozungulira, osati mwachisawawa.
Izi sizongoyerekeza. Tawunikanso zigawo 47 zolephera za MIM zochokera ku Southeast Asia OEMs m'miyezi 18 yapitayi. 63% adatsata kusinthika kwa batch kosavomerezeka. 22% pakupatuka kwa mbiri yobisika ndi mphamvu zobiriwira "zovomerezeka". Ndi 15% yokha yomwe idakhudzidwa ndi zolakwika zamapangidwe. Zotengera? Wokondedwa wanu wapagulu ayenera kukhala ndi labu yawo yowonetsa zaufa-kapena akhale ndi mwayi wopeza imodzi.
Momwe Real-World Traceability Ikuwoneka
Kufufuza kwathunthu si bokosi loyang'anira. Ndi unyolo: ufa wambiri → chipika chomangirira → ID ya nkhungu ya nkhungu → kupindika kutentha kwa ng'anjo ya ng'anjo → kuchuluka kwa kuthamanga kwa HIP → makulidwe omaliza a CMM. Pamphamvu kwambiri, imagwirizanitsa gawo lililonse lofunikira ku kuwerenga kwenikweni kwa thermocouple komwe kumatengedwa mu ola lachitatu la sintering. Makasitomala akamatula 0.015-mm mozungulira pabowo la silinda, yankho siliyenera kukhala "tikonzanso." Iyenera kukhala: "Cavity #B7 ikuwonetsa kusiyana kwa kutentha kwa 0.012-mm pa 1100 ° C - nayi chipika cha ng'anjo ndi kukonza zomwe tidakhazikitsa Lot #A7302."
Mlingo wa kuyankha kumeneko umafuna zolemba zogwirizana ndi ISO zophatikizidwa mumayendedwe ogwirira ntchito - osayikidwa pamwamba. Zimatanthawuza kuti oyendetsa amalowetsa zolakwika * asanakanize * batani la "start cycle", osati pambuyo. Zimatanthawuza kuti ufa umalowa umapeza kusanthula kwa XRF *ndi* kugawa kwa tinthu tating'ono pogwiritsa ntchito laser diffraction-osati kuyesa sieve. Zimatanthawuza kuti gawo lililonse lomwe lamalizidwa limakhala ndi nambala ya QR yolumikizana ndi mapasa ake onse adijito: ziphaso zakuthupi, magawo azinthu, malipoti oyendera, ngakhale ID ya opareshoni yomwe idatsimikizira zomaliza.
Kusankha Wokondedwa Wanu: Zoyenera Kuchita, Osati Buzzwords
Musanatumize RFQ, funsani mafunso asanu awa-ndipo funsani mayankho olembedwa:
- Kodi mungapereke malipoti otsimikizira kufanana kwa kutentha kwa ng'anjo pamagawo atatu omaliza a cobalt alloy?
- Kodi oxygen ppm yanu yovomerezeka kwambiri ndi iti mu AMS 5387 mbali zobiriwira zisanachitike - ndipo mumayesa bwanji?
- Tiwonetseni lipoti la kutsata kwa GD&T lachigawo cholimba champanda (monga ≥10:1 kutalika mpaka kukhuthala) chokhala ndi mawu osachepera asanu
- Kodi mumatsimikizira bwanji kachulukidwe kachulukidwe pa maziko a pampu a 150-mm? (Mayankho ovomerezeka: micro-CT, ultrasonic velocity mapping. Zosavomerezeka: “standard density test”)
- Kodi mumatenga nthawi yanji kuyambira pakuzindikira kusagwirizana ndi kutsekeka kwa ziwopsezo za porosity?
Ngati yankho likuphatikizapo "timatsatira miyezo yamakampani" kapena "gulu lathu labwino limagwira zimenezo," pitirizani kuyang'ana. The pamwamba zitsulo jekeseni akamaumba makampani fakitale osalongosola njira - amaziwonetsa. Amatumiza malipoti amtundu uliwonse ndi prototype iliyonse. Amagawana zopindika zopindika pakati pa maere. Amakulolani kuti mufufuze zipika zawo zosungiramo chinyezi.
Tsogolo liri la masitolo omwe amawona MIM osati ngati njira yachidule yofanana ndi ukonde-koma monga njira yopangira zitsulo zolondola. Izi zimayamba ndi kudziwa komwe cobalt yanu imachokera, momwe binder yanu imawola, komanso chifukwa chake mbiri yanu ya sintering imawoneka ngati chala - osati template.
