Pamene mainjiniya ndi oyang'anira zogula amafufuza a MIM fakitale okhoza kuperekera zida zachitsulo zolondola kwambiri pansi pazovuta kwambiri, samakonda kuyamba ndi mayina amtundu. Amayamba ndi vuto: mphuno ya cobalt-alloy ikulephera pa 1200 psi, pompu ya pistoni ikugwedezeka pambuyo pa kutentha kwa kutentha, kapena shaft yopangira makina yomwe imakanidwa panthawi yowunika-katatu. Taziwona zonse zitatu. Ndipo nthawi iliyonse, chifukwa chake sichinali kupanga bwino. Kunali kusagwirizana pakati pa khalidwe lakuthupi, kayendetsedwe ka ndondomeko, ndi kutsimikizira ntchito.
Chifukwa chiyani "MIM Factory" Yokha Siyokwanira-Makamaka Magawo Ofunika Kwambiri
Metal Injection Molding (MIM) imapambana pazovuta za net-shape-koma pokhapokha zitaphatikizidwa ndi zitsulo zakuya. Otsatsa ambiri amadzilemba okha a MIM fakitale pamene mukutulutsa sintering, kudumpha kutsatiridwa kwa batch, kapena kuchitira AMS 5387 cobalt alloy ngati standard 316 zosapanga dzimbiri. Ndiko kumene kulondola kumathera ndipo chiopsezo chimayambira. Zolephera zenizeni zomwe talemba zikuphatikizapo:
- Kuphulika kwapang'onopang'ono mumipando ya ma valve yochokera ku T800 pambuyo pa matenthedwe 400 - kutsatiridwa ndi chithunzithunzi chosagwirizana cha kaboni panthawi yomanga.
- Zolakwa za GD&T zosungiramo ma silinda okhala ndi ma axis angapo - chifukwa cha chipukuta misozi chosakonzedwa mu MIM feedstock
- Kuyika pamwamba pa mapulagi a pampu osakhazikika-olumikizidwa ndi phulusa lotsalira lomwe silinachotsedwe pamaso pa HIP
Izi sizinthu zongoyerekeza. Ndizotsatira zobwerezabwereza MIM ikatengedwa ngati njira yodziyimira yokha-osati ngati gawo limodzi pamayendedwe omangika omangika-omaliza.
Kuphatikizika Koyima Ndikofunikira Kosayankhulidwa Kwa Kulondola
Simungathe kutsimikizira ± 0.01 mm kulolerana pa gawo la AMS 5387 cobalt alloy ngati wothandizira wanu wa MIM sakuwongolera kukula kwambewu ya alloy * asanabadwe * jekeseni-kapena kutsimikizira mphamvu zolimba * pambuyo * HIP koma * CNC isanamalize. Ichi ndichifukwa chake ochita mwamphamvu kwambiri amagwira ntchito m'magawo atatu nthawi imodzi: zitsulo za ufa, makina olondola, ndi kutsimikizira ntchito.
Mwachitsanzo, ma valve opanikizika omwe amapangidwira ma hydraulic system amafunikira zambiri kuposa kulekerera zolimba. Amafunikira kuuma kosasinthika pamalo okwerera-ndipo zomwe zimangotuluka pomwe magawo a sintering asinthidwa munthawi yeniyeni kutengera chidziwitso cha ng'anjo ya ng'anjo, kenako amatsimikiziridwa motsutsana ndi kuwerengera kwa Rockwell C pambuyo pa Machining. Kuyankha uku sikungatheke popanda nkhokwe zogawana zida, ma protocol oyendera ogwirizana, ndi mainjiniya omwe amalankhula bwino MIM ndi GD&T.
Tasanthula malo opitilira 17 omwe amati ali ndi kuthekera kwa MIM. Anayi okha ndi omwe adapambana mayeso athu ogwira ntchito: kukhazikitsa gawolo, kukanikiza ku spec, kuthamanga ma 500, kenako kuyezanso ma diameter ovuta. Mmodzi adapereka zero drift nthawi zonse. Chinsinsi chawo? Palibe ma handoffs. Ufa wosaphika umalowa pakhomo limodzi. Ziwalo zomalizidwa, zotsatirika, zoyesedwa bwino zimatulukanso—kusintha komweko, labu yofananira ya metrology, lolemba labwino lomwelo.
Kuwerengera Kwamakina Kwaukadaulo Wazinthu -Nthawi Zonse
A MIM fakitale yokhala ndi ng'anjo za 12 sizitanthauza pang'ono ngati ilibe chidziwitso cholembedwa ndi cobalt-nickel superalloys pansi pa makulidwe a khoma la 0.5 mm-kapena ngati gulu lake silinawerengetsere ma feedstock rheology kwa T800's high-density sintering curve. Ukadaulo weniweni umawonekera m'njira zobisika:
- Kugwiritsa ntchito ma spectroscopy opangidwa ndi optical emission-osati satifiketi ya kusanthula-kutsimikizira kuchuluka kwa Co/Ni/Cr *pagulu*
- Kuyika ma laser-induced breakdown spectroscopy (LIBS) pazigawo zobiriwira kuti agwire tsankho musanamange
- Kuthamanga koyezetsa kowonjezera kwamafuta (CTE) kolumikizana pakati pa zigawo za as-sintered ndi HIP'd pagawo lililonse.
Izi siziri zovuta zamaphunziro. Ndizomwe zimalepheretsa gawo la mpope la $ 2,400 AMS 5387 kuti lisaphwanyike pa msonkhano womaliza chifukwa coefficient yake imasiyana ndi nyumba yachitsulo ndi 0.3 ppm/°C.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito motere-osati ngati wogulitsa, koma monga chowonjezera cha gulu laukadaulo la kasitomala. Malo ake ogwirizana ndi ISO amayang'anira chilichonse kuyambira pakuyika zitsulo zopangira zitsulo mpaka mphero zisanu za mphuno za cobalt - zonse pansi pa denga limodzi, zowoneka bwino kuchokera pa satifiketi ya mphero mpaka lipoti lomaliza la CMM. Pamene wogula mafuta aku North America amafunikira ma valve opanikizika 37 m'masabata 11-iliyonse imafuna kutsata kwa AMS 5387, HIP, ndi kumaliza pamwamba Ra ≤0.4 µm-gululo lidatsimikizira ma callout a GD&T *asanagwiritse ntchito zida, adayesa mayeso owononga mutu woyamba *panthawi ya* sintering, ndikutumiza malipoti odzaza ndi kutentha. Zero kukonzanso. Zero kuchedwa.
Kusankha Mnzanu Wotsatira wa MIM—Funsani Mafunso Atatu Awa
Osafunsa "Kodi mumachita MIM?" Funsani m'malo mwake:
- "Ndiwonetseni maere anu atatu omaliza a AMS 5387, kuphatikiza zipika zamlengalenga, ma chart a HIP cycle, ndi mamapu a post-HIP microhardness." Ngati akayikira, chokanipo.
- "Kodi mumatsimikizira bwanji chipukuta misozi cha ma geometries ovuta amkati - ngati njira yoyatsira 0.8 mm mkati mwa maziko a mpope?" Mayankho okhudza kayeseleledwe ka CAD kokha—osati kuyesa nkhungu mwachidziwitso—ndi mbendera zofiira.
- "Kodi mumayendetsa nthawi yayitali bwanji pazigawo za T800 popanda kusuntha mozungulira? Othandizana nawo bwino amatsata zomwezo tsiku lililonse.
Kulondola kwenikweni sikutheka mu sitepe imodzi. Ndilo chotulukapo cha kubwereza koyenera pazinthu zonse, kachitidwe, ndi muyeso. A MIM fakitale zomwe zimagwira pulagi iliyonse ya cobalt, nyumba ya pistoni iliyonse, shaft iliyonse ngati kachitidwe - osati gawo - imapeza chidaliro chifukwa cha kusasinthika, osati zonena.
Yang'anani omwe amatumiza ndi zochulukirapo kuposa magawo. Amatumiza ndi chidaliro - mothandizidwa ndi deta, kutsata, komanso kulekerera zero pazongoganiza.
