Mainjiniya akamatchula zitsulo zosapanga dzimbiri kuti zikhale zolondola kwambiri, zofunikira kwambiri - lingalirani ma valve opanikizika mu makina opangira ma hydraulic kapena ma piston pump cylinder housings - amafunikira zambiri kuposa kukana dzimbiri. Amafunikira kukhazikika kwapang'onopang'ono panjinga yotentha, kukhazikika kwapang'onopang'ono pambuyo pa sintering, ndi kumaliza kwapamtunda komwe kumapulumuka pa media media. Ndiko kumene wodzipereka zitsulo jekeseni akamaumba zosapanga dzimbiri fakitale amakhala wosakambitsirana—osati monga wopereka, koma ngati wothandizana nawo.
Chifukwa Chake Chitsulo Chosapanga chitsulo cha MIM Imafunikira Kuphatikizika Koyima—Osati Zida Zokha
Tawona ma projekiti ambiri akuyimitsidwa pamlingo wofananira chifukwa shopu ya MIM imagwira ntchito zosakaniza ndi kubweza, koma kutumizidwa kunja kwa wogwiritsa ntchito ng'anjo wamba. Zitsulo zosapanga dzimbiri monga 17-4 PH kapena 316L zimagwira ntchito mosadziwikiratu popanda kuwongolera mwamphamvu kupanikizika pang'ono kwa okosijeni, kuchuluka kwa ma rampu, komanso nthawi yogwira panthawi ya sintering. Pa QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mayendedwe onse a MIM-kuchokera ku feedstock formulation yokhala ndi certified stainless steel powder (ASTM A985-compliant), kudzera pa zosungunulira ndi zotenthetsera, mpaka vacuum-sintering mu ng'anjo zovomerezeka za ISO 9001-zikuphedwa padenga limodzi. Palibe ma handoffs. Palibe kusiyana kwa batch-to-batch pakukula kwambewu. Palibe zodabwitsa pamene ma callout a GD&T amafuna ± 0.02 mm pazinthu zamakhoma woonda zosakwana 1.2 mm.
Kuphatikiza uku ndikofunikira kwambiri pamene geometry ikukumana ndi ntchito. Winch center shaft roller ya magalimoto a engineering imafuna kulimba ≥38 HRC *ndi* kuuma kwapamtunda kwa Ra ≤0.8 µm - zofunika zomwe zimakakamiza kusinthanitsa pakati pa kachulukidwe ka sintering ndi post-MIM Machining. Malo athu amatchinga kusiyana kwake: timakhala pafupi-mawonekedwe a ukonde, kenaka timagwiritsira ntchito ma CNC amitundu yambiri kutsirizitsa ndi chithandizo cha kutentha chophatikizira-palibe zipangizo zakunja, palibe zolakwika zokonzanso, palibe kutaya kwa datum kupitiriza.
Kumene Muyezo wa MIM Imalephera—ndi Momwe Katswiri Wachindunji Amakonza
Ena anganene kuti wopereka MIM aliyense amatha kukonza zitsulo zosapanga dzimbiri ngati atsatira ASTM F2885. Koma njira zenizeni zolephera zimanena nkhani yosiyana. Tatsata kusweka kobwerezabwereza mumipando ya valve ya 316L kubwerera ku carbon binder yotsalira yomwe ili pamalire a tirigu-chilema chosawoneka ndi maso koma chowopsa chifukwa cha kukakamizidwa kwa cyclic. Kukonzekera sikunali kofulumira kubweza; inali kusintha kuchoka ku parafini kupita ku polyacetal-based binders *ndipo* ndikuwonjezera kuwongolera kwamlengalenga pre-sinter soak sitepe. Kusintha kumeneku kunabwera chifukwa cha zaka 12 zakugwiritsa ntchito ma AMS 5387 cobalt alloy nozzles —zida zokhala ndi mphamvu yokulira yofananira ndi matenthedwe koma zilango zokwera mtengo pazotsalira.
Chochitika chimenecho chimasamutsira mwachindunji ku chitsulo chosapanga dzimbiri. Metallurgists athu satenga 17-4 PH ngati "giredi ina." Amadziwa kuyankha kwake kokalamba kumasintha ngati kutentha kwa sintering kumayenda ± 5 ° C. Amatsimikizira ufa uliwonse womwe ukubwera ndi kusanthula kwa OES-osati kwa Fe/Cr/Ni kokha, koma pofufuza mpweya ndi nayitrogeni zomwe zimayang'anira kapangidwe ka pore. Ndipo iwo amalemba chilichonse chizindikiro: mame m'chipinda sintering, lamba liwiro mu uvuni debinding, ngakhale chinyezi yozungulira pa wobiriwira mbali akugwira. Chifukwa pamisonkhano yapampu yothamanga kwambiri, kusiyana kwa 0.3% kachulukidwe sikuli kongoyerekeza-ndikulephera kutopa msanga pa 12,000 psi.
Kuchokera Kujambula mpaka Kutumiza: Kodi "Kulondola Kwambiri" Kumatanthauza Chiyani Pochita
"Kulondola kwambiri" kumagwiritsidwa ntchito molakwika nthawi zonse. Kulondola kwenikweni kumatanthauza kubwerezabwereza magawo 500+, osati kusanthula kumodzi kwa CMM. Zimatanthawuza kukhala ndi malo enieni pamabowo a Ø3.2 mm omwe ali 42 mm motalikirana mkati mwa 0.015 mm—*pambuyo pa* sintering shrinkage, *pambuyo** mpumulo wa nkhawa, *pambuyo* passivation. Umu ndi momwe timaperekera:
- Kuwongolera komwe kukubwera: Ufa wosapanga dzimbiri wosapanga dzimbiri woyesedwa kuti ugawane kukula kwa tinthu (D50 ≤ 8.5 µm), kachulukidwe kowoneka bwino, komanso kuchuluka kwamayendedwe pa ASTM B212
- Kutsimikizira mkati: wobiriwira gawo kulemera adakhala pa patsekeke; kachulukidwe ka sintered kuyezedwa kudzera mu njira ya Archimedes poyambira ndi gawo lililonse la 50
- Kutsimikizira komaliza: Kuyendera kwa 100% CMM pamadatum ovuta; kusankha SEM/EDS pa fracture pamwamba kuti pore kusanthula pore
- Kutsata: Magawo aliwonse amakhala ndi satifiketi ya QR yolumikizira ufa, ID yoyendetsa sintering, chipika cha oyendetsa, ndi lipoti lomaliza loyendera.
Izi sizikuchulukirachulukira-ndizoyambira kwa makasitomala amafuta & gasi omwe amafunikira kutsata kwa ASME B31.4 kapena zolemba za EU PED 2014/68/EU. Sitikuwonjezera "ziphaso pambuyo pake." Timamanga kachitidwe kaye, kenako ndikuwunika motsutsa.
Kusankha Fakitale Yanu Yojambulira Zitsulo Zomangira Zitsulo Zosapanga dzimbiri—Yang'anani M'kabukuka
Ngati polojekiti yanu yotsatira ikukhudza zitsulo zosapanga dzimbiri za MIM za ma hydraulic manifolds, maziko a mpope, kapena ma hybrids osapanga dzimbiri a cobalt, funsani mafunso atatu musanasaine PO:
- Kodi angakuwonetseni mbiri yomaliza ya ng'anjo yotentha - ndikutsimikizira kuti ili ndi kutentha kwathunthu komwe kumagwiritsidwa ntchito pagiredi yanu?
- Kodi amapanga magawo a metallographic pazambiri zopanga, osati ma R&D okha?
- Pamene chojambula chikufuula "Ra ≤0.4 µm pamtunda wosindikizira," kodi amakina * pambuyo pa * sintering-kapena amadalira kupukuta kwachiwiri komwe kumachotsa chinsalu cholimba?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amayankha kuti inde onse atatu. Osati monga zonena zamalonda - koma monga zolembedwa, zowonekera mu njira zathu zowunikira za ISO 9001 ndikugawana momasuka pakuwunika kwa uinjiniya. Sitigulitsa mphamvu. Timagulitsa kulosera.
Pazofunikira zomwe zitsulo zosapanga dzimbiri MIM ziyenera kupereka zolondola komanso zodalirika, kuyanjana ndi a zitsulo jekeseni akamaumba zosapanga dzimbiri fakitale amene ali ndi unyolo wamtengo wapatali-kuchokera ku sayansi ya ufa kupita ku kuyezetsa kogwira ntchito-si phindu. Ndi njira yokhayo yomwe imapewa kukonzanso kokwera mtengo, kuchedwa kuyambika, ndi kulephera kwamunda. Tsogolo ndi la opanga omwe amawona zitsulo ngati uinjiniya-osati kugulitsa kunja.
