Pamene mainjiniya ndi oyang'anira zogula amafufuza a Fakitale ya Metal Injection Molding, iwo samangoyang'ana mphamvu-iwo akufuna kudalirika kwa dimensional, kugwirizana kwa zinthu, ndi ntchito zotsimikiziridwa muzofunsira zopanikizika kwambiri. Koma izi ndi zomwe ambiri amapeza mochedwa: masitolo ambiri "MIM-okhoza" amangogwira ma geometries osavuta mu 316L kapena 17-4PH. Ndi ochepa okha omwe amakonza ma superalloys a cobalt-nickel, amasunga kutsata kwathunthu pamagulu omwe amathiridwa ndi kutentha, kapena kuphatikiza kuponyedwa ndi kumalizidwa kolondola kwa CNC-zonsezi zili pansi pa denga limodzi.
Chifukwa Chake Kusankha Zinthu Kumalamulira Mnzanu wa MIM—Osati Kungopanga Zinthu
Tawona makasitomala akubwerera katatu pachojambula chomwecho: choyamba cha porosity mu AMS 5387 pampu housings, chachiwiri kwa microcracking pambuyo kutentha kutentha, chachitatu kwa GD & T nonconformance pa mavavu mpando interfaces. Kulephera kulikonse kunayambika chifukwa chimodzi—osati kugwiritsa ntchito bwino zida, koma kusakwanira kwa zitsulo kumtunda. Ubwino weniweni wa MIM umayamba musanabadwe jekeseni: kutsimikizira ufa waiwisi waiwisi, kutsekemera koyendetsedwa ndi okosijeni, vacuum sintering ndi mbiri yeniyeni ya ramp / soak, ndi post-sinter HIP pamene pakufunika.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito yogwirizana ndi ISO pomwe gulu lililonse la cobalt alloy-kuchokera ku nozzles zochokera ku T800 kupita ku zigawo za pampu za AMS 5387-amayesa kusanthula kwa ufa (O/N/H zomwe zili, kugawa kwa tinthu), kutsimikizira kachulukidwe kagawo kobiriwira, ndikutsimikizira kachulukidwe ka sintered kudzera mu njira ya Archimedes. Palibe zongoganizira. Palibe kuchotsedwa kwa batch. Izi si zisudzo zotsatizana - ndimomwe mumapewera kusiyana kwa 12% mu 0.05 mm kulolerana.
Kuphatikiza Koyima Komwe Kumapereka Kukhazikika-Osati Zongotsatsa Zokha
Otsatsa ena akutulutsa sintering. Ena amalima makina omaliza. Kugawikana kumeneko kumapha kubwerezabwereza. Tayeza zolakwika zochulukirachulukira zopitilira ± 0.08 mm kwa ogulitsa atatu omwe akugwira gawo limodzi: kuponyera → sintering → grinding → kutsimikizira kwa CMM.
Pa QINGDAO QIANGSENYUAN, kuponyera ndalama, MIM, CNC Machining, ndi kumaliza pamwamba kumachitika mkati mwa chilengedwe chimodzi cholamulidwa. Thupi la ma valve opanikizika limasuntha kuchoka pakukonzekera chakudya kupita kumalo omaliza popanda kuwoloka doko lotumizira. Izi zikutanthawuza kuwongolera mbiri yamafuta, kuwongolera nthawi yomweyo kwa CMM, ndi ziro zokopa zazing'ono zomwe zimapangitsa kuti pakhale malo osindikizira. Ma cell awo a CNC okhala ndi ma multi-axis amachokera ku mawonekedwe a sintered pafupi ndi ukonde-popanda chowonjezera chachiwiri-ndikugwiritsa ntchito chithandizo cha kutentha komweko kokha kumene kuli kofunika kwambiri kukana kutopa.
Kuphatikizikaku kumapereka zotsatira zenizeni: 92% chiwongola dzanja choyamba pa GD & T-zofunika kwambiri; kulimba kosasinthasintha kwa Rockwell C58-62 kudutsa T800 shaft rollers; ndi malo obwerezabwereza amatha mpaka Ra 0.4 µm pamayendedwe a cobalt alloy-otsimikiziridwa ndi optical profilometry, osati kufananitsa kowoneka.
Komwe Mafakitole Ambiri a MIM Amalephera—Ndi Momwe Mgwirizano Waumisiri Umakonza
"Mungathe kupanga izi?" ndi funso loyamba lolakwika. Loyenera ndilakuti: "Kodi gawo ili * limachita * chiyani pakugwiritsa ntchito dongosolo?" Winch center shaft roller si silinda yokhayo yozungulira-ndiyense yonyamula katundu panjinga pakati pa kutsitsa kugwedezeka ndi kuwonekera kwa madzi amchere. Ma geometry ake ayenera kulinganiza kupsinjika, kusungidwa kwamafuta, komanso kukana dzimbiri.
QINGDAO QIANGSENYUAN imayika kuwunika kwauinjiniya *kusanayambe* zida. Gulu lawo limawonetsa ngozi zopanga kupanga koyambirira: kusintha kwa makulidwe a khoma komwe kumayitanitsa tsamba lankhondo, kutsika komwe kumafunikira ma elekitirodi okwera mtengo a EDM, kapena ma radii othina kwambiri kuti ufa usatuluke panthawi ya jekeseni. Samangonena kuti "inde" - amapangira njira zina zochirikizidwa ndi zoyeserera zovomerezeka za FEA. Pampu imodzi yaku North America OEM idachepetsa nthawi yotsogolera ndi 40% atasintha kuchoka ku "design-for-machining" kupita ku geometry yogwirizana ndi MIM.
Amakhalanso ndi mgwirizano waumisiri ndi ogulitsa zinthu zovomerezeka - osati zolemba zokha, komanso zowunikira pamodzi zitsulo. Pamene kasitomala anatchula AMS 5387 yokhala ndi ≤12 ppm sulfure kuti isawonongeke ndi dzimbiri, QINGDAO QIANGSENYUAN inagwirizanitsa kuyezetsa koyenera kwa zinthu zopangira ndi labu ya ogulitsa - kenaka imatsimikizira gawo lomaliza la chemistry kudzera mu mawonekedwe a OES pagawo lililonse.
Kusankha Fakitale Yanu Yopangira Majekeseni—Yang'anani Zikalata Zakale, Yang'anani Zomwe Mungachite
ISO 9001 imakuuzani kuti shopu ili ndi *system* yabwino. Sizikukuuzani ngati ogwira ntchito awo akhoza kugwira ± 0.015 mm pa nyumba ya cobalt 120 mm yokhala ndi mabowo asanu ndi limodzi odutsa. Funsani m'malo mwake:
- Kodi mumayang'ana kachulukidwe kachulukidwe pazambiri zilizonse zomwe zasungidwa - osati nkhani yoyamba?
- Kodi mungapereke kutsatiridwa kwazinthu zonse kuchokera pa satifiketi ya ufa mpaka ID yomaliza, kuphatikiza zipika za sintering?
- Kodi ndi chiyani chomwe mwapanga kwautali kwambiri pa AMS 5387 kapena T800-ndipo CPK ndi chiyani pama diameter ofunikira panthawiyi?
- Kodi mumakina mwachindunji magawo osiyidwa - kapena mukufuna kukonzanso pamzere wina wa CNC?
QINGDAO QIANGSENYUAN TECHNOLOGY imakumana ndi chilichonse mwa izi—osati monga kuchotserapo, koma monga machitidwe wamba. Cholinga chawo chimakhalabe chochepa: zigawo zachitsulo zolondola kumene kulephera sikungatheke - mavavu a hydraulic, nyumba zapampu, zida za m'mphepete mwa nyanja. Iwo samathamangitsa voliyumu. Iwo amapanga kubwerezabwereza.
Kwa mainjiniya omwe amafotokozera magawo omwe ali pansi pa> 300 bar pressure, kutentha kopitilira 450 ° C, kapena kuwululidwa ndi abrasive slurry - anu Fakitale ya Metal Injection Molding ayenera kuchita zambiri kuposa kubaya ufa wachitsulo. Iyenera kutsimikizira kapangidwe kake, kukhazikika, ndi magwiridwe antchito adongosolo. Izi sizipezeka m'mabuku. Zimatsimikiziridwa mumphuno iliyonse ya sintered cobalt, nyumba iliyonse ya pistoni yopangidwa ndi makina, shaft iliyonse yoperekedwa - pa nthawi, kulongosola, ndi kufufuza kwathunthu.
