Mainjiniya akamatchula fakitale yazitsulo zopangira ma jakisoni azigawo zolondola kwambiri, sikuti amangopeza zinthu zokha - amathandizira kuti pakhale kukhazikika pansi pa 120 MPa hydraulic katundu, kusasinthika kwapang'onopang'ono pamagulu 500, ndi kulekerera zero pamwamba pa nozzles za cobalt-alloy. Ndicho chenicheni cha ntchito-osati chinenero cha malonda. Tawona ntchito zambiri zikuyimitsidwa pakuwunika kwa GD&T chifukwa wogulitsa adatenga AMS 5387 ngati "aloyi ina." Kupambana kwenikweni kwapadziko lonse lapansi kumayamba ndikudziwitsa anthu zamakhalidwe, osati manambala amndandanda.
Chifukwa Chake Kumangirira Kwachitsulo Kokha Sikokwanira Kumagawo Ofunika Kwambiri
Metal injection molding (MIM) imapambana pakuvuta kwa mawonekedwe a ukonde: makoma owonda, mafupi, ulusi wabwino. Koma nyumba zapampopi zamafakitale, ma valavu oponderezedwa, ndi ma roller a winch center shaft amafuna zambiri kuposa geometry. Amafunikira kamangidwe kake kambewu kolamuliridwa pambuyo powotchera, kusokonekera kodziwikiratu pakuchiritsa kutentha, ndi kuuma kwapamtunda komwe kumapulumuka kutuluka kwa slurry - popanda makina a post-sinter kusokoneza kachulukidwe kachulukidwe. Ndipamene kuphatikiza koyima kumakhala kosakambitsirana.
Takumana ndi mitundu itatu yolephera mobwerezabwereza kwa ogulitsa a MIM okha:
- Kuyenda kwapang'onopang'ono kupitirira ± 0.05 mm pazibowo za silinda pambuyo pochepetsa kupsinjika
- Magulu a Micro-porosity muzitsulo zonyamula katundu, zomwe zimayambitsa kutopa msanga
- Kuyankha kosagwirizana kwa cobalt-nickel alloy ku HIP (kukankhira kotentha kwa isostatic), kumayambitsa kusiyanasiyana kwa batch-to-batch mu mphamvu zokolola.
Kukonza sikuli bwino MIM yokha. Ikuphatikiza MIM ndi kumalizidwa kolondola kwa CNC, kuwongolera kutentha kwamlengalenga, komanso kutsimikizira kwa CMM pamayendedwe aliwonse amatenthedwe. Umu ndi momwe mumatsekera kulondola kwenikweni kwa magwiridwe antchito-osati kulondola kwa zodzikongoletsera.
Zida Zinayi Zaukadaulo Zomwe Zimasuntha Singano
Osati onse opanga zitsulo zazitsulo amawongolera zosinthika zomwezo. Izi ndi zomwe zimalekanitsa magwiridwe antchito obwerezabwereza ku zotsatira zabwino:
- Kutsatiridwa Kwazinthu Kufikira Ku Nambala Yotentha: Gawo lililonse la T800 lokhala ndi cobalt limakhala ndi kusanthula kolembedwa kwa kusungunuka, kuphatikiza nayitrogeni yotsalira ndi mpweya wa okosijeni - wofunikira pakukana dzimbiri m'malo a mpweya wowawasa. Palibe njira zazifupi zomwe "zotsimikizika kutchuthi".
- Kutsimikizika kwa Njira Yophatikiza: Pazigawo zapampu za AMS 5387, timatsimikizira kutsatizana kwathunthu: gawo lobiriwira la MIM → debinding → sintering → HIP → CNC yoyipa → kutentha kutentha → kumaliza CNC → kupitilira kwapansi. Gawo lirilonse liri ndi magawo omwe atchulidwa - ndipo kupatuka kumayambitsa kugwira basi.
- Kuyang'anira Ntchito, Osati Macheke a Dimensional: Nyumba ya silinda ya pisitoni imayesedwa ndi hydrostatic pa 1.5 × ntchito yokakamiza isanatumizidwe. Pulagi ya cobalt alloy imapeza kusanthula kwa ultrasonic kwa subsurface discontinuities-osati lipoti logwirizana.
- GD&T-Aware Machining Setup: Mapulogalamu athu a CNC amitundu yambiri amalemekeza kutsogola kwa datum. Ngati kujambula kwanu kukuwonetsa kulolerana ndi ndege yachiwiri, zosintha zathu zimakakamiza ndegeyo poyamba - palibe zongoganiza, palibe kukonzanso.
Zomwe Akatswiri Amanyalanyaza Akamanena "Kulondola Kwambiri"
Ena angatsutse kuti kulolerana kolimba kumangotanthauza mbali zabwinoko. Komabe, kulolerana mopambanitsa popanda kuganizira momwe zimagwirira ntchito kumayendetsa mtengo-ndi chiwopsezo. A ± 0.01 mm m'mimba mwake pa bwana wosafunikira kwambiri samawonjezera phindu. Koma kugwira ± 0.005 mm pampando wa valve wosindikiza pamwamba? Izi zimalepheretsa kukokoloka kwa cavitation pa 3,000 RPM.
Nthawi zambiri timayimitsa izi pakuwunika kwaukadaulo:
- Kusintha maziko a mchenga ndi MIM kumakhala komveka ngati kuchepetsa kunenepa kumathetsa 22% mtengo wapamwamba wa unit - ndipo pokhapokha ngati pulogalamuyo ipewa kuyendetsa njinga yotentha pamwamba pa 400 ° C.
- T800 alloy imapereka kukana kovala bwino, koma machinability ake amatsika 60% motsutsana ndi muyezo 316 wosapanga dzimbiri. Tidzaperekanso njira zina zowumitsira kapena zochiritsira zapamtunda ngati kutulutsa kuli kofunikira kuposa kuuma kochuluka.
- Zofunikira zomaliza pamwambazi ziyenera kugwirizana ndi mphamvu zamadzimadzi: Ra 0.4 µm pamayendedwe amkati amachepetsa chipwirikiti; Ra 3.2 µm pamalo okwera akunja amapulumutsa 37% panthawi yomaliza
Kuwonekera pano si ntchito-ndi kuchepetsa chiopsezo. Chifukwa mtengo weniweni si mawu. Ndikuchedwa kwa masabata asanu ndi atatu pamene magawo 50 oyambirira amalephera kuyesa ntchito.
Kupanga Molondola Komwe Kumagwira Ntchito—Osati Kungopita Kumayendera
Fakitale yopangira jakisoni wazitsulo imapangitsa kuti anthu akhulupirire mwa kupatsidwa chilango - osati ziphaso zapakhoma. Kutsata kwa ISO kumafunikira pokhapokha ngati ikumasulira ku zolemba zoyendera zolembedwa pagawo lililonse, kutsatiridwa kwathunthu kwazinthu kubwerera ku mphero ya ingot, ndi kuchotserapo ziro ku protocol 100% yoyang'ana zowonera pamalo ofunikira osindikizira.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito motere chifukwa makina a hydraulic samakhululukira kusamvana kosagwirizana. Mavavu amafuta ndi gasi samalekerera micro-porosity pafupi ndi malire okakamiza. Mawilo agalimoto zamainjiniya samavomereza kutengeka pang'onopang'ono pambuyo pa njinga yamoto yotentha.
Ndicho chifukwa chake cholinga chawo chimakhalabe chochepa: ma valve okakamiza, zosungiramo masilinda, maziko a pampu, ndi mawilo a winchi - osati "zigawo zonse zachitsulo." Kuzama kumadutsa m'lifupi pamene miyoyo ndi zipangizo zimadalira kudalirika. Chisinthiko chawo chotsatira - R&D m'njira zosakanizidwa zosakanizidwa - sizidzathamangitsa zachilendo. Idzathetsa vuto lotsatira: kuchepetsa nthawi yotsogolera pazinthu za AMS 5387 popanda kupereka nsembe yobwerezabwereza ya HIP.
Ngati polojekiti yanu ikufuna magawo omwe akugwira ntchito mokakamizidwa, osati kungoyang'ana papepala, yambani ndi ndondomeko - osati mndandanda wa luso.
