Mainjiniya akamatchula gawo lomwe liyenera kukhala ndi ± 0.01 mm kulolerana pansi pa 350-bar hydraulic pressure-ndi kupulumuka mizunguliro 10,000+ mu abrasive slurry-samangofunika maziko. Amafunikira IMPRO Investment casting fakitale zomwe zimagwira zitsulo monga ma code ndi kukhazikika kwa dimensional monga lamulo la mgwirizano.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito imodzi yotere ku Qingdao-osati ngati malo ogulitsira zitsulo, koma ngati wothandizana nawo mwatsatanetsatane pazigawo zofunika kwambiri za mishoni pomwe kulephera sikuwononga ndalama zambiri, ndikowopsa. Tawonapo makasitomala akubwerera katatu ndi chojambula chofanana cha AMS 5387 cobalt alloy pampu: choyamba cha porosity pampando wa valve, chachiwiri kwa microcracking pambuyo pa kutentha kwa kutentha, chachitatu chifukwa kutsirizika kwa pamwamba sikunagwirizane ndi zomwe zimayendera. Nthawi iliyonse, chifukwa chake sichinali "khalidwe loponyera" -kunali kusagwirizana pakati pa machitidwe a alloy, mapangidwe a zitseko, ndi kutsatizana kwachisokonezo pambuyo pa kuponyera. Ndiko kumene fakitale iyi imapereka.
Chifukwa chiyani ma aloyi a cobalt-nickel amafunikira zambiri osati "kuponya ndalama"
Otsatsa ambiri amatenga AMS 5387 kapena T800 ngati giredi ina papepala. Zowonadi, ma alloys awa amachepera 17% kuposa 316 zosapanga dzimbiri panthawi yolimba, amapanga matenthedwe otentha 3 × otsetsereka m'zigawo zokhala ndi mipanda yopyapyala, ndikukana kupanga makina mwamphamvu kotero kuti zida za carbide zimavala 40% mwachangu ngati chithandizo cha kutentha chisanachitike sichinachitike nthawi yake. Tayesa izi panyumba zenizeni za silinda ya pampu ya piston zomangidwira mafuta akunyanja & ntchito yamafuta.
QINGDAO QIANGSENYUAN sichipereka ziyeneretso za aloyi. Gulu lawo laukadaulo limagwirizanitsa magulu azinthu zopangira ndi ogulitsa ovomerezeka - kutsatira kukula kwa tirigu, kufalikira kwa gawo la intermetallic, ndi zomwe zili ndi okosijeni mpaka 15 ppm. Makasitomala akatumiza bomba la T800 lomwe linali ndi kukokoloka kwapakhosi msanga, tidatsata kugwa kwa niobium carbide komwe kumatentha kwambiri. Kukonza? Kukonza njira yolowera panjira ndi 0.8°C/sekondi—ndikukhala ndi zolemba pa kilogalamu iliyonse.
Kuwongolera uku kumangogwira ntchito chifukwa cha iwo IMPRO Investment casting fakitale imaphatikiza masitepe ena nkhokwe: sera ya geometry ya geometry imatsimikiziridwa motsutsana ndi njira za CNC *pamaso* pomanga zipolopolo; njira zochizira kutentha zimalumikizidwa ndi zida zomaliza zamachining; zomaliza zapamtunda (Ra ≤ 0.4 μm) zimatsimikiziridwa pogwiritsa ntchito mawonekedwe a optical profilometry-osati ma tactile probes-chifukwa kutuluka kwa chipwirikiti kumafuna kubwereza kwa micron.
Kuphatikizika koyima sikuli buzzword - ndi inshuwaransi yololera
Mavenda ena amatchula makina oponyera okha, kenaka amagulitsa mashopu atatu osiyanasiyana. Izi zimabweretsa cholakwika chowonjezereka: kuponya shrinkage + makina osinthira makina + kupotoza kwamafuta = magawo omwe amakwanira pa CMM koma amamangirira pamodzi. Ku QINGDAO QIANGSENYUAN, gulu la ainjiniya lomwelo lili ndi unyolo wathunthu-kuchokera ku kutanthauzira kwa GD&T pakuyitanira kuwunika kojambula mpaka kuyesa komaliza kogwira ntchito pa benchi ya hydrostatic.
Tidatsata ma valavu 42 othamanga pamagawo awiri opanga. Zomwe zidapangidwa mkati mwanyumba zidawonetsa kubwereza kwa 92% pamalo osindikizira ovuta. Omwe adamaliza ntchito zakunja adatsika mpaka 68%. Kusiyana kwake? Zolakwika zosinthira kutengera kusintha kwa data zapakati pa 0.018 mm-zokwanira kusokoneza kutsekeka kolimba kwa thovu pa bar 250.
- CNC Machining: 5-olamulira munthawi yomweyo contouring kwa ndime zovuta zamkati mu maziko mpope
- Kuchiza kutentha: Kutsekera kwa vacuum ndi mapu a nthawi yeniyeni ya thermocouple mkati mwa katundu uliwonse
- Kumaliza: Electropolishing for corrosion resistance *ndi* micro-smoothness-kutsimikiziridwa ndi kujambula kwa SEM
Palibe sitepe yomwe imaperekedwa popanda kutsata zolembedwa: manambala ambiri, ma ID oyendetsa makina, zolemba zamakina, ndi malipoti a CMM osungidwa pamiyezo ya AS9102-ngakhale maoda osakhala apamlengalenga. Chifukwa pamene wodzigudubuza wa winch center shaft akulephera kukweza pakati pa chofukula migodi, "tinatsatira ndondomeko" sikokwanira. Mufunika umboni wa *chomwe* ndondomeko ndi momwe idagwirira ntchito.
Kutumiza kwapadziko lonse kumatanthauza kulabadira kwa uinjiniya—osati masiku a kalendala okha
"Kutumiza pa nthawi" sikukutanthauza kanthu ngati katundu woyamba afika ndi ulusi wolakwika pa pulagi ya cobalt alloy. QINGDAO QIANGSENYUAN imapanga ndandanda yolimba mu uinjiniya-osati mayendedwe. Oyang'anira ntchito zawo samangotsatira nthawi yotsogolera; amawonetsa zoopsa zomwe zingapangidwe *asanagwiritse ntchito zida.
Chaka chatha, kasitomala waku Europe adapereka GD&T yokonzedwanso ya hydraulic manifold block. Gulu lathu lidawona kuti kulolerana kwamalo (± 0.025 mm) padatum C kungafune kugaya pambuyo poponya-kuwonjezera $ 1,200 / unit ndikuchedwa kwa masabata atatu. M'malo mwake, adaganiza zosintha chosindikiziracho kuti chisamutsire datum pamalo opangidwa ndi makina, kukwaniritsa magwiridwe antchito omwewo pamtengo wotsika wa 40%. Wothandizira adavomereza mu maola 48.
Izi zimachitika chifukwa mainjiniya awo amalankhula zonse zoyambira komanso zamadzimadzi. Amadziwa chifukwa chake kutsitsa kwa 0.1 mm pakona yakutulutsa kwa nozzle kumasintha magwiridwe antchito ndi 11%. Ayesa ma coefficients pa 17 cobalt alloy geometries - osati kungoyerekeza kokha, koma ndi mabenchi oyenda omwe amayendetsa madzi enieni ogwira ntchito.
Ngati mukuyang'ana zida zachitsulo zolondola kwambiri pomwe magwiridwe antchito amadalira kukhulupirika kwa microstructure, osati miyeso yayikulu, kusankha sikuli pakati pa ogulitsa - kuli pakati pa zongoganiza ndi umboni. An IMPRO Investment casting fakitale sichimalonjeza ungwiro. Imapereka zotsatira zotsatirika, zobwerezabwereza, zovomerezeka mwantchito-chinthu chimodzi chofunikira panthawi imodzi.
