Kuphwanyidwa sikosangalatsa mu ma valve othamanga kwambiri a hydraulic kapena m'mapampu olondola - sizingakambirane. Kupatuka kwa mamilimita 0.02 okha kudutsa 300-mm mbale-leveling pamwamba kungayambitse kulephera kwa chisindikizo msanga, kugawa katundu mosiyanasiyana, kapena kusokonekera koopsa mumisonkhano yapampu ya cobalt-alloy piston. Taziwonapo kawiri m'miyezi yapitayi ya 18: imodzi ya North America OEM inachedwetsa kutumiza ndi masabata asanu ndi limodzi itatha kukana nyumba za silinda 47-kungopeza chomwe chimayambitsa sikunali kulakwitsa kwa makina, koma kusagwirizana kwa mbale-kukweza pamwamba pamtsinje pokonzekera zopangira.
Chifukwa chiyani "Plate Levelers Metal Parts Factory" Ndi Nthawi Yosaka Yosokeretsa —ndi Zomwe Injiniya Amafunikiradi
Magulu ambiri ogula zinthu amalemba "mafakitale azitsulo za mbale zolezera zitsulo" mu Google akuyembekeza kuwongolera kukhazikika kwa turnkey. Koma kuwongolera kutsika kwenikweni kwa dziko lapansi kumayamba kalekale kusanakhazikike - kumayamba ndi kusankha kwa zinthu, kapangidwe ka tirigu, ndi mbiri ya kutentha. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sitiwona kukweza mbale osati ngati gawo lomaliza, koma monga chimake cha njira yolumikizidwa mwamphamvu: maziko achitsulo opangidwa ndi mchenga amakumana ndi kupsinjika * pamaso pa * CNC mphero; Zolemba za AMS 5387 cobalt alloy zimachitika pa 950 ° C kwa maola 4 pambuyo poponyera kuti zikhazikitse microstructure-kenako zimaziziritsidwa ndi mpweya woyendetsedwa bwino kuti muchepetse tsamba lankhondo. Pokhapokha pamene timayika milingo yolondola kudzera pamapuleti apawiri-axis hydraulic ± 0.5 µm kubwereza.
Uku sikukongoletsa kokongola. Ndi kukhazikika kwa ntchito. Matupi athu a valve opanikizika amafunikira ≤0.015 mm chiwerengero chonse chowerengera (TIR) kudutsa ma flanges okwerera. Zodzigudubuza za Winch center shaft zimafuna ≤0.025 mm zothamanga kupitirira mamita 1.2—kuyezedwa pa Zeiss Contura G2 RFS ndi kufufuza kolipiridwa ndi kutentha. Timatsimikizira gawo lililonse ndi makina oyezera (CMM), osati pongoyang'ana komaliza - komanso pambuyo pokonza movutikira, pambuyo pochiritsa kutentha, komanso pambuyo popera pamwamba. Kutsimikizira kwa mfundo zitatu kumeneko kumagwira kupotoza kotentha koyambirira - kusanachitike kukonzanso kokwera mtengo.
Zinayi Zosakambirana za True Plate-Leveling Control
- Kufufuza kwazinthu kumapangidwira pakuwongolera magwiridwe antchito: Billet iliyonse ya T800 ya cobalt alloy imakhala ndi lipoti la mayeso a mphero (MTR) yokhala ndi chemistry yathunthu komanso data yokhazikika. Timadumpha manambala a batch a MTR motsutsana ndi zipika zosanjikiza - kotero ngati kutsetsereka kwamtunda kumawoneka mu Loti #QSY-2388, timadzipatula ngati ndikutsitsa, kuzizira kwa ng'anjo, kapena kuvala kwa mbale.
- Njira-integrated metrology: Palibe "mulingo ndiye kuyeza." Timalinganiza pamene tikusanthula-kugwiritsa ntchito laser interferometry yolumikizidwa ndi kayendedwe ka hydraulic platen. Izi zimazindikira kuyambika kwanthawi yeniyeni, makamaka pamaziko a pampu opyapyala pomwe kupsinjika kotsalira kumabwerera pakangotha mphindi zochepa kutsitsa.
- Kusunga umphumphu pamwamba: Kusanja kwachikhalidwe kumapondereza zigawo zapansi panthaka, kupangitsa ming'alu yaying'ono muzitsulo zowuma za cobalt. Njira yathu imagwiritsa ntchito kutsika kwamphamvu, kutsika kwapang'onopang'ono-25 Hz pa 0.3 mm matalikidwe-kupumula kupsinjika kwamkati popanda kupunduka kwa pulasitiki. Kutsimikiziridwa ndi kusanthula kwa phokoso la Barkhausen pa batch iliyonse ya nozzle ya AMS 5387.
- GD&T-aware leveling strategy: Sitifewetsa mpaka "zero" - timakhala ndi ma datamu ogwira ntchito. Nyumba yosungiramo silinda siinapangidwe ku nkhope yake yayikulu; imakwezedwa kumtunda wonyamula, wotchulidwa kuchokera kuukadaulo wapamwamba. Izi zikutanthauza kuti mphamvu yowongolera imagwiritsidwa ntchito mosiyanasiyana-yowerengeka pagawo lililonse la geometry pogwiritsa ntchito finite element simulation pre-run.
Zomwe Zimalephera—Ndipo Chifukwa Chake Mafakitale Ambiri Akuphonya
Mashopu ena amachokera ku malo opangira zitsulo zogwiritsidwa ntchito wamba. Amapeza magawo "ophwanyika" - koma amalephera kuyesa ntchito. Chifukwa chiyani? Chifukwa malowa amakwaniritsa kukhwinyata pamwamba, osati kusalala bwino. Makasitomala m'modzi waku Europe adatitumizira maziko a pampu okanidwa: pamwamba TIR inali 0.012 mm, komabe idatsikira pa bar 280. Tidayeza kuthyathyathya *kuyerekeza ndi bwalo la bawuti* lokwera, osati m'mphepete mwakunja, ndipo tidapeza kupatuka kwa 0.041 mm kudutsa patani ya 8-bolt. Vuto silinali makina owongolera. Kunali tanthauzo la datum.
Ena amadalira kokha CNC nkhope mphero. Koma mphero imachotsa zinthu—sizimathetsa nkhawa. Tidayeza tsamba lankhondo la 0.06 mm muzitsulo zokhuthala za 40-mm *pambuyo* mphero, chifukwa chochotsa katundu. Yankho lathu? Yesani kuponya mopanda kanthu, mphero yokhala ndi njira zoyendera bwino, kenako mulingo wapakatikati ndi zilowerere zotentha. Njira zitatu - osati imodzi.
Kuchokera ku Flatness kupita ku Functional Reliability
Kupambana kwenikweni kwa ma plate-leveling kumawonekera kumunsi kwa mtsinje: moyo wautali wosindikizira m'ma hydraulic manifolds, kuchulukira kosasunthika pamapampu amitundu yambiri, kugwedezeka kwa zero mu ma winch drive shaft akuzungulira 1,200 rpm. Ku QINGDAO QIANGSENYUAN TECHNOLOGY, sitimagulitsa "mbale zafulati." Timapereka kukhazikika kwapang'onopang'ono pamatenthedwe, ma spikes, komanso kutopa kwamakina - kutsimikiziridwa ndi ASTM E1157, ISO 1101, ndi mayeso okhudzana ndi kasitomala.
Ngati ntchito yanu ikufuna kusanja pansi pa katundu - osati pa tebulo la granite - yambani ndi khalidwe lakuthupi, osati makina. Fufuzani kufufuza mpaka ku batch yosungunuka. Imafunika kusanja kwa GD&T-osati kufuntha kwachibadwidwe. Ndipo kuumirira pa muyeso pamalo aliwonse osinthira matenthedwe ndi makina. Umo ndi momwe kulondola kumakhala kotheka. Umu ndi momwe "fakitale yazitsulo zopangira mbale" imasiya kukhala mawu osakira - ndikukhala chofunikira chaukadaulo.
