Pamene mainjiniya amatchula a fakitale yachitsulo yachitsulo, sikuti amangoyitanitsa nyumba-akuteteza kukhulupirika kwapangidwe pansi pa 300+ bar hydraulic pressure, kukhazikika kwa dimensional pambuyo pa njinga yamoto yotentha, ndi kutha kwa pamwamba komwe kumatsutsa kuvala kwa abrasive slurry. Ndicho chifukwa chake kulondola kumafunika kwambiri kuposa mtengo. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tapanga nyumba zopitilira 12,000 zamapampu a piston kuti zibowole m'mphepete mwa nyanja-iliyonse ikugwira ± 0.015 mm kulolerana pakubowola, kutsimikiziridwa ndi Zeiss CMM musanayambe chithandizo cha kutentha.
Chifukwa chiyani zitsulo zotayidwa zimalephera - komanso momwe kuponyera molondola kumalepheretsa
Zolephera zambiri zimatengera zomwe zimayambitsa: micro-shrinkage porosity pafupi ndi zigawo zokhuthala, kugawanika kwa tinthu tating'onoting'ono ta graphite m'magiredi achitsulo a ductile, kapena kupsinjika kotsalira kopangidwa ndi makina mumapangidwe amipanda yopyapyala. Timawona izi sabata iliyonse pakuwunika kwazinthu zomwe zikubwera-makamaka ndi ma billets a GGG-40 osatsimikizika ochokera kwa omwe si a ISO. Yankho lathu limayambira kumtunda: timangotengera chitsulo chovomerezeka cha EN-GJS-400-18-LT kuchokera kwa ogulitsa omwe adawerengedwa, ndikutsatiridwa kwathunthu mpaka malipoti a chemistry ya ladle. Kusungunuka kulikonse kumayang'aniridwa ndi spectrographic; Kuponyedwa kulikonse kumazizira pazitsulo zoyendetsedwa bwino - osati pansi pa nyumba yosungiramo katundu - kuti muchepetse nkhawa zamkati.
Ndiye pakubwera wosakanizidwa ndondomeko mwayi. Mosiyana ndi masitolo oyera oponyera, timaphatikiza kuponya mchenga ndi ma CNC amitundu isanu mu malo amodzi. Chophimba cha hydraulic valve chimafika ngati kuponyera kovutirapo. Mkati mwa maola 72, imachepetsedwa kupsinjika, yopangidwa kuti ifike pomaliza kuyitanitsa kwa GD&T (kuphatikiza kulekerera kowona kwa ± 0.02 mm pamabowo 16 okwera), ndikuwomberedwa chifukwa cha kupsinjika kwapamtunda. Palibe ma handoffs. Palibe kusuntha kwakukulu pakati pa ntchito. Kuphatikiza koyima kumeneku kumachepetsa nthawi yotsogolera ndi 38% motsutsana ndi unyolo wamba, ndikuchotsa "ndani yemwe ali ndi udindo?" kusiyana pamene nyumba ikuwotcha pa 250 ° C.
Kumene ma aloyi a cobalt amakumana ndi chitsulo chosungunuka-ndi chifukwa chake amagwira ntchito
Ntchito zina zimafuna zida zonse pagulu limodzi. Ganizirani za maziko a mpope wamatope: mazikowo ayenera kuyamwa kugwedezeka (kuchuluka kwa chitsulo cha ductile), pomwe mpando wosindikizira wapamwamba umafuna kukana kwa cobalt alloy. Tidaponya kachipangizo kachitsulo poyamba, kenako matumba a CNC-makina olondola osokoneza a AMS 5387 cobalt alloy insert. Mawonekedwe a geometry siwongotsatira-amatsatira malangizo a ASTM F2213 pakuchepetsa kufalikira kwa kutentha. Tatsimikizira kamangidwe kameneka pamagawo 47 otumizidwa ku zitsime zachipululu za Kuwaiti. Zero-mpando delamination pambuyo 18 miyezi mosalekeza ntchito.
Izi sizongoyerekeza. Amabadwa kuchokera ku kuyezetsa: kuyendetsa njinga zamoto kuchokera -20 ° C mpaka 280 ° C, 10,000-cycle kutopa Kutsegula, ndi kuyang'ana akupanga kwa mzere uliwonse wa bond. Makasitomala amafunsa kuti: "Kodi mutha kuwotcherera cobalt kukhala chitsulo?" Timayankha kuti: "Sititero - timapanga cholumikizira kuti kuwotcherera sikufunika." Ndiko kusiyana pakati pa kupanga ndi kugwirizanitsa ntchito.
Momwe kutumiza kwapadziko lonse lapansi kumawonekera - osati mabulosha
Kampani yaku North America OEM inkafunika ma roller 217 opangira ma winch center shaft roller pamagalimoto aukadaulo opangidwa ndi arctic. Wowagulitsira m'mbuyomu adaphonya masiku anayi chifukwa cha kuwonongeka kwa mchenga pamagawo a flange. Tidavomereza PO ndi zikhalidwe ziwiri: tidayendetsa chitsimikiziro cha nkhani yoyamba pazojambula zawo * tisanagwiritse ntchito zida, ndipo timatumiza magawo 100% owunikiridwa ndi malipoti a CMM payekha-osati chiphaso chotsatira.
- Tsiku 1: Kuwunika kwa GD&T kudawonetsa kuti palibe njira yabwino yosinthira zomwe zimapangitsa kuti pakhale chiwopsezo chachikulu - tidakonza zosintha za 0.8 ° zomwe zidawonjezera ziro mtengo koma zidachotsa 92% ya kukana kwamayendedwe oyendetsa.
- Tsiku 12: Kuponyedwa koyamba kwa 5 kunadutsa kuwunika kwa radiographic; kusanthula kwa microstructure kunatsimikizira chiŵerengero cha yunifolomu pearlite / ferrite pa ISO 945-1
- Tsiku 28: Mayunitsi onse 217 amatumizidwa ndi manambala okhazikika a laser, zolemba zoyesa kuuma, ndikugwirizanitsa deta pabowo lililonse lovuta.
Palibe ndalama zofulumira. Palibe zolipiritsa zonyamulira ndege. Kuwongolera njira zongolembedwa-kuchokera pa nambala yazinthu zopangira mpaka kuzinthu zomaliza zachinyezi. Ndiwo magulu odalirika ogula zinthu omwe amatsata: nthawi-mu-zathunthu (OTIF) ≥99.3% kudutsa maoda a 2023-2024.
Kusankha fakitale yanu yopangira zitsulo zotayira-kupitilira ziphaso
ISO 9001 ndi magawo a tebulo. Chomwe chimalekanitsa okondedwa ndi momwe amachitira ndi kusamvetsetsana. Wogula waku Europe atatitumizira zojambula zokhala ndi maziko a mpope - wopanda zinthu zakuthupi, zololera, zomaliza - sitinatchule mwachimbulimbuli. Tidayesa kuwunika kopanga zinthu: tidati EN-GJL-250 chitsulo chotuwa m'malo mwa ductile kuti chichepetse kugwedezeka kwabwino, mphero yam'mbali m'malo motopetsa kwanthawi yothamanga, ndikufanizira kupotoza kwamafuta mu SolidWorks Flow Simulation. Iwo adavomereza mapangidwe okonzedwanso m'maola 48.
Ndilo mtengo wosaneneka: kukambirana kwaukadaulo komwe kumalepheretsa kuyambiranso. Osati "tipanga zomwe mwatumiza." Koma "umu ndi momwe tingapangire kuti zigwire ntchito - modalirika, mobwerezabwereza, motsatirika." Kaya mukufuna 1 prototype kapena 5,000 mayunitsi apachaka, kaya chosungira chanu chimakhala ndi turbine 500-hp kapena subsea isolation valve — fiziki ya iron cast sisintha. Ngakhalenso njira yathu.
Ngati mukuyesa a fakitale yachitsulo yachitsulo, funsani mafunso atatu: Kodi angakuwonetseni malipoti a CMM kuchokera pakupanga mwezi watha? Kodi amayang'anira zonse zoponyera ndi makina - kapena zina zakunja? Ndipo pamene mapangidwe anu ali ndi mkangano pakati pa mphamvu ndi kulemera, kodi amapereka njira zothetsera-kapena kungoti "sizingatheke"? Mayankho amakuuzani zonse.
