Kupereka kwa fakitale ya QT450-10 sikungotengera zinthu - ndi lonjezo lantchito. Pamene matupi a hydraulic valve, ma pump housing, kapena ma winch center shafts ayenera kukana kutopa pansi pa kukweza kwa cyclic pamene akugwira zolimba za GD & T, QT450-10 ductile iron imapereka mlingo woyenera: 450 MPa mphamvu zolimba, 10% kutalika kwazing'ono, ndi makina odziŵika bwino pambuyo pa annealing. Koma kupeza ma QT450-10 sikungokhudza kupeza * chilichonse * choyambira. Ndizokhudza kuyanjana ndi wogulitsa yemwe amawongolera zitsulo kuchokera ku ladle kupita ku lathe-ndipo ndipamene kuphatikiza koyima kumakhala kosakambitsirana.
Chifukwa chiyani QT450-10 Imafunikira Zambiri Kuposa Kuyimba Wamba
Tawonapo mfundo zitatu zolephera zomwe zimachitika m'mapulojekiti a QT450-10: kusagwirizana kwa nodularity kumayambitsa kusweka msanga m'makona opanikizika kwambiri; kusokonezeka kwapang'onopang'ono kotsalira pamakina omaliza a CNC; ndi ma microcracks pamwamba amawululidwa pokhapokha atayesa kukakamiza. Izi sizikupanga "zolakwika". Ndizizindikiro za kugawika kwa ntchito - komwe kuponyera, kutenthetsa, ndi kukonza makina kumachitika kwa ogulitsa osiyana omwe ali ndi mazenera osagwirizana.
Makina a QT450-10 amatengera kuwongolera bwino kwamankhwala a magnesium, nthawi yothira, komanso kuzizira mu nkhungu. Kupatuka kwa 3 ° C mu kutentha kwakuthira kumatha kusintha kuchuluka kwa nodule ndi 20%. Ichi ndichifukwa chake kutsatiridwa kwazinthu zovomerezeka kumafunikira-osati ngati zolemba, koma ngati ulalo wamoyo wamalipoti owunikira ma ladle ndi zolemba zakale zamafuta. Pamalo athu a Qingdao, gulu lililonse la QT450-10 limanyamula zida zonse (C: 3.4-3.8%, Si: 2.2-2.8%, Mg: 0.03-0.06%), mipiringidzo yoyeserera yoponyedwa pambali pazigawo zopanga, komanso kulimba kwa mapu pa makulidwe agawo.
Izi sizongoyerekeza. Chaka chatha, pampu yaku Europe ya OEM idasinthiratu kwa ife pambuyo poti ogulitsa awiri adalephera kukhazikika pazinyumba zamasilinda okhala ndi zigawo za khoma la 120 mm. Malonda awo oyambirira ankagwiritsa ntchito nkhungu zamchenga zokhala ndi zomangira zadothi wamba—kuchititsa kuti kuzizirike kosiyana ndi kumanga ngale. Tinasinthira kumchenga womangidwa ndi utomoni wokhala ndi mpweya wowongolera ndikuwonjezera kutsitsimutsa kwa post-cast pa 580 ° C kwa maola anayi. Zotsatira: kupotoza kwatsika kuchokera ku ± 0.18 mm kufika ku ± 0.06 mm-mkati mwa malo awo olekerera a CMM.
Kodi "Factory Direct" Imatanthauza Chiyani Kwa Ogula QT450-10
Otsatsa ena amadzitcha "fakitale ya QT450-10" chifukwa ali ndi malo oyambira. Ena amapeza dzinali chifukwa ali ndi mtengo wonse - kuchokera kusungunuka kwa alloy ndi kuponyera kudzera mu mphero zisanu, kuwomba, ndi kuyesa kwa helium. Kusiyanaku kumawonekera pakusinthasintha kwa nthawi yotsogolera, kuthamanga kwa mapangidwe, komanso kusintha kwazomwe zimayambitsa.
- Kutumiza-ku-machining kumagwira ntchito m'nyumba imodzi: Palibe kuchedwa kwa mayendedwe, palibe kuwonongeka kwapambuyo, palibe kulumikizana molakwika pamawu a data.
- GD&T imatsimikiziridwa makina asanayambe: Gulu lathu la metrology limasanthula magawo omwe amaponyedwa pogwiritsa ntchito masikelo owunikira okhazikika-kuyerekeza malo enieni ndi CAD yomwe imatchedwa CAD kuti isinthe njira zosinthira masheya.
- Chithandizo cha kutentha chimaphatikizidwa, osati kunja: Timayendetsa mizere yosalekeza yokhala ndi ma rampu / zilowerere / zoziziritsa, zowunikira pa ASTM E2862, yokhala ndi ma chart a ng'anjo omwe amasungidwa pagawo lililonse.
Kuphatikizika kumeneko kumachepetsa kutembenuka kwa prototype kuchokera ku masabata a 12 kufika ku 5. Kwa malamulo apakati (500-5,000 pcs / chaka), amachotsa "foundry bottleneck" yomwe imapangitsa ogula kukhala ndi chitetezo cha miyezi 6. Makasitomala m'modzi waku North America adachepetsa mtengo wonyamulira ndi 37% atasamukira ku mtundu wathu wachindunji wa fakitale ya QT450-10.
Pamene QT450-10 Siikukwanira-ndi Zomwe Muyenera Kuchita M'malo mwake
Mainjiniya ena amasankhira QT450-10 pazogwiritsa ntchito zonse zachitsulo. Koma timalangiza mosiyana pamene: kutentha kwa ntchito kupitirira 300 ° C (kuwola kwa pearlite kumathamanga); kuvala kukana ndikofunikira (mwachitsanzo, ma ring ring grooves); kapena kuwonekera kwa dzimbiri kumaphatikizapo ma kloridi kapena H₂S. Zikatero, QT500-7 imapereka mphamvu zapamwamba koma kutsika kwa ductility-kapena cobalt alloy T800 imapereka 3 × moyo wovala pa 650 ° C.
Izi ndi zomwe timachita m'malo mwake: yendetsani zida zoyeserera panthawi yowunikira uinjiniya. Ngati gawolo likuwona> 200 MPa kusinthana kupsinjika, timatengera moyo wotopa pogwiritsa ntchito zovuta zakumaloko mu nCode DesignLife. Ngati kuuma kwa pamwamba kuyenera kupitirira 350 HB, timalimbikitsa magiredi a ductile iron (ADI) ngati ASTM A897 Grade 2. Ngati geometry ili ndi nthiti zopyapyala (<8 mm) sachedwa kufota, timasinthira ku ndalama zopangira ndalama - ngakhale chitsulo cha ductile - kuti titsimikizire kumveka bwino.
Izi sizikukhumudwitsa. Zimalepheretsa kulephera kwamunda. Takana mawu 17 a QT450-10 m'miyezi 18 yapitayi chifukwa pulogalamuyo ikufuna zina. Chikhulupiliro chimayambira pamenepo.
Kusankha Mnzanu wa QT450-10: Macheke Atatu Osakambirana
Musanasaine NDA, funsani mafunso awa-ndipo funsani umboni:
- Kodi mungandiwonetse malipoti omaliza atatu omaliza a QT450-10? Osati ziphaso zokha—zosindikiza zenizeni zokhala ndi sitampu yanthawi, ID ya opareshoni, ndi zipika za ma spectrometer.
- Kodi mumapanga kuyesa kwa akupanga pamapangidwe okhuthala kuposa 50 mm? ASTM A609 Level 3 ndiyokhazikika pazigawo zofunikira kwambiri. Ngati anena “pokhapokha,” chokanipo.
- Kodi Cpk yanu yoyipa kwambiri ndi iti yamphamvu yolimba pa QT450-10 m'miyezi 12 yapitayi? Chilichonse chomwe chili pansi pa 1.33 chimatanthauza kusakhazikika kwa chiwerengero. Yathu ndi 1.68.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito fakitale ya QT450-10 yomangidwa kuti ikhale ndi magawo ofunikira kwambiri - osati zopangira zinthu. Sitikusungiramo zinthu zonse zomwe sizinalembedwe. Timapanga magulu ogwirira ntchito: ma valve oponderezedwa okhala ndi mipando yophatikizika, maziko a pampu okhala ndi mabowo okhomeredwa kale, ma roller a winchi okhala ndi mipikisano yolimba - zonse kuchokera pakuponya kamodzi kwa QT450-10. Cholinga chimenecho chimatithandiza kukonza njira zomwe ena sakuziwona: kuwongolera ma graphite morphology pogwiritsa ntchito makina osowa padziko lapansi, kugwedera kothandizidwa ndi kugwedezeka kuti tichepetse hydrogen porosity, komanso kutsimikizira kwa nodularity pogwiritsa ntchito kusanthula kwazithunzi.
Chotsatira sichikupempha mtengo. Ikutumiza zojambula zanu kuti mupeze mayankho opangira - popanda zingwe zomata. Chifukwa njira yabwino kwambiri ya QT450-10 imayamba kutsanulira koyamba.
