Pamene mainjiniya afotokoza ductile iron Investment cast kwa mavavu opangidwa ndi ma hydraulic hydraulic kapena nyumba zapampu, sikuti amangosankha chinthu - akudzipereka kuti azitha kukhazikika pansi pa 350-bar pressure, microstructural consistency kudutsa 500-part batches, ndi zero kulolerana kwa graphite nodule clustering. Chifukwa chake kusankha koyenera ductile iron Investment casting fakitale sizokhudza ma chart a kuchuluka kapena ziphaso za ISO zokha. Ndi za ndani yemwe amatsimikizira kuyimba kwa GD&T chida chisanayambe-ndipo ndani amatha kupatuka pakhoma la 0.012 mm poyang'anira chipolopolo, osati pambuyo pochiritsa kutentha.
Chifukwa chiyani kuponya kwachitsulo kwa ductile kulephera - kusanayambike
Tawona zifukwa zitatu zomwe zimabwerezedwa m'maere okanidwa: kusagwirizana kwa nodular chifukwa cha kupangidwa kwa ndalama zosatsimikiziridwa; kupotoza kwa nkhungu kuchokera kumayendedwe othamangitsidwa mwachangu; ndi kujambula pamwamba pa kaboni panthawi yotentha kwambiri ya zipolopolo za ceramic. Palibe amene amawonekera pa lipoti loyesa. Zonse zimangowoneka pakulephera kwamunda-monga pampu ya pisitoni ikusweka pa maola ogwirira ntchito 18,000 m'malo mwa 45,000. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Timachita chitsulo chosapanga dzimbiri osati ngati kalasi yamtengo wapatali koma ngati zitsulo. Kusungunula kulikonse kumayamba ndi Fe-Si-Mg master alloys ovomerezeka - osati ma noduzers amtundu uliwonse - ndipo batch iliyonse imatsimikiziridwa ndi spectrographic * isanatsanulidwe. Timakhala ndi nodularity pamwamba pa 85% (pa ASTM A536 Giredi 65-45-12) m'magawo onse okhuthala kuposa 40 mm - osati pamipiringidzo yokha.
Kuphatikizika koyima komwe kumatsekereza magwiridwe antchito - osati magawo okha
Ambiri oyambitsa amagawira ochita masewera a chipani chachitatu. Izi zimapanga mipata yovuta: kupotoza kwa kutentha pakati pa kuponyera ndi kupanga makina, maumboni osagwirizana ndi ma data, komanso kutayika kowoneka bwino pamene zolemba zochizira kutentha sizikugwirizana ndi zida za CNC. QINGDAO QIANGSENYUAN ndiye eni ake tcheni chathunthu—kuchokera ku nkhungu zopangidwa ndi zipolopolo kudzera pa mphero za ma axis asanu ndi kuuma kwa nitride pamwamba. Kwa wodzigudubuza wa winch center shaft wofuna kuzungulira kwa ± 0.005 mm ndi kulimba kwa 58 HRC pamwamba, izi zikutanthauza kukonza pomwe kuponya kukadali mkati mwa 20 ° C wa kutentha kwake kochepetsa kupsinjika. Palibe kukonzanso. Palibe kuyezanso. Datum imodzi yokha, mbiri yakale yotentha, mzere umodzi woyankha. Tadula nthawi yotsogolera yamagulu ovuta achitsulo ndi 37% motsutsana ndi mitundu yogawa-osati mopupuluma, koma pochotsa kuchedwa ndi kukonzanso malupu.
Kumene "kulondola" kumakumana ndi zovala zenizeni
Ductile iron Investment casting imapereka phindu pokhapokha geometry ikugwirizana ndi ntchito-osati zolemba zamakalata. Ganizirani za AMS 5387 cobalt alloy pump impeller hub kuponyedwa mu chitsulo cha ductile potengera mayendedwe okwera mtengo. Mawonekedwe ake ndi shaft yachitsulo chosapanga dzimbiri ayenera kukhalabe ndi zosokoneza pambuyo pa ma 12,000 matenthedwe. Malipiro ocheperako akulephera apa. Gulu lathu limagwiritsa ntchito njira zomalizitsa zomalizitsa kuti zilosere kugundana komwe kumachitika m'malo okhala ndi makulidwe a 3:1—ndikusintha makulidwe a sera moyenerera. Tapereka nyumba zamasilinda zamapampu amadzi othamanga kwambiri pomwe kuwongoka kunakhala mkati mwa 0.008 mm kutalika kwa 320 mm, kutsimikiziridwa kudzera pa sikani ya CMM yotsatiridwa ndi laser-osati ma plug geji. Kulondola kumeneko si mwayi. Ndilo data yokulirapo ya zipolopolo, kuwongolera ma ramp owongolera, komanso kutsika kwa kutentha kwanthawi yeniyeni komwe kumalumikizidwa kutsanulira kulikonse.
Kusankha fakitale yanu ya ductile iron investment casting-kupitirira kabukuka
Funsani mafunso anayi awa musanasaine PO:
- Kodi mungagawane nawo ma certs azinthu zitatu zomaliza za Grade 65-45-12-ndikutsimikizira kutsata kwa chiwerengero cha kutentha? (Osati ma mill certs-malipoti enieni a ladle.)
- Tiwonetseni ndondomeko yanu yopangira mapu amtundu wa valve 120 kg. (Kodi mumagawa ndikuyika gawo lililonse-kapena kudalira kulumikizana kwa ultrasonic velocity?)
- Kodi mumatsimikizira bwanji kukhazikika kwa dimensional pambuyo pothetsa kupsinjika? (Timagwiritsa ntchito kusanthula kwa 3D kusanachitike komanso pambuyo pa chaka pagawo loyambirira, osati kungoyang'ana malo a CMM.)
- Kodi kulekerera kwanu kwakukulu kwa makulidwe a khoma kwa chitsulo choponyera ndalama choposa 35 mm ndi chiyani? (Yankho lathu: ±0.8 mm—lotsimikizika pa ASME B16.34 Annex F.)
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito kuchokera ku Qingdao ndi chithandizo chachindunji chaukadaulo kwa makasitomala aku North America, Europe, ndi Southeast Asia. Sitigulitsa ma castings. Timapereka umphumphu wogwira ntchito-kuyezedwa mu nthawi yogwira ntchito, osati kulemera kwake. Pamene gawo lanu lotsatira lolemetsa likufuna kulimba kwachitsulo chachitsulo ndi kukhulupirika kwa ndalama, yambani ndi omwe amayesa chiyani-ndi liti.
