Pamene mainjiniya afotokoza fakitale yopangira utomoni mchenga ntchito zopangira zitsulo zolimba kwambiri, sikuti zimangoyitanitsa magawo - zimateteza kukhazikika kwapang'onopang'ono panjinga yotentha, kusasunthika kwa microstructural kudutsa 100-kg castings, ndi zero kulolerana kwa porosity m'malo opanikizika. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., taponyera nyumba zopitilira 27,000 za cobalt-nickel kuyambira 2019-iliyonse imayang'aniridwa ndi ma Zeiss CMM omwe ali ndi ISO 10360-2-ndipo adazindikira kuti mchenga wa utomoni si njira yobwerera. Ndi njira yokhayo yothandiza ya ma geometries ovuta ngati nyumba za silinda ya piston pomwe kuponya ndalama kumawononga denga ndipo mchenga wobiriwira umalephera kumapeto.
Chifukwa Chake Kuponyera Mchenga Kumapambana Pazigawo za Mission-Critical Hydraulic & Pump
Magulu ambiri ogula zinthu amaganiza kuti mchenga wa utomoni ndi "wocheperako" kuposa kuponya ndalama. M'malo mwake, tikuwona zosiyana: poponyera ma AMS 5387 cobalt alloy nozzles pamapampu amafuta akunyanja, mchenga wa silika wopangidwa ndi utomoni umapereka kulolerana kwa mzere wa 0.3 mm pama diameter a 420-mm-olimba kuposa momwe kusiyanasiyana kwachipolopolo kumalola. Mfungulo yake? Analamuliridwa exothermic anachita pa kuchiritsa. Malo athu amagwiritsa ntchito zomangira za phenolic urethane zomangira amine, osati zachikhalidwe za furan. Izi zimachotsa kujambula kwa sulfure mu cobalt alloys, kusunga kukana kwa dzimbiri m'malo a H₂S. Tayesa 12% kutsika kwa intergranular m'mapulagi opangidwa ndi T800 pambuyo pa kuyesedwa kwa NACE TM0177 kwa maola 72-kumangiriridwa mwachindunji ndi binder chemistry, osati chithandizo cha kutentha pambuyo poponyedwa.
Izi ndizofunikira chifukwa ma hydraulic valve matupi salephera kulakwitsa kwakukulu. Amalephera kuchoka ku micro-shrinkage polumikizana pakati pa zigawo zokhuthala ndi zoonda-monga momwe doko lothandizira kupanikizika limakumana ndi flange yokwera. Akatswiri athu opanga mapu amapangira ma gradients otenthetsera pogwiritsa ntchito zoyeserera za MAGMASOFT® * asanavomerezedwe. Timasintha ma resin-to-mchenga ma ratios potengera zone: 1.8% binder muzoyika zapakati, 1.2% m'makoma akunja nkhungu. Zotsatira zake? 94% zokolola zoyamba zoyamba pazinyumba za silinda zapampu za piston motsutsana ndi pafupifupi 71%.
Kuphatikiza Koyima Kumathetsa Vuto la "Casting-Machining Handoff".
Zolephera zambiri sizimachitika pakupanga kapena kupanga makina, koma komwe amakumana. Makasitomala adatitumizirapo chojambula cha winch center shaft roller yokhala ndi ± 0.025 mm kuzungulira kwa 120-mm OD. Wowagulitsa m'mbuyomu adaponya, kenako adatumizidwa kusitolo yachitatu ya CNC. Chogudubuzacho chinapotoza 0.08 mm panthawi yochepetsera nkhawa chifukwa chotsalira chotsaliracho sichinapangidwe mapu asanapange makina. Timachita izi mosiyana: akatswiri athu a metallurgists amayesa mayeso othamanga pa ladle iliyonse, kenaka amadyetsa zowunikira zambewu mu makina athu a Mazak INTEGREX i-200S amitundu yambiri. Timapanga makina mkati mwa maola 48 a shakeout - osachedwetsa kukalamba - pogwiritsa ntchito njira zomwe zimatsata ma vectors opsinjika. Kuzungulira komaliza: 0.018 mm. Mosasintha.
Kuphatikiza uku kumafikira ku kufufuza kwazinthu. Gulu lililonse la T800 alloy limakhala ndi tikiti yotentha ya QR yolumikiza ma certs (ASTM A995 Grade 6A), malipoti osungunuka, ndi mbiri yomaliza yoyendera. Palibe zipika zamapepala. Palibe kulowa pamanja. Ngati maziko a mpope alephera m'fakitale yochotsa mchere kum'mwera chakum'mawa kwa Asia, timalekanitsa makilogilamu 3.2 enieni a zitsulo zosungunuka zomwe zimagwiritsidwa ntchito-ndi kukokera mbiri yake yotentha kuchokera munkhokwe yathu ya Siemens SIMATIC PCS 7 DCS.
Zochepa Zenizeni Zapadziko—ndi Momwe Timagwirira Ntchito Mkati Mwazo
Kuponyera mchenga wa resin kuli ndi malire olimba. Sitingatchule magawo omwe ali ndi makulidwe a khoma pansi pa 8 mm mu cobalt alloys - chiopsezo chodzaza nkhungu chosakwanira chimaposa 40%. Komanso sitidzavomereza kuyitanidwa kwa GD&T komwe kumafunikira malo enieni olimba kuposa ± 0.1 mm pazinthu zopitilira 150 mm kuchokera pamadatum osawonjezera malo opangidwa ndi makina patani. Ena anganene kuti kupanga CNC-kokha kumapewa zovuta izi. Koma kupanga chitsulo cholemera makilogalamu 65 kuchokera ku mipiringidzo yolimba kumawononga 3.7 × zambiri ndikuwononga 68% ya zinthu ngati tchipisi. Njira yathu yosakanizidwa - kuponyera mwatsatanetsatane + kumalizitsa kwa CNC - imadula nthawi yotsogolera ndi 40% pamisonkhano yamapampu a injiniya pomwe ikugwira 0.05 mm kutsika pazitsulo za 500-mm.
Timalemba zopatuka kulikonse. Kota yatha, kasitomala waku Europe adapempha 0.01 mm roughness pamwamba pa nkhope ya cobalt alloy plug. Mayeso athu adawonetsa Ra 0.8 µm. M'malo molonjeza zotsatira zomwe sizingatheke, tidakonza kupukuta kwa electrochemical post-machining-kuwonjezera $14.30/gawo koma kupereka Ra 0.05 µm. Kuwonekera kumaposa chiyembekezo nthawi zonse.
Kusankha Fakitale Yanu Yoponyera Mchenga wa Resin Sizikhudza Mtengo-Ndi Za Umwini Wanu
Ufulu fakitale yopangira utomoni mchenga ali ndi unyolo wonse: sayansi yazinthu, fizikiki ya nkhungu, kutsimikizika kwazitsulo, ndi kuyesa magwiridwe antchito. Ku QINGDAO QIANGSENYUAN TECHNOLOGY, timakana zojambula zopanda mawu a GD&T-tidzakuthandizani kuwatanthauzira. Timabweza mayankho a DFM mkati mwa maola 72, kuyika zoopsa ngati zokwera zakhungu m'malo ovala kwambiri kapena kusakwanira kokwanira pamayendedwe ozizirira amkati. ISO 9001: Dongosolo lathu la 2015 silimalemba - limakhala kutsatira Cpk pamiyeso yovuta kwambiri, yokhala ndi zidziwitso zodziwikiratu pamene kuthekera kwantchito kutsika pansi pa 1.33.
Makasitomala apadziko lonse lapansi amasankha ife chifukwa timatumiza zida zogwirira ntchito-osati zojambula zokha. Valavu iliyonse yamagetsi imayesedwa 100% hydrostatic pa 1.5 × ovotera kupanikizika kogwira ntchito. Nozzle iliyonse ya cobalt alloy imadutsa pakuwunika kolowera utoto pa ASTM E165. Sitibisala kumbuyo kwa "kutsata." Tikukuwonetsani lipoti loyesa nambala yanu ya seriyo.
Ngati pulojekiti yanu yotsatira ikufuna zitsulo zazitsulo zomwe zimapulumuka 20,000 psi cycle, kukana slurry abrasive, kapena kusunga kuyanjanitsa pambuyo pa zaka 10 pansi pa nthaka - yambani ndi fakitale yopangira mchenga yomwe imagwiritsa ntchito zitsulo monga engineering, osati luso.
