Pamene mainjiniya afotokoza ndalama kuponyera silikoni Sol foundry fakitale Kuthekera kwawo, sakungoyang'ana wowathandizira - akufunafuna kukhazikika kwapang'onopang'ono chifukwa cha kupsinjika kwamafuta, kusasinthika kwapampu yamakilogalamu 50 a cobalt alloy, ndi zero kulolerana kwa porosity m'matupi a valve a AMS 5387. Ndicho chenicheni chogwirira ntchito chomwe timachiwona tsiku ndi tsiku ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.-wopanga Qingdao-based pamene "silicone sol" si mawu omveka; ndi makina omangira omwe amakhala ndi 12-micron pamwamba polekezera pa T800 aloyi nozzles pamaso dewaxing.
Taponya zida zopitilira 17,000 za cobalt-nickel kuyambira 2019-chilichonse chimatsatiridwa ndi batch, kuchuluka kwa kutentha, ndi lipoti loyendera CMM. Mu projekiti ina ya North America hayidiroliki OEM, pisitoni pampu yamphamvu nyumba analephera katatu ndi mpikisano silica-boma chipolopolo: microcracks anapanga pa nthunzi dewaxing chifukwa molakwika matenthedwe kukula pakati pa ceramic chipolopolo ndi T800 aloyi pachimake. Mapangidwe athu a silicone sol, ochiritsidwa pa 180 ° C m'malo mwa 120 ° C, adachepetsa kupsinjika kotsalira ndi 41% - kutsimikiziridwa kudzera mu kusanthula kwa mayendedwe a XRD lattice. Izo si chiphunzitso. Ichi ndichifukwa chake makasitomala amatitumizira zojambula zolemera za GD&T zokhala ndi ± 0.015 mm zodziwika bwino komanso kuyembekezera kuvomerezedwa ndi nkhani yoyamba.
Chomwe chimasiyanitsa chowonadi ndalama kuponyera silikoni Sol foundry fakitale kuchokera kwa woyimba wamba? Zitatu zomwe sizingakambirane: Choyamba, kuwongolera zinthu zopangira. Timangopeza ma ingots ovomerezeka a AMS 5387 a cobalt alloy okhala ndi malipoti athunthu oyesa mphero - osati ziphaso zokha. Chachiwiri, kutsimikizira chilungamo cha zipolopolo. Gulu lililonse la zipolopolo limayesedwa kulimba kwamphamvu pa 1,150 ° C lisanatsanulidwe. Chachitatu, maphunziro a geometry a postcast. Zigawo za mchenga zimachepa mosadziwika bwino; zoponyera ndalama pogwiritsa ntchito silikoni sol zimachepa mkati mwa ± 0.12% - koma pokhapokha mutawongolera kukula kwa sera, chinyezi chowumitsa zipolopolo (≤35% RH), ndi kuchuluka kwa njira zowombera. Timalemba zonse zitatu mu nthawi yeniyeni.
- Kupambana kwazinthu kupitilira mapepala apadera: Sitimangopanga "njira" T800-tikudziwa kuti malo ake osungunuka a eutectic amasintha 23 ° C pamene chromium imatsika 0.4%. Ichi ndichifukwa chake ma thermocouples athu amawunikidwa tsiku lililonse motsutsana ndi miyezo yotsatiridwa ndi NIST.
- Palibe makina a "black box": Chitsulo chilichonse kapena chitsulo chosapanga dzimbiri chimapita molunjika kuchokera ku chipolopolo kupita ku CNC-palibe kutentha kwapakatikati pokhapokha ngati kutchulidwa. Chifukwa chiyani? Chifukwa makina athu a m'nyumba a 5-axis amakhala ndi ± 0.008 mm kulondola kwa malo pa maziko a mpope wa 300-mm-diameter, kuchotsa zolakwika zokonzanso.
- Traceability yomwe imayamba musanathire: Chigawo chilichonse chimakhala ndi tag yokhala ndi QR yolumikizana ndi ma cert, zipolopolo zomangira zipolopolo, zokhotakhota kutentha, ndi malipoti omaliza a CMM-zonse zimapezeka kwa makasitomala kudzera pa portal yotetezeka.
Ena atha kunena kuti silicone sol ndiyochulukira pamathamanga apakatikati. Koma taganizirani izi: Wopanga zida zopangira mafuta ku Southeast Asia anafunikira mayunitsi 220 a pulagi ya alloy ya cobalt yosagwirizana ndi muyezo. Ochita nawo mpikisano adatchulapo mchenga-kenako adawonjeza $14,000 kuti asinthe mawonekedwe pambuyo pa gawo loyamba la gawo loyamba. Tinapereka chilolezo choyamba pogwiritsa ntchito zipolopolo za silicone sol, zomwe zimakhala ndi makulidwe a khoma mpaka ± 0.18 mm kudutsa zigawo za 120 mm. Mtengo wa Delta? 7.3% apamwamba pa unit iliyonse - koma 100% yocheperako kukonzanso zomangamanga, ziro zidutswa, ndi kutumiza masiku 19 pasadakhale. Kuponyera mwatsatanetsatane sikungopeŵa makina-ndikuwongolera komwe kukuchitika komanso kuchuluka kwa makina.
Yang'anani zam'tsogolo: Tikukulitsa luso lathu la silicone sol kuti liphatikizepo kuponyera kwa ma hybrid pafupi-net-shape cast + EDM yolondola ya mayendedwe ozizirira mkati m'matupi othamanga kwambiri - zomangira zosatheka kubowola positi. Koma chofunika kwambiri masiku ano sichinasinthe: kupereka ma valve opanikizika omwe amasindikiza pa bar 420 popanda kutayikira, nyumba zopopera zomwe zimakhala ndi moyo wa maola 15,000 mu slurry ya abrasive slurry, ndi ma winch center shaft rollers okhala ndi ma gradients olimba omwe amatsimikiziridwa ndi mapu a micro-Vickers. Ngati ntchito yanu ikufuna kukhulupirika kobwerezabwereza - osati "kungosindikizidwa" - ndiye kumanja ndalama kuponyera silikoni Sol foundry fakitale sizimatanthauzidwa ndi masikweya makwerero kapena kutulutsa kwapachaka. Zimatanthauzidwa ndi kagawo kakang'ono ka pore komwe gawo lanu lofunikira limatha kupirira ...
