Mayankho a fakitale yopangira zitsulo zolimba kwambiri amatsekereza kusiyana pakati pa zopangira zida zachikhalidwe ndi kupanga - kuperekera magawo owoneka ngati ukonde okhala ndi makina apamwamba kwambiri, kutsika kwamphamvu, komanso kuwongolera kocheperako. Koma sizinthu zonse zoyambira zomwe zimatha kupanga zida za ma hydraulic valves, ma pampu othamanga kwambiri, kapena ma nozzles a alloy a cobalt omwe amapulumuka panjinga 200+ ndi ma abrasive fluid media. Tawona ma projekiti ambiri akuyimitsidwa pa siteji ya prototype - osati chifukwa cha mapangidwe olakwika, koma chifukwa theka olimba zitsulo kuponyera fakitale analibe kuwongolera zitsulo, kutsimikizira mkati, kapena kuphatikiza njira zosakanizidwa.
Chifukwa Chake Kuyimba Kwambiri Kumalephera - Ndipo Zomwe Zimagwira Ntchito
Zolephera zambiri zimachokera ku zifukwa zitatu: kusagwirizana kwa kutentha kwa slurry panthawi ya rheocasting, kusakwanira kwa tirigu mu slurry ya theka-olimba, kapena kusamvetsetsana pakati pa chipukuta misozi ndi kutsika kwa CNC Machining allowance. Kumalo athu ku Qingdao, timayeza kukhuthala kwa slurry munthawi yeniyeni pogwiritsa ntchito ma rheometer ozungulira - osati ma setpoint thermocouples. Tapeza kuti kupatuka kwa ± 1.5 ° C pamwamba pa 582 ° C mu AMS 5387 cobalt alloy slurry kumawonjezera kuchepa kwapang'onopang'ono ndi 23% m'makoma a silinda anyumba okhuthala kuposa 12 mm. Ichi ndichifukwa chake timayika chithunzi chotenthetsera mwachindunji mumanja ndikuwongolera liwiro la jakisoni mwachangu pagawo lililonse la geometry.
Chofunika kwambiri, kuponyedwa kwa theka-olimba sikuli kokha. Ndi mfundo mu unyolo wopangidwa molondola. Pampu ya pisitoni yoponyedwa mu semi-solid T800 cobalt alloy iyenera kusunga mawonekedwe okhazikika kudzera pakuwongolera kutentha kochepetsera nkhawa * isanakwane* milling ya ma axis asanu a ma valve port contours. Ngati nyumba yoponyerayo siyikuwongolera kuzizira mkati mwa ± 3 ° C / min kuchokera ku 1050 ° C mpaka 600 ° C - kapena ngati alibe chitsimikiziro cha GD&T cholumikizidwa ndi CMM pamiyeso yobiriwira - gawo lomaliza lidzalephera kuyesa kukakamiza kwantchito. Timachita zonse ziwiri. Gulu lirilonse limaphatikizapo kusanthula kwa spectrographic, muyeso wa dendrite arm spacing (DAS) pansi pa SEM, ndi kufufuza kwathunthu kwa chipika chochizira kutentha.
Maluso Anayi Osakambirana pa Ntchito Zofunika Kwambiri
Fakitale yeniyeni yopangira zitsulo zolimba imayenera kupereka zambiri kuposa zitsulo zowoneka bwino. Iyenera kutsimikizira kugwira ntchito motsatira ndondomeko. Nazi zomwe timatsimikizira tisanatchule ntchito iliyonse:
- Kuwongolera kwamtundu wazinthu: Ingots yaiwisi ya cobalt-nickel yotengedwa kuchokera ku mphero zovomerezeka ku ASTM B575 ndi AMS 5737-ndi malipoti oyesa mphero amawunikiridwa motsutsana ndi mawonekedwe omwe akubwera.
- Njira-integrated metrology: In-line laser scanning of mold cavity pre-fill, post-ejection CMM kuyendera malo ovuta kwambiri, ndi mapu owoneka bwino a ndime zotuluka mkati musanayambe kukonza
- Ma hybrid kulolerana stacking: Timawerengera kuchuluka kwa zolakwika zomwe zikuchulukirachulukira pakuchepa kwapang'onopang'ono, kupotoza kwa kutentha, ndi kupotokola kwanjira yamitundu yambiri-osangogwiritsa ntchito ma generic ± 0.3 mm
- Protocol yovomerezeka yogwira ntchito: Nyumba iliyonse yokakamiza ya valve imayesedwa kutayikira kwa helium pa 1.5 × kukakamiza kugwira ntchito, kenako kutulutsa mchere pa ASTM B117 kwa maola 96 musanafike kulongedza komaliza.
Real-World Tradeoffs Muyenera Kuvomereza
Mainjiniya ena amaganiza kuti kuponya kolimba pang'ono kumangochepetsa ndalama. Sichoncho-pokhapokha ngati mukuyang'ana mabanja enaake. Kwa ma geometri okhala ndi mipanda yopyapyala, yovuta kwambiri ngati zodzigudubuza za winch center shaft zokhala ndi mano ophatikizika a spline ndi ma groove amafuta, semi-solid imachepetsa nthawi yopangira makina ndi 40% ndikuwongolera moyo wotopa ndi 2.7 × motsutsana ndi mchenga wofanana. Koma kwa flanges yosavuta pansi 50 mm wandiweyani? Kuyika ndalama mwachizolowezi nthawi zambiri kumapereka ROI yabwinoko.
Posachedwa tidagwira ntchito ndi European hydraulic OEM yomwe idaumirira kuti ikhale yolimba pa maziko a mpope a 320 mm. Kuyerekeza kwawo kunaneneratu 0.12 mm warpage. Tsamba lenileni la nkhondo linali 0.28 mm - chifukwa mtundu wawo sunawerengerepo kusintha kwakukulu panthawi ya jekeseni wa slurry mu nkhungu za ceramic. Tidayesa zoyeserera ndi ma geji ophatikizika, kulimba kwa pini, ndikuwonjezera zoziziritsa kuderako. Nkhondo yomaliza idatsika mpaka 0.14 mm. Kodi tikuphunzirapo chiyani? Kuyerekezera kumathandiza-koma pokhapokha ngati kukhazikika pamachitidwe otenthetsera.
Zomwe Mungafune Ku Factory Yanu Ya Semi Solid Metal Casting
Funsani mafunso awa musanasaine NDA:
- Kodi mungandiwonetse ziphaso zanu zomaliza za AMS 5387—kuphatikiza makonda a DAS ndi mamapu a tsankho la interdendritic?
- Kodi mumachita kuyesa kwa akupanga pamapangidwe okhuthala kuposa 25 mm - kapena kungoyang'ana komaliza?
- Kodi mumalipira bwanji kusagwirizana kwakukula kwamafuta pakati pa zoponya za T800 ndi zoyika zitsulo zosapanga dzimbiri pakuphatikiza?
- Kodi chiwongola dzanja chanu chapakati pa GD&T ndi chiyani chomwe chimafuna kulolerana ndi 0.05 mm?
Ngati mayankho sakumveka bwino, akuchedwa, kapena akuti "zochita zamakampani," chokanipo. Kulondola sikukambidwa - kumapangidwa, kuyezedwa, ndikulembedwa pa sitepe iliyonse.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito fakitale yopangira zitsulo zolimba pomwe zigawo za mpope za cobalt-alloy zimakumana ndi zovomerezeka za ISO 9001-certified workflows, osati kungoponya zida. Sitimalekanitsa kuponya kuchokera ku makina - timawapeza pamodzi. Sitiwona zolemba zakuthupi ngati zolemba - timazitsimikizira ndi kutentha kulikonse. Ndipo sitilonjeza "zolondola." Timatsimikizira - gawo ndi gawo, gulu ndi batch, kasitomala ndi kasitomala. Chifukwa m'ma hydraulic system, mavavu amafuta & gasi, ndi ma drivetrains a injiniya, palibe malire pakuyerekeza. Pali kungochita-kapena kulephera.
