Xa iinjineli zichaza utyalo-mali lokugalela i-silicone ye-sol Foundry factory Izakhono, abakhangeli nje umboneleli-bafuna uzinzo lwe-dimensional phantsi koxinzelelo lwe-thermal, ukuhambelana kwe-microstructural kwi-50-kg yezindlu zempompo ye-cobalt alloy, kunye nokunyamezelwa kwe-porosity kwi-AMS 5387 imizimba yevalve. Leyo yinyani yokusebenza esiyibona imihla ngemihla kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.-umvelisi wase-Qingdao apho "i-silicone sol" ingekho i-buzzword; yinkqubo yokubopha ebamba ukunyamezelana komphezulu we-12-micron kwimilomo yengxubevange ye-T800 ngaphambi kokuba ikhutshwe.
Siphose izinto ezingaphezu kwe-17,000 ze-cobalt-nickel ukusukela ngo-2019-nganye ilandelelwe ibhetshi, inombolo yobushushu, kunye nengxelo yokuhlolwa kweCMM. Kwiprojekthi enye ye-OEM yaseMntla Melika, i-piston pump cylinder yendlu ayiphumelelanga kathathu ngeqokobhe le-silica-bonded ekhuphisanayo: ii-microcracks ezenziwe ngexesha lokuthotywa komphunga ngenxa yokwandiswa kwe-thermal ngendlela engafanelekanga phakathi kweqokobhe le-ceramic kunye ne-T800 alloy core. Ukuqulunqwa kwethu kwe-silicone sol, ephiliswe kwi-180 ° C endaweni ye-120 ° C, kuncitshiswe uxinzelelo olushiyekileyo nge-41% -ukuqinisekiswa ngohlalutyo lwe-XRD lattice strain. Ayiyothiyori leyo. Yiyo loo nto abathengi besithumelela imizobo ye-GD & T-enzima kunye ne-± 0.015 mm yee-callouts eziyinyaniso-kwaye ulindele ukuvunywa kwenqaku lokuqala.
Yintoni eyahlula inyaniso utyalo-mali lokugalela i-silicone ye-sol Foundry factory ukusuka kwi-caster yenjongo jikelele? Izinto ezintathu ezingenakuxoxisana: Okokuqala, ulawulo lwempahla ekrwada. Sifumana kuphela i-AMS 5387 cobalt alloy ingots eziqinisekisiweyo ezineengxelo ezipheleleyo zovavanyo lokusila-hayi nje izatifikethi zokuthotyelwa. Okwesibini, ukuqinisekiswa kwengqibelelo yeqokobhe. Ibhetshi nganye yeqokobhe ivavanywa ngamandla ashushu kwi-1,150°C phambi kokuba igalelwe. Okwesithathu, uqeqesho lwejometri yasemva kokuphoswa. Amalungu e-Sand-cast ayancipha ngokungalindelekanga; ukuchithwa kotyalo-mali kusetyenziswa i-silicone sol shrink ngaphakathi ± 0.12%-kodwa kuphela ukuba ulawula ukwandiswa kwepatheni ye-wax, i-shell drying humidity (≤35% RH), kunye namazinga okudubula okudubula. Singena sobathathu ngexesha lokwenyani.
- Ubuchule bezinto eziphathekayo ngaphaya kwamaphepha athile: Asazi nje "inkqubo" ye-T800-siyazi indawo yayo yokunyibilika kwe-eutectic itshintsha i-23 ° C xa i-chromium ihla nge-0.4%. Yiyo loo nto i-thermocouples yethu yomlilo ilinganiswa yonke imihla ngokuchasene nemigangatho elandelekayo ye-NIST.
- Akukho mashini "ibhokisi emnyama": Yonke intsimbi okanye intsimbi engatyiwayo iya ngqo ukusuka ekuqhawukeni kweqokobhe ukuya kwi-CNC-akukho bushushu obuphakathi bokuphatha ngaphandle kokuba kuchaziwe. Ngoba? Ngenxa yokuba oomatshini bethu bangaphakathi be-5-axis babambe ± 0.008 mm ukuchaneka kwendawo kwiziseko zempompo ze-300-mm-diameter, ukuphelisa iimpazamo zokulungiswa kwakhona.
- Ukulandeleka okuqala ngaphambi kokugalelwa: Iqashiso ngalinye liphethe ithegi enekhowudi ye-QR enxibelelanisa kwii-certs zezinto, iqokobhe lokwakha izingodo, i-curves yobushushu egalelwe, kunye neengxelo zokugqibela ze-CMM-zonke zifikeleleka kubathengi nge-portal ekhuselekileyo.
Abanye banokuphikisa ukuba i-silicone sol igqithise kakhulu kwimitsi ephakathi. Kodwa khawucinge ngoku: Umakhi wezixhobo zeoli ekuMzantsi-mpuma Asia wayefuna iiyunithi ezingama-220 zeplagi yealloyi yecobalt engekho semgangathweni. Abakhuphisana bacaphula ukuphosa isanti-emva koko bongeza i-$ 14,000 yokulungiswa kwepateni emva kokuhamba kwenqaku lokuqala. Sihambise imvume yokuqala sisebenzisa amaqokobhe e-silicone sol, kunye nokwahluka kobukhulu bodonga olugcinwe kwi-± 0.18 mm kumacandelo angama-120 mm. I-delta yexabiso? I-7.3% ephezulu kwiyunithi nganye-kodwa i-100% engaphantsi kobunjineli bokusebenza kwakhona, i-zero scrap, kunye nokuhanjiswa kweentsuku ze-19 ngaphambi kweshedyuli. Ukwenziwa ngokuchanekileyo akukho malunga nokuphepha ukwenza oomatshini-kumalunga nokulawula ukuba kuphi kwaye kungakanani ukwenziwa komatshini.
Jonga kwixesha elizayo: Sandisa amandla ethu e-silicone sol ukubandakanya i-hybrid kufuphi-net-shape casting + i-EDM echanekileyo yeziteshi zokupholisa zangaphakathi kwimizimba yevalve ephezulu-izakhiwo ezingenakwenzeka ukubhola i-post-cast. Kodwa eyona nto iphambili namhlanje ayitshintshanga: ukuhambisa iivalvu zoxinzelelo ezitywina kwibhari engama-420 ngaphandle kokuvuza, izindlu zempompo ezisinda kubomi benkonzo yeeyure ezingama-15,000 kubudaka oluludaka, kunye ne-winch center shaft rollers ezinobunzima obungqinwa yi-micro-Vickers mapping. Ukuba isicelo sakho sifuna ingqibelelo ephindaphindwayo yesinyithi-hayi nje "ukuphoswa ukuprinta" - ke ilungelo utyalo-mali lokugalela i-silicone ye-sol Foundry factory ayichazwanga ngokuboniswa kwesikwere okanye imveliso yonyaka. Ichazwa ngowona mthamo umncinci wepore icandelo lakho elibalulekileyo elinokunyamezela… kunye nenkqubo yoqeqesho ukuyiqinisekisa.
