近日，機(ji)(ji)械科學研究總(zong)院北京機(ji)(ji)電(dian)研究所(suo)承(cheng)擔的“輕合金(jin)精密流動控制成形成套(tao)技術開(kai)發(fa)及應用示(shi)范項目”順利(li)通過(guo)成果鑒定。
該(gai)項目在(zai)國(guo)(guo)(guo)內(nei)(nei)(nei)率先通過數(shu)值模擬和(he)工(gong)藝(yi)實驗，研(yan)究(jiu)了輕合(he)(he)金(jin)流動控制(zhi)(zhi)成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)的機理，總結出背壓(ya)力對成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)載荷及成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)件質量(liang)的影響(xiang)規律，掌握了流動控制(zhi)(zhi)成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)關鍵工(gong)藝(yi)參數(shu)，填補了國(guo)(guo)(guo)內(nei)(nei)(nei)該(gai)項技術研(yan)究(jiu)的空白；開發了具(ju)有自主知識產(chan)(chan)權的國(guo)(guo)(guo)內(nei)(nei)(nei)首(shou)套(tao)(tao)渦(wo)旋盤流動控制(zhi)(zhi)成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)模具(ju)；制(zhi)(zhi)定了國(guo)(guo)(guo)內(nei)(nei)(nei)首(shou)套(tao)(tao)渦(wo)旋盤流動控制(zhi)(zhi)成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)工(gong)藝(yi)規程，設計制(zhi)(zhi)造了國(guo)(guo)(guo)內(nei)(nei)(nei)首(shou)臺輕合(he)(he)金(jin)流動控制(zhi)(zhi)成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)壓(ya)力機；建成(cheng)(cheng)(cheng)(cheng)(cheng)國(guo)(guo)(guo)內(nei)(nei)(nei)目前唯一(yi)的輕合(he)(he)金(jin)流動控制(zhi)(zhi)成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)生產(chan)(chan)線，形(xing)(xing)(xing)(xing)成(cheng)(cheng)(cheng)(cheng)(cheng)了年產(chan)(chan)100萬套(tao)(tao)渦(wo)旋盤等復雜(za)輕合(he)(he)金(jin)成(cheng)(cheng)(cheng)(cheng)(cheng)形(xing)(xing)(xing)(xing)件的生產(chan)(chan)能(neng)(neng)力，加(jia)快了我(wo)國(guo)(guo)(guo)汽(qi)車(che)節(jie)能(neng)(neng)型(xing)空調的國(guo)(guo)(guo)產(chan)(chan)化進程。
鑒定委員會專(zhuan)家認為(wei)此項(xiang)技術為(wei)國內首(shou)創，整體技術達到國際(ji)先進水平，建議成果推(tui)廣。
