"本研究計畫係建立一液壓式之機構用以產生液壓，以此液壓來進行擺線齒輪之精密下料 (Fine blanking)，並在下料過程中進行最佳化設計之研究。本計畫設計之液壓系統可分兩項:一項用來加壓V型環之液壓，另一項則用來加壓退料板間之液壓。本法和傳統式之精密下料最大不同處，在於V型環之位置，本法係將V型環置於工件上而非傳統式精密下料之導板上(Ejector chamber )。除此之外，退料板間亦供給均勻之液壓而不是只供給退料用之力而已。本計畫之V型環除採用傳統之圓形外，曲線形之V型環亦被採用來探討較複雜外形成品下料之光亮面影響。因此，擺線齒輪(Cycloid gear)之下料是被採用來驗證本計畫之可行性。除此之外，本計畫採用田口實驗法(Taguchi experimental method)為最佳製程設計之方法，來探討其最佳之加工參數(Process factors)諸如: Ｖ型環槽之形狀、位置、深度與角度、V型環和逆壓板之液壓大小。本法因V環是加工於料片上，而不是在模具上；因此，本法除加工簡易外，亦可大量減少實驗經費，亦可增加模具之壽命並有利於胚料成形。此外，本法也可避免傳統下料(一般下料和精密下料)常遇之問題，諸如:噪音震動(Noise)、刀具之磨損、成品的精度、高溫度對刀具和成品效應等問題。本計畫之成果除可提供模具製造業界新的下料技術參考外，亦可供學界在下料領域新的研究方向。""Fine hydro-mechanical blanking with V-type cavity on the work pieces are studied on the optimization considerations. The ejector chamber and V-type cavity on the surface of work pieces are pressurized by the hydraulic pressure. The influence of process factors for the length of the cutting surface about cycloid gear will be studied based on the method of Taguchi experimental method. The shape, position, depth and angle of V-type cavity and the magnitude of hydraulic pressure in V-ring and ejector chamber are investigated for the designs of their process factors. The proposed technique can give a more efficient and potentially cheaper than the conventional fine-blanking on the experimental works. The achievements obtained from the project will not be only provided to the use of sheet blanking industry but also for the applications of academic researchers."
