本文使用有限元素法模擬喇叭端子零件之多道次引伸製程,使用彈塑性模式的殼元素作引伸製程分析模擬。在金屬薄板成形製程中,引伸是應用相當廣泛的製程。本文針對厚度為0.5mm的黃銅C2680作拉伸試驗來獲得相關的材料機械性質參數作為有限元素分析的設定,並將電腦模擬結果與現有模具生產成品之厚度分佈作比對。另外,使用田口方法對第一引伸道次作分析參數設定,以板件最大變薄比作為品質特性;其中的控制因子有沖頭圓角、母模圓角、潤滑條件與模具間隙。結果顯示模具圓角對引伸製程的影響最大,其次為沖頭圓角、模具間隙與潤滑條件。經實務驗證,本研究之模擬設定方法可作為連續引伸模具設計之參考。
In this research, finite element analysis method is used to simulate the multi-stage deep drawing processes of a connecting component, i.e. loudspeaker terminal. Based on tensile test, the material properties of copper C2680 with 0.5mm in thickness and the shell elements for elasto-plastic analysis method are used for the finite element simulations. The simulation result of the distribution of wall thickness was compared with the strip of the product manufactured by an existing progressive die. In addition, Taguchi method has been used to compare the influences of control factors based on the maximum thinning ratio as the quality characteristic. Four control factors are considered in this study; they are punch radius, die radius, lubricant and the clearance of die. The result showed that die radius is the most important influence factor in deep drawing process, followed by punch radius, clearance of the die and lubrication. The simulation model proposed in this thesis can be used for the design of the drawing process of a progressive die for a copper sheet component.
