本研究之車用喇叭座所應用到的技術範圍為多道次引伸及沖孔等傳送沖模技術,利用傳送技術開發出車用喇叭座之產品,選擇SPCC冷軋鋼板為開發模具之材料,來研究關於引伸成形製程及模具設計。 本研究採用板金成形分析軟體HyperFormSolista做為輔助設計之工具,透過CAE分析軟體確認各工程道次之製程參數,再利用VISI沖壓設計軟體進行模具開發,進而有效減少實際測試、修模次數,達到降低成本之目的。 結果顯示,本研究之工程設計依據引伸率設計準則,共規劃為下料、引伸1、引伸2、引伸3、引伸4、印花、沖孔、沖字、修邊等共8道次。依上述結果進行模具設計與製作,於實際引伸成形作業後將成品進行量測,結果成品尺寸符合原設計圖面要求。
In this study, the expertise ambits of car-horn-base were the multi-pass drawing, punchingand the transfer die technology. We used the transfer technology to develop the product of car-horn-holder. We chose the cold-roll-steel, SPCC to be the material of the develop product. We researched about the forming of drawing process and the design of die. In this study, we used the analysis software of sheet forming, HyperFormSolista to be the Computer-Aided -Engineering. We used the CAE analysis software to sure the process parameters of each process. Then, used VISI stamping-design-software to develop the die. We further reduced the frequency of trial die and the frequency of repair die to get purpose of the cost down. The results show that the design of engineering according to the design criteria of Drawing ratio , we designed eight processes, blanking, drawing-1, drawing-2, drawing-3, drawing-4, press, punching, punching-word, trim. According the results to design the die and manufacture. After the real drawing process, measure the final product. The results show that the dimensions of the product were all conform with the drawing request.
