防護網之沖壓製程分析與連續模具設計

本文利用有限元素軟體進行板金沖壓成形製程模擬。針對特定製程的模具尺寸與板料利用HyperForm 進行有限元素模擬製程，其分析的道次分為兩道次，第一道次為左右兩側的彎曲預成形，第二道次為彎曲成形，透過有限元素分析軟體來分析板料在沖壓過程中應力應變分布情形與可能破裂位置之預測，作為日後進行實際生產製程評估。　　以實際開模的方式來驗證出分析所得的結果可行性，結果顯示模擬與實驗的誤差約為2%，可得知模擬與實驗之相似度頗為相近，可知其模擬具有相當可信度及參考性。

In this paper, we used the finite element software to analyze the sheet-stamping process. We used HyperForm to analyze the finite element simulation in the specific-process of die and sheet metal. There were two stages in the simulation process. The first stage was pre-bending at the zygomorphic of the product. The second stage was bending at the zygomorphic of the product. To used the finite element software to analyze the stress, the strain and the possible fracture location when the sheet metal was in the stamping process. It can estimate the real production process in the future. Used the real process to proof the result of the simulation. The simulation and experiment results show that the error was about 2%. We can know the result of the simulation and experiment was very similar. The simulation shown the reliability and reference.
