鎂合金3C產品浮花壓製混合製程成形性之研究
摘要
本研究主要在於探討AZ31鎂合金薄板以浮花壓製法壓製具凹凸造型製品之加工成形性。首先，利用有限元素分析軟體DEFORM進行模擬，模擬在各種製程參數變化下之浮花壓製成形特性，本研究模擬之製程參數包括模具圓角、定剪摩擦因子、拔模斜度及浮花壓痕深度等參數。藉由各種不同製程參數之變化，探討浮花壓製成形時所需之成形負荷與具凹凸造型圖案之完整性。其次，以模擬參數之一組數據實際製作成模具，進行鎂合金浮花壓製實驗，將模擬結果與實驗結果進行比較以驗證模擬結果之準確性。最後，藉由硬度試驗及金相觀察，來評估鎂合金壓印成品，在不同的溫度下對於鍛造零件之強度及顯微組織之影響。

This study investigates the formability of AZ31 magnesium alloy sheet when pressing the product with concave and convex shapes by embossing process. Firstly, finite element software DEFORM is applied to simulate the effect of process parameters on forming characteristics under embossing process. Process parameters considered in the study includes die radius, constant friction factor, draft angle and indentation depth of embossing. By the changes of process parameters, the forming loads and completeness of die pattern with concave and convex shapes are discussed. Secondly, take one set of simulated parameters to fabricate an experimental die, embossing experiments are carried out by using magnesium alloy sheet, the experimental results are compared with the simulated results to prove the accuracy of simulation model. Finally, from the measurement of hardness and metallographic observation of embossed part, the influence of forming temperatures on the strengths and microstructures of magnesium alloy sheet under embossing process can be evaluated.
