摘要
本論文針對光電零件之雷射二極體冷間鍛造製程模擬研究 ，以沖鍛後凸柱高度和原胚料厚度之關係 ，成形過程中材料之流動方式 ，及鍛造負荷等為指標 ，探討胚料尺寸對與沖頭幾何形狀等製程參數對成形性的影響。本研究利用有限元素法分析軟體DEFORM V3.2模擬板材在油壓機上之冷間鍛造製程 ，探討不同胚料與沖頭幾何形狀對凸柱高度之影響 ，並觀察材料之流動方式 ，以分析出製程參數影響凸柱高度成形之原因 ，最後依照模擬所獲得之結果 ，製作模具並進行實驗來驗証有限元素法分析之正確性。

The press forging process of laser diodes was studied in the present study. In the press forging process, a sheet blank made of spec steel is fanned into the part shape in which a boss of certain height is required. In order to examine the effect of process parameters, such as sheet blank size and punch shape, on the formability of boss height, the finite element software DEFORM V3.2 was employed to simulate the press forging processes, using the relations between boss height and blank thickness, material flow pattern, and forging load as forming index. By a systematic analysis of the simulation results, an optimal die design was proposed with the use of a thinnest sheet blank. The proposed die design was validated by experiments and the accuracy of the finite element analysis was then confirmed.
