摘要(中) 本論文利用超塑成型(Superplastic-Forming, SPF)之延伸製程,快塑成型(Quick Plastic Forming, QPF)的製程應用於手持式製造業,手機之外殼金屬背蓋之零件的成型製造。由於在工業生產過程中,成型之總時間往往會影響生產之效率,對產業之生產成本花費也會有所影響。如何以最短的時間,獲得期望之外觀尺寸數據則為企業之目標,也是本篇論文所要探討的課題。本研究使用的材料為 AA5083 鋁合金板材。實驗主要探討吹製時間的不同,改變吹製工件鈑片的總時間,以及在不同的吹製壓力下,改變每一吹製壓力的吹製時間等等之參數進行實驗。並以量測工件鈑片之厚度、寬度長度分佈情形以及成型後外觀分析。綜合以上之驗證,可以找出成型工件之趨勢以及探討其對成型性的影響,並且以此完成最佳的吹製成型零件。 摘要(英) This paper uses Superplastic-Forming (SPF), Quick Plastic Forming (QPF) process for the manufacturing of hand-held manufacturing, the metal back cover parts of mobile phones. In the industrial production process, the total time of forming tends to affect the efficiency of production, and the production cost of the industry will also be affected. How to obtain the expected appearance size data in the shortest time is the goal of the enterprise, and it is also the topic to be discussed
in this paper. The material used in this study was AA5083 aluminum alloy sheet. The experiment mainly explores the difference in blowing time, changes the total time
of blowing the test piece of the workpiece, and changes the parameters of the blowing time of each blowing pressure under different blowing pressures. And to measure the thickness of the test piece of the workpiece, the width and length distribution of the test piece and the appearance analysis after forming. Based on the above verification, the trend of forming the workpiece can be found and the influence on the formability can be found, and the best blow molded part can be
