| dc.description.abstract | 緣由-鋁片的截面厚度均勻分布度一直是重要的一個吹製結果，與
成型後的鈑片強度、吹製成功率，有著重要連結關係，而影響截面厚度
分布均勻度又與以下幾項重要設計與實驗參數有莫大的關係，分別為 1.
沖頭的幾何形狀 2.沖頭引伸的深度 3.材料加工溫度 4.模具夾持力道的
大小 5.鈑片介於氣密環外成型摩擦力 6.脫模劑。
本論文主要以兩階段超塑成型(Quick Plastic Forming)之工法應
用於手機外殼製為研究方向(實驗吹製前 30 秒設計兩階段夾持，在夾持
力 3 頓(小於正常鎖模力 4.2 頓)情況下調整氣壓各為 0.5、1、1.5mpa
各吹製 10 秒)主要目的為探討兩階段造成的內拉夾持造成的收縮，是否
有助於提升鈑片截面厚度平均分布度。藉由兩階段夾持力降低鋁鈑和模
具間摩擦力來增加內拉力，將探討以下三項參數對內拉力的影響，1.兩
階段成型 2.鈑片面積長寬比差異性 3.塗抹脫模劑
最後將以 5083 1mm 鋁鈑材實驗吹製，做截面度的厚度分布度比
較，試圖尋找最佳化截面厚度吹製參數，最後再應用於較成型較困難的
5052 材料。

| dc.description.abstract | The cause-aluminum sheet cross-section thickness uniformity has always been an important blowing result，and after the molding sheet strength，blowing success rate，has an important link relationship，and affectther of the uniformity of cross-section thickness distribution and the following important design and experimental parameters have a great relationship，The geometry of the punch 2. Depth of the punch extension 3. Material processing temperature 4. The size of the mold clamping force channel 5.
Sheet sheet is between the extensosiring friction 6. This paper mainly applies the two-stage superplastic forming (Quick Plastic Forming) method to the mobile phone housing system for the research direction (30 seconds before
the experimental blow-up design two-stage clamping， in the case of clamping force 3 tons (less than the normal lock force 4.2)， adjust the air pressure of 0.5， 1， 1.5mpa blow 10 seconds) is mainly intended to explore whether the shrinkage caused by the two-stage internal pull grip can
help to increase the average distribution of sheet sheet section thickness thickness.
By reducing the friction between aluminum sheet sheet and mold to increase the internal pull force by two-stage clamping force，the effect of the following three parameters on the internal pull will be explored，1. Twostage forming 2. Sheet sheet area aspect aspect ratio difference 3. Apply ingress excitate iv Finally，it will be 5083 1mm aluminum sheet metal experimental blowing，to do cross-sectional thickness distribution comparison，trying to
find optimized cross-section thickness blowing parameters，and finally applied to the more difficult molding 5052 material. | en_US |
