連續模具設計開發與製作之可行性分析
Design and Production Feasibility Analysis for Progressive Staimping Die
摘要
本論文以接地端子為沖壓成型件設計連續模具，以成本做考量並詳細規劃設計流程，從各模板設計，沖頭設計，模具設計，到選用各種加工方式，並以選用的材料，加工方法，五金零件去計算模具成本，模具製作完成後進行試模與調機，最後在沖壓過程中探討模具維修的問題，如沖頭斷裂、沖頭鈍化、卡料、毛邊異常等。 連續模具以接地端子為沖壓成型件進行沖壓，並輔以接地端子設計複合模具，進行兩者比較。條件設定以產量30萬，人工一位，每天八個小時，一周五天，進行模具成本、日生產量、單位利潤比較；實驗數據顯示連續模具比複合模具成本為高，日生產量連續模具產量比複合模具產較高，單位利潤比較上連續模具單位利潤比複合模具低，而連續模具適用於生產體積小之成型件，生產效率高、生產速度快。複合模具成本雖然較連續模具低，但其主要適用於生產體積大、單價較高之成型件。以小體積成型件而言，訂單數量通常很大。

This thesis design progressive dies for stamping molding workpieces with ground terminal. Taking the cost and the process into account, design the plates, punches, dies and processing methods. Then reckon the cost of materials, processing methods and hardware. Testing dies and adjusting the machine after the dies are finished. At last, study the problems of dies repair during punching. For example, punch crack, punch passivating, jam and unusual burr. Progressive dies stamp the stamping molding workpieces with ground terminal. And compare progressive dies with composite dies. Provided that there is 300 thousands yield, one worker, 8 hours a day, and 5 days a week, find the difference of dies cost, daily yield and unit profit between progressive dies and composite dies. The experimental data shows that dies cost and daily yield of progressive dies are higher than composite dies but the unit profit is lower. Progressive dies with high producing efficiency and speed are good at producing little workpieces. Composite dies are cheaper and used to produce large workpieces and high unit profit workpieces. The little workpieces are always with a large number of order.
