摘  要

介紹了電機油箱外殼的模具設計過程。通過對零件進行工藝分析、制定了合理的工藝方案。然后根據(jù)工藝方案進行了毛坯尺寸計算、排樣、沖壓工藝力的計算、彈性元件的選用、凸凹模工作部分尺寸和公差的確定。進而設計出一套模具，包括落料拉深模、脹形模、沖孔翻邊模等
關鍵字：沖壓、沖孔、落料、拉深、復合模；

Introduced the electric tank shell mold design process. Parts through the process of analysis, the development of a reasonable process plans. Technology programs based on the size of the rough, the layout, the calculation of punching technology, flexible components to choose from, the work of convex and concave mold part to determine dimensions and tolerances. To design a mold, including blanking Drawing Die, Die bulging, punching flanging die, such as
