保持架沖壓模具設計
摘要：本設計題目為保持架前半部分設計，落料拉深沖孔復合模設計，體現(xiàn)了拉深件沖壓零件的設計要求、內容及方向，有一定的設計意義。通過對該零件的模具設計，進一步加強了我的沖壓模具設計的基礎知識，為設計更復雜的沖壓件做好了鋪墊和吸取了更深刻的經驗
本設計運用沖壓成型工藝及模具設計的基礎知識，首先分析了該零件的材料和各方面的要求和拉深原理分析、拉深工藝方案的選擇、沖孔和落料工藝方案的選擇、模具結構設計計算為沖壓工藝做好了準備；查資料材料的各力學性能，便于選取壓力機，計算了各主要工作零件的尺寸，查資料選取的各零件的選用和安裝方法。
本制件與其他拉深件不同，工序復雜，在這我做的是落料、拉深、沖預孔工序。沖壓該零件時，普遍采用落料、拉深、沖孔、三道工序，生產效率低，成本也高。為此設計了該零件的落料、拉深、沖孔復合模具，是原三道工序合為一，大大提高了生產效率。
關鍵詞：模具 拉深 沖孔
Stamping dies design
Abstract: This design topic is frame before half part design, design of compound die of blanking drawing piercing, reflects the design of deep drawing stamping parts requirements, content and direction, the design of a certain significance. Through the die design of the parts, to further strengthen the basic knowledge of stamping die design I, paving the way and draw a more profound experience of stamping design more complex parts.
This design using the basic knowledge of stamping forming process and die design, analyses, the parts of the materials and the requirements and the drawing principle drawing scheme selection, punching and blanking process scheme selection, die structure design calculation ready for stamping process; the mechanical properties to check information materials, to select the press, the main working parts size calculation, selection of various parts of the check data selection and installation method.
This product is different, and other drawing of complex processes, blanking, drawing, punching hole process in this I do is. The parts stamping, blanking, drawing, punching, three processes widely used, the production efficiency is low, the cost is high. For the design of the blanking, drawing, punching compound die of the part, is the original three processes are combined into one, greatly improving the efficiency of production.
