This mold is not primarily designed to complex design, but mainly on a systematic study of mold design knowledge and practice, in order to achieve the purpose of master the basic skills of stamping mold design.First of all, do a thorough analysis for the parts, which include the using of the material, the requirement of accuracy and the requirement of working procedure and costs and so on. For declining low cost, proceeded the reasonable design to the row kind method. Secondly, do processing design for the whole parts and the purpose by craft designing and order of the working procedure and by the choice of punching machine. Thirdly, consider the calculation of size of the mould cutting edge in order to meet the need of accuracy. Because the cutting edge is the main working part of the punching processing, the accurate cutting edge guarantees the accurate parts. So you needed to tolerance do accurate calculation.Finally, according to the calculated the size of mold cutting edge design the corresponding punch and mold, and find information on selection criteria for cold stamping parts, meet the standards, put the punch and mold with the other components to the overall assembly. In determining the specific mold closed height, select the appropriate press in the debug and test validation washed after processing, to meet compliance standards, the final completion of the processing chain plate.Keywords：composite modulus, stamping process, mold design , punching blanking目 錄摘要1Abstract2目錄3第1章 緒論51.1 我國(guó)模具技術(shù)的現(xiàn)狀及發(fā)展趨勢(shì)51.2 沖壓模的現(xiàn)狀與發(fā)展趨勢(shì)61.3 外國(guó)模具工業(yè)的發(fā)展?fàn)顩r71.4 課題研究的內(nèi)容8第2章 工藝性分析92.1 零件的分析92.1.1 沖壓件的尺寸精度92.1.2 生產(chǎn)批量92.2 工藝方案分析102.3 模具間隙的確定112.4 設(shè)備的選擇12第3章 排樣設(shè)計(jì)153.1 搭邊173.2 送料進(jìn)距173.3 條料寬度173.4 本章小結(jié)18第4章 模具總體設(shè)計(jì)194.1 模具類型的選擇194.2 定位方式的選擇194.3 卸料出件方式的選擇20第5章 模具的裝配和沖裁模具的試沖215.1 模具的裝配215.2 沖裁模具的試沖225.3 裝配圖25結(jié)論與展望26致謝27參考文獻(xiàn)28
