毕业设计（论文）：冲压倒装复合模的结构设计.doc

摘 要 冲裁工艺在工业生产中应用广泛，冲压模具设计与制造技术是一项技术性和经验性都很强的工作。本次毕业设计根据毕业设计任务书提供的零件图纸要求,用Auto CAD进行设计分析。根据分析结果选择合理的冲压工艺和合理的模具结构，在此基础上优化零件结构和选择合适的零件材料。经过查阅资料，首先要对零件进行工艺分析，经过工艺分析和对比，采用冲孔落料工序，通过冲裁力、顶件力、卸料力等计算，确定压力机的型号。再分析对冲压件加工所需的模具类型，选择所需设计的模具类型。 本文首先叙述了冲压模具的发展状况，模具在现代工业中的作用，和在整个国民经济中的地位。说明了冲压模具的重要性与本次设计的意义，接着是简单说明了模具设计的基本概念和模具设计的一般步骤、模具的分类、模具零件的分类、模具的结构形式、冲压的基本概念、冲压工艺基础理论、塑性力学基础理论。然后对冲压件进行工艺分析，完成了工艺方案的确定，对零件排样图的设计，完成了材料利用率的计算。再进行冲裁工艺力的计算和冲裁模工作部分的设计计算，为选择冲压设备提供依据。其次对主要零部件的设计和标准件的选择，为本次模具零件图的绘制和模具的成形提供依据，以及为装配图各尺寸提供依据。通过前面的设计方案画出模具各零件图和装配图。 本次设计阐述了冲压倒装复合模的结构设计及工作过程。本模具性能可靠，运行平稳，提高了产品质量和生产效率，降低劳动强度和生产成本。 关键字：冲裁；落料冲孔；倒装复合模；模具结构 ABSTRACT Application is broad according to cutting handicraft in the commercial run. That dies designs and makes a technology is one item technicality and all very strong job of experience. Originally, time, This graduation design based on the graduation design programme .Make use of the computer CAD software to assist design。Choose rational stamping handicraft and rational mould structure according to analysing result. The basis fixes the part material optimizing part structure and choosing rightly here. Look up a data through.. First be going to carry out industrial analysis on the part , Industrial analysis and contrast pass. Adopt punched hole blank working procedure. Passing according to cutting a force , being equivalent to a force in being unloaded piece strenuously, and so on secretly schemes against, ascertain the press machine type. Again analysis stamps the type processing the required mould piece face to face. Choose the required mould type. Situation the main body of the book has been narrated first stamping development of mould. Mould effect in modern industry and position in drawing in entire national economy. Have explained the significance that dies significance and common process. The step having explained the design for die and mould basic concept and the design for die and mould sort simplely follow, the mould classifi
