河南科技学院 2011届本科毕业论文（设计） 论文题目：基于Proe的谐振窗复合冲压模具制造与设计 学生姓名： 所在院系：机电学院 所学专业：机械设计制造及其自动化 导师姓名： 摘 要 冲压复合模具结构紧凑，一套模具能完成若干工序。本文主要介绍了基于冲孔、落料两个工序的复合模具，本模具是依据谐振窗的小工件的大批生产设计的，分析了谐振窗的冲压工艺和冲压工序的组成，对载体和排样设计方案作了分析和设计，分析了产品外形合理的接边工艺，确定了条料的送进与导料方式及定距结构形式，并对模具的主要部件设计作了详细地说明。同时也包含了冲裁力计算，定距方法，冲裁间隙选择，压力中心计算的设计要点。对模具的主要工作部位进行了详细的计算和设计，合理选择了400KN开式可倾压力机。 关键词：谐振窗，冲压复合模，冲压工艺，冲裁间隙，压力中心 Abstract Stamping compound mould structure compact ,a set of mould can accomplish several processes . This paper mainly introduces the two process of punching and dropping material based on the composite mold. This mold is based on the window of small workpiece resonant mass production design . Analysis of the resonant window stamping process and the composition of punching process .And the technological process for stamping the part is analyzed and the layout designs are analyzed and designed, rational joint-edge process of products outline, decided the guiding of the bar stock and the form of the fixed distance , describes the key die parts in detail. At the same time, includes the main design point of stamping force calculation , fixed distance method, the selection of stamping clearance, compress force center an so on . Reasonable chose 400KN open-cycle tilt press. Keywords: Resonant window ,Stamping compound mould, Stamping process, Cutting clearance, Pressure center  目 录 1 绪论………………………………………………………………………………1 1.1 概述…………………………………………………………………...........1 1.2 冲压的特点及应用………………………………………………………...2 1.3 模具的特点及分类………………………………………………………...2 1.4 模具CAD/CAE/CAM……………………………………………………...3 1.5 Pro/E在模具CAD/CAE/CAM………………………………..…………...4 1.6 钣金模架库模块…………………………………………………………...5 2 对零件的综合分析………………………………………………………………5 2.1 工艺分析及模具结构类型………………………………………………...6 2.1.1 工艺分析…………………………………………………………..6 2.1.2 复合模的特点及选用……………………………………………..7 2.2 排样方案…………………………………………………………………...8 2.3 材料利用率………………………………………………………………...9 2.4 压力中心及冲压力的计算………………………………………………...10 2.4.1 冲孔冲压力计算…………………………
