洛阳理工学院毕业设计（论文）平垫圈冲裁复合模模具设计摘 要本次设计了一套冲孔、落料的倒装复合模具。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、卸料力等的计算分析确定压力机的型号；其次分析适用于冲压件加工的模具类型，选择所需设计的模具；最后得出模具的类型后，将模具的各工作零部件设计过程表达出来。本文的第一部分，主要叙述了冲压模具的发展状况，说明了冲压模具的重要性与本次设计的背景，接着是对冲压件进行工艺分析，确定工艺方案；第二部分，对零件排样图的设计，完成了有关工件各个力的计算，对选择冲压设备提供依据。最后是对主要零部件的设计计算，为本次设计模具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装配图和各零件图。关键词：倒装复合模具、厚料冲裁、冲裁间隙洛阳理工学院毕业设计（论文）IFLAT GASKET COMPOSITE DIE CUTTING MOULD DESIGNABSTRACTThis design is a set of flip and compound mold about punching and blanking.By consulting materials， we should analyse the parts technics firstly.Through analysis and comparison，I decide to use the punching and blanking process.Then by means of the analysis and calculation that is about blanking force ejecting force stripping force etc.we can ensure the press machines model number.Secondly，I analyse the molds type using in stampings process and choose which I need.In the end，after this working I will convey the designs process of the dies all working parts.The first part of the article,mainly describes the development of stamping die and explains the importance of stamping die as well as the background of the design. Then is the technology analysis of the stamping parts and determine a technological plan.The second part illustrate the parts layout.Then I complete all forces calculation about the workpieces.This can provides selections for choosing stamping equipment.In the end，I design and calculate the main partss data that provides selections for the molds design and shaping along with ascertaining all sizes of assembly drawing. Through the formers design I draw dies assembly drawing and parts drawing.KEY WORDS: Flip composite mold Thick material blanking blanking clearance 洛阳理工学院毕业设计（论文）II目 录前 言.1第 1 章 工艺分析及其方案确定.21.1 零件的工艺分析.21.2 工艺方案的确定.21.3 排样的确定.31.4 条料宽度的计算.5第 2 章 冲压设备的选用与相关计算.62.1 冲裁方式的确定与冲压力的计算.62.1.1 冲压方式的确定.62.1.2 冲压力的计算.62.2 冲压设备的选用.82.3 压力中心的确定.82.4 凸、凹模的有关计算.92.4.1 凸、凹模间隙值的确定.92.4.2 凸、凹模的刃口尺寸的计算和公差的确定.9第 3 章 主要零部件的尺寸设计与计算.133.1 凸模的设计.133.1.1 凸模设计的原则.133.1.2 凸模的类型选用及校核.143.2 凹模的设计.163.2.1 凹模洞口形状的选择.163.2.2 凹模外形尺寸的确定.173.3 凸凹模的设计.183.4 固定零件的选用.193.5 弹压卸料装置的设计.203.5.1 卸料板 .203.5.2 橡胶 .213.6 定位零件.23洛阳理工学院毕业设计（论文）III3.6.1 导料销类型的设计.233.6.2 挡料销类型的设计与确定.243.7 导向零件.253.8 打杆和推（顶）杆.263.9 推件装置.273.10 模架的选用.283.10.1 模具的闭合高度的计算.283.10.2 冲模模架 .283.11 零件技术要求.30第 4 章 模具的调试.
