1摘要 冷冲压也称板料冲压，是塑性加工的一种基本方法，一般与金属板料为原料，利用压力机上的模具往复运动，在常温下对金属施加压力，使板料产生塑性变形欲达到预定的形状尺寸。本文对一个简单的冲压工艺进行分析，并设计了级进模及主要零部件，在这个课题设计中详细介绍了冲裁剪从排样设计到模具结构设计，再到装配的整个过程，通过这个课程设计让我知道了什么是冷冲压。本设计根据导师给的说明要求及零件图，对零件进行工艺分析，确定其公差等级，再进行冲裁方案确定为落料、冲孔工序，使用级进模具，既满足大批量生产的要求，也增大了利益。有冲孔，落料工序，故先要进行工艺计算，确定其毛坯尺寸，再进行排样方案的确定，计算材料的利用率，再计算主要工作零件的工作部分尺寸计算，接着对其主要工作零件的外形尺寸的计算，接着计算冲压力和压力中心。接着就是其他零件的选用及计算，如紧固零件、导料，模柄模架等。最后根据计算结果选用适合的压力机的型号，最后画好零件图及装配图。关键词：关键词：冲压件; ; 排样设计； 模具结构； 装配2Abstract Cold pressing ,alsoknown as sheet metal,is a baiic method of plastic processing,generally sheet metal asraw material,using press the mold for reciprocating motion,at room temperature on the metal piate to exert pressure on the sheet to produce plastic deformation to achieve the desired shape and size. In this paper,a simple stamping of the stamping process is analyzed and designed punching,blanking dies and the main components.Through this simple example,let us know what is the cold stamping process.Structure; assembly The graduation design for sleeve drawing parts stamping mould design, according to the requirements and mentor to that drawing, the analysis of the technology of parts, determine the tolerance level, and then to cutting plan for blanking, deep drawing, punching process, use compound mould, which can meet the requirement of mass production, and increase the interest. A deep drawing process so first process calculation, determine the blank dimensions, and then to the layout for the determination, calculate material utilization ratio. Then rushed pressure calculation, preliminary of the main parts working part size calculation, then the overall size of the main parts of the calculation, and then choose the fixed way. Then there are the other parts of the selection and calculation, such as elastic components, fastening parts, guide materials, etc. According to the calculation results, we choose the suitable of formwork, make sure the machine model and die handle, finally draw good parts drawing and assembly drawing, the design is over.KeyKey words:words: size calculation; dropping material; deep drawing; punching 3目录目录摘要.IABSTRACTABSTRACT.II目录目录.III绪论绪论.V冲压模的特点和应用.V2 冲压的现状和发展趋势.V3 冲压基本原理的研究.V设计课题：设计课题：.11. 工艺分析.22 冲压工艺方案的确定.23. 工艺尺寸的计算.33.1 排样的设计.33.2 材料利用率的计算.43.3 排样的选择 .53.4冲裁力与压力中心的计算.53.5冲裁力压力中心的确定.63.6 刃口尺寸的计算 .63.6.1 凸凹模加工方法的确定.63.6.2 加工工序.73.6.3 工件零件各类尺寸.7尺寸具体计算.83.7 凹模外形尺寸计算 .94. 工艺零件的设计.104.1 凹模的设计 .104.1.1 凹模形状及孔位的设计.1044.1.2 凹模类型的选择.104.1.3 凹模尺寸的计算.114.1.4 凹模的固定.124.2 凸模的设计.124.2.1 凸模类型的选择.124.2.2 凸模的计算.134.2.3凸模强度的校核.144.3 卸料版的设计.144.4 导料板的设计 .154.5 挡料销的选用 .164.6 导正销的选用 .165 结构零件的设计 .175.1 凸模固定板的设计 .175.2 垫板的设计 .1
