在激烈的市场竞争中,产品投入市场的快慢往往是成败的关键。模具是高质量、高效率的生产工具,其开发周期占整个产品开发周期很大的比重,能否缩短开发周期就成为了产品成败的关键,而在工业工程应用日益广泛的今天,缩短模具开发的周期就成为一种必然趋势。本次毕业设计的任务是设计一套机架框冷冲模具。一方面，通过利用各种国家标准和力学分析设计出一套实用性强的模具；另一方面，通过利用Pro/E、CAD等电脑软件技术来缩短产品开发周期。这样可以加快产品整个流程进度，占领消费者心智市场，为以后同产品之间的价格竞争积累资源。关键词：机架框冷冲模具落料模冲孔模弯曲模凸模凹模落料力冲孔力卸料力弯曲力顶件力AbstractInthefiercemarketcompetition,productspeedtomarketisoftenthekeytosuccess.Moldishighquality,highefficiencyofproduction,Thedevelopmentcycletakeslargeshareofthewholeproductdevelopmentcycle，shortentheproductdevelopmentcycleornothasbecomethekeytosuccess，butusedwidelyinindustrialengineeringtoday,toshortenthedevelopmentcycleofmoldhasbecomeaninevitabletrend.Thecontentofthisgraduationprojectistodesignasetofthecolddietomaketherackframe.Ontheonehand,throughtheuseofnationalstandardsandmechanicalanalysistodesignapracticalmold;Ontheotherhand,throughtheuseofCAD,Pro/Eandothercomputersoftwaretechnologytoshortentheproductdevelopmentcycle.Thiscanacceleratetheprogressoftheentireprocess,ocupiedtheconsumermindmarket,andaccumulateresourcesforthesubsequentpricecompetitionbetweenthesameproducts.Keywords:DieforRackframeBlankingdiePiercingdieBendingdieProtrudingdieConcavedieBlankingforcePunchingforceUnloadingforceBendingforceToppiecesforce目录TOC\o"1-3"\h\zHYPERLINK\l"_Toc295651516"HYPERLINK\l"_Toc295651517"第一章前言PAGEREF_Toc295651517\h1HYPERLINK\l"_Toc295651518"选题的目的PAGEREF_Toc295651518\h1HYPERLINK\l"_Toc295651519"题目的意义PAGEREF_Toc295651519\h1HYPERLINK\l"_Toc295651520"第二章冲压的基本知识PAGEREF_Toc295651520\h2HYPERLINK\l"_Toc295651521"冲压的基本工序PAGEREF_Toc295651521\h2HYPERLINK\l"_Toc295651522"冲压加工的特点及应用PAGEREF_Toc295651522\h4HYPERLINK\l"_Toc295651523"冲压加工的特点PAGEREF_Toc295651523\h4HYPERLINK\l"_Toc295651524"2.2.2冲压加工的应用PAGEREF_Toc295651524\h4HYPERLINK\l"_Toc295651525"冲压模具PAGEREF_Toc295651525\h5HYPERLINK\l"_Toc295651526"2.3.1冲模的要求PAGEREF_Toc295651526\h5HYPERLINK\l"_Toc295651527"2.3.2冲模的种类PAGEREF_Toc295651527\h5HYPERLINK\l"_Toc
