南京工程学院毕业设计说明书论文作者高小敏学号088811202049学院(系、部)机械与电子工程系专业数控加工与模具设计题目固定夹的复合模设计指导者何玉林讲师评阅者2013年4月南京南京工程学院毕业设计说明书(论文)I毕业设计说明书(论文)中文摘要固定夹的复合模设计本论文应用本专业所学课程的理论和生产实际知识进行一次冷冲压模具设计工作的实际训练从而培养和提高了我的独立工作能力。本设计通过对固定夹的复合模设计的工艺性分析,确定了正确的工艺方案。从而对模具设计方案,以及冲压设备作出了分析与选择。通过分析决定采用复合模形式,然后参考其他模具结构以及查手册和计算设计。当所有的参数计算完后,对模具的装配方案,对主要零件的设计和装配要求技术要求都进行了分析。在设计过程中除了设计说明书外,还包括模具的装配图,非标准零件的零件图,工件的加工工艺卡片,工艺规程卡片,非标准零件的加工工艺过程卡片。关键词冷冲压复合模设计南京工程学院毕业设计说明书(论文)II毕业设计说明书(论文)外文摘要TitleDesignofcompounddieforfixingclampAbstractTheapplicationoftheprofessionalpracticaltrainingcoursestheoryandpracticalknowledgeofacoldstampingdiedesignworktodevelopandimprovemyabilitytoworkindependently.Thisdesignthroughtheanalysisprocessofthecompounddiedesignoftheretainingclip,correcttechnologyschemewasdetermined.Thusthemolddesign,andstampingequipmenthasmadetheanalysisandchoice.Throughtheanalysisofdecisionwithcompounddieform,thenthereferenceothermoldstructureandmanualsearchanddesigncalculation.Whenalloftheparametercalculationisfinished,themoldassemblyprogram,themainpartsofthedesignandassemblyrequirementsofthetechnicalrequirementsareanalyzed.Inthedesignprocess,inadditiontothedesignspecifications,butalsoincludingthemoldassemblydrawing,nonstandardpartsdrawings,theworkpiececardprocessingtechnology,processcards,processcardsnonstandardparts.KeywordsColdstampingcompounddieDesign南京工程学院毕业设计说明书(论文)III目录毕业设计说明书(论文)中文摘要...................................................................................I毕业设计说明书(论文)外文摘要..................................................................................II目录................................................................................................................................III前言..................................................................................................................................1第一章绪论..............................................................................................................21.1冲压模具的现状..................................................................................................21.1.1模具工业现状............................................................................................21.1.2模具工业技术结构现状............................................................................31.1.3模具工业配套材料,标准间结构现状....................................................41.1.4模具工业产业组织结构现状....................................................................51.2模具的发展趋势..................................................................................................51.2.1模具CAD/CAE/CAM的发展方向..........................................................51.2.2模具检测、加工设备向精密、高效和多功能方向发展........................61.2.3模具工业新工艺、新理念和新模式逐步得到了认同............................71.3冷冲压模具分类与特点......................................................................................7第二章零件的工艺分析和工艺方案的确定................................................................92.1冲压弯曲件的工艺分析......................................................................................92.2确定工艺方案及模具的结构形式....................................................................102.3零件的工艺分析................................................................................................102.3.1计算毛坯尺寸..........................................................................................102.4排样、计算条料宽度及步距的确定................................................................132.4.1搭边值的确定..........................................................................................132.4.2条料宽度的确定......................................................................................142.4.3导板间间距的确定..................................................................................152.4.4排样..........................................................................................................152.4.5材料利用率的计算..............................................................................16第三章冲裁力的计算..................................................................................................183.1计算冲裁力的公式............................................................................................183.2总冲裁力、卸料力、推料力、顶件力、弯曲力和总冲压力........................183.2.1总冲裁力..............................................................................................183.2.2卸料力Fx的计算....................................................................................193.2.3推料力Ft的计算.....................................................................................203.2.4顶件力Fd的计算....................................................................................203.2.5弯曲力FC的计算...................................................................................203.2.6总的冲压力的计算..................................................................................21第四章模具压力中心与计算......................................................................................22第五章冲裁模间隙的确定..........................................................................................23第六章刃口尺寸的计算........................................................
