落料冲孔复合冲压模具【摘要】：冲压所使用的模具称为冲压模具，简称冲模。冲模是将材料（金属或非金属）批量加工成所需冲件的专用工具。冲模在冲压中至关重要，没有符合要求的冲模，批量冲压生产就难以进行；没有先进的冲模，先进的冲压工艺就无法实现。冲压工艺与模具、冲压设备和冲压材料构成冲压加工的三要素，只有它们相互结合才能得出冲压件。本文是对垫片落料冲孔进行复合模具设计。关键词：复合模具落料冲孔Abstract:stampingdiesusedinstampingdieiscalledforshortdies.Dieisthematerial(metalornon-metallic)intothebatchprocessingofthespecialtoolsrequiredforstamping.Iscrucialinstampingdie,thediedoesnotmeettherequirements,batchstampingproductionwillbedifficulttoplace;notbeanadvanceddie,advancedstampingprocesscannotbeachieved.Stampingprocessanddie,stampingequipmentandstampingmaterials,thethreeelementsconstitutethestampingprocess,onlythattheybecombinedinordertoobtainstampings.Thisarticleisagasketpunchtocompositeblankingdiedesign.Keywords:compositeblankingpunchingdie目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc257658931"前言PAGEREF_Toc257658931\h3HYPERLINK\l"_Toc257658932"1冲压的概念、特点及应用PAGEREF_Toc257658932\h3HYPERLINK\l"_Toc257658933"1.1冲压的基本工序及模具PAGEREF_Toc257658933\h4HYPERLINK\l"_Toc257658934"1.2冲压技术的现状及发展方向PAGEREF_Toc257658934\h4HYPERLINK\l"_Toc257658935"2.零件的工艺性分析.PAGEREF_Toc257658935\h10HYPERLINK\l"_Toc257658936"2.1零件的工艺性分析PAGEREF_Toc257658936\h10HYPERLINK\l"_Toc257658937"2.2冲裁件的精度与粗糙度PAGEREF_Toc257658937\h11HYPERLINK\l"_Toc257658938"2.3冲裁件的材料PAGEREF_Toc257658938\h11HYPERLINK\l"_Toc257658939"2.4确定工艺方案.PAGEREF_Toc257658939\h11HYPERLINK\l"_Toc257658940"3.冲压模具总体结构设计PAGEREF_Toc257658940\h11HYPERLINK\l"_Toc257658941"3.1模具类型PAGEREF_Toc257658941\h11HYPERLINK\l"_Toc257658942"3.2操作与定位方式PAGEREF_Toc257658942\h11HYPERLINK\l"_Toc257658943"3.3卸料与出件方式PAGEREF_Toc257658943\h12HYPERLINK\l"_Toc257658944"3.4模架类型及精度PAGEREF_Toc257658944\h12HYPERLINK\l"_Toc257658945"4.冲压模具工艺与设计计算PAGEREF_Toc257658945\h12HYPERLINK\l"_Toc257658946"4.1排样设计与计算PAGEREF_Toc257658946\h12HYPERLINK\l"_Toc257658947"4.2设计冲压力与压力中心,初选压力机PAGEREF_Toc257658947\h13HYPERLINK\l"_Toc257658948"5.模具的总张图与零件图PAGEREF_Toc257658948\h17HYPERLINK\l"_Toc25765894
