电动车遮雨外壳冲压模设计 1 摘 要 本设计进行了落料、冲孔连续模的设计。文中简要概述了冲压模具目前的发展状 况和趋势。对产品进行了详细工艺分析和工艺方案的确定。按照冲压模具设计的一般 步骤，计算并设计了本套模具上的主要零部件，如：凸模、凹模、凸模固定板、垫板、 凹模固定板、卸料板、导尺、挡料销、导正销等。模架采用标准模架，选用了合适的 冲压设备。设计中对工作零件和压力机规格均进行了必要的校核计算。此外，本模具 采用始用挡料销和钩形挡料销挡料。模具的冲孔和落料凸模分别用不同的固定板固定， 便于调整间隙；冲孔凹模和落料凹模则采用整体固定板固定。 关键词 ：冲压模具；标准模架；冲压设备；校核；冲孔；落料 ABSTRACT This design contains blanking, punching mould and continuous mode design. This paper summarizes the stamping mould development status and trends .We perform an detailed process analysis and make sure the scheme process. According to the general procedure of stamping mould design, it calculates and designs the main component of this mould, such as the punch, hollowing block, punch plate, pad , retainer plate , stripper plate, lead-ruler ,stop pin , pilot pin and so on. Formwork uses standard module and chooses a suitable .This design conducts necessary check and calculation for the press equipment and working elements. In addition, this mould uses stop pin and stop pin of hook type to block material. Punching and blanking punch of the mould are respectively fixed different fixed plates, which are convenient for adjust clearance. Punching and .blanking hollowing block use overall fixed plate to fix. Key words: stamping tool; standard module; press equipment; check; punching blanking 2 目 录 1、 引言4 2、 零件简介10 3、 冲压件工艺分析11 3.1 冲压工艺介绍11 3.2 冲压成型理论11 3.3 冲压的工艺种类12 3.4 零件冲压工艺分析13 4、工艺方案及模具结构类型14 5、冲孔落料模模具设计计算15 5.1 排样15 5.1.1 确定搭边值15 5.1.2 条料宽度和步距15 5.2 计算总压力15 5.3 确定压力中心15 5.4 冲模刃口尺寸计算及公差的计算15 5.5 工件零件结构尺寸16 5.6 其定模具零件结 17
