1、手柄冲孔、落料级进模的设计与制造[摘要]本文介绍的是一副手柄冲孔、落料级进模的设计与制造，其内容包括：零件的工艺分析、工艺方案的确定、冲压工艺的相关计算及设计、模具类型及结构的确定、模具材料的选择、主要零部件的设计、主要零部件的制造及模具的装配。此模具采用人工送料，送料时板料依靠左右两导料板进行导向。因工件具有一头大一头小的特点，所以采用双向排样，隔位冲裁。首个工件冲裁时的定位依靠始用挡料装置来确定，之后用固定挡料销进行定位。冲压过程中工件还须通过装在凸模上的导正销来进一步精确定位，使冲出的制件达到图样要求。模具采用弹性卸料方式，这

2、样在冲压时卸料板可压紧条料，使冲出的工件表面平整，毛刺少或无毛刺。工件和废料则直接从压力机工作台孔中漏下，不需对模具进行清理，节省了时间，提高了生产率，同时操作安全、方便。[关键词]手柄冲孔、落料　　级进模　设计、加工装配目录一、前言··································································································135二、零件的工艺分析··········································
