Z形件板冲压工艺及落料冲孔、弯曲模具设计 摘要 进入20世纪90年代以来，各式各样的五金件成为了主流。由于在生活中许多都要用到五金件，因此，五金冲压模具将不断发展，在近几十年里会有突飞猛进的成果。通过翻阅这些参考资料和文献，深入了解了当代的模具先进制造技术和冲压成型技术。查找整理资料后，对一些模具设计实例有了解与学习，进一步学习了冲压模具设计的方法，并能对模具设计的成本价格做出估算，从而对模具设计有了方向性的指导。 通过对深入学习，对此零部件模具设计时的设计方式有了雏形。先分析零件的冲压工艺；确定模具的总体结构；结合零件的冲压工艺及模具的总体结构设计排样图；根据排样图，计算利用率、冲载力、压力、选用设备及刃口的尺寸。根据资料再用AutoCAD，对模具进行设计，然后绘出装配图和零件图进行标注，并编制零件的加工工艺卡，使理论和生产实际知识综合运用，从而培养和提高了我独立工作的能力。 关键词：冲压模具，冲孔，切边，折弯 Abstract Si
