连接板冲压成形工艺及模具设计 摘要 压力，使其产生分离或塑性变形，从而获得所需零件的一种压力加工方法。弯曲是将板料、棒料、管材和型材弯曲成一定角度和形状的冲压成形工序。本文主要研究工作：利用连接板特征之间的关系建立级进模排样设计模型，引入冲压冲压是利用安装在冲压设备（主要是压力机）上的模具对材料施加排样设计原则；进一步将连接板的形状特征应用于模具结构设计中，建立模具模型，进行模具工艺设计和结构设计，从而确定总体的模具形式；模具投入制造后，可能在制造和生产调试过程中表现出设计的不足和错误，通过总结概括这些问题，可以进行修正工艺设计和模具结构设计，或增加新的工艺规则，为以后的模具设计提供宝贵的经验。 关键词：冲压连接板模具 Co
