1、东风汽车公司高级技工学校（技师学院）东风高级技工学校（技师学院）毕业设计（论文）题目变速箱冷油器托架弯曲模具设计指导教师院（系、部）机制教研室专业班级模具设计与制造JS816学号39姓名日期2012年2月27日摘要65东风汽车公司高级技工学校（技师学院）我做的课题是汽车上的变速箱冷油器托架弯曲模具设计。此产品零件需要冲孔落料、翻边、弯曲三道工序完成。本文主要是根据弯曲工序，设计一套弯曲模具，完成零件第三道序的加工生产。设计内容主要包括零件展开尺寸、排样和材料利用率以及弯曲力的计算；压力中心的计算和压力机的选择；模具结构的设计；模具主要零件的设计和模具装配技术要求等等。在设计过程中除了有

2、说明书外，还包括模具装配图，非标准零件的零件图。本文介绍的模具结构简单，安全可靠，满足设计的要求。这次的毕业设计锻炼了我的个人能力，使我了解了模具的设计流程，获益匪浅。关键字：冲压、弯曲、模具结构65东风汽车公司高级技工学校（技师学院）AbstractTheissueisIdoautomotivetransmissionoilcoolerbracketbendingmolddesign.Processanalysisrequirespunchingblanking,flanging,bendingthreeprocessestocompletethepartingthispaper,t
