1、 1 毕业设计 题目 密封盖冲压模具设计 学院 机电工程学院 专 业 班 级 机械 102 学 生 姓 名 指 导 教 师 成绩 年 月 日 2 摘摘 要要 近年来，随着我国化工机械工业迅速发展，密封盖零件的数量日益增大，文中对 密封盖零件的冲压工艺进行分析，改用冲孔翻边落料连续模生产，可明显提高制 件质量及生产率，从而降低成本。 本设计说明书主要介绍密封盖级进模的设计过程，包括密封盖毛坯的排样图、方 案分析及模具的选择、冲压力等工艺计算等。 通过对密封盖的工艺分析，采用先冲预孔，再进行翻边。翻边时材料流动的特点 是预孔周围的材料沿圆周方向伸长，材料变薄，径向材料几乎没有变化，排样时采用 正常
2、的搭边值即可，这样可明显节省材料。设计密封盖冲孔翻边落料级进模结构， 改善过去的单工序的简单模生产。 关键词关键词：密封盖；翻边工艺；排样设计；级进模具 3 ABSTRACT In recent years，with the rapid development of industry of chemical machinery, the number of sealing cover parts is increasing. In this paper, we have an analysis of the sealing cover parts stamping process, and s
3、witch to the progressive die of punching - flanging - blanking to product the parts.It can significantly improve the product quality and productivity and reduce the costs. This paper mainly introduces the sealing cover of progressive die design process, including a sealing cover blank layout, progra
4、m analysis and mold selection, punching pressure process calculation.,and so on . Based on the analysis of the process of sealing cover,first punch the pre-holes and then flang it. The characteristics of the material flow in the flange is that the material around the pre-holes elongats along the cir
5、cumferential direction,the material changes to thin, radial material has almost no change. When nesting,we can take the normal take-boundary value,and it can obviously save material. Design the structure of the modulus of continuity of punching - flanging - blanking of sealing cover. Improve the simple mode of production of the past single procedure. Key words: Sealing cover, Flanging process, Strip layout, Progressive die 4 目 录 摘 要 2 ABSTRACT
