搭扣冲压工艺及其模具设计
摘 要:本文设计的是搭扣的冲压工艺分析和模具的具体结构设计。通过对搭扣的工艺性分析,选择符合于给
定条件的最优工艺方案,如:选择基本工序,确定其顺序,工序数目及工序组合形式。然后以此为基础,设计
出冲压模具主要零件的结构。结合实际,进行合理、正确的规划。在设计中,介绍了零件的排样图、定位设计
、冲裁力的计算和压力中心的计算。在详细分析搭扣零件工艺的基础上,设计出了级进模这套模具,并详细介
绍了级进模模具的结构和主要零件。

Design of Hasp Stamping Craft and Mold
Abstract: The design focus on both the analysis of Pessing technics of the hasp and the
particular configuration design of die. It is based on the technical analysis of the branch nog
on the Pendulum to choose a best craft procedure.For instance, basic procedure’s choosing ,basic
procedure’s sequence confirmatio,the amount of the working procedure and the format of the
procedure combination.After the steps upward, then it start the design of the main part of the
pressing die.Relate with the practice to make the reasonable and correct layout.It’s presented
on the design regarding the part sampleing makeup ,orientation design,calculation of puch forch
and center pressing.Again,the design of the progressive die is based on the particular analysis
of the part craft of the hasp.The main parts and configurations of the design have described on
the paper in detail. Key words: stamping ; mold design ; blanking ; hasp
