1、 【摘要】 ：本课题是订书机连接板的级进模具。通过工艺分析，订书机连接板级进模模具包含了冲 裁、弯曲、压筋三步工艺步骤，其中冲裁拥有四个步骤，压筋一个工步、弯曲两个工步。订书机连 接板级进模采用侧刃定距的定位方式， 能够准确对条料进行定距； 送卸料方式是通过人工送料和弹 性卸料来实现的。由于级进模模具的定位精度要求较高，因而用了四导柱的定位方式。模具的主体 采用了整体结构， 凸凹通过配合加工来满足凸凹模之间的精度要求。 模具的凸模定位方式采用了台 阶式结构。 该模具的设计过程： 先通过工艺分析确定了工件的排样图 （其中包含： 工艺步骤的划分， 条料的定距方式，凸凹模的形状等）,通过排样图确定凸

2、凹模的尺寸，通过 AUTOCAD 绘制出凸凹模 的工程图，再运用 UG 绘制出模具各部分的三维模型，按照要求用 UG 对模具各零部件进行装配。 【关键词】 ：级进模;订书机;精度;定位 Abstract: The topic is about progressive die of Stapler gusset. Through analysis of the technology, we can draw the conclusion that Progressive Die of stapler gusset includes fore-step processing stepsblanki

Progressive die of stapler adopting the targeted approach can accurately control interval of bar stocks and we can adopt discharging ways of artificial feeding and flexibility to meet the discharge. As the progre

4、ssive die has a higher demand on the progress of position, she chose the diagonal pair of guide pin positioning means. She used the mold of the main structure of the whole, punching press with the processing to meet the accuracy requirements between the punch and die. Die punch positioning method used riveting style structure. The process of mold design: First, through process analysis, we can determine the layout plan of the work piece (including: the division of steps, located ways of bar
