支撑件、汽车一支撑架零件的冲压模具设计-支撑件级进模含开题及11张CAD图,文本

内容简介：

支撑架零件冲压模具设计摘 要本次设计内容是关于对给定的工件设计冲压模具，其给定工件是某汽车一支撑架零件，分析该工件结构特征，对工件进行展开和计算，查阅相关资料和对工件结构特征仔细分析选择采用多工位级进模，多工位级进模能提高生产效率，保障操作的安全。根据工件结构和展开图设计工件排样方案，确定排样工位、条料宽度、步距和搭边。工件在加工过程中有一次两边90度弯曲和四次单边45度弯曲，为能实现这些弯曲需要采用斜楔滑块机构。由于工件结构比较复杂，所用排样工位有些多，该模具体型相当的大，许多模具零件不能找到合适规格，需要按设计要求设计相应零件。关键词：级进模，排样设计，斜楔滑块机构 Brace parts stamping die designABSTRACTThis graduation design is about for the given workpiece stamping die design, the workpiece is given some car a support frame parts, analyzed the structure characteristic of workpiece, to expand and calculation of workpiece, consult the relevant data and careful analysis to choose the workpiece structure using multi-station progressive die, multi-station progressive die can improve the production efficiency, guarantee the safety of the operation. According to the workpiece structure and layout for graph design artifacts, determine the layout location, strip width, interval, and on. Workpiece in machining process on both sides of a 90 - degree bend and unilateral 45-degree bend, four times in order to achieve these bending need to adopt wedge slide block mechanism. Due to the workpiece structure is complicated, the used layout location in some more, the mold size is quite big, many cannot find an appropriate specification mould parts, need to design the corresponding parts according to design requirements.
