摘　　要：毫米结构零件是指尺寸在1mm到20mm之间的零件,它介于宏观尺度和微观尺度之间。通过分析指出了毫米级零件拉深模具设计与制造过程中最大的难点在于凸、凹模对中定位问题。对传统设计做了一些修改,采用压边部件进行导向定位以及活动凸模,很好的解决了这一问题。Milli-structure components are classified as a component group for which the size is between macroand micro-scales, i.e., less than about 20ram and larger than lmm. That the biggest difficulty in design and manufacturing of deep drawing die for milli-eomponent is to align the centers of punch and die has been presented on the basis of analysis,which has been solved by orienting and aligning through the blank holder and using of active punch.
