摘 要
在工业发展大步向前迈进的中国,冲压工艺也在不断发展中占据着越来越重要
的地位。此次设计首先通过计算坯料的尺寸, 明确拉深的次数, 最终确定了完成工件
的加工需要两次拉深。 在这之后以目标工件即法兰件为准, 在分析了目标工件和拉深
工艺的基础上, 根据工序设计要求以及对比了常见的三类模具的优缺点, 在其中选择
了复合模具完成落料拉深工序。 在之后的设计中, 计算了要如何排样, 计算各个重要
的力,还设计了要如何把板料冲裁为坯料的方案。 在之前的计算和设计的铺垫下, 这
之后很顺利地计算和设计了模具零件的部分尺寸,如工作部分凸、凹模的刃口尺寸,
并根据标准对一些数据进行校核。 然后根据参考资料和标准设计了其他模具零件, 如
定位零件, 卸料零件等等。 在进行了以上计算和设计的基础上, 最后绘制出了模具的
装配图和零件图。

ABSTRACT
As the Chinese industry continues to develop, stamping process is being more
and more important. In this paper, three different stamping processes (single process,
posite process and continuous process) of the forming process are pared and analyzed
for the punching processand drawing processof the wide flange cylindrical parts.
And selected the posite process .The shape, size, nesting, cutting plate scheme, the
number of times of drawing, the nature, number and order of stamping processare
briefly analyzed. It was determined that two deep drawing is required.The work force,
pressure center, mold part of the work size and tolerance calculation, and design of
the mold. But also the specific analysis of the main parts of the mold (such as convex
and concave die, unloading device, drawing punch, plate, punch fixed plate, etc.)
design and manufacturing, convex and concave mold gap adjustment. A detailed list
of the parts required for the mold is listed and a reasonable assembly drawing and part
drawing are given.
Key words : blanking; drawing; posite mold; flanges
