石英管外壳多工位拉伸级进模设计

Design of Multipli-station Drawing Progressive Die for Quartzite Shell

根据石英管外壳材料10#的延伸性能和石英管外壳的尺寸要求确定它的拉伸次数和每级拉伸的拉伸系数，经过工艺分析进行了合理的排样。介绍了石英管外壳拉伸级进模模具的结构特点和模具的工作过程以及使用结果。

Based on the 10# material's extendability and size requirement ofquartzites shell, the drawing modulus and the drawing modulus in everydrawing are determined. After technology analyse, a reasonable blank layout ismade. Also, this paper introduces the structure character, workingproless anduse result of the die.
