摘要
应用粉末烧结材料广义塑性理论,研究和建立了该材料的镦粗、复压、闭式模锻变形力和工件密度、尺寸计算式。分析了粉末烧结材料镦粗和复压工艺的致密效果,提出了闭式模锻工艺设计原则。
The calculation formulae of deformation pressure,workpiece density and sizes for upsetting,repressing,and closed die forging are derived based on the generalized plasticity theory of sintered powder materials.The densification effects of upsetting and repressing are compared,and a technology design principle for closed die forging is suggested .
