摘　　要：介绍了抽油杆工艺特点及抽油杆镦锻成形工序过程。依据成形过程,基于三维刚-黏塑性有限元的理论,利用有限元软件对抽油杆镦锻成形各工步进行了数值仿真模拟。得到了抽油杆镦锻成形各工步的应力、应变、损伤场等的变化规律,为抽油杆镦锻成形提供了直观设计依据和经验。In order to study the technological characteristics of the sucker rod and its upsetting forming processes. Based on the forming process and three-dimensional visco-plastic finite element theory,carried out numerical simulation of each rod upsetting forming stage by finite element method,and obtained the law of stress,strain,strain variation of velocity field during the forging process,which provides design basis for rod upsetting.
