Research on Flow Mechanism of Material for Spur Gear in Closed Extruding Fine blanking Process

摘要：

　　The finite element method (FEM) is applied to analyze closed extruding fine blanking gear.The reason of engendering corner collapse is the friction between blank and die.Meanwhile,this paper analyzes effects of various counterpunch forces on the flow characteristics,obtains the fiber distribution on different sections of the gear.The effects of counterpunch forces on material flow characteristics in deformation zone and the swirling flow in scrap are also obtained.
