Research on Flow Mechanism of Materials and Micro-State of Distortion Area in Closed Extruding Fine Blanking Process
There are some differences between traditional fine blanking and closed extruding fine blanking in stress, separation process and change of material's performance. The article researched the micro-state's characteristics and deformation law in closed extruding fine blanking process, through observing the closed extruding fine blanking parts' metallographic, flow lines of deformation zone and analyzing the micro-hardness.
