Abstract：

Experimental mold of closed extruding-type fine-blanking process was first designed and made based on the mechanism and technology of closed extruding-type fine-blanking.And then through the experiments conducted with blanks of different thicknesses and diameters,the relationships between outer filling rate and brightness ratio of shear plane as well as the thickening of workece in the closed extruding fine-blanking process were analyzed.Finally,the calculating method for working portion of die was obtained.Experiments show that the closed extruding-type fine blanking is an effective process making the materials with low-plastic and plate.
