An experimental study of V-ring position on the die roll height in the fine blanking of special part with corner shapes

摘要：

　　In this paper,the relation between die roll height and V-ring position of a fine blanking tool was studied by experimenting on a special part with various comer shapes.Three guide plate inserts with different V-ring positions and a die insert with constant die chamfer were machined,and a fine blanking tool was manufactured for the fine blanking experiments.Three experiments were conducted on a 650-ton fine blanking press.Each die roll height was measured and analyzed.We found the tendency of the die roll heights on the comer shapes of fine blanked parts to increase with increasing the distance between the V-ring position and the contour of the special part,and to decrease with increasing comer radius and angle.These results can be used to minimize the die roll height of fine blanking parts with comer shapes when designing the V-ring of a fine blanking tool.
