概要

• The bending deformation of material under the punch at the shearing time causes a deflection of sheared blanks. Moreover, because of the spring back of the bending, the diameter of sheared blanks is not always equal to the diameter of the die hole. The authors, in this paper, analyzed the bending moment and the axial force, which cause the deflection of the material, and made clear the effect of spring back on the dimensional accuracy. These analytical results were also confirmed by experimental results.
