Abstract

The application of ultrasonic vibrations superimposed on wire drawing, deep drawing, upsetting and rolling has been developed in the literature. No attempts have ever been made to develop the application of the ultrasonic vibration to blanking process. This paper reports an investigation into the effects of the superimposed ultrasonic vibrations of the die during the blanking process by finite element software DEFORM-2D. The results are compared with the conventional blanking experiment by Hatanaka and Yamaguchi [7] and the simulations are analyzed with various vibration directions, amplitudes and frequencies. The effects of the ultrasonic vibration on the punch load, flow stress and edge profile are systematically studied. The results show ultrasonic vibration can decrease the punch load and improve the quality of edge profile by increasing the vibration amplitudes and frequencies.
