Abstract：

For the quality problem in the titanium alloy sheet bending process, especially springback, an ultrasonic vibration assisted bending method was proposed by superimposing the ultrasonic vibration with a certain direction, a certain frequency and amplitude to the die in the bending process, and the V-bending process of titanium alloy TC1 sheet was studied, which is greatly affected by springback. Then, the influences of ultrasonic vibration frequency, amplitude and vibration time on bending force and springback of titanium alloy TC1 sheet were analyzed. The results show that the titanium alloy TC1 sheet superimposed the ultrasonic vibration with a certain frequency, amplitude and vibration time in the V-bending process can effectively reduce bending force and specimen springback, and the bending performance of titanium alloy sheet is effectively improved. Thus, the feasibility of ultrasonic vibration to improve the bending performance of titanium alloy sheet is also verified.
