Ultrasonic vibration assisted plastic forming has become an important research direction of plastic forming in recent years. In order to meet the installation requirements of ultrasonic equipments and workpiece, a 10 kN ultrasonic-assisted plastic forming press machine was designed and developed in this paper, which was based on the self-developed porous ultrasonic vibration platform. The control system and human-computer interaction interface of the press machine were designed and developed based on C++ language and Qt software platform. The ultrasonic stress softening test of T2 copper and the ultrasonic vibration assisted compression test of AZ31 magnesium alloy were carried out on the press machine. The experimental results show that the plastic forming press can meet the requirement of ultrasonic-assisted plastic forming. And the tool ultrasonic vibration can change the compression fracture characteristics of magnesium alloy effectively.
