10 kN超声辅助塑性成形压力机设计与试验

超声辅助塑性成形近年来已经成为塑性成形领域的重要研究方向。为了满足超声辅助塑性成形过程中的超声设备与工件安装需求，在自行研制的多孔超声振动平台基础上，设计开发了10 kN超声辅助塑性成形压力机。采用C++语言和Qt软件平台开发了压力机的控制系统及人机交互界面，并利用该压力机进行了T2紫铜超声应力软化试验和AZ31镁合金超声辅助压缩试验。结果表明，所设计的压力机可满足超声辅助塑性成形需求，工具辅助超声振动可有效改变镁合金的压缩断裂特性。 

Design of 10 kN ultrasonic-assisted plastic forming press machine and experiment

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.
