In order to process micro scale parts more conveniently, especially the micro parts with complex shape, a new micro blanking equipment based on piezoelectric ceramic driving is proposed in this paper. Compared with other large precision machining equipment, the equipment cost has been greatly reduced. Using displacement sensor to detect the change of output displacement and feedback control piezoelectric actuator to control the change of relevant parameters, the control precision is high. The micro gear parts with diameter less than 2 mm are obtained through the blanking experiment on the experimental equipment. From the relationship between the obtained time and the punch output force, output displacement and die adjustment, it can be seen that the designed equipment has good processing performance and can complete the blanking forming of micro parts well.
为了更方便地加工微尺度零件，特别是形状复杂的微零件，本文提出了一种基于压电陶瓷驱动的新型微冲裁设备。与其他大型精密加工设备相比，设备成本大幅降低。利用位移传感器检测输出位移的变化，并通过反馈控制压电致动器来控制相关参数的变化，控制精度高。通过在实验设备上进行冲裁实验，获得了直径小于2mm的微齿轮零件。从所得时间与冲头输出力、输出位移以及模具调整之间的关系可以看出，所设计的设备具有良好的加工性能，能够很好地完成微零件的冲裁成形。
