Abstract

The invention relates to an ultrasonic-assisted micro-imprint forming device and a micro-imprint forming method. The device comprises an ultrasonic power supply, an ultrasonic transducer, an ultrasonic amplitude-change pole and a porous ultrasonic amplitude transformer, wherein the ultrasonic amplitude-change pole and the porous ultrasonic amplitude transformer are connected in series in sequence through a connecting bolt, wherein the lower end surface of the ultrasonic amplitude transformer is connected with a support leg through a thread; the support leg supports the entire device; the upper end surface of the ultrasonic amplitude transformer is connected with a lower puncher pin through a connecting bolt; a workpiece is fixed to the lower puncher pin; a micro-imprint mold is fixed to an upper puncher pin. In micro-imprint forming, input horizontal ultrasonic vibration is converted into vertical ultrasonic vibration through the porous ultrasonic amplitude transformer, and a micro-imprint forming mold and the workpiece are driven to vibrate vertically together at high frequency, so that vertical ultrasonic-assisted micro-imprint forming is realized. Vertical ultrasonic vibration of the micro-imprint forming device can be realized at a small spatial height, and an ultrasonic micro-imprint forming process is finished. By adopting the device and the method, the implementation of an ultrasonic micro-imprint forming technical process is facilitated, and the micro-imprint forming process and the quality of a material are improved.
