摘要为了提高微尺度金属零件的成形效率和精度，开发了一种将加热和振动相结合的高能辅助微成形系统。该系统包括一个桌面伺服压力机系统，可以提供各种运动，包括步进和振动运动和电阻加热系统与接触电极探头嵌入模具，能够加热工件和实时控制。通过微拉深和微锻造试验对高能辅助成形的性能进行了评价。成形性被发现显着改善，和表面粗糙度改善，由于改善的流动性和变形均匀性。
ABSTRACT A high-energy-assisted microforming system, which combines heating and vibration, was developed to improve the efficiency and accuracy of microscale metal parts. The system consists of a desktop servo-press system that can supply various motions including step and vibration motions and a resistance-heating system with contact electrode probes embedded in the dies that are capable of heating only the workpiece and of real-time control. Microdeep drawing and microforging was conducted to evaluate the performance of the high-energy assistance. The formability was found to improve significantly, and the surface roughness improves due to improved flowability and deformation uniformity.
