摘　　要：为实现微孔冲裁高效、高质量加工,避免微冲头、冲模孔离线加工而引起的二次装夹问题,在实验室自行研制的微细电火花加工机床上进行微冲裁加工装置的设计。利用该装置进行微冲头、冲模孔的在线制备和冲裁加工试验,成功制备出了直径100μm的微冲头与直径110μm的冲模孔。并在厚度20μm的黄铜箔上冲裁出直径105μm的微孔,验证了该装置的可行性。A micro-hole punching device based on the self-developed micro-EDM tool is designed in this paper. The purpose is to realize micro-punching with high efficiency and quality, and avoid the secondary clamping error of micro-punch and punching die hole caused by offline processing. Micro- punch and punching die hole online preparing experiments and punching of micro-hole are carried out on the designed micro-hole punching device. A micro-punch and punching die hole with a diameter of 100 μm and 110μm are fabricated successfully. A micro-hole with a diameter of 105μm is punched in the brass sheet for 20μm in thickness. The feasibility of the micro-hole punching device is verified. Key words： micro-hole ;micro-EDM; micro punching; online preparation
