摘　　要：电磁铆接工艺成形机理不同于普通铆接,需要对其工艺参数及力学性能进行研究和分析。本文基于便携式电磁铆接设备HH54系统,针对Φ4 mm、Φ5 mm、Φ6 mm直径的铝合金铆钉进行铆接工艺研究,得出钉孔直径、钉杆外伸量和充电电压等工艺参数;通过选取合适的工艺参数,进行了电磁铆接力学性能及微观金相试验,证明了电磁铆接代替手工锤铆的可行性。The forming mechanism of the electromagnetic riveting process is different from that of ordinary riveting, and its process parameters and mechanical properties need to be researched and analyzed. In this paper, the riveting process of aluminum alloy rivets with diameters of Φ4 mm, Φ5 mm, and Φ6 mm based on the HH54 system of portable electromagnetic riveting equipment was studied, and the process parameters such as nail hole diameter, nail rod extension, and charging voltage were presented;by selecting suitable process parameters, the mechanical property and micro metallographic analysis of electromagnetic riveting were conducted, which proved the feasibility of electromagnetic riveting instead of manual hammer riveting.
