摘要：

针对电磁翻边成形技术成形效率低的问题，提出了双板件电磁翻边成形技术。在阐明双板件电磁翻边成形原理的基础上，构建了传统单板和双板件两组仿真模型，并从驱动线圈电流波形、磁通密度、电磁力、塑性应变能、成形效率5个方面进行对比分析。结果表明：在相同的放电能量下，双板件仿真模型的塑性应变能比传统单板提高了52.28%；在相同的翻边角度下，双板件仿真模型所需的放电能量仅为传统单板仿真模型两次放电能量的60.60%，能量利用率提高了39.40%。双板件电磁翻边成形技术可使用单个驱动线圈同时实现两个板件的翻边，能够有效地解决电磁翻边成形效率低的问题，促进了电磁翻边成形技术在工业领域的广泛运用。

For the problem of low forming efficiency for electromagnetic flanging technology, the electromagnetic flanging technology of double-sheet was proposed. Then, on the basis of clarifying the principle for electromagnetic flanging of double-sheet, two simulation models of the traditional single-sheet and double-sheet were constructed, and the five aspects of driving coil current waveform, magnetic flux density, electromagnetic force, plastic strain energy and forming efficiency were compared and analyzed. The results show that under the same discharge energy, the plastic strain energy of the double-sheet simulation model is 52.28% higher than that of the traditional single-sheet, and at the same flanging angle, the discharge energy required by the double-sheet simulation model is only 60.60% of the two discharge energies for the traditional single-sheet simulation model, so the energy utilization rate is increased by 39.40%. Obviously, the electromagnetic flanging technology of double-sheet can use a single drive coil to realize the flanging of two sheets at the same time, effectively solves the problem of low forming efficiency for electromagnetic flanging and promotes the wide application of electromagnetic flanging technology in the industry field.
