摘要
为解决传统电磁翻边能量利用率低、翻边角度不理想等问题,提出一种同时加载的管-板电磁翻边技术。针对特定的铝管(A6061-O),首先采用Comsol Multiphysics建立同时加载的管-板电磁翻边过程的电磁-结构耦合模型,然后通过分析线圈参数实现对工件电磁力分布的调控,最后对比研究了理想线圈参数下3种仿真模型的驱动线圈电流、磁通密度、电磁力分布、能量利用率与翻边角度。模拟结果表明:在相同放电电压下,同时加载的管-板电磁翻边的能量利用率为27.97%,较传统管件电磁翻边提高了180.82%,较传统板件电磁翻边提高了41.26%。在相同初始储能下,同时加载的管-板电磁翻边模型能促使管件与板件同时翻边至90°,而传统电磁翻边模型仅能使管件与板件同时翻边至16°。显然,同时加载的管-板电磁翻边技术能有效提高能量利用率与翻边角度。
To solve the problems of low energy utilization rate and unsatisfactory flanging angle of traditional electromagnetic flanging,a tube-plate electromagnetic flanging technology with simultaneous loading was proposed.For a specific aluminum tube(A6061-O),the electromagnetic-structural coupling model of the tube-plate electromagnetic flanging process under simultaneous loading was first estab-lished by Comsol Multiphysics and then the distribution of the workpiece electromagnetic force was controlled by analyzing coil parameters.Finally,the driving coil current,magnetic flux density,electromagnetic force distribution,energy utilization rate and flanging angle of the three simulation models with ideal coil parameters were compared.The simulation results show that under the same discharge voltage,the energy utilization rate of simulataneously loaded tube-plate electromagnetic flanging is 27.97%,which is 180.82%higher than that of tra-ditional tube flanging and 41.26%higher than that of traditional plate flanging.Under the same initial energy storage,the simulataneously loaded tube-plate electromagnetic flanging model can make the tube and plate flanging to 90°,while the traditional electromagnetic flan-ging model can only make the tube and plate flanging to 16°.Obviously,the simultaneously loaded tube-plate electromagnetic flanging technology can effectively improve the energy utilization rate and flanging angle.
