摘要
电磁铆接是一种新兴的高能量铆接技术,其加载速率快、效率高,钉杆受力均匀,能够形成较好的干涉配合;但由于能量高与加载速率快的问题,极易造成钉杆裂纹、镦头质量不佳以及被铆接材料损坏等现象。实验采用Ansoft Maxwell有限元分析建立铆接模型,对铆接线圈加载电压以及受力情况进行分析。再对公称直径5mm的304不锈钢铆钉进行电磁铆接工艺试验。针对仿真与实验结果的比对,调整工装结构并确定不锈钢铆钉最佳铆接电压的范围,形成较好的铆接镦头,铆钉与被铆接板材实现了较好的干涉配合。
Electromagnetic riveting is a new kind of high energy riveting technology,which has the advantages of fast loading rate,high efficiency and uniform force,and it can form a good interference fit.However,due to the high energy and fast loading rate,it is easy to cause the crack of nail rod,poor upsetting quality and damage of rivet material.The riveting model is established by Ansoft Maxwell finite element analysis,and the loading voltage and force of riveting coil are analyzed.The electromagnetic riveting process of 5mm stainless steel rivets with nominal diameter was tested.According to the comparison between the simulation and the experimental results,the tooling structure is adjusted and the stainless steel rivets are determined.The range of riveting voltage forms a better riveting riveting head,and the rivets and riveted plates achieve better interference fit.
