摘　　要：电磁铆接技术可以解决大直径、难成形材料铆钉铆接难题。与风动铆枪相比,由于增加了减振系统,导致电磁铆枪体积较大,一般只能用于结构开敞部位的铆接。为了解决电磁铆枪在不开敞结构中应用受限的问题,研制了铆枪与顶铁一体化的单人操作型电磁铆枪。首先,分析了电磁铆接工作原理;其次,开展了铆枪的钳形顶铁、铆钉夹持系统、铆枪减振系统与散热系统的结构设计,并通过有限元模拟分析验证了钳形顶铁的强度和刚度;最后,使用该铆枪进行了铆接能力试验,并测试了铆接力。试验表明,该铆枪可以成形Φ4 mm以下的钛铌铆钉,镦头尺寸有较好的重复性,并且该铆枪的结构强度也安全可靠。Electromagnetic riveting can solve the riveting problems of large-diameter and difficult-to-form materials.Compared with pneumatic riveting gun,generally the electromagnetic riveting gun with larger volume was only used for riveting in open structures due to the addition of damping system.Therefore,the development of electromagnetic riveting gun integrated with riveting gun and support iron operated by single person aimed at solving the problem that the application of riveting gun was limited in non-open structures.Firstly,this paper explained the operating principle of electromagnetic riveting,and then introduced the structural design of riveting gun including support iron,clamping system,damping system,and cooling system,as well as analyzed the strength and stiffness of the support iron through finite element simulation analysis.Finally,its riveting ability and the riveting force of titanium-niobium rivet of electromagnetic riveting were both tested.It was concluded that the riveting gun can generate as aΦ4 mm titanium-niobium rivet with good repeatability of header size,and the structural strength of the riveting gun is also safe and reliable.
