Summary:The invention relates to a forming device for plate riveting based on electromagnetic pulses. Electromagnetic forming can increase the material forming limit and improve the rivet forming effect. Theriveting forming device comprises a bottom plate, a guide seat, an upper plate, a guide plate, a pillar, pier head upper and lower dies, a flat plate spiral coil, a guide rod, a punch, a driving plate, a pressing block and a forming rivet. The invention also provides a forming method using the device. The forming method comprises the steps that 1, a rivet passes through a metal plate provided witha through hole in a drilled manner and is fixed through the pressing block; 2, the rivet is kept perpendicular with the pier head lower die, so that one side of a rivet head is in sufficient contactwith the pier head lower die, and the other side of the rivet head is in contact with the pier head upper die; 3, forming of the rivet is completed; and 4, a riveting forming part is taken down. By means of the forming device a
