ABSTRACT:
A method of upsetting rivets with an electromagnetic riveter having a flat, high amperage capacity coil which impells the driver against the rivet, and attaining a short stroke for the coil, includes positioning the coil in contact with the face of the driver on one side of the coil, and in contact with a conductive transducer on the other side of the coil. A recoil mass is positioned on the side of the transducer opposite to its face in contact with the coil, and firm face contact is established between the transducer and the recoil mass. Hard mechanical contact is established between the coil, the driver, and the die, and a pulse of high amperage current is delivered to the flat coil through a power lead to generate a repulsive force between the coil and the transducer. The the force is transmitted from the coil, through the driver to the die to deliver a single, high power, short stroke impulse against the rivet to upset the rivet. The repelling force from the coil is reacted to the transducer and the recoil mass, which both recoil away from the coil and the driver. The energy in the transducer and recoil mass is absorbed in a relatively long stroke of a recoil air cylinder.
