ABSTRACT:
The apparatus includes a driver (86). The driver (86) includes a front portion (90) which is adapted to receive a riveting die (92), and a rear portion (88) which is a copper plate. The copper plate (88) is receptive to the establishment of magnetic field currents therein. The actuator further includes a coil (72) which is positionable in close proximity to the copper plate (88) of the drive (86). The apparatus further includes a bank of capacitors having a stored charge so as to produce a current pulse through the coil (72) when the capacitors are connected to the coil (72). Still further, the apparatus includes a control means for selectively connecting the stored charge from the capacitors to the coil. The copper plate (88) is relatively thick compared to that used in high voltage electromagnetic actuators, such that the present apparatus requires only a relatively low voltage in order to produce the required high forces to accomplish the desired riveting.
