ABSTRACT:
A press for applying impact forces to a work object includes a horizontal resonant beam having an output end for applying the impact forces. The beam is secured to a frame at two nodal points, one of which may be moved up and down by a hydraulic cylinder. The beam is excited by an eccentric weight oscillator and the output end of the beam is urged against the work object by the cylinder. In operation, the force applied by the cylinder to the beam should be maintained less than the oscillator force so that the output end of the beam does not freeze against the work object, causing the beam to enter a forced resonant mode.
