Abstract
A slider link press includes an oscillation link operating about a fulcrum shaft and an eccentric crank pin. A connecting link connects the oscillation link to a slide. The oscillating link and fulcrum shaft act to increase press torque, reduce downward press speed, and increases upward press speed thereby maintaining cycle time. The eccentric crank pin operates the oscillation link, aids in torque increase, and provides reciprocating movement to the slide. The slide includes pivotable slide gibs that engage reciprocal fixed gibs to maintain parallel surface contact and absorb and eliminate eccentric loads on the slide and the press. Stays and spacers align sides of the press and eliminate flexing under load while absorbing and distributing deformation pressure.
