A slide driving device for use in a metal working press having an eccentric sheave capable of effecting an eccentric rotation and an oscillating link member adapted to oscillate in response to the eccentric rotation of the eccentric sheave. A slide of the metal working press is connected with the oscillating link member through a connecting rod. The eccentric sheave is adapted to be eccentrically rotated at uneven angular velocities so that the downwardly moving speed of the slide is reduced relative to the operating speed of the press which is supplied with power from the driving power source. |
