ABSTRACT:
The present invention provides a small-sized slide adjusting device for use in a forging press manufactured by a simplified manufacturing process. An adjusting lever is provided with a nut receiving section, and a nut to be received in the nut receiving section is provided with turning shafts in axial alignment. A mounting hole is provided through two sides of the receiving section, a disc having an eccentric through hole is fitted in each mounting hole, and the turning shafts of the nut are fitted in a respective through hole. In one embodiment the nut is provided with a female screw situated at a right angle to the axial alignment direction of the turning shafts, and one end of the screw is connected to a motor mounted on a slide. In the slide adjusting device of this construction, a variation in height occurs due to the circular arc motion at the time of inclined movement of the adjusting lever making a center of a wrist pin a fulcrum followed by turning movement of the disc and turning shafts. Every slide adjusting movement which occurs is performed in a turning slide manner, whereby concentration of stress is alleviated resulting in a small-sized device.
