Abstract
A slide guide for a press comprises a pair of sliding surfaces for slide side and frame side arranged at four corners at the left and right sides as well as the front and rear sides of the press slide to maintain the set clearance constant and each slide's side sliding surface is provided with acclivities, parallel faces and declivities alternately in the sliding directions which produces a wedge-shaped oil film thereon and the effect of the wedging action of the oil film is heightened by properly setting a wedge angle formed by the acclivities and declivities in accordance with the slide's ascending/descending speeds so that the oil film generates a separating force to wedge off the slide side and frame side sliding surfaces, thereby enabling the slide's high speed motions to remain highly accurate without producing oil film breakdown even when the clearance is set minimal. The clearance is adjustable by adjusting devices and lubricant is applied to the sliding surfaces by a forced circulatory lubrication system.
