Abstract:
A slide inclination correcting apparatus in press machinery having a slide drive mechanism disposed in a top area of a press body for driving a slide via a plurality of points to vertically move it up and down, thereby forming a work piece, the apparatus comprising:a die based slide inclination correcting data acquisition means for acquiring a die based slide inclination correcting data by finding by measurement or computation for each of dies or die sets an eccentric load that is to develop in the slide in the process of forming a work piece; a slide adjustment mechanism provided for each of said points; and a slide inclination correction means for pre-imparting to the slide a compensatory amount of inclination corresponding to a predicted amount of inclination caused by the slide due to the eccentric load, by driving said each slide adjustment mechanism on the basis of the die based slide inclination correcting data acquired by said die based slide inclination correcting data acquisition means.
