In a press forming machine for pressing a slide plate, which has a movable mold thereon, by using a plurality of driving sources, a control unit is disclosed, in which when offset load is applied on the slide plate, molding can be performed while the slide plate is maintained at a desired position relative to a fixed mold. In the press forming machine, engaging parts corresponding to the driving sources are provided on the slide plate, and displacement measuring units for measuring a displacement of the slide plate are provided near the engaging parts.; The control unit includes a unit which measures a displacement of each of the driving sources by using the displacement measuring unit in each of a plurality of operating steps during a molding operation, detects a desired displacement position of the entire slide plate in each of the steps, extracts control data corresponding to the driving sources to maintain the entire slide plate at a desired displacement position, stores the control data in a memory, supplies the control data to the driving sources, and separately drives the driving sources. Since actual molding can be performed by using control data generated in a trial molding, it is possible to shorten cycle time of the actual molding.
