Abstract
A device for automatically adjusting die height in a press having a plurality of dies aligned in a work transfer direction includes a load pattern setting member for inputting possible load patterns, each pattern corresponding to the number of dies under load. A correction setting member is provided for inputting an amount of correction (compensation) by which the position of the bottom of the slide in each load pattern is rectified to a basic position corresponding to a basic load pattern. A pattern identifier is provided for identifying the current load pattern when the slide is at a given position. A correction controller is provided for selecting the proper amount of correction of the position of the bottom of the slide for the identified load pattern and sending a drive control signal corresponding to this amount to a slide position adjustment unit. A slide adjustment actuator is provided for actuating the unit to automatically rectify the position of the bottom of the slide at the bottom dead center of the press cycle to the basic position.
