PURPOSE: To obtain a titled automatic adjusting device which is capable of setting the die height with high accuracy, by automatically stopping a slide adjusting motor when a load value converted from detecting pressure of an oil pressure chamber of a slide for constituting a part of an overload safety device, etc. of a press reaches an optional set value set in advance.

CONSTITUTION: When adjusting the die height, a metallic die is carried into a press in the way as a conventional case, and after that, a slide is made to descend by starting a slide adjusting motor 26. As the slide descends, it contacts with a punch, but its descent is maintained continuously thereafter. Therefore, a load increases, pressure of an oil pressure chamber 1 rises, and a display load of an display 17 increases gradually. Subsequently, when this load reaches a set value of a digital setting device 20, an output of a comparator 21 becomes on, and a relay 23 is driven through a relay driver 22. Accordingly, a stop signal is supplied to the motor 26 and the slide is stopped. Also, after the slide stops, the punch is clamped, and the slide is then returned to the top dead center, by which the die height adjustment is finished.
