Ram-side ejector device for workpieces in single-or multi-stage presses

Abstract

A ram-side ejector device for shaping presses comprising a press carriage, which is movable between a pressing position extended relative to a stationary press die and an end position at a distance therefrom and comprises a press ram cooperating with the stationary press die, said presses further comprising an ejector pin carried on the press carriage the pressing direction and penetrating the press ram, said ejector pin being movable between a retracted end position, in which it is supported, by its end remote from the die, on a stop formed on the press carriage, and an extended position protruding from the press ram, wherein the end of said pin remote from the die is distanced from the stop, said pin being provided with a resetting means which acts counter to the direction in which said pin is extended and which may be releasably blocked, when the press carriage returns from its pressing position, by a blocking means fixed to the press frame counter to the return movement of the press carriage, the activation or deactivation of the blocking means and the activation of the resetting means being program-controlled and coupled with each other, characterized in that the blocking means comprises a positionally adjustable blocking element, which may be retracted into blocking engagement with the ejector pin or with a part connected therewith, while the ejector pin contacts the stop.
