Abstract

Eine Presse, insbesondere eine Perforierpresse (1) ist mit einem Werkzeug (7) versehen, an dem mehrere Lochstempel (16, 17) verstellbar gelagert sind. Zur Arretierung der Lochstempel (16, 17) in Aktivposition dienen Arretiereinrichtungen (31, 32), die zum Verändern der Auswahl durch eine Entlastungseinrichtung (51) freigegebenen werden, wenn die Lochstempel (16, 17) außer Eingriff mit dem Werkstück (9) sind und sich in einem gewissen Sicherheitsabstand zu diesem befinden. Die Entlastungseinrichtung ermöglicht eine leistungsarme und dennoch schnelle Verstellung der Arretiereinrichtungen (31, 32) und somit eine Veränderung der Lochstempelauswahl bei jedem Pressenhub auch bei schnelllaufenden Pressen. Eine Vorspannung der Lochstempel (16, 17) auf ihre Passivposition hin gestattet die Vermeidung von Berührungen zwischen passiven Lochstempeln (16) und dem Werkstück (9) während des Pressenhubs. Dies vermeidet Werkstückbeschädigungen.

Figure 00000001
A press, in particular a perforating press (1), is provided with a tool (7) on which a plurality of punches (16, 17) are adjustably mounted. Locking devices (31, 32) are used to lock the punch (16, 17) in the active position, which are released for changing the selection by a relief device (51) when the punch (16, 17) is out of engagement with the workpiece (9) and are at a certain safety distance from it. The relief device enables the locking devices (31, 32) to be adjusted quickly and with little power and thus a change in the punch selection with each press stroke, even with high-speed presses. Preloading the punch (16, 17) to its passive position allows contact between passive punch (16) and the workpiece (9) to be avoided during the press stroke. This avoids damage to the workpiece.
