Abstract

Es wird eine Verriegelungsvorrichtung für hydraulisch angetriebene, einfach- oder doppeltwirkende Pressen (1) zur Hochdruckumformung vorgeschlagen die wesentlich zur Erhöhung der Bauteilsteifigkeit insbesondere des Kopfstücks oder Oberholm (5) beiträgt. Durch Anordnung der Riegel (11) auf der Oberseite der Umformstössel (4) kann für die Bauhöhe der Riegel (11) der komplette Schliesshub genutzt werden.

Figure 00000001
A locking device for hydraulically driven, single-acting or double-acting presses (1) for high-pressure forming is proposed, which contributes significantly to increasing the component rigidity, in particular of the head piece or upper spar (5). By arranging the bolt (11) on the top of the forming plunger (4), the complete closing stroke can be used for the overall height of the bolt (11).
