Abstract

Bei einer Vorrichtung zum Befestigen eines stempelartigen Gegenhalters (6) oder eines Stanz- bzw. Lochstempels (6) zum Ausschneiden eines Ausschnitts aus der Wandung eines in einem Umformwerkzeug (1) nach dem Innenhochdruck-Umformverfahren hergestellten Hohlkörpers, wobei der Gegenhalter oder Stanzstempel (6) in einer Buchse (5) geführt ist, die von einer in dem Umformwerkzeug (1; 2) angeordneten Kulisse (4) aufgenommen ist, wird die Führungsbuchse (5) durch einen Klemmsitz im Werkzeug (1; 2) festgelegt. Weiterhin kann auch die Kulisse (4) durch Klemmung gehalten werden.

Figure 00000001
In the case of a device for fastening a stamp-like counter-holder (6) or a punch or punch (6) for cutting out a section from the wall of a hollow body produced in a forming tool (1) according to the internal high-pressure forming method, the counter-holder or punch (6 ) is guided in a bushing (5) which is received by a link (4) arranged in the forming tool (1; 2), the guide bushing (5) is fixed by a clamp fit in the tool (1; 2). Furthermore, the backdrop (4) can also be held by clamping.
