Bei den bekannten Kaltupressen zur Herstellung von Nieten, Schrauben, Drahtstiffen u. dgl. besteht der Matrizenhalter ans einem prismatischen, im Längsschitt keilförmigen Körper, der von oben her in einen entsprechenden Aufschnitt, der Hinterwand des Maschinengestelles eingesetzt wird. Der

In the known cold presses for the production of rivets, screws, wire stiffeners and. The die holder consists of a prismatic, longitudinally wedge-shaped body, which is inserted from above into a corresponding cut in the rear wall of the machine frame. The

holder is formed as a cylindrical body, which is inserted from the front into a cylindrical recess "of the rear frame wall. This eliminates the fork in the frame wall and this is also closed above the die holder.
As a result, the frame wall can, without the risk of springiness or breakage as a result of the explosive pressure of the die or the pressure of the side
