Abstract

Ein Stanz-Prägewerkzeug weist eine in einer Bohrung eines Preßstempels (5) verschiebbare Nietnadel (4) auf. Das Werkzeug besteht aus einem Hydraulikzylinder (1) mit zwei Kolben (2, 3), bei denen der eine Kolben (2) die Nietnadel (4) und der andere Kolben (3) den Preßstempel (5) trägt. Der Raum (8) zwischen den Kolben (2, 3) ist mit einem volumenveränderlichen Druckraum (16) verbunden. Der Zylinderraum, der dem einen Kolben (2) zugewandt ist, ist mit einem Druckzylinder (12) verbunden. Nachdem ein Niet unter die Nietnadel (4) zugeführt wurde, wird der Druckzylinder (12) aktiviert und eine Drossel (15) zwischen dem Raum (8) zwischen den Kolben (2, 3) und dem Druckraum (16) zwischengeschaltet. Hierbei wird der Stanzvorgang ausgeführt und sodann der eine Kolben (2) in Richtung des anderen Kolbens (3) gedrückt, wobei dann zur Ausführung des Prägevorgangs der eine Kolben (2) auf dem anderen Kolben (3) aufliegt.

Figure 00000001
A stamping and embossing tool has a rivet needle (4) which can be displaced in a bore in a press ram (5). The tool consists of a hydraulic cylinder (1) with two pistons (2, 3), in which one piston (2) carries the rivet needle (4) and the other piston (3) the press ram (5). The space (8) between the pistons (2, 3) is connected to a volume-variable pressure space (16). The cylinder space facing the one piston (2) is connected to a pressure cylinder (12). After a rivet has been fed under the rivet needle (4), the pressure cylinder (12) is activated and a throttle (15) is interposed between the space (8) between the pistons (2, 3) and the pressure space (16). The stamping process is carried out and then one piston (2) is pressed in the direction of the other piston (3), with one piston (2) then resting on the other piston (3) in order to carry out the stamping process.
