The invention relates to a rivet element (10) to be fastened to a component (51), in particular to a fiber composite component. Said rivet element has a flange portion (21), which, when fastened, rests against the component, and a rivet portion (11). The rivet portion comprises a tip (12a), converging away from the flange portion, a flared end portion (12b) being provided at the end of the tip which is remote from the flange portion.

A hollow punch rivet is described having a flange and a rivet section. Furthermore, a method for the attachment of individual components to one another using a punch rivet is described, with at least one of the components being formed by a material of the composite material. The method includes the following steps: a) arrangement of the die button against one of the two components to be secured to one another, which are placed on one another, wherein the die button has a bore which is dimensioned to receive the rivet section, b) carrying out a relative movement of the punch rivet with the free end of the rivet section to the fore towards the components arranged on one another and in the direction of the die button, c) piercing of the components with the free end of the rivet section and introduction of the rivet section into the bore of the die button until the component contact surface comes into contact and the component adjacent to the flange, d) using a plunger in order to dilate the punch rivet at least locally and e) forming a rivet bead by reshaping the free end region of the rivet section.

In a method for fastening a rivet element (1) to at least one workpiece (W) a rivet element (1) is used that has has a hollow shank (2), a punch head (5) at one end of the shank (2), a flange (8) at a distance from the punch head (5), and a deformation region (9) between the flange (8) and the punch head (5). By means of a cylindrical mandrel (15) of a fastening device (20), the punch head (5) of the rivet element (1) is pressed through the workpiece supported on a first dolly (12), thereby forming a rivet hole. Subsequently, by means of a riveting die (17) directed toward the punch head (5), the deformation region (9) of the shank (2) is formed into a closure flange (18) contacting the workpiece (W), wherein the flange of the rivet element (1) is supported on a second dolly (14).

Die Vorrichtung dient zur Durchführung eines Setzvorgangs zum Setzen eines Verbindungselements (4) an einem Werkstück (6), wobei der Setzvorgang im Betrieb durch eine Steuervorrichtung gesteuert wird, Die Vorrichtung weist eine Setzeinheit mit einem Setzkopf (36) sowie eine Matrize (22) auf, gegen die der Setzkopf (36) in Richtung zum Werkstück (6) in einer Zustellrichtung verfahrbar ist. Die Matrize (22) weist einen Grundkörper sowie einen in diesem verschieblich angeordneten Matrizenstempel (26) auf, der im Betrieb als Widerlager beim Setzen des Verbindungselements (4) dient und/oder mit dessen Hilfe im Betrieb eine Umformung des Verbindungselements (4) zur Ausbildung einer formschlüssigen Verbindung mit dem Werkstück (6) erfolgt. Der Matrizenstempel (26) ist entgegen der Zustellrichtung mithilfe eines Antriebsmechanismus gesteuert verstellbar.
