The deformation segment (2) is arranged between the setting head (4) and the shank end (3). The fastening element (1) is hollow, optionally having a mandrel (7) inside the fastening element (1). The mandrel includes a head (23) and a foot (24) at least tension-resistantly connected to the shank end (3). The shank end (3) includes a punching edge (6) extending substantially along the outermost periphery of the shank end (3). Also identified are a process for setting the fastening element (1), a riveted connection to the fastening element (1), a device for setting the fastening element (1), an employment of the riveted connection obtained, and a die suitable for setting the fastening element (1).
CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Continuation of International Application No. PCT/DE02/00764, filed Mar. 1, 2002. This application claims the benefit of German Patent Application 10160771.7 filed Dec. 11, 2001, German Patent Application 10121218.6 filed Apr. 30, 2001, and German Patent Application 10111692.6 filed Mar. 9, 2001. The disclosures of the above applications are incorporated herein by reference.
FIELD OF THE INVENTION The invention relates to a fastening element, in particular a blind rivet, having a setting head, a deformation segment and a shank end, and to a process and device for setting the said fastening element, a punch die, the riveted connection made by the process and/or device, and an employment of said riveted connection.
BACKGROUND OF THE INVENTION Numerous types of rivets are known in the art. Blind rivets are distinguished in that the force required to set the blind rivet is not applied by force-absorbing stirrups on either side of a part to be riveted, but the head and foot of the rivet are pressed together by pulling on a mandrel passing through the interior of the blind rivet, the head being held at the part and the foot pulled towards the head by means of the mandrel.
The advantage of the blind rivet consists in that access to only one side of the work is required. Various �designs� have been developed for self-drilling blind rivets, but the creation of self-piercing blind rivets has not been considered, since the necessary deformability of the shank does not permit exertion of a piercing force.
SUMMARY OF THE INVENTION This object is accomplished, according to the invention, by a fastening element having the features of the claims. Advantageous embodiments and modifications, that may be adopted singly or in combination with each other, are the subject of the various dependent claims.
BRIEF DESCRIPTION OF THE DRAWINGS Other special embodiments and advantages of the invention are illustrated with reference to the accompanying drawings. The drawings are to be understood as an exemplary instance of the invention, not intended to limit the invention in its spirit and significance.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a fastening element 1 according to the invention, having a setting head 4, a deformation segment 2 and a shaft end 3 with an internal thread 5 and a punching edge 6, hollow, into which a mandrel 7 having a head 23 and a foot 24 is screwed. The tension-resistant connection between the mandrel 7 and the shank 27 is made by means of a connecting segment 28. The connecting segment 28 is made up of an internal thread 5 in the shank 27. The internal thread 5 is screwed onto an external thread 29 on the mandrel 7. The fastening element 1 is punched through a first part 8 and a second part 9, the two parts 8, 9 having the aspect of sheets lying one upon another. The fastening element 1 punches its own hole 11 through the parts 8, 9. The shank end 3 and part of the deformable segment 2 are located in the rear 10 of the second part 9. The deformation segment 2 has a thin wall thickness compared to the shank end 3. The mandrel 7 includes a head 23, to which firstly accessories 22 (not shown) can be fastened, and with which the mandrel 7 can be drawn towards the setting head 4. The setting head 4 rests firmly on the first part 8.
