Embodiment Construction

[0059] figure 1 A schematic view in longitudinal section of a first embodiment of a blind rivet arrangement according to the invention is shown, generally designated by the reference numeral 10 .

[0060] The blind rivet set 10 includes a rivet body 12 and a rivet mandrel 14 . The blind rivet arrangement 10 may be used to join a workpiece arrangement comprising at least one first workpiece 16 (visible side workpiece) and one second workpiece 18 (blind side workpiece).

[0061] The rivet body 12 comprises a rivet head 20 in known manner comprising a contact face 22 to abut against a top surface 24 of the visible side workpiece 16 . The rivet head 20 is joined to a rivet shank 26 which may be inserted into a workpiece hole 28 in the workpiece arrangement. The rivet body 12 is penetrated by an axially continuous rivet hole 30 .

[0062] The mandrel 14 includes a mandrel head 32 realized for abutting against an end surface 34 of the rivet shank 26 . Furthermore, the mandrel 14...

Abstract

Blind rivet arrangement (10) for producing a blind rivet joint (64), said blind rivet arrangement having a rivet body (12) and having a mandrel (14), wherein the rivet body (12) comprises a rivet head (20), a rivet shank (26) and a continuous rivet bore (30), wherein the mandrel (14) comprises a mandrel head (32) and a mandrel shank (36) which is inserted in the rivet bore, wherein the rivet bore (30) comprises a first bore cross section (D1) in the region of an end of the rivet shank (26) which is opposite the rivet head (20), wherein the mandrel shank(36) comprises a first shank cross section (D2) in a first mandrel region (B1) adjacent to the mandrel head (32), and wherein the first shank cross section (D2) is adapted to the first bore cross section (D1). In this case, in a second mandrel region (B2) which projects out of the rivet bore (30), the mandrel shank (36) comprises a second shank cross section (D3) which is smaller than the first shank cross section (D2).

Description

technical field [0001] The present invention relates to a blind rivet device for forming blind rivet joints, said blind rivet device having a rivet body and having a mandrel, wherein said rivet body comprises a rivet head, a rivet shaft and a continuous rivet hole, wherein said the mandrel comprises a mandrel head and a mandrel shaft inserted into the rivet hole, wherein the rivet hole comprises a first hole section in the region of the end of the rivet shank opposite the rivet head, and wherein The mandrel rod includes a first rod section in a first mandrel region adjacent the mandrel head. [0002] Furthermore, the invention relates to a blind rivet joint having at least two workpieces and having a shaped blind rivet arrangement of the type described above. Background technique [0003] A blind rivet device of this type is known from document WO 2009 / 098431 A1 and is used for joining workpieces, with access only possible from one side (visible side). In this case, the bl...
