Title:
RIVETED CONNECTION
Document Type and Number:
WIPO Patent Application WO/2012/146359
Kind Code:
A3
Abstract:
Riveted connection between a sheet metal part (1) having a through-hole (10) and a rivet (2) which comprises a factory head (21) resting against one side of the sheet metal part (1) and a contiguous shaft (22) which extends through the hole (10), one section of the shaft (22) projecting over the other side of the sheet metal part (1) and being deformed to a buck tail (23) by plastic cold-working, resulting in the sheet metal part (1) being arranged in a form-fit between the factory head (21) and the buck tail (23) of the rivet (2). In order for the riveted connection to withstand high static forces and high dynamic loads reliably and permanently and to be producible with comparatively large tolerances of thickness of the sheet metal part (1), the dimensions of the rivet (2) and the shaping of the buck tail (23), the thickness of the sheet metal part (1) in the region of the buck tail-side edge (12) of the hole (10) is multiplied by two by folding over the buck tail-side edge (12).
