Abstract

The invention relates to a tool for applying punched rivets, either full rivets or semi-tubular rivets. The tool having a blank holder for pretensioning assembly pieces, especially metal sheets; a rivet punch movable in an axial direction within a cylinder of the blank holder; and a die that is arranged opposite the blank holder and punch and provided with an annular prominence on an end face thereof and facing the rivet punch. A radial outside section of said end face concentrically surrounds said annular prominence, the outside section of said end face being displaceable relative to the annular prominence as a function of one of the penetration depth of the rivet into the assembly pieces and the force that the rivet punch exerts on the rivet.
