Abstract:
1. A die for a riveting tool for implementing a punch rivet connection between at least two joined part sections, the die comprising: a stationary die main body that, when provided in the riveting tool, supports the joined part sections during a connection procedure, the die main body having a die front side facing toward a movable punch of the riveting tool, with which a rivet element can be pressed in a punching manner through the joined part sections to be connected; and an embossing section arranged radially inwardly from adjacent areas of the die front side, wherein the embossing section is movable within the die main body between a retracted position and a protruded position where a portion of the embossing section protrudes upwardly in relation to the adjacent areas of the die front side, wherein, when in the protruded position during the connection procedure, the outer surface of the embossing section directly contacts an inner surface of the die main body and causes an embossment in the die-side joined part section, so that components of the joined part material flow into an external depression on the rivet element, and wherein the embossing section is implemented as divided into sections that define an axial hole extending through the center of the embossing section to receive slugs that are removed from the at least two joined part sections through action of the rivet element.
