The disclosure further relates to a corresponding self-piercing rivet joint, to a method for producing the self-piercing rivet, and to a method for producing the self-piercing rivet joint.

Semi-tubular self-piercing rivet for thin sheet metal joints, method for producing said semi-tubular self-piercing rivet, and method for producing a joint

A self-piercing riveting die for a setting device, by which a self-piercing riveting connection in a plurality of components is establishable by forming a closing head. This self-piercing riveting die may include a main body with an upper side and a recess arranged rotationally symmetrically to the central axis of the self-piercing riveting die formed therein. In the cross-section of the self-piercing riveting die, the recess has a demolding inclination of the demolding section, which radially transitions via a step into a circular arc-shaped lowering of the annular channel section, wherein the circular arc-shaped lowering radially inwardly rises straight-lined or circular arc-shaped or curvilinearally to the die bottom.
