Abstract

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.

Description

technical field [0001] The invention relates to a self-piercing rivet die for setting self-piercing rivets on at least first and second parts, a mounting device combined with the self-piercing rivet die, through which the self-piercing rivet die is formed in at least two A connection established between components, and a method for establishing this connection. Background technique [0002] In the prior art it is known to join at least first and second parts by means of self-pierce riveting. For this purpose, the self-piercing rivet is driven by a mounting device to at least two parts, wherein the at least two parts are supported on a die arranged opposite the punch. Due to its shape, this mold affects the characteristics of the joint connection. [0003] For example, DE 199 05 528 B4 discloses an anvil mold which is characterized by a flat surface which serves as a seat for supporting the parts to be joined. The die formed in this manner provides an aesthetically appeali...
