Abstract:
The invention relates to a method for producing a riveted connection between a ball joint pin, having a pin longitudinal axis (BLA), and a component in the form of a metal sheet with an abutting portion surrounding a preliminary hole, in which the ball joint pin has at least one ball head portion an adjoining shank portion, a planar plate portion, having an upper side and an underside, and a rivet flange portion, in which the ball joint pin is connected to the component by deforming the rivet flange portion. Advantageously, in a first step, the ball joint pin is inserted into the preliminary hole by means of an inserting tool in such a way that the plate portion is supported at least in certain portions by its underside on the abutting portion of the component in the form of a metal sheet, preferably with surface-area contact. In a second step, the rivet flange portion, which at least in certain portions is in the form of a hollow cylinder, is subsequently deformed in a controlled manner in the direction of the component in the form of a metal sheet by of a forming tool in the form of a die, in particular a riveting punch, to produce the riveted connection.
