Abstract
In order to reliably ensure a press-in connection between joining elements, in particular a press-in nut and a pre-punched component, a press-in device contains a die which has a die ring and a die mandrel. The die mandrel is mounted counter to a spring force in the manner of a pilot pin. In addition, the die ring is also mounted counter to a spring force such that a two-stage press-in operation is carried out. Preferably, during a first press-in stage an anti-rotation lock is formed between the press-in nut and the component and in a second press-in stage an axial pull-out prevention measure is formed. To this end, the die mandrel deforms a nut flange.
