Abstract

See full text

The present invention relates to a method for the punching in and attachment of the fastener element to a planar workpiece, in particular to a sheet metal part. During the punching in of the fastener element in the workpiece a movably arranged die plunger of the die button is pressed with a predetermined pressing force against the workpiece. The pressing force is adapted such that the die plunger first moves once a slug has been cut out of the workpiece by a piercing section of the fastener element.
