Method for attaching fasteners to sheet metal car body parts uses matrix with movable shaping part to press sheet metal part into undercut section of fastener

摘要

The fastener (10) or other function element is pressed against the sheet metal part (12) supported by a matrix (14) and the sheet metal material (13) is pressed by a movable shaping part (16) of the matrix into an undercut section (18) of the fastener whereby at least one engagement section (20) of the shaping part is moved with a radial component perpendicular to a longitudinal axis (22) of the matrix in order to press the material into the undercut. Independent claims describe matrix with movable shaping part, function element such as fastener fixed fluid-tight and gas-tight on sheet metal part, and intermediate component part comprising sheet metal part and function element positively connected together.
