Abstract
A method of attaching a functional element (10, 210), in particular a fastener element to a sheet metal part (12, 212), optionally in liquid and/or gas-tight manner, is characterized in that the functional element (10, 210, 410) is pressed against the sheet metal part (12, 210, 410) supported by a die (14, 114, 214, 414) and sheet metal material (13) is pressed by means of at least one movably mounted shaped part (16, 116, 216, 416) of the die (14, 114, 214, 414) into an undercut (18, 218, 418) of the functional element (10, 210, 410). The disclosure also claims a die, a functional element, and a component assembly comprising the functional element and a sheet metal part.
Claims29
A die (14, 114, 214, 414) having a longitudinal axis and an approximately pot-like forming space (30, 130, 230, 430) into which a head part (10a, 210a, 410a) of a functional element (10, 210, 410) can be introduced for the reshaping of a sheet metal part (12, 212, 412) placed between said die and said functional element, said die having at least one movably mounted shaped part (16, 116, 216, 416) which bounds said forming space (30, 130, 230, 430) at least regionally, wherein the shaped part or parts is or are formed for the pressing of material (13) of said sheet metal part into an undercut (18, 218, 418) of said functional element (10, 210, 410) by a movement towards the longitudinal axis of the die during a closing movement of said at least one movably mounted shaped part.
