Abstract

A tool for pressing at least one auxiliary joining element together with a workpiece formed separately from the auxiliary joining element, includes two tool elements which can move towards one another along a movement direction and can thereby move out of an open position into a closed position, between which the workpiece and the auxiliary joining element can be arranged, such that the auxiliary joining element can be pressed together with the workpiece in a joining region of the workpiece by moving the tool elements into the closed position. At least one spring element is retained on the tool elements, and is elastically deformable along the movement direction and thereby transferable out of an initial state into a deformation state, and adopts the initial state in the open position of the tool elements. The workpiece can be supported at least in the open position on the spring element.
