Device for attaching a joining element to a component section, and tool

A riveting tool for attaching a joining element to a component section, the riveting tool comprising:

• a linearly movable punch;
• a holding position;
• a wall section in the region of the holding position;
• and
• a bore having an outflow opening proximate the holding position;
• wherein the joining element is initially temporarily placed in the holding position by a pressure difference between a positive pressure from a positive pressure directed gas stream flowing in a region of the holding position on one lateral side of the joining element and a negative pressure from a negative pressure directed gas stream flowing in the region of the holding position on the opposite lateral side of the joining element;
• wherein the negative pressure directed gas stream is provided in the vicinity of the holding position via the outflow opening of the bore, which is in communication with a vacuum pump;
• wherein the pressure difference on the temporarily placed joining element exerts a holding force that acts on the joining element so that the joining element is held positionally fixed in the holding position;
• wherein the wall section receives and retains the joining element such that when the joining element initially reaches the holding position under the effect of the pressure difference, the joining element occupies the holding position in a positionally and orientationally desired manner, and the opposite lateral side of the joining element is pressed laterally against the wall section via the negative pressure directed gas stream applied on the opposite lateral side of the joining element;
• wherein the negative pressure directed gas stream is evacuated via the outflow opening in the bore, so that when the joining element is in the holding position, the outflow opening is closed off by the joining element;
• and
• wherein the joining element is shifted out of the holding position onto the component section by the linearly movable punch.
