  • Patent number: 10870145
    Abstract: A device for attaching a joining element to a component section, which device is for a tool for attaching the joining element to the component section, wherein the joining element is adapted to be temporarily placed in a holding position and then shifted out of the holding position onto the component section by a linearly movable punch of the tool, wherein the joining element is temporarily placed in the holding position by means for providing a pressure difference in a region of the holding position, wherein the pressure difference on the temporarily placed joining element provides a holding force that acts on the joining element, so that the joining element is held positionally fixed in the holding position.

  • Patent number: 10307815
    Abstract: An apparatus for attaching a joining element or functional element to a component section, wherein the apparatus is provided for a tool for attaching a joining element or functional element to a component section with a punch which is movable forward in a linear manner and is movable back again, wherein, during its forward movement, the punch entrains a joining element or functional element out of the presentation position on the apparatus and slides it into a guide line of the apparatus. According to the present invention, at least two positioning strips are present which extend along the guide line, wherein the at least two positioning strips reach into the region of the presentation position such that the positioning strips are present laterally next to a joining element or functional element which is situated in the presentation position.

  • Patent number: 8978220
    Abstract: A die for a riveting tool for implementing a punch rivet connection between at least two joined part sections is proposed, the die being used in a state provided in the riveting tool for supporting the joined part sections during a connection procedure and a die front side facing toward a movable punch of the riveting tool, using which a rivet element can be pressed in a punching manner through the joined part sections to be connected, an embossing section of the die protruding in relation to adjacent areas of the die front side and causing an embossment in the die-side joined part section, so that components of the joined part material flow into an external depression on the rivet element. According to the invention, the embossing section is implemented as divided into sections. The invention additionally relates to a riveting tool.
