Publication number: 20240139855Abstract: An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.Type: ApplicationFiled: December 15, 2023Publication date: May 2, 2024Inventors: Dennis Schröder, Bernd Haesler, Kilian Doedtmann, Stefan Rehling, Sergej Hartwig-Biglau, Wilhelm Westermann, Oliver Schienstock

Patent number: 9149863Abstract: A setting device for connecting at least two components includes a first lever arm having a first working end, and a second lever arm having a second working end, that are pivotably connected to each other like pliers. A first linear drive is connected to the first and the second lever arm so that, by changing of the length of the linear drive, the first and second working ends can move relative to each other. A punch is arranged at a first working end that is connected to a supply module for joining elements, and/or a hold-down module.Type: GrantFiled: October 13, 2010Date of Patent: October 6, 2015Assignee: Bollhoff Verbindungstechnik GmbHInventors: Torsten Draht, Berthold Huhn, Bernd Haesler, Marion Keiser

Patent number: 8777080Abstract: The invention relates to a setting device for an auxiliary joining part, particularly a setting fastener or a punch rivet, including a driven punch which for a setting movement can be moved in a joining channel to which the auxiliary joining part can be loosely fed. The setting device includes a head piece in which a part of the joining channel runs, further including a plurality of compressed air ducts ending in the joining channel, and an exhaust air channel. The exhaust air channel ends adjacent to the front side of the punch moving the auxiliary joining part into the joining channel of the setting device such that an airflow can be generated in the joining channel in the direction of the front of the punch moving the auxiliary joining part by way of an overpressure which can be generated in the plurality of compressed air channels compared to the atmospheric pressure and by which the auxiliary joining part can be positioned on the front side of the punch.Type: GrantFiled: October 12, 2009Date of Patent: July 15, 2014Assignee: Böllhoff Verbindungstechnik GmbHInventors: Torsten Draht, Bernd Haesler, Carsten Löschner, Iris Spiller-Bohnenkamp, Marc Steinig
