  • Patent number: 12290872
    Abstract: 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.

  • Patent number: 12030144
    Abstract: A bolt setting method and device for a nail-shaped bolt with a head and a shaft, ending in a tapered manner. The bolt setting method includes: joining the bolt into a component with a deforming stroke during which the bolt reaches a first joining speed of ?4 m/s and the shaft completely penetrates the components with a portion of a maximum diameter with respect to a shaft length, without a bottom side of the head abutting the at least one component, and after the deforming stroke, driving the bolt into the at least one component until a head abutment of the bottom side of the head on the at least one component by at least one friction stroke with which a frictional connection between the shaft and the components is overcome and with which the bolt reaches a second joining speed that is smaller than the first joining speed.
