Abstract: Two components are held in at least partially overlapping relation to each other between a hold-down device and an essentially flat lower tool and then are joined together by pressing an auxiliary joining element into one of the components a sufficient distance to plastically deform the components in a manner that positively joins the two components together. A tool with an optional wobbling movement and/or an optional variable force is used to press the auxiliary joining element into the first component. The magnitude of force applied by the hold-down device affects the direction of plastic flow of the material of the components in relation to the flat lower tool.

Abstract: Especially for increasing the process security and reliability of permanent connections between overlapping materials, a method is suggested for permanently joining overlapping plate-shaped parts, particularly metal sheets, by producing an undercut between the parts in a deforming manner, the method comprising the following steps: disposing the parts to be joined between a protrusion of a punch tool and a support area of a counter-tool, forming a temporary elevation on the side of the parts that faces the counter-tool, by pressing the punch protrusion into the parts to be joined against the support area at least until the parts rise from the support area outside the forming elevation, and forming an undercut in the parts by flattening the elevation between punch tool and counter-tool by the punch tool further approaching the counter-tool. Furthermore, a device is suggested for carrying out said method.

Abstract: The invention relates to a method and a device for joining at least two components, which overlap at least in part, in a mechanical joining process without prepunching and with the aid of a deformable auxiliary joining element, and to the auxiliary joining element itself; said auxiliary joining element is pressed into the components to be joined by an upper tool that is displaced against an essentially flat lower tool at least with an axial advancing movement, and these components are joined to one another under plastic deformation of said components as well as of said auxiliary joining element.
