Abstract: The present disclosure concerns devices and methods for resistance welding sandwich sheets to other components. Many sandwich sheets include a thermoplastic material layer disposed between two metallic cover layers. The sandwich sheet and the other component may be secured relative to one another by a clamping arrangement. A region of the sandwich sheet to be welded may be heated by a preheating current to soften and displace the thermoplastic material layer when the cover layers are pressed together. With respect to the preheating current, a first electrode arrangement may at least temporarily contact an electrically conductive contacting region of the clamping arrangement such that the preheating current can flow via the clamping arrangement. The cover layers may be welded to the other component with a welding current via the first welding electrode of the first electrode arrangement and a second welding electrode of a second electrode arrangement.

Abstract: A tool exchange assembly and related method configured to swap change tool assemblies with a nutrunner constructed in accordance to one example of the present disclosure includes a nest. The nest has a lower jaw portion and an upper jaw portion. The lower jaw portion has first and second lower fingers that cooperate to define a lower slot. The upper jaw portion has first and second upper fingers that cooperate to define an upper slot. The nest is configured to receive a change tool assembly. Relative movement of the change tool assembly and the nest urges a sleeve on the change tool assembly to move between a locked position and an unlocked position.

Abstract: The invention relates to a method for bending at least one edge of a composite sheet, which has at least two outer metallic layers and an inner plastic layer, in which the edge of the composite sheet is edge-bent in a first step and is bent into the finished form in at least one further method step. In addition, the invention relates to a correspondingly bent composite sheet. The object of making a method for bending a composite sheet available, in which cracks in the metallic layers of the composite sheet can be prevented and, at the same time, in which a seam can easily be provided, is achieved by using an edge-bending punch, a holding-down device and an edge-bending jaw during the edge-bending operation and by the edge-bending punch having a notch running in the bending direction below the bending edge of the edge-bending punch.

Abstract: A drive device for driving a tool slide in a folding installation is proposed, wherein the drive device comprises a slide plate connected directly or indirectly to the tool slide, and a driveshaft that is rotatable about a rotation axis, wherein a rotary movement of the driveshaft is convertible by means of a cam disk into a linear movement, extending in the feed direction, of the slide plate.

Abstract: A welding electrode unit may include a repositioning device that is movable. The repositioning device may include a stored-energy means by way of which a welding electrode connected directly or indirectly with the stored-energy means can have a force applied to it for the purpose of a repositioning movement. The repositioning device can be moved into a welding position by way of a forward movement and can be locked in the welding position.

Abstract: A method for testing a transmission, in particular a double clutch transmission, is provided. A torque is introduced into the transmission by means of a drive unit that is external relative to the transmission, and the transmission is switched to an operating state in which an internal component of the transmission functions as a brake in order to simulate an output unit.

Abstract: A device for stopping and/or aligning transport goods on a conveying device, in particular a roller conveyor, device has a main part and a stopping device that can be moved out of the main part into a conveying path of the conveying device in order to stop and/or align the transport goods that are transported along the conveying path. The stopping device comprises at least two separate stops that can be moved between a working position, which projects into the conveying plane, and a rest position, which is retracted with respect to the conveying plane, by means of a common actuator device.

Abstract: The invention relates to a door of a motor vehicle having an outer panel (1), an inner panel (2), a plate-shaped member (6), which is arranged on the door inside, for various add-on and mounting units, and reinforcement regions (14 to 17) for door functional elements and an installed stiffening member (3, 4) as a side-impact protector. In order to optimize the ratio of stiffness to side-impact protection of the door and to optimize the production expenditure of the door, the inner panel (2) and the stiffening member (3, 4) are formed as an integral frame-shaped component (5) which includes the reinforcement regions (14 to 17) from high-strength to superhigh strength steel sheet, and that are hot-worked. In order to be able to install the add-on and mounting units with sufficient mounting length, the plate-shaped member (6) is fastened to the inner panel (2) by means of a holding frame (7) which provides the desired mounting depth.

Abstract: A device (1) is provided for connecting a metal sheet (23, 33?) at the edges, particularly body sheet metal in automobiles. The device (1) includes at least one folding bed (2) for receiving at least two metal sheets, folding jaws (3) which are functionally connected to associated folding jaw supports (4), at least one thermal jointing tool (5), and at least one mass electrode (9, 9?). At least the joining tool is not attached to the folding jaws, and the joining tool contains a lever oriented away from the folding bed as a linear feed device. The lever (6) has a center of rotation (10) outside the folding bed, wherein the joining tool can swivel in the manner of a knee lever into an operating and/or non-operating position.
