A method for connecting of a sandwich sheet with a metallic component and part of the vehicle body as an external sheet metal plate and with a composed of a metallic component

摘要

The invention relates to a method for connecting a plastically deformable sandwich sheet (1), the two metallic cover sheets (1.1, 1.3) which, by an electrically insulating or electrically poorly conductive intermediate layer (1.3) are connected to a metallic component (2), in particular sheet metal, in which the composed of (1) is folded at one end section and an end section of the metallic component (2) is folded in the fold, characterized in that the edge of the item to be folded end portion of the sandwich sheet (1) in front of the folding or during the seaming is trimmed in such a way that the cut edge (1.11) of the cover plate (1.1) which, after the folding operation is arranged on the outside, with respect to the cutting edge (1.21) of the second sheet metal cover (1.2), which, after the folding operation on the inside on the metallic component (2), a measure, the at least 75% of the thickness (d) of the intermediate layer (1.3) of the sandwich sheet, and in that upon folding of the projecting cutting edge (1.11) of the externally arranged cover plate (1.1) on the metallic component (2) is pressed. In addition, a part of the body, in particular a door for a vehicle, the / which a composed of (1) as an external sheet metal plate and a metallic component (2), in particular an internal sheet metal plate has, wherein the composed of (1) at an end section folded, and at least one end section of the metallic component (2) is folded in the fold, characterized in that the edge of the sandwich sheet (1) is trimmed in such a way that the cut edge (1.11) of the outer cover plate (1.1) with respect to the cutting edge (1.21) of the inner sheet metal cover (1.2), the at least 75% of the thickness (d) of the intermediate layer (1.3) of the sandwich sheet, and in that the projecting cutting edge (1.11) of the outer cover plate (1.1) in the direction of the metallic component (2) is curved and rests in an electrically conductive manner at the same.
