A body for a motor vehicle and a method for producing a motor vehicle body is provided. Such a body comprises two roof frame longitudinal profiles (), at least one roof frame cross profile () arranged between the roof frame longitudinal profiles () and a body pillar (), wherein in a connecting area (Y) a roof frame longitudinal profile (), a roof frame cross profile () and the body pillar () are connected or can be connected together using a mechanical connection. Here the roof frame longitudinal profile () comprises a recess () in the connecting area (Y), as seen in a longitudinal section of the roof frame longitudinal profile (), the recess accommodating the roof frame cross profile (), at least some areas of the circumferential contour of the profile being adapted to match the recess (). At least parts of the mechanical connection of the roof frame cross profile () to the body pillar () are disposed in the recess () and are designed such that the two opposing side walls of the recess () are supported against each another.

Body for a motor vehicle and method for producing a motor vehicle body

A body of a motor vehicle includes a lateral roof region that has an outer skin, an outer roof frame, and an inner roof frame, wherein the outer roof frame is arranged under the outer skin and the inner roof frame is arranged under the outer roof frame, and the outer skin, the outer roof frame, and the inner roof frame have a common welded flange, by means of which the outer skin and the outer and inner roof frames are connected to one another, and which is configured to receive an adhesive layer for a roof module having a roof module frame. An aspect of the invention is to provide an accident-optimized vehicle body at little expense that prevents a tearing off of the roof module, and is achieved in that the outer roof frame of the body is configured as a locking element for the roof module frame.

Roof construction of a vehicle body

A method for controlling the material flow during the deep-drawing of sheet metal involves compressing the edges of the sheet metal () between at least one upper stopper () and at least one lower stopper () during the deep-drawing process, with a controllable elastic force (). A corresponding deep-drawing tool is also provided. A Z-shaped blocking step () is stamped into the edge () of the sheet metal when the upper and lower stoppers () are closed, the basic shape is then produced by deep-drawing, maintaining the blocking step () and completely blocking the sheet metal between the stoppers. The sheet metal () is outwardly stretched, and the blocking step () is then reduced in terms of height, facilitating the outward displacement of the sheet metal towards the outside. The deep-drawing tool has a lower stopper including an inner stopper () and an outer stopper (). The stoppers are arranged in an annular manner on the edge of the sheet metal () and can be displaced in relation to each other in the holding direction.
