摘要： The invention relates to a separating device (4) for the self-supporting bodywork (2) of a motor vehicle, comprising a separation disposed on the front end of a rear area (6), extending in a transversal direction of said motor vehicle and over part of the height between the wheel housings (8) of the vehicle and being secured to defining walls of the rear area. The separating device (4) is embodied as a support device which strengthens the bodywork (2) with respect to buckling. The invention is characterized in that the separating device (4) is curved in relation to a vertical motor vehicle cross plane (SFQ) and a horizontal motor vehicle cross plane (WFQ). The separating device (4) has reinforcing elements (10) with a higher material thickness along the power flow lines.

摘要： The invention relates to a method and a tool for producing structural parts from sheet metal which have a vault-structured reinforcement zone (4) and adjacent, flat connecting zones (8, 9). Starting material for producing said structural parts are vault-structured blanks (1) that are smoothed during shaping in the area of the connecting zones (8, 9) while the vault-structured structure remains unchanged in the area of the reinforcement zone (4). According to the invention, the structural parts are produced using an embossing die (14) that comprises a matrix (16) and a two-part die (15) which consists of a fixing die (26) and a shaping die (27). The blank is first fixed in the area of the vault-structured reinforcement zone (4) vis-à-vis the fixing die (26) by a fixing element (18) that advances the matrix (16). The connecting zones (8, 9) are then drawn between the matrix (16) and the shaping die (27).
