  • Method and embossing die for producing a body structural part from a vault-structured sheet metal
    Patent number: 7234336
    Abstract: A method and a tool are provided for producing structural parts from sheet metal which have a vault-structured stiffening zone and adjacent, flat connection zones. The starting point for producing these structural parts is vault-structured blanks which are smoothed in the region of the connection zones in the course of the forming, whereas the vault structure is retained unchanged in the region of the stiffening zone. These structural parts are produced by an embossing tool which has a die and a two-piece punch including of a fixing punch and a forming punch. In the process, the blank is first of all fixed relative to the fixing punch in the region of the vault-structured stiffening zone by a fixing element which is in a leading position with respect to the die. The connection zones are then shaped between the punch and the forming punch.
