发明名称 STRUCTURAL OR CHASSIS COMPONENT FOR A MOTOR VEHICLE, AND METHOD OF MAKING SUCH A STRUCTURAL OR CHASSIS COMPONENT
摘要 In a method of making a structural or chassis component for a motor vehicle, a blank is provided with at least one material supply in an outer region at a distance to the outer edge to serve as material reserve. The blank is placed in a press tool for shaping the blank into a structural or chassis component by displacing the material supply in a direction of the outer edge and pressing the outer region of the blank against a buttress of the press tool to thereby form the outer region in a recess of the press tool to produce bead.
