    Abstract: The aim of the invention is to provide a method for controlling the flow of material when deep-drawing a workpiece, which better utilizes the drawing capacity of a workpiece and produces a better shape accuracy, particularly of the bottom of the drawn part. The aim is achieved by a method in which the deep-drawing process is performed incrementally and in which at least one bead is incorporated into the flange region of the workpiece prior to each increment of the deep-drawing process. Due to this, the shape accuracy of the bottom can be improved and material accumulations in the flange zone can be prevented.

    Abstract: A method and apparatus are disclosed which are suitable for use in the manufacture of two-piece metal containers. In particular, a way of making cups from metal sheet is disclosed using a combination of stretching and drawing operations. The resulting cups have the advantage of having a base thickness that is thinner relative to the ingoing gauge of the metal sheet.

    Abstract: A method and apparatus are disclosed which are suitable for use in the manufacture of two-piece metal containers. In particular, a press is disclosed which makes cup sections from metal sheet using a combination of drawing and stretching operations. The cups resulting from the press have the advantage of having a base thickness that is thinner relative to the ingoing gauge of the metal sheet.

    Abstract: In a method of making a sheet metal part for motor vehicles, a blank is placed with its opposite length sides between outer lower forming jaws of a die. The blank is then clamped by moving the outer lower forming jaws toward one another. Outer upper forming jaws are then moved to their closed position so that the length sides of the blank are secured in place between the lower and upper forming jaws. The lower and upper forming jaws and a press tool are then moved toward one another, and the blank is shaped to its final configuration to produce a sheet metal part.
