Device and method for pressing a plastically deformable blank

A method for pressing a plastically deformable blank into a three-dimensional section with a predetermined cross-sectional area, comprising pressing the blank past at least one rotary die having one or more recesses in its peripheral surface, so that the blank is formed by the rotation of the die, thereby determining the final shape of the three-dimensional section, wherein

• the blank is caused to pass an opening immediately upstream of the rotary die, whereby the blank, when passing through the opening, is substantially reduced down to the predetermined cross-sectional area.

A device for continuously pressing of a plastically deformable blank into a three-dimensional section with a predetermined cross-sectional area, comprising

• a fixed die with an opening formed therein, through which the plastically deformable blank is intended to be pressed, and
• at least one rotary die arranged immediately downstream of the opening and having one or more recesses in its peripheral surface for forming the blank into a three-dimensional section with transverse sectional parts during the rotation of the die, wherein:
• the rotary die is located within a cavity formed in the fixed die.

A method for pressing a plastically deformable blank into a three-dimensional section with a predetermined cross-sectional area, comprising pressing the blank through an opening in a fixed die past at least one die rotatably arranged around an axis extending transversely of the pressing direction and having one or more recesses in its peripheral surface, so that the blank is formed by the rotation of the die, thereby determining the final shape of the three-dimensional section, the rotary die being located within a cavity formed in the fixed die.
