Claims

1. Rolling die press, in which a supply to the press axis takes place, the press axis having a cone or the central axis of the die press inclined 5 describes a tip angle of about 3 to 10 ° arranged male carrier is provided, as a result of which the tool surface rotates opposite a spherical cap is supported and hydraulic over the workpiece surface and touches it in one against the workpiece in the die limited area, so that the deformation is pressed, the line of contact of the male part of the workpiece causing total pressure and the workpiece is set at the intersection of the center. Because the tool is at work and the patrix support axis begins, furthermore the piece over one of the radius of the to be deformed peg-shaped patrix carrier end rests in a workpiece of the same length, a driven, to the central axis of the roll die displacement of the material under the pressure of the male mold press eccentric ring is mounted, thereby in the longitudinal direction. Such a shift without self-rotation, the patrix carrier axis on 15 is not always an advantage, since sometimes the common cone surface is guided, resulting in the desired shape only through radial displacement of indicates that the eccentric ring material surfaces in the workpiece are reached (6) in another can also be driven. However, such radial movement is at eccentric ring (7) is arranged. the known presses due to the friction between

Rolling die press, in which a 20 to press the workpiece and tool surfaces difficult, axis or central axis of the die press from German patent 542 949 it is inclined male carrier is provided, but known, the previously purely tangential direction which is supported by a spherical cap and hydraulic material displacement through superimposition with lisch against the workpiece in the die to improve radial components. This achieved is pressed, whereby the line of contact of the patrix »5 has hitherto been done by touching the tool and imparted to the workpiece at the intersection of the medial and radial movements.
