an axial distance of the axial forming rollers can be increased to each other, so that a final shaping takes place substantially through the forming groove of the compression roller.
the forming rollers may have radially projecting shoulders, which serve as a stop or stop edge to form approximately a radial inner or underside of the edge contour.
the two axial forming rollers are radially adjusted during the upsetting.
an adaptation to a gradual reduction of the diameter of the tube during upsetting can take place.
the axial forming rollers are spaced from the thickened region and the thickened region is finally shaped to the edge contour by the at least one compression roller.
the forming groove is formed in the compression roller according to the edge contour of the blank to be formed.
a particularly efficient variant of the method according to an embodiment of the invention is that in the same clamping of the blank, an outer edge with the molded-on thickened edge contour is transferred to a spinning tool and a circumferential wall region is formed.
the blank is clamped between the spinning tool and a counterholder.
an edge thickening is carried out, in which case the thickened region of the circular blank is subsequently transferred to the spinning lining in the same clamping operation.
a cylindrical or cup-shaped workpiece with an inner contour can preferably be produced without cutting in accordance with the outer contour of the spinning tool.
the transfer be carried out by means of at least one compression roller.
the compression roller has a multiple function. This multifunctional upset roller reduces the number of necessary pressure rollers and tools.
the compression roll according to the invention is characterized in that in addition a radially projecting pressure region is provided, which is designed for pressing and / or for pressure-rolling.
the compression roller can thus fulfill a dual function. It is used for radial compression with radial force application and for transferring the radial edge region of the Ronde axially on the spinning chuck, wherein substantially axial forces are applied.
the compression roller is thus formed with a pivot bearing which receives both radial and axial forces.
a preferred embodiment of the compression roller according to the invention is that the compression area are arranged in an axial center portion and the pressing portion in a lateral edge portion of the roller body.
the pressing region is radially projecting and has a pressing radius.
the pressing region it is particularly advantageous for the pressing region to have, in cross-section, a radially projecting nose with a pressing radius and an inlet and / or outlet slope.
the inlet bevel can in particular be designed so that a folding of the radially directed Ronde section is effected by an axial movement of the compression roller.
the inventive device for producing a forming part from a blank is characterized in that the above-described compression roller is provided.
