EMI2.1 Dreiteiliges Schmiedepressengesenk zur Herstellung gratloser Schmiedestücke in einem Arbeitsgange, dadurch gekennzeichnet, dass das Pressgut, welches in die vom festen Press EMI2.2 eingebracht ist, von dem niedergehenden Oberstempel (a) so weit zusammengepresst wird, dass das überschüssige Material zwischen dem festen Pressring (b) und dem niedergehenden Oberstempel (a) als Grat oder Strang hervorquillt, dass darauf der Oberstempel nach Senken oder unter gleichzeitigem Senken des Unterstempels weiter niedergeht und das Werkstück abwärts drückt, so dass der an ihm haftende Grat oder Strang von der Ober- kante des Pressringes abgeschert wird. EMI2.3 EMI2.1 Three-part forging press die for the production of burr-free forgings in one operation, characterized in that the pressed material, which is in the from the fixed press EMI2.2 is introduced, is pressed together by the descending upper punch (a) so far that the excess material between the fixed press ring (b) and the descending Upper punch (a) swells out as a ridge or strand, so that after lowering or at the same time lowering the lower ram, the upper ram goes down further and presses the workpiece downwards so that the ridge or strand adhering to it is sheared off the upper edge of the press ring.
