摘要： The present invention aims with respect to a negative-angle forming die with a lower die half supporting a rotary cam and an upper die half having an intrusion forming portion cooperating with an intrusion forming portion of the rotary cam upon a descend of the upper die half to form a sheet metal product to avoid the problem that the work (W) is damaged by interference of the rotary cam (5) with portions of the work (W) protruding in a direction extending across the rotation axis during retraction of the rotary cam (5) after the intrusion forming. The rotary cam (5) is divided into at least an end rotary cam section (5 1 ) and a main rotary cam section (5 2 ), both of the divided rotary cam sections (5 1 , 5 2 ) being disposed on the same pivoting axis (L), and the end rotary cam section (5 1 ) being provided with means for restricting the end rotary cam section (5 1 ) from pivoting for a predetermined period of the pivoting during retraction of the rotary cam after the forming operation, and for axially moving the end rotary cam section (5 1 ) relative to the main rotary cam section (5 2 ) for a predetermined period of the pivoting during retraction of the rotary cam after the forming operation.

摘要： Bei einer Rotationsumformmaschine (1) wird die Relativbewegung zwischen einem Werkstück und ein oder zwei Walzen (3,4) so beeinflusst, dass an den Walzen (3, 4) vorhandene Stempel (8) an ausgewählten Punkten (P 0 ) eine Zykloidenbewegung durchführen, bei der der Flächeninhalt vorhandener Schleifen reduziert oder Schleifen ganz vermieden werden. Dadurch kann der Flankenverschleiß der Stempel (8) vermindert werden. Darüberhinaus kann die Qualität der erzeugten Werkstücke (11) verbessert werden. Ergänzend kann an der Flanke (34) des Stempels (8) eine Ausnehmung angeordnet sein, die das Schwenken des Stempels bei seiner Eintauchbewegung in das Werkstück (11) ohne erhöhten Flankendruck gestattet.

摘要： The present invention relates to a rotary punching device (1) for rotational machining of a material sheet (10). The rotary punching device (1) comprises a first shaft (20) rotationally activated by driving means (24), and a second shaft (30) arranged in parallel to the first shaft (20). The first shaft (20) and the second shaft (30) comprise a first tool (23) and a second tool (33) respectively. The rotary punching device (1) further comprises coupling means (40) configured for synchronizing rotation of the first shaft (20) and rotation of the second shaft (30) in an opposite direction.
The rotary punching device (1) further comprises displacement means (50) for displacing the first shaft (20) between an engagement position (51) and a disengagement position (52) relative to the second shaft (30). The first and second tools (23, 33) are configured for receiving and rotary punching the material sheet (10) when in the engagement position (51). The rotary punching device (1) further comprises a controller (60) controlling the displacement means (50) and/or the velocity of the first shaft (20) based on received positioning data (65) concerning the position of the material sheet (10).
