Abstract
Die Erfindung betrifft ein Werkzeug (1) zur Verformung rotationssymmetrischer ringförmiger Körper (17), welches eine Mehrzahl Pressbacken (3, 4) aufweist. Zur Vermeidung axialen Verrutschens weisen mindestens drei Pressbacken (4) axiale Führungsvorrichtungen (9) auf. Führungsstücke (14) ragen um den Betrag der Dicke (18) eines zu verformenden Ringmateriales (17) vor den radial am weitesten nach innen ragenden Punkt der jeweiligen Pressbacke (4) vor und sind federnd gelagert, so dass die vorspringenden Teile der Führungsstücke (14) bei Kontakt mit durch die Spannringe (17) zu verspannenden weiteren Teilen relativ zu den Pressstücken (4) radial nach außen verschiebbar sind. Diese Anordnung hat den Vorteil, dass die ringförmigen Körper (17) während des gesamten Umformvorganges axial geführt sind. Die federnde Lagerung verhindert Beschädigungen an den zu bearbeitenden Werkstücken. The invention relates to a tool (1) for deforming rotationally symmetrical annular bodies (17), which has a plurality of pressing jaws (3, 4). To avoid axial slipping, at least three pressing jaws (4) have axial guiding devices (9). Guide pieces (14) protrude by the amount of the thickness (18) of a ring material (17) to be deformed in front of the radially inwardly projecting point of the respective pressing jaw (4) and are resiliently mounted, so that the projecting parts of the guide pieces (14 ) are in contact with by the clamping rings (17) to be clamped further parts relative to the pressing pieces (4) radially outwardly displaceable. This arrangement has the advantage that the annular body (17) are guided axially during the entire forming process. The resilient mounting prevents damage to the workpieces to be machined.
