Abstract

Zum Profilkneten von strangförmigen Werkstücken (2)(Halbzeugen), die entlang einer Zentral-Achse (1) in eine Bearbeitungsstation (Profilknetmaschine) transportiert werden, werden wenigstens zwei sich paarweise gegenüberliegende Gesenke (4) zur Oberflächenbearbeitung des Werkstücks (2) auf ihrer der Achse abgewandten Seite von Stößeln (5) beaufschlagt; die Stößel (5) werden durch auf einer Kreisbahn relativ zu äußeren Führungsflächen der Stößel (5) bewegte Rollen (7)(Walzen,Kugeln) in radialer Richtung zur Achse angestoßen; dabei werden wenigstens zwei Gesenkpaare, deren radiale Stoßrichtung um einen vorgegebenen Winkel (90°) auf der Achse gegeneinander verschoben sind, mittels der Führungsflächen der Stößel (5) zeitlich aufeinanderfolgend von den Rollen (7) in radialer Richtung angestoßen; die Kantenlänge der Gesenke (4) ist bei jedem Arbeitsschritt größer als die angestrebte Kantenlänge des zu bearbeiten Werkstücks (2)(Halbzeugs).For profile kneading of strand-shaped workpieces (2) (semi-finished products) that run along a central axis (1) are transported to a processing station (profile kneading machine), at least two opposing dies (4) in pairs for surface processing of the workpiece (2) on their side facing away from the axis by tappets (5); the plunger (5) by rollers (7) (rollers, balls) which are moved on a circular path relative to outer guide surfaces of the tappets (5) triggered in a radial direction to the axis; at least two pairs of dies, their radial direction of impact against each other by a predetermined angle (90 °) on the axis are shifted in time by means of the guide surfaces of the plunger (5) pushed by the rollers (7) in the radial direction; the edge length of the dies (4) is for everyone Work step greater than the desired edge length of the workpiece (2) to be machined (semi-finished product).
