Abstract

The computer controlled (14), CNC, machine has a carriage (12) that moves linearly on guide bars. Mounted on the carriage is a controlled bending tool (5) that rotates. One end of a tube is clamped (7) to the carriage and the other clamped to the frame (8). The slide and bending tool are hydraulically powered and controlled by electro hydraulic valves (15,16).

Claims (4)

1. Vorrichtung zum Biegen von Rohren und Profilen, dadurch gekennzeichnet, dass die Vorrichtung Mittel enthält mit denen in der Biegezone entstehende Spannungen durch geometrische Kopplung einer rotatorischen an eine schlupffrei angekoppelte translatorische Bewegung und die daraus resultierende Verschiebung der neutralen Faser in definierter Form kompensiert werden können.1. Device for bending pipes and profiles, characterized in that the device contains means with which the stresses arising in the bending zone can be compensated in a defined form by geometrically coupling a rotary translatory movement coupled to a slip-free movement and the resulting displacement of the neutral fiber , 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die schlupffreie geometrische Kopplung der rotatorischen mit der translatorischen Bewegung dadurch erfolgt, dass die Bewegung über Achsenantriebe gesteuert werden, deren Regelgrößen von einer CNC-Steuerung in Auswertung der Biegewinkel- und Weginformationen errechnet werden.2. Device according to claim 1, characterized in that the slip-free geometric coupling of the rotary with the translatory Movement takes place in that the movement is controlled via axis drives whose control variables are evaluated by a CNC control system Bending angle and path information can be calculated. 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass ein Biegekopf (5) mit einem linear angeordneten Schlitten (12) verbunden ist und der Linearantrieb gleichzeitig noch die Führung des Systems übernimmt.3. Device according to claim 1 or 2, characterized in that a bending head ( 5 ) is connected to a linearly arranged slide ( 12 ) and the linear drive simultaneously takes over the management of the system. 4. Vorrichtung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die Abstützung der translatorischen Kräfte gegenüber dem Werkstück gleichzeitig den Ursprung des Messsystems für die translatorische Bewegung bildet und äußere Einflüsse auf das Messergebnis, wie zum Beispiel Gestell- und Werkstückverformungen, weitestgehend ausschließen.4. Device according to one of the preceding claims, characterized characterized in that the support of the translational forces the origin of the measuring system for the workpiece forms translatory movement and external influences on the measurement result, such as frame and workpiece deformation, as far as possible exclude.
