Claims (1)

Patent-Ansprüche:Patent Claims: Walzen und verriegeln die Walzen in den Arbeitsstellungen. Durch eine aus zwei Hebeln und einer Verbindungsstange bestehende Bewegungsvorrichtung können die Walzen aus einer Arbeitsstellung in die andere gedreht werden. In -den einander zugekehrten Teilen der Walzen sind unter sich gleiche Aussparungen c, d, und e, f vorgesehen. Durch diese Aussparungen entstehen Biegekanten g, h, i, und k, I1 m. Die beiden Biegewerkzeuge, die einander völlig gleich sind, stehen in der Arbeitsstellung so, daß immer eine Biegekante einer Aussparung gegenübersteht, z. B. in Abb. 2 die obere Biegekante h der unteren Aussparung e und in Abb. 3 die untere Biegekante I der oberen Aussparung c. Bei der Stellung nach Abb. 2 wird das Werkstück also nach oben, nach Abb. 3 nach unten hohl gebogen. Hierdurch wird erreicht, daß das Werkstück, ohne daß es gewendet wird, lediglich durch Verdrehen der Biegewalzen, in beliebig abwechselnd nach oben und nach unten hohle Formen gebogen werden kann. Die Form und Zahl der Aussparungen sowie die Zahl der Arbeitsstellungen kann nach den jeweiligen Bedürfnissen verändert werden, so daß mit demselben Paar von Biegewerkzeugen ganz verschiedenartige Krümmungshalbmesser erzielt werden.Rollers and lock the rollers in the working positions. The rollers can be rotated from one working position to the other by means of a movement device consisting of two levers and a connecting rod. In the mutually facing parts of the rollers, the same recesses c, d, and e, f are provided. Bending edges g, h, i, and k, I 1 m are created by these recesses. B. in Fig. 2 the upper bending edge h of the lower recess e and in Fig. 3 the lower bending edge I of the upper recess c. In the position according to Fig. 2, the workpiece is bent upwards and downwards according to Fig. 3. This ensures that the workpiece, without being turned, can be bent into hollow shapes alternately upwards and downwards, simply by rotating the bending rollers. The shape and number of the recesses and the number of working positions can be changed according to the respective needs, so that very different types of curvature radius can be achieved with the same pair of bending tools.
