Abstract (en)
[origin: ES8501262A1] A method and apparatus for bending tubular workpieces whereby a tube length is placed in front of a template and selectively driven deforming shoes urge the tube into engagement with the same. Where the desired tubular radii of curvature are relatively large the deforming shoes are driven from a stationary mount. Where shorter tubular radii are desired, generally near the tube ends, the deforming shoes are arranged such that they are incrementally translated along a path commensurable with the contour of the template. At each successive increment the deforming shoes perform a bending operation upon the tube such that it may be successively formed into its desired shape.

Die Rohbiegeanlage umfaßt eine auf einer Grundplatte (10) verankerte Schablone (12), vor der das Rohr (14) liegt. Mittels Druckstempeln (40) wird das Rohr (14) an die Schablone (12) angeschmiegt, von der Mitte zu den Rohrenden hin fortschreitend. Vorzugsweise ist die Schablone (12) zum Ausgleich von Toleranzen verstellbar.
