Abstract:
The interior-forming tool for remodeling a sheet metal (2) to a tube, comprises two symmetrically rotatable rollers (4, 5) arranged around rotating axes, unit (11) for the synchronization of the rollers, a stem connected with a holder of the rollers by the synchronization unit, which is formed as tooth segments combing together, a moving element arranged between a carrier element (3) and the holder, an inset element for holding, and an adjustable element formed as a screw-nut-element. The rotating axes are formed directly in the rollers. The interior-forming tool for remodeling a sheet metal (2) to a tube, comprises two symmetrically rotatable rollers (4, 5) arranged around rotating axes, unit (11) for the synchronization of the rollers, a stem connected with a holder of the rollers by the synchronization unit, which is formed as tooth segments combing together, a moving element arranged between a carrier element (3) and the holder, an inset element for holding, and an adjustable element formed as a screw-nut-element. The rotating axes are formed directly in the rollers, which run on one side of the sheet metal and which are arranged symmetrical to a middle plain of the joint carrier elements. The moving element rotates around the rotating axes. A non-rotatable middle roller (6) is arranged alternatively in a direction lying in the middle plain of the carrier elements.
