Rolling tube forming produces complex forms with minimal tooling

Rolling tube forming machines from transfluid minimize the use of tools and allow for creation of freely formed geometries. The technology is most suitable for use on tubes that already have been axially preformed, if sharp-edged contours need to be created for sealing elements, or if perfect surfaces are required.

The servo-electric drive and CNC system allow the functions of different axes to be moved in an overlapping fashion. As all the setting parameters are stored, there are no complex adjustments. The forming process is possible both from outside to inside and from inside to outside. Completely different geometries can be formed with a single tool, a clamping jaw, and the rolling head, and lubricant use is reduced to a minimum.

If very demanding forming is necessary on high-strength materials, a closed rolling head is used. Highly complex geometries without space in the axial direction can be formed with three rollers that are included in an open structure. This allows the roller geometry to be carried out directly on a tube/flange connection. Roll threads and edge designs can be added with the same roller head and corresponding rollers, with or without forming, depending on requirements.
