Device for free forming of longitudinal profiles, particularly pipes, and a combined device for free forming and bending as well as draw-bending longitudinal profiles, particularly pipes

摘要

The present invention relates to a device for free forming and bending of longitudinal profiles (1), in particular tubes, in the case of a feed unit (2) in the direction of advance of an axial sleeve (3) is arranged downstream of. The axial sleeve (3) in the direction of advance is a spiral sleeve (4) is arranged downstream. The feed unit (2) and the axial sleeve (3) each have a pointing in the direction of advance drive, whereby the axial sleeve (3) independently of the feed unit (2) is adjustable. Furthermore, the feed unit (2) and the axial sleeve (3) of the rotary drives for the same direction and with simultaneous rotation of the longitudinal beam which are guided and held by them to. The bending sleeve is only in a direction transverse to the axis of the longitudinal beam and the feed direction extending axis in a translatory manner can be adjusted by means of a drive. In addition, it can, by means of a drive about a transverse to the axis of the longitudinal beam and the feed direction axis are pivoted. The bending sleeve (4) is also freely rotate together with the guide sleeve or opposite to it, mounted in a braked.
