A method for stretch-bend of an elongated profiled structure and the stretch-bend leveler for carrying out the method

摘要

A method for stretch-bend of an elongated profiled structure (1) which at the two profile component ends (14, 15) by means of clamping elements (33, 34) and has a main bending moment (11) around a bending tool (12) is bent, wherein during the bending process, in addition, an axial tensile force on the profiled component (1) is applied for a the stresses produced by the bending process, which is superimposed on the addition of tensile stress (5), characterized in that, in addition, at at least one profile component end of an addition bending moment (10) in the direction opposite to the main bending moment (11) is applied.
