FIELD: process engineering. ^ SUBSTANCE: invention relates to metal forming, in particular to devices intended for free bending of lengthwise sections. Bending cylinder is arranged behind axial cylinder along feed direction. Feed unit and axial cylinder comprise one feed drive. Note here that axial cylinder can move independent of feed unit. Feed unit and axial cylinder incorporate also rotation drives for them to rotate in direction of section they retain and guide. Bending cylinder can be drive to reciprocate driven along only one axis passing across section lengthwise axis and feed direction, and rotate about axis crossing section lengthwise axis along feed direction. Besides bending cylinder can be drive to free driver with the direct cylinder or applying an it. ^ EFFECT: simplified design, expanded process performances. ^ 8 cl, 3 dwg |
