FIELD: production of products from rolled sheets.

SUBSTANCE: bending machine contains a frame with a table for installing the workpiece, a mechanism for fixing the workpiece, and a bending mechanism placed on it. The fixing mechanism includes a clamp installed with the possibility of reciprocating movement in a plane perpendicular to the plane of the bends. Bending tools are made in the form of rollers placed on bending arms. One end of each lever is hinged on the machine table, and the second end is connected to the pneumatic cylinder rod.
