FIELD: metal forming.
SUBSTANCE: invention can be used for bending pipes, profiles or strips. The bending punch has a prefabricated structure and consists of plates such as a stop (1), an extension (2) and a flange (3), which have a round hole for fitting the bending punch onto the bending device shaft. The plates are interconnected by means of at least one threaded connection (4). Stops (1) are located with the possibility of placing a bent workpiece between them. The extensions (2) are located between the flange (3), which forms a stiffening rib on the workpiece, and stops (1).
EFFECT: reliability of the device is increased, its technological capabilities are expanded, and the quality of the products obtained is improved.
