FIELD: metallurgy.
SUBSTANCE: bending is carried out by one rotary die and blade-type plate punch performing the functions of abutment. The rotating punch is always located on the bisector of the bent blank inner angle and the second half-die and the free side of the sheet remain stationary. The bending mechanism for linear bending of sheet materials with a rotary pressure abutment comprises a composite die of two half-dies, one of which is fixed on the base, and the second one is simultaneously and consistently turned with the abutment by means of hinged fastening on the base. The device further comprises a dividing mechanism configured to provide rotation of abutment by the angle equal to half the rotation angle of the rotating half-die.
EFFECT: expanded technological capabilities.
