BENDING MACHINE WITH MOULD AND MALE MOULD FOR RIGHT-SIDE AND LEFT-SIDE BENDING OF EXTENDED DETAIL Russian patent published in 2015 - IPC B21D7/08 

FIELD: metallurgy.

SUBSTANCE: machine contains a roller mould (1; 31), which is driven by the motor shaft (0), and the first male mould (25) installed on the bearing element (19) rotated on the head (11) installed on the slide (8) which is implemented with a possibility of driving for movement of the first male mould (25) with reference to the roller mould (1; 31). Axes of the bearing element (19) and the head (11) are parallel. The roller mould (1; 31) is fitted with the holder (3, 4; 42) of the extended detail, and the second male mould (26) is installed on the bearing element (20) rotated on the head (11) along the axis parallel to the head axis (11) which is installed with a possibility of rotation by the lever (12) along the pre-set rotation arch around its axis, perpendicular to the slide (8). The machine is implemented with a possibility of selection of the first or second male mould (25, 26) for interaction with the roller mould (1; 31) at bending of the extended detail (P) depending on the required curvature of the right or the left bend.

EFFECT: possibility of change of bend direction without revolution of mould and male mould.
