FIELD: metallurgy industry. ^ SUBSTANCE: invention refers to metal deformation process and can be used in bending machines. Machine consists of beam holder assembly (10) having C-shape in cross section and moved in two mutually orthogonal directions in relation to non-movable base and on which one or more bending beams are fixed. This machine consists of kinematic system for operating units drive, in which servo motors (15, 21, 22) and planetary reduction gears for moving beam holder assembly (10) are used. Besides in beam holder assembly (10) there used is connected mechanism consisting of two mechanical assemblies (13, 14) which form closed kinematic chain consisting of five elements connected by means of five kinematic turning pairs. ^ EFFECT: improving reliability. ^ 6 cl, 11 dwg |
