BENDING MACHINE AND BENDING METHOD

A bending machine (1) includes hydraulic cylinders (9L, 9R) capable of adjusting an inclination state showing an inclination to the left and right of an upper table (7), eccentric shaft units (19L, 19R) configured to curve a part of a lower table (5), and a control device (30). The control device (30) sets an inclination state of the upper table (7) and also sets a curved state of the lower table (5) to conform to the inclination state of the upper table (7) in order to carry out partial bending to pressurize a limited pressurized range compared to a pressurized range in which a workpiece (W) is pressurized by using entire areas of an upper tool (8) and a lower tool (6) in a lateral direction (X). The control device (30) changes a combination of the inclination state of the upper table (7) and the curved state of the lower table (5) and repeats the partial bending while causing a transition of the limited pressurized range in order to carry out entire area bending to pressurize the workpiece (W) over an entire area in the lateral direction (X).
