PROBLEM TO BE SOLVED: To provide a bending machine capable of diversifying preliminary bend patterns at crowning, and excellently preventing reduction of bending accuracy.SOLUTION: The bending machine has an upper table (5) and a lower table (7) so that one of the tables goes up and down. On at least one side of the upper table (5) and the lower table (7), there are provided: a cylinder (31L) for bend correction, for generating pressing force (F) to press a surface (7a) on a side opposite to a table top (7t) so as to convexly bend the table top (7t) facing the other table; and a pressing direction change part (FB) for changing a pressing direction in which the pressing force (F) presses the opposite surface (7a). |
