PROBLEM TO BE SOLVED: To provide a bending machine with a mechanism for adjusting the length of a bending die with which both ends are rounded even when changing the length of a bending die group variously and a bending piece can be worked so that the corner portion of an opening part has a rounded corner portion. SOLUTION: The mechanism 2 for adjusting the length of the bending die has a traveling body 21 on which the bending die group 3A is placed and which is moved in and out in the line-up direction of the bending dies to/from the bending machine body 1. The traveling body 21 has a pair of abutting members 22, 23 on which both ends of the bending die group 3A are abutted. An abutting member moving mechanism 24 for moving an abutting member 23 on one side in the direction of the line-up direction of the bending dies with respect to the traveling body 21 is provided. A bending die storage mount 25 for arranging surplus bending dies 3 to the bending die group 3A in a line along the traveling route of the traveling body 21 and placing them is provided. An unloading pusher mechanism 26 for pushing out the bending die 3 on the traveling body 21 onto the bending die storage mount 25 is provided. A placing pusher mechanism 27 for placing the arbitrary number of bending dies 3 on the bending die storage mount 25 onto the traveling body 21 is provided. COPYRIGHT: (C)2008,JPO&INPIT
