Bending device

A bending device comprising:

• a chuck mechanism that grips a longitudinal workpiece;
• a bending mechanism that clamps the workpiece with a bending die and a clamping die capable of moving around the bending die, and that bends the workpiece by rotation of the clamping die;
• an articulated robot that is capable of pivoting and provided with the moving mechanism at an end,
• the articulated robot including
• a first rotational mount rotatably attached to the mount,
• a first arm rotatably connected to the first rotational mount at one end via a first swinging joint,
• a second arm connected to the other end of the first arm at one end via a second swinging joint,
• a second rotational mount rotatably connected to the other end of the second arm via a first pivoting joint,
• an end arm attached to the second rotational mount at one end via a third swinging joint, and
• a supplemental joint that is attached to the other end of the end arm and rotates the end arm to rotate the bending mechanism;
• and
• a control unit that controls the movement of the articulated robot and moves the bending mechanism along the workpiece.
