Patent ID: 7275406

Claim:
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 a moving mechanism at an end, the articulated robot including: a first rotational mount rotatably attached to a base, 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.
