| 20120016512 | BENDING DEVICE - A bending device that bends a workpiece is provided with a bending mechanism that bends the workpiece, a fixing table on which a chuck mechanism that grips the workpiece is mounted, an articulated robot to which the bending mechanism is attached, and a control unit that controls operations of the bending mechanism, the chuck mechanism, and the articulated robot. The control unit includes a first control unit that twists the bending mechanism around a longitudinal axis of the workpiece, and a second control unit that controls the articulated robot to twist the bending mechanism holding the workpiece around the longitudinal axis of the workpiece within a twisting angle range and then causes the first control unit to perform the twisting. | 01-19-2012 |
| 20120016511 | BENDING DEVICE - A chuck mechanism that grips a workpiece is configured to be able to twist and rotate the gripped workpiece around a longitudinal axis of the workpiece. A control unit is provided with a first control unit and a second control unit. The first control unit drives an articulated robot to which a bending mechanism for bending the workpiece is attached, and twists the workpiece clamped by the bending mechanism around the longitudinal axis of the workpiece within a preset twisting angle range. When the angle of twisting by the first control unit exceeds the twisting angle range, the second control unit controls the chuck mechanism to twist the workpiece around the longitudinal axis of the workpiece. | 01-19-2012 |
| 20120006088 | BENDING DEVICE - A bending device is provided with a bending mechanism, a fixing table, an articulated robot, and a control unit. Control performed by the control unit includes a bending/movement control in which a workpiece is moved by clamping the workpiece by the bending mechanism and moving the bending mechanism by the articulated robot, and the workpiece is bent by the bending mechanism while the workpiece is being moved. | 01-12-2012 |
| 20110132056 | Pressing device for bending - The present invention provides a pressing device for bending, in which a pipe is held between a bending die having a shape corresponding to a shape of bending and a clamping die revolvable around the bending die, and, when the pipe is bent by revolving the clamping die around the bending die, an axial compression force is applied to the pipe. The pressing device for bending includes a movable table arranged movable in an axial direction of the pipe, a first cylinder provided to the movable table and able to press a rear end of the pipe, and a second cylinder provided to the movable table and able to press a fixed side in a direction opposite to a direction in which the first cylinder presses the pipe. | 06-09-2011 |
| 20100307214 | Bending Device - A bending device includes a bending mechanism for holding an elongated workpiece between a bending die and a clamping die revolvable around the bending die, and revolving the clamping die, to thereby bend the workpiece. The bending device includes a fixing base on which the bending mechanism is mounted, and an articulated robot on which a chuck mechanism for holding the workpiece is mounted and which moves the chuck mechanism. | 12-09-2010 |
