Abstract: A bending device. The bending device may comprise: a frame, center die, two sliding dies, and one or more motors. The center die may be positioned at a distal end portion of the frame and may advance towards a proximal end portion of the frame along a first path guide. The first sliding die may be positioned at a left portion of the frame and may advance towards and approximately near the first bent portion of the center die along a second path guide. The second sliding die may be positioned at a right portion of the frame and may advance towards and approximately near the second bent portion of the center die along a third path guide. The motors may actuate the movement of the center die, the first sliding die, and the second sliding die.
