<p>A wire bending device (10) includes an upright frame (12) and a wire feed hopper (20) for dispensing wire rods (100). A wire bending section (40) is mounted on the frame (12), and at least one transport arm (42) is pivotally mounted on the frame (12), the transport arm (42) operative to transport wire rods (100) from the hopper (20) to the wire bending section (40). The wire bending section (40) includes a wire securement device (51) mounted on the frame (12), the rotatable wire securement device (51) operative to secure one end of a wire rod (100) and rotate the wire rod (100) about its longitudinal central axis and a wire bending unit (101) movably mounted on the frame (12). The wire bending unit (101) includes a wire bend head (134) aligned with the center longitudinal axis of the rotatable wire securement device (51), the wire bending unit (101) adapted to move on the frame (12) such that the wire bend head (134) remains aligned with the center longitudinal axis of the rotatable wire securement device (51). A control unit such as a programmable computer is operatively connected to the transport arm (42), the rotatable wire securement device (51) and the wire bending unit (101) to engage the transport arm (42) to transport a wire rod (100) from the hopper (20) to the wire bending section (40), engage the rotatable wire securement device (51) to secure one end of the wire rod (100), move the wire bend head (134) to determined bend locations on the wire rod (100), rotate the wire rod about its longitudinal central axis to programmed positions, and engage the wire bend head (134) to perform the programmed bend in the wire rod (100).</p> |
