ABSTRACT:
A cutter/bender apparatus is provided for selectively cutting and bending a workpiece. The bending member includes a bending pin actuated by a hydraulic cylinder that moves the bending pin into and out of engagement with the workpiece to clamp the workpiece against a support plate. When clamped, another hydraulic cylinder lifts a movable bending member toward the workpiece, bending the workpiece about the bending pin in the process. The cutting member includes a fixed cutting member and a movable cutting member mounted in side to side abutment. The cutting members include a slot that extends laterally therethrough in which the workpiece to be cut is placed. The hydraulic cylinder that operates the movable bending member also provides motion for the movable cutting member. As the movable cutting member moves, it moves the aligned slots of the individual cutting members out of alignment, shearing the workpiece in the process. The cutter/bender apparatus may be attached to a loader vehicle using its hydraulic power for actuation or may include an independent power source. A carrier rack for the apparatus facilitates handling, positioning, and transport of the workpieces. Safety features, including a safety shut-off switch and a coupler member, incorporated into the apparatus make its use with a loader vehicle safer.
