Patent ID: 7536890

Claim:
Apparatus for bending metal stock comprising: a) a support; b) an arm with at least a portion of one end being a slide bar, the slide bar end of the arm being attached to the support with the arm extending outwardly therefrom; c) a slide having means for slideably attaching the slide to the slide bar resulting in the slide translating linearly along the slide bar relative to the support, the slide and slide bar having securing means for preventing movement of the slide relative to the slide bar at a plurality of locations; d) a die, a form roller, and a lever, the lever having means for pivotably mounting the form roller thereon, the arm having means for pivotably mounting the die and an end of the lever to the end of the arm opposite to the support, the apparatus being sized to rotate the form roller around the die at a predetermined distance when the lever is rotated around the die; e) a hydraulic cylinder having an extendable ram, with the cylinder and ram being pivotably connected between the lever and the slide, the apparatus being sized and arranged to rotate the lever around the die through a predetermined angle when the ram is extended over its full range; and f) a hydraulic source means for providing pressurized hydraulic fluid at various flow rates and pressures to the cylinder, the hydraulic source having operator control means for controlling the flow rates and pressure.
