ABSTRACT:
The high force rebar bending machine comprises a frame which carries a bending die. An arm is pivoted to swing around the bending die with a bending roller thereon. Rebar engaged by the bending roller is bent around the die as the arm swings. A fluid cylinder has its piston connected to a cable. The cable is wrapped around a large drive wheel which, in turn, is connected to the arm so that bending force is multiplied. The entire structure is sufficiently compact and light to be portable for use at a job site.
