Rebar cutter and bender
摘要:
A portable devic for bending and cutting rebar, reinforcing rod, and the like. For cutting, a shaft assembly is movable along a first longitudinal axis (A-A) between a retracted and an extended position. A movable cutting head carried by the shaft assembly coacts with a fixed cutting head to shear rebar disposed between the cutting heads when the shaft assembly is moved to the extended position. For bending, a push rod movable along a second longitudinal axis (C-C) parallel to the first axis (A-A) couples movements of the shaft assembly through a clevis to a crankshaft such that longitudinal movements of the shaft assembly cause rotational movements of the crankshaft about an axis substantially perpendicular to axis (A-A). A first driven wheel, mounted for rotation with the crankshaft, has one or more bending blocks attached to the wheel by a radial arm. Rebar inserted in a gap between the first wheel and a second, idler wheel, is bent by the bending blocks as the wheels rotate in response to movement of the shaft assembly from a retracted to an extended position.
