Abstract:

A rebar fabricating machine is provided that is capable of processing either straight rod stock material or coil stock material. The rebar fabricating machine comprises a main cabinet, a horizontal power driven straightening module mounted adjacent to the upstream end of the main cabinet, a main drive module, a vertical straightening module, an encoder roll, a shear device and a bending head all mounted on the interior of the main cabinet. The main drive module includes a plurality of upper rolls each having a hydraulic cylinder attached thereto and a plurality of lower driven rolls driven by a single drive motor. The vertical straightening module includes a plurality of adjustable upper and lower straightening rolls. The horizontal straightening module is pivotally mounted on a base so that the horizontal straightening module can be selectively removed from the path of travel of the stock material. A swing up door is mounted on the main cabinet adjacent the main drive module so that when the swing up door is open, power to the hydraulic cylinder attached to each upper roll is interrupted so that the stock material cannot be fed into the fabricating machine.
