ABSTRACT:
A cam assembly for mounting a pressure die to the arm of a standard pipe bending machine. The assembly comprises a base with a pivot post extending upwardly therefrom. A cam shaft has an off-center opening adapted to receive the pivot post. A pivot assembly is combined with the pressure die and has an opening adapted to receive the cam shaft so that movement of the cam shaft around the pivot post changes the position of the pressure die relative to the bending machine's arm. Movement of the pivot assembly around the cam shaft swings the pressure die out of the way to load and unload the pipe being bent.
