Abstract: A tubing bending machine comprising a bending assembly further comprising a hydraulic cylinder which reciprocates a plurality of bands set apart by guide discs, with each band being held in place by a forming die having two threaded ends which are secured to the hydraulic cylinder by means of nuts. The bending assembly is mounted vertically in a frame, on which two tubing guides are also mounted by means of bearings. The tubing guides have alignment guides corresponding to each band on the bending assembly and are oriented such that when a piece of tubing inserted in the machine is resting on the tubing guide, the piece of tubing will be aligned with a corresponding band and forming die.

Abstract: A tubing swaging machine comprising four coplanar hydraulic cylinders which compress the end of a piece of tubing around a central mandrel. The central mandrel has indentations and is reciprocated by a fifth hydraulic cylinder perpendicular to the plane of the other four cylinders. Each of the four coplanar hydraulic cylinders reciprocate a die which has a surface corresponding to the indentation in the mandrel opposite.
