Abstract

The portable tube beanding machine consists of a hand operated hydraulic pump, to which a bending tool is attached. The pump has an oil reservoir from where oil is drawn into the master cylinder. The piston of this cylinder is outstroked by a compression spring and returned by an external hand operated lever. This forces the oil in the cylinder through a check valve into the working cylinder which in turn outstrokes piston to which a bending former is attached. To return the spring loaded working piston to its retracted position, the hand lever is pressed into its innermost position so that the two check valves are opened, thus allowing the oil to return to reservoir.
