ABSTRACT:
An extrusion assembly, which fits into a hydraulic press, includes an upper die plate and a lower die plate mounted to one another by die guide posts. A lead bar is coupled to the upper die plate at one end and to a mandrel at its other end and includes helical grooves on its surface that mate with helical protrusions on lead nuts. A die shell and insert are mounted concentrically with mandrel and receive a gear blank. As hydraulic press pushes lead bar axially toward gear blank, lead nuts impart a rotational motion to lead bar, which causes mandrel to move with a helical motion as it is pressed into and pulled out of gear blank.
