Abstract

The tool assembly forms internal threads on the interior surfaces of tubular structures. A cylindrical tool holder defines circumferentially about one end, a series of disc-shaped forming edges. The tool holder is adapted for rotational contact with a tubular workpiece. A rotating drive is located in operative contact with the tool holder and is situated for longitudinal reciprocation along an inclined track. Opposed clamps are located on a base structure to secure the workpiece in axial alignment with the tool holder. A track comprises paired track members of rails associated with the workpiece securement, with the track inclined w.r.t. the horizontal to enable the tool holder to traverse the interior of the workpiece.
