Abstract
A forming tool in accordance with the present invention is provided which includes a forming wheel, a shaft, a tool holder, bearings, washers, locking plate, locking bolt, and nut. The forming tool is for use with a lathe to form a journal on the ends of extruded tubing consisting of a variety of materials having various wall thicknesses. The forming operation in accordance with the present invention occurs when the lathe's turret moves the forming tool to cause the forming wheel to contact a portion of the extruded tube, which is rotated by the lathe's spindle. As a result of the contact, metal material is displaced on the extruded tube, and a journal is formed on the extruded tube. In accordance with one aspect, the forming tool is returned to its starting position by contacting a portion of the extruded tube as the forming wheel is moved away from the spindle of the lathe. In accordance with another aspect, the forming wheel includes a forming edge, which is the portion of the forming wheel that contacts the extruded tube when the forming operation occurs. The forming edge extends a length L.sub.E from the body of the forming wheel to allow the forming wheel to contact the extru…
