Tooling for making pointed headed bolts of a given diameter in numerous lengths with roll thread ready threaded to the head and partially threaded shanks in a four forming station forming machine, the tools being configured to work on wire stock as received at the first station of a diameter larger than or substantially the same as the roll diameter and not greater than the nominal diameter of the bolt, including at least two sequential head forming tools for mounting on the slide, an extrusion pointing tool for mounting on the die breast, a roll diameter extrusion tool for mounting on the die breast and a head support tool mountable in a station on the slide at multiple axial positions corresponding to standard lengths of the bolts being made, the head support tool being arranged to work at either the extrusion pointing station or the roll diameter extrusion station.
1-4. (canceled)
A tool assembly for axially supporting the head of a bolt being formed in a forging machine comprising a central body having a face arranged to abut the bolt head and a carrier for locating the central body at multiple axially spaced locations corresponding to differences of lengths of standard bolts being made by the tool.
11-13. (canceled)
A progressive forging machine having a die breast with a plurality of die stations for receiving parts being progressively formed in the machine, a tool case in at least one of said die stations, a kick out pin for ejecting a part from said one die station, the kick out pin having a longitudinal axis and a forward end with a formation capable of rotationally interlocking with a part received in said one die station, a hard plate disposed at the rear of said tool case arranged to sustain axial forming loads on tooling in said case, said kick out pin extending through said hard plate, said hard plate including a restraining surface arranged to permit said kick out pin to move longitudinally while restraining it from rotation about a longitudinal axis, and instrumentalities to lock said hard plate relative to said tool case against rotation about an axis parallel to said longitudinal axis of said kick out pin.
