Abstract:
A set of 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.
