<p>A method of flow forming in a tensile direction. More particularly, it comprises flowing the metal on the surface of a sheet (or plate) metal blank (10) from a center radially outwards. A roller (r) is initially engaged near or at the center of a rotating metal blank. The roller is then moved radially outward to the edge of the metal blank, gathering the metal as it moves. A mandrel tool surface is used to accumulate the gathered metal to form a predetermined shape at the edge of the workpiece, such as v-belt or multi-ribbed v-belt profile, or gear or sprocket tooth profile.</p> |
