<p>A rotary forging or upsetting machine comprising an upper platen(15) and a lower platen (13), the lower platen (13) being rotatable about an axis (Zi) and the upper platen (15) being rotatable about an axis (Zz) which intersects the axis (Z1),the upper platen (15) being mounted on carrier (17) which is pivotable about an axis (A-A) which passes through the point of intersection of the axes (Z1 and Z2), means (19) being provided for adjusting the angle (a) of the upper platen (15) whilst the platens (15, 13) are rotating, and means (11) being provided for applying a force (F) to the lower platen (13) to move it towards the upper platen (15) so that a workpiece (14) carried by the lower platen (13) is deformed by the upper platen (15) moving around the workpiece (14).</p> |
