Summary

The paper presents further results of the research which has been pursued by the authors into the subject of rotary forging with an experimental machine using pure lead as a model material to simulate the forging of hot steels. Solid circular cylinders of different height/diameter (H/D) ratios, and also hollow circular cylinders of constant internal/external diameter ratio (d/D = 0.5) but different H/D ratios, were upset slowly by rotary forging involving different magnitudes of axial force. The interrelationship between the axial force, number of revolutions of the upper rotary platen and the resulting deformation of the cylinders was investigated. This interrelationship is presented in a simple and convenient form which is intended to assist designers or users of this type of unconventional machine. Experimental results are also given for the energy required to rotary forge the solid circular cylinders.
