Summary

This study discusses the important characteristics of forging presses and describes methods for determining them. A 700 ton hydraulic press, a newly installed 500 ton mechanical press of scotch yoke design, and a 400 ton screw press were used in the study. In all threepresseshigh-temperature ring-compression tests were used to determine the practical effect of press speed on die chilling, metalflow and load requirements. In the mechanical press, room temperature copper upset tests were employed to determine the dynamic press stiffness, the offcentre loading ability, the flatness of ram and bolster surfaces under load and the available energy capacity at various production rates.

The methods used in the present study can be applied for the evaluation, comparison and standardisation of forging presses under practical production conditions.
