MECHANICAL TOGGLE AND FLUID ACTUATED RAM FOR POWDER COMPACTING PRESS

摘要

The press for compacting powder material is provided with a mechanical toggle mechanism actuated ram disposed above the die supporting bed or table of the press. The mechanical toggle mechanism is in turn actuated by the press drive. The pivot support for the ram upper toggle arm is independently reciprocated by a fluid cylinder activated in timed relationship with the mechanical toggle action such as to provide reciprocation caused by the toggle mechanism. Adjustable abutment devices are provided for adjustably setting the extreme positions of the fluid cylinder reciprocating member.
