ELECTRIC POWDER MOLDING MACHINE.

摘要

This invention provides an electric powder molding machine capable of controlling a molding pressure accurately and carrying out a regulating operation simply while a die/punch mechanism is replaced by another in accordance with the changed molding conditions. This machine is provided with a die/punch mechanism consisting of a die and upper and lower punches which define a force space, and which are disposed so that the die and punches can be moved relatively for compression molding a powdered material packed in this space, a driving mechanism having upper and lower driving parts for operatively connecting the punches to a servomotor, a means for detecting a molding pressure occurring as one or both of the punches are moved with respect to the die by the driving mechanism, and a means for controlling the drive of the servomotor on the basis of an output signal, which is representative of an actual molding pressure, from the detecting means so that the molding pressure attains a predetermined level.
