ABSTRACT:
A die control speed rate conversion device for a powder mold press wherein the timing for oil release from a hydraulic circuit can be obtained by the angle signal (position signal) from a rotary encoder on the main axis of the press actuating synchronously with an upper punch, and the speed of descent of a die relative to an upper ram can be controlled at any rate ranging from 1:1 to 1:1/4 by a sevomotor controlled by the signal from a linear sensor detecting the movement of the upper ram.
