Beschreibung
Zusammenfassung:	The present invention relates to an apparatus for controlling a pressure rise rate and an extrusion speed of a propellant extrusion press, and a method thereof, wherein the apparatus comprises: a pressure rise rate control unit for fixing a pressure rise value of a hydraulic pressure unit when the pressure rises at a beginning of extrusion during formation of lead-free chemical propellant for artillery, and controlling a pressure rise rate of a cylinder by adjusting a flow rate of the hydraulic pressure unit to a preset speed; and an extrusion speed control unit for fixing the pressure of the hydraulic pressure unit when the extrusion is performed after the pressure rises in the beginning of the extrusion, and controlling the extrusion speed of the cylinder uniformly by adjusting the flow rate of the hydraulic pressure unit to the preset speed. 본 발명은 추진체 압출 프레스의 압력 상승 속도 및 압출 속도를 제어하는 장치 및 그 방법은 화포용 무연화약류 추진체 성형 시, 압출 초기에 압력이 상승되면, 유압 유니트의 압력 상승 값을 고정시킨 후, 유압 유니트의 유량을 기 설정된 속도로 조절하여 실린더의 압력 상승 속도를 제어하는 압력 상승 속도 제어부 및 압출 초기에 압력이 상승 완료 후 압출이 실행되면, 유압 유니트의 압력을 고정시킨 후, 유압 유니트의 유량을 기 설정된 속도로 조절하여 실린더의 압출 속도를 일정하게 제어하는 압출 속도 제어부를 포함한다.
