Automated hydraulic device for CEC process engineering

Abstract

The paper presents a prototype automated hydraulic device for cyclic extrusion compression (CEC) process engineering. Presented device is a horizontal double hydraulic press equipped with electrohydraulic control system, designed using proportional technique and microprocessor control. A first part of this paper presents a structure and a working scheme of the device. A second part describes implemented device’s measurement and control circuit. Sample characteristics from extrusion process, recorded during press work, are presented in final part.
