Experimental Vibrating Complex for the Research of Pressing Processes of Powder Materials

An experimental complex on a high pressure casing was developed for the research of vibrating processes of powder materials pressing. As a high pressure casing hydraulic hoses of high pressure pressed to the elliptic state were used. Hydraulic pump—a pulsator—is the upgraded gear pump in which a quarter of one tooth was cut. The modes of transition of a hydraulic motor through resonance were investigated. It is proposed to use the mode of fluctuation switching from coordinate X to Y and vice versa to create vibrating actuators of periodic action with a large vibration traction effort due to the massive energy storage. The developed experimental complex can be used both for one-sided and for dry isostatic pressing. The complex allows to implement spatial variations of the press-mould. The frequency and oscillation amplitude can be regulated. The frequency can be regulated by changing the turns of the hydromotor, and the amplitude—by changing the pressure values in the system. The method of calculating vibration modules on a high pressure casing is developed.
