HYDRAULIC PRESS Russian patent published in 2017 - IPC G05D15/00 B28B3/02 B30B11/00 

FIELD: mechanisms.

SUBSTANCE: invention relates to mechanical forces control and adjustment devices, specifically to construction materials production equipment. Construction articles compaction hydraulic press contains pressing device bed, control unit, connected with upper and lower cylinder blocks, movable loading trolley, compaction chamber and mixture supply bin. On cylinder blocks upper and lower male dies are installed, directed towards each other. Every cylinder block consists of three hydraulic cylinders, one main and two leveling. In each hydraulic cylinder rods displacements sensors are installed, connected to control unit. Levelling high-speed hydraulic cylinders are made with possibility of changing male dies position and their alignment so, that molding chamber volume varies depending on displacement sensors readings. Control unit is made with possibility of articles geometrical sizes setting and control based on displacement sensors readings. Loading trolley is equipped with position sensors and pneumatic clamps for displacement of articles.

EFFECT: enabling increase in efficiency and molded articles quality.
