A pressured lubricating system will feed the lubricate oil into the closed screw-nut system by means of particular pipeline, and type an oil display screen between each touching elements to cut back the components friction when press works. A plurality of pinions partaking within the mentioned toothed rim are each driven by an oil-hydraulic axial piston motor or by a pair of oil-hydraulic axial piston motors and the axial piston motors along with the pinions are disposed on a platform surrounding the upper cross member of the press frame. No. 3,359,608, issued to the present inventor, discloses a friction and screw press for the manufacture of ceramic articles. In response to the information show: knowledge disparity, because the double-disc friction press operation will exist when stealing hammer, lacking hammer phenomenon, the output shall be floater than the CNC electric screw press, but according to the provisions of the corporate to suppress the hammer products, Two kinds of strain brick gear manufacturing are comparable. Furthermore, it’s potential to regulate the motion of the flywheel 7″ and screw 7′ by operating a hydraulic motor 7, having a comparatively reduced dimension, installed on the beam 8 to move the screw 7 through a detachably coupled system which is hydraulically interconnected to pistons 9, 9′. Line 41 illustrates the return of the screw, which has to be thrown in an up motion with a power of much less value than that supplied for the elastic return of the structure of the urgent machine. The pressure exerted by the screw 7′ on the material may be predetermined in a precise method, with the possibility of utilizing restricted torque generators for the stroke of the flywheel, resembling hydraulic motors, electric motors or friction motors with limited torque relatively to the motor used up to this moment. In the course of the acceleration phases for the downward movement and the upward motion of the spindle 9 the electrical motor 28 operates with approximately fixed power and fixed rotational velocity which ensures a excessive degree of electrical efficiency of the motor 28. The constant motor power is converted and fully utilized by the oil pump 27 working as a torque converter. Stated circuit additional comprising management means for controlling the stress of the hydraulic fluid fed to said motor means and a plurality of stress levels, one in all stated levels being controllable as braking pressure for said flywheel, and a refill pump means for returning leaked hydraulic fluid to said circuit.
