Forging Screw Press
This Screw Press is also known as Forging Presses or Screw Presses. A pressured lubricating system will feed the lubricate oil into the closed screw-nut system by means of particular pipeline, and form an oil display screen between every touching parts to scale back the components friction when press works. A plurality of pinions partaking within the mentioned toothed rim are each pushed by an oil-hydraulic axial piston motor or by a pair of oil-hydraulic axial piston motors and the axial piston motors together 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 line with the info 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, however according to the provisions of the company to suppress the hammer products, Two sorts of stress brick equipment production are comparable. Furthermore, it is potential to control the movement of the flywheel 7″ and screw 7′ by operating a hydraulic motor 7, having a comparatively lowered dimension, installed on the beam 8 to maneuver the screw 7 through a detachably coupled system which is hydraulically interconnected to pistons 9, 9′. Line forty one illustrates the return of the screw, which needs to be thrown in an up movement with a power of much less value than that provided for the elastic return of the construction of the urgent machine. The strain exerted by the screw 7′ on the fabric could also be predetermined in an exact method, with the potential of using restricted torque turbines for the stroke of the flywheel, reminiscent of hydraulic motors, electrical motors or friction motors with limited torque relatively to the motor used up to this moment. Throughout the acceleration phases for the downward motion and the upward motion of the spindle 9 the electric motor 28 operates with roughly constant energy and constant rotational velocity which ensures a excessive degree of electrical efficiency of the motor 28. The fixed motor power is converted and absolutely utilized by the oil pump 27 working as a torque converter. Stated circuit additional comprising control means for controlling the strain of the hydraulic fluid fed to stated motor means and a plurality of pressure stages, one of stated stages being controllable as braking stress for said flywheel, and a refill pump means for returning leaked hydraulic fluid to mentioned circuit.

SD10-315 was the primary set Refractory Electrical Program-controlled Screw Press for Refractory industry in China which was our firm developped and produced, even the primary set on the planet. Shortly earlier than the affect of the higher half of the forging die, secured to the slide 7 upon the forging work-piece lying within the decrease half of the forging die, the strains 31 to the axial piston motor 26 are short-circuited, as the magnetically controlled 4-means valve 41 is moved from its relaxation place (as proven in FIG. This Friction Screw Press Down Stroke has been developed from best grade metal. This machine is also suitable for producing naushadar bricks and head refractory. Swap 23 energizes the valve 17 to disconnect the pilot of a examine valve 22 and introduces oil at a pressure of one hundred atmospheres into the chambers 15 and 15′ of dynamic oil accumulators 14, 14′ which can be hydraulically linked to pistons 13, 13′ as proven in FIGS. The torlence of controlling energy of Electrical Screw Press is zero.2%, and the torlence of impact power is only one%. The small portions of oil running off from the strain-limiting valves forty two and 43 and the 4-means valve forty one throughout the reversing and also as leaked oil are fed back once more into the closed circuit by a pump forty five pushed by a motor forty four. A spring-centered, strain-managed three-method valve forty six is supplied so as to ensure the feed strain required on the pump 27 and regulated by the pressure-limiting valve 47. The three-way valve 46 is actuated in such a way that the respective low-strain side of the closed circuit is related to the pressure-limiting valve forty seven, the feed stress being maintained by the pump forty five. For cleaning and cooling the oil, the oil which has escaped from the circuit, is collected partially 32b of the tank 32, handed on after preliminary cleansing by sedimentation to half 32c of the tank 32, is fed via filters 50 and coolers fifty one by a pump 49 driven by an electrical motor forty eight and is saved in part 32a of the tank 32. Due to this fact, instead of ending the primary urgent with the worth of the pressing, the amount of oil at high pressure could also be used. The electric screw press is pushed by everlasting magnet synchronous servo motor,and consist of mechanical pats akin to framework, flywheel, screw nut, the slider, lubricating mechanism, braking mechanism and electrical elements similar to servo motor, electric management cupboard, operating button station.
