The forging forces do not act on the machine frame but are sustained by the Ram. A pressostat 18 calibrated at ninety ambiance, energizes a valve 20 which feeds a multiplier 21 taking the necessary pressure to the oil, with this strain being predetermined via a pressostat 19.

Line forty three indicates the extraction of the pressed half by the mould due to the piston commanded by the respective valves sixty three and 64 in synchronism with the beam and the screw in a new up motion achieved by known command circuits. SD10-315 was the first set Refractory Electrical Program-controlled Screw Press for Refractory industry in China which was our company developped and produced, even the first set on the earth. Shortly before the impression of the higher half of the forging die, secured to the slide 7 upon the forging work-piece lying in the decrease half of the forging die, the lines 31 to the axial piston motor 26 are quick-circuited, as the magnetically controlled 4-manner valve 41 is moved from its relaxation position (as proven in FIG. This Friction Screw Press Down Stroke has been developed from greatest grade metal. This machine is also appropriate for producing naushadar bricks and head refractory. Swap 23 energizes the valve 17 to disconnect the pilot of a check valve 22 and introduces oil at a stress of a hundred atmospheres into the chambers 15 and 15′ of dynamic oil accumulators 14, 14′ which may be hydraulically related to pistons 13, 13′ as shown in FIGS. The torlence of controlling power of Electric Screw Press is zero.2%, and the torlence of impact energy is only one%. The small portions of oil running off from the strain-limiting valves forty two and 43 and the 4-way valve 41 in the course of the reversing and in addition as leaked oil are fed back again into the closed circuit by a pump 45 driven by a motor 44. A spring-centered, pressure-managed three-method valve forty six is provided in an effort to make sure the feed stress required at the pump 27 and regulated by the pressure-limiting valve 47. The three-method valve 46 is actuated in such a manner that the respective low-stress aspect of the closed circuit is linked to the strain-limiting valve forty seven, the feed stress being maintained by the pump forty five. For cleansing and cooling the oil, the oil which has escaped from the circuit, is collected partially 32b of the tank 32, passed on after preliminary cleaning by sedimentation to half 32c of the tank 32, is fed by means of filters 50 and coolers fifty one by a pump forty nine pushed by an electric motor 48 and is stored partly 32a of the tank 32. Subsequently, as an alternative of ending the primary urgent with the worth of the pressing, the quantity of oil at excessive pressure may be used. The electrical screw press is pushed by everlasting magnet synchronous servo motor,and encompass mechanical pats resembling framework, flywheel, screw nut, the slider, lubricating mechanism, braking mechanism and electric parts similar to servo motor, electric control cabinet, working button station.
