The beneficial effects of the utility model:
The utility model unit to depress the power construction weight be 0.21T/T, existing large hydraulic press reduces manufactured materials 24%, is equivalent to reduce equivalent cost 12%, improves China manufacturing position of resetting in the whole world, maximum tonnage is 165MN in 14 press in the whole world.
2. the utility model is by introducing PLC control, and the number of strokes is brought up to 15 times/minute by 6 times/minute, improves operating efficiency 50%; High control accuracy, can realize the flat-die forging precise treatment, reduce and forge surplus 55%; Raise labour productivity 50%, realize that synthesis energy saving is more than 30%; High headroom distance, big table top, raising Chinese large-sized open die forgings autogamy rate and maximum forging manufacturing create conditions, and for the whole world provides the large commercial forging, play the effect of actively promoting to fostering integration with the global economy.
3, the utility model employing oil is medium, the hydraulic press of existing ten thousand tons of aqueous mediums, and using water wisely reduces water treatment link and sewage discharge, and very big social benefit is arranged.
4. the utility model adopts all-welded structure, designs 170MN (17000T) free-forging hydraulic the biggest in the world, has broken through the cast-in-block traditional mode.On heavy hydraulic press, adopted booster, made the medium oil pressure bring up to 35MPa by 25MPa.Adopt the PLC control technology, can finish various technological actions various and the manipulator interlock, implementation procedure monitoring and Long-distance Control, micro-control speed realizes 0.002mm/s～0.5mm/s simultaneously.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is hydraulic schematic diagrams of the present utility model.
Accompanying drawing 3 is the utility model electrical schematic diagrams.
The specific embodiment:
Embodiment 1:
Free-forging hydraulic, its composition comprises: oil cylinder 1, described oil cylinder 1 with decide beam 2 and be connected, describedly decide beam 2 and be connected with moving beam 3, described moving beam 3 is connected with travelling table 5 by four columns 4, described travelling table 5 is connected with workbench 6.
Described free-forging hydraulic, described free-forging hydraulic has the PLC control, described PLC control comprises a mushroom scram button, the time relay, described oil cylinder 1 is connected with one way sequence valve 7, described one way sequence valve 7 is connected with four-way change-over valve 8, and described four-way change-over valve 8 is connected with solenoid directional control valve 9 respectively.
Supercharging speed-raising, the raising number of strokes mainly are by bidirectional variable hydraulic pump fuel feeding with medium oil, after pressure is the accumulator, energy storage of 25MPa, by booster medium oil is pressurized to 35MPa again, cut down by straight moving order, supplying with two-way ram rod oil cylinder (Φ 1800mm+2 * Φ 1400mm) respectively, to promote slide block (moving beam) descending soon.
