The principle of centralized oil supply hydraulic system 4 as shown in figure 10, comprise oil sources loop 401 and press loop 402, whole piece pressing production line configuration one cover oil sources loop 401, every the hot press 2 in the production line all dispose a cover press loop 402 (the two cover press loops 402 of only drawing among the figure).Adopt an oil sources loop 401 to be divided into high-pressure oil feed loop, low pressure oil supply loop and a plurality of press loop 402 energy storage pressing mode and realized many hydraulic press centralized oil supplies and every independent controlled function of hydraulic press operating pressure.

The high and low pressure mode of fuel feeding is respectively adopted in oil sources loop 401 of whole system device, oil sources loop 401, is divided into low pressure oil supply loop and high-pressure oil feed loop.Low pressure oil supply loop comprises low pressure fuel pump B1, low pressure accumulator C1, low pressure unloading overflow valve V1 and low pressure switch S 1, low pressure fuel pump B1 is connected in parallel by oil circuit and unloading overflow valve V1, and being connected with pressure switch K1 and low pressure accumulator C1, the low pressure oil sources is through check valve output low pressure P1.Low pressure oil supply loop detects the force value of low pressure P1 by pressure switch K1, and when low pressure P1 was lower than threshold value, low pressure fuel pump B1 was in running order, and when low pressure P1 reached setup pressure value, low pressure fuel pump B1 was by unloading overflow valve KV1 off-load.Low pressure accumulator C1 is used to low pressure oil supply loop that big flow oil stream is provided.The high-pressure oil feed loop comprises high-pressure oil pump B2, high pressure unloading overflow valve V2 and high-pressure switch S2, and high-pressure oil pump B2 is connected in parallel by oil circuit and unloading overflow valve KV2, and is connected with pressure switch K2, and high pressure fuel source is through check valve output high-pressure P2.The high-pressure oil feed loop detects the force value of high-pressure P2 by pressure switch K2, and when high-pressure P2 was lower than threshold value, high-pressure oil pump B2 was in running order, and when high-pressure P2 reached setup pressure value, high-pressure oil pump B2 was by unloading overflow valve KV2 off-load.

Low pressure fuel pump B1 and high-pressure oil pump B2 adopt unloading overflow valve, detect and control by unloading overflow valve KV1 and unloading overflow valve KV2 the off-load of oil pump by pressure switch K1 and pressure switch K2.When whole central lubricating system oil cylinder was in motionless state, low pressure fuel pump B1 and high-pressure oil pump B2 were in unloading condition.When one in the whole central lubricating system or several hydraulic presses are in the F.F. duty, detect low pressure P1 when being lower than threshold value by pressure switch K1, low pressure fuel pump B1 is in running order.

Every hydraulic press device one cover press loop 402.The circuit type that closing liquid cylinder pressure 206 in press loop 402 employing high-low pressures difference fuel feeding, the hydraulic press and stamped fluid cylinder pressure 207 are controlled respectively.Press loop 402 comprises commutation loop and high-voltage energy storage loop, comprise compacting cylinder reversal valve V3 in the commutation loop, closing cylinder reversal valve V4, compacting cylinder unloader V7, closing cylinder unloader V8, compacting cylinder pressure transducer S1 and closing cylinder pressure sensor S2, low pressure oil supply loop is connected with stamped fluid cylinder pressure 207 with closing liquid cylinder pressure 206 with closing cylinder reversal valve V4 by compacting cylinder reversal valve V3, compacting cylinder unloader V7 is connected with the rear end of compacting cylinder and closing cylinder respectively with closing cylinder unloader V8, is respectively equipped with compacting cylinder pressure transducer S1 and closing cylinder pressure sensor S2 in connecting oil circuit.Compacting cylinder unloader V7, closing cylinder unloader V8 are used for closing liquid cylinder pressure 206 and stamped fluid cylinder pressure 207 release cylinder internal pressure before commutation.The high-voltage energy storage loop comprises high-voltage energy storage device C2, energy storage valve V5 and pressurizing valve V6, and the high-voltage energy storage loop is in series with a pressurizing valve with the hydraulic press compacting being connected of cylinder in the oil circuit, applies high-pressure work pressure by pressurizing valve for the compacting cylinder.The hydraulic oil of the low pressure P1 that low pressure fuel pump B1 provides is used for the duty of F.F., rewind down stroke and the closing liquid cylinder pressure 206 of closing liquid cylinder pressure 206 and stamped fluid cylinder pressure 207.The hydraulic oil of the high-pressure P2 that high-pressure oil pump B2 provides is controlled to high-voltage energy storage device C2 energy storage to pressing pressure P3 through energy storage valve V5, and when stamped fluid cylinder pressure 207 was in compacting and packing state, pressing pressure P3 gave through pressurizing valve V6 and suppresses cylinder 4 fuel feeding.Energy storage valve V5, pressurizing valve V6, compacting cylinder unloader V7 and closing cylinder unloader V8 all adopt Leakless valve.Because each stamped fluid cylinder pressure 207 in the hot press 2 links together by pipeline, so each stamped fluid cylinder pressure 207 is fuel feeding simultaneously.

When the hydraulic press fast travel, reversal valve V3 and reversal valve V4 are in the oil cylinder upward position, the closing liquid cylinder pressure 206 of hot press 2 and stamped fluid cylinder pressure 207 rely on low pressure P1 up, when closing liquid cylinder pressure 206 and stamped fluid cylinder pressure 207 all put in place, the rodless cavity internal pressure that pressure sensor S2 detects closing liquid cylinder pressure 206 and stamped fluid cylinder pressure 207 reaches low pressure steady pressure P1, and fast travel finishes.Pressurizing valve V6 opens, and by the pressing pressure P3 injection stamped fluid cylinder pressure 207 of high-voltage energy storage device C2 energy storage, hydraulic press is in pressing stage.In the compacting starting stage, because the density behind the material pressurized changes, stamped fluid cylinder pressure 207 has a small stroke to be changed, and at this moment is compacting cylinder makeup oil stream by high-voltage energy storage device C2, when the system pressure value stabilization reached operating pressure P3, system was in packing stage.

In the compacting initial procedure, when the operating pressure P3 of high-voltage energy storage device C2 reduced to a threshold value, control system was opened energy storage valve V5 and is given high-voltage energy storage device C2 energy storage, makes pressing pressure maintain operating pressure P3 all the time.

At packing stage because all there is interior leakage in hydraulic system, utilize Compressed Gas in the accumulator characteristic changing the rigidity characteristics of hydraulic system, under the situation of minute leakage, adopt the energy storage pressurize, the variation that can make pressing pressure is below 1%.Dwell pressure changes in the precision more than 5% when being better than common hydraulic press employing off-load pressurize and shutdown greatly.

When one in the whole central lubricating system or several press during in operating pressure P3 energy storage, compacting and pressurize duty, pressure sensor S1 by each press loop 402 detects operating pressure P3 pressure separately, when being lower than threshold value, B2 is in running order for the control high-pressure oil pump.

Energy storage valve V5 can adopt pid control algorithm (in process control, controlling in ratio (P), integration (I) and the differential (D) of deviation), further improves the precision of operating pressure P3.Because the operating pressure P3 of every hydraulic press can set separately, thereby makes each hot press to produce under different operating pressures, product that promptly can the production different cultivars.

Centralized oil supply hydraulic system 4 is utilized the discharge characteristic and the pressure characteristic of accumulator, makes hydraulic system become elastic system by rigid system, realizes many hot presses high flow rate oil supply in parallel and the constant pressurize of hot press variable pressure.
