Detailed description of the invention
Embodiment mono-:
As shown in Figure 1, the hydraulic control system for multidaylight press of the present embodiment comprises and being arranged under pressing plateFast lifting oil cylinder (not shown) and multiple pressurization oil cylinder 1 of side, each pressurization oil cylinder 1Cylinder barrel is provided with pressure oil joint, and pressure oil joint is communicated in pressure oil pipeline by forcing hose 515。
As Figure 1-3, on the cylinder barrel of each pressurization oil cylinder 1, be also provided with hydraulic control one-way valve 2, hydraulic controlThe oil-in of check valve 2 is communicated in fuel tank 3 by liquid-filling pipe 4, particularly, and hydraulic control one-way valve 2Oil-in by welding straight coupling be communicated with liquid-filling pipe 4, liquid-filling pipe 4 is communicated in fuel tank 3.The hydraulic control hydraulic fluid port of the hydraulic control one-way valve 2 in the present embodiment is communicated in signal oil pipeline 6, particularly, and liquidThe hydraulic control oil port of control check valve 2 is provided with signal oil joint, and signal oil joint is by signal oil flexible pipe61 are communicated in signal oil pipeline 6, and wherein, hydraulic control one-way valve 2 is preferably CF type prefill valve.
As shown in Figure 3, the oiler place of the pressure oil joint of each pressurization oil cylinder 1 is provided with high-pressure ball valve7, pressure oil pipeline 5 is provided with Pressure gauge, the pressure in Pressure gauge detected pressures oil-piping 5, byCylinder barrel in pressurization oil cylinder 1 communicates with pressure oil pipeline 5, when hydraulic control one-way valve 2 is closed, carrys out self-pressureThe high pressure of power oil-piping 5 is separated by hydraulic control one-way valve 2 with the low pressure in liquid-filling pipe 4, if hydraulic controlCheck valve 2 is revealed, and the pressure oil of cylinder barrel inner high voltage can be leaked to low pressure by hydraulic control one-way valve 2Liquid-filling pipe 4 in, the pressure oil pressure that now Pressure gauge on pressure oil pipeline 5 detects can underFall, this just illustrates and has at least a hydraulic control one-way valve 2 to have Leakage, at this moment needs first to close completeHigh-pressure ball valve 7 on the forcing hose 51 of portion, makes the pressure oil passage of cylinder barrel and pressure oil pipeline 5Disconnect, then open successively the high-pressure ball valve 7 on each pressurization oil cylinder 1, just can sentence according to Pressure gaugeDisconnected concrete which hydraulic control one-way valve 2 leakage of oils.
The using method of the above-mentioned hydraulic control system for multidaylight press is: in the time carrying out compression motion, manyThe fast lifting oil cylinder of laminating machine can rise jack-up pressing plate fast, and multidaylight press rises, pressurization oil cylinder 1Plunger can be taken up, in the cylinder barrel of the oil cylinder 1 that now pressurizes, produce vacuum, hydraulic control one-way valve 2 can quiltsSuction is opened, and the hydraulic oil in fuel tank 3 enters into pressurization oil cylinder through liquid-filling pipe 4 and hydraulic control one-way valve 2In 1 cylinder barrel, in the time that fast lifting oil cylinder stops rising, hydraulic control one-way valve 2 is closed automatically, thenBy pressure oil joint to pressurization oil cylinder 1 cylinder barrel in input pressure oil, allow pressurization oil cylinder 1 add at a slow speedPress, until complete pressurization. In the time that multidaylight press declines, fast lifting oil cylinder shrinks, synchronous signal oilEnter into hydraulic control one-way valve 2 inside by signal oil pipeline 6, open hydraulic control one-way valve 2, hydraulic oilIn the cylinder barrel of pressurization oil cylinder 1, be back in fuel tank 3 through hydraulic control one-way valve 2 and liquid-filling pipe 4.
Because each pressurization oil cylinder 1 is furnished with hydraulic control one-way valve 2, oil circuit is smooth and easy, multidaylight press rising,Decrease speed is fast, and in addition, when pressurization, the pressure of hydraulic oil is shared by multiple hydraulic control one-way valves 2, topping upPipeline 4, without high pressure, improves the service life of liquid-filling pipe 4.
Should be appreciated that specific embodiment described above is only for explaining the utility model, and need notIn limiting the utility model. Apparent variation or the change of being extended out by spirit of the present utility modelMoving still among protection domain of the present utility model.
