Embodiment
The utility model is described in detail with reference to Figure of description.
As shown in Figure 1 to Figure 3, the cubic hinge press synchronous centering that the utility model is provided automatically controls standby pressure adjustable system
It is arranged on：Six hydraulic cylinders parallel with one another of cubic hinge press, are followed successively by pushing cylinder 41, rear cylinder pressure 42, left cylinder pressure 43, upper pressure
Cylinder 44, preceding cylinder pressure 45 and right cylinder pressure 46.The low pressure for additionally include the oil pump for hydraulic pressure oil supply cylinder, being connected with hydraulic cylinder respectively is supplied
Synchronous centering unit, synchronous centering unit are provided with the oil return circuit of each hydraulic cylinder of oily unit 7 and high-pressure oil feed unit 8.
Including：
Series-parallel 6 electromagnetic hydraulic pressure reversal valves 1 are corresponded with each hydraulic cylinder respectively, and are preferred to use electromagnetic hydraulic pressure and are changed
To valve, and the 6 hydraulic pressure position-sensing switches 3 connected one to one respectively with each hydraulic cylinder, hydraulic pressure position-sensing switch 3 is according to each hydraulic pressure
Corresponding electromagnetic hydraulic pressure reversal valve 1 is controlled to open and close during cylinder row to pre-determined synchronization position；Additionally include contact-making switch, contact-making switch
Do not represent in the example shown, it is connected on the electromagnetic hydraulic pressure reversal valve of circuit system, for according to hydraulic pressure position-sensing switch 3
