Embodiment
As depicted in figs. 1 and 2, the synchronous fuel tank oil circuit control device of a kind of modified node method described in the present embodiment, it is the flanging oil cylinder 11 needing synchronization motion for four of controlling cooker forming machine, form primarily of four flanging oil cylinders, 11, first electromagnetic direction valve, 31, second electromagnetic direction valve, 32, electromagnetic relief valve, 4, one-way throttle valve, 5, two-way relief valve 6 and an one-way valve 8, and the first electromagnetic direction valve and the second electromagnetic direction valve are 24 logical electromagnetic direction valves.
A rod chamber access in parallel rod chamber oil circuit 21 respectively of four flanging oil cylinders 11, this rod chamber oil circuit 22 is connected with the first interface (B mouth) of the first electromagnetic direction valve 31 by one-way throttle valve 5.Second interface (P mouth) of the first electromagnetic direction valve 31 is connected with system pressure oil oil circuit 71; Its 3rd interface (T mouth) is then connected with the entrance of electromagnetic relief valve 4 by an one-way valve 8.A rodless cavity access in parallel rodless cavity oil circuit 22 respectively of four flanging oil cylinders 11, this rodless cavity oil circuit 22 is connected with the first interface (A mouth) of the second electromagnetic direction valve 32.Second interface (P mouth) of the second electromagnetic direction valve 32 is connected with system pressure oil oil circuit 71; Its 3rd interface (T mouth) is then connected with the entrance of electromagnetic relief valve 4.The outlet of electromagnetic relief valve 4 is connected with system oil return oil circuit 72.The entrance of two-way relief valve 6 is connected with rod chamber oil circuit 21 and rodless cavity oil circuit 22 respectively, and its outlet is connected with system oil return oil circuit 72.
