Abstract
The utility model discloses a return single pump control system of a hexahedral top press, which comprises working cylinders and an oil supply pump. Oil outlet pipelines of the oil supply pump are divided into two paths; one path is connected with rear cavities of the working cylinders by connecting a two-position four-way electromagnetic reversing valve and a two-position two-way electromagnetic reversing valve; the other path is connected with a three-position four-way reversing electromagnetic valve; the three-position four-way reversing electromagnetic valve is divided into two passages; a first passage is connected with front cavities of the working cylinders; a second passage is connected with the rear cavities of the working cylinders by super-pressure hydraulic control check valves; and lower openings of the super-pressure hydraulic control check valves are connected with the first passage. Based on the condition that the primary release pressure and the quick return pressure of the hexahedral top press are the same (the pressures are respectively 8 MPa), a hydraulic control pump is directly reduced; one oil supply pump completes the work of the hydraulic control pump and the oil supply pump; the structure is simple, the input cost is low; failure spots are reduced; and the failure rate and the equipment maintenance rate are decreased greatly.
Description
Technical field
The utility model belongs to the technical field of hydraulic of synthetic diamond cubic hinge press, the single pump control system of particularly a kind of cubic hinge press backhaul.
Background technique
At present, the hydraulic system backhaul of synthetic diamond cubic hinge press comprises a release and two steps of quick return: during a release, and the hydraulic control pump work, its working pressure is 8MPa, hydraulic oil flows back to fuel tank by solenoid directional control valve and realizes release; During quick return, oil feed pump work, its working pressure is 8MPa, and hydraulic oil promotes piston by the ante-chamber that solenoid directional control valve enters six clutch release slave cylinders, and back cavity hydraulic oil is opened simultaneously by the ultrahigh pressure Pilot operated check valve, makes hydraulic oil get back to fuel tank and realizes backhaul.Above-mentioned hydraulic system backhaul needs hydraulic control pump and the work of oil feed pump two pumps, the system design complexity, and input cost is big, and the fault point is many, device maintenance rate height.
The model utility content
The purpose of this utility model is at above-mentioned deficiency, provides a kind of cubic hinge press backhaul simple in structure, that input cost is low and rate of fault is low single pump control system.
For achieving the above object, the technical solution of the utility model is: the single pump control system of a kind of cubic hinge press backhaul, comprise clutch release slave cylinder and oil feed pump, the fuel-displaced pipeline of oil feed pump is divided into two-way, lead up to and connect two four-way electromagnetic reversing valves, the 2/2-way solenoid directional control valve links to each other with the clutch release slave cylinder back cavity, another road connects the 3-position 4-way reversing solenoid valve, the 3-position 4-way reversing solenoid valve divides two paths, first path links to each other with the clutch release slave cylinder ante-chamber, alternate path links to each other with the clutch release slave cylinder back cavity by the ultrahigh pressure Pilot operated check valve, and the ultrahigh pressure Pilot operated check valve links to each other with first path for low mouthful.
The fuel-displaced pipeline of described oil feed pump is provided with one-way valve.
Branch's oil circuit of the fuel-displaced pipeline of described oil feed pump is provided with relief valve, throttle valve, is serially connected with pressure gauge behind the throttle valve.
Be connected to pressure regulator valve on the described 2/2-way solenoid directional control valve.
Compared with prior art, the utility model has the advantages that: based on a release of cubic hinge press identical with quick return pressure (being 8MPa), directly deduct the hydraulic control pump, be divided into two-way by the fuel-displaced pipeline of oil feed pump, lead up to and connect two four-way electromagnetic reversing valves, the 2/2-way solenoid directional control valve links to each other with the clutch release slave cylinder back cavity, another road connects the 3-position 4-way reversing solenoid valve, the 3-position 4-way reversing solenoid valve divides two paths, first path links to each other with the clutch release slave cylinder ante-chamber, alternate path links to each other with the clutch release slave cylinder back cavity by the ultrahigh pressure Pilot operated check valve, the ultrahigh pressure Pilot operated check valve links to each other with first path for low mouthful, an oil feed pump is finished the work of hydraulic control pump and oil feed pump two pumps, and is simple in structure, and input cost is low, reduced the fault point, rate of fault and device maintenance rate reduce greatly.
