Abstract
The hydraulic loop for ten thousand ton hydraulic press operation system includes oil cylinders, conic valves and two-position three way high speed solenoid valves, and has one three-position four way digital valve comprising 4 conic valves and 2 two-position three way high speed solenoid valves. The conic valves act as the main control valves, the high speed solenoid valve as the fore running valve, and the conic valves are controlled to open or close via the control of high speed solenoid valves. The high speed solenoid valves are controlled with industrial control computer to realize digital control. The fore running valve may have its oil supplying pressure from autonomous loop or other pressure source. The present invention realizes the digital design of the hydraulic loop for ten thousand ton hydraulic press operation system and has raised reliability, operation performance, automation level and control precision of the operation system.
Description
Technical field
The present invention relates to a kind of ton water hydraulic press that is used for material pressure processing, particularly relate to hydraulic loop of ten thousand hydraulic press operation system.
Background technology
Existing hydraulic loop of ten thousand hydraulic press operation system generally adopts 3-position 4-way magnetic slide valve control servo-cylinder, and the 3-position 4-way magnetic slide valve has the hydraulic oil viscosity sensitivity, easily reveal the wearing and tearing back, shortcomings such as low-response cause control system can not accurately realize handling requirement after use a period of time.Existing control system adopts manually control and relay control, and automatization level is not high, and control accuracy is low, and control system is arranged scattered, is unfavorable for safeguarding and maintenance.
Summary of the invention
In order to alleviate operator's labour intensity, improve reliability, navigability, automatization level and the control accuracy of ton water hydraulic press control system, the invention provides a kind of control system hydraulic circuit that adopts digital valve.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of hydraulic loop of ten thousand hydraulic press operation system comprises oil cylinder, cone valve, the two-position three way high-speed switch electromagnetic valve, wherein, adopt 4 cone valves and 2 two-position three way high-speed switch electromagnetic valves to constitute a digital valve with various 3-position 4-way meta functions, this digital valve is to connect like this: cone valve V2, the pressure oil of the oil-in of V3 and hydraulic system major loop communicates, cone valve V1, oil-in and the fuel tank of V4 communicate, cone valve V1, the oil-out of V2 communicates as control mouthful A, cone valve V3, the oil-out of V4 communicate as control mouthful B, and cone valve is as main control valve, high-speed switch electromagnetic valve is as pilot-actuated valve, the opening and closing of the switch control cone valve by the control high-speed switch electromagnetic valve adopt industrial computer that high-speed switch electromagnetic valve is driven, and realize digital control.The charge oil pressure of pilot valve can draw from major loop, also can provide by other pressure sources.
The present invention has realized the design of hydraulic loop of ten thousand hydraulic press operation system numeral, has alleviated operator's labour intensity, has improved reliability, navigability, automatization level and the control accuracy of ton water hydraulic press control system.
Description of drawings
Fig. 1: the digital loop schematic diagram that adopts digital valve control.
The specific embodiment
Hydraulic loop of ten thousand hydraulic press operation system as shown in Figure 1, comprises oil cylinder 1, cone valve 2, two-position three way high-speed switch electromagnetic valve 3, the concrete course of work is: when high-speed switch electromagnetic valve D1 get electric, during the D2 dead electricity, the A mouth communicates with major loop pressure oil, and the B mouth communicates with fuel tank, and oil cylinder moves to right; When high-speed switch electromagnetic valve D1 dead electricity, D2 gets when electric, and the A mouth communicates with fuel tank, and the B mouth communicates with major loop pressure oil, and oil cylinder moves to left; When D1 and D2 get when electric, oil cylinder is in quick condition; As D1 and D2 all during dead electricity, oil cylinder is locked.
The control of high-speed switch electromagnetic valve D1 and D2 is directly controlled by industrial computer, realizes the digital control of hydraulic circuit.
