The oil pump motor set is connected with the oil filter which is connected with the proportional overflow valve; the proportional overflow valve is connected with the three proportional reversing valves which are respectively connected with the proportional reducing valve; the pressure sensor is arranged between the proportional reducing valve and an oil cylinder; and the electric control system is respectively connected with the pressure sensor and the proportional reducing valve by a data wire. The pressure sensor is used to measure the pressure on a steel tube when each oil cylinder is jointed and pre-welded. The oil cylinder work is respectively controlled by the electric control system according to the feedback signal. The problems of the hard control caused by the manual operation of the operator and the high requirement on the experience of the operator are overcome.
Description
Technical field
The utility model belongs to technical field of hydraulic, particularly a kind of system that controls the oil pocket pressure on the machine tool motion component.
Background technique
At present, mostly the different size according to steel pipe adopts manual adjustment system pressure and oil cylinder working-pressure during the prewelding steel pipe, in the process of regulating, can accurately not adjust pressure, just with the empirical value adjustment, when the joint close welded tube, the size of pressure is difficult to control, when being everlasting joint close,, can not reach the effect of joint close when pressure is too small owing to pressure is adjusted excessive pipe deformation, the damage machine tool element of making, make steel pipe and can't weld, weld also not steady because the joint close gap length is inhomogeneous.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, a kind of variation that can adjust electric parameter according to the variation of steel pipe specification effectively and then adjust pressure is provided, reduce losses such as pipe deformation, guarantee the quality of production, improve manufacturing efficiency and output, effectively saved the tracking steel pipe servo-hydraulic system of the energy.
For solving above-mentioned technical problem, this superconducting magnet power supply adopts following technological scheme:
A kind of tracking steel pipe servo-hydraulic system, comprise proportional pressure control valve, Oil pump electrical machinery group, oil purifier, proportional reversing valve, proportional pressure-reducing valve, pressure transducer and electric control system, described Oil pump electrical machinery group connects oil purifier, oil purifier connects proportional pressure control valve, proportional pressure control valve connects three proportional reversing valves, proportional reversing valve is connected with proportional pressure-reducing valve respectively, between proportional pressure-reducing valve and the oil cylinder pressure transducer is set, electric control system connects with pressure transducer and proportional pressure-reducing valve respectively by datawire.
Beneficial effect of the present invention:
This system controls three oil cylinders respectively separately.On the oil pipe between proportional pressure-reducing valve and the oil cylinder, be equipped with pressure transducer, this pressure transducer is used for having measured each oil cylinder when joint close and prewelding, the pressure that steel tube place bears, control oil cylinder work according to feedback signal respectively by electric control system, changed and used its pressure of manually-operable in the past, the operator is difficult to control, the operator is required the experienced difficulty that waits, the more important thing is to enterprise and saved cost, reduced the unnecessary loss of enterprise, the output and the output value have been improved greatly, increased the income of enterprise, become in the past manually turn to automation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of as shown in Figure 1 tracking steel pipe servo-hydraulic system, it is characterized in that: comprise proportional pressure control valve 1, Oil pump electrical machinery group 2, oil purifier 3, proportional reversing valve 4, proportional pressure-reducing valve 5, pressure transducer 6 and electric control system 7, described Oil pump electrical machinery group 2 connects oil purifier 3, oil purifier 3 connects proportional pressure control valve 1, proportional pressure control valve 1 connects three proportional reversing valves 4, proportional reversing valve 4 is connected with proportional pressure-reducing valve 5 respectively, between proportional pressure-reducing valve 5 and the oil cylinder 8 pressure transducer 6 is set, electric control system 7 connects with pressure transducer 6 and proportional pressure-reducing valve 5 respectively by datawire.
The working procedure of this tracking steel pipe servo-hydraulic system is: start working under the driving of Oil pump electrical machinery group 2, the high pressure oil of Oil pump electrical machinery group 2 is after oil purifier 3 filters, through proportional pressure control valve 1 proportional reversing valve 4 of flowing through respectively, proportional pressure-reducing valve 5 enters in the oil cylinder, electric control system 7 input parameter resize ratio relief valve in advance makes system pressure certain, again according to the material of steel pipe and the specification of steel pipe, the relevant parameter adjustment proportional pressure-reducing valve 5 of electric control system 7 inputs makes steel tube surface in order to suitable pressure, reduce pipe deformation, thereby improve the stationarity of welding greatly.When steel pipe joint close with the welding different size the steel pipe process in, because the variation of steel pipe specification, the change of the parameter of electric control system input, the pressure of oil pocket is changing at any time, the pressure of oil cylinder is along with the pressure of steel tube place's carrying takes place by corresponding the variation, corresponding variation and unequal mutually also takes place in each in-oil cylinder oil pressure, at any time detect the variation of oil pocket pressure by the pressure transducer 6 at each oil cylinder place, by pressure transducer 6 feedback signals, electric system control system 7 receives the electrical signal that changes, control ratio subtracts pressure valve 5, the pressure that makes oil cylinder impose on steel pipe reaches the pressure of welded steel pipe, guarantee when welding pressure and the specification of steel pipe be complementary, changed and used its pressure of manually-operable in the past, the operator is difficult to control, the operator is required the experienced difficulty that waits, the more important thing is to enterprise and saved cost, reduce the unnecessary loss of enterprise, improved the output and the output value greatly, increased the income of enterprise, become in the past manually turn to automation.
