One limiting source and the second limiting source, the first limiting source are located at the two of hydraulic cylinder range distance respectively with the second limiting source
End, the encoder are mounted on and cut on vehicle, and the first limiting source, the second limiting source and encoder access control cabinet.
Preferably, further technical solution is：The control system further includes proportioning valve, and the proportioning valve is mounted on
On the hydraulic pipeline of hydraulic cylinder, the proportioning valve also accesses control cabinet.
Further technical solution is：The control cabinet be equipped with automatically with manual mode control device and hydraulic pressure
The stretching of cylinder and retraction control device.
Further technical solution is：The collection terminal of the encoder is in contact with the gear shaft cut on vehicle.
Further technical solution is：Described cut is equipped with burning torch on vehicle, and the vehicle that cuts is mounted on translational frame

Compared with prior art, one of the beneficial effects of the utility model are：Use ratio regulating valve can more smoothly
The supply amount of hydraulic oil is controlled, it is small to the impact force for cutting roller-way translational frame, oil cylinder and oil circuit, effectively prevent cutting process
Middle translational frame easily loosens, oil leak and roller-way dry slag, the generation for the accidents such as being hurt, greatly reduce equipment failure rate and repair
Cost；Simultaneously the utility model provide the one kind changed cut roller-way translate electrohydraulic control system it is simple in structure, can not only be used in
Continuous casting cuts translation roller-way, other need the production technology of the electro-hydraulic speed of Precise Control of Oil cylinder also can be applicable in, and have a wide range of application
It is wealthy.
Description of the drawings
Fig. 1 is the structure diagram for illustrating the utility model one embodiment；
In figure, 1 be encoder, 2 be the first limiting source, 3 be the second limiting source, 4 be hydraulic cylinder, 5 be burning torch, 6 for cut vehicle,
7 be translational frame.
Specific embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings.
Roller-way translation electrohydraulic control system, the control are cut refering to what is shown in Fig. 1, one embodiment of the utility model is one kind
System processed includes position detecting device, and position detecting device includes translational frame protective position and encoder 1, aforementioned location detection
Device includes the first limiting source 2 and second and limits source 3, and the first limiting source 2 and second limits source 3 and is located at hydraulic cylinder 4 respectively
The both ends of range distance；It cuts on vehicle in addition, aforementioned encoder 1 is mounted on, then limits the first limiting source 2, second
Control cabinet is accessed in source 3 with encoder 1.The first limiting source 2 and the second limiting source 3 just as mentioned previously is not greater than hydraulic pressure
The shift motion of cylinder, aforementioned first limiting source 2 can prevent hydraulic cylinder from excessively stretching out and closing oil cylinder oil inlet, and the second limiting source 3 is
Prevent hydraulic cylinder from excessively retracting and closing the effect of oil cylinder oil inlet, so as to which oil cylinder be enable to be moved back and forth between limiting 1 and limiting 2
Roller is kept away to realize；And it is fixed due to cutting vehicle and burning torch in the position in casting direction, so encoder only needs to be fixed on
Cut the position that just can detect burning torch on vehicle.
More particularly, Set scale valve is also needed in above-mentioned control system, which is mounted on hydraulic cylinder 4
On hydraulic pipeline, and the proportioning valve also needs access control cabinet.The principle of aforementioned ratio valve is valve mainly by electromagnetic force and bullet
Spring force controls the position of valve core, to reach control valve port size, so as to controlling flow（Certain pressure can also control）.Ratio is changed
Control is realized on amplification board to output a signal to the PLC module with analog output to valve.Proportional reversing valve can select
With voltage or current control, current mode is usually 4-20mA, and voltage-type is 0-10V, can be straight by the module of PLC
It connects to output a signal on amplification board and be controlled.
In the present embodiment, use ratio regulating valve can more smoothly control the supply amount of hydraulic oil, to cutting roller-way
The impact force of translational frame, oil cylinder and oil circuit is small, effectively prevents that translational frame in cutting process easily loosens, oil leak and roller-way are glued
Slag, the generation for the accidents such as being hurt, greatly reduce equipment failure rate and maintenance cost.
Another embodiment according to the present utility model keeps away roller manually to realize, roller is protected not cut bad, can also be above-mentioned
On control cabinet set one automatically with the stretching of manual mode control device and a hydraulic cylinder 4 and retraction control device.And
And the collection terminal of encoder 1 need to be in contact with cutting the gear shaft on vehicle 6；So as to which encoder is rotated by the shaft coupling of gear, tooth
Wheel can only in fixed gear grooved gear motion, so as to record the position of the movement of burning torch at this time, controlled automatically by computer
System calculates keeps away roller to realize.Further, aforementioned cut is equipped with burning torch 5 on vehicle, and cuts the side that vehicle is mounted on translational frame 7,
The output terminal power connector of translational frame 7 and hydraulic cylinder 4.
Refering to what is shown in Fig. 1, the utility model is in actual use, the principle realized is as follows：When cutting gun 5 is close to roller
Before original position during 50mm, send out translation signal, translational frame 7 pulls beginning to the direction movement of casting stream from hydraulic cylinder 4, when burning torch 5 again
Before the secondary original position close to roller during 50mm, reset signal is sent out, translational frame is pulled from hydraulic cylinder to be started to casting stream negative direction direction
It is mobile.It so moves in circles, until steel billet is cut off.Translational frame contacts when being moved forward and backward along casting stream direction with the limiting at both ends
To reduce translational energy.
Than that described above, it is also necessary to which explanation is " one embodiment " spoken of in the present specification, " another implementation
Example ", " embodiment " etc. refer to that the specific features, structure or the feature that combine embodiment description are included in the application summary
