Embodiment
Below in conjunction with drawings and Examples the present invention is described further.
As shown in Figure 1, the utility model provides the automatic control system of the series flow control valve in a kind of reinforced bar stretching machine combination brake switch and proporting, comprises pressure transducer, central processing unit (CPU) and hydraulic pressure combination valve activator; It is characterized in that: the output terminal of described pressure transducer links to each other with central processing unit (CPU), and the output terminal of described central processing unit (CPU) is provided with the signaling line in order to control band hydraulic pressure combination brake switch and proporting valve driving mechanism; Described signaling line is the guide line of control series flow control valve driving mechanism.
In preferred embodiment of the present utility model, described central control unit output terminal also is provided with the guide line in order to the 3-position 4-way combination brake switch and proporting control mechanism of control cylinder action direction; Above-mentioned 3-position 4-way combination brake switch and proporting control mechanism and described series flow control valve driving mechanism all are the mechanisms by Electric Machine Control, and its motor transmission shaft output terminal is provided with the coupling that links to each other with the transmission shaft of the rotary drive mechanism of valve; As shown in Figure 2, after motor 5 was received the signal of central processing unit (CPU) output, rotating joint 4 drove stop valve 1 and selector valve 6 actions, thus the working state of control oil cylinder.Equally, series flow control valve also is to be controlled by central processing unit (CPU) like this.
When system works, import a certain prestressed setting value, central processing unit (CPU) makes hydraulic pressure installation be in tensile state, makes series flow control valve be in the state of fastening simultaneously.When prestressing force was risen near setting value by stretch-draw, central processing unit (CPU) sent signal, and the motor action that is connected with series flow control valve of control stops after series flow control valve opened to a certain aperture (look the setting value difference, the aperture size is also different).Though this moment, selector valve also was in the stretch-draw position, because series flow control valve is opened, tensioning speed is zero or is negative.Prestressing force no longer rises.Central processing unit (CPU) judges that through the signal of pressure transducer input prestressing force does not also reach setting value subsequently, therefore sends signal, allows the reversing motion of series flow control valve motor, and series flow control valve is turned down gradually.Along with turning down of series flow control valve, tensioning speed rises gradually, and prestressing force also rises thereupon.When prestress value reached setting value, central processing unit (CPU) sent signal, and the series flow control valve motor is stopped.If after this prestressing force still continues to rise and exceeds setting value, central processing unit (CPU) then can send signal, and motor is left series flow control valve greatly once more.If prestressing force drops to less than setting value, central processing unit (CPU) then can make motor that series flow control valve is turned down again.At last, prestressing force in the tolerance range of this setting value, be maintained constant (series flow control valve stops at the aperture place of this setting value correspondence).Thereby the factor of the prestressing force fluctuation that the leakage because of combination brake switch and proporting causes is overcome, reach the prestressed purpose of accurate control.
What deserves to be mentioned is that described motor can be: AC induction motor, direct current generator, stepper motor, actuating motor etc.
Please continue referring to Fig. 1, the input end of described central processing unit (CPU) also is provided with the touch screen that is used for man-machine exchange.
Described central processing unit (CPU) carries out bidirectional data interaction by wireless data chain communication device and central control computer, realizes data display, record, report generation, preservation, printing, and control command is sent.
The utility model has following advantage:
Effectively overcome the prestressed fluctuation that the leakage because of combination brake switch and proporting causes, reached the prestressed purpose of accurate control;
Whether record is true, has avoided the imitation behavior of manual record, operate against regulations from writing down to find simultaneously;
Easy and simple to handle, the complicated manual operation of having forgone, labor intensity reduces, and mental burden alleviates; Realized automation mechanized operation;
Can enhance productivity to a certain extent;
But the record long preservation is convenient to inquiry, is reviewed;
Because prestressed setting value is to calculate by NBS, so, the quality problems of experimental material and Component indirectly;
By intellectualized reconstruction, make original manual equipment upgrade to automation equipment.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of this utility model.
