    6,Hydraulic pressure system

     

     

    General introduction

    Hydraulic system is fabricated according to national standard,industry standard and reasonable arrangement. We have considered high efficiency and saving energy, reduce the waste and heat source. The system is separated and connection point will use special sealing glue.Prohibit leakage. It is easy to maintenance.Hydraulic pressure pump is used high pressure oil pump, hydraulic pressure valve is used Yuci Youyan accumulated valve system. Testing pressure is 25MPa without leakage. The arrangement of pipeline is simple, less leakage and easy maintenance. To guarantee oil liquid clean, it is designed oil filter in oil mouth of oil pump. Pressure oil from oil pump can enter into pressure adjustable system.Then through valve lump, via diverting valve to oil cylinder.

    Hydraulic pressure system

    Hydraulic pressure system is composed of oil pump, valves, flow connection and hydraulic pressure parts etc.

    Hydraulic valve is used accumulated valve The arrangement of pipeline is simple and easy to maintenance and commissioning.

    The system is composed of three circuit, over pressure protection and pressure adjustable circuit, synchro circuit, speed circuit.

    Pressure adjustable circuit will adjust system work pressure by main spillage valve. System work pressure is 19.5MPa.

    Synchro circuit is synchronized to down roll, rising and falling of side roll.Adjust throttle valve up and down, Inspect it by movement sensor. Keep the synchro precision in ±0.05mm.

    Speed circuit shall control turnover, restore of side machine and adjust throttle speed of circuit of throttle valve.

    All protection.

    The rising and falling of down roller and side roller has designed pressure limit protection.

     

     

    7. Electric control system

     

     

    General introduction

    Electric control system is composed of electric control cabinet, operation control table. Controller will install in electric control cabinet.Display with screen digital.It is easy to operate. Main circuit use three phase 380V/50Hz AC power. NC control input circuit will use 24V DC power. Control circuit will use 220V/50Hz AC. Driving and hydraulic pressure pump station of main motor will provide the power.Main electric element will use famous brand in China. Fabricate it according to the national standard and the structure is reasonable with necessary safe and protection measurement.

    Control cabinet is designed all control button, indicating light, the programmed touch screen etc. During the rolling. Realize to monitor the work condition and operation control.

     

     

    All protection

     

     

    Motor will protect by the relevant breaker with short circuit of current and heat relay with overloaded protection.

    Down roller,the rising and falling of side roller shall have the relative limit switch as limit protection.

    Turnover and restore of cylinder has designed up and down limit switch for limit protection.

    The breaker of general power has shunt button machine. There is the button of emergency stop in operation table and turnover side frame to cut off the power in remote.

     

     

    All interlocks

     

     

    After turnover frame is restored, the rising and falling of down roller and side roller,rotation of up and down roller may go on(inspect it by limit switch of turnover frame.

    Trouble indication

    When main motor is overloaded, trouble indicating light will inform. When PLC is in trouble, indicting light will also form.

    Function of numerical screen

    The system of numerical screen can monitor the rolling process, numerical transmitting and power off memory. Human-computer interface is obvious in Chinese character.

    Function of real monitoring control

    Display up and down movement (Yg,Yf),lifting of side roller(X) of oil cylinder in the screen.

    Function of human-computer conversation

    Realize the editing, revision of work piece technical parameter with LCD screen through system input.

    Industry controller PLC can control according to two ends position of up roller. Guarantee the synchro precision. Resolution ratio of movement sensor is 0.05mm.

    It has the function of automatic diagnosis.

     

     

    Applications:

     

     

    • The structure is dependable, coinvent maintenance, up and down movement of bottom roller, rising and falling of side roller with digital display. The operation is coinvent and control accurately.
    • Up and down roller is driving roller. Up roller is fixed and down roller can rise and fall, clamp the steel plate. When When plate is clamped by up and down roller,up and down roll drives relatively. There will be friction between plate and work roller. Make plate move. The rising and falling of side roller will make plate bend.adjust the rising of side roller which can reach the requested arc or radius of curvature of round work pieces.Side roller is driven roller which depend on the friction between roller surface and steel plate.Make it drive.The rising and falling is driven y hydraulic pressure oil cylinder.
    • One end of turnover side machine frame is designed one turnover oil cylinder. After the rolling is finished, balance oil cylinder will work. Turnover oil cylinder will work also. After unload workpiece, turnover oil cylinder will work again and restore turnover side machine frame. One work circle is all finished.
