    W12 Double Pinch 4 Roll Plate Bending Machine Sheet Bending Tools

    W12 Double Pinch 4 Roll Plate Bending Machine Sheet Bending Tools


    Description:


    The sheet rolling machine has pre-bending function for plate edge, and can bend roll

    the plate one time without any thing re-rolling with combined procedure or prebending

    and bending roll into shape. The upper roller is the main drive roll, the down roller and

    two side rollsup-and-down movement is controlled by hydraulic drive. The up-and-down

    displacementof the down and side rollers are controlled by computer. Automatic leveling,

    display by screen, high synchronization precision ±0.2MM.Turnover bearing body

    dumping and reset is done through hydraulic transmission. The upper roll end has

    balance equipment to be convenient take of the rolled cylinder and working pieces.

    There are moveable independent operation table for easy moveable operation. The

    machine has been equipped with security linked equipment. It is ideal bending roll

    machinefor all kinds of metal working industry like energy, transportation ,petroleum,

    chemical, shipping-building, boiler with high technology, full function, high precision and

    easy in operation character.

    The machine is equipped by four working rollers, left-right machine shaft, basement,

    cone rolling equipment, dumping parts, transmission part and relate sensor section,

    hydraulic system and electrical system


    Character:


    The rolling machine is computer-controlled four roller bending rolls machine with the

    pre-bending function. After the plate loaded, no need to change into another side edge

    for the prebending and rolling.

    The machine four rollers has been produced by forge, hardening and tempering treatment.

    HB220-260 with good mechanical properties, high rigidity, high in anti-abrasion, good for

    high-load working and long working lifetime.

    Our working roller side gear use ball gear, small in friction and reduce the active power lose

    and save the energe.

    The bottom roller and side rollers movement are controlled by computer. Automatic-leveling,

    digital display screen, the synchronization accuracy ±0.2MM, high in rolling precision and

    easy in operation.

    The machine down roller, side roller can do one-side inclining, and can make synchronization

    movement in inclined position for a better cone rolling working.

    The machine has moveable operation table for a convenient worker operation and the touch

    screen has the position for the three rollers, easy for you understand the position.

    The machine control system adopt Japan OMRON company intelligent PLC programmable

    control with fault diagnosis and operation fault intelligent judgment, the all parts inspection

    for the machine, logic treatment , power-off memory.

    High-voltage parts use SUZHOU electronic, long working lifetime and less fault.

    The hydraulic valve in the hydraulic system use Taiwan brand, the valve is casting runner ,

    large oil flow ,small resistance, less heat and reliable.

    The pipes in all hydraulic system use fast joint, new-technology used in metallurgical mines,

    in the connectors, there are reliable seal to ensure no leak out in the hydraulic system.

    The hydraulic system has absorption and return oil filter to ensure the clean of the hydraulic

    system. And also air filter to guarantee the hydro-cylinder normal absorption and water

    evaporation, and in the system there are double-way security protection equipment to ensure

    the system safe.

    The dumping gear will force on the dumping hydro-cylinder, the head can incline and stand-up,

    convenient for take-off the working pieces.

    The end of the working roller has balance equipment which will be responsible for the working

    roller balance when the dumping gear is working.

    Advantages:


    The 4 roll plate bending machine is the easiest one, thanks to a frame designed to satisfy every

    kind of needs. Advantages are various :

    1. Pre-bending is highly reduced because the material gets pinched by in between the two central rolls.

    2. Working can be made in one only pass, following the steps here below:

    • Squaring
    • Pre-bending
    • Bending
    • Closing pre-bending

    3. The plate is fed into the machine horizontally thanks to the support of the lower roll (B) with the

    side roll (D).

    4. The plate is squared thanks to the position that the side roll (C) takes.

    5. The space to the limit of the machine reduces to one side only, thanks to the possibility of squaring

    and bending in one only step.

    We advise a 4 roll plate bending machine :

    6. For a high and massive production

    7. For the possibility to control by NC

    8. For the possibility to make conical bendings


    Control System Function:


    To control the working roller synchronization movement automatially

    Control the bottom roller vertical movement synchronization, the synchronization

    precision is ±0.2MM.

    Control two side rollers synchronization movement,the synchronization precision is ±0.2MM.

    display real-time date and all rolling information and plate-rolling information.

    The bottom roller’s two side has real time date.

    The two sides of side rollers has real time date.

    control system has warning messenger to timely know what happened for convenient operation

    and maintenance.
