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.
