W12-30X3000mm 4-roller plate roller machine design with CE
Four Roller Plate Rolling Machine. It wide used in the manufacture
of pressure vessels, machinery, hydropower, construction and other
industries of the barrel body per-bending, roll round, and also
gave a function of checking circle and leveling.
The top roller driven by hydraulic motor. Through the friction
between the metal plate and the top roller to drive the bottp,
roller and side roller rotate. And supply the torque for bending
plate. The botto, roller, side roller move along with an arc. The
bottom roller rising to clamp the plate and the side roller title
up to pre-bend the end of the plate.
The main character of the equipment
1. The 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
2. 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.
3. Our working roller side gear use ball gear, small in friction
and reduce the active power lose and save the energe.
4. 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
5. 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.
6. 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.
7. 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.
8. High-voltage parts use SUZHOU electronic, long working lifetime
and less fault.
9. The hydraulic valve in the hydraulic system use Taiwan brand,
the valve is casting runner , large oil flow ,small resistance,
less heat and reliable.
10. 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
11. 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.
12. The dumping gear will force on the dumping hydro-cylinder, the
head can incline and stand-up, convenient for take-off the working
13. The end of the working roller has balance equipment which will
be responsible for the working roller balance when the dumping gear
CNC control system
1. Special bending aircraft, numerical control.
2. HMI (human machine interface), intelligent operation.
3. Self-compensating, single operate, high efficiency, safe and
4. Many models for choice, economic numerical control model, TC
computerized numerical control.
Working roller is the main part of the machine, and the material
for four rollers are 42CrMo ,and done strictly industrial standard
needs for the working roller to guarantee the mechanical
The basement and the shaft if the main structure of the machine
through welded treatment, and strictly done through annealing
treatment to avoid inner-stress and ensure enough rigidity and
intensity and guarantee the normal working when full-loaded.
The upper-roller is main drive roller, the driver force is got by a
reducer through a connection to motor for rolling of the working
roller. In the shaft of this motor, there are brake apparatus to
make sure the precision position when rolling and prebending. The
full machine has enough intensity and rigidity, main parts of force
has keys to be reliable connected, easy for maintenance.
The bottom roller and two side roller’s up-and-down movement is
drive by the hydro-cylinders in two sides. The gear in two side use
self-aligning roller bearing, synchronization in movement, and
controlled by computer; The dumping side of the upper roller has
the dumping hydro-cylinder, the end of upper roller has the balance
equipment for convenient take-off the roller cylinder and working
