W11-16X2500mm 3 rolls small sheet roller bending machine made in
1. The machine adopts 3-roller symmetrical structure with the upper
roller moving vertically in the center between the two lower
rollers, which is achieved through the drive of the screw, the unt,
the worm and the lead screw.
2. The two lower rollers rotates, and provides the plate materials
with torque through the engagement of the output gear of the
moderator with the gear of the lower rollers.
3. adapted for bending metal plate into round, arc, and so on. Its
working principle is rotary bending deformation. This product is
widely used in chemical industry, Cement,shipbuilding, boiler,
aviation, water control project, Power Transmission Tower, metal
structure and the industry of making machinery.
1. The cylinder rolling is completed by the upper roller which
presses to the lower one and the mutual rolling.
2. The machine consists of the operation part and the transmission
part which are welded at the whole bottom pallet.
The operation part consists of left and right bearing housing, one
upper roller, two lower rollers, lifting gears and some
accessories. The lower roller is the main one, upper roller can be
adjusted at the height. The transmission part consists of the main
motor, speed-reducing motor and other accessories.

3. The lower roller is driven by the main motor through the main
reducer. The main reducer output shaft transmits to the two lower
rollers through a group of gear wheel. The roller driving direction
is switched by the main motor.
4. The elevation movement of the upper roller is realized by the
auxiliary motor through the auxiliary reducer, which drives worm
and worm wheel under the left and right roller bearing to move
automatically, makes the steel wire nut which is fixed on the worm
wheel rotating, and completed by up and down movement of ball
bearing screws accordingly.
5. The offloading device is used after the round cylinder have been
finished. Before leaving the left bearing seat, raises the upper
roller to standard height, and make the upper roller stop with
balance pull rod at the bottom of upper roller. Then draw out pin
shaft on the tilting bearing seat, overturn the tilting bearing
seat, then the coiled product can emerge from one end of the upper
6. The main components are: three 45 steel forged rollers, HRC3545,
support frame is welded, process after being welded, the lower
pallet is a welded part. Ball bearing screw and worm gear are 45
steel forged parts.
7. Electrical parts is adopted famous apparatus, steady
performance, durable, safe and reliable, operates conveniently.
Hydraulic system provides power to lift bottom and side rollers
through driving cylinders, also controls tilting cylinder up and
down. The hydraulic system works reliable with reasonable design.
In order to guarantee oil clean, system is equipped with oil
sucking & returning filters with high accuracy. The radial
quick joints particularly used in metallurgical & mining are
applied in the hydraulic pipes and valves to avoid leaking.
The main valves of the hydraulic system are the products of the
Taiwan Northman Co., Ltd. or abroad. Pump oil filters, motors and
seals are products of famous producers inland. All of them are
advanced performances and reliable quality. All hydraulic parts
have passed strict inspection and test to eliminate hidden trouble
System pipes with over load protection are well arranged to easily
operate and act flexible.
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
