W11-8x3200mm Manual Sheet Metal 3 rolls Rolling Pipe Bending
3-roller symmetrical plate rolling machine Mechanical 3-roller
symmetrical plate rolling machine, Thread rolling machine, Metal
The machine widely used in petroleum, chemical industry, cement,
boiler, shipbuilding, aviation, water conservancy, power
transmission towers and other machinery and equipment. Its working
principle is rotating bending deformation. For the upper roller can
be moved no matter up and down, but also horizontally, so no need
additional press or equipment, can realize bending, as well as
correction of the workpiece.
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.
CNC Control system
1. It is controlled, in entry-level, by a user-friendly CNC, to
roll parts in automatic mode. More powerful DAVI CNCs (the most
advanced in the industry, until those selected by NASA), are
self-programmable, without the need of experienced operators.
2. HMI (human machine interface), intelligent
operation.Self-compensating, single operate, high efficiency, safe
3. 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
Upper roll device
The up roller gear drive from the main for turning, the ends of the
SP-1 bearing support, drive-side through the flat key, off the main
drive gear and connect the device to transfer torque, tip-side with
the protection of Steel .
The material of the up roller is 42CrMo, heat hardening is
Down roller device:
Down roller supports under the bearing, the bearing housings on
both sides of the rack mounted inside the track, the bottom of the
piston and cylinder connected. Bearing in the liquid under pressure
can rise and fall along the rail, according to the size of the
thrust rod, steel plate under the roller clamping force required by
the hydraulic system pressure control valve be adjusted.Addition of
the down lower rollers can roll adjustment, improve the accuracy of
product under the same material heat treatment hardening is
