Description
Spherical roller bearings are the main working part of three roller
rolling machine. These roller bearings are parallel. According to
the number of rollers, our company can provide two roller plate
bending machine, three roller plate roller machine, four roller
type and multi-roller rolling machines. According to the movement
of roller, the structure of this three roller plate rolling machine
is designed as hydraulic symmetrical up-adjusting type, the
cross-shape movement of top roll, horizontal down-adjusting type
and arc down-adjusting type. We also supply upper roller universal
rolling machine and curve down 3 roller plate bending machine.
Application
Three roller rolling machine can roll the work-piece in a wide
range, such as aluminum composite panel, pure aluminum plate,
stainless steel board and steel bar. With the help of
auxiliary equipment, this kind of plate roller machine can roll arc
work-piece. This 3-roll plate bending machine is the most
innovative machine in the market. It is especially suitable for the
heavy loading work of rolling thickness bar. Three roller
plate rolling machine can also roll very thick plates by increasing
the distance between the lower side rollers.
Comparison of Structure and Driving Mode of Three Roller Plate Rolling Machine
| Structure | Top Roll Movement | Driving Mode of Top Roll | Lower Roll Movement | Driving Mode of Lower Roll | Feature |
| Symmetrical Up-Adjusting Type | Up and down movement of the top roll | The top roll moves up and down. It rotates passively. | The location of the lower roll is fixed. | The lower roll, as the main drive, is driven by the motor, speed reducer and gear. | With simple structure, it can be pre-bending. |
| Cross-Shape Movement of Top Roll | Up and down movement and horizontal movement of the top roll | The top roll moves up and down. It rotates passively. | The location of the lower roll is fixed. | The lower roll, as the main drive, is driven by the motor, speed reducer and gear. | It is pre-bending. The small fuel tank features light weight and high center of gravity. It is applicable to small and medium-sized machines. |
| Horizontal Down-Adjusting Type | Up and down movement of the top roll | The top roll moves up and down driven by the fuel tank. It rotates driven by reducer and hydraulic motor. | The movement of the lower roll is horizontal. | The lower roll is moved horizontally by the cylinder drive. It rotates passively driven by hydraulic motor or speed reducer. | It is pre-bending. It can roll thinner work-piece and thick-walled cylinder work-piece. With a large fuel tank, it owns low center of gravity and heavy weight. It covers a wide range of applications. |
| Arc Down-Adjusting Type | The location of the upper roll is fixed. | The upper roll is fixed. It rotates driven by hydraulic motor reducer or chain drive. | The lower roller moves up and down around the centre axle. | Driven by the fuel tank, the lower roll moves up and down around the fixed central axle. It also rotates driven by motor and multistage gear. | It is pre-bending. It can roll thin-walled small diameter work-piece. With compact structure, it is more complex to operate. |
Description
The upper roller universal plate rolling machinery can be mainly
used for rolling the certain plates into the form of drum and arc.
The basic working principle for this plate bending machine is to
curve and roll. Rotating bending deformation is the core working
procedure. It can also be applied in petroleum, chemical industry,
cement, boiler, shipbuilding, aviation, water conservancy, power
transmission towers and other machineries.
Structure
The main structure of the upper roller universal plate rolling
machinery (upper roller universal plate bending machine) includes
upper roll, lower roll and horizontal movement mechanism,
supporting mechanism, main drive mechanism, left and right machine
frame, chassis and balance mechanism, hydraulic and electrical
control systems.
Advantages of Upper Roller Universal Plate Rolling Machinery
1. This plate bending machine can roll thin or thick plates with
high straightness.
2. It can finish the pre-bending, bending, curvature forming as
well as correction of the work piece.
3. The upper roller of this plate bending machine can move
horizontally and vertically so the auxiliary equipments are not
needed.
4. Upper roller universal plate rolling machinery features NC
control, high productivity, excellent product precision, integral
structure, safety and rich bending shapes.
5. The rear bending process can be used to eliminate curved toward
the front of the dorsal horn.
6. Smooth welding operation guarantees high welding quality of this
plate bending machine .

Description
Curve down 3 roller plate rolling machine is also known as arc
down-adjusting 3-roller rolling equipment. It has three rolls for
the whole drive roller. The planetary gear hydraulic motor provides
torque to roller plate. There is no mutual sliding between the work
piece and the basic roll. The roller is driven by hydraulic
cylinder to do arc up and down movement. This plate rolling
machine possesses self-aligning roller bearings. This arc
down-adjusting 3-roller rolling equipment has the advantage of
feeding without the aid of accessory devices. It is able to
complete the pre-deformation of both ends and carry out sheet metal
shaping. The main structure of this plate rolling machine includes
tip side of the rack, fixed side of the rack, work roll, drive,
hydraulic system, electrical control system and other components.
Features
The arc down-adjusting 3-roller rolling equipment features compact
structure, easy and reliable operation, easy maintenance and high
control accuracy. This plate rolling machine can lift the roller
device with digital display. Besides, it is more convenient to
disassemble or unload.
