Three Roller Rolling Machine,Plate Bending Machine,Plate Roller Machine

Upper Roller Universal Plate Rolling Machine
The basic working principle for the upper roller universal plate rolling machine is to curve and roll. Rotating bending deformation is the core working procedure. This three roller rolling machine can be used for rolling the certain plates into the form of drum and arc. This plate bending machine can be used in petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy...

Curve Down 3 Roller Plate Rolling Machine
Curve down three roller rolling machine is also known as arc down-adjusting 3-roller rolling equipment. This plate bending machine 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...

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.

Composition

Compared with bronze bushings, spherical roller bearings of this three roller rolling machine can reduce friction and save 25% to 30% available energy.
The roll maintains a mechanical parallelism through our exclusive torsion bar system. It allows three roller plate bending machine to be adjusted to its full conical tilt.
All three rolls are independently driven by planetary gear drives. This can eliminate complicated transmission systems that are not energy efficient.

Features of Three Roller Rolling Machine

The upper roll on 3-roll plate bending machine is fixed. The two ends of upper roll are controlled by PLC. The two lower roll can move up and down in arc way around fixed roller. It can finish pre-bending and rolling by feeding once.
The three rollers are driving rollers. They can prevent skidding while rolling thin steel plates.
Three roller rolling machine is controlled by micro-machine and has digital display.
Compared with four roller plate bending machine, the structure of three roller plate rolling machine is compact and multiple. It is economical and practical for rolling thin and medium plates.
It features clear and precise operation, high efficiency, reliability and competitiveness.

Specification
Among different plate bending machines, three roller plate rolling machine possesses the maximum structure and driving modes. The structure, price and application of three roller rolling machine will be different owing to the roller position change.

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.
