Description of Four Roller Bending Machine:
The structure of this machine has four rollers, the upper roller is the key drive. Through the engagement between the gear of the moderator and the gear of the upper roller provides the plates bending with torque. The lower roller makes lifting movements, the hydraulic cylinder imposes a force on the piston to clamp roller sheet tightly. Moreover, there are side rollers on the side of down roller transmitting by screw nut turbine worm or hydraulic rod. The four roller bending machine can make plates both pre-bending end and round rolling.

1. This machine uses an unique synchronous structure and four-rollers veneer reeling machine with high precision and roundness. (The former type of sliding steering whose slides are easily abraded, so the precision and the quality of the machine will be affected.)
2. This machine is driven by a hydraulic motor. The four-roller veneer reeling machine is eco-friendly and energy-saving.

3. Straight edge is short, so the effect of pre-bending is more suitable for cones.   
4. The rolling process can be finished in one operation, including pre-bending of the two sides and the four-roller veneer reeling. This machine is easy to operate and only requires one worker.
5. Meanwhile, this machine has the function of automatic position adjustment and clamping so that the boards will not slide.
6. The four roller bending machine avoids overload and protects from hydraulic pressure.
7. This machine is abrading-proof, there's no need to lubricate it.
8. The diameter of roller is narrow, the four-roller bending machine can produce barrels of a diameter 1.1 times as small as the upper roller’s. While, bending-oriented linear slide can produce barrels of a diameter from 0.5 to 1.4 times as large as upper roller. )

Features of Four Roller Bending Machine:
1. This machine has a better ability to produce barrel with smaller diameters than ones produced by other machines of the same standard. Moreover, it is energy-saving, it consumes less electricity than most of our competitors' machines.  
2. Two kinds of rolling available: Asymmetric rolling and Symmetrical roll. So it can process forward bending and backward bending.
3. The operational program is easy to use, so anyone can operate it.
4. The upper roller can be designed according to its use, and side rolls are all main drive.  
Operating Principle of Four Roller Bending Machine:
The centre of down roller changes the curvity of making plate along the curve track; meanwhile, it also changes the distance between two down rollers. So it will not slide with the range from lamina to nominal thickness plate.
Use of the Four Roller Bending Machine:
1. This machine is a lower adjusting 4-roller coiling machine which is manufactured by employing European advanced structural design.
2. It widely uses in manufacturing cylinders in many fields, for example, petroleum, chemical industry, boiler, steel industry, machinofacture and others.
