Hydraulic Roller Bender, Steel Tube Rolling Machine, Pipe Rolling Machine
The 4 roll plate rolling machine has double pre-bending function for plate edge, and can bend roll the plate one time without any thing re-rolling with combined procedure or prebending and bending roll into shape.
The upper and bottom roller are the main drive rolls, the down roller and two side rolls up-and-down movement is controlled by hydraulic drive. The up-and-down displacement of the down and side rollers are controlled by computer.
Automatic leveling, digital display by screen , high synchronization precision ±0.2mm. Turnover bearing body dumping and reset is done through hydraulic transmission.
The upper roll end has balance equipment to be convenient take of the rolled cylinder and working pieces.There are moveable independent operation table for easy moveable operation.
This Advanced Design Has The Following Benefits Such As:
(1) Plate is introduced horizontally (and not tilted as on the three roll double pinch)
(2) Plate is squared instantly against the back roll (reducing risk of a mis-matched end condition of the part)
(3) Requires space only on one side of the machine, where the plate is introduced to the machine
(4) Greatly reduced flat-end (due to better pre-bending) thanks to the clamping roll that can take the edge to the precise tangent points of the top and bottom rolls
(5) It is the fastest machine to roll a can, as it would require only one position for each side bending roll
(6) The entire cylinder can be finished in only one pass (within a suitable capacity), including pre-bending of the edges
* No need to pre-bend both ends before starting to roll the entire cylinder, as required with a 3 roll
* No need to remove, turn and re-insert the plate as on a 3 roll single pinch
(7) The four roll could be even 50-80% faster and more productive than any style three roll
(8) The most suitable for CNC operation, as the plate is under a better control, clamped between the top and bottom rolls, until the part is finished
The Four Roll Design Is Recommend For Clients Who:
1. Wish to operate through CNC, with less dependence on operator skills
2. Look for more steady quality of the rolled products.
3. Look for high productivity, and increased profits.
4. Require good accuracy and quality improvements.
5. Need handling equipment for larger plates, who are also concerned for production or safety reasons.
6. Are new to plate rolling, as it is the easiest plate roll to operate.

1. Sheet rolling process allows operations such as punching, welding, and notching to be performed in-line. It provides an excellent pre-bending function on the processed components making the process more efficient.
2. The rollers have the ability to process a whole cylindrical metal body by rolling once.
3. Sheet rolling processes can work with a variety of metal sheets across a range of strength, corrosion-resistance, conductivity, and thickness. Practically, almost any material can be rolled as per the desired application.
4. Rolling allows for a high degree of flexibility. The components obtained from a pair of rollers can be of varying length or shape as required. In addition to this, the process gives better dimensional control and repeatability, minimizing any problems due to tolerance build-up of metal material.
1. Extremely robust structure machined with CNC control machines
2. Two hydraulic motors coupled to planetary gear units for the rotation of the two central rolls
3. Hardened rolls / Hardened and polished rolls
4. Separate control desk on wheels
5. Hydraulic opening of shoulder by control desk
6. Hydraulic inclination of lateral rolls for conical bending directly from control desk
7. Numerical control for automatic production
8. Movements of rolls on swing guides to reduce flat part
9. It can be used to roll tubes, tube segments, rounded boxes, ovals or other shapes.
10. Rolls rotation on high resistance selfaligning bearings
11. Rolls Cambering: know how variable cambering to avoid reel and barrel effect to increase bending performance and precision
(1) What is roller bending machine?
Rolling is the process of shaping metals into a finished or semi-finished form upon the application of rollers. The sheet metal is passed between one or more pairs of rollers to reduce and maintain the thickness of the material. Temperature plays a key role in the process as rolling can be done both hot or cold.
A gap is maintained between the pair of rollers running in the opposite direction in which the metal sheet of specific thickness is passed. Upon complete application, the metal sheet is increased in length (absolute elongation) and molded-in specific shape as per the requirement.
(2) What are the specific categories of your products?
We have main 3 kinds of roll bending machine, Mechanical 3 roller, hydraulic 3 roller with prebending and hydraulic 4 roller with pre bending.
(3) What we can do?
1. We have different CNC and hydraulic press brakes available, suitable to serve your specific job needs. all range of bending force from 40tons to 1200tons , and width from 1600mm to 12meters
2. Material processing machines include plate rolling. we can offers 12meters wide by 25mm thick plate rolling capabilities. Whether you need 1 off custom rolled cylinders or mass production - Huaxi has you covered.
3. Here we offer a full range of hydraulic metal shearing machine. Our machines allows processing of material up to 25mm thick and 6meters wide. Metal shearing for simple shapes not requiring plasma cutting.
We proudly serve fabricators in the pressure vessel, heat exchanger, boiler, military, heavy equipment, and other industries. Some of the common applications for light and heavy plate rolled steel includes: Circular Tank Walls, Pressure Vessel Shells, Boiler Shells, Piping, and Storage Tanks.
