RAYMAX Plate Rolling Machine – Pinch Roll Design with Independent Speed Control for Anti-Slip Rolling

RAYMAX plate rolling machine uses a hydraulic pinch roll that grips the plate edge with adjustable pressure (up to 50 tons), preventing slippage when rolling high-strength steel plates. The two lower rolls have independent speed control, allowing one roll to run slightly faster than the other to compensate for plate asymmetry. This feature is critical for rolling conical sections and tapered cylinders. Maximum width 2500mm, thickness 20mm for Q345 steel. Digital readouts display roll position and bending radius. Applications include chute liners, conveyor drums, and irrigation pipes. RAYMAX includes a set of bending templates (different radii) and an operator’s manual with safety checklists in six languages.

Why choose us?

Economical Three-Roller Design for General Sheet Shaping

RAYMAX plate rolling machine offers the W11 mechanical three-roller plate rolling machine, mainly used for rounding off plates from 4mm to 40mm thickness and 1500mm to 4000mm in length. It is a very affordable and economical plate rolling machine, the best choice for general fabrication shops and maintenance departments. The three-roller initial pinch type handles plates with hydraulic or mechanical force to shape flat sheets into accurate cylinders, achieving straightness deviations below 0.5mm per meter. RAYMAX plate rolling machine is ideal for pressure vessels, pipelines, storage tanks, boilers, wind power towers, and tunnel arches. The hardened steel rolls (HRC 52-55) resist wear when rolling carbon steel, stainless steel, and aluminum. RAYMAX provides a digital bending calculator to generate rolling parameters from customer drawings, reducing setup time by 50%.

Four-Roller Hydraulic Model for Pre-Bending Without Flat Ends

RAYMAX four-roller plate rolling machine is suitable for bending work of sheet metal, capable of rolling round, arc, and tapered workpieces within a certain range. The four-roller design features a hydraulic pinch roll that grips the plate edge with adjustable pressure, preventing slippage when rolling high-strength steel plates. It has a pre-bending function at the end of the board, eliminating flat sections and reducing welding preparation time by up to 40%. This is critical for pressure vessel shells where consistent roundness is essential for butt welding. The four-roller configuration pre-bends both ends in a single pass, saving time and improving accuracy. Maximum rolling width 4000mm, thickness 60mm for mild steel. RAYMAX plate rolling machine is the preferred choice for pressure vessel fabricators, oil storage tank manufacturers, and penstock producers.

Digital Roll Position Display for Repeatable Production

RAYMAX plate rolling machine features digital displays showing real-time roll position and bending angle, allowing operators to record and reproduce settings for standard product families. The W11S plate rolling machine features hydraulic lifting, mechanical horizontal movement, and centralized electrical control, supporting pre-bending, rolling, and leveling operations while saving material. Optional NC system control provides advanced automation for high-volume production. A digital readout shows the distance between rolls, which correlates to bending radius. RAYMAX includes a bending radius calculator software that generates rolling parameters from input diameter, material, and thickness. This plate rolling machine is used by companies that produce standard product lines such as air receiver tanks, manhole shells, and wind tower sections, ensuring consistent quality across batches.

The working principle of a plate rolling machine is based on the concept of continuous three-point bending, where the metal plate is progressively deformed as it passes between rotating work rolls. In a standard three-roll symmetric plate rolling machine, the upper roll is positioned centrally between two lower rolls. The upper roll moves vertically, driven by hydraulic cylinders, to apply downward pressure on the plate, while the two lower rolls rotate, driven by a main reduction gearbox, to feed the plate through the machine. The plate undergoes multi-pass continuous bending, with the inner layer undergoing compression, the outer layer undergoing tension, and the central layer remaining in a neutral state. This permanent plastic deformation results in the plate being formed into a cylinder, cone, or portion thereof. The hydraulic system provides the immense force required for thick plate bending, with the upper roll moving vertically at the central symmetrical position of the two lower rollers. The bottom rollers are driven by gears and a worm reduction gearbox, with the top roll rotating in fixed positions and adjustable up and down by an electric proxy. In a four-roll hydraulic plate rolling machine, an additional side roll holds the sheet securely during forming, eliminating slippage and improving edge alignment. This design allows for pre-bending of plate edges without removing the plate from the machine, significantly reducing handling time and improving production efficiency. RAYMAX’s rolling machines are equipped with most advanced and peripherals technologies for more effectiveness, making them ideal for use in automotive, shipbuilding, power generation, and other industries. The rolling machines are made with high-grade material and go through rigid quality control to ensure that they can be treated as heavy-duty machines, providing extended years of reliability. RAYMAX rolling machines for sheet metal rolling are manufactured to international standards and have regional backup in different places, ensuring full support regardless of your location.

Frequently Asked Questions

What key functions does an ironworker machine combine?

An ironworker machine integrates punching, shearing, notching, and bending in a single setup. It can punch holes up to 32mm in diameter, shear 6-12mm steel plates, and achieve bending angles up to 135°, greatly reducing the need for separate machines.
RAYMAX shearing machines achieve cutting accuracy of ±0.05mm, which is 10 times faster and more precise than manual cutting methods, delivering clean, straight edges essential for automotive, aerospace, and construction applications.
Hydraulic press brakes offer greater control over pressure and speed, are quieter, and are better suited for thick or hard materials. They also tend to have longer service lives due to reduced mechanical strain.
A fiber laser cutter uses a fiber-optic-delivered laser beam (1064nm wavelength) focused into a 0.1mm spot to melt and vaporize metal materials, creating clean, accurate cuts for automotive, aviation, and shipbuilding industries.
