The core features of the two-roller plate rolling machine are mainly reflected in the following aspects: 1. Structural characteristics Simple and compact Adopting a two-roller structure (the upper roller is a steel roller, and the lower roller is a steel roller core with an elastic layer), the number of rollers is minimal, and the mechanical complexity is low; Elastic layer design The high elastic composite material of the lower roller makes the plate force uniform, reduces the roller deflection, and avoids surface scratches. 2. Production efficiency One-time forming No need to pre-bend the plate end, continuous bending and forming can be completed directly, shortening the processing cycle; High-speed processing The processing cycle of a single finished product can be shortened to 30 seconds, which is especially suitable for mass production of thin plates. 3. Processing accuracy No residual straight edge The plate is bent over the entire length, reducing the trimming process, and the finished product has accurate roundness; High dimensional stability Strict tolerance control, smooth and flat surface, suitable for high-precision parts (such as automobile exhaust pipes, thin-walled pipes, etc.). 4. Scope of application Applicable materials‌ Mostly used for rolling of metal thin plates such as carbon steel and aluminum plates (usually ≤6mm, carbon steel ≤5mm); Applicable fields‌ Covering automobile manufacturing, fire-fighting equipment, solar water heaters, ventilation ducts and other fields, especially suitable for small-diameter workpieces (diameter ≤1300mm). 5. Automation capability Intelligent control‌ Support PLC control of the whole machine operation, integrating automatic loading, rolling and unloading processes to reduce manual intervention; CNC compatibility‌ The operation interface is friendly and easy to integrate with the production line to realize CNC production. 6. Limitations Thickness limit‌: Not suitable for processing thick plates (generally carbon steel thickness >5mm); Poor adaptability to small batch production‌: The roller needs to be replaced frequently, affecting processing flexibility.

Features of Four-roller Plate Rolling Machine ‌1. High-precision forming‌ The four rollers work together to precisely control the curvature radius and shape of the plate, achieving a forming effect that is highly consistent with the design drawings18. ‌2.

Multi-function and strong adaptability‌ Supports rolling of round, arc, conical and special-shaped workpieces, and is suitable for plates of different thicknesses (as thin as metal sheets and as thick as alloy plates) and materials (carbon steel, stainless steel, aluminum alloy, etc.)46. ‌4. Automation and stability‌ Adopting PLC control, touch screen interface and hydraulic transmission technology, it realizes automatic leveling and displacement control, and the structure is sturdy and durable, with strong pressure resistance37. ‌5. High processing efficiency‌ The multi-roller continuous rolling design supports one-time pre-bending and rolling, reduces turning operations, and improves production efficiency

The characteristics of the four-roller plate rolling machine mainly include high forming accuracy, wide range of applications, flexible and convenient operation, stable and durable structure and some other special design advantages. 1. High forming accuracy: The four-roller plate rolling machine can achieve delicate adjustment of the curvature radius of the plate by precisely controlling the coordinated operation of the four rolling rollers, ensuring that the workpiece fits perfectly with the design drawings, showing extremely high forming accuracy. 2. Wide range of applications: The four-roller plate rolling machine is never picky about the thickness and material of the plate. Whether it is thin metal sheets or heavy alloy plates, even common materials such as ordinary carbon steel, stainless steel, and aluminum alloy, it can be rolled. 3. Flexible and convenient operation: The design of the four-roller plate rolling machine fully considers the humanized needs. The operator only needs to gently adjust the parameters to quickly respond to the rolling needs of workpieces with different shapes, and realize an efficient and accurate rolling process. 4. Stable and durable structure: The overall structure of the four-roller plate rolling machine is rigorously designed. The four rollers and their supporting components, transmission mechanisms, etc. are carefully laid out and strengthened to ensure that they can remain stable even in the face of huge forces during the rolling process, ensuring the smooth progress of the rolling operation and the quality of the product. 5. Other special design advantages: such as the pre-bending function of the plate end, small remaining straight edge, and high work efficiency.

Our new 4-roller line offers many advantages. It is the easiest to use hydraulic press brake, thanks to the ability to clamp the plate between two motorized center rollers, pre-bend at the ends, and bend in one direction and through the entire body in one pass. Due to the constant squeezing of the center roller, the board remains square without slipping during pre-bending and bending cycles. This makes our 4-roller machines ideally suited to be controlled by NC or CNC. This machine is reliable and effective. The parallelism of the side rollers is controlled by a torsion bar system attached to both ends of the side rollers, eliminating the disadvantages of additional encoders and special hydraulic balancing valves. The two center rollers are driven by hydraulic motors and efficient planetary gearboxes coupled directly to the rollers. The MG solution assembles the rollers on sealed bearings without auxiliary parts, which reduces the dispersion of applied forces caused by friction of various components (commonly used in synchronization systems of other press brakes). The side rollers move up and down on planetary oscillating guides: the perfect geometry eliminates the disadvantages of linear gears. This allows us to have hydraulic pumps with lower flow motors, thus saving energy.
