As modern metalworking equipment, four-roller plate rolling machines offer the following core features: High-precision control Utilizing a hydraulic motor drive and PLC control system, they achieve precise displacement adjustment and automatic leveling, resulting in significantly superior rolling accuracy compared to three-roller models. Select models are equipped with sensors and a touchscreen for real-time monitoring of processing parameters. Versatile rolling capabilities Supports single-load pre-bending and fully automatic rolling to form the plate, eliminating the need for reversing. Capable of processing round, curved, tapered, and special-shaped workpieces, with a minimum rolling diameter of up to 50 mm. Combined drive systems for the upper and lower rollers and hydraulic cylinders on the side rollers enable complex deformation control. Efficient and energy-efficient design The servo motor and hydraulic system optimize oil flow and power transmission efficiency, reducing energy consumption while increasing processing speed. Structural Advantages The four-roller layout (upper and lower main drive rollers + auxiliary rollers on both sides) is more stable than three-roller models, reducing the risk of plate collapse. Equipped with upper and lower support devices, large-diameter workpieces can be rolled without additional support. Operational Convenience The fully automatic CNC system supports programmable operation, and some models feature a one-touch rolling function, significantly reducing the need for manual intervention. Note: Although the four-roller plate rolling machine is more expensive, its comprehensive advantages in processing range, precision, and efficiency make it the preferred choice for demanding applications.

1. Core performance advantages ‌High one-time forming efficiency‌ Using the synergistic effect of the upper roller (steel roller) and the lower roller (elastic roller), the plate can be bent and formed by one pressurization, without the need for pre-bending process, significantly shortening the processing cycle, especially suitable for the continuous production of thin-walled pipes such as exhaust pipes14. ‌High precision and surface quality‌ The elastic layer of the lower roller is made of composite materials, with uniform stress distribution and small roller deflection, ensuring high geometric accuracy and smooth surface without scratches after forming, meeting the stringent requirements of exhaust pipes and other products for sealing and appearance14. ‌Dynamic adjustment capability‌ The upper and lower roller spacing and pressure are precisely adjusted through the PLC control system, combined with servo drive technology, which can adapt to the processing requirements of exhaust pipes of different diameters, and the processing process is highly stable46. 2. Structural design features ‌Optimized roller group configuration‌ The upper roller is a rigid steel roller, and the lower roller uses a steel roller core with an elastic layer (such as polyurethane) wrapped around it, which not only ensures the pressurization strength, but also avoids surface damage caused by metal contact, and improves the forming quality of the exhaust pipe46. ‌Automation Integration‌ Equipped with automatic loading, rolling and unloading functions, the whole process is automated through PLC control, reducing manual intervention and improving batch production efficiency45. III. Scope of application and limitations ‌Applicable scenarios‌ Mainly for metal sheets with a thickness of 0.5-6mm, especially good at processing carbon steel, stainless steel and aluminum plates with a yield strength of ≤350MPa, widely used in rapid prototyping of thin-walled cylindrical parts such as automobile exhaust pipes and ventilation ducts24. ‌Limitations‌ A single processing requires matching a specific upper roller mold, and the cost is relatively high when producing small batches and multiple specifications2; The maximum processing thickness is usually ≤10mm, which is not suitable for heavy plate processing28.

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.
