A 120x3500 Horizontal Down-adjusting Plate Rolling Machine is a heavy-duty industrial forming machine designed for bending and rolling metal plates into cylindrical, conical, or curved shapes with high precision. It is widely used in metal fabrication, shipbuilding, pressure vessel production, bridge construction, and large-scale steel structure manufacturing. With a rolling capacity of 120 mm in thickness and 3500 mm in working width, this machine is suitable for processing large and thick steel plates that require strong pressure, stable performance, and accurate control.The horizontal down-adjusting structure is one of the key features of this machine. In this design, the lower roller moves vertically to adjust the rolling radius and plate clamping force. This configuration provides excellent stability during operation and ensures better control over the forming process. Compared with traditional machines, the down-adjusting system improves rolling accuracy, reduces slippage, and helps achieve more consistent workpiece shapes. It is especially effective for thick plates and high-strength materials that demand strong and even deformation.This plate rolling machine is typically equipped with three rollers: one upper roller and two lower rollers. The upper roller applies the main bending force, while the lower rollers support the plate and guide the rolling process. The machine’s robust frame is manufactured from high-strength welded steel, giving it excellent rigidity and durability under heavy loads. The rollers are made from high-quality alloy steel and undergo heat treatment to improve wear resistance and service life. This ensures that the machine can operate reliably for long periods in demanding industrial environments.The 120x3500 Horizontal Down-adjusting Plate Rolling Machine is usually driven by a powerful hydraulic or mechanical system, depending on the configuration. The drive system delivers smooth and powerful rotation, allowing the machine to roll plates efficiently with minimal vibration. Advanced control systems may be included to improve operational convenience, making it easier for operators to set parameters, monitor movement, and achieve precise results. Safety features are also important, including overload protection, emergency stop functions, and stable clamping control to ensure secure and reliable operation.This machine is ideal for forming a wide range of materials, including carbon steel, stainless steel, alloy steel, and other metal plates. It can produce different diameters and curves according to production requirements, making it highly versatile for custom fabrication work. Its large working width of 3500 mm allows it to handle oversized sheets and reduce the need for multiple passes, improving productivity and efficiency.In summary, the 120x3500 Horizontal Down-adjusting Plate Rolling Machine is a powerful and reliable solution for large-scale metal plate forming. It combines strong rolling capacity, precise down-adjusting control, durable construction, and efficient performance. For industries that require accurate rolling of thick and wide metal plates, this machine offers excellent productivity, stability, and long-term value.
