W11S Series 3-Roll Hydraulic Plate Bending Machine (Universal)
Product Overview
The SLM W11S Series is an advanced 3-roll hydraulic plate bending machine engineered for high-precision and heavy-duty metal forming. Known as the "Universal" type, this machine features an upper roller with both vertical and horizontal movement capabilities. This allows for exceptional pre-bending of plate ends and the versatility to roll complex shapes such as cylinders, U-shapes, and multi-segment arcs. It is the premier solution for manufacturing high-pressure vessels, large-scale storage tanks, and wind tower components.
Key Features
- Universal Upper Roller Movement: The top roller of our 3-roll hydraulic plate bending machine moves vertically for bending and horizontally for precise pre-bending, significantly minimizing flat ends.
- High-Precision NC Control: Equipped with an advanced digital display and NC system, ensuring synchronized movement and high repeatability for batch production.
- Premium Hydraulic Components: Features world-class hydraulic valves (Bosch Rexroth or Huade) and high-pressure seals to ensure leak-free, stable operation under maximum load.
- 42CrMo Forged Rollers: All rollers are crafted from high-strength alloy steel, undergoing dual-stage heat treatment to achieve superior surface hardness and core durability.
- Integrated Safety Systems: Includes hydraulic overload protection and emergency stop controls to ensure maximum operator safety during the rolling process.
Working Principle
This 3-roll hydraulic plate bending machine operates by utilizing the horizontal movement of the top roller to position the plate for pre-bending. Once the ends are pre-bent, the top roller moves vertically to apply the required pressure, while the two bottom rollers act as the main drivers. This "Universal" movement eliminates the need to flip the plate, drastically reducing labor intensity and improving production efficiency.
