Steel Coil
straightening machine for Press Machines – Advanced Tension Leveling Solution for Precision Metal Processing This state-of-the-art steel coil straightening machine is engineered specifically for press machines in industrial metalworking environments. Designed to deliver consistent flatness and eliminate residual curvature in coiled strip materials, it combines the precision of a roller straightener with the controlled elongation capabilities of a
stretcher leveler. Ideal for high-volume production lines, this tension leveling unit ensures superior surface quality and dimensional accuracy—key factors in modern manufacturing processes such as stamping, bending, and forming. Key Features: - Fully digital transmission control system integrated with PLC technology for precise speed regulation and process stability - Constant elongation and rolling pressure management for uniform material deformation without over-stretching - Automated threading, unloading, acceleration, deceleration, and shutdown functions reduce manual intervention and increase throughput - Dual-action mechanism: tension rollers apply controlled stretching while bending rollers induce repeated plastic deformation to remove internal stresses - Robust construction using high-grade alloy components ensures long-term durability under continuous operation Detailed Description: The core innovation lies in its hybrid approach—merging tensile force from the roller system with multi-directional bending cycles that progressively correct warping and curling. Unlike traditional straighteners that rely solely on mechanical pressure, this machine applies dynamic tension during the straightening process, enabling more effective stress relief across various steel grades including mild steel, stainless steel, and galvanized sheets. Its intelligent control panel allows operators to set specific parameters based on material thickness, width, and yield strength, making it adaptable to diverse applications in automotive, appliance, and construction industries. The inclusion of real-time feedback loops enhances repeatability and minimizes scrap rates, contributing directly to cost savings and improved product consistency. Use Cases: This equipment excels in strip processing lines where precision flatness is critical before feeding into CNC punching presses, roll forming machines, or laser cutting systems. It’s widely adopted in sheet metal fabrication facilities handling coils up to 1.5 mm thick, particularly those involved in producing components for electrical enclosures, HVAC ducts, and structural panels. Whether you're working with cold-rolled or hot-rolled steel, the machine maintains tight tolerances within ±0.1 mm per meter, ensuring compatibility with downstream automated assembly lines. User Feedback: Operators frequently highlight how the seamless automation reduces operator fatigue and increases line uptime. One user noted, “Since installing this
tension leveler, our scrap rate dropped by nearly 40%, and we no longer need to manually adjust for coil springback.” Another praised the intuitive interface: “Even new staff can operate it after minimal training thanks to the clear visual indicators and step-by-step prompts.” Frequently Asked Questions: What makes this straightening machine different from conventional roller levellers? It introduces controlled tension during the straightening process, which significantly improves material flatness compared to purely mechanical bending methods. This results in better performance in subsequent forming operations. Can it handle different coil widths and thicknesses? Yes, the system supports adjustable roller spacing and tension settings, allowing efficient processing of materials ranging from 200 mm to 1200 mm wide and 0.3 mm to 1.5 mm thick. Is maintenance required? Routine checks are recommended every 500 hours, including lubrication of bearings and inspection of roller surfaces. The modular design simplifies component replacement and minimizes downtime. How does it improve productivity? By automating key steps like threading and unloading, and integrating smooth acceleration/deceleration profiles, it reduces cycle times and eliminates bottlenecks common in manual setups.
