cage loop

Video Specification The cage accumulator is a commonly used material storage device in ERW tube mill production lines. It serves as a buffer between the uncoiler, shear and butt welder, and the forming mill, ensuring continuous production without interruption and improving the overall line efficiency. The steel strip is stored helically around a vertical cage frame, maintaining stable strip tension and allowing quick feeding. It is suitable for the production of carbon steel, stainless steel, and alloy steel pipes, especially for medium to high-capacity requirements. 1. Application Solutions Standard Solution : Uncoiler → Shear & Butt Welder → Cage Accumulator → Forming Mill → Welding/Sizing → Flying Saw → Stacking. High-Speed Upgrade : Integrates with automatic uncoiler, double-head shear and butt welder, and PLC-based speed control for fully automated production lines. Heavy-Duty Solution : Reinforced cage frame with servo-controlled tension system, suitable for producing high-strength steel strips of thickness 3.0–4.5mm and above. 2. Technical Requirements The cage frame must adopt high-strength welded structure, with shot blasting and anti-corrosion treatment. Key rotating parts shall be equipped with imported bearings to ensure stable and vibration-free operation. Tension control system must respond quickly to avoid strip slack or breakage. Anti-strip-jumping devices must be installed for high-speed running safety. Emergency stop system and protective fencing must meet CE or local safety standards. Maintenance access doors must be provided for easy servicing. 3. Technical Specifications (Customizable) Item Parameter Applicable Strip Width 60mm–600mm (customizable) Applicable Strip Thickness 0.5mm–4.5mm Storage Capacity 100m–250m (customizable) Floor Space Required Approx. L5m × W1m × H4m Max. Strip Speed 80–120m/min (depends on line design) Cage Frame Material High-strength alloy steel Tension Adjustment Electric/Pneumatic control Safety Features Limit switches, anti-strip-jumping fence, emergency braking 4. Key Advantages of Cage Accumulator Simple structure, cost-effective : About 20% lower cost compared to disk accumulators. Easy maintenance : Mostly mechanical parts, simple and low-cost servicing. Stable operation : Natural helical storage ensures uniform strip tension, reducing forming defects. Strong adaptability : Suitable for various materials and strip thicknesses. Moderate footprint : Saves about 30% of space compared to traditional horizontal accumulators. 5. Comparison Between Cage Accumulator and Disk Accumulator Item Cage Accumulator Disk Accumulator Investment Cost Lower Higher (requires heavy-duty drive systems) Applicable Speed Medium to high speed (up to 120m/min) Ultra-high speed (up to 200m/min or more) Footprint Moderate Larger Storage Capacity Large Very large Safety High (with safety devices) High Maintenance Complexity Low (mainly mechanical) High (servo systems require maintenance) Typical Applications Standard ERW tube mills Ultra-high speed, mass production lines Summary : If ultra-high speed (150m/min and above) is required, a disk accumulator is preferred. For standard medium-high speed tube mills, a cage accumulator is the optimal choice considering cost and reliability. 6. Cage Accumulator Selection Guide Production Line Parameters Recommended Configuration Notes Strip Width ≤ 200mm Small-size Cage Accumulator (Light Duty) Storage capacity 100–150 meters Strip Width 200–400mm Standard Cage Accumulator (Medium Duty) Storage capacity 150–200 meters Strip Width ≥ 400mm Large-size Cage Accumulator (Heavy Duty) Storage capacity 200+ meters, reinforced structure Strip Thickness ≤ 2.0mm Standard Tension Control Conventional motor or pneumatic control Strip Thickness 2.0–4.5mm Reinforced Tension Control Requires high-response tension system Line Speed ≤ 80m/min Standard Mechanical Safety Devices Regular emergency stop protection Line Speed 80–120m/min Enhanced Tension & Anti-Strip-Jumping System Recommended to add emergency braking and reinforced guardrails High Surface Protection Requirement Non-contact Strip Guiding System Prevents surface scratching, ideal for stainless steel strips Limited Space (Low Factory Height) Low-profile Cage Accumulator (Custom) Custom design to reduce footprint Continuous Production (High Automation) Integrate with Shear & Butt Welder + PLC control Recommended for automatic speed synchronization 【Notes on Selection】 Strip width and thickness are the basic criteria for selecting the cage accumulator model. Line speed determines whether enhanced tension control and safety features are needed. Factory layout restrictions and surface protection needs should be communicated early for tailored designs. For cost-performance balance , the standard medium-duty cage accumulator is recommended for most ERW production lines.
