Fully Automatic Leaf Spring Variable Cross-Section Rolling Production Line

High-Efficiency Automated Production: Specifically designed for variable cross-section rolling of automotive leaf spring ends, this line supports high-speed operations of 180-480 heads per hour, meeting the demands of large-scale continuous production.
Superior Structural Rigidity and Lifespan: The mainframe features a robust "Paifang" (large-scale gate) structure to ensure maximum rigidity. With a roller diameter of 220mm, the equipment's service life is approximately 10% longer than similar domestic products.
High-Precision Processing Control: The system offers exceptional precision, maintaining a rolling thickness tolerance of ±0.15mm and a width tolerance within ±0.5mm, ensuring consistent product geometry.
Intelligent Control System: Controlled by a PLC and an HMI touchscreen, the system provides real-time display of product graphics, parameters, and rolling curves. It can store over 500 product recipes, allowing for instant recall and backup.
Flexible Product Changeover: Utilizing cold-end positioning, the equipment allows for quick variety switches by simply adjusting the rear positioning. Additionally, a full range of auxiliary units enables flexible configurations for diverse automated lines.
Digital Management Support: The control cabinet is equipped with digital meters featuring communication ports for easy data collection. The system integrates functional modules for production monitoring, fault alarms, and maintenance management.
