Multi-functional Integrated Processing: Specifically designed for automotive leaf spring end processing, this line efficiently handles plain curling, plain wrapping, center curling, and center wrapping, offering exceptional production flexibility.
Superior Machining Precision: Featuring a high-rigidity mainframe, crank-swing clamping heads, and precise stroke pressing technology, the line ensures excellent ear shape, roundness, and gap quality. The inner diameter tolerance is kept within 0.3mm, and the center distance tolerance reaches ±1.5mm.
High Automation and Intelligent Control: Controlled by a Siemens PLC system and an HMI touchscreen, the line allows operators to simply input product parameters for automatic setup. It achieves a production efficiency of 3-5 heads per minute and supports continuous three-shift operations.
Integrated Precision Induction Heating: The line integrates advanced induction heating systems, maintaining precise leaf spring heating temperatures at 975±25℃ (or 950±30℃ depending on requirements), providing optimal conditions for forming.
Lean Data Management: The control cabinet is equipped with digital meters featuring communication ports, supporting the collection and management of production data, fault alarms, and maintenance schedules for digital factory integration.
