Fully Automatic Leaf Spring Ear Wrapping Production Line

Multi-Process Integration: Specifically designed for the end processing of automotive leaf springs, this line can efficiently complete plain wrapping (1/4, 3/4), center wrapping, as well as plain and center curling. 
The equipment features high rigidity and capacity, making it suitable for bracket ear production.
Superior Forming Precision: Utilizing crank-swing clamping heads and precision stroke pressing technology, the pressure plate adaptively adjusts to the leaf spring cross-section. 
This ensures excellent ear shape, roundness, and gap quality, with inner diameter tolerances kept within 0.3mm.
High Automation and Intelligent Control: The system is powered by a Siemens PLC and an HMI touchscreen, supporting automatic positioning calculations and parameter setups. 
The control cabinet includes meters with communication ports for seamless data collection, fault alarms, and maintenance management.
Integrated Precision Induction Heating: It integrates an efficient end induction heating system to maintain a stable steel heating temperature of 950±30°C or 975±25°C, ensuring optimal material plasticity for high-precision wrapping.
Efficient Continuous Operation: With a neat structural layout and a small footprint, the line is designed for continuous operation, capable of handling three-shift high-intensity production with an efficiency of 3-5 heads per minute.
