Core Components and Functionality

The production line consists of multiple specialized units designed to ensure efficiency, precision, and quality. Each component plays a critical role in the manufacturing process:

Auxiliary Machine Composition

• Single-station manual uncoiler: Adapts to steel strip coils with an inner diameter of Ф762mm and outer diameter of Ф1800 mm. It ensures smooth feeding of raw materials into the system.
• Shearing and welding: Equipped with hydraulic cutting and pneumatic pressing platforms for precise material handling. Manual welding (excluding welding machines) ensures adaptability to various production needs.
• Four-roller delivery machine: Maintains a steady supply of raw materials to the forming and sizing machine. It features a gantry frame, upper and lower roller transmission, and gear split axle box for stability and control.
