Key Components of the Production Line

Auxiliary Machine Composition

The auxiliary machines ensure seamless operation and material handling throughout the production process. Key components include:

• Single-station manual uncoiler: Designed for manual expansion and contraction, it accommodates steel strip coils with an inner diameter of Φ762 mm and an outer diameter of Φ1800 mm. The belt width is 280 mm, and it can handle up to 5 tons of material.
• Shearing and welding: Equipped with hydraulic cutting and pneumatic pressing platforms, this system supports manual welding (excluding welding machines) for precision and flexibility.
• Four-roller delivery machine: This machine maintains a steady supply of raw materials to the forming and sizing unit. It features a gantry frame, upper and lower roller transmission, and a gear split axle box with guide vertical and horizontal pressing rollers.

Main Machine Composition

The main machine is the heart of the production line, responsible for forming, welding, and finishing the steel pipes. Its components include:

• Unit arrangement: The system employs a passive seven-roller leveling unit, feeding vertical rollers, forming (7 flat and 8 vertical), sizing (6 flat and 6 vertical), guiding, extrusion, scraping, and a cooling water tank. A Turkish ear head (8 rollers, single-sided 4 rollers) ensures precision.
• Roller specifications: Horizontal shafts (Φ100 mm) and vertical roller shafts (Φ60 mm) are made of 40Cr material, quenched and tempered. The extrusion roller shaft (Φ70 mm) also uses 40Cr material.
• Computer flying saw machine: This advanced unit includes a bed, gears, rack box, saw car, and speed measurement system. It can cut pipes with diameters of Φ76–Φ89 mm and wall thicknesses of 2.0–5.0 mm, achieving a maximum sawing speed of 80 m/min.
• Straightening machine: Featuring a four-column frame structure, it eliminates stress and bending after welding. The machine uses GCr15 material for rollers, with a straightening speed of 100 m/min.
