Key Components and Features

Auxiliary Machine Composition

• Single-Station Manual Uncoiler: Adapts to steel strip coils with an inner diameter of Ф762mm and outer diameter of Ф1800mm. It ensures stable material supply with a belt width of 280mm and a weight capacity of 5 tons.
• Shearing and Welding Unit: Features hydraulic cutting and pneumatic pressing platforms. Manual welding (excluding welding machines) ensures flexibility in production.
• Four-Roller Delivery Machine: Maintains a steady supply of raw materials and feeds the welded steel strip into the storage bin. Equipped with a gantry frame, upper/lower roller transmission, and gear split axle box for precise control.

Main Machine Composition

• Technical Parameters: Utilizes Q195-Q345 strip steel with thicknesses of 2.0-5.0mm. The welding pipe speed ranges from 60-80m/min, supported by a DC motor (Z4-280-42, 250KW) and a reducer (ZLY280-10).
• Unit Arrangement: Includes passive seven-roller leveling, forming (7 flat + 8 vertical), sizing (6 flat + 6 vertical), and extrusion systems. The Turkish ear head (8 rollers, single-sided 4 rollers) ensures uniform pipe shaping.
• Material Specifications: Horizontal shafts (Ф100mm) and vertical rollers (Ф60mm) are made of 40Cr, quenched and tempered. Extrusion rollers (Ф70mm) also use 40Cr material for durability.
• Computerized Flying Saw: Capable of cutting pipes with a diameter of φ76-89mm and wall thickness of 2-5mm. It operates at a maximum speed of 80m/min with a 55KW saw motor and 22KW driving motor.
