Machine Composition and Components

The production line is composed of multiple auxiliary and main machines, each designed to ensure seamless operation and high-quality output. Here’s a breakdown of the key components:

Auxiliary Machines

• Single-Station Manual Uncoiler: This unit features a manual expansion and contraction mechanism, accommodating steel strip coils with an inner diameter of φ762 mm and an outer diameter of φ1800 mm. It ensures stable material feeding with a belt width of 280 mm and a weight capacity of 5 tons.
• Shearing and Welding Unit: Equipped with hydraulic cutting and pneumatic pressing platforms, this component allows manual welding (excluding the welding machine) for precise seam formation.
• Four-Roller Delivery Machine: Designed to maintain a steady supply of raw materials, this machine includes a gantry frame, upper and lower roller transmission, and a gear split axle box. Its technical parameters include a feeding roller diameter of φ170 mm, a drive motor of YCT250-4A (18.5KW), and a feeding speed of 140 m/min.
• Cage Looper: This storage system ensures continuous production by holding raw materials for the forming and sizing machine. It features an adjustable frame structure to accommodate varying steel strip widths.

Main Machine Components

• Technical Parameters: The main machine processes Q195–Q345 strip steel with a thickness of 2.0–5.0 mm. It produces pipes with a diameter of φ76–φ89 mm at a speed of 60–80 m/min. Key motors include a DC motor (Z4-280-42, 250KW) and a reducer (ZLY280-10).
• Unit Arrangement: The system includes passive seven-roller leveling, 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 precise shaping.
• Roller Shafts: Horizontal shafts (φ100 mm) and vertical roller shafts (φ60 mm) are made of 40Cr material and undergo quenching and tempering. Extrusion roller shafts (φ70 mm) also use 40Cr material.
• Gearbox: The gearbox employs ZG35# material with spiral bevel gears (module m=12) and 20CrMnTi alloy for durability.
• Computer Flying Saw Machine: This unit includes a bed, gears, rack box, saw car, and a speed measurement system. It can cut pipes with a diameter of φ76–89 mm, wall thickness of 2–5 mm, and a fixed length of 4–8 meters. The saw blade size is φ900 mm, with a maximum running speed of 80 m/min.
