Key Components and Functionality

Auxiliary Machine Composition

The production line includes several auxiliary machines that ensure smooth operation and material handling:

• Single-Station Manual Uncoiler: This device features a manual expansion and contraction mechanism, capable of accommodating steel strip coils with an inner diameter of Φ762 mm and an outer diameter of Φ1800 mm. The belt width is 280 mm, and the unit weighs 5 tons.
• Shearing and Welding Unit: Equipped with hydraulic cutting and pneumatic pressing platforms, this component allows for manual welding (excluding welding machines) to ensure precise seam formation.
• Four-Roller Delivery Machine: Designed to store raw materials and feed the welded steel strip into the storage bin, this machine includes a gantry frame, upper and lower roller transmission, and a gear split axle box with guide vertical rollers and horizontal pressing rollers.
• Cage Looper: This unit stores raw materials for the forming and sizing machine, ensuring continuous production. It features an integral frame structure with adjustable support and tension rollers.

Main Machine Composition

The core of the production line consists of advanced machinery for forming, welding, and finishing steel pipes:

• Technical Parameters: The system processes Q195-Q345 strip steel with thicknesses ranging from 2.0 to 5.0 mm. It produces pipes with diameters of Φ76–Φ89 mm at a speed of 60–80 m/min. Key components include a DC motor (Z4-280-42, 250KW) and a reducer (ZLY280-10).
• Unit Arrangement: The machine features a passive seven-roller leveling system, feeding vertical rollers, forming sections with 7 flat and 8 vertical rollers, and sizing sections with 6 flat and 6 vertical rollers. Additional components include a guiding system, extrusion unit, scraping device, and a cooling water tank.
• Extrusion and Roller Shafts: The extrusion roller shaft (Φ70 mm) and vertical roller shaft (Φ60 mm) are made of 40Cr material, hardened and tempered for durability.
• Computer Flying Saw Machine: This unit includes a bed, gears, rack box, saw car, and drive system. It can cut pipes with diameters of Φ76–Φ89 mm and wall thicknesses of 2–5 mm, with a maximum sawing speed of 15 times per minute and a travel distance of 2 meters.
• Straightening Machine: Designed to eliminate stress and bending after welding, this machine uses a four-column frame with upper and lower rollers. It operates at a speed of 100 m/min and handles pipes with diameters of Φ60–Φ89 mm.
