Auxiliary Machine Composition

The production line includes several auxiliary machines that contribute to its efficiency and precision:

• Single-station Manual Uncoiler: This uncoiler is designed to handle steel strip coils with an inner diameter of Ф762 mm and an outer diameter of Ф1800 mm. It features a belt width of 280 mm and a weight of 5 tons.
• Shearing and Welding Unit: Equipped with hydraulic cutting and pneumatic pressing platforms, this unit allows for manual welding (excluding the welding machine) to ensure the integrity of the steel pipes.
• Four-Roller Delivery Machine: This machine maintains a storage bin with sufficient raw materials and sends the welded steel strip into the storage bin. It includes 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 core of the production line, featuring advanced components for forming, sizing, and finishing the steel pipes:

• Technical Parameters: The machine utilizes Q195-Q345 strip steel with a thickness of 2.0-5.0 mm. It operates at a welding pipe speed of 60-80 m/min and is powered by a Z4-280-42 DC motor with 250 kW and a ZLY280-10 reducer.
• Unit Arrangement: The system includes a passive seven-roller leveling unit, feeding vertical roller, forming 7 flat and 8 vertical, sizing 6 flat and 6 vertical, guiding, extrusion, scraping, cooling water tank, and a Turkish ear head (8 rollers, single-sided 4 rollers).
• Shaft and Gear Box: The horizontal shaft has a diameter of Ф100 mm, while the vertical roller shaft is Ф60 mm. The gear box uses ZG35# spiral bevel gear transmission with a module of m=12 and material 20CrMnTi.

Computer Flying Saw Machine

The Computer Flying Saw Machine is a critical component for cutting the steel pipes to the desired length. Key features include:

• Sawing Pipe Diameter: Ф76-89 mm
• Steel Pipe Wall Thickness: 2-5 mm
• Fixed Length: 4-8 m
• Sawing Accuracy: ±3 mm
• Saw Blade Size: Ф900 mm
• Drive Motor: 55KW (AC) and 22KW (DC)

Straightening Machine

The straightening machine is designed to eliminate stress and bending in the steel pipes after forming and welding. It features a four-column frame structure with four upper rollers and two lower rollers. The lower roller is active, while the upper rollers are passive and pressed down by a worm gear (manual). Key technical parameters include:

• Motor Power: 30 kW
• Straightening Roller Dimensions: φ220×400 mm (upper) and φ200×240 mm (lower)
• Straightening Speed: 100 m/min
• Straightening Roller Diameter: φ120 mm
