Comprehensive Machine Composition

Auxiliary Machine Components

The production line includes several auxiliary machines to ensure seamless operation:

• Single-Station Manual Uncoiler: Designed for manual expansion and contraction, it accommodates steel strip coils with an inner diameter of Ф762mm and an outer diameter of Ф1800mm. The belt width is 280 mm, and the weight capacity is 5 tons.
• Shearing and Welding Unit: Features hydraulic cutting, pneumatic pressing platforms, and manual welding (excluding welding machines) for precise edge preparation and joining.
• Four-Roller Delivery Machine: Ensures continuous material supply to the forming and sizing machine. It includes a gantry frame, upper and lower roller transmission, and gear split axle box guide vertical rollers.

Main Machine Components

The core of the system is the main machine, which includes:

• Seven-Roller Leveling Unit: Passively levels the steel strip before feeding it into the forming process.
• Forming and Sizing Section: Comprises 7 flat rollers and 8 vertical rollers for forming, followed by 6 flat and 6 vertical rollers for sizing.
• Extrusion and Cooling System: Ensures uniform pressure and temperature control during welding, with a cooling water tank for post-welding stabilization.
• Computer Flying Saw Machine: Cuts pipes to precise lengths (4–8 meters) with an accuracy of ±3 mm. It features a Ф900mm saw blade and a maximum cutting speed of 15 times/min.

Advanced Straightening Machine

The straightening machine eliminates residual stress and bending in the welded pipes. It employs a four-column frame structure with four upper rollers and two lower rollers. The lower roller is active, while the upper rollers are manually pressed via a worm gear mechanism. Key parameters include:

• Motor Power: 30 kW
• Roller Dimensions: φ220×400mm (upper), φ200×240mm (lower)
• Material: GCr15 (HRC 60–65)
• Operating Speed: 100 m/min

Applications and Industry Relevance

This production line is widely used in industries requiring high-quality welded steel pipes, such as:

• Oil and Gas: For transporting fluids and gases under high pressure.
• Construction: In structural frameworks and scaffolding systems.
• Automotive: For exhaust systems and chassis components.
• Manufacturing: As raw material for machinery and equipment.

The system’s ability to produce pipes with high dimensional accuracy and consistent quality makes it a preferred choice for global manufacturers.
