The system's design allows for seamless integration into existing manufacturing workflows, reducing downtime and increasing productivity.

Core Components and Auxiliary Machines

The production line consists of multiple specialized units, each contributing to the efficiency and accuracy of the welding process. Key components include:

1. Single-Station Manual Uncoiler

This unit is designed to handle steel strip coils with an inner diameter of Ф762mm and an outer diameter of Ф1800 mm. Its manual operation allows for flexibility in adjusting to different material sizes, while the 280 mm belt width ensures stability during uncoiling.

2. Shearing and Welding Unit

The shearing and welding system combines hydraulic cutting with pneumatic pressing and manual welding. This setup ensures precise edge preparation and strong welds, critical for the structural integrity of the final product. The absence of an automated welding machine allows for customization based on specific project requirements.

3. Four-Roller Delivery Machine

This component maintains a continuous supply of raw materials to the forming machine. Its gantry frame structure and gear split axle box provide stability, while the feeding roller diameter of Ф170mm ensures smooth material flow at a speed of 140 m/min.

Main Machine Composition and Technical Details

The main machine is the heart of the production line, responsible for forming and sizing the steel pipes. Its technical specifications include:

• Raw Materials: Q195-Q345 steel strips with thicknesses of 2.0–5.0 mm.
• Welding Pipe Diameter: φ76–φ89 mm.
• Welding Pipe Speed: 60–80 m/min.
• Motor: Z4-280-42, 250KW (DC motor).
• Reducer: ZLY280-10, 1 set.

The machine's unit arrangement includes a passive seven-roller leveling system, a forming section with 7 flat and 8 vertical rollers, and a sizing section with 6 flat and 6 vertical rollers. The horizontal shaft has a diameter of Ф100mm, while the vertical roller shaft is Ф60mm. These components are crafted from high-strength materials like 40Cr, ensuring durability under continuous operation.

Computer Flying Saw Machine

The Computer Flying Saw Machine is a critical component for cutting the welded pipes to the desired length. Its specifications include:

• Sawing Pipe Diameter: φ76–89 mm.
• Steel Pipe Wall Thickness: 2–5 mm.
• Fixed Length: 4–8 m.
• Maximum Sawing Times: 15 times/min.
• Saw Blade Size: Ф900 mm.

This machine ensures precise cuts with an accuracy of ±3 mm, meeting industry standards for quality control. The integration of a speed measurement system and air pressure regulation enhances its reliability and efficiency.

Straightening Machine

The straightening machine eliminates stress and bending in the welded pipes, ensuring they meet dimensional requirements. Key features include:

• Motor Power: 30 kW.
• Straightening Rollers: φ220×400 mm (upper), φ200×240 mm (lower).
• Material: GCr15 for upper rollers, 40Cr for lower rollers.
• Straightening Speed: 100 m/min.

The machine's four-column frame structure and adjustable roller system allow for customization based on pipe diameter and wall thickness, ensuring optimal performance for various applications.

Applications and Industry Relevance

The Welded Pipe Production Line is widely used in industries requiring high-quality steel pipes, such as:

• Oil and Gas: For transporting fluids and gases through pipelines.
• Construction: In structural frameworks and scaffolding.
• Manufacturing: For producing components in machinery and equipment.
• Infrastructure: In water supply and drainage systems.

Its ability to produce pipes with precise dimensions and consistent quality makes it a preferred choice for companies seeking reliable and cost-effective solutions.
