Key Components and Functionality

Auxiliary Machines

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

• Single-station Manual Uncoiler: Designed for manual expansion and contraction, this uncoiler adapts to steel strip coils with an inner diameter of 762mm and an outer diameter of 1800mm. It ensures consistent material feeding into the system.
• Shearing and Welding Unit: Equipped with hydraulic cutting and pneumatic pressing platforms, this unit allows manual welding (excluding automated welding machines) for precise seam formation.
• Four-Roller Delivery Machine: This machine maintains a steady supply of raw materials to the forming and sizing unit. It features a gantry frame, upper and lower roller transmission, and a gear split axle box for enhanced stability.

Main Machines

The core of the production line consists of the following components:

• Forming and Sizing Unit: This unit includes seven passive leveling rollers, seven flat rollers, eight vertical rollers, six flat sizing rollers, and six vertical sizing rollers. It ensures the steel strip is accurately formed into a pipe shape.
• Extrusion and Scraping Unit: The extrusion rollers, with a diameter of 70mm, apply pressure to the welded seam, while the scraping mechanism removes excess material for a smooth finish.
• Computer Flying Saw: This advanced sawing system can cut pipes with a diameter of 76–89mm and a wall thickness of 2–5mm. It features a 900mm saw blade and a maximum cutting speed of 80m/min.
• Straightening Machine: Designed to eliminate stress and bending after welding, this machine uses four upper rollers and two lower rollers (with the lower roller being active) to ensure straight, high-quality pipes.
