Key Components and Functionality

The production line consists of several critical components, each designed to optimize performance and reliability:

1. Auxiliary Machine Composition

• Single-Station Manual Uncoiler: Adapts to steel strip coils with an inner diameter of φ762mm and outer diameter of φ1800mm. It ensures smooth material handling with a belt width of 280mm and a weight capacity of 5 tons.
• Shearing and Welding Unit: Features hydraulic cutting and pneumatic pressing platforms. Manual welding is included, excluding automated welding machines.
• Four-Roller Delivery Machine: Maintains a steady supply of raw materials and ensures continuous production. It includes a gantry frame, upper and lower roller transmission, and a gear split axle box with vertical and horizontal pressing rollers.

2. Main Machine Composition

• Forming and Sizing Unit: Utilizes a seven-roller leveling system, seven flat and eight vertical forming rollers, and six flat and six vertical sizing rollers. This configuration ensures precise shaping and alignment of the steel pipe.
• Extrusion and Cooling System: Equipped with an extrusion roller shaft (φ70mm, 40Cr material) and a cooling water tank to maintain dimensional accuracy and structural integrity.
• Computer Flying Saw Machine: Capable of cutting pipes to fixed lengths (4–8m) with an accuracy of ±3mm. It includes a 55KW AC sawing motor and a 22KW DC driving motor, ensuring high-speed operations up to 80m/min.

3. Straightening Machine

• Four-Column Frame Structure: Eliminates stress and bending after welding. It features four upper rollers and two lower rollers (active lower roller) with a worm gear mechanism for manual pressure adjustment.
• Technical Parameters: A 30KW motor drives the straightening rollers (φ220×400mm upper, φ200×240mm lower) made of GCr15 material (HRC60–65). The system operates at 100m/min, accommodating pipes with diameters of φ60–φ89mm and wall thicknesses of 2.0–5.0mm.
