Key Components and Features

**Auxiliary Machine Composition**: The production line includes several auxiliary machines that ensure seamless operation. The single-station manual 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 capacity of 5 tons. The shearing and welding unit employs hydraulic cutting and pneumatic pressing platforms, with manual welding capabilities (excluding the welding machine). The four-roller delivery machine ensures continuous production by storing raw materials and feeding the welded steel strip into the storage bin. Its structure includes a gantry frame, upper and lower roller transmission, and a gear split axle box with guide vertical rollers and horizontal pressing rollers.

**Main Machine Composition**: The main machine is the core of the production line, featuring a technical setup that includes a DC motor (Z4-280-42, 250KW) and a reducer (ZLY280-10). The unit arrangement includes a passive seven-roller leveling system, feeding vertical rollers, forming 7 flat and 8 vertical rollers, sizing 6 flat and 6 vertical rollers, and a Turkish ear head with 8 rollers (single-sided 4 rollers). The horizontal shaft has a diameter of Ф100 mm, while the vertical roller shaft is Ф60 mm, made of 40Cr material and treated for quenching and tempering. The extrusion roller shaft is Ф70 mm, also made of 40Cr, and the gear box uses ZG35# spiral bevel gears with a module of m=12 and material 20CrMnTi.

**Computer Flying Saw Machine**: This component is critical for cutting the steel pipes to the required lengths. It includes a bed, gears, rack box, saw car, fixture, speed measurement system, air system, drive system, electrical system, and rollers. The sawing pipe diameter ranges from Ф76 to 89 mm, with wall thicknesses of 2–5 mm. The fixed length is 4–8 m, with an accuracy of ±3 mm. The maximum sawing frequency is 15 times per minute, and the maximum running speed is 80 m/min. The saw blade size is Ф900 mm, with a trolley travel of 2 m. The sawing motor (AC) is 55KW, and the driving motor (DC) is 22KW, with an air pressure of 5–7Kg/cm².

**Straightening Machine**: The straightening machine is designed to eliminate stress and bending after steel pipe 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 roller is passive and pressed down by a worm gear (manual). The motor is 30KW, and the straightening rollers have diameters of φ220×400 mm (upper) and φ200×240 mm (lower), made of GCr15 material with a hardness of HRC60-65. The straightening speed is 100 m/min, and the angle between the straightening roller and the steel pipe is 30°.
