Pipe Production Line for Rolling Machine

Altron develops and customizes galvanized and stainless steel pipe production line rolling mills based on small and medium diameter oil fume ducts. This can improve the quality of each duct, ensure continuous and efficient production, and significantly reduce labor costs and process turnover.

I.Equipment Overview

The servo four-roll rounding automatic production line consists of a decoiler, leveling machine, hydraulic shear, conveying platform, servo four-roll rounding machine, inclined discharge platform, and other structures. It is used to replace manual work in automated rolling of cylinders, with almost no manual intervention required during the rolling process (except when the lifting beam cannot be used). The equipment is easy to operate and use, with high production efficiency.

Equipment Structure Composition

1) Decoiler:

This single-core decoiler has a maximum load capacity of 7 tons. It allows manual adjustment of expansion and contraction, with a coil inner diameter range of 480~600, facilitating the installation of coils with different specifications of cores. It is equipped with a pneumatic tensioning function for easy replacement and installation of materials, and has both manual and automatic unwinding capabilities.

2)Leveling Machine and Hydraulic Shear:

The leveling section adopts an upper 6-roller and lower 5-roller structure, totaling 11 shafts, made of 42CrMo. The surface of the leveling shafts undergoes medium-frequency treatment, with a heat treatment hardness of HRC54~56. After precision machining, the surface is hard chrome-plated to ensure a surface finish of 0.8. Reducer model: XJ-35 with a ratio of i=35; motor power: 5kw (servo motor); production speed: 10 meters per minute; feeding accuracy: length error ±0.5mm, diagonal error ±1mm.

 3)Conveying Platform:

This conveying platform adopts two structures: rollers and conveyor belts. Power is transmitted through an RV reducer, sprockets, and chains to realize the conveying function of sheet metal. The motor power is 1.1KW with a speed ratio of 25:1. It is also equipped with a positioning function, where the positioning motor is a servo motor with a speed ratio of 10:1. The conveyor belt is retractable for easy replacement of hydraulic shear tools. The roller surfaces are rubber-coated to prevent scratches on the surface of the metal sheets.

4)Servo Four Rolls Rolling Machine:

This part is responsible for rounding forming, consisting of an upper shaft, lower shaft, and side shafts. The shafts are made of 42CrMo, with surface medium-frequency treatment and a heat treatment hardness of HRC54~56. After precision machining, the surface is hard chrome-plated to ensure a surface finish of 0.8. The machine is driven by a servo motor. Clamping and lifting of the side rollers are realized by servo motors. It is also equipped with a lifting beam function to facilitate rolling of cylinders with different specifications and sizes, preventing overlap at the rolling mouth. It has an automatic discharge function: after rolling, the cylinder is pushed out to the liftable receiving platform via the automatic discharge mechanism.

5）Inclined Discharge Platform:

The main function is to collect the rolled air ducts to facilitate the next manual seam welding process!
