Overview

The 60 mm Square Tube Production Line with Roller Quick-Change is designed for efficient and flexible manufacturing of square welded tubes for industrial applications. The line is suitable for producing square tubes up to 60 mm, as well as round and rectangular tubes within the same size range.

By integrating a roller quick-change system, this production line significantly reduces size change time and improves production flexibility, making it ideal for factories handling multiple specifications and small to medium batch orders.

The line uses high-frequency ERW welding technology and is suitable for processing carbon steel and galvanized steel, ensuring stable welding quality and reliable long-term operation.

Production Process Description

The square tube production line starts from the decoiler, where the steel strip is uncoiled and guided into the line. The strip then passes through leveling and enters the forming section.

In the forming section, precision rolls gradually shape the steel strip into a round tube. Roll forming is stable and controlled, which helps maintain consistent geometry before welding. The high-frequency solid-state welder heats the strip edges, and squeeze rolls press them together to form a strong and clean longitudinal weld.

After welding, the tube is cooled and transferred to the sizing section, where it is accurately formed into square tubes up to 60 mm or other required profiles. At the end of the line, a flying saw automatically cuts the tube to the preset length without stopping production.

Roller Quick-Change System Advantage

A key feature of this production line is the roller quick-change system, which replaces traditional manual roll change methods.

With this system, roll units are pre-assembled and positioned using guided structures. During size change, rolls can be replaced or adjusted quickly without complex disassembly.

Main benefits include:

• Size change completed in approximately 30 minutes

• Reduced production downtime

• Less dependence on operator experience

• Repeatable roll positioning for stable forming quality

The roller quick-change system allows one production line to handle multiple square tube sizes efficiently, which is especially important for flexible manufacturing environments.

Automation and Control

The 60 mm square tube production line is equipped with PLC control and a touch screen interface. All key parameters, including line speed, welding status, and cutting length, can be monitored and adjusted easily.

The system is simple to operate and quick to learn, making it suitable for both small workshops and large tube plants. The line runs smoothly with low vibration and low maintenance requirements.

Technical Reliability and Machine Structure

The machine is built with:

• Rigid frames

• High-strength bearings

• Precision-machined shafts

• Durable forming rolls with long service life

These features ensure stable operation, reduced downtime, and consistent tube quality over long production cycles. The design also allows future upgrades such as automatic loading systems, additional cooling units, and packing equipment.

Application Areas

The 60 mm square tube production line is widely used in:

• Furniture and shelving systems

• Construction and building materials

• Automotive components

• Light mechanical and structural products

Its flexible design supports round, square, and rectangular tube production on one line, meeting diverse market demands.
