Product Details
Precision Roll Forming Machine for 20x20mm Welded Square Tube
Production with Laser Welding and Flying Saw Cutting
These introductions refer only to the production line and
configuration shown in the main image. Each machine is
custom-built. Metalign welcomes your inquiry and provides the right
production line—forming metal into profiles aligned to your needs.
1. Production Line Overview
- This cold roll forming line is designed for clients in the
construction, industrial machinery, and storage systems sectors.
The line excels in producing high-precision welded square tubes
with laser welding, offering robust durability and quality. Its
automated features make it ideal for large-scale, efficient
production.
2. Profile Description
- This welded square tube is made from 1.2mm thick steel, featuring a
precise 20x20mm cross-section. It offers high strength and
dimensional accuracy, ideal for structural applications. Its
primary uses include scaffolding, shelving, and industrial
framework, benefiting from advanced laser welding technology.
3. Production Process
- 3T Decoiler → Guiding (Strip Type) → Roll Former (14 Stations) →
Laser Welding → Correction → Tracking Saw Cutting
- The process starts with the 3T Decoiler feeding the steel strip,
which is guided through the Roll Former for precise 14-stage
shaping. The laser welding ensures strong seam integrity.
Afterward, the tube is corrected for straightness, and the tracking
saw cutting delivers accurate lengths.
4. Technical Parameters
| Machine | Analysis |
| 3T Decoiler | Handles up to 3 tons of steel coils, ensuring steady material feed. |
| Guiding (Strip Type) | Precise material alignment, preventing deformation during shaping. |
| Roll Former (14 Stations) | 14-stage forming provides optimal shaping accuracy and dimensional
stability. |
| Laser Welding | Provides high precision welds, minimizing heat distortion and
ensuring strength. |
| Correction | Corrects post-welding distortions, ensuring straightness and
quality. |
| Tracking Saw Cutting | Ensures precise cutting lengths, improving accuracy for final
products. |
5. Key Focus
- Precision Welding: Laser welding ensures strong and precise seams with minimal
distortion.
High-Quality Tube Formation: The 14-station roll forming process offers perfect shape and size
accuracy.
Post-Production Quality Control: Correction and tracking saw cutting enhance product consistency
and precision.
Automated Production: Efficient and consistent operation for large-scale production
needs.
