Product Description

Product Description

Multi-Function Cold Rolling Elongation Straightening & Cutting Line

Production Line Features

1. Fully Integrated Inline Processing
Finished cold-rolled rebar is fed directly into the CNC high-speed straightening and cutting system without the need for recoiling or packaging, significantly improving efficiency.

2. High Cutting Accuracy
Cutting length error is controlled within ±5 mm, ensuring high dimensional accuracy and consistent product quality.

3.Continuous Operation, High Efficiency
Equipped with dual decoilers and CNC buffer unloading frame, enabling continuous feeding and uninterrupted offloading, reducing downtime, labor, energy consumption, and space requirements.

4. Multi-Functional & Versatile
Capable of processing various raw materials and meeting different process requirements:

    Cold-rolled three-ribbed rebar with high strength – online straightening and cutting without damage.
    Grade III coiled deformed rebar – elongation  straightening and cutting, without damaging ribs; elongation is adjustable and easy to operate.
    Coiled round wire (plain rebar) – elongation straightening and cutting, with controllable elongation and flexible operation.

Raw Material

Finished Product

Compatible with your local hot-rolled rebar grades (Ribbed or Plain)

Diameters ranging from 6mm-14 mm.

(Provide the rebar grades used in your country)

Customized(Straight lengths, with optional recoiling)

Elongation Rate 8-14% 

Diameters ranging from 5mm-12mm

Main Applications:

1. Rebar Recycling: reuse of scrap or leftover steel bars
2. Custom Fabrication: workshops with variable order requirements
3. Resource-Efficient Projects: green construction and material-saving sites
4. Repair and Retrofitting: strengthening existing structures
5. Mixed-Grade Processing: handling different rebar qualities in one line
Key Advantages:

1. Dual Functionality: can stretch only or stretch + cold roll for strength boost
2. Material Savings: extends rebar length by 10–25%, reducing waste
3. Flexible Upgrade: optional rolling module for on-demand strength enhancement
4. Mid-Range Diameter: optimized for 6–12 mm bars
5. Continuous Production: supports high-efficiency workflow with CNC buffer

The complete production line consists of the following units:
 
Dual decoilers, anti-twist cage, descaling unit, 6-cylinder hydraulic elongator, cold rolling mill (1–2 optional), steering mechanism, main traction unit (1–2 optional), CNC high-speed straightening & cutting machine, automatic alignment conveyor, centralized control panel, recoiler unit(optional).

1. Dual Decoilers
Enable continuous feeding from two coils, reducing downtime and manual work. Suitable for both wire rod and rebar.

2. Anti-Twist Cage
Prevents wire twisting and ensures smooth, stable feeding into downstream processes.

3. Descaling Unit
Removes surface oxide scale via mechanical or water-jet methods, improving cold rolling quality.

4. Six-Cylinder Hydraulic Elongator
Provides uniform, adjustable elongation for improved ductility and straightness.

5. Cold Rolling Mill (1–2 units optional)
Forms ribbed or smooth surface on rebar; optional dual mills for enhanced flexibility and precision.

6. Steering Mechanism
Automatically adjusts rebar direction for multi-path processing and quick product changeover.

7. Main Traction Unit (1–2 units optional)
Delivers stable traction force with servo control for synchronized, uniform movement.

8. CNC High-Speed Straightening & Cutting Machine
Performs inline straightening and cutting with ±5 mm accuracy and high automation.

9. Automatic Alignment Conveyor
Collects and aligns finished rebar for easy handling and continuous discharge.

10. Centralized Control Panel
PLC + touchscreen system for full-line control, real-time monitoring, and multi-language support.

11.Recoiler unit (optional): 
Rewinds straightened/cut bars into compact coils for flexible storage or transport.
