Core Advantages
Precision Engineering for Critical Applications
You get zero-taper thread profiles through our high-hardness alloy steel rolling dies (HRC 62-65). The automatic diameter compensation algorithm adjusts stripping and rolling depth in real time based on sensor feedback. This ensures your threaded joints exceed base metal yield strength requirements for seismic-resistant structures.
Intelligent Automation Reducing Operational Costs
Your production line operates with synchronized multi-head configuration under centralized numerical control. The PLC touch-screen interface provides multi-language operation and real-time fault diagnostics. You eliminate manual threading inconsistencies while cutting labor costs by over 70%.
High-Volume Output for Demanding Projects
The system handles 80-120 pieces per hour in cutting mode and processes continuous batches without quality degradation. Your operation supports 24-hour continuous working with minimal downtime. The stepless sawing feed speed adjustment optimizes throughput for varying project requirements.
Complete Process Integration
You benefit from an end-to-end solution combining feeding, straightening, sawing, threading, and grinding. The hydraulic clamping system ensures zero movement during processing. Flat sawing ends eliminate secondary operations, while automated grinding delivers burr-free surfaces that won't damage sleeves.
Application Scenarios
Large-Scale Infrastructure Projects
Your Fully Automatic CNC Rebar Threading Production Line excels in high-speed rail pre-cast segment production where thread precision directly impacts seismic resistance. The standardized threading ensures structural longevity in bridge engineering applications spanning multiple decades.
Nuclear and Energy Sectors
For nuclear power containment structures, you achieve high-tensile connections withstanding extreme pressure and corrosive environments. The controlled processing environment maintains thread consistency critical for safety compliance in hydropower projects.
Urban Construction Solutions
In restricted urban subway and tunneling zones, the compact automated design enables efficient on-site processing. You deliver high-volume coupling solutions for diaphragm walls and deep foundation pits where manual threading proves logistically impossible.
Commercial Processing Centers
Rebar processing and distribution centers leverage the system's versatility across multiple diameter ranges. Fast model changeover and strong compatibility maximize your facility's service offerings to diverse construction clients.
Quality Assurance
Dimensional Precision Standards
Your production undergoes rigorous Go/No-Go gauge testing for thread pitch and diameter consistency. The Ra surface roughness value and rib-stripped section parallelism meet international mechanical splicing standards. Each threaded joint demonstrates tensile strength exceeding base metal specifications.
System Stability Testing
The production line completes 72-hour continuous load testing before deployment. Sensor calibration ensures the CNC feedback loop correctly manages hydraulic pressure fluctuations. This prevents thread deformation during high-speed rolling cycles across varying rebar grades including HRB500.
Long-Term Reliability
With maintenance cycles extending to 3,000 threads per die inspection and 10,000 threads before replacement, your operational costs remain predictable. The closed-loop water-soluble oil cooling system prevents thermal deformation during extended production runs.
Frequently Asked Questions
Q: How does the system maintain thread quality across different rebar batches?
A: The automatic diameter compensation algorithm adjusts processing parameters based on real-time sensor data. This ensures consistent thread profiles regardless of minor variations in incoming material specifications.
Q: What maintenance schedule should we follow?
A: Inspect rolling dies every 3,000 threads and plan replacement or regrinding every 10,000 threads depending on rebar grade. Regular hydraulic system checks and cooling fluid replacement maintain optimal performance.
Q: Can the line accommodate international threading standards?
A: Yes. The CNC software supports rapid switching between Metric, Whitworth, and ASTM thread profiles. You simply change the rolling head and select the corresponding program through the touch panel interface.
Q: How many operators does the production line require?
A: Due to full automation, a single operator monitors the CNC console and manages raw material loading. This represents significant labor savings compared to manual or semi-automatic alternatives.
Q: What thread diameter range does the equipment handle?
A: The Product processes rebars from Φ16 to Φ50 mm. The system's versatility supports diverse project requirements without additional equipment investment.
Q: How do you prevent overheating during continuous operation?
A: Our closed-loop water-soluble oil cooling system provides high-pressure lubrication and heat dissipation directly at the threading point. This maintains dimensional stability during 24-hour production cycles.
