Product Description
Spiral Rebar Bending Machine – High-Precision CNC Equipment for Industrial Steel Processing
Modern infrastructure projects demand precision and efficiency in rebar fabrication. The spiral rebar bending machine from Shandong Zhongji Luyuan Machinery Co., Ltd. delivers enterprise-grade automation for your steel processing needs. Our CNC-controlled equipment processes rebar diameters from φ10–32mm with bidirectional bending capabilities and φ36–50mm for single bending operations.
With a bending angular speed of 48°–72°/s and moving speed up to 1m/s, this machine achieves production rates of 110–180 pieces per hour. The double-head synchronous bending system ensures angle precision within ±0.5° and length accuracy under 1mm. Powered by a 27.7kW system with actual consumption of just 12kW/h, it delivers energy-efficient performance for continuous 24-hour operation in demanding construction environments.
What Makes Our Spiral Rebar Bending Machine Stand Out
You get a fully automated CNC processing center that eliminates manual intervention entirely. The PLC touch screen control system stores processing parameters for instant recall, allowing quick specification switching between projects.
Our vertical bending design saves valuable factory floor space. The heavy-duty steel welded frame withstands continuous industrial use without structural deformation. Servo motor drive systems maintain consistent performance across extended production cycles.
The equipment handles complex shapes including right angles, hooks, stirrups, and custom configurations. One operator can replace 5–8 manual workers while reducing material waste by over 10%. New staff master the intuitive interface within just one hour of training.

Critical Applications in Infrastructure Projects
Your construction projects benefit from this spiral rebar bending machine in three key scenarios. Bridge engineering teams use it for fabricating spiral stirrups in massive piers and pylons where precise pitch ensures seismic resistance standards.
Geotechnical foundation work relies on the machine for continuous cages in large-diameter bored piles. The equipment processes high-tensile steel without fracturing even in soft-soil environments.
Tunnel and subway projects utilize the system for curved reinforcement segments in shield tunnel construction. The machine maintains consistent curvature despite fluctuating ambient temperatures and humidity in confined precast factory environments.
High-rise building foundations require dense spiral ties for reinforced concrete columns. The equipment delivers seismic-compliant results in restricted spatial conditions where manual methods fail.
Key Performance Advantages
You achieve one-step forming with ultra-high precision across all operations. The double-head synchronous bending system completes complex shapes in single passes, dramatically reducing production time.
The PLC control stores unlimited parameter sets. You switch between specifications with one-key recall, eliminating setup delays between batches.
High-strength HRB400 and HRB500 grade rebars process smoothly through variable frequency drive systems. Adjustable torque settings prevent motor overload while maintaining consistent output quality.
The heavy-duty alloy steel rollers feature HRC 58-62 hardness ratings. This wear resistance ensures dimensional stability across millions of bending cycles.
Quality Assurance and Global Recognition
Our manufacturing adheres to ISO9001:2015 standards and CE certification requirements. Every spiral rebar bending machine undergoes rigorous stress testing before shipment.
Established in 2016 with RMB 50 million registered capital, Shandong Zhongji Luyuan serves leading construction enterprises including China Railway Group, CRCC, CSCEC, and CCCC. Our equipment supports projects across nearly 100 countries in high-speed rail, nuclear power, hydropower, and urban infrastructure sectors.
The dual-drive synchronous roller system eliminates pitch inconsistency issues common in competitor models. Zero-slip feeding maintains precision even during high-volume production runs.
Operational Efficiency and Cost Savings
You reduce labor costs immediately with single-operator functionality. The intelligent safety protection system allows unsupervised operation during continuous production cycles.
Material waste drops by over 10% compared to manual processing methods. Precise angle control and length accuracy minimize rework and scrap rates.
The modular design simplifies maintenance procedures. Critical components like rollers, blades, and sensors use standardized replacement parts readily available in our global service network.
Remote PLC diagnostics capability means your technical team resolves issues without equipment downtime. Our support staff accesses your control system parameters to troubleshoot problems during peak construction phases.
Frequently Asked Questions
Q: How does the machine accommodate different rebar grades?
A: The variable frequency drive and adjustable torque settings handle varying yield strengths from HRB400 to HRB500 without motor stress. You simply input material specifications through the touch screen interface.
Q: What causes pitch inconsistency in spiral production?
A: Slip in the feeding mechanism creates irregularities. Our dual-drive synchronous rollers ensure zero-slip feeding throughout the bending process, maintaining consistent pitch across entire production runs.
Q: Can your equipment produce non-standard helical shapes?
A: Yes, the CNC control system features multi-point programming. You customize variable radii within single continuous spirals for specialized engineering requirements.
Q: What maintenance schedule do you recommend?
A: Filter hydraulic fluid every 500 operating hours and perform complete replacement at 2,000-hour intervals. This schedule maintains optimal system pressure and component longevity based on industrial stress testing data.
Q: How quickly can operators learn the system?
A: New personnel achieve proficiency within one hour of training. The intuitive touch screen interface and parameter storage functions minimize learning curves.
Q: Does the machine handle extreme environmental conditions?
A: Climate-controlled electrical cabinets and heavy-duty lubrication systems maintain performance in temperature fluctuations and high humidity environments common in tunnel and foundation work.
