Product Description
Fully Automatic Bar Bending Machine – Enterprise-Grade CNC Rebar Processing Solution
Shandong Zhongji Luyuan Machinery Co., Ltd., established in 2016 with a registered capital of RMB 50 million, delivers industrial-grade fully automatic bar bending machine solutions engineered for high-volume infrastructure projects. Our CNC Vertical Rebar Bending Center processes φ10–32mm rebar with ±0.5° angle precision and less than 1mm length deviation. Achieving production efficiency of 100–150 pieces per hour, this servo-driven system replaces 5–8 manual workers while reducing material loss by over 10%. With exports to nearly 100 countries and trusted partnerships with China Railway Group and CSCEC, our equipment delivers 24-hour continuous operation stability for modern steel reinforcement processing centers.
Why Choose Our CNC Vertical Rebar Bending Center
You need a solution that eliminates labor bottlenecks while maintaining structural precision. Traditional manual bending creates inconsistent angles and high safety risks.
Our double-head synchronous bending technology forms complex shapes in one step. The PLC touch screen controller stores unlimited parameter sets, allowing you to switch between stirrups, hooks, and special-shaped reinforcements instantly.
New operators master the system within one hour. The vertical design saves 40% floor space compared to horizontal models. You'll achieve Rockwell HRC 58-62 hardness on bending mandrels, ensuring long-term durability even when processing high-strength deformed bars continuously.

Core Performance Advantages
You face tight construction deadlines with zero tolerance for dimensional errors. Our servo positioning system ensures every beam, column, and shear wall reinforcement meets seismic building codes.
The dual-traction feeding mechanism prevents bar slippage during high-speed processing. Vacuum-quenched alloy steel mandrels deliver 50,000+ bending cycles before requiring adjustment.
When you program complex cage geometries, the memory function recalls patterns instantly. This eliminates manual recalibration between production runs.
The IP54-rated electrical cabinet protects PLC components in dusty concrete environments. Centralized lubrication systems maintain moving parts without daily manual intervention. You'll achieve consistent output whether processing galvanized rebar for coastal projects or epoxy-coated bars for highway bridges.
Proven Applications Across Major Infrastructure
Your fully automatic bar bending machine adapts to multiple high-stress environments:
Prefabricated Concrete Factories: Process standardized stirrups for modular housing at speeds that manual teams cannot match. The one-step forming reduces assembly errors in production lines.
High-Speed Rail and Bridge Construction: Mobile container-mounted units deliver precision bending for tunnel support structures and bridge pier cages, maintaining accuracy despite temperature fluctuations.
Large-Scale Civil Engineering: Handle heavy-gauge foundation bars for skyscraper projects where structural integrity depends on exact rebar skeleton dimensions, even during 24/7 shift operations.
Our equipment supports nuclear power projects, hydropower dams, and underground utility corridors where reinforcement failure is not an option. Long-term partnerships with China Communications Construction Company and China Nuclear Industry Construction Corporation validate our reliability in mission-critical applications.
Operational Efficiency and Cost Reduction
You spend too much on labor while struggling with material waste. This system requires only one operator to achieve output that previously needed an eight-person crew.
Manual measurement errors cause over 10% rebar loss in traditional workflows. Our CNC controller eliminates human calculation mistakes, directly improving your bottom line.
The touch panel interface allows parameter entry in minutes. Store geometric data for circular columns, rectangular beams, and irregular wall sections. Recall saved patterns with one button press when project specifications repeat.
Safety interlocks prevent operation when guards are open. Emergency stop response activates within 0.3 seconds, protecting both operators and equipment investment.
Quality Standards and Long-Term Reliability
You need equipment that maintains precision through years of continuous use. Our heavy-duty frame resists torsional deformation under maximum load conditions.
The servo drive system delivers consistent torque across the full bending range. Low failure rates reduce unplanned downtime, keeping your processing plant operational during peak demand.
We engineer components to ISO9001:2015 and CE certification standards. Electrical safety testing includes surge protection verification and PLC stress tests that simulate years of command inputs.
When you inspect delivered units, conduct the 48-72 hour continuous operational fatigue test. Our machines maintain hydraulic pressure without leaks and servo motors run cool even under sustained maximum-speed bending cycles.
Frequently Asked Questions
Q: What is the maximum rebar diameter this equipment can process?
A: Standard models handle up to φ32mm for bi-directional bending and φ50mm for single-direction operations. Stirrup-specific configurations optimize performance for φ10–12mm dual-wire processing.
Q: How often do cutting blades require replacement?
A: High-quality alloy blades typically need flipping or replacement after 20,000 to 50,000 cuts, depending on rebar grade and hardness. We recommend tracking cut counts through the PLC's built-in counter.
Q: Can the system process galvanized or epoxy-coated rebar without damaging protective layers?
A: Yes. Adjust bending mandrel pressure settings to prevent coating abrasion. This maintains corrosion resistance for coastal or chemical exposure environments.
Q: What power supply does the machine require?
A: Installation requires 3-phase industrial power at 380V/50Hz to provide sufficient torque for heavy-duty operations. Total connected load is 27.7kW with actual consumption around 12kW per hour during active processing.
Q: How do you maintain equipment in dusty construction sites?
A: IP54-rated enclosures protect electrical components from concrete dust. Centralized lubrication systems automatically service moving parts. Daily compressed air cleaning of feed rollers prevents debris buildup.
Q: What is the learning curve for new operators?
A: Most technicians achieve full operational competency within one hour due to the intuitive touch screen interface and guided parameter entry system.
