CNC Automatic Iron Bar Bending Machine – Precision Vertical Rebar Processing Solution

Modern construction and infrastructure projects demand precision, speed, and reliability in reinforcement bar fabrication. Shandong Zhongji Luyuan Machinery Co., Ltd., established in 2016 with a registered capital of RMB 50 million, specializes in enterprise-grade CNC rebar processing equipment. Our iron bar bending machine features a vertical bowing framework able of handling φ10–32mm rebar with a bowing point extend of 0–180° and generation proficiency coming to 90–140 pieces per hour. With servo-controlled computerization and a preparing length extend of 0.5–12 meters, this machine conveys steady twisting exactness with point mistakes inside ±0.5° and length deviation beneath 1mm. Trusted by China Railroad, CRCC, and CSCEC, our hardware has been traded to about 100 nations worldwide.

Why Choose Our Vertical Iron Bar Bending Machine

You confront every day challenges on development destinations: manual twisting mistakes, conflicting points, labor deficiencies, and material waste. Our CNC programmed vertical bowing machine tackles these torment focuses effectively.

The double-head synchronous twisting framework forms different rebars at the same time. For φ10mm bars, you can twist 6 pieces at once. For φ20mm bars, 3 pieces per cycle. This significantly diminishes your preparing time.

Your administrators do not require specialized preparing. The PLC touch screen control framework is natural sufficient that modern laborers ace operation inside one hour. Parameter capacity permits speedy determination exchanging between diverse rebar sizes and twisting patterns.

Space imperatives? The vertical plan impression minimizes floor space necessities compared to even machines. You can introduce this hardware in tight workshop situations or swarmed development sites.

Technical Specifications

Multi-Bar Bending Capacity

Core Performance Advantages

Labor Cost Reduction

You need only one operator to replace 5–8 manual workers. The fully automatic processing eliminates physical strain and reduces labor intensity significantly.

Material Waste Minimization

Precision bending reduces rebar loss by over 10%. Consistent accuracy eliminates the common errors that occur in manual bending operations.

Superior Bending Accuracy

Heat-treated alloy steel mandrels with HRC 50-55 hardness ensure dimensional consistency. The servo drive system maintains angle precision across thousands of repetitive bends.

High-Volume Production

The double-head synchronous system completes one-step forming for stirrups, hooks, and complex special-shaped reinforcements. This configuration suits both precast concrete factories and on-site rebar processing centers.

24-Hour Continuous Operation

Heavy-duty machine body construction with torsion-resistant structure enables non-stop production. The robust gearbox and copper-wound motor maintain thermal stability during extended operation cycles.

Intelligent Control System

Store unlimited bending parameters in the PLC memory. Recall saved specifications instantly when switching between different project requirements. The digital interface displays real-time operation status and diagnostic alerts.

Primary Application Scenarios

High-Rise Construction Sites

You're managing multi-story building projects where seismic safety requirements demand high-volume stirrup production. Our iron bar bending machine delivers the consistency and speed necessary for structural integrity in earthquake-resistant designs.

Precast Concrete Factories

In controlled production environments, you manufacture bridge girders and modular housing units. The machine integrates seamlessly with automated production lines, creating complex reinforcement cages with repeatable precision.

Infrastructure and Civil Engineering

Dam construction, tunnel boring, highway bridges—these projects require processing high-tensile grade 60 rebar in harsh outdoor conditions. The equipment maintains bending accuracy and motor longevity despite extreme weather exposure.

Rebar Processing and Distribution Centers

You operate centralized processing facilities serving multiple construction sites. The wide diameter range (φ6–50mm) and quick specification switching enable efficient multi-client order fulfillment.

Quality Assurance Standards

Our manufacturing follows strict quality control protocols aligned with CE machinery directives and ISO 9001:2015 certification.

Hardness Testing

We verify metallurgical properties of center pins and bending bushes to prevent premature wear. This extends component lifespan and maintains consistent performance.

Dimensional Precision Testing

Each machine undergoes measurement across 100 consecutive bends. We guarantee angle deviation within ±1 degree throughout the equipment's operational lifetime.

Load Endurance Trials

24-hour continuous operation tests monitor gearbox temperature and motor thermal stability. This ensures reliability during your peak production periods.

Electrical Safety Audits

Insulation resistance and grounding tests meet international safety standards. Protective shields and emergency stop mechanisms comply with OSHA and CE requirements.

The high-density cast iron worktable provides vibration dampening during high-speed bending cycles. This structural rigidity protects internal components and maintains calibration accuracy.

Frequently Asked Questions

Q: What rebar grades can this machine process?

A: Standard models handle HRB335 and HRB400 rebar commonly used in construction. For HRB500 high-strength steel, we recommend our reinforced high-torque variant designed specifically for premium-grade materials.

Q: How often does the machine require maintenance?

A: Replace gearbox oil (ISO 220 grade) every 500 operating hours. Lubrication points need attention weekly. The servo system requires minimal maintenance—annual calibration checks are typically sufficient.

Q: Can I bend multiple bars of different sizes simultaneously?

A: Yes, for smaller diameters (φ10-14mm), you can process multiple bars in one cycle as shown in our capacity table. However, different diameter bars should not be mixed in a single bending operation to maintain precision.

Q: What causes angle drift during operation?

A: Belt slippage or worn limit switches are common culprits. Regular calibration of the digital encoder prevents this issue. Our technical team provides detailed calibration procedures in the operation manual.

Q: Is operator training included with purchase?

A: We provide comprehensive on-site installation and training. Your operators receive hands-on instruction until they achieve full operational proficiency. Remote technical support remains available throughout the equipment's service life.

Q: What safety features protect operators?

A: Mandatory protective shields cover the rotating work disk. Emergency stop pedals allow instant power cutoff. The machine includes entanglement prevention sensors and automatic shutdown protocols during anomalous operations.

Q: How does power consumption compare to hydraulic models?

A: Our servo-driven machine consumes only 12kW/h actual power despite 27.7kW total capacity. This efficiency results from intelligent power management—the system draws maximum power only during bending cycles, not idle periods.
