CNC Rebar Stirrup Bending Machine – Enterprise-Grade Automated Reinforcement Solution

Shandong Zhongji Luyuan Machinery Co., Ltd., established in 2016 with a registered capital of RMB 50 million, introduces its heavy-duty cnc rebar stirrup bending machine engineered for precision and productivity. This enterprise-level system processes rebar ranging from φ12–50 mm with a bending angle accuracy within ±0.5° and length error under 1 mm. Capable of producing 80–120 stirrups per hour, the machine operates on a fully automatic servo CNC platform with horizontal synchronized bending technology.

Your processing line can handle continuous bending lengths from 0.5 to 12 meters. With Model LYWQ-32's dual-head synchronous operation and 12.6KW power efficiency, you replace 5–8 manual workers with just two operators. This system has been proven across high-speed railways, bridge engineering, and nuclear power projects in nearly 100 countries.

Why Automated Stirrup Bending Transforms Your Production

Manual rebar bending drains your budget and compromises quality. Labor costs continue rising, while measurement errors lead to material wastage exceeding 10% on many job sites. Traditional hydraulic machines lack the repeatability your structural projects demand.

Your construction timelines need precision and speed. When producing stirrups for bridge pier columns or seismic-resistant high-rise foundations, dimensional consistency directly impacts structural integrity. A cnc rebar stirrup bending machine delivers geometric accuracy that manual methods cannot match.

You gain immediate ROI through labor reduction. The PLC touch-screen interface stores parameters for instant specification switching. New operators master the system within one hour, eliminating lengthy training costs.

Technical Specifications – LYWQ-32 Model

Core Performance Advantages

Precision You Can Measure

Your structural engineers specify tight tolerances for a reason. This system delivers bending angle errors within ±0.5° and length deviations under 1mm. Such precision ensures every stirrup meets load-bearing requirements for bridge girders and seismic-resistant reinforcement cages.

Dual-Head Efficiency

Double-head synchronous bending processes multiple rebars simultaneously. You achieve one-step forming without repositioning material. This design doubles throughput compared to single-head systems while maintaining consistent quality across every piece.

Intelligent Operation

The PLC touch screen stores unlimited parameter sets. You switch between stirrup specifications with one-key recall. This feature proves essential when your projects require multiple stirrup types within the same production shift.

Heavy-Duty Construction

The robust steel structure withstands 24-hour continuous operation. High-torque servo drives handle φ6–50mm high-strength rebar without performance degradation. You experience minimal downtime in demanding precast concrete factory environments.

Labor Optimization

One operator replaces 5–8 manual workers. You eliminate repetitive manual handling while reducing workplace injury risks. The intuitive interface requires just one hour of training for new staff.

Material Conservation

Automated measurement and cutting reduce rebar waste by over 10%. Your material costs decrease significantly on large-volume projects. Precise cutting eliminates the scrap accumulation common with manual methods.

Operational Flexibility

You process deformed bars, round bars, right angles, hooks, and complex special-shaped reinforcements on the same machine. This versatility supports diverse project requirements without equipment changes.

Application Scenarios for Maximum Impact

Large-Scale Infrastructure

Your bridge and highway projects demand consistent stirrup quality for pier columns and girders. This cnc rebar stirrup bending machine operates reliably in dusty outdoor environments where manual teams struggle with precision. The 12-meter bending length accommodates extra-long stirrups for massive structural elements.

Precast Concrete Manufacturing

High-volume prefabricated component production requires 24/7 reliability. You achieve standardized stirrup output for wall panels, beams, and columns. The 80–120 units/hour capacity matches assembly line speeds in modern precast facilities.

Seismic Engineering

Earthquake-resistant foundations need multi-angle bends and hooks that manual bending cannot reliably produce. You program complex geometries into the CNC system for exact replication. This capability proves critical when building codes demand specific reinforcement configurations.

Railway and Transit Systems

Underground utility corridors and urban rail projects require stirrups meeting strict safety tolerances. Your production maintains the dimensional consistency that inspection teams verify. The machine's proven performance supports projects for China Railway Group and similar enterprises.

Quality Assurance Through Rigorous Control

Component Durability

Straightening rollers feature HRC 58-62 surface hardness using high-alloy tool steel. You avoid frequent roller replacements that interrupt production. Tungsten carbide cutters maintain edge sharpness through thousands of cutting cycles.

System Synchronization

Advanced servo encoders provide real-time feedback preventing cumulative length errors. You maintain accuracy even during extended production runs. The traction motor's heat dissipation system ensures stable performance under continuous load.

Spring-Back Compensation

The CNC software automatically adjusts for rebar spring-back behavior. Different steel grades exhibit varying elastic recovery—your machine accounts for these material properties. This intelligent compensation eliminates the trial-and-error adjustments manual operators require.

Continuous Testing Protocols

Each machine undergoes the Continuous Bending Accuracy Test measuring angle consistency over 500-unit runs. You receive equipment proven to maintain specifications throughout typical production volumes. The pneumatic cutting system's response time meets industrial benchmarks for clean, burr-free cuts.

Frequently Asked Questions

Q: What rebar diameters can this machine process simultaneously?

A: You process multiple bars depending on diameter—for example, 7 bars of φ10mm or 2 bars of φ25mm in one cycle. The LYWQ-32 model accommodates single bars up to φ32mm, making it suitable for both light stirrups and heavy-duty reinforcement.

Q: How quickly can operators switch between different stirrup specifications?

A: Your operators recall stored parameters with one touch. The PLC system retains unlimited specification sets, allowing instant transitions between projects. This eliminates manual recalibration time when production schedules demand flexibility.

Q: What level of technical training do operators need?

A: New operators become proficient within one hour of hands-on training. The intuitive touch-screen interface uses visual guides and error prompts. Your workforce adapts quickly without requiring specialized CNC programming knowledge.

Q: Can this machine handle complex shapes beyond standard stirrups?

A: Yes—you produce right angles, hooks, and custom special-shaped reinforcements. The 0–180° continuous angle control and programmable bending sequences support architectural and structural engineering requirements for irregular geometries.

Q: What maintenance schedule does the machine require?

A: Your maintenance team performs routine inspections every 500 operating hours. The torsion-resistant structure and servo drive system exhibit low failure rates. Critical wear components like cutters and rollers have replacement intervals clearly defined in documentation.

Q: How does this system reduce material waste?

A: Automated measurement eliminates the human errors that cause scrap. You achieve over 10% waste reduction compared to manual methods. Precise cutting to programmed lengths means every piece of rebar contributes to finished product rather than scrap bins.

Q: Is the machine suitable for outdoor construction sites?

A: The heavy-duty construction withstands demanding environments including dusty job sites. However, you maximize equipment lifespan by providing basic weather protection. Many customers install the machine under temporary shelters at large infrastructure projects.

Q: What power requirements does installation demand?

A: You need 380V three-phase electrical supply at 50Hz frequency. The 12.6KW power consumption remains efficient compared to hydraulic systems. Your facility's electrical infrastructure typically accommodates these specifications without upgrades.
