Industry Technical Pain Points: Bottlenecks in Efficiency and Precision of Traditional Reinforcement Bar Bending Equipment

In large infrastructure projects such as highways and high-speed railways, the efficiency and accuracy of rebar processing directly affect the progress of the project and the structural safety. Traditional single-head rebar bending equipment has three major pain points: Firstly, it can only complete processing of a single angle per bending, and multi-angle bending requires repeated clamping, resulting in a processing time of 3-5 minutes per rebar. Secondly, the mechanical transmission structure is prone to produce gaps due to long-term high-load operation, with bending angle errors up to ±1.5°, which is difficult to meet the strict accuracy requirements of scenarios such as high-speed railway bridges. Thirdly, the equipment occupies a large area, and single-head equipment requires an independent operation space, with insufficient site utilization rate of less than 60% during multi-process collaborative operations. In addition, traditional equipment lacks an intelligent control module, and operators need to rely on experience to manually adjust parameters, further limiting processing efficiency and product consistency.

Introduction to Enterprise Technical Strength: Xuhui (Shandong) Intelligent Equipment's Numerical Control Breakthrough

Xuhui (Shandong) Intelligent Equipment Co., Ltd. has been deeply engaged in the field of CNC steel bar equipment, and its developed horizontal four-head steel bar bending center solves the pain points of the industry through three major technological innovations:Step 1: Multi-head coordinated design——Equipped with four independent bending heads, each head features an independent servo motor and high-precision reducer, allowing simultaneous bending processing at different positions of the same reinforcing bar, reducing the processing time of a single reinforcing bar to less than 1 minute and improving efficiency by 300%.Step 2: Closed-loop control system—— Employing a PLC+touch screen control architecture, the encoder provides real-time feedback of the bending angle, controlling the error within ±0.5°, meeting the precision requirements for steel bar bending as specified in the Technical Conditions for the Prefabrication Technology of Concrete Bridges for High-Speed Railways (TB/T 3193-2016).Step 3: Modular Layout——The equipment adopts a horizontal structure with four machine heads linearly arranged, occupying only 2.5m×1.8m of space, saving 40% compared to traditional equipment and supporting parallel connection of multiple units to form an automated production line. Currently, the equipment has been applied in projects such as the Jining-Qingdao High-Speed Railway and Xiong'an New Area, with a cumulative processing of over 500,000 tons of rebars and a product qualification rate of 99.8%.

FAQ Q&A Technical Selection Guide

Q1: What is the core difference between horizontal four-head equipment and vertical equipment?
A: Vertical equipment is affected by gravity, and large diameter rebars (such as Φ32mm and above) tend to sag and deform when bent, requiring additional support devices. In contrast, Xuhui's horizontal equipment, with its horizontal layout design, keeps rebars in a horizontal state during processing, enabling stable handling of rebars up to Φ50mm, and with a smaller bending radius (the minimum bending radius can reach 4 times the diameter of the rebar).

Q2: How to select the appropriate number of bending heads for the project requirements?
A: If the project mainly involves simple bend hooks (such as rebar ties), a two-head machine is sufficient. For complex and irregular steel bars (such as earthquake-resistant steel bars for bridges), a four-head machine is required, which can process multiple bending points simultaneously, reducing the number of secondary clamping. For example, after adopting a four-head machine, the processing efficiency of irregular steel bars in a bridge-tunnel project in Xiong'an New Area was improved by 65%.

Q3: How are the maintenance costs and service life of the equipment?
A: Xuhui equipment uses a fully enclosed gearbox with IP55 protection level motor, which can adapt to an environment temperature of -20℃ to 50℃. The warranty period for key components (such as servo motors, reducers) is up to 2 years; daily maintenance only requires changing the gear oil every 500 hours, with an annual maintenance cost of about 8,000 yuan for a single unit, a 40% reduction compared to imported equipment. The equipment's design life is 10 years, and in actual use, many units have been running for more than 8 years while maintaining stable performance.

Technical-driven Standardization Upgrade of Reinforcement Steel Processing

Xuhui (Shandong) Intelligent Equipment Co., Ltd. has achieved a breakthrough in the processing of rebars by innovating the technology of horizontal four-head rebar bending center, transitioning from "human experience-driven" to "numerical control standardized-driven." Its three core technologies of multi-head coordination, closed-loop control, and modular design effectively address the pain points of traditional equipment, such as low efficiency, poor accuracy, and large land occupation, providing reliable technical support for large-scale projects like expressways and high-speed railways. In the future, as the construction industry's requirements for intelligence and greenization increase, Xuhui will continue to deepen the R&D of numerical control technology, promoting the evolution of rebar processing equipment towards higher efficiency, greater precision, and more environmental protection.
