Fully Automatic Steel Bar Bending Machine Becomes Core Equipment for Infrastructure as Intelligent Transformation Accelerates
2025/12/09 09:09
As China's infrastructure industry accelerates its shift towards intelligence, fully automatic steel bar bending machines are gradually replacing traditional manual processing methods and becoming core equipment for projects such as housing construction, bridges and high-speed railways. Reporters learned from multiple sources including China Construction Third Engineering Bureau's Wuhan Metropolitan Circle Ring Project and Zhongji Luyuan Steel Bar Machinery Production Base that fully automatic steel bar bending machines equipped with PLC numerical control systems not only increase processing efficiency by 8-10 times but also achieve millimeter-level precision control, effectively solving the pain points of traditional processes such as "low efficiency, large errors and difficulty in hiring workers".
The application effects in key projects have become an industry weathervane. Recently, the intelligent production line for prefabricated beam steel bars independently developed by China Construction Third Engineering Bureau was put into use in the Wuhan Metropolitan Circle Ring Project, among which the core equipment - fully automatic steel bar bending machine - has attracted widespread attention. "Traditionally, processing 1,000 standard stirrups manually required 8 workers to spend a whole day. Now, one equipment with one operator can complete the task in 8 hours, with a qualification rate of 100%," the project manager introduced. The equipment adopts a multi-dimensional straightening system and continuous bending technology, reducing errors by 60% compared with traditional equipment and achieving a labor substitution rate of 70%, helping to double the production efficiency of prefabricated beams.
Enterprise technological innovation continues to strengthen equipment competitiveness. The fully automatic steel bar bending machine recently launched by Shandong Zhongji Luyuan Machinery has occupied the mainstream market with its "high efficiency + precision + durability" characteristics. According to its technical director, the equipment is equipped with a high-precision servo motor and a full-closed-loop control system, which can realize integrated operations of straightening, bending, cutting and counting. It can process 12-15 standard stirrups per minute, with a maximum daily output of 12,000 pieces, which is 8-10 times that of traditional manual work. In terms of precision control, the length error is stably within ±1mm, and the bending angle is accurate to ±0.5°, which is far better than industry standards and effectively reduces material waste.
Durability and adaptability have become the keys to equipment popularization. The body of this equipment from Zhongji Luyuan Machinery is made of thickened steel plates through integral welding, and the core components are quenched. Its service life can reach 8-10 years in complex construction site environments such as dust and vibration. At the same time, it supports the processing of various materials such as Φ5-Φ16mm coiled round steel and deformed steel bars, can store hundreds of graphic schemes, and easily switch between stirrup types such as rectangular, circular and special-shaped, adapting to the needs of multiple scenarios such as high-speed rail guardrails and prestressed anchors. "From square stirrups in housing construction projects to oval stirrups in prefabricated component factories, one equipment can handle it all," said the person in charge of a prefabricated component factory in Hebei. After deployment, the annual labor cost is saved by more than 800,000 yuan.
Policy guidance and market demand drive industry expansion. With the implementation of the "Action Plan for the Coordinated Development of Intelligent Construction and New Construction Industrialization", many places have clearly required that the proportion of intelligent processing equipment in large-scale projects should not be less than 70%. Fully automatic steel bar bending machines have become essential equipment to meet the standards because they are compatible with BIM management systems. Data shows that since 2025, the penetration rate of this equipment in fields such as bridge engineering and prefabricated component factories has increased by 45% year-on-year, and the order volume of leading enterprises such as Zhongji Luyuan Machinery has increased by 60% year-on-year.
Industry analysts pointed out that fully automatic steel bar bending machines are transforming from "single processing equipment" to "intelligent production units". "In the future, equipment will pay more attention to data interaction and collaborative operations, and will link with steel cage rolling welding machines and sawing and threading equipment to form a production line, further improving the intelligence level of infrastructure processing," the analyst said. It is expected that the domestic market scale of fully automatic steel bar bending machines will exceed 1.5 billion yuan in 2026, becoming a core growth driver of infrastructure intelligence.
