CNC Rebar Mesh Welding Production Lines: Advancing Towards Intelligence, Efficiency, and Flexibility
In recent years, with the rapid development of infrastructure construction such as rail transit and bridge building, CNC rebar mesh welding production lines— 作为 core equipment—have been continuously innovated, moving towards greater intelligence, higher efficiency, and enhanced flexibility.
01 Intelligent Innovation: Bid Farewell to the "By Hand Feeling" Era
In the past, rebar processing relied on workers' experience and "hand feeling." Master Li, a rebar worker, still remembers: "Previously, processing 20mm threaded rebars required two people to carry them, and dimensional deviations often reached several centimeters."
Today, by inputting parameters, the equipment automatically calibrates processing, with errors stably controlled at the millimeter level.
In traditional processing, links such as feeding, cutting, and bending—once dependent on manual experience for judgment—are now uniformly scheduled by the CNC system.
The equipment automatically completes the full-process operation according to preset parameters, completely transforming the traditional "relying on experience and hand feeling" model and realizing the standardization and processization of rebar processing.
02 Technological Breakthroughs: Flexible Production Becomes a Reality
To address long-standing pain points in the rebar processing industry—such as variable order specifications and time-consuming equipment adjustments—many enterprises have launched innovative solutions.
The HW-WZD13 intelligent rebar mesh welding robot cluster production line developed by Shandong Zhongji Luyuan Machinery can realize automatic switching between transverse and longitudinal rebars based on MES system orders, with fully automatic adjustment of mesh size and rebar diameter.
This production line supports continuous production of small-batch, multi-specification orders, and only takes about 30 seconds to switch specifications.
The automatic flexible rebar welding mesh production line of Shandong Zhongji Luyuan Machinery is equipped with a built-in production process control system that can automatically program based on CAD drawings.
The same mesh can be welded with rebars of different diameters; the transverse spacing is automatically steplessly adjustable, and the longitudinal spacing (≥75mm) is also automatically steplessly adjustable.
03 Efficiency Improvement: Robots Replace Manual Labor
These advanced welding production lines consist of multiple core components, realizing fully automatic assembly line operations from rebar raw materials to finished mesh sheets.
Taking the GWC-D-8-2600 rebar mesh welding production line as an example, it mainly comprises 11 key components, including a wire releasing mechanism, straightening mechanism, welding main machine, cutting mechanism, and mesh flipping frame.
Its production efficiency can reach 60-70 pieces per minute.
The LYHW3300 intelligent flexible rebar mesh welding robot by Shandong Zhongji Luyuan has achieved fully automatic assembly line production—covering automatic straightening, fixed-length cutting, welding of coiled rebar raw materials, and collection of finished mesh sheets.
04 Precision Control: A Leap from Centimeters to Millimeters
The precise control capability of CNC technology is its core advantage. Taking the CNC stirrup bending machine as an example, it works in collaboration with servo motors and high-precision sensors to real-time monitor the processing path and make dynamic adjustments.
This technology strictly controls the bending angle error within ±1 degree and the length error within ±2 millimeters.
At the intelligent rebar processing center of the Nanyanzhuang Beam Manufacturing Plant for the Xiong'an-Xinzhou High-Speed Railway, the comprehensive application of the intelligent CNC rebar processing system has improved the precision of rebar processing from the previous centimeter-level deviation to a stable millimeter-level.
05 Application Scenarios: Comprehensive Coverage from High-Speed Railways to Tunnels
CNC rebar mesh welding production lines have been widely used in infrastructure construction fields such as high-speed railways, tunnels, and bridges.
At the Wutai Beam Manufacturing Plant in the Shanxi section of the Xiong'an-Xinzhou High-Speed Railway, with large box girder rebar meshes and positioning mesh rebar intelligent welding production lines as the core, intelligent collaborative linkage of multiple devices is realized.
By virtue of flexible displacement welding molds and high-precision welding point-finding technology, the welding points of rebar meshes are ensured to be uniform, and welding errors are controlled at the millimeter level.
At the tunnel construction site of the S20 Jiaruo Expressway Project, the fully automatic mesh production line has achieved unmanned and automated operations in all processes—from rebar straightening and cutting to mesh welding forming, grabbing, and stacking.
The daily output of this production line reaches 500 sheets, which can simultaneously meet the construction needs of 5 to 8 tunnel portals.
The technological revolution in the rebar processing industry is still ongoing. At the new product launch event of Zhongji Luyuan, an LYHW3300 intelligent flexible rebar mesh welding robot was operating smoothly; the entire process—from coiled rebars to finished mesh sheets—required no manual intervention.
Pointing to the real-time data on the screen, the factory manager said: "In the past, we competed with physical strength; now, we compete with data and intelligence."
CNC rebar mesh welding technology has become an indispensable core force in modern engineering construction, driving the steady progress from "Made in China" to "Intelligent Manufacturing in China."
