Xuhui (Shandong) Intelligent Equipment Co., Ltd. is one of the leading manufacturers and suppliers of bridge steel cage forming equipment in China. If you're going to wholesale high quality bridge steel cage forming equipment made in China, welcome to get quotation from our factory. Customized orders are welcome.
This bridge rebar cage forming machine is a highly efficient and intelligent steel bar processing device, specially designed for infrastructure projects such as bridges, buildings, and tunnels, enabling automated production of rebar cages.
Compared with the old manual welding methods, it uses a CNC system to precisely control the entire welding process. Not only does it double production efficiency, but the rebar cages produced are highly consistent in size and quality, while also saving significant labor and material costs and reducing waste.
Equipment Structure and Working Principle
This Bridge Steel Cage Forming Equipment is mainly composed of a main frame, a rotary drive system, a feeding mechanism, a welding unit, and a CNC control console.
During operation, the main rebars are automatically arranged and fed through the feeding mechanism, then driven by servo motors to rotate synchronously with the turntable. The stirrup (spiral) bars are pulled from the coil rack and wound helically around the main rebars. The machine then follows the preset program to activate fully automatic welding, carrying out simultaneous welding at multiple points to ensure every joint is firmly welded.
The entire process is controlled by the CNC system, which allows real-time adjustment of parameters such as turntable speed and welding point spacing, making it easy to produce rebar cages of various specifications.

Product Preparation Work
This rebar cage rolling welding machine is the real "workhorse" on construction sites for connecting steel bars. As long as it's operated according to the proper procedures, the welds will be stable and strong, the machine will last for many more years.
- Equipment Inspection：Before powering on, walk around the machine and give it a careful check: make sure the power supply is firmly connected and the cables are not worn or damaged. Rotate the rollers and electrode wheels to see if they run smoothly, and check whether any bolts on the frame are loose. Fix small issues in advance-don't wait until the job is halfway done and something goes wrong.
-
Parameter Confirmation：Confirm the diameter of the rebars to be welded, then set the welding current, voltage, and speed to the corresponding values. With the correct parameters, the welded joints will be strong and reliable, and problems are far less likely to occur.
-
Rebar Pre-treatment：Clean rust and oil from both ends of the rebars, grinding them down to expose a clean, shiny metal surface. Welding with contaminants still on the rebar can easily lead to weak welds or slag inclusion, which means more trouble and rework later on.
Product Highlights
- This machine is equipped with high-precision servo motors and a PLC control system. Working together, they enable synchronized completion of main rebar positioning, stirrup winding, and welding in a single continuous process, with overall accuracy controlled within ±1 mm. This effectively eliminates deformation and misalignment issues commonly caused by manual operation.
- It supports processing main rebars with diameters from φ12 to φ32 mm and stirrups from φ6 to φ12 mm, easily handling both multi-batch production and varying specification demands, offering excellent production flexibility.
- The equipment can automatically adjust current and voltage, optimizing welding parameters based on rebar diameter and material. The resulting weld strength fully meets standard requirements while also helping reduce energy consumption.
Industry Development Trend
With the rise of prefabricated construction, CNC rebar cage rolling welding machines are evolving toward greater intelligence and energy efficiency.
This equipment offers high precision and low energy consumption, gradually replacing the old manual methods of making rebar cages. Today, for large-scale infrastructure projects, having one is almost a must.
Its reliability has already been proven in numerous national-level projects. As infrastructure projects continue to expand across the country, this machine has become the mainstream choice in the field of intelligent rebar processing.
