The Steel Cage Rolling Welding Machine (also known as Steel Cage Forming Machine) is an automated steel bar processing equipment based on a PLC numerical control system. It is specially designed for the standardized production of steel cages in large-scale infrastructure projects such as bridges, high-speed railways, expressways, subways, and utility tunnels. By replacing the traditional manual binding process with intelligent control, the equipment realizes the synchronous winding and precise welding of main bars and stirrups, fundamentally solving the pain points of manual processing such as low efficiency, unstable quality, and material waste. Integrating 12 core components including traction guide rails, intelligent control console, main bar material rack, and hydraulic support device, the equipment adopts welding control technology with independent intellectual property rights. It can adapt to the processing needs of steel cages with different pile diameters and lengths, and is a core equipment for improving construction efficiency and quality in modern infrastructure projects.

Core Advantages
Efficient Production & Doubled Capacity: Equipped with a fully automatic welding manipulator and a stepless speed regulation rotating system, the equipment only takes 1-2 seconds to weld a single weld. Its production efficiency is 3-4 times higher than that of traditional manual work.
Stable Quality & Exempt from Supervision Inspection: The numerical control system synchronously controls the rotating speed and moving speed of the rotating disc through PLC programming, ensuring uniform distribution of main bars. The consistency deviation of the steel cage diameter is controlled at the millimeter level.
Cost Optimization & Efficiency Improvement: The average power consumption of different models is only 4-10kw/h, and the electricity cost for processing per ton of steel bars is as low as 15-20 yuan, which is much lower than the industry average.
Flexible Adaptation & Easy Operation: The equipment supports the adjustment of multiple specification parameters, and can process steel cages with a pile diameter of 300-2500mm and a length of 12-27 meters.
Working Principle
Main Bar Fixing: Manually pass the main bar through the template hole of the fixed rotating disc, extend it to the corresponding hole of the movable rotating disc, and lock it in place.
Stirrup Welding Start: Weld and fix the end of the coiled bar (stirrup) on a main bar, and set the welding parameters and stirrup spacing through the console.
Synchronous Welding: After the numerical control system is started, the fixed rotating disc and the movable rotating disc rotate synchronously. While driving the main bar to rotate, the movable rotating disc moves backward at a constant speed, so that the stirrup is evenly wound around the main bar. The fully automatic welding torch completes the welding operation synchronously according to the program-set points.
Finished Product Forming: The equipment stops automatically after welding is completed. The formed steel cage can be taken out by loosening the fixing device. The whole process realizes semi-automatic operation of "one-key start after parameter setting".
