The CNC steel cage welding machine is a semi-automatic steel bar processing equipment specifically designed for construction, bridges, high-speed rail, and other projects. It is primarily used in the steel cage winding and molding process. Its core function is to evenly wrap the stirrup around the outer surface of the main skeleton using mechanical transmission and welding technology, thereby forming a stable steel cage. This equipment is especially suitable for producing round or spiral steel cages in pile foundation engineering, capable of meeting the requirements for a main reinforcement diameter of 650mm and a stirrup diameter of 512mm. It is widely used in areas such as bridge pile foundations, expressways, urban pipe corridors, and high-rise buildings.
Compared to traditional manual lashing, the CNC steel cage welding machine efficiency through semi-automated operations, producing 10 to 20 steel cages per day (depending on worker proficiency and equipment configuration), while also reducing labor costs and material waste.
1. Intelligent control and high-precision machining:
The numerical control (NC) system and imported servo motor drive support parametric settings and allow for adjustments to cage diameter, stirrup spacing, and bending angle, with error control within ±2mm.
It is also equipped with fault self-diagnosis and alarm functions to ensure operational stability and reduce downtime.
2. Flexible adaptation and diversified production:
It can design up to 60 types of corner shapes, support the customized production of steel cages in various specifications, and store thousands of graphic libraries to meet the batch requirements for multiple varieties.
It is compatible with a main rib diameter of 1250mm, and the stirrup spacing can be automatically adjusted to meet the special process requirements of the encryption and reservation areas.
3. Efficient production and energy saving:
The automatic feeding, straightening, and welding integration design reduces manual intervention. With just 3-6 people, the entire operation can be completed, achieving efficiency 3 to 4 times higher than manual methods.
No stirrup overlap is required, increasing the material utilization rate by 1% to 1.5%, and saving hundreds of meters of steel reinforcement loss in a single day.
4. Durable structure and safe operation:
The key components are made of high-strength alloy steel, which is resistant to wear and corrosion, thereby prolonging the life of the equipment.
It is equipped with leakage protection, an emergency stop device, and an automatic welding manipulator, all of which reduce the safety risks associated with manual welding.
1. Low cost and high return:
The equipment is affordable, making it suitable for small and medium-sized projects or private contractors, with a short return on investment.
The daily output is equivalent to that of 10 skilled workers, reducing labor costs by more than 50%, and lowering overall construction costs by 15% to 20%.
2. Stable quality, worry-free acceptance:
The mechanized production ensures that the main reinforcement is evenly distributed, the stirrup spacing is consistent, and the finished product has a 99% qualification rate, meeting national building codes.
With high solder joint strength and no leakage welding, the overall structural stability of the steel cage is improved, reducing project risks.
3. Convenient operation, strong adaptability:
Workers can begin work after just 30 minutes of training. The system supports touch screen operation and remote monitoring, reducing the technical threshold.
1. Economical and Practical
The initial investment is low, maintenance is straightforward, and it is ideal for short-term or small-scale projects. Its cost-performance ratio is significantly higher than fully automatic equipment.
2. Flexible Operation
Different stirrup shapes can be continuously produced without complex mechanical adjustments, and product specifications can be switched mid-process.
The multi-axis linkage design enables simultaneous processing of multiple steel cages, improving efficiency.
3. Quality Assurance
The processing causes minimal surface damage to the steel bars, which does not affect compressive strength, and the uniformity of the finished product is better than that achieved by manual binding.
With its intelligent control, flexible adaptability, and efficient production capacity, the CNC steel cage welding machine has become indispensable in modern infrastructure projects. Its high cost performance, stable quality, and low operating costs make it especially suitable for small and medium-sized projects, helping construction enterprises shorten the construction period and enhance their competitiveness.
