The five-head steel bar bending center is a high-end model in the field of automated steel bar processing equipment. Its core feature lies in being equipped with five independent bending heads, enabling continuous processing that integrates simultaneous feeding, bending, and cutting of five steel bars.
In the industrial chain of building industrialization, the five-head steel bar bending center is positioned as the core equipment for large-scale steel bar processing scenarios. It connects upstream with steel bar raw material suppliers and serves downstream projects with high steel bar demand, such as large-scale residential construction clusters, prefabricated building production bases, and high-speed rail hubs. Compared with the dual-head model, its processing efficiency increases by 80% to 120%. It is one of the key pieces of equipment enabling the construction industry to achieve cost reduction, efficiency improvement, and standardized production.
Core Structure of the Equipment
Multi-Head Collaborative System
Five bending heads are arranged in a straight line, each equipped with an independent servo drive unit and bending die. The bending angle (0°–180°) and bending radius (50 mm–300 mm) can be set independently through the numerical control system. It supports two operating modes: simultaneous processing of five steel bars of the same specification or group processing of two to three steel bars of different specifications, meeting diverse production demands. The spacing between machine heads can be adjusted according to the length of the reinforcing bars to accommodate various component lengths.
Synchronous Feeding Mechanism
The system adopts five sets of independent servo motors combined with ball screw transmissions. Each feeding mechanism corresponds to one bending head, with feeding accuracy reaching ±0.3 mm. Through the numerical control system's synchronous control algorithm, the feeding speed (0.5–1.2 m/s) and feeding length of the five reinforcing bars remain perfectly synchronized, avoiding errors caused by feeding deviations. The feeding rack adopts a layered design divided into five independent material troughs, allowing pre-stacking of steel bars of different specifications to reduce loading wait time.
Breakthroughs in Key Technologies
Multi-Axis Cooperative Control Technology
Adopting an industry-based multi-axis synchronous control scheme, the numerical control system coordinates five bending heads and five feeding mechanisms in real time, with a control delay of ≤0.1 s, ensuring seamless integration of the feeding–bending process.
Intelligent Programming and Parameter Storage
The system supports automatic import of CAD drawings and can automatically identify the dimensional parameters (length, angle, number of hooks) of steel bar components to generate processing codes, eliminating manual parameter input. It is equipped with a built-in library of over 2,000 common steel bar component models, covering special parts such as stirrups in prefabricated building composite slabs, steel bars in high-speed railway tracks, and support bars in utility tunnels. Operators can select models and fine-tune parameters through the touch screen. The system simultaneously supports the storage of 1,000 sets of processing parameters, enabling parameter reuse across multiple projects.
