This equipment is a core processing unit in the AAC (autoclaved aerated concrete) panel production line. It integrates straightening, cutting, and rust removal into a single automated process, converting coiled or bent rebar into straight, clean, and accurately cut longitudinal bars ready for mesh welding. A multi-stage composite straightening mechanism ensures excellent linearity and relieves internal stress, while the cutting system achieves a length tolerance within ±5 mm. The built-in CNC controller allows automatic length setting and cutting, accommodating various rebar diameters with simple parameter adjustments. By delivering high‑precision straightened rebar, this machine enhances production efficiency and guarantees the structural integrity of AAC panels, making it an indispensable asset in modern lightweight wall panel manufacturing.
