Reinforcing bars, forming the skeleton of concrete, constitute reinforced concrete and are the most widely used and abundant main material in building structures. Before pouring concrete, the reinforcing bars must be made into a skeleton of certain specifications and forms and incorporated into the formwork. Creating the reinforcing bar skeleton requires processing the bars through strengthening, stretching, straightening, cutting, bending, and connecting, before finally binding them into shape. Due to the enormous quantity of reinforcing bars used, manual operation is difficult, requiring various specialized machines for processing. These machines are called reinforcing bar processing machinery, or simply reinforcing bar machinery.
Reinforcing bar processing machinery is construction engineering equipment used to process coiled and straight reinforcing bars into the required lengths, shapes, or components for concrete structures. It covers processes such as strengthening, straightening, bending, cutting, bending, and splicing, and is mainly divided into five categories: reinforcing bar strengthening machinery, reinforcing bar forming machinery, reinforcing bar welding machinery, reinforcing bar splicing equipment, and reinforcing bar prestressing machinery. Its functions include increasing the strength of reinforcing bars through processes such as cold drawing and cold stretching; forming reinforcing cages, reinforcing trusses (such as triangular beams, wall panels, columns, etc.), and reinforcing meshes using equipment such as straightening and cutting machines and bending machines; and completing the connection and prestressing treatment using welding machines and stretching machines.
In recent years, reinforcing bar processing machinery has achieved intelligent control of equipment such as reinforcing bar cutting production lines, bending production lines, and mesh welding production lines by applying servo motor control technology, PLC/PCC computer control technology, and industrial-grade touch screen human-machine interface technology, thereby improving processing efficiency and quality.
