The rebar straightener machine is a core automatic steel bar processing equipment widely used in construction and steel fabrication industries. It is professionally designed to straighten deformed coiled steel wires, round rebars, and twisted rebars, and cut them into customized fixed lengths automatically. Traditional manual straightening and cutting methods are time-consuming, low-precision, and labor-intensive, easily causing material waste and size errors. This intelligent rebar straightener machine adopts high-speed roller straightening technology and a computer numerical control system. It can automatically complete feeding, straightening, length setting, fixed-size cutting, and material discharging in one continuous process. Featuring high precision, stable operation, and simple maintenance, it greatly saves labor costs, reduces steel waste, and improves overall construction efficiency for all kinds of building foundation and steel processing projects.

7 Working Process of YG Rebar Straightener Machine
- Pre-Operation Inspection and Parameter Setting: Before starting work, operators need to conduct a simple equipment inspection. Check the tightness of straightening rollers, blade sharpness, motor operation status, and lubrication of transmission parts to avoid jamming or cutting errors. According to construction drawing requirements, workers input the required steel bar length and cutting quantity through the digital control panel. The intelligent system will automatically record and lock the parameters to ensure unified size standards for all processed rebars.
- Automatic Feeding and Conveying: After parameter confirmation, place the coiled rebar or steel wire on the material rack. The machine’s dual-power traction rollers will automatically clamp and drag the steel bar forward steadily. The traction speed is uniform and adjustable, which effectively avoids shaking, deviation, and surface scratches during feeding. This automatic feeding design completely replaces manual material pushing, greatly improving feeding stability and speed.
- Multi-Roller High-Precision Straightening: This is the core step of the rebar straightener machine. The equipment is equipped with multiple groups of upper and lower staggered straightening rollers. When the bent steel wire passes through the roller group, the uneven bending and torsion deformation are continuously squeezed and corrected in multiple directions. The repeated physical calibration eliminates all arc deformation, torsion, and irregular bends. After straightening, the steel bar surface is smooth and flat with zero bending error, fully meeting international construction steel standards.
- Fixed-Length Intelligent Positioning: The high-precision sensor installed at the discharging end monitors the real-time feeding length of the steel bar. Once the steel bar reaches the preset cutting size, the system instantly locks the feeding structure to stop material delivery accurately. This intelligent positioning technology avoids manual measuring errors, ensuring every finished steel bar has the same length.
- Automatic Hydraulic Cutting: After positioning is completed, the hydraulic cutting system instantly drives the high-hardness alloy blade to complete fast cutting. The cutting process is stable, with a flat incision, no burrs, no steel bar deformation, and no cracking. Compared with traditional manual cutting and ordinary mechanical cutting, hydraulic cutting has higher toughness and can process high-strength steel bars without blade damage.
- Automatic Discharging and Cycle Operation: After cutting is finished, the finished steel bar automatically falls to the material receiving rack. The machine immediately resumes feeding and straightening work to start the next working cycle. The whole cycle runs continuously and efficiently, realizing batch and large-volume steel bar processing without repeated debugging.
- Post-Work Cleaning and Maintenance: After daily construction, clean the iron scraps on the straightening rollers and cutting blade, check the lubricating oil level, and turn off the power. Simple daily maintenance can effectively extend the service life of the wire straightening and cutting machine and ensure stable long-term operation.
6 Wide Application Scenarios of Rebar Straightening and Cutting Machine
1. Building Foundation Construction Projects
It is the most widely used in residential buildings, commercial buildings, office buildings and villa foundation engineering.
