Steel bar straightening machine is a highly efficient tool designed for recycling and processing discarded, bent, and waste steel bars. This steel bar straightening machine comes in a variety of models, mainly suitable for processing steel bars from 6 to 25 mm in diameter, ensuring smooth, precise straightening and cutting of used steel bars, making it suitable for reuse in construction projects and manufacturing.
The compact size of this scrap steel recycling machine makes it easy to maneuver in various working environments. In addition, the machine is easy to operate and usually requires only one worker to operate. Its processing efficiency is high, and it can process 30 meters to 35 meters of steel bar per minute.

Structure Of Steel Bar Straightening Machine
The steel bar straightening machine consists of a motor, a reducer, two sets of rollers, and a double-pressure adjusting bar.
The waste rebar straightening machine is driven by a powerful motor and gear reducer, which is quick to regulate, highly efficient, and reliable, ensuring smooth operation without jamming or causing damage. The surface of the straightened steel bar is smooth without obvious scratches and maintains good straightness, making it ideal for reprocessing.

Characteristics Of Steel Bar Straightening Machine
- High-speed Straightening: The machine quickly straightens steel bars to minimize defects and ensure that it is ready for further processing.
- Cutting Capability: Equipped with cutting blades, the machine can easily handle large angle bends and cut the bar to the desired length, providing flexibility in the straightening process.
- Efficient Operation: The straightening drum is driven by an electric motor and rotates at high speed, while the two conveyor rollers pull the steel bar forward. The crankshaft wheel drives the hammer head up and down to cut the bent profile.
