steel bar straightening machine for rebar recycling

In the metal recycling industry, scrap steel rebars ranging from 6-25mm in diameter and 500-2000mm in length are often discarded inefficiently due to bending and deformation.

Our fully automatic steel bar straightening machine can convert scrap steel into straight building materials with an accuracy of ≤1mm/m in just 30 seconds, utilizing a dynamic pressure sensing and cutting system. This process boosts the material utilization rate to over 95%.

The steel bar straightening machine’s strength and straightness comply with the new national standards, resulting in savings of more than 35% in reprocessing costs per ton of scrap steel, and offering “zero-waste” efficient recycling solutions for the construction, manufacturing, and other industries.

Advantages of steel bar straightening machine

1. Handle steel bars with diameters ranging from 6 to 25mm in just 30 seconds, ensuring a surface scratch rate of less than 3% and a straightness error of no more than 1mm per meter. The finished product is ready for high-standard welding applications.
2. Support for free settings between 500 and 2000mm, with a cutting accuracy of ± 2mm. The section flatness exceeds industry standards by 30%, making it ideal for precision processing needs such as bolts and connectors.
3. Featuring an innovative energy-saving transmission structure (motor + reducer), this steel bar straightening machine reduces energy consumption by 40% compared to traditional models, with operating noise levels below 70dB, meeting green production certification requirements.
4. The modular design occupies only 5 square meters, and the touch screen interface allows for one-key start and stop functionality, requiring no professional training for operation. It adapts well to various complex working conditions, including sites and workshops.
5. With a triple protection mechanism, the continuous operation failure rate is less than 0.5%, and the core components have a lifespan exceeding 8000 hours, ensuring safety during high-intensity production.

Range of steel wire straightening machine applications

1. The bent and rusted scraps from construction sites are transformed into straight bars, which are then used directly for tying or welding beams and columns. This process shortens the construction period by over 20% and cuts the procurement cost of new materials by 40%.
2. Deformed steel tailings generated from refurbished machine tool processing are utilized in making bolts, connectors, and other precision components, achieving a material utilization rate of 97% and reducing the area taken up by scrap accumulation by 50%.
3. In situations like road collapses and building damages, it can operate in the field with a mobile power supply, regenerating 12 tons of building materials in just 8 hours, and facilitating the quick erection of temporary bridges and reinforced structures.
4. This technology is applicable in bridge engineering, subway tube sheet prefabrication, agricultural greenhouse frameworks, and other scenarios, catering to the customized needs for guardrails, brackets, and more, while adapting to various standards such as ASTM/GB.

Waste steel bar correction machine working principle

The electric motor boosts the speed via a belt drive, causing the straightening cylinder to rotate rapidly. This process straightens the steel bar and removes any rust using the straightening mold.

Simultaneously, another set of deceleration belt drives and a gear reducer move the transmission pressure roller, pulling the steel bar forward and driving the crank wheel, which makes the hammer head move up and down.

Once the rebar reaches the specified length, the hammer strikes the upper knife frame to cut it, and the severed rebar falls into the feed frame. The knife table then resets with the help of a spring, completing one working cycle.
