The GWH32E steel bar arc bending machine is special forming equipment for infrastructure projects. It is widely used for processing tunnel supports, bridge arches, culverts, steel structures, photovoltaic brackets and curved components of large buildings. It rolls straight deformed bars and round bars into circular arcs, semicircles, spiral stirrups and ring steel bars, making up for the limitation of ordinary benders which can only form sharp angles instead of curved shapes.
This machine processes standard deformed bars and plain round bars from Φ6 mm to Φ32 mm. It adopts a three-roller forming structure with stable power transmission and smooth rolling. The finished arc is sleek without extrusion scratches, and the mechanical properties of steel bars remain intact. Equipped with manual and automatic dual control modes, the control panel is user-friendly. Operators can adjust bending radius freely to fabricate curved workpieces with different curvatures to meet various drawing requirements. Transmission gears are quenched and tempered to withstand heavy loads for long continuous operation.
The machine frame is integrally welded with thickened steel profiles to guarantee high rigidity and reduce vibration during operation. Fitted with mobile casters at the bottom, it can be moved flexibly on construction sites without heavy lifting equipment. The core pressing rollers are made of wear-resistant alloy steel with strong anti-extrusion performance, ensuring stable dimensional accuracy in mass production. Different from traditional flame heating bending, mechanical cold bending requires no heating, which is eco-friendly. It delivers consistent finished sizes, lowers rework rate and cuts labor and material waste.
Start-stop buttons and an emergency stop device are equipped together with overload protection. The machine can be protected in case of bar jamming or overload to improve site safety. Easy to operate, one worker can complete feeding, radius adjustment, arc rolling and unloading. Universal wearing parts simplify daily lubrication and maintenance and reduce long-term operation costs.
With growing demand for tunnel arch bars, pile foundation spiral stirrups and curved beams, the GWH32E steel bar arc bending machine stands out for excellent forming quality, flexible adjustment, convenient mobility and stable performance. It serves as core equipment for standardized curved steel processing and is a necessary machine for steel processing factories, bridge and tunnel construction projects.
