Electric bending machine YG-RB series

hydraulicconcrete reinforcementfor steel bar

Product overview
A round bar bending machine by YG Machinery is industrial equipment for bending round steel and deformed reinforcement bars. Driven by electric motors or hydraulic systems, it forms preset angles (up to ±180°) for fast, repeatable rebar and round-bar processing used in construction, prefabrication and infrastructure projects.

Core performance advantages

• High efficiency: typical cycle 3–6 seconds per stirrup/set, reducing manual labour and cycle time.
• High precision: batch repeatability with length accuracy around ±1 mm and angle error ≤ ±1° (model-dependent).
• Integrated functions: some models combine straightening and cutting for complete rebar processing lines.
• Wide power range: available from ~3 kW for portable/site machines up to 20 kW for heavy-duty or CNC factory models.

Wide application scenarios

• Construction engineering: slab and column reinforcement, distribution bars and stirrups for residential and commercial sites.
• Bridge and tunnel projects: capable of high-precision bends and handling large diameters (examples up to 50 mm).
• Prefabricated component factories: programmable automatic models for continuous batch runs and reduced scrap rates.
• Road and railway infrastructure: heavy-duty variants for prolonged, high-load operation on large-diameter round steel.

Key selection considerations

• Power type — electric models suit workshops and small sites for faster cycles; hydraulic models provide higher torque for large-diameter bars.
• Bending capacity — select a machine whose maximum round-bar diameter matches or exceeds typical project sizes to avoid overload.
• Automation level — choose manual, semi-automatic or fully automatic (programmable) depending on daily throughput and labour availability.
• Portability & construction — lightweight portable units for site mobility versus full-steel stationary bodies for continuous factory use.
