Hydraulic bending machine YG series

servo-electricconcrete reinforcementfor steel bar

Overview
YG Machinery CNC Stirrup Bending Machine is an automated rebar/stirrup processing system that converts coiled rebar into a wide range of stirrup shapes. It combines servo-driven bending, digital straightening, hydraulic cutting and an industrial CNC controller to deliver precise, high-speed production for construction and precast factories.

Core product features and working principle

• Cage-style rotating straightening mechanism with digital metering, hydraulic cutting and a multi-head hydraulic bending assembly driven by a servo control core.
• Precise straightening: adjustable horizontal and vertical straightening wheels plus servo traction wheels ensure high-precision straightening of coiled rebar.
• Efficient bending and cutting: independent servo motor for the bending arm enables rapid rotation and retraction; sliding cutter reduces wear and suits small stirrup production.
• Intelligent control and storage: industrial CNC touch-screen controller stores up to 60 bend angles and multiple templates (square, rectangular, circular, polygonal stirrups).
• Built-in diagnostic functions monitor component wear and assist maintenance planning.

Applications

• High-rise building projects: mass production of standard and custom stirrups for beams and columns.
• Infrastructure works: highways, rail and tunnel projects requiring high bending accuracy for rebar components.
• Precast concrete factories: batch production of rebar cages for precast elements.
• Heavy steel structure workshops: compatible with processes that require precise servo control for section-related tasks.

Key advantages

• Increased throughput: replaces multiple skilled workers; single-operator handling reduces labor needs.
• High precision: servo control yields consistent length and angle accuracy for continuous production.
• Easy maintenance: closed-structure design, gear splash lubrication and diagnostic features simplify upkeep.
• Material versatility: supports cold-rolled and hot-rolled rebar across common construction grades.
