High quality servo motor CNC automatic straight bar stirrup bending machine for pulic work
Product Overview
This machine handles the full sequence-feeding, straightening, bending, and cutting-without manual intervention. It maintains a steady output of around 1,600 stirrups per hour and processes up to 8 tons per batch, even during extended shifts.

Key Performance Features
●Structural Stability: The reinforced frame and 42 KW power system support continuous operation. In our experience, the heavier build reduces vibration during bending.
●Dual-Wire Processing: Switching between single-wire and dual-wire modes doesn't require tool changes. This flexibility is useful when orders shift between finer stirrups and heavier reinforcement bars.
●Precision Control: Using Delta PLC and EURA servo motors, the machine holds length tolerance within ±1mm and angle tolerance within ±1°.
Product Details
Pre-Alignment System:
Sixteen alloy steel wheels, divided into upper and lower groups, are each servo-controlled. This setup allows fine-tuning without stopping production, and the dual-groove design supports simultaneous two-wire feeding.
Straightening Mechanism:
Eighteen flat-grooved wheels handle both rebar and round steel. The independent servo control on upper and lower groups means operators can compensate for material variation without manual resetting.
Practical Features:
A 75–100m/min traction speed keeps pace with most production schedules. The HMI supports multiple languages, which helps when training new operators or supplying machines to different regions.
Ideal Applications
We commonly see this CNC automatic straight bar stirrup bending machine in precast concrete plants and infrastructure fabrication yards. It's also well-suited for bridge and tunnel steel cage preparation, where large volumes of uniform stirrups are required daily.
