Working Principle & Structural Features
1. Full-Process Automatic Workflow
The machine adopts a fully automatic closed-loop control system: coiled steel bar → automatic feeding → high-precision straightening (straightness ≤±1.5mm/m) → servo traction sizing → CNC bending forming → automatic cutting → finished product output. The entire process requires only one operator for parameter setting and monitoring, realizing unmanned continuous production.
2. Key Structural Components
Straightening Mechanism: Double groups of horizontal and vertical adjustable straightening wheels, driven by servo motors, ensuring steel bar straightness and reducing internal stress.
Bending System: Equipped with 1–5 independent bending heads (synchronous or sequential operation), hydraulic/servo drive, strong bending force, fast response, suitable for complex stirrup shapes.
Control Console: High-definition touch screen with graphical interface, built-in standard shape library, supporting custom programming, one-key switching of production specifications.
Cutting Mechanism: Hydraulic shearing, clean cut, no burrs, matching bending speed to ensure production continuity.
