Machine Work Principle
-
Rebar Loading: The operator inserts the main reinforcement bars into precision-aligned holes on both fixed and rotating disks.
-
Spiral Welding: Coiled wrap reinforcement is automatically welded to the main rebars while the disks rotate, creating perfect spiral formation.
-
Quality Assurance: The PLC-controlled system maintains:
-
Exact stirrup spacing (±2mm tolerance)
-
Consistent cage diameter throughout production
-
Continuous weld quality meeting ISO 1461/BS 4449 standards
-
-
Autonomous Operation: The closed-loop system requires only initial setup, then runs uninterrupted with real-time monitoring.
