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.
Principais vantagens
1. Ultra-High Efficiency & Labor Saving
One machine can replace 10–30 skilled workers, with daily output exceeding 15 toneladas (about 8,000–12,000 stirrups), 8–10 times that of manual work. It supports 24-hour continuous operation, greatly shortening the construction period.
2. Precision & Consistency
Length error controlled within ±1mm, angle error within ±1°, ensuring each stirrup meets design specifications, completely eliminating manual operation errors.
3. Wide Adaptability & Flexibilidade
Compatible with round steel and deformed steel bars of 6–18mm, capable of producing rectangular, square, diamond, polygonal, and other special-shaped stirrups, meeting diversified processing needs of housing, pontes, túneis, ferrovias de alta velocidade, etc..
4. Inteligente & Operação fácil
10.5-inch touch screen, built-in 500+ standard graphics, new operators can master operation in 30 minutos; supports fault self-diagnosis and alarm, convenient for maintenance.
5. Energy Saving & Economia de materiais
Intelligent cutting algorithm reduces head and tail material waste, improving material utilization by 5%–8%; servo drive reduces energy consumption compared with traditional hydraulic models.
6. Sturdy & Durável
Thick steel plate welded body, core components quenched, service life up to 8–10 years, adapting to harsh construction site environments.
Application Scenarios
Construction Engineering: High-rise buildings, commercial complexes, residential quarters (beam and column stirrup processing).
Infrastructure: High-speed railways, rodovias, pontes, túneis, airports, projetos de conservação de água.
