Working Principle
The Hydraulic Rebar Spiral Bender operates by utilizing a mechanical and control system to pre-set bending angles and arcs, allowing for automated bending. Key components include:
- Driving and Passive Wheels: Steel bars are positioned at the feed port, with the distance between wheels adjusted based on bar size. The active wheel feeds the steel bar into the machine, allowing quick and precise bending.
- Multiple Bending Molds: Equipped with interchangeable molds, the machine can accommodate various diameters and shapes to meet different bending requirements.
- Control System: Ensures precise control over bending angles and speeds for accurate results.
Applications
The Hydraulic Rebar Spiral Bender is crucial in several industries, including:
- Construction of Infrastructure: Ideal for bending steel bars into specific circular or spiral shapes required for buildings, bridges, and tunnels.
- Bridge Construction: Bends steel bars into complex shapes to fit precise structural requirements in bridge frameworks.
Operation and Maintenance Guide
Mechanical Checks
Before use, ensure the machine’s mechanical components are in good condition, and that the workbench is level.
Mold Installation
- Set up the mandrel, forming shaft, or variable stop frame based on the diameter of the steel bar being bent. The mandrel diameter should be 2.5 times the bar diameter for optimal bending.
Safety Inspection
- Inspect the mandrel, stopper, and turntable for any damage or cracks. Ensure that the protective cover is securely fastened.
Operation Specifications
- Insert the steel bar into the turntable gap, securing one end against the machine body. Avoid adjusting the mandrel or speed settings during operation.
Run Empty First
- Run the machine without material to ensure normal operation before starting actual bending.
By adhering to these operational and maintenance procedures, the Hydraulic Rebar Spiral Bender guarantees efficient, safe, and precise bending of steel bars for a variety of applications in construction.
