The hairpin bender is used to open, straighten, cut and bend copper coils into U shapes, or hairpin pipes. These machines are mainly used for the automatic production of U pipes installed in AC condensers and evaporators.
- Automatic hairpin bender
- Quick change over between two tube diameters
- Automatic conveying tube - collector
- Multi-center distance
- Copper black spot detection
Features:
1. The stripper and frame move and bend by servo motor.
2. Driven by frequency conversion motor and fed by belts.
3. Cutter motor is driven by transducer, and the speed
can be adjusted.
