The Return Bender machine is designed to open, straighten, cut, and bend coil copper pipes into return bends. It is primarily used in the manufacturing of air conditioner condensers and evaporators, water heaters, and other heat exchange systems. The machine operates in full automatic mode, ensuring high efficiency and precision.
1. The Return Bender is a crucial component in the production of return bends. It connects two legs of a hairpin bender through a brazing process, which is essential for fabricating heat exchange coils. Depending on the tubing size, the machine can produce 5 or 3 pieces per cycle.
2. Key features of the Return Bender:
- 2.1 The machine is fully automated, performing the following sequence automatically: Feeding → Clamping → Mandrel Insertion → Spraying → Bending → Pulling the Mandrel → Cutting → Unloading → Repositioning for the next bend.
- 2.2 The stock stand is motor-driven, similar to that of a tube Cutting Machine, ensuring smooth and consistent operation.
3. Main electrical components include:
- 3.1 Control system: Japan OMRON PLC
- 3.2 Pneumatic parts: SMC
- 3.3 Hydraulic parts: Japan Brand Yuken
