The Return Bender machine is designed to open, straighten, cut, and bend coil copper tubes into return bends. It is primarily used in the manufacturing of air conditioning condensers, evaporators, water heaters, and other heat exchange systems. This fully automatic machine significantly enhances production efficiency and precision.
1. The Return Bender is a crucial component in the production of return bends. It connects the two legs of a hairpin tube through a brazing process, which is essential for fabricating heat exchange coils. Depending on the tubing size, the machine can produce 2–5 pieces per cycle, with an efficiency of 10–14 cycles per minute.
2. Key features of the Return Bender:
- 2.1 The machine operates in full automatic mode. Once the coil tube is loaded, it automatically performs the following sequence: feeding, clamping, mandrel insertion, spraying, bending, pulling the mandrel, cutting, unloading, and repositioning for the next bend.
- 2.2 It includes a motor-driven stock stand, similar to that found in tube cutoff machines, ensuring smooth and consistent operation.
3. Main Electrical Components:
- 3.1 The control system is equipped with a Japan OMRON PLC for reliable and precise operation.
- 3.2 Pneumatic components are sourced from SMC, known for their durability and performance.
- 3.3 Hydraulic parts are provided by Yuken, a well-known Japanese brand, ensuring high-quality hydraulic functionality.
