Production Line
Chipless Return Tube Bending and Ring Loading Line
Product Application
This device is used for unwinding, straightening, chip free cutting, and bending disc-shaped copper pipes into small U-tubes; After being dried by the drying line, the small U-tube enters the vibration disc, and the ring part is fitted with welding rings at both ends of the small U-tube. Mainly used for the fully automatic production of welding ring small U-tubes for air conditioning units.
This equipment is designed for fully automatic production of welding ring small U-tubes for air conditioning units, suitable for large-scale production, which can improve efficiency, ensure product quality, and reduce manual intervention.
product Features
1. Dust-free cutting technology: The equipment adopts copper pipe chip-free cutting technology, which helps to reduce material waste and improve production efficiency.
2. Bending and integer function: chip-free small U set ring all-in-one machine can realize the bending and integer of the small U elbow, making the product more in line with the production requirements.
3. Double station automatic production: integrates the process of the set ring, double station automatic production, simplifies the production process, can realize unmanned operation, so as to reduce the labor cost and improve the production efficiency.
4. With defective products: automatically detect U ring, eliminate residual products, improve the yield.
