Auto Serpentine Tube Bending machine


 
Description of auto serpentie tube bending machine:
This machine is specially for bending multiport flat aluminum tubes to be serpentine shape for condenser and evaporator purpose.
This machine is comprised of coil tube pay-off stand, straightening device, auto feeding device, auto bending head, stretch cutting device.
This machine is PLC control, HMI operation. Feeding length, bending radius and bend quantity can be preset on the touch screen and the program can be saved for future use.
By using servo motor feeding and ball screw transmitting, repositioning accuracy is very high.
