The full automatic fin evaporator serpentine tube bender delivers complete in-line bending automation for mass production of aluminum tubes used in HVAC heat exchangers and air conditioning evaporator coils. It integrates the entire end-to-end process from decoiling, straightening, cutting, bending, and recoiling finished serpentine tubing with minimal manual intervention.

 

The machine maximizes productivity by simultaneously processing up to 10 aluminum tube groups with its unique multi-tube bending approach. The proprietary bend sequencing strategy and precision servo-electric actuators shape the tubes into intricate serpentine coils required for finned evaporator assemblies.

 

Advanced positional algorithms help optimize the collision-free rotation and manipulation of multiple tube groups through the bend stages. Customized groove tooling enables bend radii down to R11 mm without tube damage, while specialized blade shapes allow fast chipless cutting.

 

The sturdy modular steel frame construction with machined precision axes and hardened transmission gears ensures reliability in high-duty cycle operations. The centralized PLC software seamlessly coordinates the various automation modules.

 

Overall, this high-performance evaporator tube bending solution provides manufacturers with the automation technology essential for cost-effective high-volume production.

1.Bulk Tube Decoiling & Feeding

The automated decoiler continually uncoils aluminum tube stock and feeds it to the first set of tube straightening rolls for initial straightening.

 

2.First Stage Tube Straightening

The first set of powered tube straightener rolls removes the bulk of the coil curvature from the aluminum tubes before initial draw feeding.

 

3.First Stage Tube Feed System

This initial servo-powered feed system draws the partially straightened tube from the decoiler and feeds it through the second set of straighter rolls.

 

4.Precision Tube Cutting Unit

The pneumatic shear cutting unit makes highly precise cuts at right angles without burrs or chips for superior weld seam quality.

 

5.Second Stage Servo Feeder

The secondary servo feed system accurately positions and feeds measured tube lengths for the bending sequence by the servo manipulator.

 

6.Robotic Servo Tube Manipulator

This 6-axis articulating robotic arm picks, orients, and accurately positions up to 10 tube groups concurrently for synchronous synchronized bending.

 

7.Custom Serpentine Tube Bending Section

The programmable bend head makes sequential G and U bends with extreme precision through 360-degree rotation to create the desired serpentine coils.

 

8.Automated Tube Recoiler

Finished bent aluminum tube batches are automatically collected and recoiled by the outfeed system for the next production stage.

 

9.Centralized Industrial Control System

The centralized PLC automates the sequencing and motions using integrated software, while the touchscreen HMI facilitates intuitive operator control.

 

The highly coordinated automation modules work in unison to deliver high-speed, high-accuracy aluminum tube bending for evaporator manufacturing.
