High Quality Semi-automatic Hairpin Tube Bending Machine
1.Application
The hairpin bender machine is one of the necessary equipment of HVAC
production line. We have full range HVAC equipment such as high speed
fin press, progressive fin die, servo type tube expanding machine, semi
automatic and fully automatic hairpin bender, etc. This semi automatic
hairpin bending machine has the functions of manual feeding, servo
positioning, servo bending, and servo unloading. The hairpin length
ranges 200-3000mm. The tube diameter ranges from 7mm-16mm.
The production efficiency can be 2-5pcs per cycle.
2.Technical Parameters:
| Tubing Diameter | O.D. 9.52/12.7mm |
| Hairpin length | 200-3000mm |
| Working efficiency | 9.52 *2 + 12.7 * 2 tubes/cycle |
| Normal voltage | 380V, 3P,50Hz |
2.1 Structure Characters:
2.1.1 Compact design, Servo motor driving, Manual feeding, Operation in
manual or automatic mode For o
ption
2.1.2 Process of automatic operation mode is material feeding by manual
→mould tooling clamping→ oil spraying → bending → mandrel back →
clamp loose → unloading → unloading home → bending tooling home
2.2 Hairpin Leg difference in length less than 0.5mm
2.3 No obvious clashing, abnormal “bump”, corrugation neither other
deficiency. Ellipse less than 8%
2.4 Roundness tolerance of bend area <±.012”;
2.5 Parallel tolerance for the two straight legs ≤3%;
2.6 Running and operating smoothly.
3.Performance parameters of machine:
