Wondery BWJ-3000 ເຄື່ອງຕັດທໍ່ Hairpin ເຄິ່ງອັດຕະໂນມັດທີ່ມີຄຸນນະພາບສູງ (O.D: 9.52/12.7mm; 200-3000mm)

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.

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 option

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:

3.1. Working efficiency: 12 seconds per cycle taking 1 meter as example.

Pneumatic air consumption 3.5 cfm

3.2. Air cooled

4.Lubrication system

Expanding rod with lubrication holes and control by solenoid valve which allow oil spray every setting seconds (Injection time can be adjusted)
