Copper Tube Straightening Flaring & Cutting Machine

This is a standard coil copper tube straightening & chipless cutting machine, integrated with online flaring (expanding) function, full automatic, perfect for air conditioner copper tubing works.

I Main features:

- Servo feeding, stable and high re-positioning precision

- One time processing four pieces, high efficient

- Adopting pull-apart technology, less tube end ID reduction ratio

- Pneumatic flaring (expanding)

- PLC control, high automation—auto feed, auto flaring, auto cut, auto unload, auto alarm.

III Main buildup:

3.1 Pay-off device: four, passive decoiling

3.2 Straightening & rounding device: straightening deformation can be adjusted for different hardness copper tubes. When size changing, rounding wheel and straightening wheel will be changed.

3.3 Feeding device: driven by servo motor; Pulling and clamping dies are driven by enhanced pneumatic cylinders.

3.4 Cutting device: orbital-notching + pulling-apart method, pneumatic driving feeding stroke of orbital blade, stable feeding and quick returning; The feeding stroke can be fine adjusted to assure same mouth shrinking rate; Equipped with lubricant spraying device for lengthening blade life.

3.5 Flaring device: pneumatic elevating

3.6 Unloading table: covered with stainless steel, 700mm long

3.7 All the clamping dies are made by chrome steel, quenched HRC 50

3.8 Control system: PLC + touch screen

** Heavy-duty integrated flaring & cutting machine:

For bigger diameter copper tubes max. 22mm, above pneumatic flaring machine is not capable, but only hydraulic machine will be capable:
