2. Main euqipments for Metal Copper Air Conditioner Pipe/ Air conditioning duct Production Line

1.    Three-roll planetary mill ,Model:FXZJ-SG

Product description of three - roll planetary rolling mill

Technics Characteristic

1)     High pressure down rolling mill, single channel extension coefficient can reach more than 16

2)     Rolling deformation is reasonable, after rolling the state was homogeneous recrystallization equiaxed grains

3)     Solar terms effect is perfect

4)     Using horizontal continuous casting hollow tube billet, the outer diameter of the tube can reach φ120mm

5)     High degree of automation and high production efficiency

2. Whirlwind milling machine

Technics Characteristic

1)    A milling that completes the surface of the circular surface 0.3 ~ 0.5mm at one time feeding.

2)    A milling that completes the surface of the circular surface 0.3 ~ 0.5mm in one feed.

3)    Copper tube billet length in the 2 ~ 15m or even longer can be used

4)    The billet feed can be adjusted at infinity

5)    Three - blade adjustable milling surface

Technical parameter

Processing copper tube billet outer diameter: φ60 ~ φ120mm

Thickness of copper billet pipe: ≥ 8mm

Copper billet tube length: 10~30m

The thickness of the flaying circumference: 0.5±0.2mm

Speed: 0~2m/min

3. Crawler-type continuous drawing machine or CAM type combine drawing machine

Technics Characteristic

The FXLS series combined drawing machine is used to reduce the diameter and wall thickness of the mill and pilger mill. The pipe is hardened during drawing. This pull can reduce the pull - pull of the puller. Because of the hardness of the tube drawing, the tube can be drawn at high speed through a disc drawing machine.

Technical parameter 

1)    Maximum drawing force: 1st drawing 100kN, 2nd drawing 80kN, 3rd drawing 60kN.

2)    Maximum drawing speed: 120m/min (3rd drawing)

3)    Feed specifications: (φ43~φ50mm)X(2.0~2.5mm)

4)    Equipment drive system: DC motor, Full digital controllable DC converting controlling system.

5)    Total power: 450Kw

6)    Total weight of equipment: 82 Tons
