Bfo-3000 Oval Duct Fabrication Machine

Introduction:

• BYFOCNCoval duct machine is a spiral duct roll formed by a spiral duct machine and then expanded to a standard oval duct with an oval duct machine.
• The oval duct machine is used for manufacturing the oval ducts. The oval duct machine can expand the spiral duct to the standard size of the oval air duct as customer’s requirement.
• With the advantages of good rollforming, high efficiency, easy operation, etc., It is indispensable equipment in the production of HVAC ducts.
• In addition to the advantages of a beautiful appearance, The oval duct also has higher strength, better air tightness, and greatly reduces the installation space of the HVAC air It expands the application of the oval duct. The oval duct is also an ideal alternative to the rectangular duct.
• Ovalair duct machine has the characteristics of good shape, high efficiency, and easy operation.
• An oval duct machine is a necessary machine in making HVAC duct industry. The oval duct machine is controlled by a PLC controller and the LCD panel stores all the set parameters, the operator can easily operate the machine.
• Since the oval duct machine was put on the market, the application of oval duct machines in ventilation and air conditioning systems has been promoted continuously. Most of the oval ducts are also widely used in shipbuilding ventilation, purification, textile exhibition, and other ventilation and dust removal fields

I: Oval duct machine’s advantages:

• Automatic mechanized rollforming, roll-formed oval duct clean without dust.
• The air leakage rate of the oval air duct is extremely low, only 0.02% and the cost of installing auxiliary materials is reduced by 30%.
• The oval duct machines can make 3000mm in length, the oval duct has the same size and is easy to install.
• The corrugation of the oval duct makes it has high strength and good rigidity and avoids secondary noise. The oval duct is a better choice than the rectangular duct because the ventilation quality is greatly improved.
• Roll-formed oval duct occupies a small space height and adapts to the height of insufficient buildings. It is more economical and space savings.
• The oval duct’s strength and gas density are better than the round duct. Its inner seam is smooth, which greatly improves the rigidity of the air oval pipe and also reduces the chatter noise.
• The advanced controls the programming and guarantees the accuracy of the oval duct. It promotes quick installation and convenient construction, which improves work efficiency and economic benefits.

II: Oval duct machine’s technical parameters

• Applicable material: Galvanized steel is 0.4mm-1.2mm
• The maximum oval duct length can be expanded to 3100mm

• Oval duct mold size can be chosen in the range: 150φ， 200φ，250φ，300φ， 350φ， 400φ， 450φ， 500φ。

We will send a free mold to customers and also oval duct machine can be customized above 500mm mold.

• Supporting rack size can be selected in the range：100， 200， 300， 400， 500， 600(mm)

If customers need a larger size of oval duct, The supporting rack can be combined using.

• Ovalduct’s making size: Height:150-500mm,Width:520-2300mm

• The range of round duct making size: 400mm-1500mm
• Oval duct machine’s motor power: 5 KW
• Max working pressure：20Mpa
• Oval duct machine’sdimensions: 5300mm×1600mm×1200mm

III: Oval duct machine’s function

• Spiral duct machine rollforms the round duct
• oval duct machine expands the round duct by analyse and input the size and then making oval duct.

III: Some main parts of oval duct machine

• Mold

Oval duct machine include one free mold，if you want more sets, must be charged additionally.

Mold size: 150φ， 200φ，250φ，300φ， 350φ， 400φ， 450φ， 500φ。

Larger size also can be customized.

• Expanding trays one set ( from 50mm to 600m)

Different size expanding trays can be combined with each other.

l PLC Control panel

Oval duct machine’s PLC control panel has all the technical parameters, it can easily help the operators set the parameters.

l Inner Structure

We upgraded inner structure spare parts and make it more stable for long time use.

• The hydraulic oil cylinder

We use multi cylinders on beam. it is better to expand round duct to oval ducts.

Also the oil cylinder has 26 sets. It made oval duct’s rollforming More uniform force, high synchronization.
