HVAC Automatic folding line

Automatic Folding Duct Line АFDL 516

Automatic Folding Duct Line performs entire cycle of a rectangular duct (straight sections) - leveling, grooving, cutting corners under the flange, cutting, forming Pittsburgh lock, TDF flange forming and bending. After the autoline duct should be closed with pittsburgh seam closer machine and TDF corners must be fixed to the flange spots. With automatic line production process duct becomes economical, fast and precise. Production of large amounts of high-quality products can increase sales on the market in a short time.
The line consists of a motorized double metal sheet decoiler (usually its two or four reels to feed different thickness raw material for different duct diameters), feeding system with servo drive motor, leveling unit, grooving rollers - to form stiffener ribs on the duct surface, hydraulic shearing, Pittsburgh lock-former, 4 side notching units, conveyor table, two side TDF flange former, hydraulic folding and CNC control panel.
The line is automatically controlled by CNC system with high-precision servo motors with feedback that allows you to achieve high accuracy, performance and reliability of the line.
The maximum operating speed of the line ~ 33 feet / min. Deviation ± 0.016" in length. Deviation ± 0.03" diagonal.
Two control modes - automatic and semi-automatic.
