HVAC duct fabrication machine Ⅲ features in high auomation,high efficiency and saving materials,which is very suitable for mass production of square ducts. Autoline - III consists of a metal feeding frame, leveling and grooving equipment, hydraulic punching square notch equipment, hydraulic cutter and folder. The electrical control system uses a computer with a closed-loop and servo-system to increase the precision and reliability of the manufacture line. The maximum working speed is 16m/min.The length tolerance is±0.3mm. The diagonal line tolerance is ±0.5mm. One team will produce 1000㎡of square duct by using this system.
Product detail:Features:Line Ⅲ consists of coiler frame, leveling and grooving device, hydraulic notching and punching device, hydraulic shearer and hydraulic folder. The electrical control part is mastered by computer and this control system is equipped with closed-loop feedback system, so it helps improve manufacturing precision and stability. The maximum feeding speed is 15m/min. The length tolerance is ±0.5mm and the diagonal tolerance is ±0.8mm. It features in high automation, high efficiency and saving materials. So it is very suitable for mass production of square ducts. Line 3 can be also with C&S flange.

Manual Operration:
1.With size-fixed cutting, the line can be used with a plasma cutting machine.
2.a.The line can notch angles for making“C”or“S”, profiles to match the corresponding lock formers.
b.With angle notching for all kinds of TDF joints, the line can be matched with TDF flange former & TDF folder.
3.Notch angle and fold for TDC flange to make “□ " square duct. Matched with pittsburgh lock former and TDC
flange former,the line can produce a whole duct.

FAQ:
How to make duct by semi automatic line:
Semi-Automatic Duct Making Process
1. Coil Loading & Sheet Preparation
Galvanized steel coil is loaded onto the decoiler.
The coil is leveled and straightened.
Sheet thickness and width are adjusted according to duct requirements.
2. Cutting & Feeding
The sheet is cut into required lengths by a shearer.
The operator transfers sheets to the next process.
3. TDF Flange Forming
The sheet passes through the TDF flange forming machine.
Four edges are formed with TDF flange profiles.
This creates strong connections between duct panels.
4. Lockforming / Pittsburgh Seam Processing
The duct sheet edges are processed by a lockforming machine.
The Pittsburgh seam is created for duct corner connection.
5. Duct Folding
The sheet is folded into a rectangular duct shape using:
Press brake machine
Manual folding machine
Hydraulic folding equipment
6. Corner Installation
TDF corners are installed manually.
Corner pieces are fixed with hammers or pneumatic tools.
HVAC duct line VI,the U-shaped structure not only saves the production site, but also reduces the delivery time of raw materials. The production efficiency is high (about 20-23 seconds per piece). The department fully automatically realizes the fixed size cutting, beading, automatic cutting ,the notching,pittsburgh forming, TDF flange and the angle iron flange ,automatically forming and bent into ”L“, ”U“, ”口“ shaped duct. Equipped with punching support air, common plate flange hole is optional.It has the advantages of high automation, high efficiency, labor saving and material saving.
Ventilation duct machine The air duct production line V is composed of feeding frame, leveling and beading, hydraulic punching point and square mouth, hydraulic shearer, movable pittsburgh forming machine,feeding platform, duplex flange machine, duplex angle iron flange machine (or double snap lock machine), servo feeding platform and TDF hydraulic folding. The computer control part adopts full computer control, bending with servo feeding, accurate positioning, especially when processing the bigger air duct, to ensure the bending accuracy.
Air Duct Machine Line Ⅱ is mainly for TDF flange blanking,meanwhile,it can be used for normal sheet blanking.Matched with TDF forming machine,pittsburgh lock former,folder and angle joint joint,the line can produce nice TDF ducts.
TDF flange forming machine applies both sides feeding and simultaneously shaping work mode, one side forming and one side forming is for installing hooks. TDF folder is with hydraulic,pneumatic,manual type.
TDC Flange Forming machine is the advanced technique in the world to manufacture square duct.It realizes standard,automation and mass production during producing rectangle flanges.
HVAC Quintuple Groove Beading Machine press the sheet with no limited length and form several reinforced veins.The veins are to stiffen the plate.Clients can order the machine according to thickness,width and number of beads on metal sheet.
Whisper-Lock Seam Closer is available in the horizontal or vertical and close pittsburgh seams.Pittsburgh joint is commonly used by manually hammering the margin of the seam against the duct wall(peening).It is suitable for plates of different thickness.To some extend,it can produce any size duct.
HVAC Corner Inserting Machine is Pneumatically powered, inserts corners into single-end or both-end(optional) in seconds automatically and crimps them into place.
Hydraulic fastener replaces screws or rivets.It is especially used in HVAC engineering,which joins two or more metal sheets together through cold extrusion without rivets,which is widely used in the western countries.
Angle iron flange punching and cutting including total 5 parts: Feeding device, major part, cutting device, hydraulic and electric system. PLC control system can improve accuracy , more effective and lower cost.
