HVAC duct line Ⅶ ,with 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, single hem folding, pittsburgh forming, TDF flange and the angle iron flange ,automatically forming and bent into ”L“, ”U“, ”口“ shaped duct. Equipped with punching support air, TDF flange hole is optional. Pittsburgh is formed before bending the short side of the large size duct.C+S flange is optional.It has the advantages of high automation, high efficiency, labor saving and material saving.
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.
Duct lock forming machines can process galvanized sheet with different thickness into various shapes,such as profile pittsburgh,single hem,double hem,snap hem,elbow,S shape and so on.
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.
