HVAC Machinery - Pittsburgh lock former machines
for Heating, Ventilating and Air Conditioning Duct work.
Buying
preformed HVAC duct can get very expensive, but you can form your own
with machines and tools for forming sheet metal into shapes for Heating,
Ventilating, and Air Conditioning duct work. Cutting can be done using
hand shears, a rotary slitter or
sheet metal shear. 90 degree bends can be formed on "easy edger"
right angle flanger or a sheet metal hand brake.
A few other simple shapes can be bent using a bar folder, cleat or cheek
bender but these methods are slow. More complex shapes and longer lengths
are best formed on a HVAC roll forming machine also known as a lockformer
machine. Pittsburgh lock, Drive Cleat, and ACME Double Seam are made
on a machine with at least 5 sets of roller dies. Button Snap Lock and
S clip need 9 sets of roller dies. If you need to feed lots of metal
to a rollformer consider using an uncoiler.
To form elbows use a manual or powered right angle flanger and slip
rolls. Take careful note of the minimum and maximum allowed metal
thickness and also the electrical requirements of any machine you are
considering. The S & Drive Former, Button Snap Lock or Fourplex
Cleat Former machines are normally 220 volts, 3 phase with optional
1 phase 220 volts costing extra. Some less expensive machines are designed
for use in small shops, others may cost more but are for frequent heavy
use. Many of our machines are made in USA such as Flagler and RAMS.

DUCTFORMER TDFC BRAKE Our
Ductformer TDFC Brake is for bending the 90 degree bends on
rectangular duct work. It is a very efficient machine to bend
straight duct joints and fittings with TDC type and TDF type
flange connectors. Designed so one operator can quickly slide
a piece of sheet metal into the machine and align the notches
in an instant on the alignment blade located at the bend line.
Other styles of ductwork such as Slips and Drives or straight
duct can also be folded over or bent to 90°. The machine can
also fold any angle less than 90 degrees. |
