HVAC Machinery - Pittsburgh lockformer machines
for Heating, Ventilating and Air Conditioning Duct work.
Since
buying your preformed duct can get very expensive, this webpage has
machines and tools for forming sheet metal into shapes for Heating,
Ventilating, and Air Conditioning duct work. Cutting is 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 formed using a bar folder, cleat or
cheek bender but these methods are slow for big jobs. More complex shapes
and longer lengths are best formed on a 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
CleatFormer machines are normally 220 volts, 3 phase with optional single
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.
