Built into the Model 4 tubing bender is a degree ring nearly 20
inches in diameter. Each degree increment is nearly
3/16" apart. This makes it incredibly easy to see
exactly how far you have bent. There is no need to adjust a
pointer because there isn't one. Simply look at the right
edge of the lower drive link, note the degree, add your
desired bend angle to it and start bending.
Duty Construction !!!
You can get a good idea of the size of the Model 4 in the
picture if you consider the tubing mounted in the bender is
1 1/2" (38 mm) outside diameter. It weighs 166 lbs.
with the hydraulic cylinder alone. With the 1-1/2 h.p. pump,
it weighs 225 lbs. It's 28 1/2" long and 20" wide.
All links and frame are precision CNC machined from
3/4" and 1" thick steel. All pins are high
strength steel. Talk about overkill, even the frame bolts
are 1" in diameter by 8" long. All Model 4 die
sets are precision CNC machined from solid steel billets.
To Be Reliable !!!
Painstakingly designed to last years in a hard working
fabrication shop. The hydraulic cylinder for instance,
swivels in a solid CNC machined steel block that pivots
exactly at the cylinder's center, thereby preventing side
loads on the cylinder's internals. The pusher block, seen in
the lower center of the above photo, employs a unique
rotating design and a swiveling bronze wear block so that
the cylinder will not experience any up or down loading.
Locking, Hydraulic Operation !!!
The Model 4 employs a 10 ton single acting spring return
cylinder with a stroke of 14". It operates up to 4000 p.s.i.
With the recommended 14" stroke cylinder, 90 degree bends
can be accomplished in less than two complete strokes and
180 bends typically require only three strokes.
During bending, neither the die set nor the work piece needs
to be reset or touched in any way until the bending
operation is complete. Using the spring loaded anti-springback
lever, the Model 4 will lock the work piece in position when
the cylinder needs to be advanced to the next stroke
position, therefore not allowing the work piece to relax or
shift in the bender. This makes possible much tighter radius
bends in thinner wall material then can be accomplished on
competing benders. Using the 14" stroke cylinder, the
first bend stroke can be up to approximately 60 degrees.
The second stroke will go to approximately 126 degrees.
Bending speed is dependent upon the strength of the material
being bent. Usually 6 to 10 degrees of bend per second will
be realized. The 14" stroke cylinder takes 8 to 9 seconds to
return from full extension. Add it all up and a typical 90
degree bend will take an effortless 20 to 25 seconds,
depending on the operator's skill level.
Tech 3D Bending Software is
a tube and pipe design and layout software, using templates for
data entry. It is designed to minimize waste in
manufacturing and fabrication operations by eliminating off-cuts
and errors associated with manual calculations. Great for
any tube bender!
Angle Finder Take the guess work out of measuring angles
in your tubing. It's digital and it's easy to read!!!
Notchers How are you going to build a roll cage without
a tube notcher? I guess you could do it the hard way with a chop
saw... or you can save some time and do it right with a quality,
USA made notcher. Copes tubing from 3/4" up to
