INTRODUCTION
Your new Bender is a “Press-Style” Bender that is capable
of bending, flaring and swaging Tubing up to 3 inches in
diameter. The thickness of the Tubing plays an important
part in bending. (See Specifications for recommended
Tubing allowances.) The front of the Bender is where all
the bending is performed. The Top Cylinder activates the
Bending or Radius Die which moves forward through the
Back Shoes. The Bottom Cylinder keeps pressure applied
to the Back Shoes by a chain assembly and integrated
Hydraulic Sequence Valve. In addition to the contoured
shape of the Radius Dies, resistance pressure is applied
to help the Tubing maintain it's shape.
DEFINITION OF TERMS
The following definitions explain the major components
and operating features of your machine. The
RIGHT,
LEFT
, and
REAR
sides of the Bender are relative to the
FRONT
of the machine where all bending is performed.
BENDER-
The whole machine including all end
finishing components.
BODY-
The main 6” x 6” tubular structure that sits
horizontal to the floor and is located just below the Top
Cylinder.
SWAGING BOX-
The expanding/flaring unit located to
the rear of the Bender which utilizes Pipe Collars in
conjunction with bullet shaped Expander/Forming Dies to
perform a variety of Tube end finishing.
INTERNAL EXPANDER-
The Expanding/Flaring Unit
located to the rear of the machine that utilizes
Segmented Expander Dies. These “Segment Sets” are
expanded by the means of a tapered Arbor pulled through
their center. This style of end finishing is usually required
with shorter pieces of Tubing such as Muffler Nipples
which do not allow the use of a Collar.
TOP CYLINDER-
The main Hydraulic Bending Cylinder
located at the top of the Bender. Its primary function is to
activate movement of the Radius Dies.
BOTTOM CYLINDER-
The Hydraulic Cylinder located
just below the body of the Bender. Its primary function is
to apply resistance pressure to the Back Shoes as the
Radius Die pushes through.
RESERVOIR
- The rear vertical leg that contains the
Hydraulic Oil.
FRONT UPRIGHT-
The front vertical leg.
BENDER MODELS
There are three different Bender models available.
BB (Blue-Bullet) 1302-BAS 1302-BA
The following is a brief description of their controls and
operating features. The model nomenclature consists of a
number (1302) followed by letters BA or BAS. The
numbers designate what style frame assembly is used
while the letters signify the control features.
FRAME CONFIGURATION
1302 Series -
A machine capable of bending and end
finishing. Equipped with both a Swaging Tool and an
Internal Expander. A Double-Ended Hydraulic Cylinder is
used for both end finishing functions. The End Finishing
Assembly, (the Swaging and Internal Expander) is posi-
tioned “cross-wised” on the rear of the machine.
