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. (See previous chart 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.
SWAGER OR SWAGER 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 five 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. 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 swager and internal
expander. A double-ended hydraulic cylinder is used for
both end finishing functions. The end finishing assembly,
(the swager and internal expander) is positioned
“cross-wised” on the rear of the machine.
