Operation: General Information
Basic Operation
Most of thi s manual is devoted to showing you how to make some common
parts at a typical size. Other than those specific instructions, setting up the
Bender to lorm your particular parts will involve a certain amount of trial
and-error.
You will notice some differences in operation depending on whether you are
forming the piece around a die, or whether you are making a sharp-angle
bend in the piece. However, in general you will:
1.'
Determine the appropriate material and size for the part(s) to be made,
2.
Determine the appropriate dies to install on the center pin and/or the pin
installed in the handle. Determine the appropriate hole for attaching the
handle to the ring assembly's loop.
3.
Install the stop block or the sharp-angle-bend attachment, as appropri
ate. Install the block support. If the stop block is used, orient
rt
properly.
Refer to pages
6
and
7
for more information on the slop block and the
sharp-angle-bend attachment.
4.
Insert Ihe blank stock into the Bender, and position it properly for Ihe firsl
bend.
5.
Make the first bend. Recheck the angle and location before continuing.
6.
Make any addrtional bends in the same way. In some cases, you may
5
have to remove the piece from the Bender and turn
rt
end-for-end or '
upside-down.
Hole Identification
In the examples shown in this manual, the holes in the loop and those inthe
handle are identified by a number. Refer to the illustration at right.
Measuring Bend Angles
.
When accuracy is required, you will need a suitable device for measuring
the bend angles.
Fixed and Adjustable Stops
If you are making mu iple parts with the same bend angle, using the same
setup (dies and hole locations), the operation will be speeded up by install
ing either the fixed or adjustable stop in the appropriate hole in the ring
assembly.
After determining the handle rotation, insert the fixed stop into the next open
hole and use it as a guide for bending additional parts
. •
When greater precision is required, attach the adjustable stop as accurately
as you can at the limit of handle rotation. Make a test part with scrap mate
rial,
and reposition the adjustable stop as necessary. Tighten the bolt and
nut securely before bending production parts.
Notes
•
If precise dimensions are required, start by making a test part using
scrap material olthe samethickness. Readjust the setup as necessary .
•
Once you determine the dimensions, die size(s), holes, and bending
sequence for
a
part, write down the information for future reference.
