AMERICAN STYLE CURLING DIE SETS |
| |
|
 |
CU-1 / CU-2 Curling Die Set |
|
The CU-1 and CU-2
curling die sets when used in
combination with each other form the
tightest, most accurate off-center curl
available in two press strokes. For
progressive forming the die sets can be
made with matched shut heights |
|
 |
CU-1 / CU-3 Curling Die Set |
|
The CU-1 and CU-3
curling die sets form an off center curl
in three stokes or an on-center curl in
three strokes. To maintain the diameter
of the curl the part should be closed
over a mandrel in the third operation.
|
|
|
|
CU-4 Curling Die Set |
|
The CU-4 curling
die set forms a complete off-center curl
in three operations. Whip-up is kept to
minimum because of the small angle
involved as the material travels through
the first two operations. When forming
heavier materials, a leader can be added
to the backside of the punch which keeps
the punch and die form spreading.
|
|
|
|
CU-5 Curling Die Set |
|
The CU-5 curling
die set forms a complete off-center curl
in three operations or an on-center curl
in four operations. To maintain the
diameter of the curl the part should be
closed over a mandrel in the third
operation. A leader is added to the
backside of the punch which keeps the
punch and die form spreading.
|
|
 |
CU-6 / CU-7 Curling Die Set |
|
The CU-6 and CU-7
curling die sets are useful in forming
larger diameter curls in three stokes.
Three operations used in conjunction
with both die sets will produce a closed
curl, while an open curl up to 180° can
be formed with just CU-6. Both dies may
be placed next to each other for
progressive forming.
