Crimping Die Assemblies
408-8705
3.2. Insulation Crimp Adjustment
This adjustment is made to both stationary and
moving dies after they have been placed in crimping
head.
NOTE
i
Crimping Dies have four socket head cap screws
and two pin-keys for insulation crimp adjustment.
1. The dies have three insulation crimp positions.
The adjustment is made by moving a pin–key (see
Figure 1). When the pin–key is pushed all the way
in, the insulation crimping section of the die is in
the loose position; when the pin–key is halfway
out, the insulation crimping section of the die is in
the medium position; when the pin–key is all the
way out, the insulation crimping section of the die
is in the tight position.
2. To adjust the insulation crimp, loosen socket
head cap screws and push pin–key all the way in
so that insulation crimp section of the die is in the
loose position.
3. Press and hold insulation die down against the
pin–key. This will prevent the spring–loaded
pin–key from popping back.
4. Tighten socket head cap screws.
11. Refer to Paragraph 3.4 and Figure 4 for crimp
inspection procedure.
3.3. Color Code
Terminals and dies are color coded as listed and
shown in Figure 1. The dies have the terminal size
stamped in the wire barrel crimp sections of both the
moving and stationary dies. When crimped, the wire
size will appear on both sides of the terminal wire
barrel. The wire size appearing on the crimped wire
barrel should always agree with the wire size stamped
on the terminal tongue.
3.4. Crimp Inspection
Inspect crimped terminals by checking the features
described in Figure 4.
NOTE
i
AMPLI-BOND terminals are shown in Figure 4.
Inspection procedure is the same for AMPOWER
and PLASTI-GRIP terminals.
Use only the terminals that meet the conditions
shown in the “ACCEPT” column. “REJECT” terminals
can be avoided through careful use of instructions in
Paragraphs 3.1 and 3.2, and by performing regular
die maintenance described in Section 4.
NOTE
i
Make certain insulation crimping sections of
moving and stationary dies are both adjusted to
the same position.
5. Perform a test crimp (refer to Paragraph 3.1).
NOTE
i
AMPLI-BOND and AMPOWER terminals provide
a grip" on wire insulation. PLASTI-GRIP
terminals provide only a support" for the wire.
6. Remove crimped terminal from dies and visually
inspect the insulation crimp portion of terminal. The
insulation crimp should “grip” wire insulation (when
using AMPLI–BOND or AMPOWER terminals) or
provide “support” for wire insulation (when using
PLASTI–GRIP terminals).
7. If the insulation crimp does not grip or support
wire insulation as described in step 6, loosen
socket head cap screws and set the pin–keys in
the medium position. Then follow Steps 3 and 4.
8. Make another test crimp over previously
crimped terminal.
9. Remove crimped terminal from dies and visually
inspect insulation crimp.
10. Repeat adjustment as necessary until desired
insulation crimp is obtained. Do NOT use a tighter
setting than required.
4. MAINTENANCE/INSPECTION
Regular inspections should be performed by quality
control personnel. A record of scheduled inspections
should remain with the dies and/or be supplied to the
supervisory personnel responsible for the dies.
Though recommendations call for at least one
inspection a month, the inspection frequency should
be based on the amount of use, ambient working
conditions, operator training and skill, and established
company standards. These inspections should be
performed in the following sequence:
4.1. Cleaning
Do not allow deposits of dirt, grease, or foreign matter
to accumulate in the die closure area, or on the
bottoming surfaces of the dies. These deposits may
prevent the dies from bottoming fully and may also
cause excessive wear in the die closure surfaces,
thereby affecting the quality of the crimp. The dies
should be wiped clean frequently with a clean cloth.
4.2. Visual Inspection
Visually inspect the die closure surfaces for flattened,
broken, pitted, or chipped conditions. Although dies
may gage within permissible limits, worn or damaged
die closure surfaces are objectionable and can affect
the quality of the crimp. Examples of possible
damaged die surfaces are shown in Figure 5.
