5.2. Visual Inspection
Regular inspections should be performed, and a
record of inspections should remain with the dies and
be provided to supervisory personnel responsible for
them. Tyco Electronics recommends one inspection
per month; however, amount of use, working
conditions, operator training and skill, and established
company standards should determine frequency of
inspection. The inspection should be performed in the
following sequence:
1. Remove all lubrication and accumulated film
from the dies by immersing the dies in a suitable
commercial degreaser that will not affect paint or
plastic material.
2. Make sure all die holding screws are in place
and secured.
3. Check all bearing surfaces for wear. Replace
worn components.
4. Inspect the crimping chambers for flattened,
chipped, cracked, worn, or broken areas. If
damage is evident, the dies must be repaired
before returning them to service. See Section 6,
REPLACEMENT AND REPAIR.
5.3. Gaging the Crimping Chamber
This inspection requires the use of a plug gage
conforming to the dimensions provided in Figure 3.
Tyco Electronics does not manufacture or market
these gages. Proceed as follows:
1. Remove traces of oil or dirt from the crimping
chamber and plug gage.
2. Actuate the tool, according to the instructions
packaged with the tool, until it is evident that the
dies have bottomed; then hold in this position. Do
NOT force beyond initial contact.
3. With dies bottomed, check the die closure using
the proper plug gage. Hold gage in straight
alignment with the crimping chamber and carefully
try to insert, without forcing, the GO element. The
GO element must pass completely through the die
closure.
