4.4. Die Closure Inspection
Every crimping head is inspected for proper die
closure before packaging. An inspection should be
performed periodically to check the die closure for
excessive wear. The die closure inspection is
accomplished using the GO NO–GO plug gages.
Tyco Electronics neither manufactures nor sells plug
gages. A suggested plug gage design and the GO
NO–GO dimensions of the plug gage members are
listed in Figures 7 and 8. the following procedure is
recommended for inspecting the die closures.
1. Clean oil or dirt from die closure areas, and plug
gage members.
2. Select the proper GO gage. Position gage
member in lower jaw inner crimp closure so that
locator is in notch of gage member. See Figure 9,
Detail A.
3. Close the crimping jaws until they are bottomed
but not under pressure.
4. To meet the GO gage conditions, the plug gage
must be free to rotate in either direction as shown
in Figure 9, Detail A.
5. Select the proper NO–GO gage. Position gage
member in lower jaw inner crimp closure so that
locator is in notch of gage member. See Figure 9,
Detail B.
6. Close the crimping jaws so that inner crimp
surfaces are seated on the NO–GO member.
