To develop maximum power, the riveter
must drive the rivet near the end of the riveter's stroke. For maximum
power the combined length of the two rivet sets must be of the correct
length. Determine the correct length as follows:
WHEN TWO CUPPED RIVET SETS ARE USED
The sum of the two rivet sets "L" dimension should equal the closed height
dimension of the yoke minus the total thickness of the material being
used.
WHEN TWO FLUSH SETS ARE USED
The sum of the two rivet sets "L" dimension should equal the closed height
dimension of the yoke minus the overall length of the rivet after it is
driven.
WHEN ONE CUPPED SET & ONE FLUSH SET ARE USED
The sum of the two rivet sets "L" dimension should equal the
closed height dimension of the yoke minus the total thickness of the material
being riveted and the height of the finished rivet head driven by the
flush set. If necessary, select rivet sets a little short and shim to
proper length with hardened shims listed in the table. The closed height
dimension of the yoke referred to above is the opening available when
jaws of plunger are in extreme closed or forward position with both rivet
sets in place.
