2.
Remove the tubing from the die block and deburr
the inside and outside edges.
3.
Install compression couplings on tubing and dip end
of tubing to be flared in hydraulic fluid. This lubri-
cation results in better formation of the flare.
4.
Place on-half of the die blocks in the tool body with
the counterbored ends toward the ram guide. Now
lay the tubing in the block with approximately 1/2"
protruding beyond the end.
Fit the other half of the block into the tool body,
close the latch plate and tighten the nuts "finger
tight".
5. Select the correct size upset flare punch. One end
of this punch is counterbored or hollowed out to
gauge the amount of tubing necessary to form a
double lap flare. Slip the punch into the tool body
with the gauge end toward the die blocks. Install the
ram; then tap lightly until the punch meets the die
, blocks and they are forced securely against the
stop plate (fig. 13).
6. Using the supplied wrench, draw the latch plate
nut down tight to prevent the tube from slipping.
Tightening the nuts alternately (beginning with the
nut at the closed hole in the plate) will prevent
distortion of the plate. Remove the punch and the
ram. Now reverse the punch and put it back into the
tool body. Install the ram and tap it lightly until
the face of the upset flare punch contacts the face
of the die blocks (fig. 14). This completes the
first operation. Remove the ram and the punch.
7. To complete the flare, insert the pointed finish
flare punch and the ram into the tool body. Tap
the ram until a good seat is formed (fig. 15).
NOTE:
The seat should be inspected at inter-
vals during the finishing operation to avoid
over-seating.
