4-4. Forming method when you use forming jig
1. Preparation of the jig for forming
・
Prepare the jig for forming. (There is a commercially
available product.)
・
Attach the pin (Example 1) or the bolt and nut (Example 2)
by dividing equally into 3 portions onto the ring shape
plate. Make the ring into a shape with sufficient thickness
which does not distort.
2. Gripping of the jig for forming
・
Operate the switch valve and maximize the opening of the
jaw. Then, operate the switch valve to insert the jig for
forming into the bolt hole of the soft jaw to grip. At this
time, grip by pressing the ring end surface of the jig for
forming onto the jaw so as not to generate run-out.
・
Check that it is gripping almost in the center of the
appropriate stroke.
・
Set the hydraulic pressure when forming slightly higher
than when processing the work.
3. Forming
・
Process the gripping part (dimension
φ
D’) of the work in
the state that the jig for forming is kept gripped. The
φ
D’
part is to be approximately the same diameter (H7) as the
diameter of the gripping part of the work, and process to
be surface roughness at 6s or less.
4. Trial cutting
・
Remove the jig for forming and grip the work to check the
jaw stroke.
・
Implement trial cutting to check the process precision and
that there is no slip, etc.
・
Contacting on the gripping surface is to be 2 points contact
of the side A and the side B when gripping.
