Lateral forces occur during fineblanking.
It therefore makes sense to absorb these lateral forces in
large size die sets with plain or roller bearing bushings.
The initially higher costs are easily compensated for by the
longer tool life.
The blanking force is directly transferred to the die plate
by the bottom die shoe.
The V-ring force (stripper force) is transferred to the V-ring
plate (stripper) by pressure pins. The counter force (ejection
force) is also transferred by pressure pins to the counter
punch (ejector). |
