TP 11⁄4 & TP 23⁄8
Units
These units provide two sided
punching in round or square
tubes. Each assembly top and
bottom contains a Punch to
pierce two holes in-line on
each side of the tube.
The tubing is supported on
all sides during punching.
If only one hole is desired, the
removal of the bottom Punch
accommodates this option.
The Units require upper and
lower Templates. One template
is attached to the Ram of
the Press, the other to the
bed. A tube is placed into the
lower assembly, the Ram is
then lowered for line up
adjustment, and the units are
then secured to the Templates
and are ready to punch holes.
Due to lack of Die,
unsupported tubes distort
when punched. |
TP-2 Units
This self contained ‘C’ Frame Unit utilizes pilot pins in the bottom
of the holder for mounting on 1⁄2" thick Templates with nothing
attached to the Press Ram. The tubing is supported on all sides during
punching. The Units provide straightthrough holes with one punch. The top
hole has distortion, which varies depending upon Punch size, tube OD, wall
thickness and material type. The bottom hole is punched into a die, providing
minimal distortion.
