The diagram shows a base
plate which is used in the
Flex Cam (1) to cant (bend
up) lateral tabs (2).
Working sequence:
The bending punches fixed
to the Cam Units (in this case
Flange Cams) are supported
at the sides (3). These sup-
ports absorb the severe late-
ral forces resulting from the
bending operation.
Without this system, it would
have been necessary to pro-
duce an entire new tool with
a floating die or to introduce
a second operation.
This tool has two Force
Cylinders for driving an
800 mm wide bending
punch.
Working sequence:
As can be seen from the
diagram, the blank is bent
(1) at an angle, against the
motion of the press.
Two separate Flex Cam to
synchronise the motion of
the bending punch. Each
system consists of a Power
Unit (2) and a Force Cylinder
(3).
The bending punch (4) is
guided in the tool. As a
result, the Force Cylinders
only absorb axial forces.
Use of the Flex Cam simpli-
fied the structure of this
tool, thus reducing the
machinery costs.
