Flex Cam
Typical Applications
Application: Punching holes with a Flex Cam
Stroke ratio 1:2.5
°
This tool produces two workpie-
ces at the same time: one on the
right and the other on the left. On
the left-hand side of the diagram,
the press is at the top dead centre
position. On the right-hand side,
the press is at the bottom dead
centre. The transport grippers can
be seen above the Cam Units.
The workpiece must be shaped
before the holes are punched in
the sides.
The machining contour requires a
relatively large distance between
the blank and the punching unit.
Working sequence:
A small Cam Unit (1) is connected
to a larger Power Unit (2) in order
to guarantee the necessary
time/traverse sequence. This
results in a stroke ratio of 1 to 2.5.
Example: If the Power Unit stroke
is 10 mm, then the Cam Unit stro-
ke will be 25 mm.

Application: Cutting with floating suspension and conical
spacers
°
This application uses a Flex Cam
that is suspended from above (in
the top part of the tool).
Working sequence:
The Cam Unit (1) is mounted on a
floating die (2). The floating die is
spring-mounted and is centred
with respect to the bottom part of
the tool by conical spacers. As the
press moves down and the floating
die is centred, the Power Unit (3) is
activated and the holes are
punched.
Before the Flex Cam was installed,
the holes were punched vertically
using oval forming punches.
Due to the improved production
output and quality that resulted
from installing the Flex Cam, the
system paid for itself (including
installation) within just three
months.
