Advantages of the
GRABENER knuckle-joint system
Typical of GRABENER knuckle-joint presses is the
extremely rig d press construction and favourable
time-path sequence n the embossing area.
The principle:
The press frame fLrnctions as a ram wh ch is moved
downwards by tfle knuck e-loint. The bo ster plate
and press housing are rigidly connected
to each other
The advantages:
The softer mpact ofthe die on the coin, compared
with other drive types, and the length er contact

On multFstrike operation, the roli is swLrng away from
the drive cam. The ejector is deactivated
for a programmed number of strokes. With a second
pneurnatic cy indet the bottom dle can be moved into
the c ean ng position above the ejector

Upper and lower tool rith
wedge-type adjust m( enr
The errbossing too consists of an upper and ower tool
with wedge-type adlustment. Adjusting the wedge at
the upper tool for applcation of the press force is ear y
done with repettive precis on with the he p ot a
geared motor. The adjustment path and press force are
shown on the operator panel disp ay. W th the wedge
adjustment at the lower tool, the embossing die can
be postioned accurately n the embossing co lar.
f
Fast tool change with
hydraulic quick-clamping
tool ch uck
To minirnize tool-change time, we have equipped the
presswth a hydraulc quick-camp ng toolchuck. The
embossing die is c amped in the direction of the
embossing force to ensure t remains firrnly clamped
even under load.
Lower-cost change parts
Hydraul c tool clarrp ng makes re too ing eas er and
qu cker t a so alows the use of favourably priced
change parts.

. Upper tool disengagement
eliminates dust nuisance on multistrike
operation
The fourfold colLrmn guided upper tool is disengaged
from the press frame during multi strike operation and
remains in the embossrng co lar in contact
wiits rhe Lo n.
Dust turbulence on opening the tool s avoided.
Universal ball joint for adaptation
to eccentric relief
Mounting the upper tool in an adjustable un versal bal
joint allows the die to be adapted
for eccentric rel efs
