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

Frsessen-

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
