TOX®-PowerKurver.............................................................................................................................................................

Function:
The piston of the TOX®-PowerKurver, when pressurized withair, pushes the high capacity rollers against the cam surface
in the cam lever. The in-house developed and patented cam
shape produces a constant force over the adjustable stroke.

Advantages:
 Part accessibility
 Higher force compared to toggle lever Force in hard to reach places Robust pneumatic cylinder drive Clamping and Clinching at the same time

The TOX®-PowerKurver offers the following features:
 Constant Force-Travel characteristic
over the working stroke
 Fast approach stroke Smooth power stroke initiation
 High press forces with low air pressure Low air consumption
 High stroke frequency
 Compact design Adjustment possibility of longitudinal andtransverse tool axes

Modular system
Our modular system gives you the freedom to match theTOX®-PowerKurver to your specific requirements. We solve
your application and quality assurance requirements withclear defined interfaces.

The TOX®-PowerKurver consists of the base unit KK 90,
the jaws, the tools and accessories. The jaws, tools andaccessories are matched to your specific requirements.
Following are the technical details of the base unit. The
complete unit is referred KKG.

TOX®-PowerKurver with pneumatic drive.............................................................................................................................................................

Technical data:
The press force depends on the throat depth and opening
between the tools. Refer to the diagram shown on this page.
The KKG 90 generates 60 kN at 100 mm throat depth and
8 mm tool opening. At the end of the stroke it provides up to90 kN over a travel distance of 3.5 mm.

Scope of delivery:
The TOX®-PowerKurver assembled according to ordernumber. The jaws are not included with the base unit andneed to be ordered separately.

In punching operations only 50 % of the nominal force of theTOX®-PowerKurver may be utilised.
Opening angle:
There are two main positions: 90° opened and 0° closed.
The working range of the TOX®-PowerKurver lies in between
these values. The distance between the tools during theapproach stroke is designated as the tool opening. For
various reasons, it might be necessary to restrict theopening angle. The TOX®-PowerKurver can be orderedwith standard opening angles of 30° / 45° / 60° / 75°. Please
specify the required opening angle as shown in the ordering
example.
