Cold forming
mechanical
transfer press
INVERNIZZI Presse’s 12,000kN
GNLMt2 1600–750 knuckle
joint transfer press with
advanced control system
allows an easy connection
of the press to the complete
production system, to
provide completely automatic
equipment.
The press can incorporate
options such as out-going
table, for an easy and fast tool
exchange, lower and upper
ram extractions, and 2D and
3D transfer. The flexibility of
the equipment allows it to
be used in a wide range of
applications.
Advantages include low
cost of tool material; low
forming speed; no costs for
material heating; no material
tolerance problems due to
material restriction; improved
surface and mechanical
characteristics of finished
parts; high production rate;
and longer tool life.
The press linkage is composed
of a modified knuckle joint
with added link points, while
the press frame is produced
in separate stress relieved
welded steel units assembled
by cold preloaded tie rods
(hydraulic controlled system).
Oversizing of the frame and
control drive system ensures
maximum static and dynamic
rigidity. The control panel
uses a Siemens MP 277 TFT
touch-screen.
The ram is guided with special
pre-charged clearance free
roller guides. This system
ensures accuracy and
efficiency even with displaced
load, as well as low working
friction.
