technical description

Slim stand principle with 500 mm free passage. The stands are provided with
swivel bearings on which the table is placed. On the one hand, the cylinders
are screwed between the side stands and clearly positioned by means of wedges.
On the other hand, the cylinders are bolted to the support at the front and
rear, resulting in a stabilizing frame construction.

The hydraulic tank is screwed between the side stands and contains all the
block hydraulics for controlling the individual machine elements such as the
tappet drive, tool clamping, die slide device, etc.

The movement of the plunger is controlled by electronically controlled
proportional valves, a gray scale being provided on each side of the plunger
for precise measurement of the position. Both the parallel position and the
exact lower action point position are controlled by the CNC control via the
valves mentioned, with a stopping accuracy of 0 / - 0.01 mm being maintained at
the bottom dead centre. The frame suspension (frame on suspension) is
compensated on both sides by mounting the gray scales on separate supports that
are attached directly to the table.

The ram is rapidly advanced by ancestors under the influence of its own weight,
whereby the press cylinders are supplied with oil by means of large suction
valves. After the switchover point from the forward speed to the working speed
has been reached, the plungers are supplied with oil from the main pump via the
proportional valves.

The steel press cylinders are double-acting, with the piston rods being
connected to the ram by cambered supports and elastic intermediate links. A
safety control independent of the electronics registers the parallel position
of the ram and switches the machine off immediately if, due to a fault in the
electronics of the ram, it does not remain in the parallel position. Otherwise,
the dangerous functions of the hydraulics are automatically checked and secured
in accordance with the latest accident prevention regulations.

The electrical cabinet on the right side of the machine essentially contains
the power section, the computer section and the safety section. The connections
from the electrical box to the mechanical part are made using plug connections.

The machine and accessories comply with the currently applicable provisions of
Directive 89/392 / EEC (machines) amended by Directives 91/368 / EEC and 93/44 /
EEC.

The machine price includes the required side and rear protective grilles and
two-hand operation with a safety stop.
