SCHMIDT ® HydroPneumaticPress
Maximum Force Range from 15 kN to 220 kN
The SCHMIDT ® HydroPneumaticPress range consists of a
modular system suitable for transforming, joining and assembling optimally within the pressing force range 15 – 220 kN.
With the addition of the SCHMIDT ® PressControl 75 or 600 and
the optional process monitoring, these presses become EC typeapproved, CE-conformed workstations. Therefore these press
systems can be used in either single cycle mode or automatic
mode.
The application determines selection of the press system. Consideration is given to the flexible design of the assembly location
taking into account the ergonomic and safety aspects. These
characteristics are achieved by means of a finely adjusted, modular
type product range. The efficiency and increased process reliability of these press systems have been proven many thousands
of times, in single applications, semi-automated assembly
systems and have been integrated into automated production
lines.

1
Cylinder Unit
Hydro pneumatic
2
Air Throttle Rapid Approach Stroke
For speed control of the downstroke
3
Press Head Unit
The working height can be rapidly & accurately adjusted due
to the height adjustment’s ease of use. Can be used without
the frame as processing station in automated installations
4
Pneumatic Control Package
Two-channel pneumatic package (as shown) is based on a
modular valve block
5
Force output Preselector
The press force output can easily be controlled via a separate
pressure regulator and pressure gauge. The pressure for the
power stroke can be reduced to 1 bar
6
Square Ram
Square ram with fully adjustable, Teflon lined gibs for precise
travel, precision machined bore
7
Frame
With precision machined press head guide rails (for No. 68
and 368 designed as dovetail guide)
8

Power Stroke
Rapid Approach Stroke
In rapid approach stroke, the air connections 1 and 4 are pressurized with compressed air. The air connections 2 and 3 are
depressurized. The approach stroke piston 6 and the reservoir
piston 7 are moving with low force until the ram 5 encounters
resistance.
Power Stroke
If the ram 5 encounters resistance, a valve switches the compressed air from 4 to connection 3 , and the power stroke piston
8 moves downwards. A rod enters the high pressure cylinder,
separating the hydraulic oil between reservoir piston 7 and approach stroke piston 6 . The ram 5 moves out with boosted
force.
Return Stroke
For the return stroke, the connections 1 and 3 are depressurized, and the connections 2 and 4 are pressurized. Approach
stroke 6 and power stroke piston 8 move back simultaneously.
After the hydraulic connection between approach 6 and reservoir
piston 7 oil flows back into the reservoir, moving the reservoir
piston into its home position.
Return Stroke
Features
Optimally adapted to individual requirements due to its modular
design
High flexibility and economic efficiency due to short changeover
times
Easy and accurate positioning of tools due to the precise alignment
between ram bore and the ground fixture mounting platen
The force output preselector allows reducing the pressure for
the power stroke to 1 bar. This reduces the nominal press force
to 1 / 6 of the maximum force.
The end positions of the ram can be sensed via the inductive
proximity switches.
No mechanical compression spring in the cylinder of the hydropneumatic system, providing a long service life
Low maintenance resulting in high productivity
Long service life and precision due to maintenance-free guides
Tool protection due to smooth switchover from rapid approach
stroke to power stroke
Additional safety when using heavy tools due to the optional
ram drift lock device for retention of ram in home position.
Low noise level (< 75 dBA)

Accessories
High-pressure Switch
After switching from rapid approach stroke to power stroke,
the oil pressure rises in the hydraulic chamber of the cylinder.
The high-pressure switch can be
adjusted to reach a determined
press force through the output
generated by the oil pressure in
the press.
Adjustment Bushing for
SCHMIDT ® HydroPneumaticPress No. 74 and 76
For a simplistic adjustment of the
working height with a setting
range of 100 mm. This greatly
reduces the need for spacers to
accommodate different working
heights during setup changes.
Oil Pump
For an air-free refilling of the
SCHMIDT ® HydroPneumaticPress with hydraulic oil., including 1 liter Hydraulic oil.
