Applications
MAIN FEATURES
Main caracteristics of an EMG mechanical press :
Frame :
The frame is made of high quality mechanized-welded steel with swan-neck structure. Regular weld seams and proper welding supports ensure an exceptional rigidity and a resistance against cutting impacts even during an intensive use.
The very thick sides of the frame reduce the swanneck opening.
Shaft :
The shaft is made of hardened forged steel. An over-sulfinization after machining reduces the wear and tear due to friction. It runs on lubricated rings.
Stroke change :
The stroke change is achieved very quickly by turning the disconnecting device a ¼” of a turn and then selecting the desired Stroke length.
Slider :
The slider is made of cast iron FGS 300 mounted on steel or bronze sliding rails, adjustable by screws. The assembly is completely adjusted and scraped manually.
The adjustment is carried out by stops mounted on the press frame.
The bedplate of the slider has holes and a central bore for fixing tools.
The sliding rails have machining in the form of "oil grooves" allowing an efficient lubrication.
A knock-out bar goes through the slider. The adjustment is carried out by a stop mounted on the frame.
Lubrification :
The lubrication is centralized and ensured by a manual pump. The frequencies are to be adapted as per the cycles used (single or continuous stroke working).
Automatic pump (optional).
Twin-body solenoid valve :
It is self-controlled and assembled with heavy duty silencers.
Connecting rod/Swivel screw :
The connecting rod is made of FGS 300 cast iron (steel on 88T) with bronze line completely scraped ensuring a perfect lubrication. It is lubricated by oil.
The swivel screw is made of pre-treated steel, completed by a surface treatment.
Clutch/Brake :
The movements of the press are obtained by a monodisc air clutch and managed by a brake. An air reservoir compensates for the possible failures of the network starting from the 27.6t model.

APPLICATIONS
EMG has developed a range of mechanical presses from 6.6 tons to large tonnages (88 tons) particularly adapted to the stamping of all types of sheets. They are also adapted to the cutting/forming of complex parts thanks to the easy management of the force and the control of the pressure exerted throughout the operation.
How does a mechanical press work?
All the mechanical adjustments on board the press make it easy to adjust the speed, headroom and ram travel required for the application.
Bronze guides guide the ram as it descends from top to bottom, to ensure perfect alignment between the lower part of the tool fixed to the table and the upper part of the tool fixed to the ram. The strength of the frame's gooseneck counterbalances the considerable force applied (up to 88 tonnes) by the ram.
Faster than hydraulic presses, they offer very high repeatability with a low risk of breakdown.
