ALFAMATIC Press-Right, User Manual, Page: 5 / 42

1 General information
Press-Right is a monitor and measuring device that is connected to a press and monitors the quality
of productive processes.
Being interfaced with a displacement transducer and a load cell, it continuously monitors its
positions and instantaneous force.
1.1 Introduction to the monitoring theory
During sample production, the data regarding cylinder position and the force exerted by it are
entered; the following graph may be created: position-force representing production.
If several runs are performed on similar pieces, their position-force curves will also be similar. On
the other hand, if one of the manufactured pieces is different from the sample, its curve will be
different from the sample. It is clear that monitoring the curve may affect the quality of
manufacturing.
This product must not be disposed of as an unsorted urban waste; secure proper
recycling.
1.2 Characteristics of the device
Press-Right manages and monitors the profile of the cylinder speed.
It works on a continuous tolerance range monitoring the whole position-force curve.
It monitors the peak position and the peak force values.
It stops the press once a position target or force target is reached.
It monitors the initial height measured upon contact with the piece.
It monitors critical points through position-force curve
check point s.
It manages up to four consecutive phases with independent parameters.
All parameters are saved in 200 independent and selectable jobs.
Advanced management of users by means of passwords and personal authorizations.
Press-Right may be connected to the computer and, by means of the WinScope software, it may
save curves, edit settings, run statistical analyses, print data.
Saving curves on the SD memory card.
It allows the connection of up to three enabling signals.
It allows the connection of up to three additional OK/NOK check signals.
Programmable periodic self-verification function.
Programmable periodic request for the replacement of worn-out tool.
Programmable periodic request for maintenance.
1.3 Device operating principle
The Press-Right PE is sold together with an electric press: it measures the position of the cylinder
instant by instant, and the force exerted by the cylinder by using a force transducer instant by
instant.
In order to increase the precision of its height, it may be associated with an external micrometric
probe.
The work phases (pressing) are performed as follows:

Fast approach up to a
END APPROACH POSITION
at the
APPROACH SPEED

Pressing job at the
WORK SPEED
up to the
FINAL POSITION
or up to the
STOP FORCE

Stationing on the piece for a time set as
WAITING BEFORE RETURN

Return to the
RETURN POSITION
at the
RETURN SPEED
