OmniLink TSM - Tonnage and Signature Analysis Module
Take a giant step forward in on-line metalstamping process and quality control at a reasonable
price. The OmniLink 5000-8A Tonnage Signature Monitor and Analysis Module,
TSM, allows the OmniLink 5000 control to monitor and graphically display
the force signatures produced in press production Systems.
Unlike peak tonnage monitors which can only monitor and display the tooling that punches the highest
tonnage during the stroke, the TSM stores up to 4735 samples of the tonnage
that occurs throughout the stroke and record the crankshaft angle at which
each sample is taken. This ability provides the information
necessary to display and therefore analyze and optimize tooling design
for the part produced and to pinpoint specific tooling, material, and press
problems in the stamping process.
Truly, the OmniLink 5000-8A TSM provides a new dimension in metalstamping process
setup and control.
Below are two of the screens for the OmniLink 5000-8A TSM.

Figure 1 shows the bar graph display for a four channel configuration. Each
channel window shows the actual tonnage measured by the strain link for
that channel, the hight and low setpoints, and a color bar which
gives a quick visual indication of the tonnage on that channel relative
to its setpoints.

Figure 2 shows the actual
tonnage waveform registered by the strain links. This particular
screen shows the total tonnage, the angular values for the window displayed
(configurable), and horzontal bars giving a quick visual indication of
where the data windows are set. In addition, each individual channel
may be displayed graphically. |
Features
Data windows allow monitoring of significant tonnage signature features throughout the stroke
Easy to view tonnage signature displayed graphically on the OmniLink LCD
Operator Terminal for each strain link channel
Initial Setpoint limits may be entered manually or automatically determined
and set by the TSM after a 16 stroke signature sample.
Stores and recalls high and low setpoint limits and angular position of all data
windows used and peak tonnage setpoint limits for up to 105 jobs.
High Setpoint limits can be user programmed to emergency stop or top stop
the press
Counters record machine rating alarms and high and low setpoint alarms
Benefits
Provides on-line quality control by monitoring the force signature of every
part produced and stopping the press if any variation in the stamping process
due to dies, material, or press violates the signature limits established
for good parts
Storage and recall of limits and data window crankshaft angles provides
paperless record keeping for quick, automatic, consistent, setup to produce
good parts each time the die used.
Helps diagnose die, material, or press problems by graphically displaying
the force signatures so that signature changes indicate problem areas.
Die makers can use the signature to analyze and optimaize die performance
Helps protect presses from overload or poor load distribution
Protects dies that can withstand one bad hit due to process malfunction
