OmniLink TSM - Tonnage and Signature Analysis Module

OmniLink TSM 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 (click to enlarge)   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 (click to enlarge) 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.


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


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
