New bending process monitor
to protect equipment
OES Inc, Canada, has launched a new
process variation monitoring system for
mandrel bending applications. The PVM2000-
MB mandrel bend monitor provides dynamic
in-process monitoring of the bending process
to detect excessive tension or compression
on the mandrel rod that can cause excess
wear or equipment damage.
Detection of excessive pull force on
the mandrel rod during the bend cycle
indicates process variation that may lead
to mandrel failure. This can result from loss
of lubrication, weld seam imperfections,
galling of the mandrel, wiper die wear,
or the poor adjustment of the mandrel
position. The system can also detect
excessive compression force during
mandrel advancement to prevent bending
the mandrel rod if there is an insertion jam.
Mr Michael Reeve, VP of market
development for OES, commented,
“The initial design of this system was for
detection of mandrel failure. The new
PVM2000-MB goes well beyond that by
detecting process variations that can
lead to equipment problems. Users of the
monitor find that it makes them aware of
potential problems before they occur.”
The PVM2000-MB provides two levels of
alert to process variations, and offers both
audible and visual alarm options to indicate
fault conditions to the machine operator.
By integrating the fail output to machine
control, the bend cycle can be stopped
before damage occurs.
A touch screen interface provides monitoring,
configuration and threshold adjustment.
Assisted by the BendView companion
software, each bend can be logged onto a
computer for analysis and traceability.
