New bending process monitor to protect equipment

摘要

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.
