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.

Broad product range for tube manipulation

Kent Corporation, USA, offers a product line that includes equipment for liquid hydro and mechanical bellows forming machines, metal hose and end-finishing equipment, pipe expanders, tube/pipe swagers, tube/pipe benders, and hydraulic presses. The company serves applications including mechanical bellows forming, automotive tubular products, heavy wall

pipe bending, and forming for electrical power plants. They also provide for precision weld joint expanding, air- conditioning systems, heat exchangers, plumbing connections, metal furniture, and sports equipment.

› The PVM2000-MB mandrel bend monitor

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. OES Inc – Canada Fax : +1 519 652 3795
