WATCH: Double Blank Detection in the Transfer Stamping Process
Reliable Double-Sheet Detection
FULL ARTICLE Consider how much it costs to repair a die, replace the tooling or schedule a part sort, and then consider all of the related downtime. " " CLICK FOR Press-Line Part Sensing— Sooner is Better T he ability to detect blank and part presence, double sheets and more, prior to stamping, is a reliable money and time saver. That’s Brett Vance, business development manager of general metal forming industries for Prime Controls, Ket- tering, OH.
R eliable double-sheet detection prevents stamping-press-line mishaps that not only stymie productivity, but cause costly damage to tooling and equipment. Here’s how it works, along with some sensing and integration options for metal formers.
T he "oil suction effect" on metal sheets in a stack, be a troublesome issue. New long-range analog inductive proximity sensing technologies, with very dependable linearity, can reliably determine if more than one blank is present, which may be an option for many metal forming companies. whereby remnants of die lube can allow multiple blanks to stick together and potentially allow more than one blank to be picked up and inserted into a press, can
