There is much more to die protection than just placing sensors in the tooling. Other opportunities exist to avert a possible die crash by monitoring motions and energy in the general press area surrounding the running die. Think about the various fluids and air streams counted on to make the stamping process possible. We tend not to think of these as part of the die-protection program, but nothing could be further from the truth. Here is a list of some items to think about that relate directly to the proper functioning of the die. Shakers and conveyor belts-These scrap- and part-removing press attachments are crucial to the proper functioning of the die. It is not rare for these devices to stop functioning and the scrap (or the parts) to build up into the die, causing a severe detonation of a die section (or more). Be vigilant in monitoring the shakers and conveyors. The motion of each must be sensed. If the shakers stop shaking or the conveyor stops moving, the die-protection system can stop the press and alert the operator to the nature of the problem.
