A swing-down bolster extension enables easy retrieval by die-transport vehicles.
“Obviously, the quicker we can get the die running,” Gray continues, “the better, as we’re always watching the OEE (overall equipment effectiveness) and looking to reduce lead times.”
Clamping Down on Safety
Responsible for helping Stanley meet its QDC needs is Dave Defrees, application engineer for Press Automation, distributor of Pacesetter systems, and 34-yr. partner with Stanley.
“Safety is an important factor when it comes to changing

dies,” says Defrees, citing the system’s clamping technology as an example. “With this system, hydraulic pressure is used to stretch the bolt. Then it’s screwed tight with air pressure maintained on the bolt. This is safer than a straight-up hydraulic system where, if the hydraulic pressure fails, you lose the clamp.
“As for the lift station,” he continues, “the bolster extension allows the operator to put the die extension on while standing 2 ft. from the press, resulting in less risk of damaging the press when setting the dies or the plate that attaches to the bottom of the dies. Another safety feature: a pressure switch that pre- vents clamping of dies while the lifter is raised. The lifter must be mechanically lowered before dies can be clamped.”
Says Gray, “Just like we’re always looking for ways to reduce setup time, so, too, we are always looking for safer ways for operators to stage the dies in the press.” MF
