Serapid’s RollBeam telescopic rigid-chain actuators combine with a gear motor to form a push-pull system to power die movement from the die cart to the press. One die-cart position stages the next die to run while the second die cart accepts the previous die as it leaves the press.

70-Percent Faster,50-Times More Precise

Die-change time now averages 60 min. from last part to first part, including disconnecting and reconnecting lubrication lines and changing out shaker-tray scrap conveyors. And, there’s no longer any need to fuss with the blank feeder or reprogram the robots. From the cell control station, a press operator triggers the completely automated die-change cycle: part-palletizing carts (on an embedded floor rail) and the robots move out of the as the drawbridge indexes down into place between the die cart and the press; the old die rolls out and new die rolls in; the drawbridge raises and the line is ready for action.

What about locating accuracy? The slow, controlled movement of rolling the die onto the bolster, rather than bumping it into position as it used to, allows the machined V-groove to more precisely mate to the locator in the bolster. To take full advantage of the precise, controlled push-pull action, West had the die shop machine sharper-angled V grooves in the dies.

“In Serapid’s initial quote,” West says, “they specified die-position repeatability of ±1⁄8 in. In reality, we’re seeing significantly more precise location than that, more like ±0.010 in.” MF
