Our customer needed to manufacture gum drop shaped tabs with
½” holes using their Marvel MSIW60D ironworker. Our engineering team determined
a two-step operation would be necessary to produce these tabs.
The first operation included manufacturing gum drop shaped
tooling to fit the oversize attachment. The punch was machined with a flat face
and we used .028” clearance to ensure each tab would be free of any
distortions. Lastly, it was critical to machine a 1/4“x1/8” keyway on the punch
and whistle notches on the die to provide proper alignment during the punching
proce ss.
To begin the second operation, we replaced the oversize
attachment with the standard attachment for punching the ½” round holes. This
is an easy switch and tooling is more cost effective. We designed a die with 3
alignment pins to guarantee the hole would be punched in the same position on
each tab.
The customer will weld these onto their product and utilize
the round holes for bolts.
