Stamper Develops Cure for Die Roll
When a recent customer request-for-quote (RFQ) specified minimum die roll on pierced holes, engineers at metal- stamping company EBway Corp., Fort Lauderdale, FL, went to work developing a special stamping die to sat- isfy the request. The RFQ addressed a 0.409-in.-thick automotive part (left) and hex-head bolts used to fas- ten the part to a mating surface. Any out-of-tolerance die roll (or curved contouring on the side of the part oppo- site to the burr side) on the part’s pierced holes could cause the bolt heads to improperly seat as they were tightened. This could result in
a misaligned assembly.
EBway designed a special die to minimize die roll and satisfy the customer spec.
The technology used, which avoids any secondary machining or grinding by the cus- tomer, can be used on materials 0.060 to 0.50 in. thick.
