Title:
GUIDED KEEPER ASSEMBLY AND METHOD FOR METAL FORMING DIES
Document Type and Number:
WIPO Patent Application WO/2012/115901
Kind Code:
A3
Abstract:
A guided keeper assembly and related method includes a cylindrical base that mounts to a die member using a multi-piece, interlocking flange. The flanges have outer fastener holes and inner arcuate walls that matingly engage a complimentary profile on the outer surface of the base to axially interconnect the same. The flanges also have male and female end connectors which snap lock together around the base in an assembled condition. Mounting screws pass through the fastener holes in the flanges and are anchored in the die member to securely retain the guided keeper assembly in place. A retainer ring is mounted in an associated groove in the base over the heads of the screws to prevent unintentional unfastening of the screws from the die member.
