Abstract: The provided process creates a fully flanged interlocked bushing by feeding a metal strip into a stamping assembly having a plurality of tool stations. The stations blank a workpiece from the metal strip, and trim the workpiece's two opposing ends forming a triangular shaped tab and a puzzle locking feature on either end. The workpiece is then formed into an annular shape, wherein the triangular shaped tabs are overlapped as the opposing ends are abutted and interlocked. A flange is then imparted into the side wall of the workpiece relieving the tab's overlapping condition, causing the tabs to abut one another and become co-planar with the flange. This creating a fully flanged part with a tightly fitted parting line. This invention also includes products formed by the aforementioned process.
