  • Apparatus and method for re-shaping brake cores
    Patent number: 6345427
    Abstract: A coining die apparatus for reshaping the backing plates of spent rotary drum brake cores in the production of remanufactured brake shoes comprises a lower die having a concave working surface configured to support a convex outer surface of a brake core backing plate to be coined. A moveable upper die includes axially-spaced outer die portions and a middle die portion between the outer portions having convex working surfaces. The middle and outer die portions are spaced laterally to accommodate a pair of mounting brackets extending from a convex inner surface of the backing plate. The middle die portion enters between the brackets when the dies are closed to strike and reshape a corresponding middle region of the backing plate between the brackets, while the outer die portions strike and reshape corresponding side portions of the mounting plate adjacent either side of the mounting brackets.
