Leaf spring cambering apparatus

摘要

Disclosed is a cambering apparatus for imparting a predetermined camber to a leaf spring blank loaded between a pair of dies opposing vertically to each other by bringing the dies closer relative to each other; the apparatus comprising an upper variable die and a lower variable die; the upper variable die essentially consisting of a multiplicity of upper supporting members disposed on upper guide members to be slidable in the longitudinal direction thereof; and a multiplicity of upper shaping fingers fitted descendably in U-shaped grooves defined on the upper supporting members, respectively; whereas the lower variable die consisting essentially of a multiplicity of lower supporting members disposed on lower guide members to be slidable in the longitudinal direction thereof; and a multiplicity of lower shaping fingers fitted ascendably in U-shaped grooves defined in the lower supporting members, respectively; wherein the shaping fingers are ascended or descended to be positioned onto the supporting members respectively by a die shaping device disposed in the main body frame so as to form a predetermined die profile by each of the upper and lower groups of shaping fingers along the opposing ends of the groups of shaping fingers.
