摘要： A mandrel for use in tin box manufacturing apparatus is described. The mandrel is provided with a base component and a plurality of side wall components which are indirectly coupled to said base component such that the movement of said base component towards the center of said mandrel causes laterally outward displacement of said side wall components. The coupling is achieved by connecting a rod member to the base component which moves vertically within the mandrel when the base component moves and providing inclined cam surfaces on either side of said rod member against which cam followers provided on lateral actuating members are springingly biased. The cam surfaces of the rod member and the actuating members are ideally disposed within the mandrel in a plane parallel with the base component and at the mid point of the depth of the mandrel. On either side of the actuating members and optionally at the end thereof, secondary angled cam surfaces are provided against which cam followers coupled to the side wall components and optionally corner components of the mandrel are springingly biased. In use, the base component is forced inwardly of the mandrel, the rod member moves vertically upwardly as do the inclined cam surfaces thereon thus causing laterally outward motion of the actuating members and their cam surfaces, which in turn causes outward motion of the side wall components in a perpendicular direction, and outward motion of the optional corner components in a diagonal direction.
