Abstract (en)

A mandrel for bending of simple construction and sufficient rigidity is obtained. The mandrel comprises a plurality of plugs (12). Each plug is provided with a spherical outer peripheral surface. A fulcrum pin (16) is fitted through the plug. The first and second link members (18,20,22) are rotatably attached to the fulcrum pins of the neighboring plugs so as to connect the neighboring plugs. The plug is also provided with a spherical depression which the adjoining plug can enter during the bending. The plugs are connected to the shank (14) via the second link members. <IMAGE>
