Abstract
A holding device for a cage for roll bodies of longitudinal leaders on pillars of a tool, in particular a blanking or punching die or a mould, the tool consisting of a plurality of assembled plates, and having at least a first part and a second part. The holding device comprises a holding part which includes a hollow cylindrical rod, held displaceably in a longitudinal bore made on the free end of each pillar. Said rod is provided on its face with a disk projecting beyond the circumference of the pillar. Also inserted into the longitudinal bore is a screw. Provided on the shank of said screw is an elastic element over which an annular element, inserted into the hollow cylindrical rod, is pushed when the holding part is in pushed-in position. The elastic element holds the annular element in this position in a firmly clamping fashion. The disk in this position prevents the cage from being able to move out beyond the end of the pillar and be damaged, in particular when the tool is tilted with respect to the pillars.
