CYLINDRICAL DEFORMATION OF AN AL SLEEVE TO THE CORE DIMENSION OF THE INTERNAL PLASTIC CLOSURE, AS PREPARATION FOR A DIFFUSION-PROOF PRESS CONNECTION WITHIN THE TWO COMPONENTS

摘要

In a method of producing a connection between the neck area of a light metalcartridge,particularly an aluminium cartridge, and a plastic container inserted therein,by adrawing process that forms a connection area and applies areas of the wall ofthe lightmetal cartridge against the plastic container using a rotating main body (15)of adrawing tool (2), said main body supporting at least one profiled drawingroller (3)which can rotate about a rotation axis (5) in order to delimit a tool workingopening (1),wherein the drawing roller (3) lies against the outer surface of the lightmetal cartridge,the rotation axis (5) of the drawing roller (3) is arranged at a tool-internalend area of alever (9) arranged transversely relative to the longitudinal axis (16) of thedrawing tool(2), said lever being supported at its opposite tool-external end area on thedrawingtool (2) so as to be pivotable about a pivot axis (11) in a force-controlledmanner andso as to apply the drawing roller (3) against the outer surface of the lightmetalcartridge.
