Title:
METHOD AND TOOL FOR THE 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
Document Type and Number:
WIPO Patent Application WO/2010/040791
Kind Code:
A3
Abstract:
The invention relates to a method for producing a connection between the neck area of a light metal cartridge, particularly an aluminum cartridge, and a plastic tank inserted therein, comprising a drawing process for forming a connection area and applying areas of the wall of the light metal cartridge against the plastic tank using a rotating main body (15) of a drawing tool (2), said main body supporting at least one profiled drawing roller (3) which can rotate about a rotational axis (5) for surrounding a tool working opening (1), wherein the drawing roller (3) lies against the outer surface of the light metal cartridge, and wherein the rotational axis (5) of the drawing roller (3) is arranged at a tool-internal end area of a lever (9) arranged transversely relative to the longitudinal axis (16) of the drawing tool (2). At the opposite tool-external end area of the lever, the lever is supported on the drawing tool (2) in a pivoting manner about a pivot axis (11) in a force controlled manner and so as to apply the drawing roller (3) against the outer surface of the light metal cartridge. The invention also relates to a drawing tool for carrying out said method.
