Verfahren und Vorrichtung zur dichten Befestigung eines Schlauchstückes aus elastomerem Werkstoff an einem Anschlussteil

摘要

The invention relates to a method for tightly attaching a piece of flexible tubing of an elastomeric material to a connecting part, especially for attaching air bellows for pneumatic springs to a connecting part with a clamping ring, which is radially pressed using a pressing tool. The force-displacement characteristic line (16) of the pressing tool is recorded while the clamping ring is being radially pressed, in order to carry out the method. This force-displacement characteristic line (16) is used to determine the lost force that is required in the pressing tool for the plastic deformation of the clamping ring and for overcoming the inner friction of the pressing tool. This lost force is used for adjusting the additional force resulting from the pressing tool being moved together in such a way that it corresponds to a predetermined force between the piece of flexible tubing and the connecting part. The invention also relates to a pressing tool for carrying out this method.
