Abstract
Description
Die
vorliegende Erfindung betrifft ein Verfahren, wie es im Oberbegriff
von Anspruch 1 definiert ist (siehe beispielsweise
Dieser Typ der Vorrichtung ist vorbekannt in einer Maschine, die von Witzig und Frank GmbH hergestellt wurde (Zeichnung E3 in der Amtsakte dieses Patents). In dieser Vorrichtung wird ein Kalibrierdorn verwendet, um eine einen Kragen formende Kugel zurückzudrücken und um den Kragen zu vergrößern. Mit dieser Vorrichtung ist es aber nicht möglich, die verschiedenen Zurückspringeffekte des Materials in verschiedenen Richtungen des Kragens zu kompensieren oder zu korrigieren.This Type of device is previously known in a machine that is of Witzig and Frank GmbH (drawing E3 in the official file of this patent). In this device, a Kalibrierdorn is used to a to push back a collar forming ball and to enlarge the collar. With However, this device is not possible, the various recoil effects of the material in different directions of the collar to compensate or correct.
Wenn ein rohrförmiges Metallgehäuse oder Mantel durch das Aufweiten des Gehäusematerials mit einer Abzweigung, einem zylinderförmigen Kragen oder einem Hals versehen wird, dann wird seine endgültige Größe durch die Elastizität des Rohres und die inneren Restspannungen des Materials bestimmt. In der Regel ist die Kragengröße D2 in der Richtung quer zum Rohr geringer als in der Längsrichtung D1. Darüber hinaus ist bei der Mehrzahl der relevanten Materialien wie zum Beispiel rostfreiem Stahl die Kragengröße in der Durchmesserrichtung geringer als eine Abmessung D2' des für die Ausbildung des Kragens benutzten Werkzeugs.When a tubular metal casing or jacket is provided with a branch, cylindrical collar or neck by the expansion of the casing material, its final size is determined by the elasticity of the tube and the internal residual stresses of the material. As a rule, the collar size D 2 in the direction transverse to the tube is less than in the longitudinal direction D 1 . Moreover, in the majority of relevant materials, such as stainless steel, the collar size in the diametric direction is less than a dimension D 2 'of the tool used to form the collar.
