Abstract
Description
Die Erfindung betrifft ein Werkzeug zum Innenhochdruckumformen insbesondere rohrförmiger Werkstücke nach dem Oberbegriff des ersten Patentanspruchs. Ein besonderes Problem besteht dabei in der Abdichtung der Enden der Rohre und Profile und in de Nachschieben der Endbereiche der rohrförmigen Werkstücke. Die Teilungsebene zwischen den Werkzeughälften setzt sich generell im Nachschiebebereich und Dichtbereich fort.The The invention relates to a tool for hydroforming in particular tubular workpieces after the preamble of the first claim. A special problem consists in the sealing of the ends of the tubes and profiles and in de Nachschieben the end portions of the tubular workpieces. The Division level between the tool halves is generally in the Nachschiebebereich and sealing area continues.
Aufgabe der Erfindung ist es, ein Werkzeug zum Innenhochdruckumformen zu entwickeln, mit welchem eine einfache und sichere Abdichtung des Nachschiebebereiches gewährleistet ist.task The invention is to a tool for hydroforming to develop, with which a simple and secure sealing of Nachschiebebereiches guaranteed is.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des ersten Patentanspruchs gelöst. Vorteilhafte Ausführungen ergeben sich aus den Unteransprüchen.These Task is according to the invention with the characterizing features of the first claim solved. advantageous versions emerge from the dependent claims.
Das Werkzeug zum Innenhochdruckumformen insbesondere rohrförmiger Werkstücke weist zwei geteilte Werkzeughälften auf, welche im geschlossenen Zustand eine Gravur entsprechend des herzustellenden Bauteiles aufweisen und besitzt mindestens eine Dicht- und Nachschiebeelement zum Nachschieben und Abdichten des rohrförmigen Werkstückes. Erfindungsgemäß weist eine erste Werkzeughälfte im Bereich des Dicht- und Nachschiebeelementes eine, das Dicht- und Nachschiebeelement aufnehmende, Bohrung auf, deren Längsachse mit der Längsachse des Werkstücks fluchtet, wobei die Teilung der Werkzeughälften einen ersten Teilungsabschnitt aufweist, der im Bereich der Gravur in der Werkstücklängsachse liegt und einen zweiten Teilungsabschnitt aufweist, der den Bereich der Bohrung tunnelartig im Bereich des Dicht- und Nachschiebeelementes überbrückt.The Tool for hydroforming particular tubular workpieces has two divided tool halves on, which in the closed state an engraving according to the produced Have components and has at least one sealing and Nachschiebeelement for feeding and sealing the tubular workpiece. According to the invention a first tool half in the area of the sealing and feeding element, the sealing and Nachschiebeelement receiving, bore on, the longitudinal axis with the longitudinal axis of the workpiece is aligned, wherein the division of the tool halves a first division section having, in the field of engraving in the workpiece longitudinal axis is located and has a second division section, which is the area the hole tunnel-like bridged in the region of the sealing and Nachschiebeelementes.
Nach der Bohrung in Richtung zur Gravur ist ein dritter Teilungsabschnitt zwischen beiden Werkzeughälften vorhanden, der den ersten und den zweiten Teilungsabschnitt miteinander verbindet. Dieser dritte Teilungsabschnitt liegt bevorzugt rechtwinklig zum ersten und zweite Teilungsabschnitt.To the hole in the direction of the engraving is a third division section between the two halves of the mold present, the first and the second division section with each other combines. This third division section is preferably at right angles to first and second division section.
Um die erforderliche Stabilität zu gewährleisten, muss die ersten Werkzeughälfte im Bereich längs der Bohrung bis zum zweiten Teilbereich eine bestimmte Mindestwandstärke aufweisen.Around the required stability to ensure, must be the first tool half in the area along the bore to the second portion have a certain minimum wall thickness.
Zwischen beiden Werkzeughälften ist im Bereich des ersten und des zweiten Teilungsanschnitts eine Dichtschnur und zwischen dem Außendurchmesser des Dicht- und Nachschiebeelementes und dem Innendurchmesser der Bohrung eine Dichtung angeordnet.Between both tool halves is in the range of the first and second Teilungsanschnitts a Sealing cord and between the outer diameter of the sealing and Nachschiebeelementes and the inner diameter of Bore a seal arranged.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels und zugehöriger Zeichnungen näher erläutert. Es zeigen:The Invention will be described below with reference to an embodiment and associated drawings explained in more detail. It demonstrate:
