Abstract

The die is made from a multicomponent aluminum bronze. An Independent claim is made for a process for producing the calibrating die by scanning the functional metal surface (1) with a carbon dioxide or Nd-YAD (solid state) laser beam (2) and overlapping the scanning paths. The beam remelts the surface to a depth of 0.2-1.0mm and reacts with process gases, e.g. nitrogen, oxygen or carbon dioxide.

Description

Die Erfindung betrifft ein hochverschleißfestes Kalibrierwerkzeug nach dem Oberbegriff des Patentanspruches 1.The invention relates to a highly wear-resistant Calibration tool according to the preamble of the claim 1.

Es ist bekannt, Kalibrierwerkzeuge für die Herstellung von Kunststoffprofilen für Fenster, Türen und andere stabförmige Bauteile einzusetzen. Das Kalibrierwerkzeug besteht aus einem Trägerwerkzeug mit auf ihm montierten, beschichteten Messing-, Kupfer- und/oder Stahlkernen. Die Kalibrierwerkzeuge werden vorrangig durch hohe Temperaturen an der Eintrittskante und durch das Gleiten der abkühlenden Profilteile in der Formstrecke beansprucht. Bekanntermaßen sind gegenwärtig Kalibrierwerkzeuge zur Verbesserung der Verschleißbeständigkeit und zur Erhöhung der Lebensdauer auf den Funktionsflächen häufig mit einer Schicht aus Chromnitrid versehen. Um jedoch die Chromnitridschicht in hoher Qualität und mit guter Bindung zum Trägermaterial mit Hilfe des PVD-Verfahrens auf den Trägerwerkstoff zu bringen, bedarf es einer Zwischenschicht aus phosphorlegiertem Nickel. Der Härtezuwachs findet hierbei in einem kleinen Dickenbereich von 3-5 µm statt. Die Gefahr des Durchbrechens der Härteschicht in das weiche Grundmaterial ist bei den auftretenden hohen Flächenpressungen gegeben.It is known to manufacture calibration tools Plastic profiles for windows, doors and others use rod-shaped components. The calibration tool consists of a carrier tool with mounted on it coated brass, copper and / or steel cores. The Calibration tools are primarily caused by high temperatures at the leading edge and by sliding the cooling ones Stressed profile parts in the molding section. As is known are currently calibration tools to improve the Resistance to wear and to increase the service life often with one layer on the functional surfaces Chromium nitride. However, in order to remove the chromium nitride layer in high quality and with good bond to the carrier material With the help of the PVD process towards the carrier material bring, an intermediate layer is required phosphorus alloyed nickel. The increase in hardness takes place here in a small thickness range of 3-5 µm. The Risk of breaking through the hardness layer in the soft Base material is at the occurring high Given surface pressures.

Es ist bekannt, die Randschichten von Mehrstoffaluminiumbronzen durch Laserstrahlumschmelzen zu härten, u. a. beschrieben in METALL Heft 4 1992. Die Oberfläche der Mehrstoffaluminiumbronze wird mit einem Laserstrahl hoher Leistung derart bearbeitet, daß lokal eine umgeschmolzene Schicht erzeugt wird, der während des Aufschmelzens auch zumindest ein Reaktionspartner zugefügt werden kann. Der Laserstrahl kann vorzugsweise mit einem Nd-YAG-Laser oder mit einem CO2-Laser erzeugt werden. Der Erfindung liegt die Aufgabe zu Grunde, ein Kalibrierwerkzeug zu beschreiben, dessen Funktionsflächen über ein widerstandsfähiges Verschleißsystem aus einer oder mehreren Schichten verfügt. Außerdem soll ein neues Verfahren vorgeschlagen werden, das ein anforderungsgerechtes Schichthärten der Funktionsflächen ermöglicht.It is known the outer layers of Multi-component aluminum bronzes by laser beam remelting harden, u. a. described in METALL No. 4 1992. Die The surface of the multi-component aluminum bronze is covered with a High power laser beam processed so that local a remelted layer is created, which during the Melting also added at least one reaction partner  can be. The laser beam can preferably with a Nd-YAG laser or can be generated with a CO2 laser. The invention is based on the object Describe the calibration tool, its functional surfaces via a resistant wear system from one or several Layers. In addition, a new procedure is said be proposed, which is a requirement Layer hardening of the functional surfaces enables.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Kalibrierwerkzeuge aus einer Mehrstoffaluminiumbronze bestehen. Sie ersetzen die bisher verwendeten Kalibrierwerkzeug aus Messing, Kupfer und/oder Stahl. Weitere Vorteile bestehen darin, daß die Funktionsflächen rasterförmig gehärtet sind. Das Raster kann wahlweise grob oder fein sein und ermöglicht somit eine belastungsgerechte Ausführung der Funktionsflächen. Durch Überlappung der Spuren kann eine flächendeckend bearbeitete Funktionsfläche entstehen. Als weiterer wesentlicher Vorteil ist zu nennen, daß sich entsprechend des gewählten Rasters entweder auf der gesamten Funktionsfläche oder nur auf Teilen derselben umgeschmolzene und nicht umgeschmolzene Bereiche abwechseln.According to the invention the object is achieved in that the Calibration tools made of a multi-component aluminum bronze consist. They replace the previously used Calibration tool made of brass, copper and / or steel. Further advantages are that the functional surfaces are hardened in a grid pattern. The grid can optionally be rough or be fine and thus enables a load-oriented Execution of the functional areas. By overlapping the A fully processed functional surface can leave traces arise. Another major advantage is that according to the chosen grid either the entire functional area or only parts of it remelted and unmelted areas alternate.

Ausführungsbeispiele sind in der Fig. 1 beschrieben. In beiden Abbildungen a) und b) stellt (1) die Funktionsfläche des aus Mehrstoffaluminiumbronze bestehenden Kalibrierwerkzeuges dar.Exemplary embodiments are described in FIG. 1. In both figures a) and b) ( 1 ) represents the functional surface of the calibration tool made of multi-material aluminum bronze.

Im Fallbeispiel a) wird der Laser (3) in linienförmigen Bahnen über die Funktionsfläche (1) bewegt, wobei aus den einzelnen Spuren (3) das Raster entsteht. Die Spuren überlappen sich, so daß eine flächige Umschmelzung der Funktionsfläche (1) erfolgt. In case a), the laser ( 3 ) is moved in linear paths over the functional surface ( 1 ), the grid being created from the individual tracks ( 3 ). The traces overlap so that the functional surface ( 1 ) is remelted.

Im abgewandelten Ausführungsbeispiel b) erfolgt die Abrasterung in Bahnen, die sich nicht überlappen. So entsteht ein Muster von umgeschmolzenen Spuren (4), die sich mit nicht umgeschmolzenen Bereichen abwechseln. Die Anordnung der umgeschmolzenen Spuren und der nicht umgeschmolzenen Bereiche wird der jeweilig zu erwartenden Beanspruchung der Funktionsfläche des Kalibrierwerkzeuges angepaßt.In the modified exemplary embodiment b), the scanning takes place in paths which do not overlap. This creates a pattern of remelted tracks ( 4 ) that alternate with unmelted areas. The arrangement of the remelted tracks and the unmelted areas is adapted to the expected stress on the functional surface of the calibration tool.
