Description

Zieheisen und ähnliche Werkzeuge Für Zieheisen .und ähnliche Werkzeuge, die gegen. Abnutzung besonders Widerstandsfähig und gleichzeitig trotz hoher Festigkeit gut bearbeitbar sein sollen, hat man bisher noch keine geeignete Legierung gefunden. Es hat sich nun gezeigt, daß ein Stahl folgender Zusammensetzung - C == r;4 bis 2,5, Cr ^ To bis 2o, Cu:- o,5 bis bis 4,5 04 für derartige Zwecke in ganz hervorragendem Maße -entspricht. Diese Legierung wurde für diese Werkzeuge erprobt, wobei festgestellt werden konnte, daß sie sich bei etwa 16o kg/mm2 Festigkeit noch gut bohren läßt, während dies bei den üblichen Zieheisenstählen bei einer Festigkeit von über 130 kg/mm' schon außerordentlich schwierig ist. Neben der größeren Härte ergab sich aber auch der Vorteil, daß die Zieheisenkanäle viel glatter und sauberer herstellbar sind. Ferner konnte festgestellt werden, daß solche Zieheisen nicht so leicht zum Sperrgehen neigen, wodurch auch das Ziehgut eine bessere Oberflächenbeschaffenheit erhält.Drawing dies and similar tools For drawing dies and similar tools that are used against. A suitable alloy has not yet been found to be particularly resistant to wear and tear and, at the same time, to be easy to machine despite high strength. It has now been shown that a steel of the following composition - C == r; 4 to 2.5, Cr ^ To to 2o, Cu: - 0.5 to 4.5 04 for such purposes - corresponds to a very good degree . This alloy was tested for these tools, and it was found that they can be at about 16o kg / mm2 still drilling well while this is extremely difficult in conventional threading die steels at a strength of about 1 30 kg / mm 'already. In addition to the greater hardness, there was also the advantage that the drawing iron channels can be produced much smoother and cleaner. Furthermore, it was found that such drawing dies do not tend to jam so easily, which also gives the drawn material a better surface quality.

Es ist zwar bekanntgeworden, Chrom-Kupfer-Legierungen für Gegenstände, die Beständigkeit gegen Rost erfordern, zu verwenden'. Es ist weiter auch vorgeschlagen worden, Chrom-Kohlenstoff-Stähle mit geringen Zusätzen anderer Elemente für Werkzeugstähle zu verwenden; die Eignung der in der Erfindung beschriebenen Chrom-Kupfer-Legierung für dem Verschleiß ausgesetzte Gegenstände sowie die gute Bearbeitbarkeit eines solchen Stahles wurde aber bisher noch nicht erkannt.It has become known to use chrome-copper alloys for objects which require resistance to rust to 'use'. It is also suggested further chrome-carbon steels with small additions of other elements for tool steels to use; the suitability of the chromium-copper alloy described in the invention for objects exposed to wear as well as the good machinability of a such steel has not yet been recognized.
