Description
Verfahren zur Herstellung von Holzbearbeitungasägen. Zur Herstellung vergüteter Holzbearbei- tungssägen, wie Gatter-, Kreis- und Band sägen, sind unlegierte oder niedriglegierte Stähle mit 0,50 bis 1,00% Kohlenstoff üblich. Für naturharte Sägen zur Holzbearbeitung wurden Stähle mit 0,
30 bis 0,60% Kohlen- stoff, 0,10 bis 0,50% Mangan, 0,40 bis 2,00% Silizium, 0,50 bis 3,00% Wolfram und 0,50 bis 1,
50% Chrom vorgeschlagen, in welchen das Wolfram ganz oder teilweise durch Molyb- dän ersetzt und zur Erhöhung der Leistungs fähigkeit Vanadium zugesetzt sein kann. Ein weiterer Vorschlag ging dahin, Sägeketten so wie Band-, Gatter- und Kreissägen zur Holz bearbeitung aus bis zur Grenze der Feilbarkeit vergüteten Federstählen herzustellen.
Die Erfindung bezweckt, die Leistungs fähigkeit von Sägen zur Holzbearbeitung zu erhöhen und betrifft ein Verfahren zur Her stellung von Holzbearbeitungssägen, welches dadurch gekennzeichnet ist, dass diese Sägen aus einem Stahl mit 0,80 bis 1,50% Kohlen- stoff und 0,90 bis 3,
00% mindestens eines Me- talles der Gruppe VIa des periodischen Sy stems der Elemente mit einem Atomgewicht zwischen 90 und 190 hergestellt werden. Der Stahl enthält vorzugsweise Wolfram in den angegebenen Grenzen, das jedoch ganz oder teilweise durch Molybdän ersetzt sein kann. Ausserdem kann dieser Stahl zur Verbesserung seiner Eigenschaften, z.
B. der Zähigkeit oder Schnittleistung, noch 0,10 bis 3,00% Chrom, 0,10 bis 3,00% Vanadium, einzeln oder ge- meinsam, enthalten.
Es hat sich wider Erwarten gezeigt, dass diese Stähle allen Anforderungen entsprechen, die an sie bei ihrer Verarbeitung zu Holzbear- beitungssägen gestellt werden, darüber hinaus aber noch eine bedeutend höhere Schnittlei tung als bekannte Holzsägenstähle aufweisen.
So hatten zum Beispiel vergütete Gatter- sägen aus einem Stahl mit etwa 1,10% C, 0,30% Mn, 0,15% Si, 1,20% W, 0,20% Cr und 0,
12% V gegenüber bekannten vergüteten Gattersägen unter gleichen Versuchsbedingun- . gen eine dreifache Schnittleistung ergeben.
Process for the manufacture of woodworking saws. Unalloyed or low-alloy steels with 0.50 to 1.00% carbon are common for the manufacture of tempered woodworking saws such as frame saws, circular saws and band saws. For naturally hard saws for woodworking, steels with 0,
30 to 0.60% carbon, 0.10 to 0.50% manganese, 0.40 to 2.00% silicon, 0.50 to 3.00% tungsten and 0.50 to 1,
Proposed 50% chromium, in which the tungsten completely or partially replaced by molybdenum and vanadium can be added to increase the performance. Another suggestion was to manufacture saw chains such as band, frame and circular saws for wood processing from spring steels tempered to the limit of filability.
The invention aims to increase the performance of saws for woodworking and relates to a method for producing woodworking saws, which is characterized in that these saws are made of a steel with 0.80 to 1.50% carbon and 0.90 to 3,
00% of at least one metal from group VIa of the periodic system of the elements with an atomic weight between 90 and 190 can be produced. The steel preferably contains tungsten within the specified limits, which, however, can be completely or partially replaced by molybdenum. In addition, this steel can be used to improve its properties, e.g.
B. the toughness or cutting performance, still contain 0.10 to 3.00% chromium, 0.10 to 3.00% vanadium, individually or together.
Contrary to expectations, it has been shown that these steels meet all the requirements that are placed on them when they are processed into woodworking saws, but that they also have a significantly higher cutting performance than known wood saw steels.
For example, heat-treated frame saws made of a steel with about 1.10% C, 0.30% Mn, 0.15% Si, 1.20% W, 0.20% Cr and 0,
12% V compared to known tempered frame saws under the same test conditions. gen a triple cutting performance.
