Description
Verwendung eines Stahles für dynamisch beanspruchte Werkzeuge Die Erfindung betrifft die Verwendung eines Stahles für Werkzeuge, die dynamisch beansprucht werden. Solche Werkzeuge sind beispielsweise Döpper, Pressluftmeissel, Maschinenschraubenzieher und dergleichen sowie in gewisser Weise auch Be- steckstanzen und ähnliche Kaltschlagmatrizen. Solche dynamisch,
also auf Schlag beanspruchte Werkzeuge werden bei hohen Anforderungen an die Leistung vornehmlich aus Chrom-Wolfram-Silizium- oder Chrom-Silizium-Vanadin-Stählen mit Kohlenstoff gehalten von 0,35-0,6014, Chromgehalten von 1,0 bis 1,50/a, Wolframgehalten von angenähert 211/o, Siliziumgehalten von 1,0 bis 2,011/a und Vanadin- gehalten von 0,1 bis 0,311/o hergestellt.
Daneben fin den Chrom-Nickelstähle mit Chromgehalten von 0,5 bis 1,5111a und Nickelgehalten von 1,5 bis 4,5% sowie Silizium-Molybdänstähle mit 0,3 bis 0,6% Molybdän und 1,5 bis 2,
011/o Silizium Verwendung. Diese als Dauerstähle bekannten Stahlsorten werden mit Härten von max. 58 Rc eingesetzt und zeigen aus diesem Grunde neben den für Dauerschlagbean- spruchung ausreichenden Zähigkeitseigenschaften eine Druckbelastbarkeit in der Grössenordnung von 200 bis 230 kglmm2. Stähle mit höherer Druckbelast barkeit und ausreichenden Zähigkeitseigenschaften für eine Dauerschlagbeanspruchung standen bisher nicht zur Verfügung.
Zweck der Erfindung ist es, diese Lücke zu schliessen, und diese Aufgabe wird erfindungsgemäss gelöst durch die Verwendung eines Stahles mit 0,65 bis 0,8511/o Kohlenstoff 1,20 bis 2,50% Chrom 0,30 bis 1,00% Nickel 0,30 bis 1,50% Molybdän 0,50 bis 2,
50% Silizium Ein Werkstoff dieser Zusammensetzung ist zur Herstellung von Werkzeugen geeignet, die dynamisch beansprucht werden und Druckbelastungen von 200 bis 280 kg/mm-2 ohne plastische Verformung und bleibende Schädigung aushalten können.
Stähle dieser Legierungszusammensetzung sind an sich bekannt, wurden aber bisher nicht für den gekennzeichneten Zweck verwendet.
Der Stahl kann zusätzlich noch 0,2 bis 1,0% Wolfram und 0,1 bis 0,6% Vanadin einzeln oder gemeinsam enthalten. Hierdurch werden insbeson dere die Feinkörnigkeit und der Verschleisswider stand der einbaufertigen Werkzeuge günstig beein flusst.
Besonders bewährt hat sich ein Stahl mit 0,70 bis 0,8011/o Kohlenstoff 1,40 bis 1,6011/o Chrom 0,40 bis 0,600/a Nickel 0,60 bis 0,8011/o Molybdän 0,30 bis 0,40-11/o Wolfram 1,40 bis 1,600/a Silizium und Rest Eisen Ein solcher Stahl hat eine spezifische Druck belastbarkeit von 260 bis 280 kg/nun2, ohne sich hierbei plastisch zu verformen.
Die Zähigkeit dieses Stahles entspricht bei der zu dieser spez. Druck belastbarkeit notwendigen Einbauhärte von 60 bis 61 Rc praktisch den Zähigkeitswerten, die bei den bisher für Dauerschlagbeanspruchung verwendeten Chrom Wolfram-Silizium-Stählen bei Einbauhärten von 58 Rc gefunden werden.
Praktische Versuche mit Pressluftmeisseln zum Putzen von Platinen ergaben, dass die Standzeit von Putzmeisseln aus diesem Stahl die Standzeit der bisher verwendeten Meissel aus Chrom-Wolfram-Sili- zium-Dauerstahl um mindestens 25 % übertraf. Diese erhebliche Mehrleistung ist auf die stark erhöhte spezifische Belastbarkeit zurückzuführen, die von den bisher verwendeten Stählen bei weitem nicht er reicht wird.
Use of a steel for dynamically stressed tools The invention relates to the use of a steel for tools that are dynamically stressed. Such tools are, for example, anvil, compressed air chisel, machine screwdriver and the like and, to a certain extent, also cutlery punches and similar cold impact dies. Such dynamic,
In other words, tools that are exposed to impact are made of chrome-tungsten-silicon or chrome-silicon-vanadium steels with carbon of 0.35-0.6014, chrome contents of 1.0 to 1.50 / a, tungsten contents of approximately 211 / o, silicon contents of 1.0 to 2.011 / a and vanadium contents of 0.1 to 0.311 / o.
In addition, there are chromium-nickel steels with chromium contents of 0.5 to 1.5111a and nickel contents of 1.5 to 4.5% and silicon-molybdenum steels with 0.3 to 0.6% molybdenum and 1.5 to 2,
011 / o use of silicon. These types of steel, known as permanent steels, are produced with a hardness of max. 58 Rc are used and for this reason show, in addition to the toughness properties sufficient for continuous impact stress, a compressive strength in the order of magnitude of 200 to 230 kgmm2. Steels with higher compressive strength and sufficient toughness properties for continuous impact stress have not been available until now.
The purpose of the invention is to close this gap, and this object is achieved according to the invention by using a steel with 0.65 to 0.8511 / o carbon 1.20 to 2.50% chromium 0.30 to 1.00% Nickel 0.30 to 1.50% molybdenum 0.50 to 2,
50% silicon A material of this composition is suitable for the production of tools that are dynamically stressed and can withstand pressure loads of 200 to 280 kg / mm-2 without plastic deformation and permanent damage.
Steels of this alloy composition are known per se, but have so far not been used for the stated purpose.
The steel can also contain 0.2 to 1.0% tungsten and 0.1 to 0.6% vanadium individually or together. In particular, this has a favorable effect on the fine-grain size and wear resistance of the ready-to-install tools.
A steel with 0.70 to 0.8011 / o carbon 1.40 to 1.6011 / o chromium 0.40 to 0.600 / o nickel 0.60 to 0.8011 / o molybdenum 0.30 to 0 has proven particularly useful , 40-11 / o tungsten 1.40 to 1.600 / a silicon and the remainder iron Such a steel has a specific compressive strength of 260 to 280 kg / nun2 without undergoing plastic deformation.
The toughness of this steel corresponds to this spec. The required installation hardness of 60 to 61 Rc.
Practical tests with compressed air chisels for cleaning blanks showed that the service life of cleaning chisels made from this steel exceeded the service life of the chisels made from chrome-tungsten-silicon permanent steel by at least 25%. This considerable increase in performance is due to the greatly increased specific load capacity, which is far from being achieved by the steels used so far.
