Description

Einrichtung zum Anlassen und dergl. von Werkstücken, insbesondere Kleinteilen Die Erfindung betrifft ein Verfahren zum Härten, Anlassen und dergl. von Werkstücken, insbesondere Kleinteilen, wie z. B. Rasierklingen, Kleinteile von Meßinstrumenten (Taster von Meßuhren), Sägeblättern, Teile von Schreibmaschinen, kleine Zahnräder, Kleinstwerkzeuge, Lineale, Abkantwerkzeuge, kleine Schnittwerkzeuge und dergl.Device for tempering and the like of workpieces, in particular Small parts The invention relates to a method for hardening, tempering and the like. of workpieces, especially small parts, such. B. razor blades, small parts of Measuring instruments (dial gauge probes), saw blades, parts of typewriters, small gears, small tools, rulers, folding tools, small cutting tools and the like

Als Wärmequellen werden beim Härten derartiger Kleinteile bisher im wesentlichen benutzt: Elektrisch beheizte Öfen, Kammeröfen mit geschlossenem Glührahmen, Kammeröfen mit offenem Glührahmen, Salzbad-Tiegelöfen und Bleibäder.As a heat source when hardening such small parts are so far in Mainly used: Electrically heated furnaces, chamber furnaces with closed annealing frames, Chamber furnaces with an open annealing frame, salt bath crucible furnaces and lead baths.

Entscheidend ist dabei eine dem jeweiligen Werkstoff und Wer:;-stück angepaßte Temperatur. Beim FTärten von unterschiedlichen Teilen muß daher die Temperatur jeweils neu eingestellt werden. Dies ist bei den obigen herkömmlichen 1-l'ärmequellen ein langwieriger Vorgang.The decisive factor is the respective material and who:; - piece adjusted temperature. When hardening different parts, the temperature must therefore each time to be set again. This is the case with the above conventional 1-liter heat sources a lengthy process.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zum Härten, Anlassen und dergl. zu entwickeln, bei dem eine rasche und genaue Temperatureinstellung gew#rihrleistet ist. Zur Lösung des Problems wird erfindungsgem1ß vorgeschlagen, daß die Werkstücke mittels optischer Abbildung einer z. F3. elektrischen Strahlungsquelle in einem Arbeitsbrennpunkt erhitzt werden, welche ätrahlungaquelle innerhalb einer Spiegelkarr;rur, liegt, und anschließend dle Abschreckung der Werkstücke in an sich bekannter :-leise erfolgt. Die durch ein solches optisches Gerät erzeugte Temperatur ist in einfacher Weise variierbar durch Veränderung der die Strahlungsquelle speisenden elektrisehm Spane" beinpie3.s- weise durch einen: stufenlos reguilerbaren Vorschaltwiderstand. Derartige optische Geräte bestehen zekmlßig eurer ellipsoidfiirmigen Spiegelkammer, In deren ameren Brennpunkt die Strahlungsquelle instalMert Ist. Das zu er«rde WerkstUek wird dann in dem zweiten, dem zoSenamten Arbeits- brennpunkt darstellenden Brennpunkt, angeordnet, welcher In der Regel außerhalb der Brennkammer liegt. Besonders vorteilhaft erweist sich die Anwendung des erfin- dungsgemäßen Verfahrens bei sogenannten Lufthärtern, bzw. polierten Teilen, die unter Schutzgas erwärmt werden müssen: Durch die auf das Werkstück konzentrierte Wirkung der Wärme- quelle erfolgt kaut eine Erwärmung des das Werkstück umgeben- den Gasmediums, so daß dieses unmittelbar nach Abschaltung der Wärmequelle zur Abschreckung des WerkstUckes dienen kann. The invention is therefore based on the object of developing a method for hardening, tempering and the like, in which a rapid and precise temperature setting is ensured. To solve the problem, it is proposed according to the invention that the workpieces by means of optical imaging of a e.g. F3. electrical radiation source are heated in a working focal point, which radiation source lies within a mirror carriage, and then the workpieces are quenched in a manner known per se. The temperature generated by such an optical device can be varied in a simple manner by changing the Radiation source feeding electricity Spane "beinpie3.s- wise through a: continuously adjustable series resistor to d. Such optical devices are made up of yours ellipsoid- shaped mirror chamber, in whose central focal point the radiation source is installed. That to earth WerkstUek is then in the second, the zo Senam t en work focal point, arranged which In usually outside the combustion chamber. The application of the invention proves to be particularly advantageous proper procedure for so-called air hardeners or polished parts that have to be heated under protective gas: The concentrated effect of the heat on the workpiece source takes place chews a warming of the workpiece surrounding- the gas medium, so that this immediately after shutdown the heat source can serve to deter the workpiece.
