Abstract
Description
Die Erfindung betrifft Zangen, insbesondere Schneidzangen und/oder Handscheren, die an den jeweiligen Schneidenbereichen partiell gehärtet sind.The invention relates to pliers, in particular cutting pliers and / or hand scissors, which are partially cured at the respective cutting areas.
Bei Zangen und Scheren, wie sie für den Handgebrauch typisch sind und jeweils paarweise zueinander bewegbare Schneiden keilförmiger Ausführung aufweisen, ist es hinreichend bekannt, die der jeweiligen Werkzeugfunktion zugemessenen Schneidenbereiche zur Gewährleistung einer ausreichenden Schneidhaltigkeit und -stabilität einer entsprechenden Wärmebehandlung durch ein Härten zu unterziehen, während andere Werkzeugbereiche, wie Gelenkteile oder Griffelemente unbehandelt bleiben.With pliers and scissors, as are typical for hand use and in pairs mutually movable cutting wedge-shaped design, it is well known to subject the respective tool function metered cutting areas to ensure sufficient cutting resistance and stability of a corresponding heat treatment by curing, while other tool areas, such as hinge parts or handle elements remain untreated.
Bei Werkzeugen relativ kleiner Abmessungen mit empfindlichen, weil weniger massiv ausgebildeten Schneidenteilen, bereitet das Härten in der klassischen, jedoch vielfach erprobten Technologie in den Fällen feiner und dünn ausgearbeiteten Schneidenbereiche verschiedentlich Schwierigkeiten, weil sowohl die lokale und schwer zu beherrschende Erwärmung zur Erreichung der Härtetemperatur als auch das Lokal bestimmte Abschrecken zur Erreichung der martensitischen Gefügestruktur in der Praxis hohe Aufmerksamkeit und große Arbeitssorgfalt erfordert.In tools of relatively small dimensions with delicate because less massive trained cutting parts, the hardening in the classic, but well-tried technology in the cases of fine and thinly prepared cutting areas various difficulties, because both the local and difficult to control heating to achieve the hardening temperature than Also, the local certain quenching to achieve the martensitic microstructure in practice requires high attention and great work care.
Bei den erwähnten Werkzeugarten, wie Schneidzangen und Scheren, ist insbesondere im Bereich der Schneidenzone der Grundwerkstoff sehr dünn ausgeprägt und unterliegt daher leicht einer Überhitzung, was zu den bekannten Folgen von Härtefehlern und nachteiligen Erscheinungen unsachgemäßer Warmbehandlung durch das Härten führt.In the mentioned types of tools, such as cutting tongs and scissors, the base material is very thin particularly pronounced in the cutting zone and therefore is easily subject to overheating, which leads to the known consequences of hardness errors and adverse phenomena improper heat treatment by curing.
Um solche Nachteile vor allem in der sog. Kleinteilfertigung nach Möglichkeit zu vermeiden, wurden im Fachbereich der Härtereitechnik auch bereits Lösungen in Vorschlag gebracht, die für andere Anwendungsfälle, z. B. im Geräte- und Werkzeugbau vorteilhafterweise das sog. partielle Härten unter Verwendung eines Laserstrahls zur Einführung vorsehen (
Die mit Laserstrahlen partiell gehärtete Zone bzw. der Arbeitsbereich von Bauelementen im Stahlbau oder sonstiger Halbzeuge weisen ersichtlich eine verbesserte Festigkeit und bei ausreichender Zähigkeit eine dementsprechend höhere Standhaltigkeit und Stabilität auf, wie sie vom Anwender solcher Produkte erwünscht und erwartet werden.The partial hardened with laser beams zone or the working range of structural elements in steel or other semi-finished products clearly have improved strength and sufficient toughness, a correspondingly higher stability and stability, as desired and expected by the user of such products.
Aus solchen Erfahrungen im Stahlbau oder Fahrzeugbau resultiert die Aufgabe der vorliegenden erfinderischen Lösung. Sie besteht darin, das Laserhärten unter Umgehung prinzipieller technologischer Schranken vorteilhafterweise bei den hochempfindlichen Schneiden oder Schneidenbereichen von Schneidzangen oder auch -scheren, insbesondere für die Elektronikmontage anwendbar zu gestalten.From such experience in steel construction or vehicle construction results in the task of the present inventive solution. It consists in making the laser hardening bypassing basic technological barriers advantageously applicable to the highly sensitive cutting edges or cutting areas of cutting tongs or scissors, in particular for electronics assembly.
Die Lösung dieser Aufgabe besteht darin, in den Bereich der Werkzeugschneiden jeweils eine oder mehrere nebeneinander liegende parallel zur Schneide liegende Laserspuren eingestellter Tiefe einzubringen und die Abkühlung bzw. das Abschrecken des Werkstoffgefüges durch den Wärmeabfluss, also durch Selbstabschrecken, ins Innere des die Schneide tragenden Schneidenschenkels zu bewirken.The solution of this task is to introduce one or more juxtaposed parallel to the cutting edge laser tracks set depth in the field of tool cutting and the cooling or quenching of the material structure by the heat dissipation, ie by self-quenching, inside the cutting edge bearing blade leg to effect.
Damit wird nicht nur eine höhere Festigkeit und Stabilität des Schneidenbereiches, sondern insbesondere auch eine wesentlich verbesserte Schneidhaltigkeit der Werkzeugschneiden, insbesondere an solchen Elektronikzangen, erreicht.This not only a higher strength and stability of the cutting area, but in particular a significantly improved cutting edge of the cutting tool, especially on such electronic tongs achieved.
Ein Ausführungsbeispiel der Erfindung ist nachstehend kurz dargestellt:
Die Zeichnung veranschaulicht den Ausschnitt einer Schneidzange im Bereich seiner Schneidenschenkel. Er zeigt, wie der Schneidenbereich in prinzipieller Art an Feinschneidern, ausgeführt als sog. Vorschneider oder Seidenschneider oder Scheren, angeordnet und ausgebildet ist.An embodiment of the invention is briefly shown below:
The drawing illustrates the section of a cutting pliers in the region of its cutting edges. It shows how the cutting area is in principle arranged and formed on fine cutters, designed as so-called pre-cutters or silk cutters or shears.
Die Zeichnung stellt im Weiteren die Anordnung und den Verlauf der Laserspuren
