Description
Locheisen Die bekannten Locheisen bestehen aus einem Stück, wobei der Stahl an den Schneidkanten durch Vergütung oder Härtung verbessert wird. Wiederholtes Nachschleifen macht das Locheisen unbrauchbar. Das Gebrauchsmuster vermeidet diesen Nachteil durch den Vorschlag eines Locheisens mit auswechselbaren Schneidmessern. Punches The known punches consist of one piece, whereby the steel at the cutting edges is improved by tempering or hardening. Repetitive Regrinding makes the punch unusable. The utility model avoids this Disadvantage due to the suggestion of a punch with exchangeable cutting blades.
Die Erfindung ist in der Zeichnung dargestellt, wobei die unteren Figuren mögliche Querschnitte durch das Messer angeben.The invention is illustrated in the drawing, with the lower Figures indicate possible cross-sections through the knife.
Die Vorteile des Gebrauchsmusters liegen in folgendem : 1. Bei Verschleiß des Messers braucht nur dieses ersetzt zu werden.The advantages of the utility model are as follows: 1. When worn of the knife only needs to be replaced.
Der Halter bleibt unverändert brauchbar. Der Vorteil, der hierin liegt, ist besonders bei größeren Locheisen mit komplizierter Profillochung erheblich. The holder remains usable without any changes. The advantage of this is particularly significant for larger punches with complicated profile holes.
2. Die Verwendung einer hochwertigen Stahlqualität kann auf das Messer beschränkt werden, was das ganze Instrument verbilligt.2. The use of a high quality steel can be applied to the knife be limited, which makes the whole instrument cheaper.
3. Der Außendurchmesser des schneidenden Teils bei Locheisen gemäss der Erfindung bleibt auch bei wiederholtem Nachschleifen zylindrisch, während bei Locheisen der alten Art sich durch wiederholtes Nachschleifen der Außendurchmesser derart verändert, daß, besonders beim Aushauen sehr dicken Werkstoffs, eine nachteilige konische Aufdornung dieses Stoffes auftritt.3. The outside diameter of the cutting part for punch according to the invention remains cylindrical even with repeated regrinding, while with Old-style punches are made by repeatedly regrinding the outside diameter changed in such a way that, especially when cutting out very thick material, a disadvantageous one conical flaring of this material occurs.
