Description

Messer mit harten Schneiden ltr Fleischereikutter Die laufende Erhöhung der Schnittgeschwindigkeit in Fleischereikuttern führt zu einer stärkeren Belastung der Kuttermesser. Die Schneiden-stumpfen rascher ab. Um hier abzuhelfen, kann man den Spitzenwinkel der Schneide vergrößern. Damit wird aber der spezifische Leistungsbedarf des Kutters höher. Man kann dadurch zu einer Verbesserung kommen, daß man die Messerschneiden harter macht. Die üblichen Härteverfahren von Stahl geben keine genügende Härte, wenn das Messer hinreichend zäh sein soll.Knife with hard edges ltr butcher's cutter The current increase the cutting speed in butcher's cutters leads to a higher load the cutter knife. The cutting edges blunt faster. To remedy this, one can increase the point angle of the cutting edge. But this is the specific power requirement of the cutter higher. You can get an improvement by cutting the knife edges harder makes. The usual hardening processes for steel do not give sufficient hardness, if the knife should be sufficiently tough.

Erfindungsgemäß wird daher vorgeschlagen, daß die Schneide durch einen Hartmetallauftrag gehärtet wird.According to the invention it is therefore proposed that the cutting edge by a Hard metal application is hardened.

Vorzugsweise handelt es sich dabei um einen Vorgang des umgekehrten Erodierens, bei dem durch Energieentladungen molekulare Teile iner Hartmetall-Elektrode in den Schneidenwerkstoff eindiffundieren und ggfs. beine beliebig dünne Hartmetallschicht aufbauen.This is preferably a reverse process Eroding, in which, through energy discharges, molecular parts of a hard metal electrode Diffuse into the cutting edge material and, if necessary, an arbitrarily thin hard metal layer build up.

Es entsteht eine feste stoffschlüssige Verbindung zwischen Messer und Auftragsschicht.A firm material connection is created between the knife and application layer.

Hierdurch kann der Kern zäh bleiben, während die Härte der Schneide bis zu 72 RC steigen kann.This allows the core to remain tough while the hardness of the cutting edge can rise up to 72 RC.

Dieses Verfahren hat gegenüber dem Auftragsschnweißen oder ähnlichen Verfahren den Vorzug einer außerordentlichen Vereinfachung des Schleifvorganges. Die Schneidenform läßt sich unter günstigen Zerspanungsbedingungen herstellen, während für das Scharfschleifen des gehärteten Schneide nur ein kleiner Aufwand erforderlich ist.This process has a lot more than build-up welding or the like Method has the advantage of an extraordinary simplification of the grinding process. The cutting edge shape can be produced under favorable machining conditions while Only a small amount of effort is required for sharpening the hardened cutting edge is.
