Abstract

A circular blade, for general purpose cutters in a kitchen or domestic intensils, has a disc-shaped body which is preformed by press moulding and which is finished in the blade tip region by press elongation. The novelty is that an edge (5) is formed by metal pressing in the blade tip (3) region between the moulded section (1) and the elongated section (2) at least one of the flat side (4) of the blade, the edge extending from the blade tip (3) to the inner flat side (4) of the blade in a stepped manner and being rounded at the edge corner. ADVANTAGE - Increased bending resistance is provided in the redial and axial direction of the blade.

Description

Die Erfindung betrifft ein Rundmesser für Mehrzweck- oder Allesschneider in Küchen- oder Wirtschaftsgeräten, bei dem der scheibenförmige Messerkörper durch Formdrücken vorgeformt und im Bereich der Messerschneide durch Streckdrücken endge­ formt hergestellt ist.The invention relates to a circular knife for multi-purpose or Meat slicer in kitchen or household appliances where the disc-shaped knife body is preformed by compression molding and endge in the area of the knife edge by stretching presses is made.

Rundmesser mit scheibenförmigem Messerkörper und umfangsseitiger Schneide, insbesondere solche für Küchen oder Wirtschaftsgeräte, sind in verschiedenen Formen und Schneidenausführungen bekannt. Bei solchen Rundmessern ist vorwiegend der Bereich der Messer­ aufnahme aus der Messerebene heraus z. B. tellerförmig geformt, um einesteils entsprechende Anpassungen an die Messeraufnahme in der Schneidmaschine zu realisieren oder anderenteils dem Messer unter dem Einfluß der wirkenden Schneiddrücke eine höhere Stabilität zu geben (DRP 2 11 445; DRP 5 90 017; DE-PS 10 22 768; DE-PS 10 07 653).Round knife with disc-shaped knife body and circumferential Cutting edge, especially those for kitchens or commercial appliances, are known in various shapes and cutting edge designs. With such circular knives, the area of the knives is predominant recording from the knife level z. B. shaped like a plate, corresponding adjustments to the knife holder to realize in the cutting machine or otherwise the Knives under the influence of the effective cutting pressures to give greater stability (DRP 2 11 445; DRP 5 90 017; DE-PS 10 22 768; DE-PS 10 07 653).

Während tellerförmig geformte Messerkörper oder auch solche, die mit sickenförmigen Versteifungen versehen sind, eine aus­ reichende Biegestabilität haben, um auch Schneidwaren mit relativ harter Außenhülle glatt und problemlos schneiden zu können, ist es verschiedentlich auch erforderlich, nicht nur dem zentralen Teil des Messerkörpers, sondern insbesondere auch dem Bereich der Messerschneide eine höhere Stabilität zu geben, um verbesserte Funktionseigenschaften zu erreichen.While plate-shaped knife bodies or such, which are provided with bead-like stiffeners, one from have sufficient bending stability to also use cutlery cut relatively hard outer shell smoothly and easily can, it is also necessary in various ways, not only the central part of the knife body, but in particular the area of the knife edge also has greater stability to give in order to achieve improved functional properties.

Das Ziel der Erfindung besteht darin, Rundmesser für Alles­ schneider hinsichtlich ihres Gebrauchsverhaltens zu ver­ vollkommnen.The aim of the invention is circular knives for everything to tailor regarding their usage behavior perfect.

Der Erfindung liegt die Aufgabe zugrunde, an durch Formdrücken und Streckdrücken hergestellten scheiben- bzw. tellerförmigen Messerkörpern dem Bereich der Messerschneide eine in radialer und axialer Richtung des Rundmessers wirksame erhöhte Biege­ stabilität zu geben.The invention has for its object to by pressing and stretching presses produced disc-shaped or plate-shaped Knife bodies the area of the knife edge in a radial effective and increased bending in the axial direction of the circular knife to give stability.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in dem Bereich der Messerschneide, wo während der Formgebung des inneren Teiles des Messerkörpers keine Werkstoffumformung erfolgte, ein zusätzlicher, teilweise in den Messerkörper und in den Messerschneidenbereich hineinreichender Spannungs­ zustand erzeugt wird, wobei im Bereich der Messerschneide zwischen dem formgedrückten Messerabschnitt und dem streckge­ drückten Messerabschnitt mindestens an einer der Messerflach­ seiten eine durch Metalldrücken hergestellte Kante ausgebildet ist, die von der Messerschneide zur inneren Messerflachseite hin stufenförmig verläuft und deren Kantenecken gerundet aus­ geführt sind.This object is achieved in that Area of the knife edge, where during the shaping of the inner part of the knife body no material deformation was carried out, an additional, partially in the knife body and tension reaching into the knife edge area condition is generated, being in the area of the knife edge between the molded knife section and the streckge pressed knife section at least on one of the knife flat sides formed an edge made by metal pressing is that from the knife edge to the inner knife flat side is stepped and the edges of the edges are rounded are led.

Mit der erfindungsgemäßen Lösung der Aufgabe ist die Möglich­ keit geschaffen, dem Rundmesser jene durchgängig erforderliche Stabilität und Steifigkeit zu geben, die besonders für das Schneiden fester, mit harter Außenschale versehener Waren erfor­ derlich ist.With the solution of the task according to the invention, this is possible created, the circular knife has the continuously required To give stability and rigidity, especially for that Cutting of solid goods with a hard outer shell is required is such.

Außerdem schafft die erfindungsgemäße Lösung die Voraussetzungen dafür, diese Messer in geringerer Blechdicke herzustellen, was sich nicht nur fertigungstechnologisch vorteilhaft auswirkt, sondern auch im Hinblick auf eine ökonomische Materialver­ wendung sich als vorteilhaft darstellt.In addition, the solution according to the invention creates the conditions for making these knives in a smaller sheet thickness, what is not only advantageous in terms of production technology, but also with regard to an economical material supply turns out to be advantageous.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel kurz erläutert werden. Die Zeichnung stellt eine teilweise Seitenansicht eines erfindungsgemäß ausgeführten Rundmessers teilweise im Schnitt dar. The invention is based on an exemplary embodiment are briefly explained. The drawing represents one partial side view of a designed according to the invention Circular knife partially in section.  

Der in bekannter Weise ausgeführte Messerkörper besteht aus dem inneren formgedrückten Messerabschnitt 1 und dem äußeren streckgedrückten Messerabschnitt 2, an dem zugleich die Messer­ schneide 3 ausgebildet ist.The knife body executed in a known manner consists of the inner molded knife section 1 and the outer stretch-pressed knife section 2 , on which the knife edge 3 is formed at the same time.

Im Bereich zwischen den Messerabschnitten 1 und 2 ist an min­ destens einer der Messerflachseiten 4 eine durch Metalldrücken hergestellte Kante 5 angeordnet, die von der Messerschneide 3 kommend zur inneren Messerflachseite 4 hin stufenförmig verläuft und deren Kantenecken gerundet ausgeführt sind.In the area between the knife sections 1 and 2 , at least one of the knife flat sides 4 has an edge 5 made by metal pressing, which comes from the knife edge 3 to the inner knife flat side 4 and has a rounded edge.
