Description
Gagenmesser für Haakr- oder Zanspanungsmasohlnen zur Holzzerkleine rung ___ ,Fee knife for Haakr or Zanspanungsmasohlnen for wood chopping tion ___,
Die Erfindung betrifft ein Gegenmesser für Hack- oder Zerspanungsmaschinen zur Holzzerklelnerung, an dem die umlaufenden Hackoder Zerspanermesjaer mit einem ger'lngen Abstand von riur wenigen zehntel MUUmetern vorbelstrelchen.The invention relates to a counter knife for chopping or chipping machines for wood chopping, on which the rotating chopping or Machiners with a short distance of just a few tenths of a meter.
Es Ist wichtig, daß die Kante eines derartigen Gegenmessers als Abschluß des Holzzuführungsschachtes zum Zerspanungswerkzeug hin immer scharf bleibt und sich der Abstand zum Messerflugkreis nicht vergrößert.It is important to have the edge of such a counter knife as a finish of the wood feed chute to the cutting tool always remains sharp and the distance to the cutting circle remains not enlarged.
Hierzu werden oft auswechselbare Gegenmesserbalken verwendet, auf die ein Gegenmesser aus hochfestem Stahl an einer Kante aufgeschraubt wird.Replaceable counter knife bars are often used for this purpose which has a counter knife made of high-strength steel screwed onto one edge will.
Aufgabe der Erfindung ist es, die Haltbarkelt dieser Gegenmesser weiter zu erhöhen durch Verwendung von Hartmetall. Bisher glaubte man, derartige Gegenmesser nicht aus Hartmetall herstellen zu können, weil es schwierig ist, Hartmetallstreifen in der erforderlichen Länge herzustellen.The object of the invention is to increase the durability of this counter knife to be increased further through the use of hard metal. It was previously believed that counter knives of this type could not be made from hard metal because it is difficult to produce hard metal strips of the required length.
Die Erfindung löst die Aufgabe durch ein Gegenmesser für Hack- oder Zerspanungsmaschlnen, mit einem ein- und ausschiebbaren Gegenmesserbalken, der außerhalb der Maschine mit dem eigentlichen Gegenmesser bestückt wird, wobei das Gegenmesser aus eingeklemmten Hartmetallstreifen besteht.The invention solves the problem by a counter knife for chopping or Zerspanungsmaschlnen, with a retractable and extendable counter knife bar, which is equipped with the actual counter knife outside the machine, whereby the counter knife is jammed Consists of hard metal strips.
Diese Hartmetallstreifen werden vorzugsweise diagonal im Gegenmesserbalken eingeklemmt. Dabei sind die beiden Schmalseiten dieser Hartmetallstreifen zu einer dachförmigen Schneide mit etwa 90 Kellwinkel ausgebildet.These hard metal strips are preferably placed diagonally in the counter knife bar trapped. The two narrow sides of these hard metal strips form a roof-shaped cutting edge with approximately 90 degrees Kellwinkel trained.
