Schneidwerkzeug, bestehend aus einem Halter und einem auswechselbaren SchneideinsatzCutting tool, consisting of a holder and an exchangeable cutting insert
Die Erfindung betrifft ein Schneidwerkzeug, das aus einem Halter und einem auswechselbaren Schneideinsatz besteht, der ohne besondere Kiemmittel im Halter befestigt ist.The invention relates to a cutting tool which consists of a holder and a replaceable cutting insert which is mounted in the holder without special clamping means.
Werkzeuge dieser Art zum Drehen bzw. Abstechen sind beispielsweise aus dem DE-GM 1.887.564 und der DE-OS 22 06 654 bekannt. Sie sind jedoch noch verhältnismäßig kompliziert und nicht für größere Belastungen geeignet.Tools of this type for turning or parting are for example from DE-GM 1.887.564 and DE-OS 22 06 654 known. However, they are still relatively complicated and not for greater loads suitable.
Der Erfindung liegt die Aufgabe zugrunde, ein Schneidwerkzeug zu schaffen, das einfacher zu handhaben und sowohl hinsichtlich des Halters als auch in Bezug auf den Schneideinsatz mit kleinerem Aufwand herstellbar ist.The invention has for its object to provide a cutting tool that is easier to use and Can be produced with less effort both in terms of the holder and in terms of the cutting insert is.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Halter mit einer Ausnehmung versehen ist, deren Oberseite schräg und deren Unterseite parallel zur Längsachse des Halters verläuft, daß die Ausnehmung im Halter-Querrichtung als Nut und der Schneideinsatz als dazuThis object is achieved according to the invention in that the holder is provided with a recess, the top of which obliquely and the underside of which runs parallel to the longitudinal axis of the holder, that the recess in the holder transverse direction as a groove and the cutting insert as to it

passende Feder ausgebildet und daß eine Öffnung im Halter vorgesehen ist.suitable spring formed and that an opening is provided in the holder.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ein fester Sitz des Schneideinsatzes im Halter auch bei rauherem Betrieb gewährleistet ist und trotzdem der Schneideinsatz leicht aus dem Halter gelöst werden kann. Dazu kommt, daß der relativ dünn gestaltete Schneideinsatz kostengünstig herzustellen ist, was insbesondere für Schneideinsätze aus Hartmetall gilt.The advantages achieved by the invention are in particular that a tight fit of the cutting insert is guaranteed in the holder even with rough operation and nevertheless the cutting insert easily out of the holder can be solved. In addition, it is relatively thin designed cutting insert is inexpensive to manufacture, which is especially true for cutting inserts made of hard metal is applicable.
Die Erfindung wird anhand der Zeichnungen beschrieben. Es zeigenThe invention is described with reference to the drawings. Show it

In addition, the opening 5 serves - e.g. with the help of a pin - to release the cutting insert 6 from the

In Halter-Querrichtung ist die Ausnehmung 2 als Nut 7 und der Schneideinsatz 6 als dazu passende Feder 8 ausgebildet.In the transverse direction of the holder, the recess 2 is a groove 7 and the cutting insert 6 is a matching tongue 8 educated.
Durch diese Nut-Feder-Verbindung von Schneideinsatz 6 und Halter 1 sowie die schräg zur Halter-Längsachse verlaufende Oberseite 4 der Ausnehmung 2 ergibt sich eine sichere Fixierung des Schneideinsatzes 6, wobei letzterer einfach und schnell eingesetzt und - durch leichten Druck - aus dem Halter 1 gelöst werden kann.This tongue-and-groove connection of cutting insert 6 and holder 1 as well as the upper side 4 of recess 2, which runs obliquely to the longitudinal axis of the holder, results in a secure fixation of cutting insert 6, the latter being inserted easily and quickly and - by applying slight pressure - out of the holder 1 can be solved.
Fig. 4, 5 und 6 zeigen den Schneideinsatz 6 mit dem als Feder 8 ausgebildeten, der Schneide 9 abgewandten Teil. Die Winkel el , & , V1 und 5" sind die verschiedenen bei einem Abstechwerkzeug erforderlichen Freiwinkel. Die Winkel oL· und ρ werden zweckmäßigerweise ihrem absoluten Betrag nach zur Hälfte in den Halter 1 eingearbeitet, was durch entsprechende Gestaltung der Ausnehmung 2 geschieht. Dadurch sitzt der Schneideinsatz 6 bewußt etwas schief im Halter 1, was aus den Fig. 2 und 3 zu ersehen ist (Winkel 1/2^C und 1/2 ρ ). Dieses teilweise Einarbeiten der WinkeloC und ρ in den Halter 1 hat zur Folge, daß der Schneideinsatz 6 einfach und damit kostengünstig herzustellen ist.4, 5 and 6 show the cutting insert 6 with the part designed as a spring 8 and facing away from the cutting edge 9. The angles el, &, V 1 and 5 "are the different clearance angles required for a parting tool. The angles oL · and ρ are expediently worked in half of their absolute value in the holder 1, which is done by appropriate design of the recess 2 2 and 3 (angles 1/2 ^ C and 1/2 ρ), the cutting insert 6 deliberately sits slightly obliquely in the holder 1. This partial incorporation of the angles oC and ρ in the holder 1 results that the cutting insert 6 is simple and therefore inexpensive to manufacture.
