Description
Durchbohrte Werkzeuge, bei denen die Bohrung dazu dient, das Kühlmittel an die Schneidkanten zu führen, sind bekannt. Derartige Werkzeuge haben aber den Nachteil, daß sie durch diese Durchbohrungen wesentlich geschwächt sind. Mit Rücksicht auf die erforderliche Festigkeit müssen solche Werkzeuge gegenüber den sonst gebräuchlichen deshalb einen entsprechend größeren Querschnitt besitzen, wodurch ein Mehrverbrauch an Stahl bedingt ist. Während des Härteprozesses erleiden ferner derartige durchbohrte Werkzeuge auch leicht 'Verziehungen oder ungleiche Härtestellen.Cannulated tools in which the hole is used to bring the coolant to the cutting edges to lead are known. However, such tools have the disadvantage that they are significantly weakened by these through-holes are. With regard to the required strength, such tools must be opposite the otherwise common therefore have a correspondingly larger cross-section, whereby an increased consumption of steel is caused. These also suffer during the hardening process pierced tools also easily 'warps or unequal hardness points.
Diese Ubelstände sollen gemäß der Erfindung dadurch vermieden werden, daß nicht das Werkzeug, sondern ein dazu passender Werkzeughalter Durchbohrungen besitzt, um das Kühl- oder Schmiermittel zu den Schneidkanten zu leiten.These inconveniences are to be avoided according to the invention in that not that Tool, but a matching tool holder has holes to allow the To direct coolant or lubricant to the cutting edges.
Ein solcher Dreh- und Hobelstahlhalter ist in der Zeichnung dargestellt, und es zeigt
Abb. ι eine Seitenansicht,
Abb. 2 einen vorderen Querschnitt,
Abb. 3 einen hinteren Querschnitt und
Abb. 4 eine Aufsicht des Stahlhalters.Such a turning and planing steel holder is shown in the drawing, and it shows
Fig. Ι a side view,
Fig. 2 a front cross-section,
Fig. 3 shows a rear cross section and
Fig. 4 is a top view of the steel holder.
Durch die Seele des Werkzeughalters α führen von einer Kühlkammer k Kanäle η nach Kammern I. Die Kammern I sind nach der Seite der Aussparungen b, c, f (Abb. 2) offen und werden durch die einzuschiebenden Schneidstähle d (Abb. 2) abgeschlossen, wodurch eine Kühlung des Stahles bewirkt wird. Von den Kammern I der Aussparungen δ und c führen weitere Kanäle m (Abb. 1, 2, 4) direkt zur Spanabhubstelle und kühlen hier das Werkzeug auch an seiner Schneide. Von der Kammer I in der Aussparung f (Abb. 2) führen zwei Kanäle 0 zur Spanabhubstelle, um das Kühlen und Schmieren beim Abstechen sowie Gewindschneiden auf allen Angriffsseiten des Stahles zu sichern. Die Befestigung der Schneidstähle am Halter geschieht in bekannter Weise mittels Spannbügel. Through the core of the tool holder α , channels η lead from a cooling chamber k to chambers I. The chambers I are open on the side of the recesses b, c, f (Fig. 2) and are closed by the cutting tools d (Fig. 2) to be inserted , whereby a cooling of the steel is effected. From the chambers I of the recesses δ and c, further channels m (Fig. 1, 2, 4) lead directly to the chip removal point and here also cool the tool at its cutting edge. Two channels 0 lead from chamber I in recess f (Fig. 2) to the chip removal point in order to ensure cooling and lubrication during parting and thread cutting on all attack sides of the steel. The cutting tools are fastened to the holder in a known manner by means of clamps.
Durch Einsetzen einer nicht gezeichneten, einstellbaren und mit einer Durchbohrung versehenen Verschlußscheibe in die Kammer k wird die Führung des Kühlmittels nach der entsprechenden Schneidkante eines eingeschobenen Werkzeuges geregelt. Die nicht gebrauchten und unter sich getrennten Leitungen η können dann durch die eingebrachte Scheibe verschlossen werden.By inserting an adjustable closure disk (not shown), which is provided with a through-hole, into the chamber k , the guidance of the coolant is regulated according to the corresponding cutting edge of an inserted tool. The unused and separated lines η can then be closed by the inserted disk.
