Description

Das Herstellen von Gesenken und auch Durchbrüchen, wie z. B. solchen in Schnittmatrizen, durch das sogenannte Einsenkverfahren mittels eines in die Gesenk- bzw. Matrizenpla-tte eingedrückten bzw. durch sie gedrückten Senkstempels auf kaltem oder warmem Weg ist bekannt. Dabei wird der Senkstempel im wesentlichen geradlinig eingedrückt, d. h. axial verschoben.The production of dies and breakthroughs, such as. B. those in cutting dies, by the so-called sinking method by means of a die pressed into the die or die plate or pressed through it on a cold or warm path is known. The countersink is pressed in essentially in a straight line, i. H. axially displaced.

Erfindungsgemäß wird nun vorgeschlagen, das Senkverfahren zum Herstellen von Matrizenöffnungen anzuwenden, die gewunden verlaufende Rippen bzw. Nuten haben. Auf diese Weise soll die Aufgabe. gelöst werden, Düsenöffnungen in massiven Matrizen für- das an sich bekannte Auspressen von gewunden genuteten stabförmigen Werkstücken, insbesondere von mit Fasen versehenen Spiralbohrern, herzustellen: Nach der'Erfindung erfolgt das Einsenken bei freier relativer Drehung der Matrize gegenüber einem das Querschnittsprofil und die Nutsteigung des Werkstückes aufweisenden Senkstempel.According to the invention it is now proposed to use the countersinking method for manufacturing of die openings that have serpentine ribs or grooves. That way, the task is supposed to. be solved, nozzle openings in massive matrices for the known pressing of serpentine, grooved rod-shaped workpieces, in particular of twist drills provided with chamfers: According to the invention the sinking takes place with free relative rotation of the die with respect to a das Cross-sectional profile and the groove pitch of the workpiece having countersink punch.

Besoilders vorteilhaft ist dieses Verfahren beim Herstellen von Düsenöffnungen der besagten Form, weil es nicht nur gestattet, spanlos die genaue Form auf einfachem Weg zu erzeugen, sondern auch Düsen, die einen übergang zu einem zylindri ' - sehen bzw. kegeligen Teil am Einlauf haben, entsprechend dem übergang eines genuteten Werkstück- bzw.. Werkzeugteils, z. B. Bohrerteils, in den zylindrischen bzw. kegelig angesetzten Schaftteil. Dies würde auf spanabhebendem Weg schwierig sein. Eine vorzugsweise Weiterbildung des Verfahrens besteht demgemäß dar ' in, die Düsenöffnung mit einem erweiterten zylindrischen oder kegeligen Mündungsteil zu senken, in den die Spiralrippen entsprechend den Nuten des Werkstückes, z. B. eines Spiralbohrers, in dessen Schaftteil auslaufen.Besoilders advantageous is this method in the manufacture of nozzle orifices of said mold, because it is not only permitted without cutting the exact shape in a simple way to produce, but also nozzles that a transition to a cylindricity '- see or have conical portion at the inlet, corresponding to the transition of a grooved workpiece or tool part, e.g. B. drill part, in the cylindrical or conical attached shank part. This would be difficult by machining. A preferred development of the method is accordingly represents' in to reduce the nozzle opening with an extended cylindrical or conical mouth portion, in which the spiral ribs corresponding to the grooves of the workpiece, z. B. a twist drill, expire in the shaft part.

Die Vorrichtung zur Durchführung des Verfahrens weist vorteilhaft eine auf Wälzkörpern gelagerte Halteplatte zur Aufnahme der zu senkenden Matrize auf.The device for carrying out the method advantageously has a holding plate mounted on rolling elements to hold the die to be lowered on.

Die Zeichnung zeigt schematisch ein Ausführungsbeispiel der Vorrichtung zur Durchführung des Verfahrens gemäß der Erfindung. Der erwärmte Matrizenblock a ist auf einer Halteplatte und diese auf dem Kugellager ci zentrisch zum Senkstempel b gelagert Der Senksternpel b ist undrehbar und dringt beim Vorschub in den erwärmten Matrizenblock a über den Auslauf der Spirale hinaus bis zum zylindrischen bzw. kegeligen Teil ein und überträgt durch das selbsttätige Drehen des Matrizenblocke-s a während der Verforinung seinen maßgerechten Querschnitt mit Drall in die Matrize. Nach diesem Vorgang windet sich beim Rückzug des Stempels der Matrizenblock a mit dem eingedrallten Brofil vorn Stempel b ab.The drawing shows schematically an embodiment of the device for performing the method according to the invention. The heated die block a is on a holding plate and this is mounted on the ball bearing ci centered on the die b. The die head b is non-rotatable and penetrates the heated die block a via the outlet of the spiral up to the cylindrical or conical part and transmits through the automatic turning of the die block s a during the deformation its true-to-size cross-section with twist into the die. After this process, when the punch is withdrawn, the die block a with the twisted Brofil at the front of punch b winds away.
