Description

Das Kaltsenkverfahren ist bekannt. Es ist ein spanloses Arbeitsverfahren, bei dem mittels gehärteter Stempel, auch Patrizen oder Pfaffen genannt, auf kaltem Wege durch Anwendung von hohen Drücken Formgesen.ke hergestellt werden. Es beruht darauf, daß der gehärtete Stempel unter hohem Druck in das Werkzeuggegengesenk eingepreßt wird. Da dies infolge Kaltverfestigung des ungehärteten :Materials nur Abis zu einer gewissen Tiefe gelingt, erfolgt das Kaltsenken meist in mehreren Stufen unter Zwischenglühen.The cold sinking process is known. It is a non-cutting working process, with hardened stamps, also called patrices or priests, on cold Ways to be made by applying high pressure Formgesen.ke. It is based ensure that the hardened punch is pressed into the tool counter-die under high pressure will. Since this is due to work hardening of the uncured: material only Abis to one If a certain depth is achieved, cold countersinking usually takes place in several stages with intermediate annealing.

Die Herstellung von Schnittplatten nach diesem Verfahren ist nicht bekannt und Gegenstand vorliegender Erfindung. Die Wirtschaftlichkeit des Verfahrens besteht insbesondere bei komplizierten, lohnintensiven Schnittwerkzeugen. Als neu wird vorgeschlagen, daß bei diesem hier angemeldeten Verfahren entweder aus dem kaltgesenkten Block 2 die Schnittplatte senkrecht zur Preßrichtung gemäß Bild i herausgesägt wird, wobei der Stempel i bis zu einer Tiefe über die Schnittplattendicke 5 hinaus in den Gesenkblock 2 eingedrungen ist, oder es werden nach Bild. 2 zwei Platten 3 und 4 übereinandergelegt, von denen die obere Platte 3 später als Schnittplatte dient. Der gehärtete Stempel i durchdringt dann im Kaltsenkverfahren die obere Platte 3 vollständig und die untere Platte 4 nur zum Teil. Die sich hieraus ergebende Lippenbildung. bei b oder Auswölbung bei a läßt sich durch Überfräsen leicht beseitigen. Die Trennfläche der Säge ist in Bild i und 2 durch Pfeil und gestrichelte Linie gekennzeichnet.The production of cutting plates according to this process is not known and the subject of the present invention. The economy of the process exists particularly in the case of complicated, labor-intensive cutting tools. As new it is proposed that in this process registered here either from the cold-countersunk block 2 the cutting plate perpendicular to the pressing direction as shown in Figure i is sawed out, the punch i to a depth beyond the thickness of the cutting plate 5 has penetrated into the die block 2, or it will be according to picture. 2 two Plates 3 and 4 placed one on top of the other, of which the upper plate 3 will later be used as a cut plate serves. The hardened punch i then penetrates the upper plate using the cold sinking process 3 completely and the lower plate 4 only partially. The resulting lip formation. at b or bulge at a can easily be removed by milling over. The interface the saw is marked in picture i and 2 by arrow and dashed line.

PATENTANSPRÜCHE: i Anwendung des Kaltsenkverfahrens zur Genauformung der Durchbrüche in Schnittplatten. PATENT CLAIMS: i Application of the cold countersinking process for precise shaping of the openings in cut plates. 2. Kaltsenkverfahren nach Anspruch i, dadurch gekennzeichnet, daß der Senkstempel bis zu einer über die endgültige Schnittplattendicke (s) hinausgehenden Tiefe in den Gesenkstahlblock (2) eingedrückt wird, worauf von, diesem die obere Schicht als Schnittplatte, z. B. durch Sägen, abgetrennt wird. 2. Cold sinking method according to claim i, characterized characterized in that the countersink up to one over the final cutting plate thickness (s) depth is pressed into the die steel block (2), whereupon of, this the upper layer as a cut plate, z. B. by sawing is separated. 3. Kaltsenkverfahren nach Anspruch i, dadurch gekennzeichnet, daß einer Schnittplatte (3) etwa richtiger Dicke eine zweite Platte (4) unterlegt und der Senkstempel bis zu einer zweckmäßigen Tiefe unter die Oberfläche der Unterplatte (4) in beide Platten hineingedrückt wird, worauf die an,der Unterseite der Schnittplatte entstandene Lippe oder Auswölbung (a), z. B. durch Überfräsen, beseitigt wird. Angezogene Druckschriften: »Fertigungstechnik«, 2. Jahrgang, Heft 6, i944.3. Cold sinking method according to claim i, characterized in that a cutting plate (3) a second plate (4) of approximately the correct thickness underneath and the countersink up to to a suitable depth below the surface of the sub-plate (4) in both plates is pressed in, whereupon the resulting on, the underside of the cutting plate Lip or bulge (a), e.g. B. by overmilling is eliminated.
