Description
Stahllegierung für gegossene Preß- und Schlaggesenke sowie deren Warmbehandlung Die Herstellung von Gesenken erfolgt im allgemeinen in der Weise,.:daß,ein Rohblock geschmiedet und die erforderliche Gravur durch zum Teil langwierige und kostspielige Bearbeitungsvorgänge in den vollen Block hineingearbeitet wurden. Es bedeutet daher einen wesentlichen Fortschritt der Technik, daß bei Anwendung der vorgeschlagenen Stahllegierung-und des vorgeschlagenen Vexfahrens ein Fortfall der zeitrauhenden und kostspieligen Bearbeitungsvorgänge umdeine wesentliche Werkstoffersparnis erzielt werden.Steel alloy for cast press and punch dies and their heat treatment The production of dies is generally carried out in the manner,.: That, an ingot forged and the necessary engraving through sometimes lengthy and costly Machining operations have been worked into the full block. It therefore means a significant advance in technology that using the proposed Steel alloy and the proposed Vex method an omission of the time-rough and costly machining operations to achieve significant material savings will.
Gegenstand der Erfindung sind gegossene Preß- und Schlaggesenke, die vorzugsweise in vergütetem Zustande in Gebrauch genommen werden, aus einer Stahllegierung mit o,2 bis o,8 % Kohlenstoff, o,7 bis 445% Mangan, o,8 bis 4,o % Chrom, Rest Eisen mit den üblichen Gehalten an Silicium und Verunreinigungen. Die für diesen Zweck vorgeschlagene Stahllegierung kann außerdem noch bis 2,5 % Nickel, bis 2,o % Kobalt, bis 2,o % Vanadin, je bis I,o % Titan, Tantal und/oder Niob einzeln, zu mehreren oder gemeinsam enthalten.The invention relates to cast press and punch dies that are preferably used in a tempered condition, made of a steel alloy with 0.2 to 0.8% carbon, 0.7 to 445% manganese, 0.8 to 4.0% chromium, the remainder iron with the usual levels of silicon and impurities. The for this purpose The proposed steel alloy can also contain up to 2.5% nickel, up to 2.0% cobalt, up to 2.0% vanadium, each up to 1.0% titanium, tantalum and / or niobium individually, to several or included together.
Die Herstellung erfolgt zweckmäßig derart, daß das fertige Gesenk nach Modelloder Schablone mixt einigen Millimetern Zugabe eingeformt wird und durch den Guß die endgültige Form bis auf eine Schleif- oder Bearbeitungszugabe erhält.The production is expediently carried out in such a way that the finished die According to the model or template, add a few millimeters and mix in and through the casting receives its final shape except for a grinding or machining allowance.
Die zweckmäßige Wärmebehandlung der Gußstücke besteht I. aus einem mehrstündigen Glühen bei Temperaturen von 9oo bis IIoo° C, 2. aus einem anschließenden Härten bei Temperaturen oberhalb des AeJ-Punktes in Wasser, Ö loder an der Luft, 3. aus einem Anlassen je nach gewünschter Festigkeit bei Temperaturen zwischen I5o und 7oo°C.The appropriate heat treatment of the castings consists of I. one several hours of annealing at temperatures of 900 to 100 ° C, 2. from a subsequent Hardening at temperatures above the AeJ point in water, oil or in air, 3. from tempering depending on the desired strength at temperatures between 15o and 7oo ° C.
Es haben sich beispielsweise zum Pressen von Leichtmetallen nach der Erfindung her gestellte Gesenke etwa folgender chemischer Zusammensetzung: o,4 %o Kohlenstoff, I,o % Mangan, o,5 % Silicium und i,o % Chrom hervorragend bewährt. Als Preßwerkzeuge für die Kunststoffindustrie sind nach der Erfindung hergestellte Gesenkt nachstellender, , chemischer Zusammensetzung besonders geeignet o,4% o Kohlenstoff, I,4% o Mangan, 0,5 %'o Silicium, 2,5 %ö Chrom und 0,3 %o Vanadin. Nach der Erfindung hergestellte Hammergesenke haben etwa folgende günstige Zusammensetzung o,4% o Kohlenstoff, o,7% Mangan, I,8 %o Nickel und o,8 %,'o Chrom.It has been used, for example, for pressing light metals after the Invention produced dies approximately of the following chemical composition: o, 4% o Carbon, 1.0% manganese, 0.5% silicon and 1.0% chromium have proven their worth. As pressing tools for the plastics industry are manufactured according to the invention Reduced readjusting,, chemical composition particularly suitable o, 4% o carbon, 1.4% manganese, 0.5% silicon, 2.5% chromium and 0.3% vanadium. According to the invention Manufactured hammer dies have roughly the following favorable composition o.4% o carbon, 0.7% manganese, 1.8% nickel and 0.8%, chromium.
