EMI1.1
In dem Patente Nr. 148336 ist ein Verfahren zum Pressen von flüssigem Messing beschrieben, welches im wesentlichen darin besteht, dass die Pressung in dem Zeitpunkt einsetzt, in welchem die Temperatur des Pressgutes zwischen der Solidus- und Liquiduskurve gelegen ist. Hiebei werden Pressformunterteile verwendet, die eine Überhöhung aufweisen, welche das durch den in das Pressgut eindringenden Oberteil verdrängte und daher ansteigende Material aufnimmt und unter Druck hält, wobei diese Überhöhung vorteilhaft als abnehmbarer Ring ausgeführt wird. Hiebei dient ferner auch der Oberteil des Pressformunterteiles als Führung für den Pressstempel.
EMI1.2
Verformung vor dem Pressen annähernd die Form zu geben, die es nach dem fertigen Pressen erhalten soll.
Es werden daher erfindungsgemäss in Hilfsformen Stücke vorgegossen, die nach dem Erstarren in die Pressform übertragen und hier unter Einhaltung der kritischen Temperatur verpresst werden.
In der Zeichnung sind zwei Hilfsformen in den Fig. 1 und 2 beispielsweise dargestellt, während Fig. 3
EMI1.3
Wie aus den Zeichnungen ersichtlich, wird das Material vorgegossen, um eine Rohform zu erhalten und sodann verpresst.

EMI1.1
Patent No. 148336 describes a method for pressing liquid brass, which essentially consists in the pressing commencing at the point in time at which the temperature of the material to be pressed is between the solidus and liquidus curve. The lower parts of the press mold are used here which have an elevation which absorbs the material displaced by the upper part penetrating into the material to be pressed and therefore rising and keeps it under pressure, this elevation advantageously being designed as a removable ring. The upper part of the lower part of the press mold also serves as a guide for the press ram.
EMI1.2
To give the deformation before pressing approximately the shape that it should have after the finished pressing.
According to the invention, pieces are therefore pre-cast in auxiliary molds which, after solidification, are transferred into the press mold and are pressed here while maintaining the critical temperature.
In the drawing, two auxiliary forms are shown, for example, in FIGS. 1 and 2, while FIG
EMI1.3
As can be seen from the drawings, the material is pre-cast in order to obtain a raw shape and then pressed.
