KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf eine Preßvorrichtung, mittels welcher das Preßgut nicht nur von zwei Seiten, beispielsweise von oben und unten, sondern auch in anderer Richtung, beispielsweise horizontal, der Wirkung von Preßstempeln ausgesetzt wird. Beispielsweise sollen Hohlkörper, wie kreuz-, T-, winkel- usw. förmige Gasmuffen durch Pressung hergestellt werden, wobei nicht nurThe invention relates to a pressing device by means of which the material to be pressed not only from two sides, for example from above and below, but also from another Direction, for example horizontal, is exposed to the action of press rams. For example should hollow bodies, such as cross, T, angle, etc. shaped gas sleeves Pressing can be produced, not only
ίο die äußere Form erzeugt werden muß, sondern auch Hohlräume unmittelbar in der Presse entstehen sollen. Charakteristisch ist für die Presse, daß der Teil, welcher das Aufdrücken des Preßstempels auf das Gesenk zur äußeren Formgebung bewirkt, auch die Bewegung der übrigen Preßstempel veranlaßt, so daß je nach der Größe des von dem Preßstempel auszuübenden Druckes auch der Druck des Matrizenstempels zunimmt. Je stärker also z. B.ίο the outer shape must be created, but rather cavities should also be created directly in the press. Is characteristic of the Press that the part that pushes the ram onto the die to the outer Shaping causes the movement of the rest of the ram, so that depending on the size of the pressure to be exerted by the press ram and the pressure of the die ram increases. So the stronger z. B.
die die Innenform erzeugenden Stempel auf das Material einwirken, um so größer wird der Druck der die äußere Form bildenden Pressenteile sein, wodurch, das Herausdrücken von Material aus der äußeren Preßform durch die Innenstempel und mithin die Gratbildung vermieden wird.the stamp that creates the inner shape act on the material, the larger it becomes be the pressure of the press parts forming the outer shape, thereby pushing out of material from the outer mold through the inner punch and thus the formation of burrs is avoided.
Ein Ausführungsbeispiel einer solchen Presse ist auf der Zeichnung in den Fig. 1 und 2 im Vertikalschnitt und Grundriß dargestellt. Der Preßtisch α ist mit seinem Führungszapfen a1 in dem Untergestell b auf- und abverschiebbar gelagert. Ein Hebel c mit Gewicht c1 sucht den Preßtisch in die Höhe zu bringen. Auf dem Preßtisch ruht das Gesenk d, während der Gegenstempel d1 in einem Querhaupt e befestigt ist, das sich auf Säulen f auf- und abbewegen kann. Die Säulen sind, wie ersichtlich, in dem Untersatz b befestigt. Zur Bewegung des Querhauptes e ist eine Schraubenspindel e1 angeordnet, die durch eine beliebige Vorrichtung in Drehung versetzt und in einer irgendwie fest gelagerten Mutter abwärtsgeschraubt werden kann.An embodiment of such a press is shown in the drawing in Figs. 1 and 2 in vertical section and plan. The press table α is mounted with its guide pin a 1 in the subframe b up and down. A lever c with weight c 1 seeks to raise the press table. The die d rests on the press table, while the counter punch d 1 is fastened in a cross head e which can move up and down on columns f. As can be seen, the columns are fastened in the base b. To move the crosshead e , a screw spindle e 1 is arranged, which can be set in rotation by any device and screwed down in a nut that is somehow fixedly mounted.
Bei dem dargestellten Beispiel ist der Preßtisch, wie Fig. 2 erkennen läßt, kreuzförmig, und es sind noch besondere Führungslappen g auf dem Untersatz b angeordnet, welche den Kreuzarmen des Preßtisches α noch eine weitere Führung bieten. Auf dem Preßtisch a bewegen sich in schwalbenschwanzförmigen Nuten vier schlittenartige Backen h. Diese stellen durch Gelenkstangen i mit dem Unterteil b in Verbindung. Die Backen h tragen an ihren oberen Enden nach innen vorspringende Nocken h1, und an dem den Preßstempel d1 tragendem Querhaupt ist ein Flansch h11 vorgesehen.In the example shown, the press table, as can be seen in FIG. 2, is cross-shaped, and special guide tabs g are also arranged on the base b , which provide the cross arms of the press table α yet another guide. Four slide-like jaws h move in dovetail-shaped grooves on the press table a. These are connected to the lower part b by means of articulated rods i . The jaws h have inwardly projecting cams h 1 at their upper ends, and a flange h 11 is provided on the crosshead carrying the ram d 1.
Das Gesenk d und der Stempel d1 sind so geformt, daß sie die Außenform beliebiger. Hohlkörper bilden. Die Fig. 3 und 4 lassen zwei Beispiele für eine T- und eine winkelförmige Gasmuffe erkennen, während das aus Fig. 2 ersichtliche Gesenk für eine kreuzförmige Muffe bestimmt ist. Entsprechend dieser Kreuzform werden auch sämtliche vier Backen h benutzt. Die eigentliche Pressung üben diese Backen durch besonders eingesetzteThe die d and the punch d 1 are shaped so that they have any external shape. Form hollow bodies. 3 and 4 show two examples of a T-shaped and an angled gas sleeve, while the die shown in FIG. 2 is intended for a cross-shaped sleeve. In accordance with this cross shape, all four jaws h are also used. The actual pressing is exercised by these jaws through specially used
