in einem Arbeitsgange.in one operation.
Vorliegende Erfindung betrifft ein dreiteiliges Schmiedepressen-Gesenk zur Herstellung gratloser Schmiedestücke in einem Arbeitsgange. The present invention relates to a three-part forging press die for manufacture burr-free forgings in one operation.
Vorrichtungen, welche bisher zur Formgebung und Entgratung des Schmiedestückes in ein und demselben Arbeitsgange vorgeschlagen sind, bewirkten die Entgratung entweder durch Abkneifen oder durch Herausstoßen des überflüssigen Materials aus einem Loch des Schmiedestückes.Devices that were previously used for shaping and deburring the forging are proposed in one and the same operation, either caused the deburring by pinching off or by pushing the excess material out of a hole in the forging.
Die erstere Arbeitsweise (das Abkneifen) ist bei einigermaßen zähem Preßgut nicht mehr möglich und liefert außerdem wenig saubere Ware. Die zweite Methode (das Herausstoßen) ist auf Hohlkörper beschränkt und deshalb auf massive Schmiedestücke überhaupt nicht anwendbar.The former mode of operation (pinching) is not possible with somewhat tough pressed material more possible and also delivers less clean goods. The second method (pushing out) is limited to hollow bodies and therefore not applicable at all to solid forgings.
Zur Herstellung in Form gepreßter und entgrateter Schmiedestücke wird gemäß der neuen Erfindung ein dreiteiliges, aus einem mittleren, feststehenden Preßring, einem beweglichen Ober- und einem beweglichen Unterstempel bestehendes Gesenk mit dem besonderen nachbeschriebenen Arbeitsgange dieser Teile verwendet.For the production of pressed and deburred forgings according to the new invention a three-part, consisting of a central, fixed press ring, a movable one An upper die and a movable lower die with the special work process described later Parts used.
Beiliegende Zeichnung gibt in schematischer Darstellung einen Begriff von der Ausführung und Wirkungsweise dieser Gesenke.The accompanying drawing provides a schematic representation of the design and mode of action of these dies.
Die Fig. i, 2 und 3 zeigen die Vorrichtung, eine massiv gepreßte Eisenkugel enthaltend, in Ansicht, Querschnitt und Grundriß, die Fig. 4, 5 und 6 dieselbe zur Her-Figs. I, 2 and 3 show the device Containing a solidly pressed iron ball, in view, cross-section and plan, FIGS. 4, 5 and 6 use the same to produce
stellung eines Preßstückes von prismatischer Form.position of a pressed piece of prismatic shape.
Bei Beginn des Arbeitsganges legt sich der bewegliche Unterstempel c infolge des unteren Preßdruckes fest gegen den mittleren feststehenden Preßring b an, während der Oberstempel in der Höchststellung gedacht sei. In dieser Lage bildet der bewegliche Unterstempel c und das feststehende Mittelstück (Preßring b) als seitliche Begrenzung eine Hohlform, in welche das zu pressende erhitzte Schmiedestück eingebracht wird. Der Preßring b hat entweder eine ganz bestimmte Höhe, die sich nach der Stärke und Form des herzustellenden Gegenstandes richtet, oder aber er hat in einer gewissen Höhe ein oder mehrere Aussparungen.At the beginning of the operation, the movable lower punch c, as a result of the lower pressing pressure, rests firmly against the central, fixed pressing ring b , while the upper punch is intended to be in the maximum position. In this position, the movable lower punch c and the stationary center piece (press ring b) form a hollow shape as a lateral boundary into which the heated forging to be pressed is introduced. The press ring b either has a very specific height, which depends on the strength and shape of the object to be manufactured, or it has one or more recesses at a certain height.
Nach Einbringen des Gutes in die Form läßt man den Oberstempel α aus seiner Hochstellung herabgehen; dadurch wird das Preßgut zusammengedrückt, so daß es die Form ausfüllt. Bei fortgesetzt wirkendem Drucke wird das überschüssige Material zwischen Oberstempel α und Preßring b als Grat (nach Fig. i, 2 und 3) oder durch die Aussparungen im Preßring b als Strang (nach Fig. 4, 5 und 6) so lange herausgedrückt, bis das Material allseitig von den Gesenken eingeschlossen ist, das Preßstück somit die gewünschte Stärke und Gestalt erreicht hat.After the goods have been placed in the mold, the upper punch α is allowed to go down from its upper position; this compresses the material to be pressed so that it fills the mold. When the pressure continues to act, the excess material between the upper punch α and the press ring b is pressed out as a burr (according to FIGS. I, 2 and 3) or through the recesses in the press ring b as a strand (according to FIGS. 4, 5 and 6) until the material is enclosed on all sides by the dies, so that the pressed piece has reached the desired strength and shape.
Nun senkt man das Untergesenk c und läßt den Oberstempel α weiter herabgehen. Es schert hierbei der Preßring b infolgeNow you lower the lower die c and let the upper punch α go down further. It shears the press ring b as a result
seiner Gestaltung als Schnitt den Grat oder Strang von dem abwärts gedrückten Preßstück
ab, worauf dieses gratlos dem Gesenk entnommen werden kann.
5its design as a cut the burr or strand from the pressed piece pressed down, whereupon this can be removed from the die without burrs.
