Description

Vorliegende Erfindung bezieht sich auf ein Verfahren zum Stauchen und Fertigformen des elektrisch erhitzten Endes einer stangenförmigen Werkstoffmasse, bei dem während des Stauchens .der Abstand .der Elektroden, von denen eine als Führungselektrode ausgebildet ist, durch Ausweichen der anderen, als Widerlager dienenden Elektrode vergrößert wird.The present invention relates to a method of upsetting and final molding of the electrically heated end of a rod-shaped material mass, during the upsetting .the distance .of the electrodes, one of which is used as a guide electrode is formed by evading the other electrode serving as an abutment is enlarged.

Bei derartigen an sich bekannten Verfahren hat man das Fertigformen durch zusätzliche Bearbeitung der Oberfläche der Stauchstellen, insbesondere durch Hämmern oder Walzen, durchgeführt. Dadurch entstehen verhältnismäßig verwickelte Maschinen und auch Erschwerungen des Arbeitsverfahrens, so daß sich Vorschläge dieser Art praktisch nicht einführen konnten. Bei anderen bekannten Schmiedevorrichtungen liegt die einteilige Widerlagerelektrode unverrückbar fest. Hier fehlt völlig eine äußere Einwirkung auf die Oberfläche der Stauchstelle.In such a method known per se, one has finished molding by additional processing of the surface of the upsetting points, in particular by Hammering or rolling. This creates relatively complex ones Machines and also complications of the work process, so that suggestions of this Art practically could not introduce. In other known forging devices the one-piece abutment electrode is immovable. One is completely missing here external influence on the surface of the upsetting point.

Die dargelegten Schwierigkeiten und Nachteile werden erfindungsgemäß dadurch beseitigt, daß, ausgehend von dem eingangs genannten Verfahren, die Werkstoffmasse zunächst bei unveränderlichem Elektrodenabstand aufgestaucht und der Werkstoff anschließend hieran unter gleichzeitigem Ausweichen der Widerlagerelektrode und fortgesetztem Stauchen an dem Ausweichen quer zur Stauchbewegung über -die Oberfläche des Fertigstückes hinaus verhindert wird.The difficulties and disadvantages set out are made in accordance with the invention eliminated by the fact that, based on the method mentioned at the beginning, the material mass initially upset with unchangeable electrode spacing and then the material on this while simultaneously evading the abutment electrode and continuing Compression at the deflection transversely to the compression movement over the surface of the finished piece addition is prevented.

Eine zur Durchführung des Verfahrens geeignete Stauclimaschine kennzeichnet sich dadurch, daß die ausweichende Widerlagerelektrode in einer sie umhüllenden Büchse derart geführt ist, daß ihre am zu stauchenden Stangenende anliegende Begrenzungsfläche in der Ausgangslage mit der Stirnfläche der umhüllenden Büchse bündig abschließt.Identifies a storage air conditioning machine that is suitable for carrying out the process characterized in that the evasive abutment electrode in an enveloping them The bushing is guided in such a way that its boundary surface rests against the end of the rod to be compressed in the starting position is flush with the face of the enveloping sleeve.

Die Zeichnung zeigt eine Ausführung des Erfindungsgedankens am Beispiel der schematisch wiedergegebenen Hauptteile einer Elektrostauchmaschine.The drawing shows an embodiment of the inventive concept using the example the schematically reproduced main parts of an electric upsetting machine.

Fig. i gibt die Stauchmaschinenteile in der Ausgangslage, Fig. 2 nach Beginn der Stauchung, Fi:g. 3 am Ende des Stauchvorganb s wieder, während Fig. q, das auf diese Weise hergestellte Werkstück veranschaulicht.Fig. I gives the upsetting machine parts in the starting position, Fig. 2 Start of compression, Fi: g. 3 again at the end of the upsetting process, while Fig. Q, illustrates the workpiece produced in this way.

Wie die Fig. i zeigt, wird der zu stauchende kalte Stab i zwischen die Klemmbacken :2 der sog. Führungselektrode 3 eingespannt und mit einem Ende q, gegen den beweglichen Gesenkboden 5 angeschlagen. Dieses Anschlagen erfolgt durch Druck auf das andere Stangenende 6. Der Gesenkboden 5 führt sich im Gesenk 7. Das Gesenk 7 ist eingespannt in die Elektrode B. Die Elektroden 3 und 8f sind, solange keine Stange i eingespannt ist, voneinander isoliert und mit den beiden Sekundärpolen eines Transformators 9 verbunden. Die Stange hebt jedoch die Isolierung auf und stellt eine unmittelbare Verbindung der Elektroden dar. Wird der Primärstromkreis geschlossen, so fließt zwischen den beiden Elektroden 3 und 8 ein Strom, der den mit i bezeichneten Stangenteil erhitzt. Der Druck auf dias, kalte Stangenende 6 bewirkt eine Aufstauchung des erhitzten Stangenteiles i bei io.As shown in FIG. I, the cold rod i to be compressed is between the clamping jaws: 2 of the so-called guide electrode 3 clamped and with one end q, posted against the movable die bottom 5. This is done by Pressure on the other end of the rod 6. The die bottom 5 is guided in the die 7. The Die 7 is clamped in the electrode B. The electrodes 3 and 8f are as long as no rod i is clamped, isolated from each other and with the two secondary poles a transformer 9 connected. However, the rod removes the insulation and represents a direct connection of the electrodes. It becomes the primary circuit closed, a current flows between the two electrodes 3 and 8, which the with i denoted rod part heated. The pressure on the cold end of the bar 6 causes a compression of the heated rod part i at io.

Ist die Stauchung so weit fortgeschritten, daß der Durchmesser des gestauchten Teiles io den inneren Durchmesser des Gesenlces 7 erreicht bat (Fig. 2), so wind die Widerlagerelektrode 5 in das Gesenk 7 .zurückgezogen. Der:glei.chmäßig gedrückte, erhitzte Wemkstoff paßt sich @beim fortgesetzten Stauchen den Wandungen des Gesenkes an. Die Bewegung des Ge!senkbodens 5 miuß idem Nachrücken des laufend sich .aufstauchenden Werkstoffes angepaßt werden. Auf diese Weise füllt allmählich das Stauchgut das ganze Gesenk aus und päßt sich dabei @genau @des,sen Innenfürm @an, ohne Falten, 1;Tberlappungen oder Verbrennungen zu zeigen (Fig. 3 und q.).If the compression has progressed so far that the diameter of the compressed part io the inner diameter of the Gesenlces 7 reached bat (Fig. 2), the abutment electrode 5 is withdrawn into the die 7. The: equivalent Pressed, heated fabric adapts to the walls with continued upsetting of the die. The movement of the bottom 5 must be continuously moving upwards be adapted to .aufstuchenden material. In this way it gradually fills up the upsetting material from the whole die and fits @ exactly @ the, sen inner shape @an, without wrinkles, 1; showing overlaps or burns (Fig. 3 and q.).

Gesenk 7, Klemmbacken 2 und WiderlagerelektrOde 5 sind auswechselbar. Der Abstand -der hellen Elektroden 3 und 8 -ist veränderlich. Hierdurch und durch Einstellung verschiedener Stauchdrucke und Heizspannungen können Werkstücke verschiedener Querschnitte und Werkstoffe verarbeitet werden.Die 7, clamping jaws 2 and abutment electrode 5 are exchangeable. The distance between the bright electrodes 3 and 8 is variable. Through this and through Different upsetting pressures and heating voltages can be set for different workpieces Cross-sections and materials are processed.
