Description

Völlig selbsttätig arbeitende elektrische Abbrennstumpfschweißmaschine mit hydraulischem Antrieb Das Hauptpatent 683 oig hat eine völlig selbsttätig arbeitende elektrische Abbrennstumpfschweißmaschine mit hydraulischem Antrieb und Richtungsumkehr res Schlittens beim Vorwärmen zum Gegenstand.Fully automatic electric flash butt welding machine with hydraulic drive The main patent 683 oig has a completely automatic electric flash butt welding machine with hydraulic drive and direction reversal res slide to the object when preheating.

Die Umkehrung findet dadurch statt, daß beim Zusammenstoßen der Werkstücksteile durch den Stromdurchgang ein einfaches Maximalrelais anspricht und die Umkehrung vorschaltet. Durch das Aufeinandertreffen der Werkstücksteile wird gleichzeitig die Schlittenbewegung gehemmt, und es findet ein Überdruck statt, der den Fühlkontakt p schließt und die Umkehrung vollzieht. Diese Umkehrung wird begrenzt durch -das Trennen der Werkstücke; indem Idas Maximalrelais durch den unterbrochenen Stromdurchgang abfällt und wieder auf Vorwärtsgang umschaltet. Bei vorliegender Erfindung findet das jeweilige Umsteuern im Gegensatz zu der elektrisch-mcehanisch bzw. elektrisch-hydraulisch betätigten Anordnung beim Hauptpatent rein mechanisch statt. An Stelle des Maximalrelais wird ein einfacher Kontakt n gesetzt, der geschlossen ist und die Schlittenbewegung auf Vorwärtsgang schaltet. Unter Zugrundelegung der im Hauptpatent dargestellten schematischen, hydraulischenArbeitsweise ersetzt dieser Kontakt n den Kontakt n und .gleichzeitig das Maximalrelais m. Durch die Schlittenbewegung findet beim Auftreffen der fest eingespannten Werkstücke ein Überdruck statt. Der Überdruck schließt den Fühlkontäkt p und öffnet gleichzeitig den Kontakt iz. Dadurch wird der Magnetschalter f ab- und der Magnetschalter q eingeschaltet urid die Schlittenbewegung umgekehrt. Durch die Umkehrung hört der Überdruck auf, der Kontakt 3z schließt und p öffnet wieder, und die Schlittenbewegung schaltet wieder vorwärts. Durch ein Drosselventil x läßt sich die Umkehrung entsprechend einstellen,. so daß eine Trennung der Werkstücke- absolut stattfindet. Dieser Vorwärmumsteuervoi-gang wiederholt sich nun so lange, bis die Werkstücksteile erhitzt sind und :das Abbrennen beginnt. Da. -beim Abbrennen ein Überdruck nicht stattfinden kann, erfolgt auch keine Umschaltung. Das Einleiten der schlagartigen Stauchung und die Stromabschaltung nach erfolatern Abbrennen geschieht in der im Hauptpatent angegebenen Weise.The reversal takes place in that when the workpiece parts collide through the passage of current a simple maximum relay responds and the reverse upstream. The meeting of the workpiece parts is simultaneously the carriage movement is inhibited, and there is an overpressure that makes the sensing contact p closes and reverses. This reversal is limited by -that Separating the workpieces; by Idas the maximum relay through the interrupted current passage drops and switches back to forward gear. In the present invention finds the respective change of direction in contrast to the electric-mechanical or electric-hydraulic actuated arrangement in the main patent takes place purely mechanically. Instead of the maximum relay a simple contact n is set, which is closed and the slide movement switches to forward gear. Based on those shown in the main patent schematic, hydraulic operation, this contact n replaces contact n and at the same time the maximum relay m. by the slide movement takes place when it hits overpressure takes place on the firmly clamped workpieces. The overpressure closes the Fühlkontäkt p and opens the contact iz at the same time. This will make the magnetic switch f off and the magnetic switch q on and the slide movement reversed. By the reversal stops the overpressure, the contact 3z closes and p opens again and the slide moves forward again. Through a Throttle valve x can be reversed accordingly. so that a separation the work piece takes place absolutely. This preheating reversal process is repeated now until the workpiece parts are heated and: the burning off begins. There. -When an overpressure cannot take place when burning, there is no switchover. The initiation of the sudden compression and the power cut-off after the successor Burning off takes place in the manner indicated in the main patent.
