Description

Bei elektrischen Widerstandsschweißmaschinen ist es bereits bekannt, den durch Zusammenpressen der Werkstücke entstehenden Grat durch elektrisch angetriebene Stempel zu beseitigen; jedoch hat es sich gezeigt, daß das bisher Bekannte verbesserungsbedürftig ist, weil die Brauchbarkeit derartiger Einrichtungen von dem Raumbedarf und der Einfachheit der Ausführung abhängig ist.In electrical resistance welding machines, it is already known that by pressing together removing burrs from the workpieces by means of electrically driven punches; however, it has been shown that what is known so far is in need of improvement because the usefulness of such facilities on the space requirements and the simplicity of the Execution is dependent.

Das Wesentliche der Erfindung besteht darin, daß das Stempelpaar von einem Solenoid mit zwei in ein und derselben Achse angeordneten und gegeneinander wirkenden Kernen angetrieben wird, und daß die beiden Stempel,The essence of the invention is that the pair of stamps from a solenoid with two cores arranged in one and the same axis and acting against one another is driven, and that the two punches

z. B. durch ein beiderseits eingreifendes Zahn- 1S trieb, zwangläufig gegeneinander verschiebbar sind.z. B. drove by a mutually engaging tooth 1 S , are inevitably mutually displaceable.

Die Abb. ι der Zeichnung veranschaulicht in schematischer Weise den Erfindungsgegenstand in Seitenansicht, die Abb. 2 die Anordnung der Stempel mit den in der Schweißmaschine festgeklemmten Werkstücken im Grundriß. Im übrigen bezeichnen i'die Werkstücke, 2 die bekannten Klemmbacken der Stumpfschweißmaschine, 3 und 4 die Stempel, 5 das Solenoid, a5 6 das Grundgestell mit Lagerflächen zur Aufnahme und Führung der Stempel und des Solenoids, 7 eine Druckfeder. 8 den Zahntrieb.The Fig. Ι of the drawing illustrates schematically the subject of the invention in side view, Fig. 2 the arrangement of the punch with the workpieces clamped in the welding machine in plan. Incidentally, i 'denotes the workpieces, 2 the known clamping jaws of the butt welding machine, 3 and 4 the punch, 5 the solenoid, a 5 6 the base frame with bearing surfaces for receiving and guiding the punch and the solenoid, 7 a compression spring. 8 the pinion.

Die Stempel 3 und 4 sind an dem einen Ende für die Werkstücke in runder Form an den Preßflächen entsprechend ausgespart, an dem anderen Ende als Solenoidkern ausgebildet, so daß sie bei Tätigkeit des Solenoids 5 gegeneinander gerichtet angezogen werden. Da der Stempel 4 hakenförmig ausgebildet ist, werden die beiden Stempel von beiden Seiten auf das Werkstück gepreßt. Um zu bewirken, daß die Stempel gleidizeitig an dem angestauchten Grat des Werkstückes angreifen, also ein exzentrischer Druck auf das schweißwarme Werkstück vermieden wird, ist das in Zähne der Stempel eingreifende Zahntrieb 8 vorgesehen, welches die einfache Aufgabe hat, die gleichmäßig zurückzulegenden Wege zwangläufig zu regeln. Das Zahnrad 8 ist in einem festen Lager des Grundgestelles 6 drehbar gelagert. Die Feder 7 hat den Zweck, die Stempel in die gezeichnete Lage zurückzubringen, wenn das Solenoid außer Tätigkeit gesetzt wird.The stamps 3 and 4 are at one end for the workpieces in a round shape to the Pressing surfaces recessed accordingly, designed as a solenoid core at the other end, see above that they are attracted directed against each other when the solenoid 5 is active. Since the Stamp 4 is hook-shaped, the two stamps are on both sides of the Workpiece pressed. In order to ensure that the stamp simultaneously on the upset ridge attack the workpiece, i.e. an eccentric pressure on the workpiece that is warm to weld is avoided, the pinion gear 8 engaging in the teeth of the punch is provided, which has the simple task of inevitably closing the distances to be covered evenly rules. The gear 8 is rotatably mounted in a fixed bearing of the base frame 6. The purpose of the spring 7 is to bring the stamp back into the position shown when that Solenoid is disabled.

Da es von ganz besonderem Vorteil ist, wenn die Stauchgratpresse unmittelbar nach Beendigung des Stauchvorganges, also beiSince it is of particular advantage if the edging press immediately after Completion of the upsetting process, i.e. at

»5 größter Schweißhitze, in Tätigkeit gesetzt wird, kann das Solenoid mit einer beliebigen selbsttätigen Schaltvorrichtung einer Schweißmaschine in Verbindung gebracht werden, derart, daß im gleichen Moment der Unterbrechung des Schweißstromes dasselbe Schaltorgan dazu benutzt wird, das Soienoid 5 in Tätigkeit zu setzen. »5 greatest welding heat is put into operation, the solenoid can having an arbitrary automatic shift device of a welding machine to be associated, such that at the same moment of the interruption of the welding current the same switching element is used to set the Soienoid 5 in activity.

Abb.Fig.

Die Anordnungsweise des Erfindungsgegenstandes zeichnet sich dadurch aus, daß man von dem Bau der Schweißmaschine vollkommen unabhängig ist und jede bereits gebaute Schweißmaschine damit versehen werden kann.The arrangement of the subject matter of the invention is characterized by the fact that it is completely independent of the construction of the welding machine and any welding machine that has already been built can be equipped with it.
