Description
Die Erfindung betrifft eine Doppelkopfnagel-Stauchmaschine, bei der zwei Köpfe gleichzeitig an einem schrittweise vorgeschobenen Draht mittels zweier Klemmbackenpaare und einem Stauchstempel angestaucht werden.The invention relates to a double head nail upsetting machine in which two heads simultaneously on a wire that is advanced step by step by means of two pairs of clamping jaws and upset with an upsetting punch.
Sie besteht im wesentlichen darin, daß ein Teil der Klemmbacken in einem in Achsrichtung des Drahtes verschiebbaren Körper ίο senkrecht zum Draht verschiebbar gelagert ist.It consists essentially in the fact that part of the clamping jaws in an axial direction the wire slidable body ίο mounted perpendicular to the wire slidably is.
Ein weiterer Bestandteil der Erfindung ist, daß die Übertragung des Preßdruckes auf die verschiebbaren Klemmbacken durch Walzen erfolgt.Another component of the invention is that the transfer of the pressure to the sliding jaws is done by rolling.
Der Fortschritt gegenüber bekannten derartigen Einrichtungen liegt darin, daß die Klemmbacken infolge ihrer geraden Führung parallel zur Werkstückachse bei jeder beliebigen Drahtstärke voll zur Anlage an den Draht gelangen.The advance over known such devices is that the Clamping jaws due to their straight guidance parallel to the workpiece axis for any Full wire gauge to rest on the wire.
Auf der Zeichnung ist der Erfindungsgegenstand im Schnitt in einer beispielsweisen Ausführungsart dargestellt, und zwar zeigen:The subject of the invention is shown in section in an exemplary manner in the drawing Design shown, namely show:
Abb. ι einen Längsschnitt, Abb. 2 einen Querschnitt von A-B der Abb. i, währendFig. Ι a longitudinal section, Fig. 2 a cross section from AB of Fig. I, while
Abb. 3 und 4 das Pressen eines Doppelkopfnagels in geöffnetem und zusammengepreßtem Zustande der Klemmbacken veranschaulichen. Fig. 3 and 4 the pressing of a double headed nail in the open and pressed together Illustrate the condition of the clamping jaws.
Zwischen den Stauchstellen angreifende Klemmvorrichtungen b sind annähernd parallel verschiebbar zur Mittelachse des zu bearbeitenden Drahtes c angeordnet zwecks Herstellung der ersten Stauchstelle. Zwecks Herstellung der nächsten Stauchstelle können die Klemmvorrichtungen b gegen eine feststehende oder langsamer bewegte Klemmvorrichtung α verschoben werden. Clamping devices b engaging between the upsetting points are arranged displaceably approximately parallel to the central axis of the wire c to be processed for the purpose of producing the first upsetting point. In order to produce the next upsetting point, the clamping devices b can be shifted against a fixed or more slowly moving clamping device α.
Die Klemmvorrichtungen b sind symmetrisch an einer gemeinsamen, verschiebbaren
Hülse e beliebigen Querschnitts angeordnet, so daß die an sich verschieden gerichteten
Arbeitsdrucke der einzelnen Werkzeuge der Klemmvorrichtungen b sich infolge der gemeinsamen
Befestigungen gegeneinander aufheben.
Die Klemmvorrichtungen b erhalten zweckmäßig den Anpreßdruck unter Zwischenschaltung
von Walzen d übertragen, so daß die Verschiebung der Klemmvorrichtungen b nur
sehr wenig durch den an sich starken Anpressungsdruck beeinflußt sind.The clamping devices b are arranged symmetrically on a common, displaceable sleeve e of any cross-section, so that the differently directed working pressures of the individual tools of the clamping devices b cancel each other out due to the common fastenings.
The clamping devices b are expediently transmitted with the contact pressure with the interposition of rollers d , so that the displacement of the clamping devices b are only very little influenced by the contact pressure, which is strong per se.
Der Arbeitsgang beim Stauchen an zwei oder mehreren Stauchstellen ist folgender:The process for upsetting at two or more upsetting points is as follows:
Nach dem Vorschub des Drahtes c gehen die Klemmvorrichtungen α und b zusammen und halten den Draht c fest. Hierauf erfolgt zunächst das Abschneiden des zuvor fertiggestellten Nagels, was auf beliebige, bekannte Art geschieht, wobei gleichzeitig eine Spitze o. dgl. mit an dem Drahtende erzeugt werden kann.After the advance of the wire c , the clamping devices α and b go together and hold the wire c firmly. This is followed by cutting off the previously finished nail, which is done in any known manner, and at the same time a tip or the like can be produced at the end of the wire.
Danach vollführen die Klemmvorrichtungen b und der Preßkopf / eine Bewegung gegen die Klemmvorrichtung α hin, wodurch die Stauchung der beiden Stauchstellen hervorgerufen wird.Thereafter, the clamping devices b and the press head / perform a movement against the clamping device α , whereby the compression of the two upsetting points is caused.
Die Haltevorrichtungen b und der Preßkopf / gehen jetzt wieder in ihre alte Lage zurück und lassen durch Auseinandergehen das bearbeitete Stück los.The holding devices b and the press head / now go back to their old position and let go of the processed piece by moving apart.
Darauf bringt der Vorschub weiteres Material nach der Arbeitsstelle, und das Spiel wiederholt sich.The feed then brings more material to the job and the game repeated.
