Description

  

  Achse mit mindestens einer Verdickung, insbesondere für Fahrräder, und     Verfahren     zu deren Herstellung.    Die bisher bekannten Achsen mit minde  stens einer Verdickung sind aus dem Vollen,  das heisst aus einem Werkstück vom Durch  messer der Verdickung durch Drehen oder  Schmieden im Gesenk herausgearbeitet.  



  Die Achse gemäss der Erfindung, worun  ter auch eine Welle zu verstehen ist, zeichnet  sich dadurch aus, dass die Verdickung durch  Stauchung in axialer Richtung erzeugt ist.  Bei der Herstellung dieser Achse wird also  von einem     Werkstück    vom Durchmesser der  unverdickten Achse ausgegangen und kann,  da das     Abdrehen    oder     Schmieden    wegfällt,  zirka 30 bis 50 % an Material und Arbeits  zeit erspart     werden.     



  Ausführungsbeispiele des Erfindungs  gegenstandes seien anhand der Zeichnung er  läutert.  



  Fig. 1 veranschaulicht im Vertikalschnitt  und im Grundriss eine Vorrichtung zur Her  stellung von Achsen mit Verdickungen aus  einem glattzylindrischen     Stahlstück    nach  Fig. 2.    Nachdem das Werkstück b vom Durch  messer d     auf    elektrischem Wege in kurzer  Frist auf Rotglut erwärmt worden ist, wird  dasselbe senkrecht     in        die    eigens dazu einge  richtete Stauchvorrichtung (die an jeder Ex  zenter- oder Spindelpresse angebracht wer  den kann) auf die einstellbare Widerlager  schraube w gestellt. Das Ingangsetzen der  Maschine bezw. das Niedergehen des Stauch  kopfes<I>a</I> auf das erwärmte Werkstück<I>b</I> be  wirkt eine Verdickung b' zwischen dem Ge  senkteil g und dem Stauchkopf a.

   Diese Ver  dickung     kann        entsprechend    der Fasson des  Gesenkteils grösser oder kleiner, wie auch in  verschiedenen Formen gewählt werden. Die  Achszapfenlänge kann durch Einstellen des       Werkstückes    in der Höhe mittels der Wider  lagerschraube     w    geregelt werden.  



  Durch Umkehren und Wiedererwärmen  des Werkstückes b kann mindestens eine  zweite Verdickung     angestaucht    werden, so  dass eine Fahrradachse nach     Fig.    3 mit zwei      Verdickungen b1 vom. Durchmesser D ent  steht.  



  An dieser Achse sind dann noch diese  Verdickungen sowie die beiden Enden zu  egalisieren und die erforderlichen     Keilhalmen     einzufräsen.  



  Fig. 4 stellt eine horizontale Stauchvor  richtung dar, mit welcher gleichzeitig zwei  Verdickungen     bi        hervorgebracht        werden     können.  



  Die     Erwärmung    des     Arbeitsstückes    kann  durch die     beweglichen    Kupferelektroden e er  folgen.  



  Fig. 5 bis 10 veranschaulichen einige ver  schiedene     Ausführungen    von Achsen und  Achsteilen, welche sieh durch Stauchung bei    entsprechender (Testalt der Pressköpfe und  Gesenke herstellen lassen.



  Axle with at least one thickening, in particular for bicycles, and method for their production. The previously known axes with at least one thickening are worked out from the solid, that is, from a workpiece with the diameter of the thickening by turning or forging in the die.



  The axis according to the invention, which also includes a shaft, is characterized in that the thickening is produced by upsetting in the axial direction. In the manufacture of this axle, a workpiece with the diameter of the unthickened axle is assumed and, as there is no turning or forging, around 30 to 50% of material and labor time can be saved.



  Embodiments of the subject invention are explained with reference to the drawing.



  Fig. 1 illustrates in vertical section and in plan a device for the manufacture of axes with thickenings from a smooth cylindrical piece of steel according to FIG. 2. After the workpiece b has been electrically heated to red heat in a short period of time, the same is perpendicular placed on the adjustable abutment screw w in the upsetting device set up specifically for this purpose (which can be attached to any eccentric or screw press). The start of the machine respectively. the lowering of the upsetting head <I> a </I> onto the heated workpiece <I> b </I> produces a thickening b 'between the lowering part g and the upsetting head a.

   This Ver thickening can be selected larger or smaller, as well as in different shapes, according to the shape of the die part. The journal length can be regulated by adjusting the height of the workpiece using the abutment screw w.



  By reversing and reheating the workpiece b, at least one second thickening can be upset, so that a bicycle axle according to FIG. 3 with two thickenings b1 from. Diameter D arises.



  These thickenings and the two ends must then be leveled on this axis and the necessary wedge stems milled in.



  Fig. 4 shows a horizontal Stauchvor direction, with which two thickenings bi can be produced at the same time.



  The workpiece can be heated by the movable copper electrodes.



  Fig. 5 to 10 illustrate some ver different designs of axles and axle parts, which can be produced by upsetting at the appropriate (Testalt of the press heads and dies.
