Description

  

      Verfahren        zur        Herstellung    von Federn, insbesondere     für        Uhren       Im Hauptpatent wird ein     Verfahren    zur Herstel  lung von Federn     ferritischer,        kubisch-raumzentrierter     Kristallstruktur, insbesondere für Uhren, beansprucht,  gemäss welchem ein     ferritischer    Werkstoff bzw.

   ein       nichtferritischer,    im Verlaufe des Kaltwalzens jedoch       ferritische    Struktur annehmender metallischer Werk  stoff in     Bandform    homogenisiert und anschliessend  durch Kaltwalzen einer     Querschnittsverminderung     von mindestens 80     0/a    unterworfen wird, derart, dass  eine     Walztextur    gebildet wird, die eine Häufung der       110-Richtung    parallel zur Walzrichtung und der     100-          Ebene    parallel zur     Walzebene    aufweist,

   dass man als  dann die Federbänder in Längsrichtung zum Band  herausschneidet und diese Federbänder einer Nach  behandlung bei 200 bis 600  C     unterwirft.     



  Es hat sich nun gezeigt, dass die Federbänder nicht  nur in Längsrichtung, sondern auch in Querrichtung  zum Band herausgeschnitten werden können.  



  Das erfindungsgemässe Verfahren ist somit da  durch gekennzeichnet, dass ein     ferritischer    Werkstoff  bzw. ein     nichtferritischer,    im Verlauf des     Kaltwalzens     jedoch     ferritische    Struktur annehmender     metallischer     Werkstoff in Bandform homogenisiert und anschlie  ssend durch Kaltwalzen einer     Querschnittsverminde-          rung        von        mindestens        80        %        unterworfen        wird,        derart,     dass eine Walztextur gebildet wird,

   die eine Häufung  der     110-Richtung    parallel zur Walzrichtung und der       100-Ebene    parallel zur     Walzebene    aufweist, dass man  alsdann die Federbänder in Querrichtung zum Band  herausschneidet und diese Federbänder einer Nach  behandlung bei 200     bis    600  C unterwirft.  



  Die im Hauptpatent gemachten Ausführungen  gelten     mutatis        mutandis    auch für das vorliegende Ver  fahren. Als     ferritische    Legierungstypen lassen sich  u. a. ebenfalls die im Hauptpatent erwähnten Legie  rungen verwenden und in Bandform zu breiten     Tex-          turbändern    walzen, nämlich:

      Process for the production of springs, especially for clocks The main patent claims a process for the production of springs with a ferritic, body-centered cubic crystal structure, especially for clocks, according to which a ferritic material or

   a non-ferritic metallic material that takes on a ferritic structure in the course of cold rolling is homogenized in strip form and then subjected to a cross-section reduction of at least 80 0 / a by cold rolling, in such a way that a rolling texture is formed which accumulates the 110 direction parallel to the rolling direction and the 100 plane parallel to the rolling plane,

   that then the spring strips are cut out lengthways to the strip and these spring strips are subjected to an after-treatment at 200 to 600 C.



  It has now been shown that the spring strips can be cut out not only in the longitudinal direction but also in the transverse direction to the strip.



  The method according to the invention is thus characterized in that a ferritic material or a non-ferritic metallic material that takes on a ferritic structure in the course of cold rolling is homogenized in strip form and then subjected to a cross-section reduction of at least 80% by cold rolling, such that a rolling texture is formed,

   which has an accumulation of the 110 direction parallel to the rolling direction and the 100 plane parallel to the rolling plane, so that the spring strips are then cut out in the transverse direction to the strip and these spring strips are subjected to a post-treatment at 200 to 600 C.



  The statements made in the main patent also apply mutatis mutandis to the present process. As ferritic alloy types, u. a. also use the alloys mentioned in the main patent and roll them into wide textile strips in strip form, namely:
