Description

       

  Verfahren     zur        Nachbehandlung    von     Formstikken.       Es ist bekannt, durch Stanzen, Pressen,- Ziehen  oder dergleichen hergestellte Formstücke einer Nach  behandlung nach dem     sogenannten        Nassverfahren    zu  unterziehen, sei es zur Vollendung     ihrer    Form  durch Schleifen     (Entgraten    und     Kantenverrunden),     zur Vorbereitung ihrer     Oberfläche    für eine     Galvani-          sierung    oder Lackierung durch     Reinigen,    Entrosten  und Glätten, oder zur direkten Verschönerung durch  Polieren.

   Das     Nassverfahren    besteht     darin,    dass eine  grosse     Anzahl    der zu     behandelnden    Formstücke, zu  sammen mit     Schleif-    oder Polierkörpern (Körner,       Kugeln    oder dergleichen) von geeigneter Beschaffen  heit und Grösse, und in Gegenwart     -eines    flüssigen  Behandlungsmittels     in    einem Gefäss (Trommel oder  Glocke) rotiert wird.

   Der gewünschte Effekt kommt  dabei durch das mechanische Schleifen und     Schlagen     der den     Gefässinhalt        bildenden    Elemente und durch  gleichzeitige     chemische    Wirkung des Behandlungsmit  tels zustande.  



  Die Erfindung bezieht sich auf die Wahl eines  technisch vorteilhaften     Behandlungsmittels.     



  Bisher war es zum Erzielen bester Wirkung not  wendig, jeweils     ein    dem Material der Formstücke  angepasstes     Behandlungsmittel    zu verwenden. So  waren z. B. für Eisen und seine Legierungen, für  Kupfer und seine Legierungen, für     Aluminium    und  Zink sowie für weitere Metalle jeweils     verschieden-          artige    Behandlungsmittel notwendig. Ausserdem waren  zum Schleifen,     Aufhellen    und     Polieren    von Form  stücken aus gegebenem Material nacheinander drei  verschiedene Behandlungsmittel anzuwenden.

   Neben  dem     offensichtlichen    Nachteil, dass also     eine    grosse  Anzahl von verschiedenen     Mitteln    in Vorrat gehalten  werden musste, führten Verwechslungen zwischen den       äusserlich    schlecht     voneinander    unterscheidbaren Sub  stanzen wegen     mangelhafter    Wirkung zu Ausschuss.    Es sind auch Fälle bekannt; wo die Verwendung  falscher- Mittel zufolge     chemischer        Reaktion    zwischen  Behandlungsmittel und Gut zu Unfällen geführt hat.  



  Das gemäss der     Erfindung    zu verwendende     Be-          handlungsmittel    lässt sich nun mit bestem Erfolg für       alle    Metalle verwenden, und überdies ist für das       Schleifen    (insbesondere     Entgraten)    und     Aufhellen     (Glänzen) einerseits, für das     Polieren    anderseits nur  je eine Variante des Behandlungsmittels     erforderlich.     Daraus ergibt sich eine     evsdente        Verminderung    des  Sortiments und der     Verwechslungsgefähr.     



  Erfindungsgemäss soll das beim     Nassverfahren    zu       verwendende    Behandlungsmittel Borax enthalten.       Eine    wässerige Lösung von 0,25 bis 25     Gramm     Borax pro     Liter    ist als Behandlungsmittel zum Schlei  fen der Formkörper geeignet und verleiht diesen  gleichzeitig die gewünschte     metallisch    reine Ober  fläche.

   Meist wird es zweckmässig sein, diese Borax  lösung durch Beigabe von     mindestens    einem der han  delsüblichen - Netz- und     Reinigungsmittel    zu ergän  zen.     Wenn    die     Passivierungsfähigkeit        eines    solchen  Behandlungsmittels den Anforderungen auf Eisen  nicht genügen sollte, kann noch ein besonderes     Pas-          sivierungsmittel    beigefügt werden.

   Als solches ist bei  spielsweise     Natriumnitrit    geeignet, welches bei Ver  wendung, des Behandlungsmittels auch     zusammen    mit       Formkörpern    aus anderen     Metallen    nicht störend  wirkt.  



  Nach Beigabe von     mindestens    einem der an sich  bekannten     Mittel    zur Erhöhung der Viskosität, z. B.       Carboxymethylzellulose,    eignet sich die wässerige       Boraxlösung    zum Polieren der     Formkörper.    Die den  Gefässinhalt bildenden Elemente     wirken    dann nicht  mehr abtragend wie beim Entgraten und     Reinigen,     sondern polierend     aufeinander    ein. Weiter kann dem       Behandlungsmittel    ein Mittel zur Erhöhung der      Schlüpfrigkeit, beispielsweise Leime,     Eiweissstoffe,          Gummiarabikum,    beigegeben werden.  



  Da das Lösungsmittel     in    den beiden Prozessen   Schleifen und     Reinigen    einerseits,     Polieren    anderseits  - dasselbe ist, kann zwischen den beiden Prozessen       einfach    das erste     Behandlungsmittel    aus dem Gefäss  abgelassen und das zweite     eingefüllt    werden. Es ist  insbesondere keine     Zwischenreinigung    oder     teilweise     Auswechslung der Charge notwendig.



  Process for the aftertreatment of moldings. It is known to subject shaped pieces produced by punching, pressing, drawing or the like to an after-treatment according to the so-called wet process, be it to complete their shape by grinding (deburring and edge rounding), to prepare their surface for electroplating or painting by cleaning, derusting and smoothing, or for direct beautification by polishing.

   The wet process consists in that a large number of the shaped pieces to be treated, together with grinding or polishing media (grains, balls or the like) of a suitable nature and size, and in the presence of a liquid treatment agent in a vessel (drum or bell) is rotated.

   The desired effect comes about through the mechanical grinding and beating of the elements forming the contents of the vessel and through the simultaneous chemical action of the treatment agent.



  The invention relates to the choice of a technically advantageous treatment agent.



  So far, to achieve the best effect it was not necessary to use a treatment agent adapted to the material of the fittings. So were z. B. for iron and its alloys, for copper and its alloys, for aluminum and zinc as well as for other metals, different treatment agents are necessary. In addition, three different treatment agents had to be used in succession for grinding, lightening and polishing moldings made of a given material.

   In addition to the obvious disadvantage that a large number of different agents had to be kept in stock, mix-ups between the substances, which were difficult to distinguish from one another on the outside, led to rejects due to their ineffective effect. Cases are also known; where the use of wrong means has led to accidents due to chemical reaction between the treatment agent and the goods.



  The treatment agent to be used according to the invention can now be used with the greatest success for all metals, and moreover, only one variant of the treatment agent is required for grinding (especially deburring) and brightening (shining) on the one hand, and for polishing on the other. This results in an eventual reduction in the range and the risk of confusion.



  According to the invention, the treatment agent to be used in the wet process should contain borax. An aqueous solution of 0.25 to 25 grams of borax per liter is suitable as a treatment agent for grinding the moldings and at the same time gives them the desired metallically pure surface.

   In most cases it will be useful to supplement this borax solution by adding at least one of the commercially available wetting and cleaning agents. If the passivating ability of such a treatment agent does not meet the requirements for iron, a special passivating agent can be added.

   Sodium nitrite, for example, is suitable as such, which does not have a disruptive effect when the treatment agent is used, even together with molded bodies made of other metals.



  After adding at least one of the known agents for increasing the viscosity, eg. B. carboxymethyl cellulose, the aqueous borax solution is suitable for polishing the moldings. The elements that make up the contents of the vessel then no longer have an abrasive effect, as in deburring and cleaning, but have a polishing effect on one another. Furthermore, an agent for increasing the slipperiness, for example glue, protein, gum arabic, can be added to the treatment agent.



  Since the solvent is the same in the two processes grinding and cleaning on the one hand, and polishing on the other hand, the first treatment agent can simply be drained from the vessel and the second filled in between the two processes. In particular, no intermediate cleaning or partial replacement of the batch is necessary.
