Abstract
Description
Die Erfindung betrifft ein Verfahren, bei dem Metallteile formgebend bearbeitet und anschließend lackiert werden, die für den Einsatz im Innenbereich vorgesehen sind, wie z. B. in der Heimtechnik und -elektronik, im Maschinen- und Appa ratebau oder bei der Möbelherstellung.The invention relates to a method in which metal parts machined and then painted, the are intended for indoor use, such as. B. in home technology and electronics, in machine and app ratebau or furniture manufacturing.
Bei der Formgebung von Metallteilen, wie zum Beispiel beim Stanzen, Schneiden und Biegen ist es notwendig, vor Arbeitsbe ginn ein herkömmliches Stanz- oder Ziehöl auf die Teile aufzu bringen, welches nach erfolgter Bearbeitung der Teile vor dem Lackieren wieder entfernt werden muß. Dazu verwendet man übli che alkalische, saure oder neutrale Reiniger.When shaping metal parts, such as the Punching, cutting and bending is necessary before working Start using conventional stamping or drawing oil on the parts bring which after processing the parts before the Painting must be removed again. You use übli for this alkaline, acidic or neutral cleaners.
Danach können die Teile lackiert werden.The parts can then be painted.
Ein Nachteil des vorstehend beschriebenen Verfahrens besteht darin, daß die notwendige Entfernung des Stanz- oder Ziehöls von den bearbeiteten Teilen vor der Lackierung zusätzliche Zeit und zusätzliches Material erfordert und die Bearbeitung der Teile verzögert und verteuert.A disadvantage of the method described above is in that the necessary removal of the punching or drawing oil of the processed parts before painting Time and additional material required and editing the parts are delayed and made more expensive.
Die Erfindung stellt eine Verbesserung des vorstehend be schriebenen Bearbeitungsverfahrens dar.The invention provides an improvement on the above described processing method.
Sie ermöglicht es, auf den Arbeitsgang Entfetten der Teile vor dem Lackieren zu ver zichten, ohne die Qualität der lackierten Teile zu beeinträch tigen.It allows on to degrease the parts before painting waive without compromising the quality of the painted parts term.
Bei dem erfindungsgemäßen Verfahren wird anstelle des bisheri gen Stanz- oder Ziehöls zur Vorbehandlung der Metallteile ein synthetisches, silikonfreies Schmiermittel im Gemisch mit Al kohol, vorzugsweise in einem Mischungsverhältnis von einem Volumenteil Schmiermittel zu zwei Volumenteilen Alkohol bis zu einem Mischungsverhältnis von einem Volumenteil Schmiermit tel zu zehn Volumenteilen Alkohol, je nach Kompliziertheit der Bearbeitungsvorgänge und der eingesetzten zu bearbeitenden Materialien, in einer Schichtdicke von 10 µm bis 15 µm aufgetra gen. In the method according to the invention instead of the previous i Punching or drawing oil for pretreating the metal parts synthetic, silicone-free lubricant mixed with Al alcohol, preferably in a mixing ratio of one Volume of lubricant to two volumes of alcohol up to to a mixing ratio of one part by volume of lubricant to ten parts by volume of alcohol, depending on the complexity the processing operations and the processes to be used Materials, applied in a layer thickness of 10 µm to 15 µm gene.
Die Mischung wird in üblicher Weise auf die rohen ungeölten Metallteile aufgebracht, zum Beispiel durch Aufsprühen mit Sprühgeräten, durch Aufrollen, durch Aufstreifen mittels Filz oder durch Tauchen.The mixture is applied to the raw unoiled in the usual way Metal parts applied, for example by spraying with Sprayers, by rolling up, by spreading with felt or by diving.
Anschließend muß der Alkohol mindestens 10 Minuten abdunsten. Danach werden die Metallteile ohne vorheriges Entfetten und ohne endgültige Trocknung naß- oder pulverlackiert.Then the alcohol must evaporate for at least 10 minutes. Then the metal parts are degreased and without wet or powder coated without final drying.
Die Erfindung wird in den folgenden Beispielen ausführlich be schrieben:The invention is detailed in the following examples wrote:
Dieses Beispiel betrifft die formgebende Bearbeitung eines verzinkten Stahlbleches zur Herstellung eines Gehäuseteils für heimelektronische Geräte.This example concerns the shaping processing of a galvanized steel sheet for the production of a housing part for home electronic devices.
Das rohe verzinkte Blech wird mit einem Gemisch aus einem Vo lumenteil Schmiermittel und vier Volumenteilen Alkohol vorbe handelt.The raw galvanized sheet is mixed with a mixture of Vo lumen part of lubricant and four volume parts of alcohol acts.
Das Gemisch wird mit einer Textilrolle für Malerarbeiten auf gerollert. Nach einer Abdunstzeit von ca. 30 Minuten können die Stücke mit Wasserlack lackiert und anschließend einge brannt werden.The mixture is applied to a textile roller for painting rolled. After an evaporation time of approx. 30 minutes the pieces are painted with water-based paint and then turned on be burned.
Dieses Beispiel betrifft die formgebende Bearbeitung von Schwarzblech für die Produktion von Rahmen.This example concerns the shaping processing of Black plate for the production of frames.
Das rohe Schwarzblech wird mit einem Gemisch aus einem Volu menteil Schmiermittel und acht Volumenteilen Alkohol vorbehan delt.The raw black plate is made with a mixture of a volu reserve lubricant and eight volumes of alcohol delt.
Das Gemisch wird auf die Schwarzblechteile mit einer Sprühpi stole aufgesprüht.The mixture is sprayed onto the black sheet metal parts sprayed stole.
Nach einer Abdunstzeit von ca. 15 Minuten können die Teile zum Beispiel mit einer Spritzpistole lackiert und anschließend eingebrannt werden. After an evaporation time of approx. 15 minutes, the parts can be Example painted with a spray gun and then be branded.
Dieses Beispiel betrifft die Bearbeitung von Aluminium zur Herstellung einer attraktiven Schmuckblende.This example concerns the processing of aluminum Creation of an attractive decorative cover.
Das Aluminiumblech wird mit einem Gemisch von einem Volumen teil Schmiermittel und vier Volumenteilen Alkohol vorbehan delt.The aluminum sheet comes with a mixture of one volume part of lubricant and four parts by volume of alcohol delt.
Das Gemisch wird mit einem Filz aufgetragen. Nach einer Abdun stzeit von ca. 20 Minuten kann auf die Blende eine Pulverlack ierung aufgebracht werden.The mixture is applied with a felt. After an abdun A powder coating can be applied to the cover for about 20 minutes be applied.
