Description

Harmonikaartig faltbare Abdeckung für Werkzeugmaschinen, insbesondere für Schleifmaschinen Die Patentanmeldung A 25550 lb/67a betrifft eine harmonikaartig faltbare Abdeckung für Werkzeugmaschinen, die aus dünnen Polyamidplatten hergestellt ist. Dieser Kunststoff hat gegenüber dem sonst zur Herstellung der Gleitbahnen benutzten Preß.span den Vorteil, daß er durch Öl und Wasser oder durch Ölemulsionen nicht angegriffen wird.Cover for machine tools that can be folded in the manner of a harmonica, in particular for grinding machines The patent application A 25550 lb / 67a concerns a harmonica-like foldable cover for machine tools made from thin polyamide sheets is. This plastic has compared to the one otherwise used to manufacture the slideways Preß.span has the advantage that it is not affected by oil and water or by oil emulsions is attacked.

Die Erfindung bezweckt, die Temperaturbeständigkeit der aus Polyamid hergestellten Abdeckungen zu verbessern. Erfindungsgemäß dienen zur Herstellung der Abdeckungen dünne Polyamidplatten, die unter Vakuum mit Aluminium überzogen sind. Aluminium verbindet sich, wie Versuche zeigen, fest mit der Oberfläche des Polyamids und bildet so auf dem Polyamid eine dünne Metallschicht, die wärmeverteilend wirkt und damit örtlich hohe Erwärmungen des Polyamids durch heiße Späne u. dgl. verhindert.The invention aims to improve the temperature resistance of the polyamide to improve manufactured covers. According to the invention are used for production the covers are thin polyamide sheets coated with aluminum under vacuum are. As tests show, aluminum bonds firmly to the surface of the Polyamide and thus forms a thin metal layer on the polyamide that distributes heat acts and thus locally high heating of the polyamide due to hot chips and the like. prevented.

Das Aufbringen von Metallüberzügen auf faltbare Abdeckungen ist an sich bekannt. Man hat bereits auf die Kunstlederüberzüge, also auf Gewebe, Metall aufgespritzt, um sie wärmebeständiger zu machen. Hierbei leidet aber die Biegefestigkeit der Gewebe, so daß an Stelle von Metall andere Kunststoffe, z. B. Silicongummi, als Oberflächenschutz verwendet wurden. Bei Abdeckungen aus Polyamid beeinflußt dagegen die Metallschicht die Biegefestigkeit nicht.Applying metal coatings to foldable covers is on known. You already have on the artificial leather covers, i.e. on fabric, metal sprayed on to make them more heat resistant. Here, however, the flexural strength suffers the fabric, so that instead of metal, other plastics such. B. silicone rubber, were used as surface protection. Affected with covers made of polyamide on the other hand, the metal layer does not have the flexural strength.
