Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Besprühen von Umform- und Urformwerkzeugen, von Formen zum Druck-, Automatik- und Stranggießen und Brikettieren, insbesondere zum Schmieren von Warmschmiedewerkzeugen. Nach dem erfindungsgemäßen Verfahren wird ein Pulver, beispielsweise bestehend aus Graphit oder auf Graphitbasis, auf die zu schmierenden Oberflächen des betreffenden Werkzeuges (9,10) aufgesprüht. Hierzu wird das Pulver elektrostatisch mit hoher Spannung gegenpolig zu den zu besprühenden Werkzeugen (9,10) aufgeladen, so daß es sich auf den zu schmierenden Oberflächen zusammen mit der ionisierten Luft niederschlägt und dort eine Schmiermittelschicht bildet.

The invention relates to a method and a device for spraying forming and primary forming tools, molds for pressure, automatic and continuous casting and briquetting, in particular for lubricating hot forging tools. According to the method according to the invention, a powder, for example consisting of graphite or based on graphite, is sprayed onto the surfaces of the tool (9, 10) to be lubricated. For this purpose, the powder is charged electrostatically with a high voltage in opposite polarity to the tools (9, 10) to be sprayed, so that it is deposited on the surfaces to be lubricated together with the ionized air and forms a lubricant layer there.
