A kind of aluminium alloy extrusions burnishing device
Technical field
The present invention relates to shape extrusion field, specifically a kind of aluminium alloy extrusions burnishing device.
Background technology
In order to form layer oxide film in aluminum alloy surface, ensure aluminium alloy not by extraneous corrosion, aluminium alloy extrusions needs the process carrying out following steps successively before dispatching from the factory: 1. surface preparation: clean Surface of profile by the method for chemistry or physics, expose pure matrix, be beneficial to obtain complete, fine and close artificial oxidation's film, also can obtain minute surface or unglazed (sub-light) surface by mechanical means; 2. anodic oxidation: through the section bar of surface preparation, under certain processing condition, matrix surface generation anodic oxidation, generates the AL of one deck densification, porous, strong adsorptive power
