Abstract
The present invention provides a mold method for surface treatment of aluminum component comprising: providing straightening and rounding the aluminum component; the scraping pretreatment; the oxidation prevention and lubrication of scraping; the precise scraping of the aluminum rod. The present invention enables on-line high precision shape finishing and surface cleaning of the aluminum component which satisfies the processing requirement of providing uniformity and consistent treatment by the subsequent extrusion processing as part of the production line in order to produce high quality aluminum, aluminum alloy, aluminum bimetallic and multi-metallic composite profiles and special profiles.
Claims7
A processing method of continuous scraping aluminum rod by molds for precision extrusion comprising:
- a. providing an aluminum component (11);
- b. orientating the aluminum component (11) by a pair of vertical roller molds and a pair of horizontal roller molds;
- c. straightening the aluminum component (11) to form a straightened aluminum component (12) with a series of upper and lower staggered groove roller molds and series of left and right staggered groove roller molds;
- d. rounding the straightened aluminum component (12) to form a round aluminum rod (13) with a series of paired groove roller molds crossing in vertical and horizontal direction;
- e. carving a rifle line onto the round aluminum rod (13) with a rotational scraping tool to form a pretreated aluminum rod (14) when passing through a centrifugal scraping pretreatment unit (24);
- f. coating a volatile anti-oxidation lubricant (33) onto the surface of the pretreated aluminum rod (14) as it passes through a working container (29) which is filled with the volatile anti-oxidation lubricant (33);
- g. scraping off a thin surface scrapings layer from the pretreated aluminum rod (14) with scraping molds (32) when passing through the working container (29), wherein
- (a) a clean aluminum rod (15) is thereby achieved;
- (b) the thin surface scrapings layer breaks into small pieces when the scraping molds (32) hit the rifle line;
- (c) the scraping molds (32) are lubricated;
- (d) the volatile anti-oxidation lubricant (33) coats onto the clean aluminum rod (15) to protect it from secondary oxidation;
- h. passing through an anti-friction nylon sleeve (38), the clean aluminum rod (15) exits from an orientation guide (21) thereafter for a following process of continuous extrusion.
