Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum profile processing, and more particularly to an aluminum profile surface burr finishing device. BACKGROUND

[0002] The heat dissipation fin is a core heat dissipation element in the fields of electronic equipment, new energy vehicles, industrial machinery, etc., and its performance directly affects the stability and service life of the equipment. Aluminum profiles are the preferred material for heat dissipation fins due to their high thermal conductivity, low density, and controllable cost. In the battery module of a new energy vehicle, the aluminum alloy heat dissipation fin controls the temperature difference of the battery within ±2℃ through dense fin design, ensuring the safety of fast charging.

[0003] However, during the extrusion molding process of aluminum profiles, burrs or shake marks are easily formed at the edges of the fins, grooves, and other parts due to mold elastic deformation, casting rod defects, or discontinuous metal flow. Such defects not only damage the surface finish but also reduce the heat dissipation efficiency. The contact thermal resistance caused by burrs can reduce the heat dissipation performance by 20%-30%, so deburring treatment is required. New heat dissipation fins not only include flat surfaces but also complex structures such as concave spherical grooves and convex spherical blocks.

[0004] The deburring equipment or tools in the prior art usually adopt rigid structures, such as monolithic flat scrapers and fixed curvature polishing heads, which can only adapt to a single type of surface. When facing complex structures such as concave spherical grooves and convex spherical blocks in heat dissipation fins, such tools either leave burrs due to shape mismatch or require manual replacement of different tools, significantly reducing efficiency and increasing cost. Although existing curved polishing equipment attempts to improve the fit through a floating mechanism, it still relies on fixed-shaped polishing heads and cannot dynamically adjust the shape to cover multiple curvature requirements. In view of this, we propose an aluminum profile surface burr finishing device. SUMMARY
