Description

Technical Field

[0001] The invention belongs to the technical field of burr trimming, and provides a trimming mechanism for realizing automatic loading and unloading of aluminum profiles, accurately correcting burrs on the ends of aluminum profiles, and precisely controlling the turning process, and in particular relates to a burr trimming mechanism on the surface of the ends of aluminum profiles. Background Art

[0002] Aluminum profiles have been widely used in many fields such as construction, automobiles, aerospace, etc. due to their excellent properties such as light weight, high strength and corrosion resistance. During the processing of aluminum profiles, burrs often appear on the end surface of aluminum profiles due to the limitations of processing techniques such as cutting and sawing. These burrs not only affect the appearance quality of the aluminum profiles, but may also cause scratches, wear and other problems in subsequent processing and assembly, and even affect the overall performance and service life of aluminum profile products.

[0003] At present, the main methods for correcting burrs on the surface of aluminum profile ends are manual grinding and mechanical processing. Although manual grinding can remove burrs to a certain extent, it has problems such as high labor intensity, low production efficiency, and unstable processing quality. Traditional mechanical processing methods, such as using sanding machines, milling cutters, etc. for burr correction, although production efficiency has been improved, it is often difficult to achieve comprehensive and accurate burr correction for aluminum profile ends with complex shapes, and it is easy to leave processing marks on the surface of the aluminum profile, affecting the appearance and performance of the product.

[0004] In addition, most of the existing aluminum profile end burr correction equipment has a single function and cannot simultaneously meet the various processing requirements of aluminum profile loading and unloading, cleaning, and flipping force control.
