Description

Technical Field

[0001] This utility model belongs to the technical field of rotary cutting tool processing, specifically relating to an anti-splash device for air knife used in rotary cutting tool processing. Background Technology

[0002] A cladding machine for veneer cutting is a specialized piece of equipment based on laser cladding or plasma cladding technology. It is primarily used for strengthening, repairing, and coating the cutting edges of veneer cutting tools (such as wood veneer cutting tools and metal veneer cutting tools). By cladding a layer of high-performance alloy (such as wear-resistant, corrosion-resistant, and high-temperature-resistant materials) onto the cutting edge of the veneer cutting tool, the tool's lifespan, cutting efficiency, and machining accuracy can be significantly improved, while reducing production costs.

[0003] Specifically, during the laser cladding process of a rotary cutter, due to the characteristics of the cladding process, the intense metallurgical reaction in the high-temperature molten pool generates a large amount of weld slag spatter and metallic fumes. These weld slag particles easily adhere to the surface of the optical lenses of the laser cladding head, leading to a decrease in lens transmittance and a reduction in beam energy. The metallic fumes contain vaporized alloying elements and tiny particles, which not only condense on the lens surface to form a contamination film, reducing laser focusing accuracy, but may also enter the precision components inside the cladding head, accelerating mechanical wear. This, in turn, affects the surface quality, density, and bonding strength of the cladding layer with the substrate, ultimately resulting in the rotary cutter failing to meet processing accuracy and wear resistance standards, increasing equipment maintenance costs and downtime for repairs. Utility Model Content
