Preparation method and device of scale-like multifunctional surface microstructure

Abstract

The invention discloses a preparation method and device of a fish scale-like multifunctional surface microstructure. Existing workpiece surface wear resistance needs to be improved. According to the method, a special coulter head is adopted to manufacture a ploughing cutter, and then the ploughing cutter is used for machining a plurality of rows of fish scale type microstructures on the to-be-machined surface of a workpiece, wherein the fish scale type microstructure is composed of a plurality of arc-shaped sheets which are connected in sequence; then, carbon fiber powder is sprayed into all rows of fish scale type microstructures through a carbon fiber powder spray head; and finally, all the fish scale type microstructures are rolled through a rolling roller to form the final fish scale-like multifunctional surface microstructure. The fish scale-like multifunctional surface microstructure machined on the surface of the workpiece achieves load reduction and resistance reduction of the workpiece, efficient heat dissipation and adhesion prevention, and has the wear-resistant characteristic.

Description

technical field [0001] The invention belongs to the technical field of functional microstructures, and in particular relates to a method and device for preparing multifunctional fishscale-like microstructures with high hardness surfaces such as knives. Background technique [0002] Cutting tools are very important tools in machining and are widely used in various preparation and processing links in the manufacturing industry. All aspects of the performance of the tool will directly affect the quality of the product produced. During the machining process, friction, adhesion, heat, etc. will cause the tool to fail, thereby reducing production efficiency. However, bionics has proved that a high-performance structure with a certain non-smooth shape can exert good properties such as wear resistance, anti-adhesion, and high-efficiency heat dissipation. Due to the excellent characteristics of the bionic functional structure, it can be set on the rake face and flank face of the tool...
