A method of manufacturing an anti-rolling blade type knife

Abstract

The invention relates to an anti-blade coiling type cutter and a manufacturing method thereof. The anti-blade coiling type cutter comprises a cutting layer, a clamping layer and a supporting layer, wherein the cutting layer is positioned on the middle part of an axis of the cutter; the clamping layer is positioned on the outer part of the cutting layer; the hardness of the clamping layer is greater than that of the cutting layer; the clamping layer is arranged on the middle part of the cutting layer; the supporting layer comprises a U-shaped supporting plate arranged on the middle part of the cutting layer; the U-shaped supporting plate is embedded into the cutting layer; a cutting blade of the cutter is positioned at an opening end, corresponding to the U-shaped supporting plate, of the cutting layer; a vertical hole is formed in each of the clamping layer and the cutting layer; the U-shaped supporting plate is fixed in the cutting layer through a dowel which is fixed in one vertical hole. Due to the fact that the surface is relatively high in hardness and better in rigidity, higher mounting precision can be realized; meanwhile, the hardness of the cutting edge of the cutter is relatively low in hardness, the cutter is easier to grind; under the support of the outer surface of the cutter with relatively high hardness, certain cutting force can be kept, and the phenomena of deformation and the like are not caused by low hardness.

Description

technical field [0001] The invention relates to an anti-rolling edge cutter and a manufacturing method thereof, belonging to the field of cutters for machine tools. Background technique [0002] At present, cutting tools for cutting stainless steel materials have high strength requirements. Due to the cutting waste heat generated by the continuous friction between the tool and stainless steel materials, the cutting edge is bonded, the tool is severely worn, work hardening occurs, and edge formation is easy to occur. It is not easy to break chips. These factors will affect the cutting accuracy and service life of ordinary tools. At the same time, ordinary tools cannot cut stainless steel with high speed and high quality. In the prior art, hard coatings are often applied on the cutting tools by physical deposition and chemical deposition. This method can improve the strength, hardness, friction and wear resistance and service life of the cutting tools to a certain extent. Howe...
