Light, sterilizing and light-emitting cutting tool high in bonding strength

Abstract

The invention discloses a light, sterilizing and light-emitting cutting tool high in bonding strength. The light, sterilizing and light-emitting cutting tool comprises a tool body and is characterized by further comprising a blade and lapping pieces; a threaded hole used for being connected with a drive device is formed in the rear end of the tool body; an inner thread is arranged in the threaded hole; the blade is arranged at the front end of the tool body; a plurality of weight reduction grooves are formed in the middle of the blade; the two lapping pieces are welded to the tool body; hooks are arranged at the free ends of the lapping pieces; two open grooves are formed in the rear end of the blade; the hooks of the lapping pieces can stretch into the corresponding open grooves of the blade for matched connection; a light source is arranged on the tool body; light rays generated by the light source are ultraviolet rays; a plurality of light guide pieces are arranged on the blade; the light source and the light guide pieces are located on the same straight line; the light guide pieces are perpendicular to a cutting edge, absorb the light rays emitted by the light source and guide the light rays to the cutting edge; and the blade is made of cemented titanium-tung-sten carbide.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a light-weight, bactericidal and luminescent cutting tool with high bonding strength. Background technique [0002] At present, the blades of cutting tools are made of high-speed steel materials, but the strength and wear resistance of high-speed steel materials are poor, which makes cutting tools very easy to damage during use, which increases the burden on enterprises and brings greater losses to enterprises. . At the same time, when the cutting tool is cutting steel, due to the diffusion reaction between the tool and the chips at the cutting temperature, the cutting tool is very prone to crater wear, which further reduces the service life. At the same time, the overall quality of the current blade is relatively large, which affects the use of the cutter, and is made of tungsten-titanium-cobalt cemented carbide, and the cost is also high. In addition, the bonding strength between the blade a...

[0002] At present, the blades of cutting tools are made of high-speed steel materials, but the strength and wear resistance of high-speed steel materials are poor, which makes cutting tools very easy to damage during use, which increases the burden on enterprises and brings greater losses to enterprises.

At the same time, when the cutting tool is cutting steel, due to the diffusion reaction between the tool and the chip at the cutting temperature, the cutting tool is very prone to crater wear, which further reduces the service life

At the same time, the overall quality of the current blade is relatively large, which affects the use of the tool, and is made of tungsten-titanium-cobalt cemented carbide, and the cost is also high

In addition, the bonding strength between the blade and the tool body is not enough, which often easily causes damage to the blade and brings great losses to the enterprise.

At the same time, at present, bacteria are quite easy to remain on the knives, causing the hygienic quality of the knives to be considered, which will also have an adverse effect on the production and processing of the aseptic workshop, and the current knives cannot emit light, so when the light is dark, the operator cannot It is better to use knives, and there are certain safety hazards, which have a greater impact on the operation
