Embodiment 1

[0032] Such as figure 1 and 2 As shown, Embodiment 1 provides a blade structure, which includes a knife body 1 and a composite material layer 2, and the composite material layer 2 is arranged on one side of the knife body 1, that is, the composite material layer 2 and the knife body 1 are laminated or In the laminated structure, the composite material layer 2 and the knife body 1 form an integrated structure through three times of high-temperature fusion, the surface of the composite material layer 2 is uneven and concave-convex, and the thickness of the composite material layer 2 is 20-30 microns.

[0033] Through the composite material fusion process, the knife body 1 and the composite material layer 2 are fused together to form a very strong fusion layer. This fusion layer with composite materials has extremely high hardness and wear resistance. Due to the composite The material layer 2 is laminated with the knife body 1, and the welded layer is always at the cutting edge ...

Embodiment 2

[0040] Such as image 3 As shown, Embodiment 2 provides a method for manufacturing the blade structure, which is used to manufacture the blade structure in Embodiment 1. The method includes the following five steps.

[0041] Step 1. Sharpen the blade. For the knife body that has been heat-treated and tempered, a beveled edge with an edge angle of 10-15° is formed on one side of the knife body, so that the beveled edge is 3-5mm, and the beveled edge is used as a fusion surface, and the other side is It can be sharpened according to the conventional cutting method.

[0042] Step 2. Preset materials. A layer of composite material particles is preset on the slope of the cutting edge, and the thickness of the preset composite material particles is 80-120 microns.

[0043] Step 3, sintering. Use the sintering equipment to sinter the bevel of the cutting edge pre-prepared with composite material particles for three times, which can make the bevel of the cutting edge and the compo...

Embodiment 3

[0050] Embodiment 3 provides a kitchen knife, including a knife body and a knife handle fixed to the knife body, characterized in that a composite material layer is provided on one side of the knife body, and the composite material layer and the knife body are integrated by three times of high-temperature sintering structure, the surface of the composite material layer is uneven and concave-convex, and the thickness of the composite material layer is 20-30 microns.

[0051] Through the composite material fusion process, the knife body and the composite material layer are fused together to form a very strong fusion layer. This fusion layer with composite material has extremely high hardness and wear resistance. Due to the composite material layer It is laminated with the knife body, and the welding layer is always on the cutting edge, so that one side of the knife body at the cutting edge is protected by a composite material layer, which improves the wear resistance of the cutti...

Abstract

Relating to the technical field of cutters, the embodiment of the invention discloses a cutting edge structure, a manufacturing method of the cutting edge structure and a kitchen knife. The cutting edge structure comprises a cutter body and a composite material layer, the composite material layer is arranged on one side face of the cutter body, the composite material layer and the cutter body forman integral structure through three times of high-temperature sintering, the surface of the composite material layer is in an uneven concave-convex shape, and the thickness of the composite materiallayer is 20-30 micrometers. The cutting edge structure provided by the embodiment of the invention integrally has the advantages of high wear resistance, high cutting performance, high toughness and high hardness.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of knives, and in particular to a blade structure, a method for manufacturing the blade structure, and a kitchen knife. Background technique [0002] A kitchen knife is a tool used to process ingredients during cooking. It is mainly used for chopping and cutting. The blade must be hard enough and thin enough, but also tough enough to withstand the force without breaking, otherwise it will collapse and curl. The mouth also requires high wear resistance to avoid unsharpness. [0003] The hardness of existing kitchen knives is generally around HRC 58-65. If the hardness continues to increase, it is easy to break or chip, and the toughness and rigidity of the blade cannot be well combined. And existing kitchen knives, the cutting ability of blade is relatively poor, if the ultra-thin of blade polishing, can improve the degree of sharpness, but can reduce wear resistance and service lif...
