Description

Technical Field

[0001] The invention relates to a method for mirror-polishing a dark-colored blade surface of a cutting tool and the tool. Background Art

[0002] The blades of kitchen or outdoor knives, fish knives, daggers and other cutting knives on the market are generally sharpened with a conventional wrap angle of 35°, and the blade surface is sanded. Generally, the grinding belt or grinding wheel with a grinding number of 240# or 320# can meet the basic cutting function, but there are two obvious defects:

[0003] The combination of sanded blade surface and regular stainless steel original color surface cannot convey to buyers the concept of knife sharpness only from the appearance display, and whether a knife is sharp is precisely the primary goal of consumers' choice;

[0004] For conventional sanded blade surfaces and blades with an angle of about 35°, the initial sharpness and long-term sharpness (retention) of the product are not good.

[0005] Therefore, a method for mirror sharpening the dark blade surface of a cutting tool and a tool are provided. Summary of the invention

[0006] The purpose of the present invention is to overcome the existing defects and provide a method for mirror-polishing a dark blade surface of a cutting tool and a tool, thereby improving the sharpness and long-lasting sharpness of the tool.

[0007] The technical solution to achieve the above purpose is:

[0008] A method for mirror sharpening a dark-colored blade surface of a cutting tool according to one embodiment of the present invention comprises:

[0009] Step S1, the tool is pre-processed to make the tool surface appear light gray to black or even colorful;

[0010] Step S2, sharpening the cutting tool from coarse to fine using abrasives of different finenesses;

[0011] Step S3, after sharpening, use a leaf-leaf leather wheel, a soft leather wheel or a cotton cloth wheel in combination with polishing wax to remove the edge of the blade and polish the blade surface to a high-gloss mirror surface.

[0012] Preferably, in step S1, the pre-treatment of the tool includes: punching the tool, heat treating and polishing the surface.

[0013] Preferably, in step S1, before sharpening, the blade surface is subjected to one or more processes such as spraying, electrophoresis, coating, blackening, stone washing, so that the blade surface presents a light gray to black or even colorful tool surface.

[0014] Preferably, in step S2, the blade is sharpened twice or more times by using an abrasive belt, a grinding wheel or a CBN with a mesh size of 240#-1200# or even 2000# to produce a fine surface on the blade surface.

[0015] Preferably, in step S2, the sharpening body is manually sharpened with a sharpening machine, specifically:

[0016] Artificial combined grinding wheel sharpening machine: abrasive from coarse to fine, the process includes but is not limited to: 320# resin grinding wheel → 600# resin grinding wheel → 1200# resin grinding wheel;

[0017] Manual combination of disc sharpening machine and abrasive belt sharpening machine: abrasives from coarse to fine, the process includes but is not limited to: 320# resin grinding wheel → 600# resin grinding wheel → 1200# abrasive belt.

[0018] Preferably, in step S2, the blade sharpening body is a CNC automatic sharpening machine, specifically:

[0019] CNC automatic cutting machine: abrasive from coarse to fine, the process includes but is not limited to: 400# resin grinding wheel → 1200# resin grinding wheel.

[0020] Preferably, in step S3, the polishing wax is one or more of green, white, purple or red, including but not limited to the following:

[0021] Thousand-leaf leather wheel + white wax, polishing multiple times including 2-20 times;

[0022] Thousand-leaf leather wheel + green wax + white wax, polishing multiple times including 2-20 times;

[0023] Soft leather wheel + white wax, multiple polishing times include 2-20 times.

[0024] The second aspect of the present invention is a cutting tool made by a method for sharpening a dark blade surface of a cutting tool, comprising: a handle and a blade surface, wherein the blade surface is a surface that has been punched, heat treated and polished, and the blade surface is subjected to one or more processes such as spraying, electrophoresis, coating, blackening and stone washing to make the blade surface present a light grey to black or even colorful surface, and the blade is sharpened using abrasives of different finenesses from coarse to fine, and a thousand-leaf leather wheel, soft leather wheel or cotton cloth wheel combined with polishing wax is used to remove the burrs on the blade tip and polish the blade surface to a high gloss mirror surface.

[0025] Preferably, the blade surface of the knife surface is one of double-sided edge, single-sided edge or clam edge, or a combined edge of a V-shaped edge and a clam edge.

[0026] Preferably, the blade edge angles are: single-side angle 5°-20°, double-side angle 10°-40°; blade width: 0.5mm-5mm; blade thickness: 0.1-1mm.

[0027] The beneficial effects of the present invention are:

[0028] The invention uses a dark blade surface combined with a high-gloss mirror blade surface to give a strong visual impact and convey a feeling that the knife is extremely sharp.

[0029] This method improves the sharpness and sustained sharpness of the product. According to ISO8442-5 2005, the sharpness and sustained sharpness test shows that the initial sharpness reaches 138.6 and the sustained sharpness reaches 802.3, which are much higher than the initial sharpness > 50 and sustained sharpness > 150 required by ISO8442-5 2005, and much higher than the excellent requirements of initial sharpness > 110 and sustained sharpness > 550 in the sharpness grade requirements.

[0030] Through the mirror-finished blade sharpening method of the present invention, the blade tip is thinner, which reduces the cutting resistance, and the sharpening abrasive is fine enough, and the micro-serrations are denser and smaller, thereby dispersing the resistance during cutting, reducing the pressure of a single micro-serration, and improving the durability of the blade tip.

[0054] like Figure 5 As shown, one of the knives made by the method of mirror-polishing a dark blade surface of a cutting tool comprises: a handle 1 and a blade surface 2, wherein the blade surface 2 is a surface that has been punched, heat-treated and polished, and the surface of the blade surface 2 is subjected to one or more processes such as spraying, electrophoresis, coating, blackening, and stone washing to make the blade surface 2 present a light gray to black or even colorful surface, and the blade is sharpened from coarse to fine using abrasives of different finenesses, and a thousand-leaf leather wheel, soft leather wheel or cotton cloth wheel combined with polishing wax is used to remove the edge of the blade tip and polish the blade surface to a high-gloss mirror surface.

[0055] In the embodiment, the blade surface of the blade face 2 is one of double-sided edge, single-sided edge or clam edge, or a combination of V-shaped edge and clam edge.

[0057] The method for mirror sharpening the dark blade surface of a cutting tool mentioned in the present invention is described in detail through the following embodiments, but the specific parameters are modifiable and changeable.

[0058] Example 1

[0059] Step 1: After the blade surface is polished, spray black paint on the surface.

[0060] Step 2: Manually cooperate with the grinding wheel sharpening machine, and the sharpening abrasives are from coarse to fine: 240# resin grinding wheel - 600# resin grinding wheel - 1200# resin grinding wheel sharpening, the single-sided angle of the sharpening is 10°, and the double-sided angle (wrapped angle) is 20°.

[0061] Step 3: Use a thousand-leaf leather wheel and polishing wax to remove the burrs on the blade. Sweep the left and right sides of the blade 2-4 times each, for a total of 4-8 times or more on both sides, to make the blade surface reach a high-gloss mirror finish.

[0062] Example 2

[0063] Step 1: After the blade is polished, the surface is stone washed.

[0064] Step 2, use a CNC automatic sharpening machine, and the sharpening abrasives are from coarse to fine: 400# resin grinding wheel -1200# resin grinding wheel for sharpening, the single-sided angle of the sharpening is 7°, and the double-sided angle (wrapped angle) is 14°.

[0065] Step 3: Use a thousand-leaf leather wheel and polishing wax to remove the burrs on the blade. Sweep the left and right sides of the blade 2-4 times each, for a total of 4-8 times or more on both sides, until the blade surface reaches a high-gloss mirror finish.

[0066] Example 3

[0067] Step 1: After the blade is polished, the surface is titanium-plated to a black color.

[0068] Step 2: Manually cooperate with the grinding wheel sharpening machine and the water belt sharpening machine, and the sharpening abrasives are from coarse to fine: 240# resin grinding wheel - 600# resin grinding wheel - 1200# water belt sharpening, the single-sided angle of the sharpening is 10°, and the double-sided angle (wrapped angle) is 20°.

[0069] Step 3: Use a multi-layer leather wheel and polishing wax to remove the burrs on the blade. Sweep the left and right sides of the blade 2-4 times each, for a total of 4-8 times or more on both sides, to make the blade surface reach a high-gloss mirror finish.

[0070] Through the mirror-finished blade sharpening method of the present invention, the roughness of the high-gloss mirror blade surface is less than 0.05um, while the roughness of the conventional sanded blade surface is greater than 0.35um; finer roughness will reduce friction when cutting food, thereby improving sharpness and lasting sharpness and enhancing the user experience.

[0071] By using the mirror-finish blade sharpening method of the present invention, the blade tip thickness is thinner, so that the cutting resistance is smaller; Figure 2 It is the microscopic value of the blade tip thickness after mirror sharpening. The average blade tip thickness is 1.151um. The specific values ​​are shown in Table 1.

[0072]

[0073]

[0074] Table 1

[0075] Down Figure 3 It is the microscopic value of the blade tip thickness after sanding and sharpening. The average blade tip thickness is 3.706um. The specific values ​​are shown in Table 2.

[0076]

[0077] Table 2

[0078] The blade tip line is measured as a straight line. From a microscopic point of view, the blade tip is actually a micro-serration structure. Through the blade sharpening method of the present invention, the sharpening abrasive is fine enough, and the micro-serrations are denser and smaller, thereby dispersing the resistance during cutting, reducing the pressure of a single micro-serration, and improving the durability of the blade tip; as follows Figure 4 The micro-serrated structure shown.
