Knife structure with side serrations and manufacturing process therefor

Abstract

The present invention relates to the technical field of knives, and specifically relates to a knife structure with side serrations and a manufacturing process therefor, to ensure the strength and impact resistance of a knife body, preventing the blade thereof from easily rolling or chipping during chopping and mincing, thus making it suitable for cutting and chopping. Strip-shaped side serrations have a pulsed compression effect on food ingredients; and the fluctuation generated when pulling the strip-shaped serrations back and forth accelerates the transverse splitting of the food ingredients, forcing the food ingredients to tear apart on two sides perpendicular to the direction of cutting; thus, cutting force that acts on the blade is reduced, providing protection for the blade, and thereby extending the durability of the sharpness of the blade. After being used for a period of time, the blade wears off upwards, such that the strip-shaped serrations are exposed, enabling the blade to still maintain good cutting performance; in addition, a user can restore the blade into the original state of having a cutting edge through sharpening. Thus, the present invention effectively solves the technical problem in the prior art of a serrated knife being unable to chop and mince, unsuitable for peeling, and difficult to sharpen.

Description

A tool structure with side tooth grooves and its manufacturing process Technical Field

[0001] The present invention relates to the technical field of cutting tools, and more particularly to a cutting tool structure with side tooth grooves and a manufacturing process thereof. Background Art

[0002] Sharpness and sharpness retention are two very important properties of knives. The higher the sharpness, the easier it is to cut food. The higher the sharpness retention, the longer the knife remains sharp, and the time interval between sharpening is correspondingly longer. In order to improve these two indicators, the most commonly used solution is to use higher-quality materials. For example, by increasing the carbon and chromium content to increase the hardness of the knife, thereby improving cutting performance. However, high-quality materials often lead to increased costs, and the performance improvement is relatively limited. Another idea is to change the structure of the knife. For example, make the kitchen knife into a "saw"-like blade. Through the undulating blade edge, the cutting distance and shear force of the food are enhanced, making it easier to cut.

[0003] For example, the prior art provides a kitchen knife with strip-shaped tooth grooves, comprising a knife body and a handle, wherein the top of one side of the knife body is fixedly connected to the handle via a connecting rod, the bottom of the knife body is provided with a strip-shaped groove, the bottom of the knife body is provided with a blade, the top of the blade is fixedly connected to a clamping block adapted to the groove, the bottom of the front of the knife body is provided with three evenly distributed I-shaped through-grooves, and the I-shaped through-grooves on the knife body are flush with the grooves and the clamping block, the internal movable sleeve of the I-shaped through-grooves on the knife body is provided with a fixing bolt, and the external thread of one end of the fixing bolt is provided with a fastening nut, and the bottom of the blade is provided with evenly distributed strip-shaped tooth grooves. This solution adds a sawtooth shape to the blade, which can still effectively cut objects after long-term use. After adding the sawtooth structure, the function of strip-shaped tooth groove cutting is realized, improving cutting performance while achieving easier cutting.

[0004] However, in knives of the prior art, the serrations are located on the blade, and this structure limits the application of serrations on kitchen knives. The material volume at the blade is less than that of an ordinary blade, resulting in low strength and weak impact resistance. The blade is prone to curling or chipping during chopping and chopping. Moreover, the blade is not a straight line and is not suitable for cutting food. At the same time, due to the special shape of the serrated blade, it is difficult for ordinary users to restore the edge to its original state by grinding it after it is worn. Therefore, the serrated knives of the prior art have technical problems such as being unable to be used for chopping and chopping, being unsuitable for slicing, and being difficult to grind.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings of serrated tools in the prior art, such as being unable to be used for chopping and cutting, being unsuitable for slicing, and being difficult to sharpen, and to provide a tool structure with side tooth grooves and a manufacturing process thereof.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A tool structure with side tooth grooves includes a tool body and a handle with one end connected to the top of the side of the tool body. A blade is provided at the bottom of the tool body. A smooth inclined surface is formed between the blade and the blade surface on one side of the tool body. The tool body is vertically provided with a plurality of strip tooth grooves on the smooth inclined surface. The plurality of strip tooth grooves are evenly arranged above the blade along the direction of the blade. The dividing line between the smooth inclined surface and the blade surface is between the upper end and the lower end of the strip tooth groove.

[0009] The present invention provides a tool structure with side tooth grooves. Since the strip tooth grooves are arranged on the smooth inclined surface between the blade and the blade surface, and the boundary line between the smooth inclined surface and the blade surface is between the upper end and the lower end of the strip tooth groove, the smooth inclined surface is an inclined surface formed by the blade surface shrinking and transitioning in the direction of the cutting edge of the blade. Therefore, the arrangement position of several strip tooth grooves is close to the position of the blade, which will not reduce the material at the blade, thereby ensuring the strength and impact resistance of the tool body, and will not easily cause edge curling or chipping during chopping and chopping. Since the blade still maintains an ordinary straight line, it is suitable for cutting and chopping. Since the strip tooth grooves are only arranged on the smooth inclined surface on one side of the tool body, which side is the right side for right-handed users or the left side for left-handed users, it is also That is, the side close to the food being cut. When the blade cuts into the food and cuts back and forth, the strip-shaped tooth grooves on the side have a pulsed squeezing effect on the food. The ups and downs generated when sawing the strip-shaped tooth grooves accelerate the lateral splitting of the food, forcing the food to be torn on both sides perpendicular to the cutting direction, reducing the cutting force acting on the blade, and protecting the blade, thereby prolonging the sharpness of the blade. After a period of use, the blade wears upward and the strip-shaped tooth grooves begin to appear, so that the blade still has good cutting performance, and the user can restore it to its original edge state by grinding, which effectively solves the technical problems in the existing technology that serrated tools cannot be used for chopping and chopping, are not suitable for cutting, and are difficult to grind.

[0010] Furthermore, the distance between the lower end of the strip-shaped tooth groove and the blade is 0.2mm-2mm. Setting the distance between the lower end of the strip-shaped tooth groove and the blade to 0.2mm-2mm effectively maintains the straight shape and strength of the blade, ensuring the blade's cutting and chopping functions while exerting a pulse-like squeezing effect on food.

[0011] Furthermore, the distance from the upper end to the lower end of the strip-shaped tooth groove is 2mm-5mm. The length of the strip-shaped tooth groove is set to 2mm-5mm. Within this value range, the longitudinal contact between the strip-shaped tooth groove and the food can stably apply a lateral force to the food.

[0012] Furthermore, the width of the strip-shaped tooth groove is 0.1mm-0.8mm. Setting the width of the strip-shaped tooth groove to 0.1mm-0.8mm ensures that the undulating effect generated when the strip-shaped tooth groove is sawed can maximize the force to tear the food on both sides perpendicular to the cutting direction.

[0013] Furthermore, the depth of the strip-shaped tooth groove is 0.04 mm to 0.4 mm. The depth of the strip-shaped tooth groove is set to 0.04 mm to 0.4 mm to ensure that the contact force between the strip-shaped tooth groove and the food in the cutting direction remains perpendicular to the cutting direction.

[0014] Furthermore, the center spacing between the plurality of strip-shaped tooth grooves is 0.1 mm-1 mm. The center spacing between the plurality of strip-shaped tooth grooves is set to 0.1 mm-1 mm, so that the period of the undulation generated when the strip-shaped tooth grooves are sawed can play an optimal pulse-type extrusion role.

[0015] Furthermore, the angle formed by the smooth bevel and the blade surface is 15°-25°. The angle formed by the smooth bevel and the blade surface is 15°-25° to ensure the sharpness of the blade.

[0016] Furthermore, the angle formed between the slotting direction of the strip-shaped tooth groove and the blade surface is 30°-60°. Setting the angle formed between the slotting direction of the strip-shaped tooth groove and the blade surface to 30°-60° can achieve labor-saving and efficient cutting effects at multiple cutting angles.

[0017] Furthermore, the thickness of the tool body is 3mm-5mm. The thickness of the tool body is 3mm-5mm to ensure that the tool body has sufficient strength for cutting and chopping.

[0018] The present invention also provides a process for manufacturing a tool structure having side tooth grooves, comprising the following steps:

[0019] S1. Prepare a 5Cr15MoV steel plate for leveling;

[0020] S2. Using a laser cutting machine, the steel plate after the leveling process in step S1 is cut into 3mm-5mm thick tool bodies at a cutting speed of 1000mm / min-1100mm / min;

[0021] S3. The tool body is sequentially quenched and tempered, the blade is heated to 1000 ℃ -1060 ℃, held for 10min, and then quenched with oil, then heated to 200 ℃, held for 3 hours, and finally cooled to room temperature to complete the tempering;

[0022] S4. Using a CNC water mill, the blade surface of the tool body on one side is plane-ground, followed by rough grinding and fine grinding, and finally opening a smooth bevel at the bottom of the blade surface on this side, the angle formed by the smooth bevel and the blade surface is 15 ° -25 °, and finally the blade surface is water-polished;

[0023] S5. Fix the tool body with a fixture and use a grinding wheel to grind a row of strip-shaped troughs on the smooth inclined surface, so that the boundary line between the smooth inclined surface and the blade surface is between the upper and lower ends of the strip-shaped troughs, the distance from the upper end to the lower end of each strip-shaped trough is 2mm-5mm, the width is 0.1mm-0.8mm, and the depth is 0.04mm-0.4mm. The center spacing between adjacent strip-shaped troughs is 0.1mm-1mm, and the angle formed by the groove direction of the strip-shaped troughs and the blade surface is 30°-60°;

[0024] S6. Paste a plastic protective film on the blade surface on both sides of the tool body, install the handle and the tool body, and polish the handle;

[0025] S7. Remove the plastic protective film, use a CNC machine to sharpen the bottom of the tool body to obtain the blade, grind the ends of several strip-shaped tooth grooves close to the blade to be in a straight line, and the distance between the lower end of the strip-shaped tooth groove and the blade is 0.2mm-2mm.

[0026] The present invention relates to a manufacturing process of a tool structure with side tooth grooves. In step S1, the 5Cr15MoV material used is martensitic stainless steel, which has the advantages of high hardness and high strength. The steel plate after flattening has higher flatness, which is convenient for subsequent processing. In step S2, a laser cutting machine is used to cut the steel plate into 3mm-5mm thick pieces. The tool body has sufficient strength for cutting and chopping. The cutting speed of 1000mm / min-1100mm / min can effectively protect the surface strength of the tool body. In step S3, the tool body is sequentially quenched and tempered to stabilize the metallographic structure in the tool body, thereby stabilizing the tool body. The size and shape of the body are improved to improve the cutting and chopping performance of the tool body; step S4 uses a CNC water grinder to plane-grind the blade surface on one side of the tool body, performs coarse grinding and fine grinding in sequence, and finally opens a smooth bevel at the bottom of the side blade surface, so that the angle formed by the smooth bevel and the blade surface is 15°-25° to ensure the sharpness of the subsequent blade sharpening, and finally performs water grinding and polishing on the blade surface to improve the surface corrosion resistance of the tool body; step S5 uses a grinding wheel to grind a row of strip-shaped tooth grooves on the smooth bevel, so that the boundary line between the smooth bevel and the blade surface is between the upper end and the lower end of the strip-shaped tooth groove, and the distance from the upper end to the lower end of each strip-shaped tooth groove is 2 The tooth grooves are 0.1-1.5mm thick, 0.1-0.8mm wide, 0.04-0.4mm deep, and the center spacing between adjacent strip-shaped tooth grooves is 0.1-1mm. The angle formed by the slotting direction of the strip-shaped tooth grooves and the blade surface is 30°-60°, ensuring that the longitudinal contact between the strip-shaped tooth grooves and the food can stably exert a lateral force on the food. The undulating effect generated when sawing the strip-shaped tooth grooves can force the food to tear on both sides perpendicular to the cutting direction to the maximum extent, so that the contact surface force between the strip-shaped tooth grooves and the food in the cutting direction is kept perpendicular to the cutting direction, ensuring that the period of the undulating fluctuations generated when sawing the strip-shaped tooth grooves can play a role. The optimal pulse extrusion effect enables the tool body to achieve labor-saving and efficient cutting effects at multiple cutting angles; step S6 sticks plastic protective film on the blade surfaces on both sides of the tool body to prevent the polishing of the handle from affecting the blade surface of the tool body; step S7 uses a CNC machine to sharpen the bottom of the tool body to obtain the blade, and grinds the ends of several strip-shaped tooth grooves close to the blade into a straight line, so that the distance between the lower end of the strip-shaped tooth groove and the blade is 0.2mm-2mm, effectively maintaining the straight shape and strength of the blade, and ensuring the cutting and chopping functions of the blade while exerting a pulse-like extrusion effect on the food.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention provides a tool structure with side tooth grooves, in which the arrangement position of several strip tooth grooves is close to the position of the blade, which will not reduce the material at the blade, ensure the strength and impact resistance of the tool body, and is not prone to curling or chipping when chopping and chopping; since the blade still maintains an ordinary straight line, it is suitable for cutting and chopping, and when the blade cuts into the food and cuts back and forth, the side strip tooth grooves have a pulsed extrusion effect on the food, and the ups and downs generated when the sawing strip tooth grooves accelerate the lateral splitting of the food, forcing the food to be torn on both sides perpendicular to the cutting direction, reducing the cutting force acting on the blade, playing a role in protecting the blade, and thus prolonging the sharpness retention of the blade; after a period of use, the blade wears upward and the strip tooth grooves begin to appear, so that the blade still has good cutting performance, and the user can restore it to the original cutting edge state by grinding, effectively solving the technical problems in the prior art that serrated tools cannot be used for chopping and chopping, are not suitable for cutting, and are difficult to grind.

[0029] The present invention provides a manufacturing process for a tool structure with side tooth grooves. Quenching and tempering treatments stabilize the metallographic structure within the tool body, thereby stabilizing the size and shape of the tool body and improving the cutting and chopping performance of the tool body. Water grinding and polishing treatment improves the surface corrosion resistance of the tool body. Polishing treatment of the handle improves the comfort of use of the handle.

[0036] Example 1

[0037] FIG. 1 and FIG. 2 show a first embodiment of a tool structure with side tooth grooves according to the present invention.

[0038] A tool structure with side tooth grooves includes a tool body 1 and a handle 2 connected to the top of the side of the tool body 1 at one end. A blade 11 is provided at the bottom of the tool body 1. A smooth inclined surface 13 is formed between the blade 11 and a blade surface 12 on one side of the tool body 1. The tool body 1 has a plurality of strip-shaped tooth grooves 14 vertically opened on the smooth inclined surface 13. The plurality of strip-shaped tooth grooves 14 are evenly arranged above the blade 11 along the direction of the blade 11. The dividing line between the smooth inclined surface 13 and the blade surface 12 is between the upper and lower ends of the strip-shaped tooth grooves 14.

[0039] In this embodiment, as shown in Figures 1 to 2, since the strip-shaped tooth grooves 14 are arranged on the smooth inclined surface 13 between the blade 11 and the blade surface 12, and the boundary line between the smooth inclined surface 13 and the blade surface 12 is between the upper end and the lower end of the strip-shaped tooth grooves 14, the smooth inclined surface 13 is an inclined surface formed by the blade surface 12 shrinking and transitioning toward the cutting edge of the blade 11. Therefore, the arrangement position of several strip-shaped tooth grooves 14 is close to the position of the blade 11, which will not reduce the material at the blade 11, thereby ensuring the strength and impact resistance of the tool body 1, and is not prone to edge curling or chipping during chopping and chopping; since the blade 11 still maintains an ordinary straight line, it is suitable for cutting and chopping; since the strip-shaped tooth grooves 14 are only provided on the smooth inclined surface 13 on one side of the tool body 1, this side is the right side of a right-handed user or the left-handed user On the left side, that is, the side close to the cut food, when the blade 11 cuts into the food and cuts back and forth, the strip-shaped tooth grooves 14 on the side have a pulsed squeezing effect on the food. The ups and downs generated when sawing the strip-shaped tooth grooves 14 accelerate the lateral splitting of the food, forcing the food to be torn on both sides perpendicular to the cutting direction, reducing the cutting force acting on the blade 11, and protecting the blade 11, thereby prolonging the sharpness retention of the blade 11; after a period of use, the blade 11 wears upward, and the strip-shaped tooth grooves 14 begin to appear, so that the blade 11 still has good cutting performance, and the user can restore it to its original cutting edge state by grinding, which effectively solves the technical problems in the prior art that serrated tools cannot be used for chopping and chopping, are not suitable for cutting, and are difficult to grind.

[0042] This embodiment is similar to the first embodiment, except that: the distance between the lower end of the strip-shaped tooth groove 14 and the blade 11 is 0.2mm-2mm. The distance from the upper end to the lower end of the strip-shaped tooth groove 14 is 2mm-5mm. The width of the strip-shaped tooth groove 14 is 0.1mm-0.8mm. The depth of the strip-shaped tooth groove 14 is 0.04mm-0.4mm. The center spacing between a plurality of strip-shaped tooth grooves 14 is 0.1mm-1mm. The angle formed by the smooth inclined surface 13 and the blade surface 12 is 15°-25°. The angle formed by the slotting direction of the strip-shaped tooth groove 14 and the blade surface 12 is 30°-60°. The thickness of the tool body 1 is 3mm-5mm.

[0043] In this embodiment, the distance between the lower end of the strip-shaped tooth groove 14 and the blade 11 is set to 1 mm. This spacing value can effectively maintain the straight shape and strength of the blade 11, and exert a pulse-like squeezing effect on the food while ensuring the cutting and chopping functions of the blade 11.

[0044] In this embodiment, the length of the strip-shaped tooth groove 14 is set to 3 mm. The longitudinal contact between the strip-shaped tooth groove 14 and the food can stably apply a lateral force to the food.

[0045] In this embodiment, the width of the strip-shaped tooth groove 14 is set to 0.4 mm to ensure that the undulating effect generated when the strip-shaped tooth groove 14 is sawed can force the food to be torn on both sides perpendicular to the cutting direction to the maximum extent.

[0046] In this embodiment, the depth of the strip-shaped tooth groove 14 is set to 0.2 mm to ensure that the contact force between the strip-shaped tooth groove 14 and the food in the cutting direction remains perpendicular to the cutting direction.

[0047] In this embodiment, the center intervals between the plurality of strip-shaped tooth grooves 14 are set to 0.5 mm, so that the period of the undulating fluctuations generated when the strip-shaped tooth grooves 14 are sawed can achieve the best pulse-type extrusion effect.

[0048] In this embodiment, the angle formed by the smooth inclined surface 13 and the blade surface 12 is 20° to ensure the sharpness of the blade 11.

[0049] In this embodiment, the angle formed by the slotting direction of the strip-shaped tooth groove 14 and the blade surface 12 is set to 45°, which can achieve a labor-saving and efficient cutting effect.

[0050] In this embodiment, the thickness of the tool body 1 is set to 4 mm to ensure that the tool body 1 has sufficient strength for cutting and chopping.

[0051] In addition, as shown in FIG3 , in this embodiment, the tool structure of the second embodiment is tested using the ISO 8442-5 2004 national standard sharpness test method. The tool structure is mounted on a tool sharpness tester. The cutting performance of the blade 11 is tested by clamping a wear-accelerating medium on the tool sharpness tester, applying a certain pressure to cut with the tested tool, and measuring the cutting depth of each cutting cycle to determine the sharpness of the tool. The final sharpness test results are shown in FIG3 .

[0065] Example 3

[0066] This embodiment is an embodiment of a manufacturing process of a tool structure with side tooth grooves of the present invention.

[0067] A manufacturing process of a tool structure with side tooth grooves comprises the following steps:

[0068] S1. Prepare a 5Cr15MoV steel plate for leveling;

[0069] S2. Use a laser cutting machine to cut the steel plate after the leveling process in step S1 into a tool body 1 with a thickness of 3mm-5mm at a cutting speed of 1000mm / min-1100mm / min;

[0070] S3. The tool body 1 is sequentially quenched and tempered, the blade is heated to 1000 ℃ -1060 ℃, held for 10min, and then quenched with oil, then heated to 200 ℃, held for 3 hours, and finally cooled to room temperature to complete the tempering;

[0071] S4. Using a CNC water mill, the blade surface 12 on one side of the tool body 1 is plane-ground, followed by rough grinding and fine grinding, and finally opening the smooth bevel 13 at the bottom of the side blade surface 12, the angle formed by the smooth bevel 13 and the blade surface 12 is 15 ° -25 °, and finally the blade surface 12 is water-polished;

[0072] S5. Fix the tool body 1 with a fixture and use a grinding wheel to grind a row of strip-shaped tooth grooves 14 on the smooth bevel 13. The boundary line between the smooth bevel 13 and the blade surface 12 is between the upper and lower ends of the strip-shaped tooth grooves 14. The distance from the upper end to the lower end of each strip-shaped tooth groove 14 is 2mm-5mm, the width is 0.1mm-0.8mm, and the depth is 0.04mm-0.4mm. The center spacing between adjacent strip-shaped tooth grooves 14 is 0.1mm-1mm. The angle formed by the slotting direction of the strip-shaped tooth grooves 14 and the blade surface 12 is 30°-60°.

[0073] S6. Paste a plastic protective film on the blade surface 12 on both sides of the tool body 1, install the handle 2 and the tool body 1, and polish the handle 2;

[0074] S7. Remove the plastic protective film and use a CNC machine to sharpen the bottom of the tool body 1 to obtain the blade 11. Grind the ends of the several strip-shaped tooth grooves 14 close to the blade 11 until they are in a straight line. The distance between the lower end of the strip-shaped tooth groove 14 and the blade 11 is 0.2mm-2mm.

[0075] In this embodiment, as shown in the figure, the 5Cr15MoV material used in step S1 is martensitic stainless steel, which has the advantages of high hardness and high strength. The steel plate after flattening has higher flatness, which is convenient for subsequent processing; step S2 uses a laser cutting machine to cut the steel plate into 3mm-5mm thick tool bodies 1 with sufficient strength for cutting and chopping, and a cutting speed of 1000mm / min-1100mm / min can effectively protect the surface strength of the tool body 1; step S3 performs quenching and tempering treatments on the tool body 1 in sequence to stabilize the metallographic structure in the tool body 1, thereby stabilizing the size and shape of the tool body 1 and improving the cutting performance of the tool body 1. The performance of cutting and chopping; Step S4 uses a CNC water grinder to plane-grind the blade surface 12 on one side of the tool body 1, performs rough grinding and fine grinding in sequence, and finally opens a smooth bevel 13 at the bottom of the side blade surface 12, so that the angle formed by the smooth bevel 13 and the blade surface 12 is 15 ° -25 °, ensuring the sharpness of the subsequent blade 11, and finally performs water-grinding polishing on the blade surface 12 to improve the surface corrosion resistance of the tool body 1; Step S5 uses a grinding wheel to grind a row of strip-shaped tooth grooves 14 on the smooth bevel 13, so that the boundary line between the smooth bevel 13 and the blade surface 12 is between the upper end and the lower end of the strip-shaped tooth groove 14, and the distance from the upper end to the lower end of each strip-shaped tooth groove 14 is 2mm-5mm The width is 0.1mm-0.8mm, the depth is 0.04mm-0.4mm, the center interval between adjacent strip-shaped tooth grooves 14 is 0.1mm-1mm, and the angle formed by the slotting direction of the strip-shaped tooth grooves 14 and the blade surface 12 is 30°-60°, ensuring that the longitudinal contact between the strip-shaped tooth grooves 14 and the food can stably apply a lateral force to the food. The undulating effect generated when the strip-shaped tooth grooves 14 are pulled and sawed can maximize the force of the food torn on both sides perpendicular to the cutting direction, so that the contact surface force between the strip-shaped tooth grooves 14 and the food in the cutting direction is kept perpendicular to the cutting direction, ensuring that the period of the undulating fluctuations generated when the strip-shaped tooth grooves 14 are pulled and sawed can play an optimal role. The pulse extrusion effect enables the tool body 1 to achieve labor-saving and efficient cutting effects at multiple cutting angles; step S6 sticks plastic protective film on the blade surface 12 on both sides of the tool body 1 to prevent the polishing of the handle 2 from affecting the blade surface 12 of the tool body 1; step S7 uses a CNC machine to sharpen the bottom of the tool body 1 to obtain a blade 11, and grinds the ends of several strip-shaped tooth grooves 14 close to the blade 11 to be in a straight line, so that the distance between the lower end of the strip-shaped tooth groove 14 and the blade 11 is 0.2mm-2mm, effectively maintaining the straight shape and strength of the blade 11, and ensuring the cutting and chopping functions of the blade 11 while playing a pulse-like extrusion effect on the food.
