Description

Be suitable for high sharpness kitchen knife of high wear-resisting material

Technical Field

The utility model relates to a high sharpness kitchen knife suitable for high wear-resisting material.

Background

The kitchen knife is one of kitchen utensils, and is mainly used for cutting meat and vegetables. The strength, sharpness and smoothness of cutting are important parameters for considering the quality of a kitchen knife. Wherein the greater the angle of the blade tip, the higher the strength but the lower the sharpness; the smaller the angle, the higher the sharpness and the lower the strength. The smaller the overall angle of the blade body and the thinner the thickness, the better the cutting smoothness but the lower the overall strength. Therefore, the existing kitchenware products have various cutting edge sections, and the cutting edge sections are generally based on the requirements of combining strength, sharpness and smoothness as much as possible.

In the prior art, the cutting edge of the kitchen knife has a cross-sectional structure shown in fig. 1, which includes a-h type. The section of the edge-cutting edge of the kitchen knife is the most common section with the shapes of a cutting edge, the shapes of a type and a f type are similar in performance, the angle of the cutting edge at the tail end is large, the whole knife body is thick, the design of good strength is obtained by sacrificing certain sharpness and smoothness, and the shape of b is the design that the V shape of the knife body is kept at the tail end of the cutting edge and is not additionally processed, so that higher sharpness is obtained and the knife body is convenient to polish. The d type is a special grinding method, the highest sharpness can be obtained, but the retentivity is poor, the grinding difficulty is high, the c type is compromise treatment based on the d type, and the two shapes are not easy to maintain and are rare in the field of kitchen knives. The e-type kitchen knife is an ultrathin large flat edge, the cutting smoothness is the best, the sharpness is only inferior to the d-type kitchen knife, but the strength is not good, the design is rarely adopted for daily kitchen knives, a few kitchen knife products need to be polished and maintained continuously, any hard object cannot be cut, and the high durability cannot be realized even if high-strength materials are used. The g-type and the h-type are the inclined cutting edge design, and are mainly adopted in the Japanese kitchen knife for pursuing sharp and smooth cutting feeling, because only single-side edge cutting is performed, the cutting angle is only half of that of symmetrical edge cutting, the edge cutting is more in the field of razors or plane knives, and the main reason that the g-type and the h-type are not popularized in the field of kitchen knives is that the cutting feeling is inclined and does not conform to the habit of mainstream users.

The various conventional blade profiles are designed based on the performance of conventional mainstream steel, and in fact, the sharpness of the final cutter is also related to the grinding fineness of the tail end, and even if the tail end is at a large angle, if extremely fine final polishing grinding is adopted, superior cutting sharpness can still be obtained. With the development of powder metallurgy and other technologies, the properties of available metal materials for kitchen knives have greatly leap. The performance of high-end products such as high-end powder steel in the materials is far from that of the traditional steel, so that the design of the cutting edge is more possible on one hand, and on the other hand, a new problem is introduced, namely the existing grinding material technology cannot realize the delicate grinding which is easily realized on the traditional steel within a controllable cost range, so that the sharpness is reduced, and the problem to be solved is how to fully exert the performance of the high-performance materials.

SUMMERY OF THE UTILITY MODEL

In order to fully exert the performance of novel high performance material, obtain better sharpness and the smooth and easy sense of cutting, still compromise durability and intensity index simultaneously, the utility model provides a be suitable for high sharpness kitchen knife of high wear-resisting material.

The utility model provides a be suitable for high sharpness kitchen knife of high wear-resisting material, blade main part includes upper and lower two parts, and main part upper portion section is the rectangle, and main part lower part section is V type symmetry in the preceding direction of height of edging, and the contained angle theta of V type is 1.5 ~ 4 degrees, the terminal unilateral edging of main part lower part, with direction of height contained angle α be 13 ~ 30 degrees.

The edge-cutting height h of the tail end single-side edge along the height direction is 0.1 mm-1 mm.

The utility model has the advantages that:

the sharpness of the single-side edge can be obtained simultaneously, the tangent using sense of the traditional symmetrical edge is basically kept, the problems that most users are not used to the tangent using sense of the single-side edge and want to obtain better sharpness are solved, the performance advantages of the kitchen knife made of high-performance materials can be fully exerted, and the disadvantage that the high-performance materials are difficult to finely grind is avoided.

Detailed Description

The invention is further elucidated with reference to the drawings and the embodiments.

As shown in fig. 2, the high-sharpness kitchen knife suitable for high-wear-resistance materials comprises a knife body main body and a knife body main body, wherein the cross section of the upper portion of the main body is rectangular (not shown in fig. 2), the cross section of the lower portion of the main body is symmetrical in a V shape in the height direction of the cutting front edge, the included angle theta of the V shape is 1.5-4 degrees, the cutting edge of the tail end of the lower portion of the main body is single-sided, and the included angle α between the tail end of the lower portion of the main body and.

The cross-sectional structure of the cutting edge of the prior art knife is schematically shown in fig. 1. The utility model combines the advantages of the traditional cutting edge shapes of e, g and h, has very high sharpness similar to the h shape when being pressed in with slight force, can achieve the further higher sharpness and smooth cutting feeling of the e shape when being pressed in with force, and has almost the cutting point at the center, and the cutting feeling used by a user is almost not different from the kitchen knife with the symmetrical cutting edge shape; in addition, because the weakest position of e type sword is the terminal thinnest department, its terminal blade angle is very little, and is very thin again, therefore very easily damages, the utility model discloses after having increased terminal unilateral edge opening, its blade angle becomes the normal 13 ~ 30 degrees of h type, and the thickness of this section terminal has also obtained the increase, is showing intensity and durability that has promoted. The performance that novel material provided promotes in addition, just can still can satisfy daily user's user demand under excellent sharpness and the smooth and easy prerequisite of feeling of cutting, and has the durability, need not to apply special maintenance.

Examples

As shown in fig. 3, according to the utility model discloses one of them style kitchen knife that has trial-produced and accomplished, the cutting edge part has adopted american smelting pot sby crack ' S CPM S90V powdered stainless steel, this product scheme adopts traditional cutting edge design originally, because this powdered steel is extremely difficult to polish, even use the diamond, the grinding device that exceeds 100 mesh fineness just can't produce the effect of polishing almost, therefore can't realize the final meticulous blade of high degree of completion, its result is exactly that although the durability surpasses traditional product by a wide margin, the sharpness is obviously just as can be finely ground the kitchen knife like 1000 mesh ordinary steel on the contrary, change into afterwards and adopt the utility model discloses a scheme, knife body main part upper portion height is 20 mm (can adjust according to required kitchen knife focus and usage), knife body lower part height is 50 mm, the contained angle theta of V type is 2 degrees, terminal unilateral cutting edge angle α is 20 degrees, cutting edge height 0.4mm, under the condition of only having used 80 mesh grinding diamond equipment terminal cutting edge grinding, final sharpness and smooth feeling surpass the sharp contrast degree of cutting edge that still obviously to bring the traditional kitchen knife design, the contrast material has not proved simultaneously.
