Problems solved by technology

[0003] In the prior art, there are generally two structures of cutters, one structure such as figure 1 As shown, the height direction is along the top of the tool to the edge of the knife, most of the upper part is vertical, and the lower end is oblique to form the edge of the knife. The thickness of the blade of this structure is relatively thick. user needs; another construct such as figure 2 As shown, its height direction is along the top of the tool to the edge of the knife, and the oblique line is formed from the upper part to the lower end to form the edge of the knife. The blade of this structure is thinner and sharper, but its strength is very low. When in use, it will form a curling edge, causing chipping

Embodiment 1

[0027] refer to Figure 3-5 , a sharp and strong knife, including a blade body 1 and a blade edge 2, the two outer surfaces of the blade body 1 along its height direction are symmetrically arc-shaped from the top of the blade DD'3 to the top of the blade FF'4 , the arc surface formula is: Among them, R is the radius of the arc surface, α is the thickness of EE' at the thickest point of the blade, β is the thickness of DD' at the top of the blade, and γ is the difference between EE' at the thickest point of the blade and DD' at the top of the blade Thickness difference, L is the height from the thickest part EE' of the blade to the edge G at the bottom of the blade.

[0028] The two outer sides DEF and D'E'F' of the blade body are symmetrically in the shape of an arc surface, and the blade FGF' is in a triangular shape; the height from the top of the blade body D-D'3 to the thickest part E-E'5 of the blade body is 10mm, the height from the thickest point E-E'5 of the blade t...

Embodiment 2

[0032] A kind of manufacturing method of the cutter described in embodiment 1 and intensity is good, comprises the following steps:

[0033] (1) Determine the radius and shape of the arc surface according to the arc surface formula;

[0034]

[0035] In the above formula, α=2mm, β=0.3mm, γ=0.1mm, L=70mm;

[0036] but

[0037] i.e. R 2 -[R-0.8] 2 =70 2

[0038] R=3062.9mm;

[0039] (2) Processing and forming by grinding device:

[0040] refer to Image 6 , install the workpiece 7 on the workpiece fixing plate 8, and fix it on the workpiece fixing plate 8 with a pressing device 9, the workpiece fixing plate 8 adjusts the grinding position of the workpiece under the action of the driving mechanism, and the workpiece fixing plate 8 is Set at a certain angle, insert the workpiece obliquely into the grinding wheel 10 for grinding. With the rotation of the grinding wheel, the cutting edge of the knife can be arc-shaped after grinding. In addition, by adjusting the angle...

Abstract

The invention relates to a sharp cutter with high strength and a manufacturing method thereof. The cutter comprises a cutter body and a cutter blade; the cutter body is in a circular arc camber shapein the height direction of the cutter body from the top of the cutter body to the top of the cutter blade, and the formula of the circular arc camber is shown in the description, wherein R is the radius of the circular arc camber, alpha is the thickness of the thickest portion of the cutter body, beta is the thickness of the top of the cutter blade, gamma is the difference of the thickness of thethickest portion of the cutter body and the thickness of the top of the cutter body, and L is the height from the thickest portion of the cutter body to a cutter blade opening of the bottom of the cutter blade; the ratio of the height from the top of the cutter body to the thickest portion of the cutter body to the height from the thickest portion of the cutter body to the cutter blade opening ofthe bottom of the cutter blade is 1:(4-30). The cutter is simple in structure and reasonable in design, and through the circular arc camber shape of the cutter body and formula setting of the circulararc camber, the formed cutter blade part is moderate in thickness and has high strength; meanwhile, the cutter also has high sharpness, the strength and the sharpness are well balanced, and the requirement of a user can be better met.

Description

technical field [0001] The invention relates to a kitchen utensil, in particular to a sharp and strong knife and a manufacturing method thereof. Background technique [0002] Knives, such as kitchen knives, are one of the kitchen utensils, mainly used for cutting meat and vegetables. Strength and sharpness are important parameters to consider the pros and cons of a knife. The strength and sharpness of the knife are mainly related to the thickness of the cutting edge. Generally speaking, the thicker the cutting edge, the stronger the corresponding strength; but the sharpness of the knife is opposite to the thickness of the cutting edge. , that is, the thinner the thickness of the cutting edge, the better the corresponding sharpness. [0003] In the prior art, there are generally two structures of cutters, one structure such as figure 1 As shown, the height direction is along the top of the tool to the edge of the knife, most of the upper part is vertical, and the lower end...
