Blade structure formed in one time and machining method

Abstract

The invention discloses a blade structure formed in one time. The blade structure formed in one time consists of a blade base body and blade teeth, wherein the front portion of the blade base body directly forms a triangular cone, one conical face of the triangular cone is connected with the front portion of the blade base body, the bottom face of the triangular cone and the other two conical faces form the blade teeth, and corner cuts on two sides of the blade teeth are formed between the two conical faces and the bottom face. A machining method comprises the steps of adopting a ceramic material, a powder metallurgy material or a precise casting material and the like to form the blade structure by means of a die. On the premise that the strength of the blade teeth is ensured, the corner cuts on the two sides of the blade teeth are decreased as far as possible, the sharpness of the blade teeth is improved, and the cutting efficiency is higher. In addition, the thickness of the blade base body of the blade structure is not changed, the strength of the whole blade is not influenced, and the service life of the blade is long.

Description

technical field [0001] The invention relates to a cutter tooth and blade structure of a blade, in particular to a one-time forming blade structure and processing method, and is suitable for electric hair clippers, temple blades or side blades of electric razors, women's razors and Fixed and moving knives for animal shaver and other products. Background technique [0002] In the prior art, ceramic blades are usually molded with the help of ceramic materials, and their structure is as follows: figure 1 , Picture 1-1 , Figure 1-2 with Figure 1-3 As shown, it is composed of a blade base body 10 and a blade tooth 20 , the blade base body 10 near the blade teeth 20 forms an oblique triangular prism 30 , and the bottom surface and two side surfaces of the oblique triangular prism 30 directly form the blade teeth 20 . Such cutter teeth 20 form a cutting angle β on both sides between the two side surfaces and the bottom surface. The cutting angle β is generally between 60-80 d...

AI Technical Summary

Problems solved by technology

Such a knife tooth 20 forms a cutting angle β on both sides between the two side surfaces and the bottom surface. The cutting angle β is generally between 60-80 degrees, and the cutting effect is not ideal.

[0003] If the cutting angle β on both sides of the blade 20 is specially reduced in order to improve the cutting effect, the oblique triangular prism 30 will also be more inclined, causing the blade base 10 to be too thin near the blade 20, which will affect the strength of the entire blade and cause the blade Easy to break, short service life
