Comb-tooth blade structure and processing method

Abstract

The invention discloses a comb-toothed blade structure, which is composed of a blade base body and a blade tooth part. The part of the blade base body close to the blade teeth is bent toward the blade face to form the blade teeth part. The two sides of the blade teeth part also form concave and convex grooves. The inner part of the material is shaved off to form the knife face, and at the same time, part of the material is shaved off from the concave and convex grooves to form comb-shaped teeth and sharp-edged blades at one time. The invention also discloses a processing method of the comb-shaped blade. The present invention processes and shapes cutter teeth and sharp-edged blades at one time, significantly fewer procedures, lower requirements on molds and stamping equipment, prolongs service life of molds, significantly lower production costs, and greatly improves production efficiency. Moreover, the acute angle of the blade of the present invention can be determined by adjusting the shape of the concave-convex grooves on both sides. The present invention can form a blade with a smaller acute angle from the concave-convex grooves, thereby improving the cutting efficiency.

Description

technical field [0001] The invention relates to the tooth and blade structure of the comb-toothed blade, and the processing method of the comb-toothed blade, which is suitable for electric hair clippers, sideburns or side blades of electric shavers, women's shaver and animal shaver Fixed knives and moving knives for other products. Background technique [0002] Conventionally, the following methods are known for processing comb-shaped inserts. [0003] One is to press the blank of the blade to form the cutter teeth, and then perform grinding on the area where the blade will form the cutter face to form a 90-degree cutter edge. The cutting efficiency of the blade produced by this processing method is relatively low. [0004] Another method is to cut the blank material of the blade with a grinding wheel or a milling cutter. This processing method can make the blade of the knife tooth form an acute angle less than 90 degrees, but it cannot form a relatively small acute angle. ...

AI Technical Summary

Problems solved by technology

[0003] One is to stamp the blade blank to form the blade, and then grind the blade to form a 90-degree blade in the area where the blade is to be formed. The cutting efficiency of the blade produced by this processing method is relatively low

[0004] Another method is to cut the blank material of the blade with a grinding wheel or a milling cutter. This processing method can make the blade of the knife tooth form an acute angle less than 90 degrees, but it cannot form a relatively small acute angle. This processing method produces The cutting efficiency of the blade is still not high enough

[0005] Another method is the patent No.: ZL03122105.X narrated a haircut cutting edge processing method, by punching the comb-shaped fixed knife or the blade of the moving knife, utilizing the cutting process or etching process of the grinding wheel After one-time processing and roughly forming a comb-like knife tooth, the blade of the knife tooth is formed into a smaller acute angle by step-by-step forging multiple times. The cutting efficiency of the blade produced by this processing method is relatively high, but this This processing method has many procedures, high requirements for molds and stamping equipment, and the service life of the mold is short. In short, this processing method has high cost and production efficiency is not high enough.
