Hair clipper cutter and manufacturing method thereof

Abstract

A cutter of a hair clipper and a method of manufacturing the same are provided. A half processing blade having multiple circular penetrating holes is punched by punching equipment. Grinding wheel equipment is utilized to cut and machine the front end of each circular penetrating hole of the half processing blade toward the direction of the circular penetrating hole so that two corresponding blade portions are formed. In this way, multiple tooth units are manufactured on the movable blade. The cutter is characterized in that two side surfaces of the front end of any tooth unit are provided with the blade portions, and an arc groove hole is formed between the bottom end on any side of any tooth unit and the bottom end of one adjacent tooth unit.

Description

technical field [0001] The present invention relates to a cutting tool for a hair clipper and its manufacturing method, in particular to a process of processing a relatively thick metal plate into a cutting tool, and the structure of the cutting tool can improve the cutting efficiency and make the trimmed hair relatively flat. Background technique [0002] The blade of the hair clipper usually consists of a stationary fixed blade and a movable blade superimposed on the fixed blade, and the movable blade can move back and forth to cut the hair alternately with the fixed blade. [0003] In order to achieve a good cutting effect of the hair clipper blade and maintain a durable and stable performance, the current common technique is to choose a thicker metal plate material, and then use a grinding wheel to cut out the tooth profile, so that the tooth profile has an acute angle and maintains the same thickness. For structural strength, please refer to Figure 1A As shown in , it...

Problems solved by technology

[0005] 2. In addition, if Figure 3B As shown, because the bottom of the V-shaped alveolar 12 can be narrowed, so the hair 5 that enters the bottom of the V-shaped alveolar 12 as mentioned above can be squeezed, so the hair bundles can be tightly concentrated, and when cutting , the tightly concentrated hair strands will make the cutting more laborious, so there will be situations that reduce the cutting efficiency;

[0006] 3. Due to the large friction area at the bottom, the blade is more likely to heat up and become hot during use;

[0007] 4. Larger friction area results in higher power consumption;

[0008] 5. The above-mentioned processing method will increase the processing amount of the grinding wheel, reduce the life of the grinding wheel, and lead to the problem of increasing the processing cost.
