Personal care trimmer with high-reliability cutting edges and manufacturing method for personal care trimmer

Abstract

The invention relates to the field of personal care articles, and discloses a personal care trimmer with high-reliability cutting edges. The personal care trimmer with the high-reliability cutting edges comprises a cutting tool and a cutting head arranged at the end portion of the cutting tool; the cutting head is evenly provided with comb-shaped cutting teeth in the length direction. Each cutting tooth comprises a top face, a bottom face, an end face, an oblique face and two side faces, wherein the side faces and the top face intersect to form one first cutting edge; the side faces and the bottom face intersect to form one second cutting edge; the oblique face extends from the top face to the end face; the oblique face and the side faces form one third cutting edge. A connection face is arranged between every two adjacent cutting teeth, each connection face and the upper surface of the cutting head form one fourth cutting edge, and each connection face and the lower surface of the cutting head form one fifth cutting edge. The invention further discloses a manufacturing method for the personal care trimmer with the high-reliability cutting edges. The cutting head is formed in a punch forming mode, the sharp cutting edges are formed in the intersecting position of the arc faces and the bottom faces of the cutting teeth by polishing semi-finished parts, and the trimming efficiency and production efficiency of products are greatly improved.

Description

technical field [0001] The invention relates to the field of personal care products, in particular to a personal care trimmer with highly reliable cutting edges and a manufacturing method thereof. Background technique [0002] Most of the cutters of traditional personal care trimmers are machined by milling or grinding, and there are two problems as follows: [0003] (1) The cutting angle is very large, not sharp, and the shearing effect is poor; [0004] (2) The mechanical processing method of milling or grinding consumes a lot of labor cost and time cost, and the output is low and the cost is high. [0005] In response to the above problems, there are improved designs on the market, which use metal stamping to prepare products, and forcefully extrude the cutting edge, shearing edge or tooth shape, but there are still some problems, such as: [0006] (1) Cracks are prone to appear on the cutting edge, shearing edge or tooth shape after being strongly extruded, which will ...

AI Technical Summary

Problems solved by technology

[0006] (1) Cracks are prone to appear on the cutting edge, shearing edge or tooth shape after being strongly extruded, which will lead to defects such as uneven blades, missing corners, flanging, and draping, thereby reducing the shearing efficiency;

[0007] (2) There is a horizontal cutting edge between the knife teeth, because it is parallel to the shearing direction of the knife, the shearing operation cannot be performed, and the shearing efficiency is also reduced
