Welded blade of rotary shaver

Abstract

The invention discloses a welded blade of a rotary shaver. The welded blade comprises a blade base and a cutter ring arranged on the blade base, wherein the cutter ring comprises a plurality of cutters which are rotationally distributed by taking a central shaft of the blade base as a central shaft, and the cutters are welded with the blade base. The problem that in the prior art, a high-hardness material cannot be used as a cutter material for shaving is solved, the manufactured cutters are good in cutting edge retentivity, high in abrasion resistance and long in service life, meanwhile, the cutters can be independently ground, the requirement for the performance of grinding equipment is low, and the requirement for operation of workers is low.

Description

technical field [0001] The invention relates to a welded blade of a rotary shaver, which belongs to the field of shaver. Background technique [0002] At present, the blades of rotary razors are basically obtained by sheet metal stamping and bending to obtain the blade body and then polished to obtain the blade edge. Limited by this manufacturing process, the blade has a very large selectivity in material selection. Limitations, generally use materials with low hardness such as ordinary stainless steel, and the blades made of such materials are not very wear-resistant, and often after two or three years, different degrees of tool edge wear will occur and cause The sharpness decreases or the edge breaks, resulting in gaps, which lead to quality problems such as shaving and poor shaving during the shaving process of the razor. For example, the application number is CN200780042342.8, and the patentee is Royal Philips Electronics Co., Ltd. Co., Ltd.’s Chinese patent, and for ex...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a welded blade of a rotary razor, which not only solves the problem in the prior art that high-hardness materials cannot be used as cutter materials for shaving, but also the obtained cutter has better edge retention Good, strong wear resistance, long mission life, and the tool can be ground separately, with low performance requirements for grinding equipment and low operation requirements for workers

[0005] This technical solution connects the cutter to the blade base by welding, which not only solves the problem that high-hardness materials cannot be used as the cutter material in the prior art for shaving, but also the obtained cutter has good cutting edge retention. Strong wear resistance, long mission life, and the tool can be ground separately, with low performance requirements for grinding equipment and low operation requirements for workers
