したものである。 Since the inner cutter blade 52 is rarely cleaned each time it is used, it has the disadvantage that it may corrode or rust due to adhesion of metal ions and bacteria.
The present invention aims to provide a method for manufacturing an inner cutter blade that can eliminate these drawbacks. The method of the present invention will be explained below with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional side view of a base piece 1 that is a material piece for the inner cutter blade, and is a sectional view of the base piece corresponding to the - line sectional view of the conventional inner cutter blade shown in FIG. 4 to 4 are longitudinal sectional side views illustrating the process of processing the base piece 1 to form an inner cutter blade. The method of the present invention includes a first step of making a base piece 1 having a predetermined inner cutter blade shape using aluminum as a material, and anodizing the base piece 1. The second step is to make the entire porous alumite blade piece 2 as shown in Fig. 2, and the third step is applied to the alumite blade piece 2 obtained in this step.
As shown in the figure, in the example of the photocurable resin liquid, there is a third step of forming a coating 3 with an ultraviolet curable resin liquid, and after this step, the coating of the photocurable resin liquid is cured by light irradiation. As shown in FIG. 4, the invention is characterized by having a fourth step of forming a reinforcing outer layer 4 on the surface of the alumite blade piece 2, and the corrosion resistance is increased by the alumite blade piece 2, and the reinforcement is The outer layer 4 reinforces the physical strength of the alumite blade piece 2, and furthermore, the micropores formed in the alumite blade piece 2 prevent the reinforcing outer layer 4 from peeling off.

１２とが１体成形される。 For example, the base piece 1 made in the first step can be manufactured by simultaneously punching out a large number of pieces from one aluminum plate using a punching method. In this case, the base piece 1 has a holder 5 when used. The base portion 11 held by the holder 5 and the blade portion 12 protruding and exposed from the holder 5 are integrally molded.

る利点がある。 The anodic oxidation treatment in the second step may be performed by known means, and in this case, the base piece 1
If the wall thickness is reduced to about 0.1 mm, the micropores 21 produced by the anodizing treatment will be formed penetrating the alumite blade piece 2, so that the coating 3 of the photocurable resin liquid As shown in the figure, there is an advantage that the alumite blade piece 2 is connected inside the alumite blade piece 2, so that the reinforcing outer layer 4 obtained by hardening the alumite blade piece 2 is firmly attached to the alumite blade piece 2.
上記第３工程における被膜３は、光硬化性樹脂

に塗着して形成しても良い。 The coating 3 in the third step may be formed by immersing the alumite blade 2 in a photocurable resin liquid, or alternatively, the coating 3 may be formed by dipping the alumite blade 2 in a photocurable resin liquid.
It may also be formed by applying it to.

中に浸漬する事が出来る。 In either case, the coating 3 is usually formed to cover the entire alumite blade piece 2, but in some cases, the coating 3 may cover the base 1 of the base piece 1.
It is not necessary to form the coating 3 on the base 22 of the alumite blade piece 2 corresponding to No. The alumite blade piece 2 can be immersed into the resin liquid from the blade part 23 by gripping the base part 22 with a jig.
即ち、上記補強外層４は、少くともアルマイト

順次照射してもよい。 That is, the reinforcing outer layer 4 may be formed at least on the blade portion 23 of the alumite blade piece 2, and in this case, the base portion 22 is inserted and held in the holder 5,
The holder 5 protects it from external impact. In the fourth step, the hard reinforcing outer layer 4 is formed by irradiating the coating 3 with, for example, ultraviolet rays. Alternatively, a large number of alumite blade pieces 2 that move continuously and sequentially may be sequentially irradiated at one location.

部のアルマイト刃片２の刃先が露出する。 The blade end layered portion 41 of the reinforcing outer layer 4 obtained in this step may be cut off before being assembled into an electric shaver, but in reality, the inner cutter blade is in slight contact with the outer cutter blade. Even if such cutting is not performed, the blade end multilayer portion 41 is worn and ground by the outer cutter blade at the beginning of use, and the cutting edge of the internal alumite blade piece 2 is exposed.
本発明方法はこの様に、アルマイト刃片２に光
硬化性樹脂の補強外層４を形成したものであるか
