Conventionally, when manufacturing this type of outer cutter using the etching method, first, as shown in Figure 7, a 45 to 90μ
Corrosion-resistant films 3, 3 having a large number of openings 2 corresponding to the hair introduction holes of the outer cutter are formed on the front and back surfaces of a thick outer cutter material 1. Thereafter, this outer cutter material 1 is immersed in an etching solution, and the portions of the outer cutter material 1 corresponding to the openings 2 are corroded to form a large number of hair introduction holes 4, as shown in the figure. After the etching process, the corrosion-resistant films 3, 3 are peeled off from the front and back surfaces of the outer blade material 1.

When this outer cutter is used, its front surface becomes the skin contact surface, and the back surface becomes the sliding contact surface with the inner cutter. At this time, the outer cutter material 1 becomes the skin contact surface.
Hair introduction holes 4 are formed by etching on the surface side of the
If the edge 5 remains on the hole edge,

This invention focuses on this fact, and when etching the outer cutter material, the surface of the outer cutter material is coated with ultraviolet rays or electron beams, which can withstand the etching solution and become a corrosion-resistant film, and also serve as a reinforcing material for the outer cutter ribs. Manufacture of outer blades for electric shavers that can omit buffing by coating and forming a pattern with a curable resin, and can also reduce the thickness of the outer blade material and shorten etching time. The main feature of this method is that a pattern made of ultraviolet or electron beam curable resin is integrated on the surface of the outer blade material, which has a large number of bristle inlets and auxiliary ribs between the bristle inlets. A corrosion-resistant film is formed on the back surface of the outer blade material, and then a portion of the outer blade material corresponding to the hair inlet is etched with an etching solution to remove the bristles that communicate with the hair inlet. The point is to create an introduction hole to obtain an outer cutter having the pattern on the surface of the outer cutter material.

Next, this outer cutter material 9 is immersed in an etching solution such as ferric chloride. As shown in FIG. 5, this immersion corrodes the portion of the surface of the outer cutter material 9 that corresponds to the hair introduction ports 11 of the pattern 10, and the hair introduction holes 7 communicating with the hair introduction ports 11 of the pattern 10 are removed from the outer cutter material 9. Create to. Finally, the corrosion-resistant film 13 is removed using a solvent. Removal of the corrosion-resistant film 13 with this solvent is optional, and the corrosion-resistant film 13 can be scraped off with the cutting edge by rotating the inner cutter several times after the electric shaver is assembled.

In this way, in this invention, when etching the outer cutter, the pattern 10 made of ultraviolet or electron beam curable resin is applied as a corrosion-resistant film on the surface side of the outer cutter material 9, and the pattern 10 is applied to the outer cutter material 9 after etching. Since it is used as a reinforcing material for the rib 8 as it is, not only the work of removing the corrosion-resistant film on the surface side of the outer cutter material 9 after etching is omitted, but also
The thickness t1 of the outer cutter material 9 can be made extremely thin to about 10 to 20μ. Therefore, a major feature is that the etching time can be significantly shortened. In addition, by thinning the outer cutter material 9, in other words, by reducing the material of the outer cutter material 9, which is the object to be etched, it is possible to control the concentration of the etching solution.
Pollution control treatments will become easier.

Furthermore, by using ultraviolet or electron beam curable resin as the material for the pattern 10, not only can the above-mentioned corrosion resistance and reinforcing function of the ribs 8 be sufficiently achieved, but also the curing time for the surface of the outer blade material 9 is shortened. Furthermore, since the curing process involves hardly any heat being applied, there is no possibility of thermal effects such as crystal enlargement on the outer blade material 9.

さらに、エツチングにより外刃素材9の表面側

Furthermore, the edges 14 (see Fig. 6) formed on the surface side of the outer cutter material 9 by etching are pattern 1.
0 and the skin is applied to the surface of this pattern 10, so there is no need to buff the edges 14 after etching, which has the advantage of reducing processing costs.
