する。(Means for Solving the Problem) A wear-resistant member made of a metal compound-based inorganic material, which is an integral part of a pair of wear-resistant pieces, is attached in advance to the tip of the elastic member, and then the wear-resistant member is divided under pressure. Namely, the present invention is a method for manufacturing a pen nib by attaching a pair of wear-resistant pieces to the tip of an elastic member to serve as a writing abutment part, the method comprising: preparing a metallized 6-component system consisting of a pair of wear-resistant pieces in advance; The gist of the present invention is a method for manufacturing a pen nib, which is performed by attaching an inorganic wear-resistant member to the tip of an elastic member and then dividing it under pressure.
以下、添付図面を基にして説明する。The following description will be made based on the accompanying drawings.
第１図において、参照符号１は金属１合金。In FIG. 1, reference numeral 1 indicates metal 1 alloy.

着、溶着、圧入など適宜方法によって固着している。This figure shows an elastic member made of synthetic resin, etc.
In order to increase elasticity, it has a flat plate shape as a whole and has a cutout 2 in the front. Reference numeral 3 indicates a wear-resistant member made of natural or synthetic gemstones such as ruby and sapphire, or metal compound-based inorganic materials such as ceramics such as alumina and zirconia. It is fixed by an appropriate method.

塑性変形を伴うものであってもよく、第２図にその一例

ように上に凸に塑性変形させたものであり、耐摩耗性部
材３はスリット２の延長部を形成するよう分割されて耐
摩耗片３ａ、３ｂとなっている。This is pressurized and divided so that the wear-resistant member becomes a pair of wear-resistant pieces serving as writing contact portions. This pressurization may be accompanied by plastic deformation of the elastic member 1, an example of which is shown in FIG. That is, in FIG. 2, the slit 2 is plastically deformed in an upwardly convex manner with the direction of the ridge line, and the wear-resistant member 3 is divided to form an extension of the slit 2 to form a wear-resistant piece. 3a and 3b.
これを必要に応じて研摩など施し、書き味等所望の特性
を有するペン先とする。This is polished as necessary to obtain a pen nib with desired characteristics such as writing quality.
以上において、スリット２の存在は耐摩耗性部材３０分
割位置を定める上でも役立っているが１例えば第３図に
示すように耐摩耗性部材３に分割位置規制をなすための
薄肉部４を適宜形成しておくようにすることもできる。In the above, the presence of the slit 2 is also useful in determining the dividing position of the wear-resistant member 30. For example, as shown in FIG. It is also possible to keep the shape formed.
また、耐摩耗性部材３が単結晶よシなるときは、結晶面
の選択も分割方向を定める上で都合がよい。Further, when the wear-resistant member 3 is made of a single crystal, selection of the crystal plane is also convenient in determining the dividing direction.
尚、形状等適宜であり１例えば耐摩耗性部材３を分割す
る前と後との形状がいずれも第２図のようなものとする
こともできる。耐摩耗性部材３の形状を予め断面山形の
ものとしておく訳である。Note that the shape and the like may be determined as appropriate; for example, the shapes before and after the wear-resistant member 3 are divided may both be as shown in FIG. 2. This is because the shape of the wear-resistant member 3 is set in advance to have a chevron-shaped cross section.
（作用）
耐摩耗性部材３の材質である金属化合物系無機物は金属
や合金などと違って、耐摩耗性とともに脆性にも富む。(Function) Unlike metals, alloys, etc., the metal compound-based inorganic material that is the material of the wear-resistant member 3 is rich in wear resistance and brittleness.
この脆性を利用して加圧分割し、その後、耐摩耗性の活
用をなして、ペン先の寿命を長く保つ。Taking advantage of this brittleness, the pen is divided under pressure, and then its abrasion resistance is utilized to extend the life of the nib.
（実施例） 厚さ１ｆｌの１４に金合金の板体を打ち抜き。(Example) Punch out a gold alloy plate into a size 14 with a thickness of 1 fl.

。全長は２５８２弾力性部材長は２０ｍ、スリット長は
７ｍｍ、後端から１０ｍ分は６Ｍの一定幅である。After making the tip a thin part, a slit is formed with a diamond cutter to make it an elastic member, and a wear-resistant member made of alumina ceramic having the shape shown in Fig. 3 is adhered to the tip, and the whole is made into a part as shown in Fig. 1. A product with the shape shown in was obtained. The total length is 2582, the elastic member length is 20 m, the slit length is 7 mm, and the 10 m from the rear end has a constant width of 6 m.
これを直径１０器のステンレス棒上にスリットの方向が
棒の長手方向と一致するように載置し。This was placed on a stainless steel rod with a diameter of 10 mm so that the direction of the slit coincided with the longitudinal direction of the rod.

た。A rubberized plate is applied from above and pressure is applied to divide the wear-resistant member.Furthermore, a stainless steel jig with a concave portion with the same curvature as the stainless steel rod is pressed from above to prevent it from coming into contact with the wear-resistant member. The elastic member was plastically deformed, a thin plate-shaped file was inserted into the divided portion of the wear-resistant member and polished, and the whole was barrel-polished to obtain a shape as shown in FIG.
