【発明の詳細な説明】 〔産業上の利用分野〕 本発明はドットマトリックス型プリンタヘッドに用い
られる印字ワイヤに関するものである。Description: BACKGROUND OF THE INVENTION The present invention relates to a printing wire used in a dot matrix type printer head.
これまで、ドットマトリックス型プリンタヘッドに用
いられる印字ワイヤとして、要求されている材質的特性
は下記の３点であると考えられていた。Heretofore, it has been considered that the following three material properties are required for a printing wire used in a dot matrix type printer head.
（１） ワイヤの耐摩耗性が高いこと。ワイヤ先端はイ
ンクリボンを108回以上も打点するため、先端が摩耗
し、印字が不明瞭となる。また、ワイヤはガイドと常に
摺動しているため、ワイヤ側面が摩耗して印字精度を悪
くする原因ともなっている。(1) The wire has high wear resistance. Since the wire tip to RBI more than 10 8 times an ink ribbon, tip wear, printing becomes unclear. In addition, since the wire is always slid with the guide, the wire side surface is worn, which causes a deterioration in printing accuracy.
（２） ワイヤが軽量であること。印字ワイヤは高速度
で運動しなければならず、印字速度を大きくするために
は、ワイヤが軽量であることが必要である。(2) The wire is lightweight. The printing wire must move at a high speed, and to increase the printing speed, the wire needs to be lightweight.
（３） ワイヤの靭性が高いこと。ワイヤは中間のガイ
ドによってわん曲されて配置しているため、ワイヤ組立
中や印字中に折損し易いので、靭性の高い材質であるこ
とが必要である。(3) High toughness of the wire. Since the wire is bent and arranged by an intermediate guide, the wire is easily broken during assembling the wire or during printing, and therefore, it is necessary to use a material having high toughness.
この種の印字ワイヤには一般に超硬合金細線、タング
ステン細線、高速度工具鋼細線等が用いられている。こ
のうち超硬合金は、耐摩耗性に優れているが、比重が大
きいためワイヤが重く、高速印字には適さない。また、
靭性も低いので使用中または組立中に折損する等、信頼
性の点で十分でない。For this type of printing wire, generally, a cemented carbide thin wire, a tungsten thin wire, a high-speed tool steel thin wire, or the like is used. Among them, cemented carbide is excellent in abrasion resistance, but has a large specific gravity, so that the wire is heavy and is not suitable for high-speed printing. Also,
Since the toughness is low, it is not sufficient in reliability, such as breakage during use or assembly.
タングステンは比重が大きい、強度の塑性加工のた
め、ファイバー組織が発達し、二枚割れを発生し易い、
耐摩耗性が十分でない等の欠点がある。Tungsten has a large specific gravity, and because of high-strength plastic working, the fiber structure develops and double cracks are easily generated.
There are disadvantages such as insufficient abrasion resistance.
高速度鋼は超硬合金やタングステンに比較すると比重

硬度が得られ、かつ適量の未固溶炭化物を分散している
ために耐摩耗性にも優れており、ドットプリンタ用印字
ワイヤとして多量に使用されている。高速度工具鋼には
通常の溶製法によるものと、粉末法により製造されたも
のとがあるが、粉末高速度鋼の方が耐摩耗性が高い。と
ころが、印字プリンタのより以上の高速化および高寿命
化のためには、従来の粉末高速度工具鋼では耐摩耗性が
まだ不十分である。High-speed steel has a specific gravity of about half that of cemented carbide and tungsten, and has high toughness. Moreover, it has a high hardness of HV700 to 900, and has excellent wear resistance because of dispersing an appropriate amount of undissolved carbides, and is used in large quantities as a printing wire for dot printers. There are two types of high-speed tool steel: those produced by the usual melting method and those produced by the powder method. The powdered high-speed steel has higher wear resistance. However, in order to further increase the speed and extend the life of the printing printer, the wear resistance of the conventional powdered high-speed tool steel is still insufficient.

A method of shock hardening the tip portion by laser irradiation or the like as disclosed in 54713, a method of coating a wire surface with a hard compound by a chemical vapor plating method disclosed in JP-A-52-96119, etc. are proposed. Have been.

い。Among the conventional methods for improving the wear resistance of printed wires, a method of joining a hard alloy tip to the tip of the wire, a method of shock quenching the tip by laser irradiation, etc., and a chemical vapor plating of the wire surface The method of coating with a hard compound by the method has a problem that the mass productivity is poor and the cost is high. At present, it has not been put to practical use on an industrial scale.

れたワイヤ材を提供する必要がある。In order to improve the life of the printing wire, the present inventor observed and investigated the state of wear of the wire tip, and found that the wire tip was parallel to the abrasive type abrasion caused by graphite fine particles, which are pigments or dyes contained in the ink. It was found that wear due to corrosion was progressing simultaneously. This is considered to be the corrosive action of the wire material by several percent to several tens percent of the special fatty acids constituting the ink. Therefore, in order to improve the printing life, it is necessary to provide a wire material having excellent corrosion resistance as well as abrasive wear resistance.

寿命化に対応できる印字ワイヤを提供することである。SUMMARY OF THE INVENTION An object of the present invention is to provide a printing wire capable of improving the wear resistance and corrosion resistance of a steel-based material having a low specific gravity and high toughness to cope with a high speed and a long life.

%, W 20.0% or less, Mo 15.0% or less, V 15.0% or less, Si 2.0% or less, Mn 1.0% or less, balance Fe and unavoidable impurities, excellent in corrosion resistance and wear resistance. In addition to the wire for dot printers or the above composition, further contains 16.0% or less of one or two of Ni 3.0% and Cu 3.0% or less, the balance being Fe and unavoidable impurities, and excellent corrosion and wear resistance A wire for a dot printer. More preferably,
This is a wire for a dot printer in which the wire material composed of the above chemical components is manufactured by a powder method.
以下に本発明の成分限定理由を述べる。 The reasons for limiting the components of the present invention are described below.
Ｃはマルテンサイトの格子ひずみを大きくして硬いマ
トリックスとし、ワイヤの耐アブレッシブ摩耗性を向上
せしめる効果がある。C has the effect of increasing the lattice strain of martensite to form a hard matrix and improving the abrasive wear resistance of the wire.
さらに、Cr、Ｗ、Mo、Ｖと反応して硬い炭化物を形成
し、耐アブレッシブ摩耗性をより一層向上させる。Ｃが

物形成元素との兼ね合いにより、0.95％以上、さらに望
ましくは同様に1.5％以上とする。3.0％を越えるとマト
リックスが異常に脆くなって、本発明の目的の一つであ
る鋼特有の靭性が失われるので、Ｃは0.6〜3.0％とし
た。Further, it reacts with Cr, W, Mo, and V to form a hard carbide and further improves abrasive wear resistance. C is
If it is less than 0.6%, the above effect is not sufficient. Desirably, it is 0.95% or more, more preferably 1.5% or more, in view of the balance with the carbide forming element. If it exceeds 3.0%, the matrix becomes abnormally brittle and the toughness specific to steel, which is one of the objects of the present invention, is lost. Therefore, C is set to 0.6 to 3.0%.
Crは本発明における重要な構成元素である。インクリ
ボン中に含有されている樹脂酸による腐食摩耗の進行を
抑制するためには、Cr含有の効果が大きく、Cr含有量の
高いほど腐食量は少ない。従来の高速度鋼製ワイヤと比
較して、Cr含有量が５％以上になると、その効果が明瞭
に現れる。Cr is an important constituent element in the present invention. In order to suppress the progress of corrosion and wear due to the resin acid contained in the ink ribbon, the effect of containing Cr is large, and the higher the Cr content, the smaller the amount of corrosion. When the Cr content is 5% or more as compared with the conventional high-speed steel wire, the effect is clearly exhibited.
本発明の特徴は、高速度鋼のもつCrが前記のＣと結合
して、硬い炭化物を形成し、ワイヤのアブレッシブ摩耗
の進行を押える効果による優れた耐摩耗性を活かしつ
つ、高Cr化による耐食性の向上をも兼備したワイヤ素材
を提供しようとするものであるが、本発明の合金組成で
Cr含有量が10％以上になると伸線性の著しい低下が認め
られ、工業的規模での製造が困難なことが明らかとなっ
た。したがって、Cr含有量は５〜10％とする。The feature of the present invention is that the Cr of the high-speed steel is combined with the C to form a hard carbide, and while utilizing the excellent wear resistance due to the effect of suppressing the progress of the abrasive wear of the wire, the Cr content is increased. The purpose of the present invention is to provide a wire material that also has an improved corrosion resistance.
When the Cr content was 10% or more, a remarkable decrease in drawability was recognized, and it became clear that production on an industrial scale was difficult. Therefore, the Cr content is set to 5 to 10%.
ＷおよびMoは、Crと同じくＣと結合して硬い炭化物を
形成するのでアブレッシブ摩耗に対し有効な元素である

下、Mo 15.0％以下含有させる。特に硬度の高いワイヤ
を必要とする場合には、Ｗ＋2Mo量で4.0％以上、望まし
くは10％以上含有した素材が適する。なお、要求特性、
特に靭性との兼ね合いによって、Ｗ 15％以下、Mo12％
以下、Ｗ＋2Mo 30％以下、さらにはＷ 13％以下、Mo
11％以下、Ｗ＋2Mo 24％以下とする。W and Mo, like Cr, combine with C to form hard carbides, and are effective elements for abrasive wear. At the same time, tempering causes secondary hardening, thus hardening the matrix and further abrasion resistance. The effect of improving the performance is great. In addition, since it also has the effect of reducing the decrease in hardness when heated to a high temperature, when brazing a wire to an amateur, it is possible to minimize the decrease in the hardness of the joint and reduce fatigue. This is effective for greatly improving the service life. In order to effectively exert the above effects, W is contained at 20.0% or less and Mo is contained at 15.0% or less. Particularly when a wire having a high hardness is required, a material containing 4.0% or more, preferably 10% or more in W + 2Mo amount is suitable. The required characteristics,
Especially, due to the balance with toughness, W 15% or less, Mo 12%
W + 2Mo 30% or less, W 13% or less, Mo
11% or less, W + 2Mo 24% or less.
ＶもまたＣと結合して硬い炭化物を形成する。 V also combines with C to form a hard carbide.
特に、Ｖ炭化物の硬さは約HV3000でCr炭化物（約HV15
00）の２倍の硬さを有しているので、アブレッシブ摩耗
に対し有効な作用を及ぼす。したがって、耐摩耗性の向
上には可能な限り多く含有させたいが、逆にＶ炭化物は
マトリックスとの濡れ性が悪く、靭性を劣化させる悪影
響も併せ持っているので、Ｖは15％以下とした。望まし
い添加範囲は1.0〜10％、さらに望ましくは3.0〜8.0％
である。In particular, the hardness of V carbide is about HV3000 and Cr carbide (about HV15
Since it has twice the hardness of (00), it has an effective effect on abrasive wear. Therefore, it is desirable to contain as much as possible to improve the wear resistance. On the contrary, V carbide has a bad wettability with the matrix and also has an adverse effect of deteriorating the toughness. Therefore, V is set to 15% or less. Desirable addition range is 1.0 to 10%, more preferably 3.0 to 8.0%
It is.
Siは脱酸剤として添加し、さらにマトリックスに固溶
して硬さを高める効果があるが、多すぎると靭性低下を
招くので２％以下含有させる。Si is added as a deoxidizing agent, and has the effect of further forming a solid solution in the matrix to increase the hardness. However, if it is too much, the toughness is reduced.
Mnも脱酸剤として添加するが、多すぎると焼入れ後の
硬さが低くなるので１％以下含有させる。Mn is also added as a deoxidizing agent, but if it is too much, the hardness after quenching becomes low.
以上述べた合金元素添加により、本発明の目的は十分
に達成されるが、さらにNi3％以下、Cu3％以下の１種ま
たは２種以上を合計で16％以下含有させることにより、
脂肪酸による腐食摩耗により一層の効果が現われる。特
に脂肪酸の割合が高いリボンに対し有効である。The object of the present invention is sufficiently achieved by the addition of the alloy elements described above. However, by adding one or more of Ni3% or less and Cu3% or less in a total of 16% or less,
Further effects are exhibited by the corrosive wear caused by fatty acids. It is particularly effective for ribbons having a high proportion of fatty acids.
本発明の合金は、Ｗ、Mo、Ｖなどの炭化物が多量に存

り、本発明の目的に最も適したプリンターワイヤ用素材
が得られる。The alloy of the present invention contains a large amount of carbides such as W, Mo, and V. Since these carbides tend to become coarse rods or squares in a normal production method, when used as a wire material, the size of the steel ingot is reduced, the cooling rate during solidification is increased, and the carbides are refined. It requires some ingenuity. In particular, the above alloy is manufactured by a powder method, and after consolidation, it is made into a wire to have a composition in which fine and spherical carbides are uniformly distributed, and a material for a printer wire most suitable for the purpose of the present invention is obtained.
