Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は縫製や、編成に使用するミシン針。[Detailed description of the invention] [Industrial application field] The present invention is a sewing machine needle used for sewing and knitting.
メリヤス針、フェルト針等の繊維機械用針に間するもの
である。It is used between textile machine needles such as knitting needles and felting needles.
従来のミシン針、メリヤス針、フェルト針等は、重量％
でＣ：Ｑ、６〜１．１０の高炭素鋼線材が一般に使用さ
れ、所要の針形状に成形後、焼入れ焼戻しされて、強度
と靭性と耐摩耗性が付与されていた。Conventional sewing machine needles, stockinette needles, felting needles, etc. are weight%
A high carbon steel wire rod with a C:Q of 6 to 1.10 is generally used, and after being formed into the desired needle shape, it is quenched and tempered to impart strength, toughness, and wear resistance.
上記従来の針は、所望の強度と靭性と耐摩耗性を付与す
るために、もっばら高炭素鋼線材の炭素含有率を加減し
たり、焼入れ焼戻し温度を変えたりされていたが、ある
硬さ以上になると靭性が低下し、折れ易くなり、一定の
硬さ以上にできないばかりか、耐摩耗性においてもも問
題があった。In order to give the above-mentioned conventional needles the desired strength, toughness, and wear resistance, the carbon content of the high carbon steel wire rod was adjusted or the quenching and tempering temperature was changed. If the hardness is higher than that, the toughness decreases and it becomes easy to break, and not only can the hardness not exceed a certain level, but there are also problems in wear resistance.
そのため、縫製、編成に使用すると、短期間で針の交換
をしなければならなかった。Therefore, when used for sewing or knitting, the needle had to be replaced within a short period of time.
本発明は、従来技術の有する上記問題に鑑みてなしたも
のであり、強度、靭性、耐摩耗性に富んだ針を提供する
ことを目的とする。The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a needle with high strength, toughness, and wear resistance.

次に、本発明の繊維機械用針の謂の化学組成を限定した
理由について説明する。Next, the reason for limiting the so-called chemical composition of the textile machine needle of the present invention will be explained.
Ｃは、焼入れ焼戻しにより針として必要な硬さと強度を
確保するために０．５０％以上必要であるが、過剰にな
ると靭性が低下するので０．７％以下が好ましい。C is required to be 0.50% or more in order to ensure the hardness and strength necessary for the needle through quenching and tempering, but if it is excessive, the toughness will decrease, so it is preferably 0.7% or less.
Ｓｉ は、焼入れ性の向上と焼入れ硬度を高（する働き
があり、また、鋼の脱酸剤としても必要な元素で、１．
２％以上必要であり、１．６％を超えると靭性が低下し
、針として必要な靭性を確保できなくなるので、その範
囲は１．２〜１．６％とする。Si has the function of improving hardenability and increasing quench hardness, and is also a necessary element as a deoxidizing agent for steel.
2% or more is required, and if it exceeds 1.6%, the toughness decreases and it becomes impossible to ensure the toughness necessary for the needle, so the range is 1.2 to 1.6%.
Ｍｎは、Ｓｉ と同様に脱酸脱硫剤としても必要であり
、鋼を粘くして靭性を向上させる元素である。通常、脱
酸脱硫剤としては０．４０％以上であり、０．９０９１
！ｉを超えると線材加工性（冷間加工性）を低下させる
ので、その範囲は０．４０〜０．９０％とする。Like Si, Mn is also necessary as a deoxidizing and desulfurizing agent, and is an element that makes steel sticky and improves its toughness. Usually, as a deoxidizing desulfurizing agent, it is 0.40% or more, and 0.9091
! If it exceeds i, wire workability (cold workability) is reduced, so the range is set to 0.40 to 0.90%.
Ｃｒは、焼入れ性を向上させ、焼戻し軟化抵抗を上げ、
また、Ｃと結合してＣｒ炭化物を形成し、耐摩耗性も向
上させる。よって、０．４０％以上必要であるが、１．
５０％を超えるとＣｒ炭化物が増大して靭性を低下させ
るので、その範囲は０．４０％〜１．５０％とする。Cr improves hardenability, increases temper softening resistance,
Further, it combines with C to form Cr carbide, which also improves wear resistance. Therefore, 0.40% or more is required, but 1.
If it exceeds 50%, Cr carbide increases and the toughness decreases, so the range is set to 0.40% to 1.50%.
■は、焼戻し軟化抵抗を上げ、また、鋼の組織を微細化
するので、高強度において靭性を向上させる。よって、
Ｑ、０５％以上必要であるが、０．２５％を超えるとＶ
炭化物を形成し、靭性が低下するので、その範囲は０．
０５〜（Ｌ２５％とする。(2) increases the temper softening resistance and refines the structure of the steel, so it improves the toughness at high strength. Therefore,
Q: 0.5% or more is required, but if it exceeds 0.25%, V
Since carbides are formed and the toughness is reduced, the range is 0.
05~(L25%.
