Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、改良された極細線の伸線方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to an improved method for drawing ultra-fine wire.
従来、丹心線径が１００μｍ以下の線材から伸線を行な
う所謂極細線の線引の場合、極細線伸線機での抗張力が
小さいため、線材に接触抵抗の少ないディスクを被せ、
その上に細いナイロンテグスのようなヒゲフライヤーに
よって被処理線材にバックテンションを加えるようにし
ている。しかし、ゲフライヤーのテグス径が太く短い場
合は、バックテンションが強く第１パスのダイスのとこ
ろで断線を多く発生させ易い。また、デスク径が細く長
い場合は、逆に線振れからダイス前のところでガイド外
れを起こし、これまた第１バスのダイスで断線を多く発
生させ易い問題があった。Conventionally, in the case of so-called ultra-fine wire drawing, in which wires with a diameter of 100 μm or less are drawn, the tensile strength of the ultra-fine wire drawing machine is small, so the wire is covered with a disc with low contact resistance.
On top of that, back tension is applied to the wire to be processed using a hair flyer such as a thin nylon thread. However, when the diameter of the wire of the Geflyer is thick and short, the back tension is strong and many wire breaks tend to occur at the die in the first pass. Moreover, when the diameter of the desk is narrow and long, there is a problem in that the guide comes off in front of the die due to wire runout, which also tends to cause many wire breaks in the die of the first bus.
本発明は、かかる点に鑑みてなされたものであり、所定
の伸線処理が行なえると共に線材に付着した銅粉・塵等
も除去でき断線の少ない高品質の極細線材を容易に得る
ことができる伸線方法を提供するものである。The present invention has been made in view of these points, and it is possible to perform a predetermined wire drawing process, remove copper powder, dust, etc. attached to the wire, and easily obtain a high-quality ultra-fine wire with less disconnection. This provides a wire drawing method that can be used.
本発明は、線材の繰り出し装置から被処理線材を繰り出

走行する線材に該線材の走行方向と逆の方向からの送風
によって被処理線材にバックテンションを付加せしめて
いる伸線方法である。The present invention provides a method for feeding a wire rod to be processed from a wire rod feeding device and guiding it to a wire drawing device equipped with a wire drawing die to draw the wire to a desired outer diameter. This is a wire drawing method in which back tension is applied to the wire to be processed by blowing air from a direction opposite to the running direction of the wire.
本発明にかかる伸線方法によれば、伸線装置に導かれる
被処理線材に該線材の走行方向と逆の方向から送風を行

線の少ない高品質の線材を容易に得ることができる。According to the wire drawing method according to the present invention, air is blown from a direction opposite to the running direction of the wire rod to be guided into the wire drawing device to apply back tension to the wire rod.
Even if the wire diameter of the wire changes, it is easy to adjust and always apply a constant back tension to the wire, and at the same time copper powder, dust, etc. attached to the wire to be processed can be removed, resulting in high quality with less wire breakage. wire can be easily obtained.

The wire rods are sequentially supplied to the wire supply pipe 5 through the wire rods. The wire rod 2 to be processed that has exited the wire rod supply pipe 5 is transferred to a wire drawing device 10.
The wire revolves around drive capstans 8a and 6b, and is guided to a wire drawing die 7 provided between drive capstans 8a and 6b. This wire drawing die 7 can, for example, adjust the diameter of the wire material 2 to be processed from 0.05 mmΦ to 0.0:(
A line is drawn in mm. Line drawing die 7
The wire having a predetermined diameter that has exited the wire passes through a dry purse guide sheave 8 and is wound onto a take-up spool 9. In the present invention, as shown in FIG. 2, a branched blower tube 11 is disposed in the wire rod supply tube 5, and the blower tube 11 extends around the wire rod supply tube 5 toward the supply port side of the wire rod 2 to be processed. 45 from the surface
