この発明は、コイルスプリングの焼鈍方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of annealing a coil spring.
従来コイルスプリングを焼鈍する方法としては、炉内に
コイルスプリングを供給したのち、この炉内の温度を所
定温度（約３００℃）迄上昇させて行なっていた。Conventionally, the method of annealing a coil spring is to supply the coil spring into a furnace and then raise the temperature inside the furnace to a predetermined temperature (approximately 300° C.).
この場合、所定温度に昇温する迄の間の時間的なロスと
、焼鈍後の製品取り出しにともなう放熱で、次の焼鈍時
に再度昇温しなければならなかった。In this case, the temperature had to be raised again during the next annealing due to the time loss required to raise the temperature to a predetermined temperature and the heat dissipation associated with taking out the product after annealing.
この発明は、巻回されたコイルスプリングの搬送（排出
）途中において、通電により、上記コイルスプリングを
焼鈍するので、稼動率が向上し、かつ熱損失がない画劃
的な焼鈍方法を提供することにある。The present invention provides a unique annealing method that improves the operating rate and eliminates heat loss, since the coil spring is annealed by energization while the coil spring is being transported (discharged). It is in.
以下、この発明の実施例を添付図面に基いて説明する。Embodiments of the present invention will be described below with reference to the accompanying drawings.

ルスプリングＳが通過しない程度の間隔を有してかけ渡
した二条の通電性のある無端線材２と、この線材２に電
流を供給する通電装置３とによって構成されている。In the figure, A is an annealing device for coil springs S, and this annealing device A consists of a pair of pulleys 1 and two energized strips that are stretched across the pulleys 1 with an interval that prevents the coil springs S from passing through. It is composed of a flexible endless wire 2 and a current-carrying device 3 that supplies current to the wire 2.
また、線材２の間隔を、コイルスプリングＳの直径に応
じて調節できるようにするが、その手段としては、少く
とも一方のプーり１をスライドさせることにより行なう
ことができる。Further, the distance between the wire rods 2 can be adjusted according to the diameter of the coil spring S, which can be done by sliding at least one pulley 1.
尚図中４は、線材２の駆動装置である。In addition, 4 in the figure is a drive device for the wire rod 2.
次にこの発明の焼鈍方法を説明すると、線材２のキャリ

し、かつ設定寸法（長さ）になると切断するコイルスプ
リング製造機Ｂにより製造されたコイルスプリングＳを
杆材その他のシュート５から供給する。Next, to explain the annealing method of the present invention, a coil spring manufacturing machine B is used, which winds the supplied wire between the carrier-side tails of the wire 2 to a predetermined diameter and cuts it when the set dimension (length) is reached. The manufactured coil spring S is supplied from a chute 5 made of rod material or the like.
上記供給されたコイルスプ１ングＳは、線材２間で支持
されながらキャリャ側のヘッドに向けて搬送される。The supplied coil spring S is supported between the wire rods 2 and conveyed toward the head on the carrier side.
この搬送途中のゴイルスプリングＳは、線材２からの通
電により内部抵抗熱により加熱され、上記コイルスプリ
ングＳが搬送途中において焼鈍される。The Goyle spring S during the transportation is heated by internal resistance heat due to the electric current supplied from the wire rod 2, and the coil spring S is annealed during the transportation.
上記線材２のキャリャ側のヘッドからは、焼鈍ずみのコ
イルスプリングＳを排出する。The annealed coil spring S is discharged from the head of the wire rod 2 on the carrier side.
この発明の方法によれば、コイルスプリングを搬送する
二条の無端線材から上記のコイルスプリングに通電する
と、コイルスプリングの材質抵抗により内部抵抗熱を利
用して焼鈍される。According to the method of the present invention, when the coil spring is energized from the two endless wires carrying the coil spring, the coil spring is annealed using internal resistance heat due to the material resistance of the coil spring.
このため、コイルスプリングの製造機に、本発明の焼鈍
方法を接続すると、製造されたコイルスプリングの排出
搬送途中に於で、自動的に焼鈍を行なうことができるの
で、従来のように一々炉内にコイルスプリングを収納し
たのち、設定温度迄に昇温するために稼動率が低下する
ような不都合と、熱損失が大きい等の不都合を皆無とす
るすぐれた効果を有する。Therefore, when the annealing method of the present invention is connected to a coil spring manufacturing machine, the annealing can be performed automatically while the manufactured coil springs are being discharged and transported. This has an excellent effect of eliminating the inconveniences such as a decrease in the operating rate due to the temperature rising to the set temperature after the coil spring is housed in the coil spring, and inconveniences such as large heat loss.
また、搬送手段を構成する二条の無端線の間隔は、自由
に調節することができるので、コイルスプリングの直径
に制約を受けることがない。Further, since the interval between the two endless wires constituting the conveying means can be freely adjusted, there is no restriction on the diameter of the coil spring.
さらに、二条の無端線によりコイルスプリングを搬送す
るので、長いコイルスプリングでも伺ら支障なく搬送す
ることができる。Furthermore, since the coil spring is conveyed by two endless wires, even long coil springs can be conveyed without any trouble.
