Description
加工物搬送装置は、図面の矢印方向即ち、電極線2に対して直交する方向に移動し、電極線2は供給リール3から連続的に送出され、加工物の両端のガイドローラ5、5′を経て巻取リール4に巻き取られる。
黄銅合金の亜鉛含量が高いほど加工速度は向上すると思われるが、亜鉛含量が40%を超えると脆弱なβ相が形成されるので、細線にするときに引抜きが容易ではないという問題点がある。
このように形成された引張強度が低い芯線、即ち、相対的に軟らかい黄銅芯線が、延伸工程で発生する圧力によって、合金層のクラックを通じて溶岩湧出形状に亜鉛銅合金を突き抜いて表面の方へ迫り上がって亜鉛銅合金の細片粒を囲んだり覆うように形成することによって、放電加工のとき、加工速度は維持しながら細塵または細片屑の発生量が減る放電加工用電極線を提供することを目的にする。
本発明の他の目的は、このように電極線の表面に線材の長手方向に対して直角方向に、幅より長さが少なくとも2倍以上の長さの細片粒を形成することによって、放電加工のとき加工物の面粗度を向上させ、電極線の微塵発生を抑制するとともに速い加工速度を維持することができる放電加工用電極線を提供することである。
また、少なくとも前記第2合金材の細片粒は、前記芯線材質によって囲まれる形態を含むことを特徴とする。
また、前記メッキは、電気メッキ、溶融メッキまたは化学メッキ方法を利用する。
また、前記細片粒を形成する段階の放電加工用電極線を第2直径に細線して引抜きする前に該放電加工用電極線を上、下、左、右の何れか一方または複数の方向から曲げたりツイストさせる工程を追加することを特徴とする。
図2は、本発明の放電加工用電極線の製造方法を示す図である。先ず、図2に示すように、0.9〜1.2mm直径の銅65重量%、亜鉛35重量%からなる黄銅芯線12が提供される。
前記メッキ槽を通す方法の外に、電気メッキまたは化学メッキ方法等を利用して、3〜10μmほどの厚さに亜鉛がメッキされた黄銅の芯線を10〜60Vの電圧と100〜600m/minの速度で熱処理して、亜鉛メッキされた芯線12の引張強度を500N/mm2以下、延伸率は5%以上になるように形成することができる。
前記細線は、熱処理工程を経て機械的な性質をさらに安定化させることができる。
従って、このような亜鉛合金線材を放電加工用電極線として細線にするとき、芯線と合金層との間の延伸率の差によって合金層にクラックを容易に形成することができる。
中間線材、即ち、銅65重量%と亜鉛35重量%の成分比を有する黄銅線を直径0.9mmの芯線(第1金属)として準備する。
前記芯線に第2金属である亜鉛を利用して溶融亜鉛メッキを行なう。

前記芯線に第2金属である亜鉛を利用して溶融亜鉛メッキを行なう。
溶融亜鉛メッキの工程に利用される芯線を、アルカリ脱脂槽に浸漬、水洗い、酸性洗浄し、再び水洗いした後、塩化アンモニウムフラックス槽に浸漬する。
このように高温のメッキ槽に浸漬して溶融亜鉛メッキを行なうと、芯線が溶融亜鉛槽に浸漬されている間に該芯線の境界面から亜鉛との相互拡散反応によって銅亜鉛の合金層を構成する第1合金層22が形成され、その合金層の外郭には亜鉛銅の合金層を構成する第2合金層23が形成されるとともに軟質の芯線が製造される。
前記溶融亜鉛メッキおよび相互拡散によって、芯線表面の境界面には1〜3μmの銅亜鉛合金層からなる第1合金層が形成され、最外郭には3〜10μmの亜鉛銅合金層からなる第2合金層が形成される。
細線工程の前に中間線材をジグザグに曲げるツイスト装置33に通した後、前記中間線材は、引抜き細線工程を経て0.07〜0.35mmの直径を有する細線に製造される。
中間線材、即ち、銅65重量%と亜鉛35重量%の成分比を有する黄銅線を直径0.9mmの芯線(第1金属)として準備する。
前記芯線に第2金属である亜鉛を利用して電気亜鉛メッキを行なう。
電気亜鉛メッキ工程に利用される芯線は、アルカリ脱脂槽に浸漬、水洗い、酸性洗浄され、再び水洗いされた後、電気亜鉛メッキ槽に通される。
前記亜鉛銅の第2合金層は、一番硬度が高い部分であり、軟線の芯線より延伸率が低い。
前記引抜きされた細線の第2合金層は、芯線より硬度が高く延伸率が低いので引抜き細線の工程中に第2合金層が形成されている最外郭層の表面に多数のクラックが発生し、第2合金層は第1合金層を介して芯線の第1金属と界面をなす。
前記細線工程によって加工された放電加工用電極線は、300〜600℃の温度雰囲気で0.05〜3秒ぐらい再び熱処理を行なって芯線の機械的な性質を安定化させる。
中間線材、即ち、銅65重量%と亜鉛35重量%の成分比を有する黄銅線を、直径0.9mmの芯線(第1金属)として準備する。
前記芯線に第2金属である亜鉛を利用して電気亜鉛メッキを行なう。
電気亜鉛メッキ工程に利用される芯線は、アルカリ脱脂槽に浸漬、水洗い、酸性洗浄され、再び水洗いされた後、電気亜鉛メッキ槽に通される。
前記電気亜鉛メッキされた中間線材は、熱処理機に投入されて50〜60Vの電圧から155m/minの速度で熱処理されて、引張強度は500N/mm2以下、延伸率は5%以上になる芯線を製造する。
前記亜鉛銅の第2合金層は、一番硬度が高い部分であり、軟線の芯線より延伸率が低い。
