Description

【０００１】
【発明の属する技術分野】
本発明は、伸線した鋼線材に防錆処理を行う方法および装置、特に伸線した鋼線材に防錆油を塗布する方法および塗布装置に関する。
【０００２】
【従来の技術】
従来、軸受鋼鋼線などの製造においては伸線機による伸線後に、オフラインにおいて、防錆油槽に引き抜いた線材を浸漬して線材表面に防錆油を塗布した防錆処理して出荷する、すなわち、伸線→結束→防錆処理（油切り）→出荷するのが一般的である。伸線機の伸線ラインのオンライン上で防錆処理する場合には、銅線等では特開平５−２５０９３３号公報等に開示のようにベンゾトリアゾール（ＢＴＡ）溶液を入れた防錆処理層に線材を通して線材表面に付着して引き出し、次いで赤外線照射によりＣｕＢＴＡ膜を線材上に形成する方法や、ジェット噴流による吹き付けなどの方法があるが、このような方法は設備費用がかかる問題および線材表面の燐酸塩等の皮膜性能への影響の問題などを加味して軸受鋼鋼線などに適用されることは少なかった。
【０００３】
そこで軸受鋼鋼線などは、伸線機による伸線後に、伸線ラインのオフラインにおいて線材を巻き取った状態で防錆油槽に浸漬している。このため巻き取った線材コイルの線材間に防錆油が溜まり、ユーザーでの使用時に油量過多による防錆油の飛散を起こすなどの問題があった。さらに伸線ライン中に防錆油槽を設けると、伸線で使用する乾式潤滑材を吸着してしまい、乾式潤滑材が製品に付着し、ヘッダー加工時のヘドロカスが発生するという問題があった。
【０００４】
【発明が解決しようとする課題】
本発明が解決しようとする課題は、上記した従来の軸受鋼鋼線などの線材コイルを防錆油槽に浸漬した場合に生じる上記の問題点を解消することであり、防錆油槽への浸漬工程を省略し、油量過多を防止して線材使用時の防錆油の飛散をなくし、さらに防錆油の使用量を低減するとともに、伸線時の乾式潤滑材の付着によるヘッダー加工時のヘドロカスの発生をなくした防錆方法および装置の提供である。
【０００５】
【課題を解決するための手段】
上記の課題を解決するための本発明の手段は、請求項１の発明では、伸線ライン１において、引抜きダイス５により伸線した線材６を防錆油塗布装置１１内の前段部１７のスパイラル状ブラシ２３で埃や伸線の乾式潤滑剤を擦り落とし、擦り落とした埃や乾式潤滑材が後段部１８の防錆油２５に混入することを防止する区画壁１６の孔を通して後段部１８の防錆油２５を浸潤させたスパイラル状ブラシ２４中に通すことにより線材６の表面に防錆油２５を塗布し、次いで防錆油２５を塗布した線材６を防錆油の拭き取りボックス２６内のウエス３１の中に通すことにより線材６の表面の余分の防錆油２５を拭き取ることを特徴とする伸線した線材への薄く均一な防錆油膜の塗布方法である。
【０００６】
請求項２の発明では、伸線ライン１の伸線機４の引き抜きダイス５に続いて、長手方向の１端の前壁１４に伸線した線材の入口１９を有し他端の後壁１５に線材１０の出口２０を有し、内部を区画壁１６により前段部１７と後段部１８に区画し、前段部１７および後段部１８のそれぞれにスパイラル軸を長手方向に配したスパイラル状ブラシ２３、２４を内装し、後段部１８のスパイラル状ブラシ２４の上部の上壁１２に防錆油定量滴下孔２１を有し、後段部１８のスパイラル状ブラシ２４の下部の下壁１３に防錆油回収孔２２を有する長方形箱体からなる防錆油塗布装置１１を配設し、さらに該防錆油塗布装置１１の後段に長手方向の１端の前壁２７に伸線した線材６の入口２９を有し、他端の後壁２８に線材６の出口３０を有し内部にウエス３１を充満した長方形箱体からなる防錆油拭き取りボックス２６とを配設したことを特徴とする伸線した線材への薄く均一な防錆油膜の塗布装置である。
【０００７】
【発明の実施の形態】
本発明の実施の形態を図面を参照して説明する。図１は図２の伸線ライン１に配設した防錆油塗布・拭き取り装置７を拡大して内部を透視して示す模式図である。防錆油塗布・拭き取り装置７は前段の防錆油塗布装置１１および後段の防錆油拭き取りボックス２６からなっている。さらに、図２は伸線機の引き抜きダイスの後方に防錆油塗布装置および防錆油拭き取りボックスからなる防錆油塗布・拭き取り装置７を配設した伸線ラインの模式図である。図２において、本実施の形態における伸線ライン１は軸受鋼線の素材コイル２と、素材コイル２から巻きほぐした素材３を伸線機４の引き抜きダイス５と、引き抜きダイス５で引き抜いた伸線６をオンライン上で防錆油塗布・拭き取り装置７と、線材に引っ張り力を加える巻き取り胴８と、巻き取り胴８からの線材１０をさらにコイリングした製品コイルからなる。
【０００８】
防錆油塗布装置１１は長方形箱からなり、長方形箱は区画壁１６で前段部１７と後段部１８に区画されている。長方形箱の一端の前壁１４には引き抜きダイス５から引き抜きにより伸線された線材６を通す入口１９が開口されており、他端の後壁１５には防錆油２５を塗布した線材６の出口２０が開口されている。防錆油塗布装置１１の前段部１７と後段部１８にはそれぞれスパイラル軸を長手方向に配したスパイラル状ブラシ２３とスパイラル状ブラシ２４が装着されている。スパイラル状ブラシ２３とスパイラル状ブラシ２４はブラシの毛がスパイラルの軸芯に向けて設けられており、スパイラル状ブラシ２３、２４の毛先は軸芯を通る線材６の表面に接触するようになっている。後段部１８のスパイラル状ブラシ２４の上の上壁１２には防錆油２５を定量滴下する防錆油定量滴下孔２１が開口されており、スパイラル状ブラシ２４の下の下壁１３には防錆油を回収する防錆油回収孔２２が開口されている。
【０００９】
上記の防錆油塗布装置１１を形成する長方形箱は、区画壁１６で前段部１７と後段部１８に区画されているので、前段部１のスパイラル状ブラシ２３で埃や伸線の乾式潤滑剤を擦り落とし、後段のスパイラル状ブラシ２４で潤滑油を塗布することで、前段部１７の擦り落とした埃や乾式潤滑剤が後段部１８のオイルに混入することがない。
【００１０】
防錆油塗布装置１１に続く防錆油拭き取りボックス２６は長方形箱からなり内部に線材６の表面の余分の防錆油２５を拭い取るためのウエス３１が詰められている。長方形箱の一端の前壁２７には線材６を通す入口２９が開口されており、他端の後壁２８には拭い取られた線材６の出口３０が開口されている。
【００１１】
次いで、上記の装置を使用する本発明の請求項１に係る発明の実施の形態を説明する。素材コイル２の巻き戻しのアンコイラーから伸線機４で引き抜き伸線し巻き取り胴８で引き抜き力を付与し、再びリコイラーで製品コイル９の巻き回する工程からなる伸線ライン１において、軸受鋼線材の素材コイル２をアンコイラーで巻き戻し、巻き戻した素材を３を伸線機４の引き抜きダイス５に通して引き抜きにより伸線した線材６とし、伸線した線材６を長方形箱からなる防錆油塗布装置１１の前壁１４に開口した入口１９に通して、長方形箱内に設けた前段部１７のスパイラル状ブラシ２３および後段部１８のスパイラル状ブラシ２４の軸芯に挿通する。線材６の表面に付着した埃や引き抜きダイス６の乾式潤滑剤はスパイラル状ブラシ２３の毛先で擦すられて落される。次いで、区画壁１６を通して後段部１８内のスパイラル状ブラシ２４に通す。この後段部１８のスパイラル状ブラシ２４は後段部１８の上部の上壁１２に開口の防錆油適量滴下孔２１から滴下した防錆油２５で湿潤されている。従ってこのスパイラル状ブラシ２４に通すことで、線材６の表面はブラシの毛先で防錆油が塗布される。後段部１８で塗布した残りの余分の防錆油は下壁１３に設けた回収孔２２から回収される。防錆油を塗布した線材６が後壁１５に開口した出口から出ると、次いで、線材６は防錆油拭き取りボックス２６の長方形箱の前壁２７に開口の入口２９に通される。長方形箱内にはウエス３１が充満して収容されているのでそれらの間に線材６を通すことで、線材６の表面に塗布された余分の防錆油はウエス３１と接触することで拭い取られて適量の防錆油が塗布された状態となり、後壁に開口の出口３０から出され、防錆油塗布工程は終了し、次いでその後方に配置の巻き取り胴８に２回ないし３回周回され線材６に引き抜きダイス５に対する引き抜き力が付与される。再びリコイラーにより巻き回し、製品コイル９として結束して出荷される。
【００１２】
上記の方法において、引き抜きダイスから出た伸線した線材６の表面に付着した埃や残存コーシン等は物理的にスパイラル状ブラシ２３で除去するので、これらが防錆油と混合して線材に付着することがない。さらに本発明では防錆油を吹付ける、滴下する、槽に漬けるなどの方法と異なり、スパイラル状ブラシ２４で塗る方法なので全体に薄く均一に防錆油膜をつけることができ、また余分な防錆油は後の防錆油拭き取りボックス２６で除去できより一層均一に薄く塗布でき、加熱による乾燥等を必要としないため、設備費用がかからず皮膜性能を損なうことなく防錆処理が行なえ、伸線（防錆、拭き取り）→結束→出荷の工程が、オフラインを経ることなくオンラインで一気に行えるので極めて効率的である。
【００１３】
【発明の効果】
以上説明したとおり、本発明は、軸受鋼鋼線等の鋼線材の引き抜きにおいて、引き抜きライン上で、防錆処理が実施でき、オフラインを経ないので、効率よく、安価に実施でき、さらに防錆油を極めて均一に薄く塗布できるので、油膜過多が防止できて加熱による乾燥を不必要とし、従って設備費もかかることなく、伸線時の乾燥潤滑剤の付着によるヘッダー加工時のヘドロカスの発生もなく、防錆油の使用量を低減でき、品質のよい伸線鋼線を得ることができるなど、従来にない優れた効果を奏する。

Furthermore, FIG. 2 is a schematic diagram of a wire drawing line in which a rust preventive oil coating / wiping device 7 comprising a rust preventive oil coating device and a rust preventive oil wiping box is arranged behind the drawing die of the wire drawing machine. In FIG. 2, the wire drawing line 1 in this embodiment includes a material coil 2 of a bearing steel wire, a material 3 unwound from the material coil 2, and a wire drawing machine 5 with a drawing die 5 and a drawing die 5. The wire 6 includes a rust preventive oil application and wiping device 7 on-line, a winding cylinder 8 for applying a tensile force to the wire, and a product coil obtained by further coiling the wire 10 from the winding cylinder 8.
[0008]
The rust preventive oil coating device 11 is formed of a rectangular box, and the rectangular box is divided into a front stage portion 17 and a rear stage portion 18 by a partition wall 16. The front wall 14 at one end of the rectangular box has an inlet 19 through which the wire 6 drawn from the drawing die 5 is drawn, and the rear wall 15 at the other end is coated with a rust preventive oil 25. The outlet 20 is opened. A spiral brush 23 and a spiral brush 24 each having a spiral axis arranged in the longitudinal direction are attached to the front stage portion 17 and the rear stage portion 18 of the rust preventive oil coating apparatus 11. The spiral brush 23 and the spiral brush 24 are provided such that the bristles of the brush are directed toward the spiral axis, and the tips of the spiral brushes 23 and 24 come into contact with the surface of the wire 6 passing through the axis. ing. The upper wall 12 above the spiral brush 24 of the rear stage portion 18 is provided with a rust preventive oil quantitative dropping hole 21 for quantitatively dropping the rust preventive oil 25, and the lower wall 13 below the spiral brush 24 is protected against the bottom wall 13. A rust preventive oil recovery hole 22 for recovering rust oil is opened.
[0009]

In the wire drawing line 1 comprising the steps of drawing the wire coil 2 from the uncoiler of the material coil 2 with the wire drawing machine 4 and applying the drawing force with the winding drum 8, and again winding the product coil 9 with the recoiler. The wire material coil 2 is rewound with an uncoiler, and the rewound material 3 is passed through a drawing die 5 of a wire drawing machine 4 to obtain a wire 6 drawn by drawing, and the drawn wire 6 is made of a rectangular box. It passes through the inlet 19 opened in the front wall 14 of the oil application device 11 and is inserted into the shafts of the spiral brush 23 in the front stage 17 and the spiral brush 24 in the rear stage 18 provided in the rectangular box. The dust adhering to the surface of the wire 6 and the dry lubricant of the drawing die 6 are rubbed off by the hair tips of the spiral brush 23 and dropped. Next, it passes through the partition wall 16 and the spiral brush 24 in the rear stage 18. The spiral brush 24 of the rear stage portion 18 is wetted with an antirust oil 25 dripped from an appropriate amount of the antirust oil dropping hole 21 on the upper wall 12 of the upper portion of the rear stage portion 18. Accordingly, by passing through the spiral brush 24, the surface of the wire 6 is coated with antirust oil at the brush tip. The remaining excess rust preventive oil applied at the rear stage 18 is recovered from a recovery hole 22 provided in the lower wall 13. When the wire 6 coated with rust-preventing oil exits from the outlet opening in the rear wall 15, the wire 6 is then passed through the opening 29 in the front wall 27 of the rectangular box of the rust-preventing oil wiping box 26. Since the waste box 31 is filled and accommodated in the rectangular box, the extra rust preventive oil applied to the surface of the wire 6 is wiped off by contacting the waste 31 by passing the wire 6 between them. In this state, an appropriate amount of anticorrosive oil is applied, and the rear wall is opened from the outlet 30 of the opening, and the antirust oil application process is completed, and then the winding cylinder 8 disposed behind the anticorrosive oil is applied 2 to 3 times.
